1 This files describes API changes in core libraries and APIs,
2 information provided here is intended especially for developers.
6 * New option 'blanktarget' added to format_text. This option adds target="_blank" to links
7 * The parameter $usepost of the following functions has been deprecated and is not used any more:
8 - get_max_upload_file_size()
9 - get_user_max_upload_file_size()
10 * The following functions have been deprecated and should not be used any more:
11 - file_modify_html_header() - See MDL-29738 for more information.
15 * behat_util::is_server_running() is removed, please use behat_util::check_server_status() instead.
19 * The core_user::fill_properties_cache() static method has been introduced to be a reference
20 and allow standard user fields data validation. Right now only type validation is supported
21 checking it against the parameter (PARAM_*) type of the target user field. MDL-52781 is
22 going to add support to null/not null and choices validation, replacing the existing code to
23 validate the user fields in different places in a common way.
27 * Number of changes to allow to run Moodle on PHP7. This should not affect existing plugins
28 when running on PHP5 but it is recommended to ensure PHP7 compatibility in plugins as well.
29 From Moodle 3.1 calling parent constructors by class names will show deprecation warnings.
30 Refer to https://docs.moodle.org/dev/Moodle_and_PHP7 for more information.
34 * Minify updated to 2.2.1

40 * External functions x_is_allowed_from_ajax() methods have been deprecated. Define 'ajax' => true in db/services.php instead.
41 * External functions can be called without a session if they define 'loginrequired' => true in db/services.php.
42 * All plugins are required to declare their frankenstyle component name via
43 the $plugin->component property in their version.php file. See
44 https://docs.moodle.org/dev/version.php for details (MDL-48494).
45 * PHPUnit is upgraded to 4.7. Some tests using deprecated assertions etc may need changes to work correctly.
46 * Users of the text editor API to manually create a text editor should call set_text before calling use_editor.
47 * Javascript - SimpleYUI and the Y instance used for modules have been merged. Y is now always the same instance of Y.
48 * get_referer() has been deprecated, please use the get_local_referer function instead.
49 * \core\progress\null is renamed to \core\progress\none for improved PHP7 compatibility as null is a reserved word (see MDL-50453).
50 * \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
51 server exceptions in $CFG->proxybypass. See MDL-39353 for details.
52 * Group and groupings idnumbers can now be passed to and/or are returned from the following web services functions:

172 * In the html_editors (tinyMCE, Atto), the manage files button can be hidden by changing the 'enable_filemanagement' option to false.
173 * external_api::validate_context now is public, it can be called from other classes.
174 * rss_error() now supports returning of correct HTTP status of error and will return '404 Not Found'
175 unless other status is specified.
176 * Plugins can extend the navigation for categories settings by declaring the following callback:
177 <frankenstyle>_extend_navigation_category_settings(navigation_node, context_coursecat)
178 * The clilib.php provides two new functions cli_write() and cli_writeln() that should be used for outputting texts from the command
179 line interface scripts.
180 * External function core_course_external::get_course_contents returned parameter "name" has been changed to PARAM_RAW,
181 this is because the new external_format_string function may return raw data if the global moodlewssettingraw parameter is used.
182 * Function is_web_crawler() has been deprecated, please use core_useragent::is_web_crawler() instead.
186 * New methods grade_grade::get_grade_max() and get_grade_min() must be used rather than directly the public properties rawgrademax and rawgrademin.
187 * New method grade_item::is_aggregate_item() indicates when a grade_item is an aggreggated type grade.
191 * The default home page for users has been changed to the dashboard (formely my home). See MDL-45774.
192 * Support for rendering templates from php or javascript has been added. See MDL-49152.

194 * Webservice core_course_delete_courses now return warning messages on any failures and does not try to rollback the entire deletion.
195 * \core\event\course_viewed 'other' argument renamed from coursesectionid to coursesectionnumber as it contains the section number.
196 * New API core_filetypes::add_type (etc.) allows custom filetypes to be added and modified.
