1 This files describes API changes in core libraries and APIs,
2 information provided here is intended especially for developers.
6 * Added modalform config object `moduleName` param that can be used to define alternative modal type for the modalform. By default 'core/modal_save_cancel' is used.
7 * Add a new parameter to the debounce (core/utils) function to allow for cancellation.
8 * Add a new method core_user::get_initials to get the initials of a user in a way compatible with internationalisation.
9 * The `core/sortable_list` JS module adds a `sortable-list-is-dropped` class onto the dropped element after successful
10 drag/drop, which can be used to add transition effects in calling code
11 * course_modinfo now has a purge_course_modules_cache() method, which takes a list of cmids and purges
12 them all in a single cache set.
13 * Behat generators can now implement the function finish_generate_ to detect when the whole list of elements have been generated.
14 * New return value 'icon' has been added to the 'external_files' webservice structure. This return value represents the
15 relative path to the relevant file type icon based on the file's mime type.
16 * Removed the sesskey passed from manageauths and manageenrols to their respective test_settings.php pages.
17 * The following previously deprecated methods have been removed and can no longer be used:
18 - `download_as_dataformat`
19 * In enrollib.php, the method enrol_get_course_users() got an optional 5th parameter $usergroups that
20 defaults to an empty array. Here, user group ids can be provided, to select enrolled users in a course
21 that are also members of these groups.
22 * The options for `format_string()`, and `format_text()` are now checked for incorrectly passed context objects.
23 Please note that this was never an accepted value but previously failed silently.
24 * The current page language is available in new `core/config` language property for Javascript modules
25 * The `html_writer::select_time` method has a `$timezone` parameter to use when formatting the time parameter
26 * The following functions have been added to adhoc_task class:
27 - retry_until_success(): Used to indicate if the task should be re-run if it fails
28 By default, tasks will be retried until they succeed, other tasks can override this method to change this behaviour.
29 - set_attempts_available(): Used to set the number of attempts available for the task
30 - get_attempts_available(): Used to get the number of attempts available for the task.
31 * There is a new DML method $DB->get_fieldset. For some reason, this did not exist even though get_fieldset_select etc. did.
32 * The following callbacks have been migrated to hooks:
33 - before_standard_html_head() -> core\hook\output\standard_head_html_prepend
34 * Deprecated PARAM_ types with the exception of PARAM_CLEAN now emit a deprecation exception. These were all deprecated in Moodle 2.0.
35 * A new \core\deprecated attribute can be used to more clearly describe deprecated methods.
36 * A new \core\deprecation class can be used to inspect for deprecated attributes:
37 - `\core\deprecation::is_deprecated(example::class);`
38 - `\core\deprecation::emit_deprecation_if_present([self::class, 'some_method']);`
39 * Added missing deprecation for PARAM_CLEANFILE which was deprecated in Moodle 2.0.
40 * New Behat `heading` named selector to more easily assert the presence of H1-H6 elements on the page
41 * Login can now utilise new param 'loginredirect' to indicate when to use value set for $CFG->alternateloginurl.
42 * \action_menu_link::$instance has been deprecated as it is no longer used.
46 * Unnecessary parameters of admin_apply_default_settings() function were removed; upgrade script lists
47 setting names in the same format as admin UI; default setting writing errors now trigger debugging messages;
48 duplicate setting names (with different plugin part) in one setting page do not cause problems any more.
49 * Added a new render of caption for the table in render_caption. It can be used by
50 set_caption($caption, $captionattributes).
51 e.g. $caption = 'Caption for table'
52 e.g. $captionattributes = ['class' => 'inline'];
53 * Admin settings for passwords (admin_setting_configpasswordunmask) can now be a required field using the following class:
54 - admin_setting_requiredpasswordunmask
55 * The `$a` argument passed to `get_string` can now include any stringable type, removing the need for explicit casts (for
56 example, of `\moodle_url` instances)
57 * The badges_get_oauth2_service_options() method has been deprecated, because it's not required anymore. It should no longer
59 * The following class constants are deprecated, as Sodium is now required and we no longer support the OpenSSL fallback except
60 when decrypting existing content for backwards compatibility:
61 - `\core\encryption::METHOD_OPENSSL`
62 - `\core\encryption::OPENSSL_CIPHER`
63 * The `\core\encryption::is_sodium_installed` method is deprecated, as Sodium is now a requirement
64 * The `drop_plugin_tables` method now returns immediately after deleting tables defined by plugin XMLDB file
65 * Support for the following phpunit coverage info properties, deprecated since 3.11, has been removed:
68 * The following previously deprecated methods have been removed and can no longer be used:
69 - `get_extra_user_fields`
70 - `get_extra_user_fields_sql`
71 - `get_user_field_name`
72 - `get_all_user_name_fields`
75 * Added a new parameter in address_in_subnet to give us the ability to check for 0.0.0.0 or not.
76 * New method moodleform::add_sticky_action_buttons() is created to enable sticky footer for QuickForms.
77 * Added new \admin_setting::is_forceable() method to determine whether the setting can be overridden or not. Therefore,
78 whether the settings can be overriden or not will depend on the value of implemented \admin_setting::is_forceable() method,
79 even if we define the settings in config.php.
80 * New core_renderer::paragraph method to replace the overused html_writer::tag('p', ...) pattern.
81 * All functions associated with device specific themes have been deprecated.
82 - core_useragent::get_device_type_theme()
83 - core_useragent::get_device_type_cfg_var_name()
84 - theme_is_device_locked()
85 - theme_get_locked_theme_for_device()
86 * Addition of new 'name' field in the external_tokens table.
87 * \core_external\util::generate_token() has a new optional argument "name" used as a token name.
88 * Introduce a new public function \core_external\util::generate_token_name()
89 * Legacy (and custom) Behat --skip-passed option has been removed completely. Please, use the standard
90 --rerun option that provides exactly the same (execution of failed scenarios only).
91 * Allowed database identifier lengths have been raised:
92 - From 28 characters to 53 for table names (xmldb_table::NAME_MAX_LENGTH).
93 - From 30 characters to 63 for column names (xmldb_field::NAME_MAX_LENGTH).
94 - Maximum length for table prefixes has been set to 10 characters (xmldb_table::PREFIX_MAX_LENGTH). And it's enforced
95 by environmental checks.
96 * New scheduled tasks show_started_courses_task and hide_ended_courses_task that updates the course visibility when the current
97 day matches course start date/end date. They are disabled by default. Once they are enabled, only courses with start/end dates
98 near the past 24 hours will be checked. The visibility of these courses will only changed when their start/end dates are higher
99 than the current one, to avoid updating the course visibility early.
100 * New events course_started and course_ended have been created. For now, they are triggered when courses change automatically their
101 visibility through the new scheduled tasks to hide/show courses based on their start/end dates.
102 * The action_menu::set_constraint() method is deprecated. Please use action_menu::set_boundary() instead.
103 * New \core\output\activity_header::get_heading_level() method to get the heading level for a given heading level depending whether
104 the page displays a heading for the activity (usually a h2 heading containing the activity name).
105 * New method moodleform::filter_shown_headers() is created to show some expanded headers only and hide the rest.
106 * count_words() and count_letters() have a new optional parameter called $format to format the text before doing the counting.
107 * New core_renderer::sr_text method to generate screen reader only inline texts without using html_writer.
108 * New events \core\event\qbank_plugin_enabled and \core\event\qbank_plugin_disabled are triggered when a qbank plugin is enabled or
109 disabled respectively, with the plugin's frankenstyle name. Any plugins that need to perform an action in response to a qbank
110 plugin being enabled or disabled should observe these events.
111 * Code calling to qbank plugins was moved from question_delete_question in questionlib.php into the plugins themselves. Any plugins
112 that need to perform processing when a question is deleted should observe the \core\event\question_deleted event instead.
113 * The external function core_grades_get_groups_for_selector is now relocated.
114 Please use it at core_group_get_groups_for_selector instead.
115 * The M.util.show_confirm_dialog function has been rewritten as an ESM to use the core/notification module instead.
116 See MDL-77174 for further information.
117 * The moodle-core-notification-confirm module, found under the M.core.confirm namespace, has been deprecated.
118 Any code using it should be rewritten as an ESM and use the core/notification module instead.
119 See MDL-77174 for further information.
120 * New set of output generic components. Check the component library for more information:
121 - core\output\local\action_menu\subpanel to add subpanels to action menus.
122 - core\output\local\dropdown\dialog to display HTML inside a dropdown element.
123 - core\output\local\dropdown\status to render a user choice into a dropdown.
124 - core\output\choicelist class to render a list of user choices. It combines with dropdown status and action menu subpanels.
125 * The behat step I choose "WHATEVER" in the open action menu is now compatible with action menus subpanels
126 using the ">" symbol to suparate the item link text and subitem one. For example:
127 - I choose "Group mode > Visible groups" in the open action menu
128 * addHelpButton() function has a new optional $a parameter to allow variables with translation strings.
129 * help_icon constructor has a new optional $a parameter to allow variables with translation strings.
130 * The random_bytes_emulate() function has been deprecated, because it's not required anymore. PHP native function random_bytes()
131 should be used instead.
132 * New behat behat_navigation::i_close_block_drawer_if_open() and behat_navigation::i_keep_block_drawer_closed()
133 to ensure in some test that the block drawer is closed. This helps with random failures due to the block drawer
134 being forced open in all behat tests.
135 * The core_useragent::get_device_type_list() function has been deprecated. Use core_useragent::devicetypes instead as a replacement.
136 * The parameter $size of the following functions has been deprecated and is not used any more:
137 - file_extension_icon
143 * The xxxxxxx-yyy.png MIME icons placed in pix/f have been removed and replaced with new SVG files.
144 In order to reduce the number of icons for the MIME types, a few MIME icons have been removed and
145 replaced with their generic from the existing ones:
159 Apart from that, the following MIME icons have been completely removed:
160 - clip-353 --> It was added in MDL-75362 by mistake.
168 * The signature of the static method `can_user_share` in the `core\moodlenet\local\can_share_manager` class has been updated to include an additional parameter `$type`.
169 This parameter specifies the type of resource being checked for sharing capabilities, which can either be 'activity' or 'course'.
170 * The method 'share_activity' in 'core\moodlenet\activity_sender' class has been deprecated and renamed to 'share_resource'. The method signature is the same as before and
171 the new method is coming from the base class 'core\moodlenet\resource_sender'.
172 * Final deprecation and removal of legacy cron. This includes the functions:
173 - cron_execute_plugin_type()
174 - cron_bc_hack_plugin_functions()
175 Please, use the Task API instead: https://moodledev.io/docs/apis/subsystems/task
176 * Final deprecation and removal of the following classes:
177 - \core\task\legacy_plugin_cron_task
178 - \mod_quiz\task\legacy_quiz_reports_cron
179 - \mod_quiz\task\legacy_quiz_accessrules_cron
180 - \mod_workshop\task\legacy_workshop_allocation_cron
181 Please, use the Task API instead: https://moodledev.io/docs/apis/subsystems/task
182 * New method login_captcha_enabled() is created to check whether the login captcha is enabled or not.
183 * New method validate_login_captcha() is created to validate the login captcha.
184 * A new parameter $loginrecaptcha has been added to the authenticate_user_login() to check whether the login captcha is needed to verify or not. The default value is false.
185 * A new parameter $compactmode has been added to the recaptcha_get_challenge_html() to define whether the reCaptcha element should be displayed in the compact mode or not.
186 Default value is false.
187 * A new native event in the `core_filters/events` AMD module eventTypes.filterContentRenderingComplete has been created to determine when the filter is complete the rendering.
188 * New parameters for \get_time_interval_string():
189 - `$dropzeroes` - Passing `true` will exclude zero date/time units from the output.
190 - `$fullformat` - Passing `true` will return date/time units in full format (e.g. `1 day` instead of `1d`).
191 * The print_object function (for temporary debugging use only) can now be used on objects that have recursive references,
192 and has an improved display and other changes. (New parameters are available; see function documentation.)
193 * New `filteroptions` field added to getFilterValue() in core/datafilter/filtertype. This is generated by `get filterOptions()`
194 and returns an arbitrary list of options specific to the filter type, in [{name:, value}] format. This allows filters to extend
195 the values returned with additional fields.
196 * New `required` field added to core\output\datafilter. This will be output via the data-required property in filter_type.mustache,
197 any additional filter types will need to output this property as well. Filters with data-required="1" will not be removable from
199 * addFilterRow() in core/datafilter now accepts a filterdata object to add a row with a pre-defined filter.
200 * New "binary" datafilter type added for creating filters with a single yes/no option.
201 * New "joinlist" parameter added to core\output\datafilter::get_filter_object(). This takes an array of datafilter::JOINTYPE_*
202 constants to define which types of join the filter supports. By default this will include all three of "Any", "All" and "None",
203 but a subset can be specified instead.
204 * core/form-autocomplete now supports disabled options in the source select list. These will be displayed in the autocomplete
205 options with the aria-disabled attribute, and will not be selectable.
206 * The method grade_item::set_locked() now returns true if the grade item needs to be updated. The method schedules the locking of
207 the grade item once the recalculations are completed. (This was fixed in 4.3, 4.2.2)
208 * Added a new constant called MAX_PASSWORD_CHARACTERS in moodlelib.php to hold a length of accepted password.
209 * Added a new method called exceeds_password_length in moodlelib.php to validate the password length.
210 * The core/modal_factory has been deprecated. From Moodle 4.3 onwards pleáse instantiate new modals using the ModalType.create method instead.
211 Please note that this method does not support the `trigger` option.
212 * \moodle_page::set_title() has been updated to append the site name depending on the value of $CFG->sitenameintitle and whether
213 the site's fullname/shortname has been set. So there's no need to manually add the site name whenever calling $PAGE->set_title().
214 If it's necessary to override this, pass `false` to its new optional parameter `$appendsitename`.
215 * New page title separator constant `moodle_page:TITLE_SEPARATOR` has been created to help standardise the separators used in page
217 * New Behat step \behat_general::the_page_title_should_contain() has been added to allow checking of page titles. You can use this
218 when writing feature files to check that the page title contains the expected string.
219 e.g. `And the page title should contain "Some title"`
220 * Ensure that all system icons now come with an accompanying SVG file. Any missing SVG files have been addressed, and to maintain
221 this consistency, a PHPUnit test has been implemented to validate the inclusion of SVG files for any new icons.
222 * The $CFG->svgicons setting has been removed because all modern browsers now handle SVG files correctly.
223 * The method `\core_renderer->supportemail()` has an updated signature. It now allows a second optional parameter.
224 Set it to true if you want to embed the generated link in other inline content.
225 * The users_search_sql function parameter $searchanywhere has been change to $searchtype for different type of search. $searchtype is a int parameter and has three constant value:
226 USER_SEARCH_STARTS_WITH: 0, USER_SEARCH_CONTAINS: 1, USER_SEARCH_EXACT_MATCH: 2
227 See MDL-78312 for further information.
228 * Function course_modinfo::clear_instance_cache now has an extra optional parameter $newcacherev, although this is really
229 intended only for use by rebuild_course_cache.
233 * All context classes were moved to \core\context namespace while keeping full backwards compatibility.
234 Please note it is not necessary to update plugins unless they rely on exact class names returned from
235 get_class() or context_helper.
236 * Travis CI integration has been removed from core (MDLSITE-7135). Please, use GitHub Actions (GHA) instead. For
237 more information visit https://moodledev.io/general/development/tools/gha
238 * A new constant COMPLETION_COMPLETE_FAIL_HIDDEN is introduced to mark that user has received a failing grade
239 for a hidden grade item. This state returned by internal_get_grade_state() and is only used by get_core_completion_state()
240 for processing the passgrade completion data.
241 * \single_button constructor signature has been changed to manage more types than just primary buttons.
242 The boolean "primary" parameter has been deprecated and replaced by a more generic type allowing to use
243 Bootstrap styles of buttons (danger, warning...). The constructor will still manage the boolean primary
244 parameter but will display a debugging message.
245 * In enrollib.php, the methods get_enrolled_with_capabilities_join, get_enrolled_sql, get_enrolled_users and
246 count_enrolled_users used to only be able to accept a single group id, even though internally, they used
247 groups_get_members_join which could also accept an array of groups, or the constant USERSWITHOUTGROUP.
248 This has now been made consistent. These enrol methods now accept all the group-related options that
249 groups_get_members_join can handle.
250 * assign_capability() now has an optional $performancehints parameter which can be used in
251 situations where it is being called in a loop in response to a database query, to reduce the
252 amount of checks it has to do.
253 * New DB parameter 'versionfromdb', only available for MySQL and MariaDB drivers. It allows to force the DB version to be
254 evaluated through an explicit call to VERSION() to skip the PHP client version which appears to be sometimes fooled by the
255 underlying infrastructure, e.g. PaaS on Azure.
256 * The actionmenu component has now a set_kebab_trigger that will setup the action menu for use in kebab menus.
257 * The useexternalyui configuration setting has been removed as a part of the migration away from YUI.
258 It only worked with http sites and did not officially support SSL, and is at risk of disappearing should Yahoo! decide
260 * New `properties_filter` method of persistent class for filtering properties of a record against persistent definition
261 * Added 'extrainfo' in the DB options config. Its extra information for the DB driver, e.g. SQL Server
262 has additional configuration according to its environment, which the administrator can specify to alter and
263 override any connection options.
264 * In outputcomponents.php, initials_bar() can now be rendered in a smaller (mini) way. This provides purely the
265 initials bar without the bootstrapping and form handling on each initials bar. If you use this mini render,
266 you'll need to implement your own form handling. Example usage can be found within the grader report.
267 * There is a new helper function mtrace_exception to help with reporting exceptions you have caught in scheduled tasks.
268 * Box/Spout has been archived and is no longer maintained, so it has now been removed and replaced by OpenSpout.
269 * The following parts of the external API have been moved to the core_external subsystem:
271 - external_api => core_external\external_api
272 - external_description => core_external\external_description
273 - external_files => core_external\files
274 - external_format_value => core_external\external_format_value
275 - external_function_parameters => core_external\external_function_parameters
276 - external_multiple_structure => core_external\external_multiple_structure
277 - external_settings => core_external\external_settings
278 - external_single_structure => core_external\external_single_structure
279 - external_util => core_external\util
280 - external_value => core_external\external_value
281 - external_warnings => core_external\external_warnings
282 - restricted_context_exception => core_external\restricted_context_exception
284 - external_format_string() => core_external\util::format_string()
285 - external_format_text() => core_external\util::format_text()
286 - external_create_service_token() => core_external\util::generate_token()
287 - external_generate_token() => core_external\util::generate_token()
288 - external_generate_token_for_current_user()
289 => core_external\util::generate_token_for_current_user()
290 - external_log_token_request => core_external\util::log_token_request()
292 The old class locations have been aliased for backwards compatibility and will emit a deprecation notice in a future
294 * The following methods, deprecated since 3.10, have been removed and can no longer be used:
295 - `\core\output\mustache_helper_collection::strip_blacklisted_helpers`
296 - `\core_form\filetypes_util::is_whitelisted`
297 - `\core_form\filetypes_util::get_not_whitelisted`
298 * Convert a floating value to an integer in lib/graphlib.php to avoid PHP 8.1 deprecated function error.
299 * The $required parameter for \core_external\external_description is now being validated in order to prevent
300 unintentionally passing incorrect parameters to the external_description's (and its subclasses') constructors (e.g. the parameter
301 description being incorrectly passed for the $required parameter). A debugging notice will be shown when such cases occur.
302 * The moodle-core-popuphelp YUI modal has been removed. It has not been actively used in Moodle since 3.3. It should be replaced with appropriate ESM/AMD JavaScript.
303 * The moodle-core-tooltip YUI modal has been removed. It should be replaced with appropriate ESM/AMD JavaScript.
304 * A `\core\event\role_created` event is now triggered when roles are created via the `create_role` API.
305 * Event \core\event\user_created is now triggered if the user is created during course restore. In this case
306 $event->other has properties 'restoreid' and 'courseid'.
307 * The core/modal module and all their versions (SAVE_CANCEL, DELETE_CANCEL...) now has a setButtonDisable to disable or enable
308 specific modal action buttons. This function allows developers to have modals that could only be submited if the user do some
309 action in the modal body like ticking a checkbox or selecting an element.
310 * Course module indentation has been recovered for course format using components via Move right/left feature.
311 Course formats using components will be allowed to use one level indentation only.
312 * The method `flexible_table::set_columnsattributes` now can be used with 'class' key to add custom classes to the DOM.
313 * The editor_tinymce plugin has been removed from core.
314 * A new grunt task, upgradablelibs, has been added to get the list of libraries that have a newer version in their repositories.
315 * Support for serving of AMD modules built in really old versions of Moodle (<= 3.8) has been removed.
316 Please ensure that your AMD modules have been rebuilt with a supported Moodle version.
317 * Addition of new 'visibility' and 'participation' fields in the groups table, and 'moodle/group:viewhiddengroups' capability.
318 The following grouplib functions will now return groups and members based on group visibility and the user's permissions:
319 - groups_get_all_groups()
320 - groups_get_user_groups()
321 - groups_get_my_groups()
323 - groups_get_members()
324 - groups_get_groups_members()
325 groups_print_activity_menu() will now only return groups where particiation == true.
326 * Cron utility functions have been moved from the global namespaces to the \core\cron class, these include:
327 - cron_setup_user() => \core\cron::setup_user()
328 - cron_run() => \core\cron::run_main_process()
329 - cron_run_scheduled_task() => \core\cron::run_scheduled_tasks()
330 - cron_run_adhoc_task() => \core\cron::run_adhoc_tasks()
331 - cron_run_inner_scheduled_task() => \core\cron::run_inner_scheduled_task()
332 - cron_run_inner_adhoc_task() => \core\cron::run_inner_adhoc_task()
333 - cron_set_process_title() => \core\cron::set_process_title()
334 - cron_trace_time_and_memory() => \core\cron::trace_time_and_memory()
335 - cron_prepare_core_renderer() => \core\cron::prepare_core_renderer()
336 * The `run_scheduled_tasks` and `run_adhoc_tasks` functions take an additional parameter to calculate the start of a run.
337 * The following phpunit advanced testcase helper methods, deprecated since 3.10, have been removed and can no longer be used:
340 - `createArrayDataSet`
342 * The external function core_grades_get_enrolled_users_for_search_widget is now deprecated.
343 Please use the new core_grades_get_enrolled_users_for_selector external function instead.
344 * The external function core_grades_get_groups_for_search_widget is now deprecated.
345 Please use the new core_grades_get_groups_for_selector external function instead.
346 * New \core_component::has_monologo_icon() that determines whether a plugin has monologo icons. This can be used to
347 determine whether to apply CSS filtering to the plugin's icon when rendering it.
348 * \cm_info::get_icon_url() resolves the icon's file type and adds a `filtericon` parameter in the URL when rendering the monologo
349 version of the course module icon or when the plugin declares, via its `filtericon` custom data, that the icon needs to be
350 filtered. This additional information can be used by plugins when rendering the module icon to determine whether to apply
351 CSS filtering to the icon.
352 * Activity plugins displaying activity module icons using \cm_info::get_icon_url() can declare the `filtericon` custom data in their
353 `get_coursemodule_info()` callback. If set, this will be used by \cm_info::get_icon_url() to set the icon URL's `filtericon`
354 parameter. This information can be used by the plugins when enclosing the icons in `.activityiconcontainer .icon` or
355 `.activityiconcontainer .activityicon` containers to determine whether CSS filtering should be applied to the icon. If the icon
356 needs to be rendered as is and not whitened out, the `.nofilter` CSS class needs to be applied to the icon.
357 * New moodle_url::export_params_for_template() returns the params as an array of key => value pairs. You should use this when
358 you want to pass URL params to a template. An example can be found in single button.
359 * Functions get_next_adhoc_task() and cron::run_adhoc_tasks() have additional parameter $classname to filter by the specified class.
360 * Function cron::run_adhoc_tasks() has additional parameter $number to limit the number of the tasks to run.
361 * Function get_adhoc_tasks() has additional parameter $failedonly to return only failed tasks.
362 * admin/cli/adhoc_task.php has additional parameters:
363 - id - to run individual tasks by id
364 - classname - to run tasks by classname
365 - taskslimit - to limit the number of tasks in one run
366 - failed - to limit the run to only the tasks that failed in their previous run
367 Can be mixed, apart from 'id' of course.
368 * The file_system class now declares a new, optional, `get_psr_stream` function which allows a Stream implementing `\Psr\Http\Message\StreamInterface` to be returned.
369 A default implementation which uses the existing file handle resource is used by default, but this should be extended by file_system implementations where relevant.
373 * HTMLPurifier has been upgraded to the latest version - 4.16.0
374 * A process to deprecate capabilities by flagging them in the access.php by adding a $deprecatedcapabilities variable (an array).
375 This array will list the deprecated capabilities and a possible replacement. Once we declare the capability as deprecated, a debugging
376 message will be displayed (in DEBUG_DEVELOPPER mode only) when using the deprecated capability.
377 Declaration is as follow:
378 $deprecatedcapabilities = [
379 'fake/access:fakecapability' => ['replacement' => '', 'message' => 'This capability should not be used anymore.']
381 * coursemodinfo cache uses the new `requirelockingbeforewrite` option, and rebuilding the cache now uses the cache lock API, rather
382 than using the core lock factory directly. This allows the locks to be stored locally if the cache is stored locally, and
383 avoids the risk of delays and timeouts when multiple nodes need to rebuild the cache locally, but are waiting for a central lock.
384 * Final deprecation and removal of the class \admin_setting_managelicenses, please use \tool_licensemanager\manager instead.
385 * Final deprecation and removal of the function license_manager::add(). Please use license_manager::save() instead.
386 * Final deprecation of the following functions behat_field_manager::get_node_type() and behat_field_manager::get_field()
387 please call behat_field_manager::get_field_node_type() and behat_field_manager::get_form_field().
388 * Final deprecation and removal of the following class, please use \core\task\manager.
389 - \tool_task\run_from_cli
390 * Final deprecation and removal of the following CLI scripts:
391 - admin/tool/task/cli/schedule_task.php please use admin/cli/scheduled_task.php
392 - admin/tool/task/cli/adhoc_task.php please use admin/cli/adhoc_task.php
393 * Final deprecation and removal of cron_run_single_task(), please use \core\task\manager::run_from_cli().
394 * The $USER->groupmember hack that fills the user object with the groups that the user belongs to has been removed.
395 Please use the Groups API function groups_get_user_groups() to fetch the cached list of groups the user is a member of.
396 * The following functions, previously used (exclusively) by upgrade steps are not available anymore
397 because of the upgrade cleanup performed for this version. See MDL-71747 for more info:
398 - upgrade_analytics_fix_contextids_defaults()
399 - upgrade_convert_hub_config_site_param_names()
400 - upgrade_rename_prediction_actions_useful_incorrectly_flagged()
401 * The method ensure_adhoc_task_qos() in lib/classes/task/manager.php has been deprecated, please use get_next_adhoc_task()
403 * New setting $CFG->enrolments_sync_interval controls the minimum time in seconds between re-synchronization of enrollment via enrol_check_plugins.
404 This only applies to web requests without a session such as webservice calls, tokenpluginfile.php and rss links Function
405 enrol_check_plugins now has $ignoreintervalcheck flag to bypass checking for that setting.
406 * For performance reasons, sql_reader interface has a new function get_events_select_exists() which determines whether
407 an event exists with the given criteria (see MDL-72723 for details).
408 - Breaking: 3rd party log readers implementing interface sql_reader will need to implement get_events_select_exists()
409 * Added $strictness parameter to persistent `get_record` method, optionally allowing caller to ensure record exists
410 * New DML driver method `$DB->sql_cast_to_char` for casting given field/expression to char
411 * The core renderer `edit_button` method now accepts an optional `$method` argument (get/post) for the button
412 * For plugins that override secondary navigation, the namespace for the custom secondary navigation class has
413 changed. It was (for example) mod_mymodule\local\views\secondary but is now
414 mod_mymodule\navigation\views\secondary. The old location will continue to work, but is deprecated.
415 * The check for $plugin->incompatible was found to be incorrect. The $plugin->incompatible attribute is meant to define the minimum
416 Moodle version the plugin is incompatible with but the implemented logic for the check was the opposite. Plugins declaring this
417 attribute may encounter different behaviours between older Moodle versions (<v3.11.8, <v4.0.2) and the later ones. We recommend
418 plugin developers to not use this attribute for Moodle versions 4.0 and below in order to avoid this problem.
419 * Added $CFG->proxylogunsafe and proxyfixunsafe to detect code which doesn't honor the proxy config
420 * Function admin_externalpage_setup() now has additional option 'nosearch' allowing to remove Site administration search form.
421 * The function print_error has been deprecated. Kindly use moodle_exception.
422 * When exporting table content, HTML tags/entities will be removed when the selected dataformat does not support HTML
423 * The abstract `get_name` method has been moved from `\core\task\scheduled_task` to the `\core\task\task_base` class and can now be
424 implemented by adhoc tasks. For backwards compatibility, a default implementation has been added to `\core\task\adhoc_task` to
425 return the class name.
426 * The function get_module_metadata() has been finally deprecated and can not be used anymore.
427 * New DML driver method `$DB->sql_order_by_null` for sorting nulls sort nulls first when ascending and last when descending.
428 * Allow plugins to callback on all pages just prior to the session start.
429 * New function set_additional_classes() has been implemented to add additional classes to action_menu.
430 * Most Behat functionality for the Moodle App has been removed from core, refer to the documentation in order to upgrade your testing
431 setup: https://moodledev.io/general/app/development/testing/acceptance-testing#upgrading-tests-from-an-older-version
432 * New DML driver methods `$DB->sql_regex_get_word_beginning_boundary_marker` and `$DB->sql_regex_get_word_end_boundary_marker`
433 for managing word boundary markers in a database driver supporting regex syntax when searching.
434 * The plugin_functions cache in core has been made localisable by prefixing the
435 key it uses with the all versions hash, which only changes when there are code
440 * To better detect wrong floats (like, for example, unformatted, using local-dependent separators ones) a number of
441 gradebook functions now have stricter float type checking. All them will require now the "float" being passed to be
442 a correct float value (numeric or string). Usually, that's achieved by using unformat_float() or
443 PARAM_LOCALISEDFLOAT for all the user-entered grades before any processing on them. Functions affected are:
444 - grade_format_gradevalue(), $value param (keeping it as optional/nullable).
445 - grade_format_gradevalue_real(), $value param (keeping it as optional/nullable).
446 - grade_format_gradevalue_percentage(), $value param (keeping it as optional/nullable).
447 - grade_format_gradevalue_letter(), $value param (keeping it as optional/nullable).
448 - grade_floats_different(), $f1 and $f2 params (keeping them as optional/nullable).
449 - grade_floats_equal(), $f1 and $f2 params (keeping them as optional/nullable).
450 * The method action_menu->set_alignment() has been deprecated, please use action_menu->set_menu_left if you need a dropdown
451 to align to the left of the dropdown button.
452 * The $OUTPUT->should_display_main_logo() function has been deprecated and should no longer be used.
453 * New method flexible_table::set_columnsattributes() has been introduced to add column attributes applied in every cell.
454 * New method flexible_table::get_row_cells_html() has been introduced, extracted from flexible_table::get_row_html
455 so it can be overriden individually.
456 * Since Boxnet has been remove from core then boxnet_client() class has been removed from core too.
457 * New navigation classes to mimic the new navigation project. The existing navigation callbacks are still available and
458 will be called. The following behaviour will be the new standard for nodes added via callbacks in Boost and Boost-based themes:
459 - Module nodes added will be appended to the end and will appear within the More menu.
460 - Course nodes added will also be appended and appear within the 'More' menu.
461 * The core/event events have been renamed and now fire native events, in addition to the legacy YUI and jQuery events.
462 The following events have been renamed:
463 - The BLOCK_CONTENT_UPDATED event has been replaced with a new native event in the `core_block/events` AMD module
464 eventTypes.blockContentUpdated.
465 - The EDITOR_CONTENT_RESTORED event has been replaced with a new native event in the `core_editor/events` AMD module
466 eventTypes.editorContentRestored.
467 - The FILTER_CONTENT_UPDATED event has been replaced with a new native event in the `core_filters/events` AMD module
468 eventTypes.filterContentUpdated.
469 - The FORM_FIELD_VALIDATION event has been replaced with a new native event in the `core_form/events` AMD module
470 eventTypes.formFieldValidationFailed.
471 - The FORM_SUBMIT_AJAX event has been replaced with a new native event in the `core_form/events` AMD module
472 eventTypes.formSubmittedByJavascript.
473 * The block template now includues a block-instanceid data attribute.
474 * The core/event::getLegacyEvents() function has been deprecated and should no longer be used.
475 * Typo3 has now been removed. Use native mbstring or iconv functions.
476 * A new index has been added on mdl_user_preferences.name. This upgrade step might take some time on big sites.
477 * The completion_info function display_help_icon() which returned the 'Your progress' help icon has been deprecated and
478 should no longer be used.
479 * The completion_info function print_help_icon() which has been deprecated since Moodle 2.0 should no longer be used.
480 * @babel/polyfill has been removed in favour of corejs@3.
481 * A new parameter $partialrebuild has been added to the rebuild_course_cache to invalidate the cache
482 of the section or module only, not the whole course cache
483 * A new parameter $isbulkupdate has been added to the following functions:
484 - grade_category::update()
485 - grade_category::insert()
486 - grade_grade::update()
487 - grade_grade::insert()
488 - grade_grade::notify_changed()
489 - grade_item::insert()
490 - grade_item::update()
491 - grade_item::update_final_grade()
492 - grade_item::update_raw_grade()
493 - grade_object::update()
494 - grade_object::insert()
495 - grade_outcome::update()
496 - grade_outcome::insert()
497 - grade_scale::update()
498 - grade_scale::insert()
500 - completion_info::inform_grade_changed()
501 - completion_info::update_state()
502 - completion_info::internal_set_data()
503 All functions except completion_info::internal_set_data() are only passing this parameter from very beginning of
504 workflow (like grade report page where bulk grade update is possible) so this parameter is used in
505 completion_info::internal_set_data() to decide if we need to mark completions instantly without waiting for cron.