197 * PHPUnit: PHPMailer Sink is now started for all tests and is setup within the phpunit wrapper for advanced tests.
198 Catching debugging messages when sending mail will no longer work. Use $sink = $this->redirectEmails(); and then check
199 the message in the sink instead.
200 * The file pluginlib.php was deprecated since 2.6 and has now been removed, do not include or require it.
201 * \core_component::fetch_subsystems() now returns a valid path for completion component instead of null.
202 * Deprecated JS global methods have been removed (show_item, destroy_item, hide_item, addonload, getElementsByTagName, findChildNodes).
203 * For 3rd party plugin specific environment.xml files, it's now possible to specify version independent checks by using the
204 <PLUGIN name="component_name"> tag instead of the version dependent <MOODLE version="x.y"> one. If the PLUGIN tag is used any
205 Moodle specific tags will be ignored.
206 * 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).
207 * The authorization procedure in the mdeploy.php script has been improved. The script
208 now relies on the main config.php when deploying an available update.
209 * sql_internal_reader and sql_select_reader interfaces have been deprecated in favour of sql_internal_table_reader
210 and sql_reader which use iterators to be more memory efficient.
211 * $CFG->enabletgzbackups setting has been removed as now backups are stored internally using .tar.gz format by default, you can
212 set $CFG->usezipbackups to store them in zip format. This does not affect the restore process, which continues accepting both.
213 * Added support for custom string manager implementations via $CFG->customstringmanager
214 directive in the config.php. See MDL-49361 for details.
215 * Add new make_request_directory() for creation of per-request files.
216 * Added generate_image_thumbnail_from_string. This should be used instead of generate_image_thumbnail when the source is a string.
217 This prevents the need to write files to disk unnecessarily.
218 * Added generate_image_thumbnail to stored_file class. This should be used when generating thumbnails for stored files.
219 This prevents the need to write files to disk unnecessarily.
220 * Removed pear/HTTP/WebDav. See MDL-49534 for details.
221 * Use standard PHP date time classes and methods - see new core_date class for timezone normalisation methods.
222 * Moved lib/google/Google/ to lib/google/src/Google. This is to address autoloader issues with Google's provided autoloader
223 for the library. See MDL-49519 for details.
224 * The outdated lib/google/Google_Client.php and related files have been completely removed. To use
225 the new client, read lib/google/readme_moodle.txt, please.
226 * profile_display_badges() has been deprecated. See MDL-48935 for details.
227 * 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"
228 then please use this function to ensure that the breadcrumb and navigation block are created properly for all user profile pages.
229 * process_new_icon() now does not always return a PNG file. When possible, it will try to keep the format of the original file.
230 Set the new argument $preferpng to true to force PNG. See MDL-46763 and MDL-50041 for details.
234 * Gradebook grade category option "aggregatesubcats" has been removed completely.
235 This means that the database column is removed, the admin settings are removed and
236 the properties from the grade_category object have been removed. If any courses were
237 found to be using this setting, a warning to check the grades will be shown in the
238 course grader report after upgrading the site. The same warning will be shown on
239 courses restored from backup that had this setting enabled (see MDL-47503).
240 * lib/excelllib.class.php has been updated. The class MoodleExcelWorkbook will now only produce excel 2007 files.
241 * renderers: We now remove the suffix _renderable when looking for a render method for a renderable.
242 If you have a renderable class named like "blah_renderable" and have a method on a renderer named "render_blah_renderable"
243 you will need to change the name of your render method to "render_blah" instead, as renderable at the end is no longer accepted.
244 * New functions get_course_and_cm_from_cmid($cmorid, $modulename) and
245 get_course_and_cm_from_instance($instanceorid, $modulename) can be used to
246 more efficiently load these basic data objects at the start of a script.
247 * New function cm_info::create($cm) can be used when you need a cm_info
248 object, but have a $cm which might only be a standard database record.
249 * $CFG->enablegroupmembersonly no longer exists.