506 * Following methods now return an int instead of bool:
507 - completion_completion::_save()
508 - completion_completion::mark_enrolled()
509 - completion_completion::mark_inprogress()
510 - completion_completion::mark_complete()
511 which is needed to store id of completion record on successful update which is later beeing used by
512 completion_info::internal_set_data() to reaggregate completions that have been marked for instant course completion.
513 * The following functions have been finally deprecated and can not be used anymore:
515 * The YUI moodle-core-formchangechecker module has been deprecated and replaced with a new AMD module
516 core_form/changechecker.
517 * New method \core_user::awaiting_action() has been introduced to check if the user is fully ready to use the site or
518 whether there is an action (such as filling the missing profile field, changing password or agreeing to the site
520 * The signature of the get_name() function for grade_category and grade_item has been extended. The new parameter allows
521 callers to get the name without escaped characters.
522 * The inplace_editable element constructor now accepts an optional pix_icon parameter to use as it's editing icon when
523 rendered. The default icon for "select" types has also changed to a dropdown caret ("t/expanded").
524 * The inplace_editable Javascript module now emits native events, removing the jQuery dependency from calling code
525 that wants to listen for the events. Backwards compatibility with existing code using jQuery is preserved.
526 * The function message_send() in messagelib.php now returns false if there is an error sending the message to the
527 message processor (MDL-70046).
528 * Moodle 4.0 has major changes to the question bank. Therefore, there are major changes in questionlib.php
529 and the core_question database tables. These are documented in detail in question/upgrade.txt.
530 * The postgres driver now wraps calls to pg_field_type() and caches them in databasemeta to save an invisible internal
531 DB call on every request.
532 * The default type of 'core/toast' messages has been changed to 'information' (callers can still explicitely set the type)
533 * As the message_jabber notification plugin has been moved to the plugins database, the XMPPHP library (aka Jabber) has been
534 completely removed from Moodle core too.
535 * The SWF media player has been completely removed (The Flash Player was deprecated in 2017 and officially discontinued
536 on 31 December 2020).
537 * The display_size function has been improved to add new optional parameters (decimal places,
538 fixed units), to always include a non-breaking space between the number and unit, and to use
539 consistent rounding (always 1 decimal place by default).
540 * The persistent method get() now returns the correct type for each property defined in the persistent class.
541 * The persistent method from_record() now only attempts to load record properties defined in the persistent class.
542 * New persistent set_many() helper for setting multiple properties in single method call.
543 * Require pass grade criteria is now part of core.
544 Refer to upgrade.php to see transitioning from similar plugin criteria to core
545 Refer to completion/upgrade.txt for additional information.
546 * The method enable_plugin() has been added to the core_plugininfo\base class and it has been implemented by all the plugininfo
547 classes extending it. When possible, the enable_plugin() method will store these changes into the config_log table, to let admins
548 check when and who has enabled/disabled plugins.
549 * Final deprecation: The following functions along with associated tests have been removed:
550 - core_grades_external::get_grades
551 - core_grades_external::get_grade_item
552 - report_insights_context_insights
553 * \core\session\manager::init_empty_session() has a new optional parameter $newsid to indicate whether this is a new user session
554 * New html_table attribute "$responsive" which defaults to true. When set to true, tables created via html_writer::table() will be enclosed
555 in a .table-responsive div container which will allow the table to be scrolled horizontally with ease, especially when the table is rendered in smaller viewports.
556 Set to false to prevent the table from being enclosed in the responsive container.
557 * Two new helper functions have been added to lib/datalib.php, for safely preparing SQL ORDER BY statements where user
558 interactions define sort parameters (see the respective docblocks for full details and examples):
559 -get_safe_orderby() - where a single sort parameter is required.
560 -get_safe_orderby_multiple() - where multiple sort parameters are required.
561 * Added the cleanstr mustache template helper to clean strings after loading them from language packs.
562 * The following behat functions have been modified to work with the new navigation
564 - the_add_block_selector_should_contain_block
565 - the_add_block_selector_should_contain_block
566 - go_to_the_current_course_activity_completion_report
567 - i_navigate_to_course_participants
568 - i_go_to_advanced_grading_page
569 - i_navigate_to_in_the_course_gradebook
570 - should_exist_in_current_page_administration
571 - should_not_exist_in_current_page_administration
572 - go_to_main_course_page
573 - select_on_administration_page
574 - find_header_administration_menu
575 - select_from_administration_menu
577 - i_add_a_question_filling_the_form_with
578 * The following behat step has been deprecated
579 - i_select_from_flat_navigation_drawer
580 * The type for the "message" field in the external_warnings() structure has been changed from PARAM_TEXT to PARAM_RAW
581 * A new parameter $displayoptions has been added to the core_renderer::confirm() to allow better customization for confirming page
582 such as the title and strings for continue and cancel buttons.
583 * The method get_enabled_plugin($pluginname) has been added to the core_plugininfo\base class. It has a default implementation for
584 all the plugininfo classes and it can be overwritten when required (like it has been done with filter). This method returns the
585 current value for a pluginname depending on its status (enabled, disabled, other...).
586 * Unit Test coverage defaults have been updated to include some sensible defaults.
587 The default values now include:
595 This default applies both when there is no supplied coverage.php file, and is used to supplement any existing coverage configuration file if one is found.
596 * New method get_unaddable_by_theme_block_types() has been added to block_manager class. It uses the 'unaddableblocks' theme setting
597 value to get the list of blocks that won't be displayed for a theme.
598 * Loggedin / Loggedoff component settings on notification preferences have been merged to a single enabled switch:
599 MESSAGE_DEFAULT_LOGGEDIN and MESSAGE_DEFAULT_LOGGEDOFF are now deprecated, so plugins should be updated if db/messages.php is present and replace
600 MESSAGE_DEFAULT_LOGGEDIN + MESSAGE_DEFAULT_LOGGEDOFF to MESSAGE_DEFAULT_ENABLED. Backward compatibility will take any of both settings as enabled.
601 MESSAGE_DEFAULT_PERMITTED also deprecated.
602 core_message_get_user_notification_preferences and core_message_get_user_message_preferences Webservice are now returning enabled boolean on
603 components > notifications > processors. loggedin and loggedoff are deprecated but present for backward compatibility.
604 * A new parameter $strength of type int is added to method search_for_active_node. This parameter would help us to search for the active nodes based on the
605 $strength passed to it.
606 * A new method get_page() has been added to the settings_navigation class. This method can be used to obtain the
607 moodle_page object associated to the settings navigation.
608 * A new interface, `core\output\named_templatable` has been created to allow renderable classes to define a
609 `get_template_name(\renderer_base): string` function which will inform the default render() function with a template
611 * The parameter $modinfo of the get_data method in completion_info class has been deprecated and is not used anymore.
612 * A new method, get_default_home_page(), has been added to moodlelib to get the default home page to display if current one is not
613 defined or can't be applied.
614 * A new language_menu renderable is created to handle collecting available languages and generating the menu for use in different situations
615 * New primary navigation classes to mimic the primary nav. Consists of the views/primary.php and output/primary.php. The
616 base nodes are added within the views/primary.php while output/primary.php is a renderable that combines the primary
617 view and the lang, user and any custom menu items.
618 - The language menu now resides within the user menu.
619 * New primary and secondary magic getters/setters included in pagelib.php that also initialises the objects
620 * All secondary navigation nodes have a predefined ordering within the relevant context and are defined as a
621 mapping construct within core\navigation\views\secondary. Secondary navigation ordering can be overridden by
622 generating a custom secondary class within a plugin's {plugin}\local\views namespace. This is only applicable to the
623 following plugin types and is automatically loaded:
624 * Module - refer to mod_assign\local\views\secondary for examples and magic_get_secondarynav for calling code
625 * Block - refer to core_block\local\views\secondary for examples and blocklib::get_secondarynav for calling code
626 - Additionally a custom secondary object may be set using the convenient setters in pagelib.php.
627 - Secondary nav nodes can be forced into the 'More' menu using the 'set_force_into_more_menu'. It is advisable to set
628 this in the existing nav callbacks when generating the nodes. Alternately, the corresponding
629 'get_default_{admin/course/module}_more_menu_nodes functions in secondary can be overridded to provide a custom set
630 of node keys to push into the more menu
631 - The secondary navigation can be omitted from a theme/page by setting $PAGE->set_secondary_navigation(false). e.g. admin/search.php and in classic.
632 - Within a single activity course format, the course and module level secondary navigation options are displayed within
633 dropdowns in the secondary navigation bar
634 * New function 'get_overflow_menu_data' introduced in core\navigation\views\secondary to get additional/custom sub navigation
635 to be displayed as a url_select for tertiary navigation.
636 * It is required that the action provided to navigation_node::create be of type moodle_url/action_link. Non conformance
637 results in a debugging message being thrown.
638 * New page lib config '_navigationoverflow' and associated getters/setters to toggle whether the overflow menu is displayed
639 * New functions to explicitly set what tabs should be highlighted on the primary and secondary navigation
640 * Breadcrumbs modified to follow standards defined here https://www.nngroup.com/articles/breadcrumbs/
641 - New navbar class in boost to follow the standards defined above.
642 * Settings cog have been removed and replaced with either secondary and tertiary navigation components
643 * New activity_header class to handle display of common content for plugins.
644 * Handles display of the activity name, completion information and description.
645 * New pagelib.php magic getters to fetch activity_header
646 * New theme level config to govern display of the activity name $THEME->activityheaderconfig['notitle']
647 - Default for boost is to show no activity title.
648 * New page layout level option to handle display within activity header. Options should be defined
649 within 'activityheader' and accept the following array keys:
653 * Convenient functions to set the parameters in the header OR hide them altogether.
654 * Category navigations has been updated with a preference of tertiary navigation components over buttons within the page
655 content and/or context header actions
656 * A new 'My courses' page has been introduced which houses the course overview block
657 * Default blocks for dashboard has been updated. The page will now have the following in the corresponding region:
658 * Calendar, Timeline - Center
659 * Recently accessed courses - Side bar/blocks drawer
660 * Flat navigation classes have been marked for deprecation with the introduction of primary and secondary navigation concepts.
661 * A new method, force_lock_all_blocks(), has been added to the moodle_page class to allow pages to force the value of
662 user_can_edit_blocks() to return false where necessary. This makes it possible to remove block editing on a page
663 from ALL users, including admins, where required on pages with multi region layouts exist, such as "My courses".
664 * Add an early $CFG->session_redis_acquire_lock_warn option
665 * Removed $CFG->conversionattemptlimit setting from config.php. assignfeedback_editpdf\task\convert_submissions task
666 is now replaced with adhoc tasks with standard fail delay approach.
667 * With strftime() being deprecated in PHP 8.1, a new function \core_date::strftime() that can be used as a PHP 8.1-compatible
668 alternative has been introduced.
671 * A new option dontforcesvgdownload has been added to the $options parameter of the send_file() function.
672 Note: This option overrides the forced download of directly accessed SVGs, so should only be used where the calling method is
673 rendering SVGs directly for content created using XSS risk flagged capabilities (such as creating a SCORM activity).
674 This is also not necessary where SVGs are already being safely loaded into <img> tags by Moodle (eg within forum posts).
677 * For security reasons, filelib has been updated so all requests now use emulated redirects.
678 For this reason, manually disabling emulateredirects will no longer have any effect (and will generate a debugging message).
681 * PHPUnit has been upgraded to 9.5 (see MDL-71036 for details).
682 That comes with a few changes:
683 - Breaking: All the changes that were deprecated with PHPUnit 8.5
684 are now removed (see the 3.10 section below).
685 - Breaking: assertContains() now performs stricter comparison (like assertSame()
686 does). New assertContainsEquals() has been created to provide the old
688 - Deprecation: A number of file-related assertions have been deprecated, will
689 be removed with PHPUnit 10. Alternatives for all them have been created:
690 - assertNotIsReadable() -> assertIsNotReadable()
691 - assertNotIsWritable() -> assertIsNotWritable()
692 - assertDirectoryNotExists() -> assertDirectoryDoesNotExist()
693 - assertDirectoryNotIsReadable()-> assertDirectoryIsNotReadable()
694 - assertDirectoryNotIsWritable()-> assertDirectoryIsNotWritable()
695 - assertFileNotExists() -> assertFileDoesNotExist()
696 - assertFileNotIsReadable() -> assertFileIsNotReadable()
697 - assertFileNotIsWritable() -> assertFileIsNotWritable()
698 - Deprecation: Regexp-related assertions have been deprecated, will be
699 removed with PHPUnit 10. Alternatives for all them have been created:
700 - assertRegExp() -> assertMatchesRegularExpression()
701 - assertNotRegExp() -> assertDoesNotMatchRegularExpression()
702 - Deprecation: The expectException() for Notice, Warning, Deprecation and
703 Error is deprecated, will be removed with PHPUnit 10. New expectations
704 have been created to better define the expectation:
705 - expectDeprecation() for E_DEPRECATED and E_USER_DEPRECATED.
706 - expectNotice() for E_NOTICE, E_USER_NOTICE, and E_STRICT.
707 - expectWarning() for E_WARNING and E_USER_WARNING.
708 - expectError() for everything else.
709 - Deprecation: The Mock->at() matcher has been deprecated and will be
710 removed with PHPUnit 10. Switch to better, more deterministic and clearer
711 matchers is recommended (->once(), ->exactly(), ->never()...).
712 - Deprecation: The Mock->setMethods() method has been *silently* deprecated
713 and will be removed in the future. Change uses to the new Mock->onlyMethods()
714 alternative. Also, it doesn't accept "null" anymore, new default must
716 - Mostly internal: With the raise to PHP 7.3 as lower version supported,
717 various internal bits perform now stricter type checking in params and
718 return values. If your tests have own-created comparators, assertions...
719 they may need to be adjusted.
720 - Mostly internal: The phpunit.xml schema has changed, basically removing
721 the old <filter> section and replacing it with a new, less confusing
722 <coverage> section. Also the elements within them have been changed:
723 - <whitelist> has been replaced by <include>.
724 - <exclude> is not a child of <whitelist> anymore, but of <coverage>.
725 Note that this only will affect if you've custom phpunit.xml files
726 instead of using the automatically generated ones by Moodle.
727 - Deprecation: Related to the previous point, the $whitelistxxx properties
728 used by the coverage.php files have been deprecated (will continue
729 working until Moodle 4.3) to follow the same pattern:
730 - whitelistfolders -> includelistfolders
731 - whitelistfiles -> includelistfiles
732 - Internal: Custom autoloaders are deprecated and will be removed with
733 PHPUnit 10. Hence we have removed our one already.
734 Note that it was not useful since PHPUnit 8.5, where the ability
735 to run tests by class name was removed.
736 - Warning: Because of some new restrictions about how test files and
737 test classes must be named (that Moodle haven't followed ever) it's not
738 possible to run individual test files any more. Use any of the alternative
739 execution methods (filter, suite, config) to specify which tests
740 you want to run. This will be hopefully fixed in MDL-71049
741 once it has been agreed which the best way to proceed is.
742 * The horde library has been updated to version 5.2.23.
743 * New optional parameter $extracontent for print_collapsible_region_start(). This allows developers to add interactive HTML elements
744 (e.g. a help icon) after the collapsible region's toggle link.
745 * Final deprecation i_dock_block() in behat_deprecated.php
746 * Final deprecation of get_courses_page. Function has been removed and core_course_category::get_courses() should be
748 * New encryption API in \core\encryption allows secure encryption and decryption of data. By
749 default the key is stored in moodledata but admins can configure a different, more secure
750 location in config.php if required. To get the best possible security for this feature, we
751 recommend enabling the Sodium PHP extension.
752 The OpenSSL alternative for this API, used when Sodium is not available, is considered deprecated
753 at all effects, and will be removed in Moodle 4.2. See MDL-71421 for more information.
754 * Behat timeout constants behat_base::TIMEOUT, EXTENDED_TIMEOUT, and REDUCED_TIMEOUT, which were deprecated in 3.7, have been removed.
755 * \core_table\local\filter\filterset::JOINTYPE_DEFAULT is being changed from 1 (ANY) to 2 (ALL). Filterset implementations
756 can override the default filterset join type by overriding \core_table\local\filter\filterset::get_join_type() instead.
757 * HTMLPurifier has been upgraded to the latest version - 4.13.0
758 * Markdown lib has been upgraded to the latest version - 1.9.0
759 * The minify lib has been upgraded to 1.3.63 and pathconvertor to 1.1.3
760 * A new optional parameter `$sort` has been added to all `$context->get_capabilities()` methods to be able to define order of
761 returned capability array.
762 * Spout has been upgraded to the latest version - 3.1.0
763 * emoji-data has been upgraded to 6.0.0.
764 * The final deprecation of /message/defaultoutputs.php file and admin_page_defaultmessageoutputs.
765 All their settings moved to admin/message.php (see MDL-64495). Please use admin_page_managemessageoutputs class instead.
766 * Behat now supports date selection from the date form element. Examples:
767 - I set the field "<field_string>" to "##15 March 2021##"
768 - I set the field "<field_string>" to "##first day of January last year##"
769 * Behat now supports date and time selection from the datetime form element. Examples:
770 - I set the field "<field_string>" to "##15 March 2021 08:15##"
771 - I set the field "<field_string>" to "##first day of January last year noon##"
772 * New DML driver method `$DB->sql_group_concat` for performing group concatenation of a field within a SQL query
773 * Added new class, AMD modules and WS that allow displaying forms in modal popups or load and submit in AJAX requests.
774 See https://docs.moodle.org/dev/Modal_and_AJAX_forms for more details.
775 * New base class for defining an activity's custom completion requirements: \core_completion\activity_custom_completion.
776 Activity module plugins that define custom completion conditions should implement a mod_[modname]\completion\custom_completion
777 subclass and the following methods:
778 - get_state(): Provides the completion state for a given custom completion rule.
779 - get_defined_custom_rules(): Returns an array of the activity module's custom completion rules.
780 e.g. ['completionsubmit']
781 - get_custom_rule_descriptions(): Returns an associative array with values containing the user-facing textual description
782 of the custom completion rules (which serve as the keys to these values).
783 e.g. ['completionsubmit' => 'Must submit']
784 - get_sort_order(): Returns an array listing the order the activity module's completion rules should be displayed to the user,
785 including both custom completion and relevant core completion rules
786 e.g. ['completionview', 'completionsubmit', 'completionusegrade']
787 * Admin setting admin_setting_configmulticheckbox now supports lazy-loading the options list by
788 supplying a callback function instead of an array of options.
789 * A new core API class \core_user\fields provides ways to get lists of user fields, and SQL related to
790 those fields. This replaces existing functions get_extra_user_fields(), get_extra_user_fields_sql(),
791 get_user_field_name(), get_all_user_name_fields(), and user_picture::fields(), which have all been
793 * Allow plugins to augment the curl security helper via callback. The plugin's function has to be defined as
794 plugintype_pluginname_curl_security_helper in pluginname/lib.php file and the function should return a plugin's security
796 * The behat transformation 'string time to timestamp' no longer supports datetime format. If provided, the format must
797 be strftime compatible. Example:
798 - I should see "##tomorrow noon##%A, %d %B %Y, %I:%M %p##"
799 * External functions implementation classes should use 'execute' as the method name, in which case the
800 'methodname' property should not be specified in db/services.php file.
801 * The core_grades_create_gradecategory webservice has been deprecated in favour of core_grades_create_gradecategories, which is
802 functionally identical but allows for parallel gradecategory creations by supplying a data array to the webservice.
803 * The signature of the get_context_name() function in the abstract class context and all extending classes (such as context_course)
804 has been extended. The new parameter allows the to get the name without escaped characters.
805 * The signature of the question_category_options() has been extended. The new parameter allows the to get the categories name
806 in the returned array without escaped characters.
807 * The \core\hub\site_registration_form::add_select_with_email() method has been deprecated in favour of
808 \core\hub\site_registration_form::add_checkbox_with_email().
811 * PHPUnit has been upgraded to 8.5. That comes with a few changes:
812 - Breaking change: All the "template methods" (setUp(), tearDown()...) now require to return void. This implies
813 that the minimum version of PHP able to run tests will be PHP 7.1
814 - A good number of assertions have been deprecated with this version
815 and will be removed in a future one. In core all cases have been removed
816 (so it's deprecation-warnings free). It's recommended to perform the
817 switch to their new counterparts ASAP:
818 - assertInternalType() has been deprecated. Use the assertIsXXX() methods instead.
819 - assertArraySubset() has been deprecated. Use looping + assertArrayHasKey() or similar.
820 - @expectedExceptionXXX annotations have been deprecated. Use the expectExceptionXXX()
821 methods instead (and put them exactly before the line that is expected to throw the exception).
822 - assertAttributeXXX() have been deprecated. If testing public attributes use normal assertions. If
823 testing non-public attributes... you're doing something wrong :-)
824 - assertContains() to find substrings on strings has been deprecated. Use assertStringContainsString() instead.
825 (note that there are "IgnoringCase()" variants to perform case-insensitive matching.
826 - assertEquals() extra params have been deprecated and new assertions for them created:
827 - delta => use assertEqualsWithDelta()
828 - canonicalize => use assertEqualsCanonicalizing()
829 - ignoreCase => use assertEqualsIgnoringCase()
830 - maxDepth => removed without replacement.
831 - The custom printer that was used to show how to rerun a failure has been removed, it was old and "hacky"
832 solution, for more information about how to run tests, see the docs, there are plenty of options.
833 - phpunit/dbunit is not available any more and it has been replaced by a lightweight phpunit_dataset class, able to
834 load XML/CSV and PHP arrays, send the to database and return rows to calling code (in tests). That implies the
835 follwoing changes in the advanced_testcase class:
836 - createFlatXMLDataSet() has been removed. No uses in core, uses can switch to createXMLDataSet() (read below).
837 - createXMLDataSet() has been deprecated. Use dataset_from_files() instead.
838 - createCsvDataSet() has been deprecated. Use dataset_from_files() instead.
839 - createArrayDataSet() has been deprecated. This method was using the phpunit_ArrayDataSet class
840 that has been also removed from core. Use dataset_from_array() instead.
841 - loadDataSet() has been deprecated. Use phpunit_dataset->to_database() instead.
842 - All the previous uses of phpunit/dbunit methods like Dataset:getRows(), Dataset::getRowCount()
843 must be replaced by the new phpunit_dataset->get_rows() method.
844 * Retains the source course id when a course is copied from another course on the same site.
845 * Added function setScrollable in core/modal. This function can be used to set the modal's body to be scrollable or not
846 when the modal's height exceeds the browser's height. This is also supported in core/modal_factory through the
847 'scrollable' config parameter which can be set to either true or false. If not explicitly defined, the default value
848 of 'scrollable' is true.
849 * The `$CFG->behat_retart_browser_after` configuration setting has been removed.
850 The browser session is now restarted between all tests.
851 * add_to_log() has been through final deprecation, please rewrite your code to the new events API.
852 * The following functions have been finally deprecated and can not be used anymore:
854 - calendar_get_all_allowed_types
855 - groups_get_all_groups_for_courses
860 - events_get_handlers
861 - get_roles_on_exact_context
862 - get_roles_with_assignment_on_context
863 - message_add_contact
864 - message_remove_contact
865 - message_unblock_contact
866 - message_block_contact
867 - message_get_contact
870 - get_legacy_eventname
871 - get_legacy_eventdata
872 * The following renamed classes have been completely removed:
873 - course_in_list (now: core_course_list_element)
874 - coursecat (now: core_course_category)
875 * The form element 'htmleditor', which was deprecated in 3.6, has been removed.
876 * The `core_output_load_fontawesome_icon_map` web service has been deprecated and replaced by
877 `core_output_load_fontawesome_icon_system_map` which takes the name of the theme to generate the icon system map for.
878 * A new parameter `$rolenamedisplay` has been added to `get_viewable_roles()` and `get_switchable_roles` to define how role names
880 * The class coursecat_sortable_records has been removed.
881 * Admin setting admin_setting_configselect now supports lazy-loading the options list by supplying
882 a callback function instead of an array of options.
883 * Admin setting admin_setting_configselect now supports validating the selection by supplying a
885 * The task system has new functions adhoc_task_starting() and scheduled_task_starting() which must
886 be called before executing a task, and a new function \core\task\manager::get_running_tasks()
887 returns information about currently-running tasks.
888 * New library function rename_to_unused_name() to rename a file within its current location.
889 * Constant \core_h5p\file_storage::EDITOR_FILEAREA has been deprecated
890 because it's not required any more.

892 * The php-enum library has been added to Moodle core in /lib/php-enum.
893 * The http-message library has been added to Moodle core in /lib/http-message.
894 * Methods `filetypes_util::is_whitelisted()` and `filetypes_util::get_not_whitelisted()` have been deprecated and
895 renamed to `is_listed()` and `get_not_listed()` respectively.
896 * Method `mustache_helper_collection::strip_blacklisted_helpers()` has been deprecated and renamed to
897 `strip_disallowed_helpers()`.
898 * A new admin externalpage type `\core_admin\local\externalpage\accesscallback` for use in plugin settings is available that allows
899 a callback to be provided to determine whether page can be accessed.
900 * New setting $CFG->localrequestdir overrides which defaults to sys_get_temp_dir()
901 * Function redirect() now emits a line of backtrace into the X-Redirect-By header when debugging is on

914 * Old Safe Exam Browser quiz access rule (quizaccess_safebrowser) replaced by new Safe Exam Browser access rule (quizaccess_seb).
915 Experimental setting enablesafebrowserintegration was deleted.
916 * New CFPropertyList library has been added to Moodle core in /lib/plist.
917 * behat_data_generators::the_following_exist() has been removed, please use
918 behat_data_generators::the_following_entities_exist() instead. See MDL-67691 for more info.
919 * admin/tool/task/cli/adhoc_task.php now observers the concurrency limits.
920 If you want to get the previous (unlimited) behavior, use the --ignorelimits switch).
921 * Removed the following deprecated functions:
923 - question_is_only_toplevel_category_in_context
924 * format_float() now accepts a special value (-1) as the $decimalpoints parameter
925 which means auto-detecting number of decimal points.
926 * plagiarism_save_form_elements() has been deprecated. Please use {plugin name}_coursemodule_edit_post_actions() instead.
927 * plagiarism_get_form_elements_module() has been deprecated. Please use {plugin name}_coursemodule_standard_elements() instead.
928 * Changed default sessiontimeout to 8 hours to cover most normal working days
929 * Plugins can now explicitly declare supported and incompatible Moodle versions in version.php
930 - $plugin->supported = [37,39];
931 supported takes an array of ascending numbers, that correspond to a range of branch numbers of supported versions, inclusive.
932 Moodle versions that are outside of this range will produce a message notifying at install time, but will allow for installation.
933 - $plugin->incompatible = 36;
934 incompatible takes a single int corresponding to the first incompatible branch. Any Moodle versions including and
935 above this will be prevented from installing the plugin, and a message will be given when attempting installation.
936 * Added the <component>_bulk_user_actions() callback which returns a list of custom action_links objects
937 * Add 'required' admin flag for mod forms allows elements to be toggled between being required or not in admin settings.
938 - In mod settings, along with lock, advanced flags, the required flag can now be set with $setting->set_required_flag_options().
939 The name of the admin setting must be exactly the same as the mod_form element.
940 - Currently supported by:
943 * Added a native MySQL / MariaDB lock implementation
944 * The database drivers (moodle_database and subclasses) don't need to implement get_columns() anymore.
945 They have to implement fetch_columns instead.
946 * Added function cleanup_after_drop to the database_manager class to take care of all the cleanups that need to be done after a table is dropped.
947 * The 'xxxx_check_password_policy' callback now only fires if $CFG->passwordpolicy is true
948 * grade_item::update_final_grade() can now take an optional parameter to set the grade->timemodified. If not present the current time will carry on being used.
949 * lib/outputrequirementslib::get_jsrev now is public, it can be called from other classes.
950 * H5P libraries have been moved from /lib/h5p to h5p/h5plib as an h5plib plugintype.
951 * mdn-polyfills has been renamed to polyfills. The reason there is no polyfill from the MDN is
952 because there is no example polyfills on the MDN for this functionality.
953 * AJAX pages can be called without requiring a session lock if they set READ_ONLY_SESSION to true, eg.
954 define('READ_ONLY_SESSION', true); Note - this also requires $CFG->enable_read_only_sessions to be set to true.
955 * External functions can be called without requiring a session lock if they define 'readonlysession' => true in
956 db/services.php. Note - this also requires $CFG->enable_read_only_sessions to be set to true.
957 * database_manager::check_database_schema() now checks for missing and extra indexes.
958 * Implement a more direct xsendfile_file() method for an alternative_file_system_class
959 * A new `dynamic` table interface has been defined, which allows any `flexible_table` to be converted into a table which
960 is updatable via ajax calls. See MDL-68495 and `\core_table\dynamic` for further information.
961 * The core/notification module has been updated to use AMD modals for its confirmation and alert dialogues.
962 The confirmation dialogue no longer has a configurable "No" button as per similar changes in MDL-59759.
963 This set of confirmation modals was unintentionally missed from that deprecation process.
964 * The download_as_dataformat() method has been deprecated. Please use \core\dataformat::download_data() instead
965 * The following functions have been updated to support passing in an array of group IDs (but still support passing in a single ID):
966 * groups_get_members_join()
967 * groups_get_members_ids_sql()
968 * Additional parameters were added to core_get_user_dates:
969 - type: specifies the calendar type. Optional, defaults to Gregorian.
970 - fixday: Whether to remove leading zero for day. Optional, defaults to 1.
971 - fixhour: Whether to remove leading zero for hour. Optional, defaults to 1.
972 * Legacy cron has been deprecated and will be removed in Moodle 4.1. This includes the functions:
973 - cron_execute_plugin_type()
974 - cron_bc_hack_plugin_functions()
975 Please, use the Task API instead: https://moodledev.io/docs/apis/subsystems/task
976 * Introduce new hooks for plugin developers:
977 - <component>_can_course_category_delete($category)
978 - <component>_can_course_category_delete_move($category, $newcategory)
979 These hooks allow plugin developers greater control over category deletion. Plugin can return false in those
980 functions if category deletion or deletion with content move to the new parent category is not permitted.
981 Both $category and $newcategory params are instances of core_course_category class.
982 - <component>_pre_course_category_delete_move($category, $newcategory)
983 This hook is expanding functionality of existing <component>_pre_course_category_delete hook and allow plugin developers
984 to execute code prior to category deletion when its content is moved to another category.
985 Both $category and $newcategory params are instances of core_course_category class.
986 - <component>_get_course_category_contents($category)
987 This hook allow plugin developers to add information that is displayed on category deletion form. Function should
988 return string, which will be added to the list of category contents shown on the form. $category param is an instance
989 of core_course_category class.
990 * Data generator create_user in both unittests and behat now validates user fields and triggers user_created event
993 * Add CLI option to notify all cron tasks to stop: admin/cli/cron.php --stop
994 * The rotate_image function has been added to the stored_file class (MDL-63349)
995 * The yui checknet module is removed. Call \core\session\manager::keepalive instead.
996 * The generate_uuid() function has been deprecated. Please use \core\uuid::generate() instead.
997 * Remove lib/pear/auth/RADIUS.php (MDL-65746)
998 * Core components are now defined in /lib/components.json instead of coded into /lib/classes/component.php
999 * Subplugins should now be defined using /db/subplugins.json instead of /db/subplugins.php
1000 * The following functions have been finally deprecated and can not be used anymore:
1005 * verify_https_required()
1006 * Remove duplicate font-awesome SCSS, Please see /theme/boost/scss/fontawesome for usage (MDL-65936)
1007 * Remove lib/pear/Crypt/CHAP.php (MDL-65747)
1008 * New output component available: \core\output\checkbox_toggleall
1009 - This allows developers to easily output groups of checkboxes that can be toggled by master controls in the form of a checkbox or
1010 a button. Action elements which perform actions on the selected checkboxes can also be enabled/disabled depending on whether
1011 at least a single checkbox item is selected or not.
1012 * Final deprecation (removal) of the core/modal_confirm dialogue.
1013 * Upgrade scssphp to v1.0.2, This involves renaming classes from Leafo => ScssPhp as the repo has changed.
1014 * Implement supports_xsendfile() method and allow support for xsendfile in alternative_file_system_class
1015 independently of local files (MDL-66304).
1016 * The methods get_local_path_from_storedfile and get_remote_path_from_storedfile in lib/filestore/file_system.php
1017 are now public. If you are overriding these then you will need to change your methods to public in your class.
1018 * It is now possible to use sub-directories for AMD modules.
1019 The standard rules for Level 2 namespaces also apply to AMD modules.
1020 The sub-directory used must be either an valid component, or placed inside a 'local' directory to ensure that it does not conflict with other components.
1022 The following are all valid module names and locations in your plugin:
1023 mod_forum/view: mod/forum/amd/src/view.js
1024 mod_forum/local/views/post: mod/forum/amd/src/local/views/post
1025 mod_forum/form/checkbox-toggle: mod/forum/amd/src/form/checkbox-toggle.js
1027 The following are all invalid module names and locations in your plugin:
1028 mod_forum/views/post: mod/forum/amd/src/views/post
1029 * The 'xxxx_check_password_policy' method now has an extra parameter: $user. It contains the user object to perform password
1030 validation against and defaults to null (so, no user needed) if not provided.
1031 * It is now possible to use sub-directories when creating mustache templates.
1032 The standard rules for Level 2 namespaces also apply to templates.
1033 The sub-directory used must be either an valid component, or placed inside a 'local' directory to ensure that it does not conflict with other components.