250 * Scheduled tasks have gained support for syntax to introduce variability when a
251 task will run across installs. When a when hour or minute are defined as 'R'
252 they will be installed with a random hour/minute value.
253 * Several classes grade_edit_tree_column_xxx were removed since grades setup page
254 has been significantly changed. These classes should not be used outside of
255 gradebook or developers can copy them into their plugins from 2.7 branch.
256 * Google APIs Client Library (lib/google/) has been upgraded to 1.0.5-beta and
257 API has changed dramatically without backward compatibility. Any code accessing
258 it must be amended. It does not apply to lib/googleapi.php. See MDL-47297
259 * Added an extra parameter to the function get_formatted_help_string() (default null) which is used to specify
260 additional string parameters.
261 * User settings node and course node in navigation now support callbacks from admin tools.
262 * grade_get_grades() optional parameteres $itemtype, $itemmodule, $iteminstance are now required.
265 * completion_info->get_incomplete_criteria() is deprecated and will be removed in Moodle 3.0.
266 * grade_category::aggregate_values() is deprecated and will be removed in Moodle 3.0.
267 * groups_filter_users_by_course_module_visible() is deprecated; replace with
268 core_availability\info::filter_user_list. Will be removed in Moodle 3.0.
269 * groups_course_module_visible() is deprecated; replace with $cm->uservisible.
270 * cm_info property $cm->groupmembersonly is deprecated and always returns 0.
271 Use core_availability\info::filter_user_list if trying to determine which
272 other users can see an activity.
273 * cm_info method $cm->is_user_access_restricted_by_group() is deprecated and
274 always returns false. Use $cm->uservisible to determine whether the user can
276 * Constant FEATURE_GROUPMEMBERSONLY (used in module _supports functions) is
278 * cohort_get_visible_list() is deprecated. There is a better function cohort_get_available_cohorts()
279 that respects user capabilities to view cohorts.
280 * enrol_cohort_get_cohorts() and enrol_cohort_search_cohorts() are deprecated since
281 functionality is removed. Please use cohort_get_available_cohorts()
282 * enrol_cohort_enrol_all_users() is deprecated; enrol_manual is now responsible for this action
283 * enrol_cohort_can_view_cohort() is deprecated; replace with cohort_can_view_cohort()
285 === 2.6.4 / 2.7.1 ===
287 * setnew_password_and_mail() and update_internal_user_password() will trigger
288 \core\event\user_password_updated. Previously they used to generate
289 \core\event\user_updated event.
290 * update_internal_user_password() accepts optional boolean $fasthash for fast
292 * user_update_user() and user_create_user() api's accept optional param
293 $triggerevent to avoid respective events to be triggred from the api's.
297 * PHPUnit cannot be installed via PEAR any more, please use composer package manager instead.
298 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
301 * Significant changes in Logging API. For upgrading existing events_trigger() and
302 add_to_log() see http://docs.moodle.org/dev/Migrating_logging_calls_in_plugins
303 For accessing logs from plugins see http://docs.moodle.org/dev/Migrating_log_access_in_reports

332 * $module uses in mod/xxx/version.php files is now deprecated. Please use $plugin instead. It will be removed in Moodle 2.10.
333 * Update init methods in all event classes - "level" property was renamed to "edulevel", the level property is now deprecated.
334 * Abstract class \core\event\course_module_instances_list_viewed is deprecated now, use \core\event\instances_list_viewed instead.
335 * Abstract class core\event\content_viewed has been deprecated. Please extend base event or other relevant abstract class.
336 * mod_book\event\instances_list_viewed has been deprecated. Please use mod_book\event\course_module_instance_list_viewed instead.
337 * mod_chat\event\instances_list_viewed has been deprecated. Please use mod_chat\event\course_module_instance_list_viewed instead.
338 * mod_choice\event\instances_list_viewed has been deprecated. Please use mod_choice\event\course_module_instance_list_viewed instead.