1035 The following are all valid template names and locations in your plugin:
1036 mod_forum/forum_post: mod/forum/templates/forum_post.mustache
1037 mod_forum/local/post/user: mod/forum/templates/local/post/user.mustache
1038 mod_forum/form/checkbox_toggle: mod/forum/templates/form/checkbox_toggle.mustache
1040 The following are _invalid_ template names and locations:
1041 mod_forum/post/user: mod/forum/templates/local/post/user.mustache
1042 * Following behat steps have been removed from core:
1043 - I go to "<gradepath_string>" in the course gradebook
1044 * A new admin setting widget 'core_admin\local\settings\filesize' is added.
1045 * Core capabilities 'moodle/community:add' and 'moodle/community:download' have been removed from core as part of Moodle.net sunsetting.
1046 * As part of Moodle.net sunsetting process the following hub api functions have been deprecated:
1048 - unregister_courses
1051 - download_course_backup
1052 - upload_course_backup
1053 * A new setting 'Cache templates' was added (see MDL-66367). This setting determines if templates are cached or not.
1054 This setting can be set via the UI or by defining $CFG->cachetemplates in your config.php file. It is a boolean
1055 and should be set to either false or true. Developers will probably want to set this to false.
1056 * The core_enrol_edit_user_enrolment webservice has been deprecated. Please use core_enrol_submit_user_enrolment_form instead.
1057 * \single_button constructor has a new attributes param to add attributes to the button HTML tag.
1058 * Improved url matching behaviour for profiled urls and excluded urls
1059 * Attempting to use xsendfile via the 3rd param of readstring_accel() is now ignored.
1060 * New H5P libraries have been added to Moodle core in /lib/h5p.
1061 * New H5P core subsystem have been added.
1062 * Introduced new callback for plugin developers '<component>_get_path_from_pluginfile($filearea, $args)': This will return
1063 the itemid and filepath for the filearea and path defined in $args. It has been added in order to get the correct itemid and
1064 filepath because some components, such as mod_page or mod_resource, add the revision to the URL where the itemid should be placed
1065 (to prevent caching problems), but then they don't store it in database.
1066 * New utility function \core_form\util::form_download_complete should be called if your code sends
1067 a file with Content-Disposition: Attachment in response to a Moodle form submit button (to ensure
1068 that disabled submit buttons get re-enabled in that case). It is automatically called by the
1069 filelib.php send_xx functions.
1070 * If you have a form which sends a file in response to a Moodle form submit button, but you cannot
1071 call the above function because the file is sent by a third party library, then you should add
1072 the attribute data-double-submit-protection="off" to your form.
1076 * Nodes in the navigation api can have labels for each group. See set/get_collectionlabel().
1077 * The method core_user::is_real_user() now returns false for userid = 0 parameter
1078 * 'mform1' dependencies (in themes, js...) will stop working because a randomly generated string has been added to the id
1079 attribute on forms to avoid collisions in forms loaded in AJAX requests.
1080 * A new method to allow queueing or rescheduling of an existing scheduled task was added. This allows an existing task
1081 to be updated or queued as required. This new functionality can be found in \core\task\manager::reschedule_or_queue_adhoc_task.
1082 * Icons are displayed for screen readers unless they have empty alt text (aria-hidden). Do not provide an icon with alt text immediately beside an element with exactly the same text.
1083 * admin_settingpage has a new function hide_if(), modeled after the same functionality in the forms library. This allows admin settings to be dynamically hidden based on the values of other settings.
1084 * The \core_rating provider's get_sql_join function now accepts an optional $innerjoin parameter.
1085 It is recommended that privacy providers using this function call rewrite any long query into a number of separate
1086 calls to add_from_sql for improved performance, and that the new argument is used.
1087 This will allow queries to remain backwards-compatible with older versions of Moodle but will have significantly better performance in version supporting the innerjoin parameter.
1088 * /message/defaultoutputs.php file and admin_page_defaultmessageoutputs class have been deprecated
1089 and all their settings moved to admin/message.php (see MDL-64495). Please use admin_page_managemessageoutputs class instead.
1090 * A new parameter $lang has been added to mustache_template_source_loader->load_with_dependencies() method
1091 so it is possible for Mustache to request string in a specific language.
1092 * Behat timeout constants behat_base::TIMEOUT, EXTENDED_TIMEOUT, and REDUCED_TIMEOUT have been
1093 deprecated. Please instead use the functions behat_base::get_timeout(), get_extended_timeout(),
1094 and get_reduced_timeout(). These allow for timeouts to be increased by a setting in config.php.
1095 * The $draftitemid parameter of file_save_draft_area_files() function now supports the constant IGNORE_FILE_MERGE:
1096 When the parameter is set to that constant, the function won't process file merging, keeping the original state of the file area.
1097 Notice also than when $text is set, pluginfile rewrite won't be processed so the text will not be modified.
1098 * Introduced new callback for plugin developers '<component>_pre_processor_message_send($procname, $proceventdata)':
1099 This will allow any plugin to manipulate messages or notifications before they are sent by a processor (email, mobile...)
1100 * New capability 'moodle/category:viewcourselist' in category context that controls whether user is able to browse list of courses
1101 in this category. To work with list of courses use API methods in core_course_category and also 'course' form element.
1102 * It is possible to pass additional conditions to get_courses_search();
1103 core_course_category::search_courses() now allows to search only among courses with completion enabled.
1104 * Add support for a new xxx_after_require_login callback
1105 * A new conversation type has been created for self-conversations. During the upgrading process:
1106 - Firstly, the existing self-conversations will be starred and migrated to the new type, removing the duplicated members in the
1107 message_conversation_members table.
1108 - Secondly, the legacy self conversations will be migrated from the legacy 'message_read' table. They will be created using the
1109 new conversation type and will be favourited.
1110 - Finally, the self-conversations for all remaining users without them will be created and starred.
1111 Besides, from now, a self-conversation will be created and starred by default to all the new users (even when $CFG->messaging
1113 * New optional parameter $throwexception for \get_complete_user_data(). If true, an exception will be thrown when there's no
1114 matching record found or when there are multiple records found for the given field value. If false, it will simply return false.
1115 Defaults to false when not set.
1116 * Exposed submit button to allow custom styling (via customclassoverride variable) which can override btn-primary/btn-secondary classes
1117 * `$includetoken` parameter type has been changed. Now supports:
1118 boolean: False indicates to not include the token, true indicates to generate a token for the current user ($USER).
1119 integer: Indicates to generate a token for the user whose id is the integer value.
1120 * The following functions have been updated to support the new usage:
1121 - make_pluginfile_url
1122 - file_rewrite_pluginfile_urls
1123 * New mform element 'float' handles localised floating point numbers.
1127 * A new token-based version of pluginfile.php has been added which can be used for out-of-session file serving by
1128 setting the `$includetoken` parameter to true on the `moodle_url::make_pluginfile_url()`, and
1129 `moodle_url::make_file_url()` functions.
1130 * The following picture functions have been updated to support use of the new token-based file serving:
1131 - print_group_picture
1132 - get_group_picture_url
1133 * The `user_picture` class has a new public `$includetoken` property which can be set to make use of the new token-based
1135 * Custom AJAX handlers for the form autocomplete fields can now optionally return string in their processResults()
1136 callback. If a string is returned, it is displayed instead of the list of suggested items. This can be used, for
1137 example, to inform the user that there are too many items matching the current search criteria.
1138 * The form element 'htmleditor' has been deprecated. Please use the 'editor' element instead.
1139 * The print_textarea() function has been deprecated. Please use $OUTPUT->print_textarea() instead.
1140 * The following functions have been finally deprecated and can not be used any more:
1141 - external_function_info()
1142 - core_renderer::update_module_button()
1146 - events_is_registered()
1148 - events_pending_count()
1149 - events_process_queued_handler()
1150 - events_queue_handler()
1151 - events_trigger_legacy()
1152 - events_update_definition()
1154 - course_get_cm_rename_action()
1155 - course_scale_used()
1157 - clam_message_admins()
1158 - get_clam_error_code()
1166 - build_logs_array()
1167 - get_logs_usercourse()
1168 - get_logs_userday()
1170 - prevent_form_autofill_password()
1171 - prefixed_tablenode_transformations()
1172 - core_media_renderer
1174 * Following api's have been removed in behat_config_manager, please use behat_config_util instead.
1175 - get_features_with_tags()
1176 - get_components_steps_definitions()
1177 - get_config_file_contents()
1178 - merge_behat_config()
1179 - get_behat_profile()
1180 - profile_guided_allocate()
1183 - get_behat_tests_path()
1184 * Following behat steps have been removed from core:
1185 - I set the field "<field_string>" to multiline
1186 - I follow "<link_string>"" in the open menu
1187 * The following behat steps have been deprecated, please do not use these step definitions any more:
1188 - behat_navigation.php: i_navigate_to_node_in()
1189 - theme/boost/tests/behat/behat_theme_boost_behat_navigation.php: i_navigate_to_node_in()
1190 Use one of the following steps instead:
1191 - I navigate to "PATH > ITEM" in current page administration
1192 - I navigate to "PATH > ITEM" in site administration
1193 - I navigate to course participants
1194 - I navigate to "TAB1 > TAB2" in the course gradebook
1195 If some items are not available without Navigation block at all, one can use combination of:
1196 - I add the "Navigation" block if not present
1197 - I click on "LINK" "link" in the "Navigation" "block"
1198 * The core\session\util class has been removed. This contained one function only used by the memcached class which has
1199 been moved there instead (connection_string_to_memcache_servers).
1200 * Removed the lib/password_compat/lib/password.php file.
1201 * The eventslib.php file has been deleted and its functions have been moved to deprecatedlib.php. The affected functions are:
1202 - events_get_cached()
1203 - events_uninstall()
1206 - events_get_handlers()
1207 * coursecat::get() now has optional $user parameter.
1208 * coursecat::is_uservisible() now has optional $user parameter.
1209 * Removed the lib/form/submitlink.php element which was deprecated in 3.2.
1210 * The user_selector classes do not support custom list of extra identity fields any more. They obey the configured user
1211 policy and respect the privacy setting made by site administrators. The list of user identifiers should never be
1212 hard-coded. Instead, the setting $CFG->showuseridentity should be always respected, which has always been the default
1213 behaviour (MDL-59847).
1214 * The function message_send() in messagelib.php will now only take the object \core\message\message as a parameter.
1215 * The method message_sent::create_from_ids() parameter courseid is now required. A debugging
1216 message was previously displayed, and the SITEID was used, when not provided.
1217 * The method \core\message\manager::send_message() now only takes the object \core\message\message as the first parameter.
1218 * Following functions have been deprecated, please use get_roles_used_in_context.
1219 - get_roles_on_exact_context()
1220 - get_roles_with_assignment_on_context()
1221 * New functions to support the merging of user draft areas from the interface; see MDL-45170 for details:
1222 - file_copy_file_to_file_area()
1223 - file_merge_draft_areas()
1224 - file_replace_file_area_in_text()
1225 - extract_draft_file_urls_from_text()
1226 * Class coursecat is now alias to autoloaded class core_course_category, course_in_list is an alias to
1227 core_course_list_element, class coursecat_sortable_records is deprecated without replacement.
1228 * \core_user_external::create_users() and \core_user_external::update_users() can now accept more user profile fields so user
1229 creation/update via web service can now be very similar to the edit profile page's functionality. The new fields that have been
1244 * New function mark_user_dirty() must be called after changing data that gets cached in user sessions. Examples:
1245 - Assigning roles to users.
1246 - Unassigning roles from users.
1247 - Enrolling users into courses.
1248 - Unenrolling users from courses.
1249 * New optional parameter $context for the groups_get_members_join() function and ability to filter users that are not members of
1250 any group. Besides, groups_get_members_ids_sql, get_enrolled_sql and get_enrolled_users now accepts -1 (USERSWITHOUTGROUP) for
1252 * Added $CFG->conversionattemptlimit setting to config.php allowing a maximum number of retries before giving up conversion
1253 of a given document by the assignfeedback_editpdf\task\convert_submissions task. Default value: 3.
1254 * The following events have been deprecated and should not be used any more:
1255 - message_contact_blocked
1256 - message_contact_unblocked
1257 The reason for this is because you can now block/unblock users without them necessarily being a contact. These events
1258 have been replaced with message_user_blocked and message_user_unblocked respectively.
1259 * The event message_deleted has been changed, it no longer records the value of the 'useridto' due to
1260 the introduction of group messaging. Please, if you have any observers or are triggering this event
1261 in your code you will have to make some changes!
1262 * The gradebook now supports the ability to accept files as feedback. This can be achieved by adding
1263 'feedbackfiles' to the $grades parameter passed to grade_update().
1265 $grades['feedbackfiles'] = [
1267 'component' => 'mod_xyz',
1268 'filearea' => 'mod_xyz_feedback',
1271 These files will be then copied to the gradebook file area.
1272 * Allow users to choose who can message them for privacy reasons, with a 'growing circle of contactability':
1273 - Added $CFG->messagingallusers, for enabling messaging to all site users. Default value: 0.
1274 When $CFG->messagingallusers = false users can choose being contacted by only contacts or contacts and users sharing a course with them.
1275 In that case, the default user preference is MESSAGE_PRIVACY_COURSEMEMBER (users sharing a course).
1276 When $CFG->messagingallusers = true users have a new option for the privacy messaging preferences: "Anyone on the site". In that case,
1277 the default user preference is MESSAGE_PRIVACY_SITE (all site users).
1278 - Added $CFG->keepmessagingallusersenabled setting to config.php to force enabling $CFG->messagingallusers during the upgrading process.
1280 When $CFG->keepmessagingallusersenabled is set to true, $CFG->messagingallusers will be also set to true to enable messaging site users.
1281 However, when it is empty, $CFG->messagingallusers will be disabled during the upgrading process, so the users will only be able to
1282 message contacts and users sharing a course with them.
1283 * There has been interface and functional changes to admin_apply_default_settings() (/lib/adminlib.php). The function now takes two
1284 additional optional parameters, $admindefaultsettings and $settingsoutput. It also has a return value $settingsoutput.
1285 The function now does not need to be called twice to ensure all default settings are set. Instead the function calls itself recursively
1286 until all settings have been set. The additional parameters are used recursively and shouldn't be need to be explicitly passed in when calling
1287 the function from other parts of Moodle.
1288 The return value: $settingsoutput is an array of setting names and the values that were set by the function.
1289 * Webservices no longer update the lastaccess time for a user in a course. Call core_course_view_course() manually if needed.
1290 * A new field has been added to the context table. Please ensure that any contxt preloading uses get_preload_record_columns_sql or get_preload_record_columns to fetch the list of columns.
1294 * There is a new privacy API that every subsystem and plugin has to implement so that the site can become GDPR
1295 compliant. Plugins use this API to report what information they store or process regarding users, and provide ability
1296 to export and delete personal data. See https://moodledev.io/docs/apis/subsystems/privacy for guidelines on how to implement the
1297 privacy API in your plugin.
1298 * The cron runner now sets up a fresh PAGE and OUTPUT between each task.
1299 * The core_renderer methods notify_problem(), notify_success(), notify_message() and notify_redirect() that were
1300 deprecated in Moodle 3.1 have been removed. Use \core\notification::add(), or \core\output\notification as required.
1301 * The maximum supported precision (the total number of digits) for XMLDB_TYPE_NUMBER ("number") fields raised from 20 to
1302 38 digits. Additionally, the whole number part (precision minus scale) must not be longer than the maximum length of
1303 integer fields (20 digits). Note that PHP floats commonly support precision of roughly 15 digits only (MDL-32113).
1304 * Event triggering and event handlers:
1305 - The following events, deprecated since moodle 2.6, have been finally removed: groups_members_removed,
1306 groups_groupings_groups_removed, groups_groups_deleted, groups_groupings_deleted.
1307 * The following functions have been finally deprecated and can not be used any more:
1309 * XMLDB now validates the PATH attribute on every install.xml file. Both the XMLDB editor and installation will fail
1310 when a problem is detected with it. Please ensure your plugins contain correct directory relative paths.
1311 * Add recaptchalib_v2.php for support of reCAPTCHA v2.
1312 * Plugins can define class 'PLUGINNAME\privacy\local\sitepolicy\handler' if they implement an alternative mechanisms for
1313 site policies managements and agreements. Administrators can define which component is to be used for handling site
1314 policies and agreements.
1315 * Scripts can define a constant NO_SITEPOLICY_CHECK and set it to true before requiring the main config.php file. It
1316 will make the require_login() skipping the test for the user's policyagreed status. This is useful for plugins that
1317 act as a site policy handler.
1318 * There is a new is_fulltext_search_supported() DML function. The default implementation returns false. This function
1319 is used by 'Simple search' global search engine to determine if the database full-text search capabilities can be used.
1320 * The following have been removed from the list of core subsystems:
1323 Following this change, \core_register_renderer and \core_publish_renderer have been removed and their methods have been
1324 moved to \core_admin_renderer and \core_course_renderer respectively.
1328 * oauth2_client::request method has an extra parameter to specify the accept header for the response (MDL-60733)
1329 * The following functions, previously used (exclusively) by upgrade steps are not available
1330 anymore because of the upgrade cleanup performed for this version. See MDL-57432 for more info:
1331 - upgrade_mimetypes()
1332 - upgrade_fix_missing_root_folders_draft()
1333 - upgrade_minmaxgrade()
1334 - upgrade_course_tags()
1336 * Added new moodleform element 'filetypes' and new admin setting widget 'admin_setting_filetypes'. These new widgets
1337 allow users to define a list of file types; either by typing them manually or selecting them from a list. The widgets
1338 directly support the syntax used to feed the 'accepted_types' option of the filemanager and filepicker elements. File
1339 types can be specified as extensions (.jpg or just jpg), mime types (text/plain) or groups (image).
1340 * Removed accesslib private functions: load_course_context(), load_role_access_by_context(), dedupe_user_access() (MDL-49398).
1341 * Internal "accessdata" structure format has changed to improve ability to perform role definition caching (MDL-49398).
1342 * Role definitions are no longer cached in user session (MDL-49398).
1343 * External function core_group_external::get_activity_allowed_groups now returns an additional field: canaccessallgroups.
1344 It indicates whether the user will be able to access all the activity groups.
1345 * file_get_draft_area_info does not sum the root folder anymore when calculating the foldercount.
1346 * The moodleform element classes can now optionally provide a public function validateSubmitValue(). This method can be
1347 used to perform implicit validation of submitted values - without the need to explicitly add the validation rules to
1348 every form. The method should accept a single parameter with the submitted value. It should return a string with the
1349 eventual validation error, or an empty value if the validation passes.
1350 * New user_picture attribute $includefullname to determine whether to include the user's full name with the user's picture.
1351 * Enrol plugins which provide enrolment actions can now declare the following "data-action" attributes in their implementation of
1352 enrol_plugin::get_user_enrolment_actions() whenever applicable:
1353 * "editenrolment" - For editing a user'e enrolment details. Defined by constant ENROL_ACTION_EDIT.
1354 * "unenrol" - For unenrolling a student. Defined by constant ENROL_ACTION_UNENROL.
1355 These attributes enable enrol actions to be rendered via modals. If not added, clicking on the enrolment action buttons will still
1356 redirect the user to the appropriate enrolment action page. Though optional, it is recommended to add these attributes for a
1357 better user experience when performing enrol actions.
1358 * The enrol_plugin::get_user_enrolment_actions() implementations for core enrol plugins have been removed and moved to
1359 the parent method itself. New enrol plugins don't have to implement get_user_enrolment_actions(), but just need to
1360 make sure that they override:
1361 - enrol_plugin::allow_manage(), and/or
1362 - enrol_plugin::allow_unenrol_user() or enrol_plugin::allow_unenrol()
1363 Existing enrol plugins that override enrol_plugin::get_user_enrolment_actions() don't have to do anything, but can
1364 also opt to remove their own implementation of the method if they basically have the same logic as the parent method.
1365 * New optional parameter $enrolid for the following functions:
1366 - get_enrolled_join()
1367 - get_enrolled_sql()
1368 - get_enrolled_with_capabilities_join()
1369 Setting this parameter to a non-zero value will add a condition to the query such that only users that were enrolled
1370 with this enrolment method will be returned.
1371 * New optional parameter 'closeSuggestionsOnSelect' for the enhance() function for form-autocomplete. Setting this to true will
1372 close the suggestions popup immediately after an option has been selected. If not specified, it defaults to true for single-select
1373 elements and false for multiple-select elements.
1374 * user_can_view_profile() now also checks the moodle/user:viewalldetails capability.
1375 * The core/modal_confirm dialogue has been deprecated. Please use the core/modal_save_cancel dialogue instead. Please ensure you
1376 update to use the ModalEvents.save and ModalEvents.cancel events instead of their yes/no counterparts.
1377 * Instead of checking the 'moodle/course:viewparticipants' and 'moodle/site:viewparticipants' capabilities use the
1378 new functions course_can_view_participants() and course_require_view_participants().
1379 * $stored_file->add_to_curl_request() now adds the filename to the curl request.
1380 * The option for Login HTTPS (authentication-only SSL) has been removed
1381 * $CFG->loginhttps is now deprecated, do not use it.
1382 * $PAGE->https_required and $PAGE->verify_https_required() are now deprecated. They are no longer used and will throw a coding_exception.
1383 * $CFG->httpswwwroot is now deprecated and will always result in the same value as wwwroot.
1384 * Added function core_role_set_view_allowed() to check if a user should be able to see a given role.
1385 This should be checked whenever displaying a list of roles to a user, however, core_role_set_assign_allowed may need to override it
1387 * Deprecated allow_override, allow_assign and allow_switch and replaced with core_role_set_*_allowed to avoid function names conflicting.
1391 * ldap_get_entries_moodle() now always returns lower-cased attribute names in the returned entries.
1392 It was suppposed to do so before, but it actually didn't.
1396 * Behat compatibility changes are now being documented at https://moodledev.io
1397 * PHPUnit's bootstrap has been changed to use HTTPS wwwroot (https://www.example.com/moodle) from previous HTTP version. Any
1398 existing test expecting the old HTTP URLs will need to be switched to the new HTTPS value (reference: MDL-54901).
1399 * The information returned by the idp list has changed. This is usually only rendered by the login page and login block.
1400 The icon attribute is removed and an iconurl attribute has been added.
1401 * Support added for a new type of external file: FILE_CONTROLLED_LINK. This is an external file that Moodle can control
1402 the permissions. Moodle makes files read-only but can grant temporary write access.
1403 When accessing a URL, the info from file_browser::get_file_info will be checked to determine if the user has write access,
1404 if they do - the remote file will have access controls set to allow editing.
1405 * The method moodleform::after_definition() has been added and can now be used to add some logic
1406 to be performed after the form's definition was set. This is useful for intermediate subclasses.
1407 * Moodle has support for font-awesome icons. Plugins should use the xxx_get_fontawesome_icon_map callback
1408 to map their custom icons to one from font-awesome.
1409 * $OUTPUT->pix_url() has been deprecated because it is was used mostly to manually generate image tags for icons.
1410 We now distinguish between icons and "small images". The difference is that an icon does not have to be rendered as an image tag
1411 with a source. It is OK to still have "small images" - if this desired use $OUTPUT->image_icon() and $OUTPUT->image_url(). For
1412 other uses - use $OUTPUT->pix_icon() or the pix helper in mustache templates {{#pix}}...{{/pix}}
1413 For other valid use cases use $OUTPUT->image_url().
1414 * Activity icons have been split from standard icons. Use $OUTPUT->image_icon instead of $OUTPUT->pix_icon for these
1415 type of icons (the coloured main icon for each activity).
1416 * YUI module moodle-core-formautosubmit has been removed, use jquery .change() instead (see lib/templates/url_select.mustache for
1418 * $mform->init_javascript_enhancement() is deprecated and no longer does anything. Existing uses of smartselect enhancement
1419 should be switched to the searchableselector form element or other solutions.
1420 * Return value of the validate_email() is now proper boolean as documented. Previously the function could return 1, 0 or false.
1421 * The mcore YUI rollup which included various YUI modules such as moodle-core-notification is no longer included on every
1422 page. Missing YUI depdencies may be exposed by this change (e.g. missing a requirement on moodle-core-notification when
1423 using M.core.dialogue).
1424 * Various legacy javascript functions have been removed:
1425 * M.util.focus_login_form and M.util.focus_login_error no longer do anything. Please use jquery instead. See
1426 lib/templates/login.mustache for an example.
1427 * Some outdated global JS functions have been removed and should be replaced with calls to jquery
1428 or alternative approaches:
1429 checkall, checknone, select_all_in_element_with_id, select_all_in, deselect_all_in, confirm_if, findParentNode,
1430 filterByParent, stripHTML
1431 * M.util.init_toggle_class_on_click has been removed.
1432 * The following functions have been deprecated and should not be used any more:
1433 - file_storage::try_content_recovery - See MDL-46375 for more information
1434 - file_storage::content_exists - See MDL-46375 for more information
1435 - file_storage::deleted_file_cleanup - See MDL-46375 for more information
1436 - file_storage::get_converted_document
1437 - file_storage::is_format_supported_by_unoconv
1438 - file_storage::can_convert_documents
1439 - file_storage::send_test_pdf
1440 - file_storage::test_unoconv_path
1441 * Following behat steps have been removed from core:
1442 - I click on "<element_string>" "<selector_string>" in the "<row_text_string>" table row
1443 - I go to notifications page
1444 - I add "<filename_string>" file from recent files to "<filepicker_field_string>" filepicker
1445 - I upload "<filepath_string>" file to "<filepicker_field_string>" filepicker
1446 - I create "<foldername_string>" folder in "<filepicker_field_string>" filepicker
1447 - I open "<foldername_string>" folder from "<filepicker_field_string>" filepicker
1448 - I unzip "<filename_string>" file from "<filepicker_field_string>" filepicker
1449 - I zip "<filename_string>" folder from "<filepicker_field_string>" filepicker
1450 - I delete "<file_or_folder_name_string>" from "<filepicker_field_string>" filepicker
1451 - I send "<message_contents_string>" message to "<username_string>"
1452 - I add "<user_username_string>" user to "<cohort_idnumber_string>" cohort
1453 - I add "<username_string>" user to "<group_name_string>" group
1454 - I fill in "<field_string>" with "<value_string>"
1455 - I select "<option_string>" from "<select_string>"
1456 - I select "<radio_button_string>" radio button
1457 - I check "<option_string>"
1458 - I uncheck "<option_string>"
1459 - the "<field_string>" field should match "<value_string>" value
1460 - the "<checkbox_string>" checkbox should be checked
1461 - the "<checkbox_string>" checkbox should not be checked
1462 - I fill the moodle form with:
1463 - "<element_string>" "<selector_string>" should exists
1464 - "<element_string>" "<selector_string>" should not exists
1465 - the following "<element_string>" exists:
1466 * get_user_capability_course() now has an additional parameter 'limit'. This can be used to return a set number of records with
1467 the submitted capability. The parameter 'fieldsexceptid' will now accept context fields which can be used for preloading.
1468 * The caching option 'immutable' has been added to send_stored_file() and send_file().
1469 * New adhoc task refresh_mod_calendar_events_task that updates existing calendar events of modules.
1470 * New 'priority' column for the event table to determine which event to show in case of events with user and group overrides.
1471 * Webservices core_course_search_courses and core_course_get_courses_by_field will always return the sortorder field.
1472 * core_course_external::get_activities_overview has been deprecated. Please do not call this function any more.
1473 * Changed the pix mustache template helper to accept context variables for the key, component and alt text.
1474 * New auth_plugin_base helper methods:
1475 - get_identity_providers() - Retrieves available auth identity providers.
1476 - prepare_identity_providers_for_output() - Prepares auth identity provider data for output (e.g. to templates, WS, etc.).
1480 * Custom roles with access to any part of site administration that do not use the manager archetype will need
1481 moodle/site:configview capability added.
1482 * Admin setting "Show My courses expanded on Dashboard" has been removed.
1483 * Some backwards and forwards compatibility has been added for different bootstrap versions.
1484 This is to allow the same markup to work in "clean" and "boost" themes alot of the time. It is also to allow user text
1485 with bootstrap classes to keep working in the new theme. See MDL-56004 for the list of supported classes.
1486 * MForms element 'submitlink' has been deprecated.
1487 * Searchable selector form element is now a wrapper for autocomplete. A "No selection" option is automatically
1488 added to the options list for best backwards compatibility - if you were manually adding a "no selection" option you will need
1490 * Node.js versions >=4 are now required to run grunt.
1491 * JQuery has been updated to 3.1.0. JQuery migrate plugins are no longer shipped - please read
1492 https://jquery.com/upgrade-guide/3.0/ and update your javascript.
1493 * New option 'blanktarget' added to format_text. This option adds target="_blank" to links
1494 * A new webservice structure `external_files` has been created which provides a standardised view of files in Moodle and
1495 should be used for all file return descriptions.
1496 Files matching this format can be retrieved via the new `external_util::get_area_files` method.
1497 See MDL-54951 for further information.
1498 * The parameter $usepost of the following functions has been deprecated and is not used any more:
1499 - get_max_upload_file_size()

1501 * The following classes have been removed and should not be used any more:
1502 - boxclient - See MDL-49599 for more information.
1503 * The following functions have been removed and should not be used any more:
1504 - file_modify_html_header() - See MDL-29738 for more information.
1505 * core_grades_external::get_grades has been deprecated. Please do not call this function any more.
1506 External function gradereport_user_external::get_grade_items can be used for retrieving the course grades information.
1507 * New option 'escape' added to format_string. When true (default), escapes HTML entities from the string
1508 * The following functions have been deprecated and are not used any more:
1509 - get_records_csv() Please use csv_import_reader::load_csv_content() instead.
1510 - put_records_csv() Please use download_as_dataformat (lib/dataformatlib.php) instead.
1511 - zip_files() - See MDL-24343 for more information.
1512 - unzip_file() - See MDL-24343 for more information.
1513 - print_log() - See MDL-43681 for more information

1522 - prevent_form_autofill_password() Please do not use anymore.
1523 * The password_compat library was removed as it is no longer required.
1524 * Phpunit has been upgraded to 5.4.x and following has been deprecated and is not used any more:
1525 - setExpectedException(), use @expectedException or $this->expectException() and $this->expectExceptionMessage()
1526 - getMock(), use createMock() or getMockBuilder()->getMock()
1527 - UnitTestCase class is removed.
1528 * The following methods have been finally deprecated and should no longer be used:
1529 - course_modinfo::build_section_cache()
1530 - cm_info::get_deprecated_group_members_only()
1531 - cm_info::is_user_access_restricted_by_group()

1534 - cm_info::get_after_link()
1535 - cm_info::get_content()
1536 - cm_info::get_custom_data()
1537 - cm_info::get_extra_classes()
1538 - cm_info::get_on_click()
1539 - cm_info::get_url()
1540 - cm_info::obtain_dynamic_data()
1541 Calling them through the magic method __call() will throw a coding exception.
1542 * The alfresco library has been removed from core. It was an old version of
1543 the library which was not compatible with newer versions of Alfresco.
1544 * Added down arrow: $OUTPUT->darrow.
1545 * All file_packer implementations now accept an additional parameter to allow a simple boolean return value instead of
1546 an array of individual file statuses.
1547 * "I set the field "field_string" to multiline:" now end with colon (:), as PyStrings is supposed to end with ":"
1548 * New functions to support deprecation of events have been added to the base event. See MDL-46214 for further details.
1549 * A new function `get_name_with_info` has been added to the base event. This function adds information about event
1550 deprecations and should be used where this information is relevant.
1551 * Following api's have been deprecated in behat_config_manager, please use behat_config_util instead.
1552 - get_features_with_tags
1553 - get_components_steps_definitions
1554 - get_config_file_contents
1555 - merge_behat_config
1557 - profile_guided_allocate
1560 - get_behat_tests_path
1561 * behat_util::start_test_mode() accepts 3 options now:
1562 - 1. Theme sute with all features: If behat should initialise theme suite with all core features.
1563 - 2. Parallel runs: How many parallel runs will be running.
1564 - 3. Run: Which process behat should be initialise for.
1565 * behat_context_helper::set_session() has been deprecated, please use behat_context_helper::set_environment() instead.
1566 * data-fieldtype="type" attribute has been added to form field default template.
1567 * form elements extending MoodleQuickForm_group must call $this->createFormElement() instead of
1568 @MoodleQuickForm::createElement() in order to be compatible with PHP 7.1
1569 * Relative paths in $CFG->alternateloginurl will be resolved to absolute path within moodle site. Previously they
1570 were resolved to absolute path within the server. That means:
1571 - $CFG->wwwroot: http://example.com/moodle
1572 - $CFG->alternateloginurl : /my/super/login.php
1573 - Login url will be: http://example.com/moodle/my/super/login.php (moodle root based)
1574 * Database (DML) layer:
1575 - new sql_equal() method available for places where case sensitive/insensitive varchar comparisons are required.
1576 * PostgreSQL connections now use advanced options to reduce connection overhead. These options are not compatible
1577 with some connection poolers. The dbhandlesoptions parameter has been added to allow the database to configure the
1578 required defaults. The parameters that are required in the database are;
1579 ALTER DATABASE moodle SET client_encoding = UTF8;
1580 ALTER DATABASE moodle SET standard_conforming_strings = on;
1581 ALTER DATABASE moodle SET search_path = 'moodle,public'; -- Optional, if you wish to use a custom schema.
1582 You can set these options against the database or the moodle user who connects.
1583 * Some form elements have been refined to better support right-to-left languages. In RTL,
1584 most fields should not have their direction flipped, a URL, a path to a file, a number, ...
1585 are always displayed LTR. Input fields and text areas now will best guess whether they
1586 should be forced to be displayed in LTR based on the PARAM type associated with it. You
1587 can call $mform->setForceLtr($elementName, true/false) on some form fields to manually
1589 * Action menus do_not_enhance() is deprecated, use a list of action_icon instead.
1590 * The user_not_fully_set_up() function has a new $strict parameter (defaulting to true) in order to decide when
1591 custom fields (and other checks) should be evaluated to determine if the user has been completely setup.