340 * mod_page\event\instances_list_viewed has been deprecated. Please use mod_page\event\course_module_instance_list_viewed instead.
341 * The constants FRONTPAGECOURSELIST, FRONTPAGETOPICONLY & FRONTPAGECOURSELIMIT have been removed.
342 * Conditional availability API has moved and changed. The condition_info class is
343 replaced by \core_availability\info_module, and condition_info_section by
344 \core_availability\info_section. (Code that uses the old classes will generally
346 * coursemodule_visible_for_user() has been deprecated but still works - replaced
347 by a new static function \core_availability\info_module::is_user_visible()
348 * cm_info::is_user_access_restricted_by_conditional_access has been deprecated
349 but still works (it has never done what its name suggests, and is
351 * cm_info and section_info property showavailability has been deprecated, but
352 still works (with the caveat that this information is now per-user).
353 * cm_info and section_info properties availablefrom and availableuntil have been
354 deprecated and always return zero (underlying data doesn't have these values).
355 * section_info property groupingid has been deprecated and always returns zero,
357 * Various cm_info methods have been deprecated in favour of their read-only properties (get_url(), get_content(), get_extra_classes(),
358 get_on_click(), get_custom_data(), get_after_link, get_after_edit_icons)
359 * The ajaxenabled function has been deprecated and always returns true. All code should be fully functional in Javascript.
360 * count_login_failures() has been deprecated, use user_count_login_failures() instead. Refer MDL-42891 for details.
362 Conditional availability (activities and sections):
363 * New conditional availability API in /availability, including new availability
364 condition plugins in /availability/condition. The new API is very similar with
365 regard to checking availability, but any code that modifies availability settings
366 for an activity or section is likely to need substantial changes.
369 * The lightbox attribute for moodle-core-notification-dialogue has been
370 deprecated and replaced by the modal attribute. This was actually
371 changed in Moodle 2.2, but has only been marked as deprecated now. It
372 will be removed in Moodle 2.9.
373 * When destroying any type of dialogue based on moodle-core-notification, the relevant content is also removed from
374 the DOM. Previously it was left orphaned.
377 * The findChildNodes global function has been deprecated. Y.all should
379 * The callback argument to confirm_action and M.util.show_confirm_dialog has been deprecated. If you need to write a
380 confirmation which includes a callback, please use moodle-core-notification-confirmation and attach callbacks to the
383 * New locking api and admin settings to configure the system locking type.
384 * New "Time spent waiting for the database" performance metric displayed along with the
385 other MDL_PERF vars; the change affects both the error logs and the vars displayed in
387 * Changes in the tag API. The component and contextid are now saved when assigning tags to an item. Please see
388 tag/upgrade.txt for more information.
392 * Use new methods from core_component class instead of get_core_subsystems(), get_plugin_types(),
393 get_plugin_list(), get_plugin_list_with_class(), get_plugin_directory(), normalize_component(),
394 get_component_directory() and get_plugin_list_with_file(). The names of the new methods are
395 exactly the same, the only differences are that core_component::get_plugin_types() now always returns
396 full paths and core_component::get_plugin_list() does not accept empty parameter any more.
397 * Use core_text::* instead of textlib:: and also core_collator::* instead of collatorlib::*.
398 * Use new function moodleform::mock_submit() to simulate form submission in unit tests (backported).
399 * New $CFG->localcachedir setting useful for cluster nodes. Admins have to update X-Sendfile aliases if used.
400 * MS SQL Server drivers are now using NVARCHAR(MAX) instead of NTEXT and VARBINARY(MAX) instead of IMAGE,
401 this change should be fully transparent and it should help significantly with add-on compatibility.
402 * The string manager classes were renamed. Note that they should not be modified or used directly,
403 always use get_string_manager() to get instance of the string manager.
404 * The ability to use an 'insecure' rc4encrypt/rc4decrypt key has been removed.
405 * Use $CFG->debugdeveloper instead of debugging('', DEBUG_DEVELOPER).
406 * Use set_debugging(DEBUG_xxx) when changing debugging level for current request.
407 * Function moveto_module() does not modify $mod argument and instead now returns the new module visibility value.
408 * Use behat_selectors::get_allowed_text_selectors() and behat_selectors::get_allowed_selectors() instead of
409 behat_command::$allowedtextselectors and behat_command::$allowedselectors
410 * Subplugins are supported in admin tools and local plugins.
411 * file_packer/zip_packer API has been modified so that key functions support a new file_progress interface
412 to report progress during long operations. Related to this, zip_archive now supports an estimated_count()
413 function that returns an approximate number of entries in the zip faster than the count() function.
414 * Class cm_info no longer extends stdClass. All properties are read-only and calculated on first request only.
415 * Class course_modinfo no longer extends stdClass. All properties are read-only.
416 * Database fields modinfo and sectioncache in table course are removed. Application cache core/coursemodinfo
417 is used instead. Course cache is still reset, rebuilt and retrieved using function rebuild_course_cache() and
418 get_fast_modinfo(). Purging all caches and every core upgrade purges course modinfo cache as well.
419 If function get_fast_modinfo() is called for multiple courses make sure to include field cacherev in course
421 * Internal (noreply and support) user support has been added for sending/receiving message.
422 Use core_user::get_noreply_user() and core_user::get_support_user() to get noreply and support user's respectively.
423 Real users can be used as noreply/support users by setting $CFG->noreplyuserid and $CFG->supportuserid
424 * New function readfile_allow_large() in filelib.php for use when very large files may need sending to user.
425 * Use core_plugin_manager::reset_caches() when changing visibility of plugins.
426 * Implement new method get_enabled_plugins() method in subplugin info classes.
427 * Each plugin should include version information in version.php.
428 * Module and block tables do not contain version column any more, use get_config('xx_yy', 'version') instead.
429 * $USER->password field is intentionally unset so that session data does not contain password hashes.
430 * Use core_shutdown_manager::register_function() instead of register_shutdown_function().
431 * New file packer for .tar.gz files; obtain by calling get_file_packer('application/x-gzip'). Intended initially
432 for use in backup/restore only, as there are limitations on supported filenames. Also new packer for
433 backups which supports both compression formats; get_file_packer('application/vnd.moodle.backup').
434 * New optional parameter to stored_file::get_content_file_handle to open file handle with 'gzopen' instead
435 of 'fopen' to read gzip-compressed files if required.
436 * update_internal_user_password() and setnew_password_and_mail() now trigger user_updated event.
437 * Add thirdpartylibs.xml file to plugins that bundle any 3rd party libraries.
438 * New class introduced to help auto generate zIndex values for modal dialogues. Class "moodle-has-zindex"
439 should set on any element which uses a non-default zindex and needs to ensure it doesn't show above a
441 * $CFG->filelifetime is now used consistently for most file serving operations, the default was lowered
442 to 6 hours from 24 hours because etags and x-sendfile support should make file serving less expensive.
443 * Date format locale charset for windows server will come from calendar type and for gregorian it will use
445 * The library to interact with Box.net (class boxclient) is only compatible with their APIv1 which
446 reaches its end of life on the 14th of Dec. You should migrate your scripts to make usage of the
447 new class boxnet_client(). Note that the method names and return values have changed.
448 * Settings pages are now possible for Calendar type plugins. Calendar type plugins that require a settings page to
449 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.
450 * The admin/tool/generator tool was overhauled to use testing data generators and the previous interface to create
451 test data was removed (it was not working correctly anyway). If you were using this tool you will probably need to
455 Various previously deprecated functions have now been altered to throw DEBUG_DEVELOPER debugging notices

561 * get_browser_version_classes() -> core_useragent::get_browser_version_classes()
564 * moodle-core-notification has been deprecated with a recommendation of
565 using its subclasses instead. This is to allow for reduced page
566 transport costs. Current subclasses include:
573 Event triggering and event handlers:
574 * All existing events and event handlers should be replaced by new
575 event classes and matching new event observers.