1592 * profile_field_base class has new methods: get_field_config_for_external() and get_field_properties().
1593 This two new methods should be implemented by profile field plugins to make them compatible with Web Services.
1594 * The minifier library used by core_minify has been switched to https://github.com/matthiasmullie/minify - there are minor differences
1596 * context_header additional buttons can now have a class attribute provided in the link attributes.
1597 * The return signature for the antivirus::scan_file() function has changed.
1598 The calling function will now handle removal of infected files from Moodle based on the new integer return value.
1599 * The first parameter $eventdata of both message_send() and \core\message\manager::send_message() should
1600 be \core\message\message. Use of stdClass is deprecated.
1601 * The message_sent event now expects other[courseid] to be always set, exception otherwise. For BC with contrib code,
1602 message_sent::create_from_ids() will show a debugging notice if the \core\message\message being sent is missing
1603 the courseid property, defaulting to SITEID automatically. In Moodle 3.6 (MDL-55449) courseid will be fully mandatory
1604 for all messages sent.
1605 * The send_confirmation_email() function has a new optional parameter $confirmationurl to provide a different confirmation URL.
1606 * Introduced a new hook for plugin developers:
1607 - <component>_course_module_background_deletion_recommended()
1608 This hook should be used in conjunction with the existing '<component>_pre_course_module_delete($mod)'. It must
1609 return a boolean and is called by core to check whether a plugin's implementation of
1610 <component>_pre_course_module_deleted($mod) will take a long time. A plugin should therefore only implement this
1611 function if it also implements <component>_pre_course_module_delete($mod).
1612 An example in current use is recyclebin, which performs what can be a lengthy backup process in
1613 tool_recyclebin_pre_course_module_delete. The recyclebin, if enabled, now returns true in its implementation of
1614 tool_recyclebin_course_module_background_deletion_recommended(), to indicate to core that the deletion (and
1615 execution of tool_recyclebin_pre_course_module_delete) should be handled with an adhoc task, meaning it will not
1620 * Webservice function core_course_search_courses accepts a new parameter 'limittoenrolled' to filter the results
1621 only to courses the user is enrolled in, and are visible to them.
1622 * External functions that are not calling external_api::validate_context are buggy and will now generate
1623 exceptions. Previously they were only generating warnings in the webserver error log.
1624 See https://moodledev.io/docs/apis/subsystems/external/security
1625 * The moodle/blog:associatecourse and moodle/blog:associatemodule capabilities has been removed.
1626 * The following functions has been finally deprecated and can not be used any more:
1627 - profile_display_badges()
1628 - useredit_shared_definition_preferences()
1629 - calendar_normalize_tz()
1630 - get_user_timezone_offset()
1631 - get_timezone_offset()
1632 - get_list_of_timezones()
1633 - calculate_user_dst_table()
1634 - dst_changes_for_year()
1635 - get_timezone_record()
1636 - test_get_list_of_timezones()
1637 - test_get_timezone_offset()
1638 - test_get_user_timezone_offset()
1639 * The google api library has been updated to version 1.1.7. There was some important changes
1640 on the SSL handling. Now the SSL version will be determined by the underlying library.
1641 For more information see https://github.com/googleapis/google-api-php-client/pull/644
1642 * The get_role_users() function will now add the $sort fields that are not part
1643 of the requested fields to the query result and will throw a debugging message
1644 with the added fields when that happens.
1645 * The core_user::fill_properties_cache() static method has been introduced to be a reference
1646 and allow standard user fields data validation. Right now only type validation is supported
1647 checking it against the parameter (PARAM_*) type of the target user field. MDL-52781 is
1648 going to add support to null/not null and choices validation, replacing the existing code to
1649 validate the user fields in different places in a common way.
1650 * Webservice function core_course_search_courses now returns results when the search string
1651 is less than 2 chars long.
1652 * Webservice function core_course_search_courses accepts a new parameter 'requiredcapabilities' to filter the results
1653 by the capabilities of the current user.
1654 * New mform element 'course' handles thousands of courses with good performance and usability.
1655 * The redirect() function will now redirect immediately if output has not
1656 already started. Messages will be displayed on the subsequent page using
1657 session notifications. The type of message output can be configured using the
1658 fourth parameter to redirect().
1659 * The specification of extra classes in the $OUTPUT->notification()
1660 function, and \core\output\notification renderable have been deprecated
1661 and will be removed in a future version.
1662 Notifications should use the levels found in \core\output\notification.
1663 * The constants for NOTIFY_PROBLEM, NOTIFY_REDIRECT, and NOTIFY_MESSAGE in
1664 \core\output\notification have been deprecated in favour of NOTIFY_ERROR,
1665 NOTIFY_WARNING, and NOTIFY_INFO respectively.
1666 * The following functions, previously used (exclusively) by upgrade steps are not available
1667 anymore because of the upgrade cleanup performed for this version. See MDL-51580 for more info:
1668 - upgrade_mysql_fix_unsigned_and_lob_columns()
1669 - upgrade_course_completion_remove_duplicates()
1670 - upgrade_save_orphaned_questions()
1671 - upgrade_rename_old_backup_files_using_shortname()
1672 - upgrade_mssql_nvarcharmax()
1673 - upgrade_mssql_varbinarymax()
1674 - upgrade_fix_missing_root_folders()
1675 - upgrade_course_modules_sequences()
1676 - upgrade_grade_item_fix_sortorder()
1677 - upgrade_availability_item()
1678 * A new parameter $ajaxformdata was added to the constructor for moodleform. When building a
1679 moodleform in a webservice or ajax script (for example using the new fragments API) we
1680 cannot allow the moodleform to parse it's own data from _GET and _POST - we must pass it as
1682 * Plugins can extend the navigation for user by declaring the following callback:
1683 <frankenstyle>_extend_navigation_user(navigation_node $parentnode, stdClass $user,
1684 context_user $context, stdClass $course,
1685 context_course $coursecontext)
1686 * The function notify() now throws a debugging message - see MDL-50269.
1687 * Ajax calls going through lib/ajax/* now validate the return values before sending
1688 the response. If the validation does not pass an exception is raised. This behaviour
1689 is consistent with web services.
1690 * Several changes in Moodle core, standard plugins and third party libraries to
1691 ensure compatibility with PHP7. All plugins are recommended to perform testing
1692 against PHP7 as well. Refer to https://moodledev.io/general/development/policies/php for more
1693 information. The following changes may affect you:
1694 * Class moodleform, moodleform_mod and some module classes have been changed to use
1695 __construct() for the constructor. Calling parent constructors by the class
1696 name will display debugging message. Incorrect: parent::moodleform(),
1697 correct: parent::__construct()
1698 * All form elements have also changed the constructor syntax. No changes are
1699 needed for using form elements, however if plugin defines new form element it
1700 needs to use correct syntax. For example, incorrect: parent::HTML_QuickForm_input(),
1701 HTML_QuickForm_input::HTML_QuickForm_input(), $this->HTML_QuickForm_input().
1702 Correct: HTML_QuickForm_input::__construct() or parent::__construct().
1703 * profile_field_base::profile_field_base() is deprecated, use parent::__construct()
1704 in custom profile fields constructors. Similar deprecations in exsiting
1705 profile_field_* classes.
1706 * user_filter_type::user_filter_type() is deprecated, use parent::__construct() in
1707 custom user filters. Similar deprecations in existing user_filter_* classes.
1708 * table_default_export_format_parent::table_default_export_format_parent() is
1709 deprecated, use parent::__construct() in extending classes.
1710 * groups_delete_group_members() $showfeedback parameter has been removed and is no longer
1711 respected. Users of this function should output their own feedback if required.
1712 * Number of changes to Tags API, see tag/upgrade.txt for more details
1713 * The previous events API handlers are being deprecated in favour of events 2 API, debugging messages are being displayed if
1714 there are 3rd party plugins using it. Switch to events 2 API please, see https://docs.moodle.org/dev/Events_API#Event_dispatching_and_observers
1715 Note than you will need to bump the plugin version so moodle is aware that you removed the plugin's event handlers.
1716 * mforms validation functions are not available in the global JS namespace anymore, event listeners
1717 are assigned to fields and buttons through a self-contained JS function.
1718 * Added $CFG->urlrewriteclass option to config.php allowing clean / semantic urls to
1719 be implemented in a plugin, eg local_cleanurls.
1720 * $CFG->pathtoclam global setting has been moved to clamav antivirus plugin setting of the same name.
1721 * clam_message_admins() and get_clam_error_code() have been deprecated, its functionality
1722 is now a part of \antivirus_clamav\scanner class methods.
1723 * \repository::antivir_scan_file() has been deprecated, \core\antivirus\manager::scan_file() that
1724 applies antivirus plugins is replacing its functionality.
1725 * Added core_text::str_max_bytes() which safely truncates multi-byte strings to a maximum number of bytes.
1726 * Zend Framework has been removed completely.
1727 * Any plugin can report when a scale is being used with the callback function [pluginname]_scale_used_anywhere(int $scaleid).
1728 * Changes in file_rewrite_pluginfile_urls: Passing a new option reverse = true in the $options var will make the function to convert
1729 actual URLs in $text to encoded URLs in the @@PLUGINFILE@@ form.
1730 * behat_util::is_server_running() is removed, please use behat_util::check_server_status() instead.
1731 * Behat\Mink\Selector\SelectorsHandler::xpathLiteral() method is deprecated use behat_context_helper::escape instead
1732 when building Xpath, or pass the unescaped value when using the named selector.',
1733 * table_sql download process is using the new data formats plugin which you can't use if you are buffering any output
1734 * flexible_table::get_download_menu(), considered private, has been deleted. Use
1735 $OUTPUT->download_dataformat_selector() instead.
1736 when building Xpath, or pass the unescaped value when using the named selector.
1737 * Add new file_is_executable(), to consistently check for executables even in Windows (PHP bug #41062).
1738 * Introduced new hooks for plugin developers.
1739 - <component>_pre_course_category_delete($category)
1740 - <component>_pre_course_delete($course)
1741 - <component>_pre_course_module_delete($cm)
1742 - <component>_pre_block_delete($instance)
1743 - <component>_pre_user_delete($user)
1744 These hooks allow developers to use the item in question before it is deleted by core. For example, if your plugin is
1745 a module (plugins located in the mod folder) called 'xxx' and you wish to interact with the user object before it is
1746 deleted then the function to create would be mod_xxx_pre_user_delete($user) in mod/xxx/lib.php.
1747 * pear::Net::GeoIP has been removed.
1751 * Minify updated to 2.2.1
1752 * htmlpurifier upgraded to 4.7.0
1753 * Less.php upgraded to 1.7.0.9
1754 * The horde library has been updated to version 5.2.7.
1755 * Google libraries (lib/google) updated to 1.1.5
1756 * Html2Text library has been updated to the latest version of the library.
1757 * External functions x_is_allowed_from_ajax() methods have been deprecated. Define 'ajax' => true in db/services.php instead.
1758 * External functions can be called without a session if they define 'loginrequired' => true in db/services.php.
1759 * All plugins are required to declare their frankenstyle component name via
1760 the $plugin->component property in their version.php file. See
1761 https://moodledev.io/docs/apis/commonfiles/version.php for details (MDL-48494).
1762 * PHPUnit is upgraded to 4.7. Some tests using deprecated assertions etc may need changes to work correctly.
1763 * Users of the text editor API to manually create a text editor should call set_text before calling use_editor.
1764 * Javascript - SimpleYUI and the Y instance used for modules have been merged. Y is now always the same instance of Y.
1765 * get_referer() has been deprecated, please use the get_local_referer function instead.
1766 * \core\progress\null is renamed to \core\progress\none for improved PHP7 compatibility as null is a reserved word (see MDL-50453).
1767 * \webservice_xmlrpc_client now respects proxy server settings. If your XMLRPC server is available on your local network and not via your proxy server, you may need to add it to the list of proxy
1768 server exceptions in $CFG->proxybypass. See MDL-39353 for details.
1769 * Group and groupings idnumbers can now be passed to and/or are returned from the following web services functions:
1770 ** core_group_external::create_groups
1771 ** core_group_external::get_groups
1772 ** core_group_external::get_course_groups
1773 ** core_group_external::create_groupings
1774 ** core_group_external::update_groupings
1775 ** core_group_external::get_groupings
1776 ** core_group_external::get_course_groupings
1777 ** core_group_external::get_course_user_groups
1778 * Following functions are removed from core. See MDL-50049 for details.

1886 * The never unused webdav_locks table was dropped.
1887 * The actionmenu hideMenu() function now expects an EventFacade object to be passed to it,
1888 i.e. a call to M.core.actionmenu.instance.hideMenu() should be change to M.core.actionmenu.instance.hideMenu(e)
1889 * In the html_editors (tinyMCE, Atto), the manage files button can be hidden by changing the 'enable_filemanagement' option to false.
1890 * external_api::validate_context now is public, it can be called from other classes.
1891 * rss_error() now supports returning of correct HTTP status of error and will return '404 Not Found'
1892 unless other status is specified.
1893 * Plugins can extend the navigation for categories settings by declaring the following callback:
1894 <frankenstyle>_extend_navigation_category_settings(navigation_node, context_coursecat)
1895 * The clilib.php provides two new functions cli_write() and cli_writeln() that should be used for outputting texts from the command
1896 line interface scripts.
1897 * External function core_course_external::get_course_contents returned parameter "name" has been changed to PARAM_RAW,
1898 this is because the new external_format_string function may return raw data if the global moodlewssettingraw parameter is used.
1899 * Function is_web_crawler() has been deprecated, please use core_useragent::is_web_crawler() instead.
1903 * New methods grade_grade::get_grade_max() and get_grade_min() must be used rather than directly the public properties rawgrademax and rawgrademin.
1904 * New method grade_item::is_aggregate_item() indicates when a grade_item is an aggreggated type grade.
1908 * The default home page for users has been changed to the dashboard (formely my home). See MDL-45774.
1909 * Support for rendering templates from php or javascript has been added. See MDL-49152.
1910 * Support for loading AMD javascript modules has been added. See MDL-49046.
1911 * Webservice core_course_delete_courses now return warning messages on any failures and does not try to rollback the entire deletion.
1912 * \core\event\course_viewed 'other' argument renamed from coursesectionid to coursesectionnumber as it contains the section number.
1913 * New API core_filetypes::add_type (etc.) allows custom filetypes to be added and modified.
1914 * PHPUnit: PHPMailer Sink is now started for all tests and is setup within the phpunit wrapper for advanced tests.
1915 Catching debugging messages when sending mail will no longer work. Use $sink = $this->redirectEmails(); and then check
1916 the message in the sink instead.
1917 * The file pluginlib.php was deprecated since 2.6 and has now been removed, do not include or require it.
1918 * \core_component::fetch_subsystems() now returns a valid path for completion component instead of null.
1919 * Deprecated JS global methods have been removed (show_item, destroy_item, hide_item, addonload, getElementsByTagName, findChildNodes).
1920 * For 3rd party plugin specific environment.xml files, it's now possible to specify version independent checks by using the
1921 <PLUGIN name="component_name"> tag instead of the version dependent <MOODLE version="x.y"> one. If the PLUGIN tag is used any
1922 Moodle specific tags will be ignored.
1923 * html_table: new API for adding captions to tables (new field, $table->caption) and subsequently hiding said captions from sighted users using accesshide (enabled using $table->captionhide).
1924 * The authorization procedure in the mdeploy.php script has been improved. The script
1925 now relies on the main config.php when deploying an available update.
1926 * sql_internal_reader and sql_select_reader interfaces have been deprecated in favour of sql_internal_table_reader
1927 and sql_reader which use iterators to be more memory efficient.
1928 * $CFG->enabletgzbackups setting has been removed as now backups are stored internally using .tar.gz format by default, you can
1929 set $CFG->usezipbackups to store them in zip format. This does not affect the restore process, which continues accepting both.
1930 * Added support for custom string manager implementations via $CFG->customstringmanager
1931 directive in the config.php. See MDL-49361 for details.
1932 * Add new make_request_directory() for creation of per-request files.
1933 * Added generate_image_thumbnail_from_string. This should be used instead of generate_image_thumbnail when the source is a string.
1934 This prevents the need to write files to disk unnecessarily.
1935 * Added generate_image_thumbnail to stored_file class. This should be used when generating thumbnails for stored files.
1936 This prevents the need to write files to disk unnecessarily.
1937 * Removed pear/HTTP/WebDav. See MDL-49534 for details.
1938 * Use standard PHP date time classes and methods - see new core_date class for timezone normalisation methods.
1939 * Moved lib/google/Google/ to lib/google/src/Google. This is to address autoloader issues with Google's provided autoloader
1940 for the library. See MDL-49519 for details.
1941 * The outdated lib/google/Google_Client.php and related files have been completely removed. To use
1942 the new client, read lib/google/readme_moodle.txt, please.
1943 * profile_display_badges() has been deprecated. See MDL-48935 for details.
1944 * Added a new method add_report_nodes() to pagelib.php. If you are looking to add links to the user profile page under the heading "Reports"
1945 then please use this function to ensure that the breadcrumb and navigation block are created properly for all user profile pages.
1946 * process_new_icon() now does not always return a PNG file. When possible, it will try to keep the format of the original file.
1947 Set the new argument $preferpng to true to force PNG. See MDL-46763 and MDL-50041 for details.
1951 * Gradebook grade category option "aggregatesubcats" has been removed completely.
1952 This means that the database column is removed, the admin settings are removed and
1953 the properties from the grade_category object have been removed. If any courses were
1954 found to be using this setting, a warning to check the grades will be shown in the
1955 course grader report after upgrading the site. The same warning will be shown on
1956 courses restored from backup that had this setting enabled (see MDL-47503).
1957 * lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.
1958 * renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
1959 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
1960 you will need to change the name of your render method to "render_blah" instead, as renderable at the end is no longer accepted.
1961 * New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
1962 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
1963 more efficiently load these basic data objects at the start of a script.
1964 * New function cm_info::create($cm) can be used when you need a cm_info
1965 object, but have a $cm which might only be a standard database record.
1966 * $CFG->enablegroupmembersonly no longer exists.
1967 * Scheduled tasks have gained support for syntax to introduce variability when a
1968 task will run across installs. When a when hour or minute are defined as 'R'
1969 they will be installed with a random hour/minute value.
1970 * Several classes grade_edit_tree_column_xxx were removed since grades setup page
1971 has been significantly changed. These classes should not be used outside of
1972 gradebook or developers can copy them into their plugins from 2.7 branch.
1973 * Google APIs Client Library (lib/google/) has been upgraded to 1.0.5-beta and
1974 API has changed dramatically without backward compatibility. Any code accessing
1975 it must be amended. It does not apply to lib/googleapi.php. See MDL-47297
1976 * Added an extra parameter to the function get_formatted_help_string() (default null) which is used to specify
1977 additional string parameters.
1978 * User settings node and course node in navigation now support callbacks from admin tools.
1979 * grade_get_grades() optional parameteres $itemtype, $itemmodule, $iteminstance are now required.
1982 * completion_info->get_incomplete_criteria() is deprecated and will be removed in Moodle 3.0.
1983 * grade_category::aggregate_values() is deprecated and will be removed in Moodle 3.0.
1984 * groups_filter_users_by_course_module_visible() is deprecated; replace with
1985 core_availability\info::filter_user_list. Will be removed in Moodle 3.0.
1986 * groups_course_module_visible() is deprecated; replace with $cm->uservisible.
1987 * cm_info property $cm->groupmembersonly is deprecated and always returns 0.
1988 Use core_availability\info::filter_user_list if trying to determine which
1989 other users can see an activity.
1990 * cm_info method $cm->is_user_access_restricted_by_group() is deprecated and
1991 always returns false. Use $cm->uservisible to determine whether the user can
1992 access the activity.
1993 * Constant FEATURE_GROUPMEMBERSONLY (used in module _supports functions) is
1995 * cohort_get_visible_list() is deprecated. There is a better function cohort_get_available_cohorts()
1996 that respects user capabilities to view cohorts.
1997 * enrol_cohort_get_cohorts() and enrol_cohort_search_cohorts() are deprecated since
1998 functionality is removed. Please use cohort_get_available_cohorts()
1999 * enrol_cohort_enrol_all_users() is deprecated; enrol_manual is now responsible for this action
2000 * enrol_cohort_can_view_cohort() is deprecated; replace with cohort_can_view_cohort()
2002 === 2.6.4 / 2.7.1 ===
2004 * setnew_password_and_mail() and update_internal_user_password() will trigger
2005 \core\event\user_password_updated. Previously they used to generate
2006 \core\event\user_updated event.
2007 * update_internal_user_password() accepts optional boolean $fasthash for fast
2009 * user_update_user() and user_create_user() api's accept optional param
2010 $triggerevent to avoid respective events to be triggred from the api's.
2014 * PHPUnit cannot be installed via PEAR any more, please use composer package manager instead.
2015 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
2018 * Significant changes in Logging API. For upgrading existing events_trigger() and
2019 add_to_log() see http://docs.moodle.org/dev/Migrating_logging_calls_in_plugins
2020 For accessing logs from plugins see http://docs.moodle.org/dev/Migrating_log_access_in_reports
2021 * The validation of the following events is now stricter (see MDL-45445):
2022 - \core\event\blog_entry_created
2023 - \core\event\blog_entry_deleted
2024 - \core\event\blog_entry_updated

2045 - \core\event\user_profile_viewed
2046 - \core\event\webservice_token_created
2049 * $module uses in mod/xxx/version.php files is now deprecated. Please use $plugin instead. It will be removed in Moodle 2.10.
2050 * Update init methods in all event classes - "level" property was renamed to "edulevel", the level property is now deprecated.
2051 * Abstract class \core\event\course_module_instances_list_viewed is deprecated now, use \core\event\instances_list_viewed instead.
2052 * Abstract class core\event\content_viewed has been deprecated. Please extend base event or other relevant abstract class.
2053 * mod_book\event\instances_list_viewed has been deprecated. Please use mod_book\event\course_module_instance_list_viewed instead.
2054 * mod_chat\event\instances_list_viewed has been deprecated. Please use mod_chat\event\course_module_instance_list_viewed instead.
2055 * mod_choice\event\instances_list_viewed has been deprecated. Please use mod_choice\event\course_module_instance_list_viewed instead.
2056 * mod_feedback\event\instances_list_viewed has been deprecated. Please use mod_feedback\event\course_module_instance_list_viewed instead.
2057 * mod_page\event\instances_list_viewed has been deprecated. Please use mod_page\event\course_module_instance_list_viewed instead.
2058 * The constants FRONTPAGECOURSELIST, FRONTPAGETOPICONLY & FRONTPAGECOURSELIMIT have been removed.
2059 * Conditional availability API has moved and changed. The condition_info class is
2060 replaced by \core_availability\info_module, and condition_info_section by
2061 \core_availability\info_section. (Code that uses the old classes will generally
2063 * coursemodule_visible_for_user() has been deprecated but still works - replaced
2064 by a new static function \core_availability\info_module::is_user_visible()
2065 * cm_info::is_user_access_restricted_by_conditional_access has been deprecated
2066 but still works (it has never done what its name suggests, and is
2068 * cm_info and section_info property showavailability has been deprecated, but
2069 still works (with the caveat that this information is now per-user).
2070 * cm_info and section_info properties availablefrom and availableuntil have been
2071 deprecated and always return zero (underlying data doesn't have these values).
2072 * section_info property groupingid has been deprecated and always returns zero,
2074 * Various cm_info methods have been deprecated in favour of their read-only properties (get_url(), get_content(), get_extra_classes(),
2075 get_on_click(), get_custom_data(), get_after_link, get_after_edit_icons)
2076 * The ajaxenabled function has been deprecated and always returns true. All code should be fully functional in Javascript.
2077 * count_login_failures() has been deprecated, use user_count_login_failures() instead. Refer MDL-42891 for details.
2079 Conditional availability (activities and sections):
2080 * New conditional availability API in /availability, including new availability
2081 condition plugins in /availability/condition. The new API is very similar with
2082 regard to checking availability, but any code that modifies availability settings
2083 for an activity or section is likely to need substantial changes.
2086 * The lightbox attribute for moodle-core-notification-dialogue has been
2087 deprecated and replaced by the modal attribute. This was actually
2088 changed in Moodle 2.2, but has only been marked as deprecated now. It
2089 will be removed in Moodle 2.9.
2090 * When destroying any type of dialogue based on moodle-core-notification, the relevant content is also removed from
2091 the DOM. Previously it was left orphaned.
2094 * The findChildNodes global function has been deprecated. Y.all should
2096 * The callback argument to confirm_action and M.util.show_confirm_dialog has been deprecated. If you need to write a
2097 confirmation which includes a callback, please use moodle-core-notification-confirmation and attach callbacks to the
2100 * New locking api and admin settings to configure the system locking type.
2101 * New "Time spent waiting for the database" performance metric displayed along with the
2102 other MDL_PERF vars; the change affects both the error logs and the vars displayed in
2104 * Changes in the tag API. The component and contextid are now saved when assigning tags to an item. Please see
2105 tag/upgrade.txt for more information.
2109 * Use new methods from core_component class instead of get_core_subsystems(), get_plugin_types(),
2110 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
2111 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
2112 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
2113 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
2114 * Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
2115 * Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
2116 * New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
2117 * MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
2118 this change should be fully transparent and it should help significantly with add-on compatibility.
2119 * The string manager classes were renamed. Note that they should not be modified or used directly,
2120 always use get_string_manager() to get instance of the string manager.
2121 * The ability to use an 'insecure' rc4encrypt/rc4decrypt key has been removed.
2122 * Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).
2123 * Use set_debugging(DEBUG_xxx) when changing debugging level for current request.
2124 * Function moveto_module() does not modify $mod argument and instead now returns the new module visibility value.
2125 * Use behat_selectors::get_allowed_text_selectors() and behat_selectors::get_allowed_selectors() instead of
2126 behat_command::$allowedtextselectors and behat_command::$allowedselectors
2127 * Subplugins are supported in admin tools and local plugins.
2128 * file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
2129 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
2130 function that returns an approximate number of entries in the zip faster than the count() function.
2131 * Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
2132 * Class course_modinfo no longer extends stdClass. All properties are read-only.
2133 * Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
2134 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
2135 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
2136 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
2138 * Internal (noreply and support) user support has been added for sending/receiving message.
2139 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
2140 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
2141 * New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
2142 * Use core_plugin_manager::reset_caches() when changing visibility of plugins.
2143 * Implement new method get_enabled_plugins() method in subplugin info classes.
2144 * Each plugin should include version information in version.php.
2145 * Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
2146 * $USER->password field is intentionally unset so that session data does not contain password hashes.
2147 * Use core_shutdown_manager::register_function() instead of register_shutdown_function().
2148 * New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
2149 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
2150 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
2151 * New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
2152 of 'fopen' to read gzip-compressed files if required.
2153 * update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
2154 * Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
2155 * New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
2156 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
2158 * $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
2159 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.
2160 * Date format locale charset for windows server will come from calendar type and for gregorian it will use
2162 * The library to interact with Box.net (class boxclient) is only compatible with their APIv1 which
2163 reaches its end of life on the 14th of Dec. You should migrate your scripts to make usage of the
2164 new class boxnet_client(). Note that the method names and return values have changed.
2165 * Settings pages are now possible for Calendar type plugins. Calendar type plugins that require a settings page to
2166 work properly will need to set their requires version to a number that is equal to or grater than the 2.6.1 release version.
2167 * The admin/tool/generator tool was overhauled to use testing data generators and the previous interface to create
2168 test data was removed (it was not working correctly anyway). If you were using this tool you will probably need to
2172 Various previously deprecated functions have now been altered to throw DEBUG_DEVELOPER debugging notices

2281 * moodle-core-notification has been deprecated with a recommendation of
2282 using its subclasses instead. This is to allow for reduced page
2283 transport costs. Current subclasses include:
2290 Event triggering and event handlers:
2291 * All existing events and event handlers should be replaced by new
2292 event classes and matching new event observers.
2293 * See https://docs.moodle.org/dev/Events_API for more information.
2294 * The following events will be entirely removed, though they can still
2295 be captured using handlers, but they should not be used any more.
2296 * groups_members_removed -> \core\event\group_member_removed
2297 * groups_groupings_groups_removed -> (no replacement)
2298 * groups_groups_deleted -> \core\event\group_deleted
2299 * groups_groupings_deleted -> \core\event\grouping_deleted
2300 * edit_module_post_actions() does not trigger events any more.
2304 * New get_course() function for use when obtaining the course record from database. Will
2305 reuse existing $COURSE or $SITE globals if possible to improve performance.
2309 * The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
2310 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
2311 apply for that change.
2312 * The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
2313 so any custom utility relying on the old output may require modification.
2314 * Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
2315 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
2316 an option for 0 bytes. Existing code that was replacing the 0 option in the return
2317 from this function with a more sensible message, can now use the return from this function directly.
2318 * Functions responsible for output in course/lib.php are deprecated, the code is moved to
2319 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),
2320 make_editing_buttons()
2321 See functions' phpdocs in lib/deprecatedlib.php
2322 * Function get_print_section_cm_text() is deprecated, replaced with methods in cm_info
2323 * zip_packer may create empty zip archives, there is a new option to ignore
2324 problematic files when creating archive
2325 * The function delete_course_module was deprecated and has been replaced with
2326 course_delete_module. The reason for this was because the function delete_course_module
2327 only partially deletes data, so wherever it was called extra code was needed to
2328 perform the whole deletion process. The function course_delete_module now takes care
2329 of the whole process.
2330 * curl::setopt() does not accept constant values any more. As it never worked properly,
2331 we decided to make the type check stricter. Now, the keys of the array pass must be a string
2332 corresponding to the curl constant name.
2333 * Function get_users_listing now return list of users except guest and deleted users. Previously
2334 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
2335 and not included in get_user function, it will not be returned by get_users_listing.
2336 * The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
2337 MODNAME_dndupload_register callback instead.
2338 * The signature of the add() method of classes implementing the parentable_part_of_admin_tree
2339 interface (such as admin_category) has been extended. The new parameter allows the caller
2340 to prepend the new node before an existing sibling in the admin tree.
2341 * condition_info:get_condition_user_fields($formatoptions) now accepts the optional
2342 param $formatoptions, that will determine if the field names are processed by
2343 format_string() with the passed options.
2344 * remove all references to $CFG->gdversion, GD PHP extension is now required
2345 * Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
2346 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.
2347 * Functions responsible for managing and accessing course categories are moved to class coursecat
2348 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
2349 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
2350 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
2351 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),
2352 get_child_categories(), get_categories(), print_my_moodle(), print_remote_course(),
2353 print_remote_host(), print_whole_category_list(), print_category_info(), get_course_category_tree(),
2354 print_courses(), print_course(), get_category_courses_array(), get_category_courses_array_recursively(),
2355 get_courses_wmanagers()
2356 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
2357 * Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
2358 functions to get information for only active (excluding suspended enrolments) users. Included two
2359 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
2360 * The core_plugin_manager class now provides two new helper methods for getting information
2361 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
2362 * The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
2363 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
2364 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
2365 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
2366 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
2367 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
2368 satisfy all plugin types.
2370 Database (DML) layer:
2371 * $DB->sql_empty() is deprecated, you have to use sql parameters with empty values instead,
2372 please note hardcoding of empty strings in SQL queries breaks execution in Oracle database.
2373 * Indexes must not be defined on the same columns as keys, this is now reported as fatal problem.
2374 Please note that internally we create indexes instead of foreign keys.
2377 * M.util.help_icon has been deprecated. Code should be updated to use moodle-core-popuphelp
2378 instead. To do so, remove any existing JS calls to M.util.help_icon from your PHP and ensure
2379 that your help link is placed in a span which has the class 'helplink'.
2383 * Pagelib: Numerous deprecated functions were removed as classes page_base, page_course
2384 and page_generic_activity.
2385 * use $CFG->googlemapkey3 instead of removed $CFG->googlemapkey and migrate to Google Maps API V3
2386 * Function settings_navigation::add_course_editing_links() is completely removed
2387 * function global_navigation::format_display_course_content() is removed completely (the
2388 functionality is moved to course format class)
2389 * in the function global_navigation::load_generic_course_sections() the argument $courseformat is
2391 * New component and itemid columns in groups_members table - this allows plugin to create protected
2392 group memberships using 'xx_yy_allow_group_member_remove' callback and there is also a new restore
2393 callback 'xx_yy_restore_group_member()'.
2394 * New general role assignment restore plugin callback 'xx_yy_restore_role_assignment()'.
2395 * functions get_generic_section_name(), get_all_sections(), add_mod_to_section(), get_all_mods()
2396 are deprecated. See their phpdocs in lib/deprecatedlib.php on how to replace them
2399 * moodle-enrol-notification has been renamed to moodle-core-notification
2400 * YUI2 code must now use 2in3, see http://yuilibrary.com/yui/docs/yui/yui-yui2.html
2401 * M.util.init_select_autosubmit() and M.util.init_url_select() have been deprecated. Code using this should be updated
2402 to use moodle-core-formautosubmit
2404 Unit testing changes:
2405 * output debugging() is not sent to standard output any more,
2406 use $this->assertDebuggingCalled(), $this->assertDebuggingNotCalled(),
2407 $this->getDebuggingMessages() or $this->assertResetDebugging() instead.
2411 Database layer changes:
2412 * objects are not allowed in paramters of DML functions, use explicit casting to strings if necessary
2415 * DDL and DML methods which were deprecated in 2.0 have now been removed, they will no longer produce
2416 debug messages and will produce fatal errors
2420 * send_stored_file() has changed its interface
2421 * deleted several resourcelib_embed_* functions from resourcelib.php
2425 removed unused libraries:
2426 * odbc, base32, CodeSniffer, overlib, apd profiling, kses, Smarty, PEAR Console, swfobject, cssshover.htc, md5.js
2429 * new admin/tool plugin type
2430 * new context API - old API is still available
2431 * deleted users do not have context any more
2432 * removed global search
2438 * basic suport for restore from 1.9
2439 * new mobile devices API