576 * See http://docs.moodle.org/dev/Event_2 for more information.
577 * The following events will be entirely removed, though they can still
578 be captured using handlers, but they should not be used any more.
579 * groups_members_removed -> \core\event\group_member_removed
580 * groups_groupings_groups_removed -> (no replacement)
581 * groups_groups_deleted -> \core\event\group_deleted
582 * groups_groupings_deleted -> \core\event\grouping_deleted
583 * edit_module_post_actions() does not trigger events any more.
587 * New get_course() function for use when obtaining the course record from database. Will
588 reuse existing $COURSE or $SITE globals if possible to improve performance.
592 * The database drivers (moodle_database and subclasses) aren't using anymore the ::columns property
593 for caching database metadata. MUC (databasemeta) is used instead. Any custom DB driver should
594 apply for that change.
595 * The cron output has been changed to include time and memory usage (see cron_trace_time_and_memory()),
596 so any custom utility relying on the old output may require modification.
597 * Function get_max_file_sizes now returns an option for (for example) "Course limit (500MB)" or
598 "Site limit (200MB)" when appropriate with the option set to 0. This function no longer returns
599 an option for 0 bytes. Existing code that was replacing the 0 option in the return
600 from this function with a more sensible message, can now use the return from this function directly.
601 * Functions responsible for output in course/lib.php are deprecated, the code is moved to
602 appropriate renderers: print_section(), print_section_add_menus(), get_print_section_cm_text(),
603 make_editing_buttons()
604 See functions' phpdocs in lib/deprecatedlib.php
605 * Function get_print_section_cm_text() is deprecated, replaced with methods in cm_info
606 * zip_packer may create empty zip archives, there is a new option to ignore
607 problematic files when creating archive
608 * The function delete_course_module was deprecated and has been replaced with
609 course_delete_module. The reason for this was because the function delete_course_module
610 only partially deletes data, so wherever it was called extra code was needed to
611 perform the whole deletion process. The function course_delete_module now takes care
612 of the whole process.
613 * curl::setopt() does not accept constant values any more. As it never worked properly,
614 we decided to make the type check stricter. Now, the keys of the array pass must be a string
615 corresponding to the curl constant name.
616 * Function get_users_listing now return list of users except guest and deleted users. Previously
617 deleted users were excluded by get_users_listing. As guest user is not expected while browsing users,
618 and not included in get_user function, it will not be returned by get_users_listing.
619 * The add_* functions in course/dnduploadlib.php have been deprecated. Plugins should be using the
620 MODNAME_dndupload_register callback instead.
621 * The signature of the add() method of classes implementing the parentable_part_of_admin_tree
622 interface (such as admin_category) has been extended. The new parameter allows the caller
623 to prepend the new node before an existing sibling in the admin tree.
624 * condition_info:get_condition_user_fields($formatoptions) now accepts the optional
625 param $formatoptions, that will determine if the field names are processed by
626 format_string() with the passed options.
627 * remove all references to $CFG->gdversion, GD PHP extension is now required
628 * Formslib will now throw a developer warning if a PARAM_ type hasn't been set for elements which
629 need it. Please set PARAM_RAW explicitly if you do not want any cleaning.
630 * Functions responsible for managing and accessing course categories are moved to class coursecat
631 in lib/coursecatlib.php, functions responsible for rendering courses and categories lists are
632 moved to course/renderer.php. The following global functions are deprecated: make_categories_list(),
633 category_delete_move(), category_delete_full(), move_category(), course_category_hide(),
634 course_category_show(), get_course_category(), create_course_category(), get_all_subcategories(),
635 get_child_categories(), get_categories(), print_my_moodle(), print_remote_course(),
636 print_remote_host(), print_whole_category_list(), print_category_info(), get_course_category_tree(),
637 print_courses(), print_course(), get_category_courses_array(), get_category_courses_array_recursively(),
638 get_courses_wmanagers()
639 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
640 * $core_renderer->block_move_target() changed to support more verbose move-block-here descriptions.
641 * Additional (optional) param $onlyactive has been added to get_enrolled_users, count_enrolled_users
642 functions to get information for only active (excluding suspended enrolments) users. Included two
643 helper functions extract_suspended_users, get_suspended_userids to extract suspended user information.
644 * The core_plugin_manager class now provides two new helper methods for getting information
645 about known plugins: get_plugins_of_type() and get_subplugins_of_plugin().
646 * The get_uninstall_url() method of all subclasses of \core\plugininfo\base class is now expected
647 to always return moodle_url. Subclasses can use the new method is_uninstall_allowed()
648 to control the availability of the 'Uninstall' link at the Plugins overview page (previously
649 they would do it by get_uninstall_url() returning null). By default, URL to a new general plugin
650 uninstall tool is returned. Unless the plugin type needs extra steps that can't be handled by
651 plugininfo_xxx::uninstall() method or xmldb_xxx_uninstall() function, this default URL should
652 satisfy all plugin types.
654 Database (DML) layer:
655 * $DB->sql_empty() is deprecated, you have to use sql parameters with empty values instead,
656 please note hardcoding of empty strings in SQL queries breaks execution in Oracle database.
657 * Indexes must not be defined on the same columns as keys, this is now reported as fatal problem.
658 Please note that internally we create indexes instead of foreign keys.
661 * M.util.help_icon has been deprecated. Code should be updated to use moodle-core-popuphelp
662 instead. To do so, remove any existing JS calls to M.util.help_icon from your PHP and ensure
663 that your help link is placed in a span which has the class 'helplink'.
667 * Pagelib: Numerous deprecated functions were removed as classes page_base, page_course
668 and page_generic_activity.
669 * use $CFG->googlemapkey3 instead of removed $CFG->googlemapkey and migrate to Google Maps API V3
670 * Function settings_navigation::add_course_editing_links() is completely removed
671 * function global_navigation::format_display_course_content() is removed completely (the
672 functionality is moved to course format class)
673 * in the function global_navigation::load_generic_course_sections() the argument $courseformat is
675 * New component and itemid columns in groups_members table - this allows plugin to create protected
676 group memberships using 'xx_yy_allow_group_member_remove' callback and there is also a new restore
677 callback 'xx_yy_restore_group_member()'.
678 * New general role assignment restore plugin callback 'xx_yy_restore_role_assignment()'.
679 * functions get_generic_section_name(), get_all_sections(), add_mod_to_section(), get_all_mods()
680 are deprecated. See their phpdocs in lib/deprecatedlib.php on how to replace them
683 * moodle-enrol-notification has been renamed to moodle-core-notification
684 * YUI2 code must now use 2in3, see http://yuilibrary.com/yui/docs/yui/yui-yui2.html
685 * M.util.init_select_autosubmit() and M.util.init_url_select() have been deprecated. Code using this should be updated
686 to use moodle-core-formautosubmit
688 Unit testing changes:
689 * output debugging() is not sent to standard output any more,
690 use $this->assertDebuggingCalled(), $this->assertDebuggingNotCalled(),
691 $this->getDebuggingMessages() or $this->assertResetDebugging() instead.
695 Database layer changes:
696 * objects are not allowed in paramters of DML functions, use explicit casting to strings if necessary
699 * DDL and DML methods which were deprecated in 2.0 have now been removed, they will no longer produce
700 debug messages and will produce fatal errors
704 * send_stored_file() has changed its interface
705 * deleted several resourcelib_embed_* functions from resourcelib.php
709 removed unused libraries:
710 * odbc, base32, CodeSniffer, overlib, apd profiling, kses, Smarty, PEAR Console, swfobject, cssshover.htc, md5.js
713 * new admin/tool plugin type
714 * new context API - old API is still available
715 * deleted users do not have context any more
716 * removed global search
722 * basic suport for restore from 1.9
