1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.0, unknown release date
13 # Autoload support added. Internal require_once's removed in favor of an
14 explicit require list or autoloading. To use HTML Purifier,
15 you must now either use HTMLPurifier.auto.php
16 or HTMLPurifier.includes.php; setting the include path and including
17 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
18 as well to register our autoload handler (or modify your autoload function
19 to check HTMLPurifier_Bootstrap::getPath($class)).
20 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
21 information is stored in the ConfigSchema directory, and the
22 maintenance/generate-schema-cache.php generates the schema.ser file, which
23 is now instantiated. Support for userland schema changes coming soon!
24 ! Extra utility classes for testing and non-library operations can
25 be found in extras/. Specifically, these are FSTools and ConfigSchema.
26 You may find a use for these in your own project, but right now they
27 are highly experimental and volatile.
28 ! Integration with PHPT allows for automated smoketests
29 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
30 by Chris. You can enable them with %HTML.Proprietary if your client
32 ! Support for !important CSS cascade modifier. By default, this will be stripped
33 from CSS, but you can enable it using %CSS.AllowImportant
34 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
36 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
37 Developer error (not enduser error) can cause these to be triggered.
38 - Autoclose now operates iteratively, i.e. <span><span><div> now has
39 both span tags closed.
40 - Various HTMLPurifier_Config convenience functions now accept another parameter
41 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
43 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
44 - Fix bug in ExtractStyleBlocks with comments in style tags
45 - Fix bug in comment parsing for DirectLex
46 . Plugins now get their own changelogs according to project conventions.
47 . Convert tokens to use instanceof, reducing memory footprint and
48 improving comparison speed.
49 . Dry runs now supported in SimpleTest; testing facilities improved
50 . Bootstrap class added for handling autoloading functionality
51 . Implemented recursive glob at FSTools->globr
52 . ConfigSchema now has instance methods for all corresponding define*
54 . A couple of new historical maintenance scripts were added.
55 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
56 . tests/index.php can now be run from any directory.
57 . HTMLPurifier_Token subclasses split into seperate files
58 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
59 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
60 . New --php=php flag added, allows PHP executable to be specified (command
62 . htmlpurifier_add_test() preferred method to translate test files in to
63 classes, because it handles PHPT files too.
64 . Debugger class is deprecated and will be removed soon.
65 . Command line argument parsing for testing scripts revamped, now --opt value
67 . Smoketests now cleanup after magic quotes
68 . Generator now can output comments (however, comments are still stripped
69 from HTML Purifier output)
70 . substr_count PHP4 compatibility cludge removed
72 3.0.0, released 2008-01-06
73 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
74 until PHP 4 is completely deprecated, but no new features will be added
76 + Visibility declarations added
77 + Constructor methods renamed to __construct()
78 + PHP4 reference cruft removed (in progress)
79 ! CSS properties are now case-insensitive
80 ! DefinitionCacheFactory now can register new implementations
81 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
82 documents and cleaning their contents up. Requires the CSSTidy library
83 <http://csstidy.sourceforge.net/>. You can access the blocks with the
84 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
85 The output CSS can also be "scoped" for a specific element, use:
86 %Filter.ExtractStyleBlocksScope
87 ! Experimental support for some proprietary CSS attributes allowed:
88 opacity (and all of the browser-specific equivalents) and scrollbar colors.
89 Enable by setting %CSS.Proprietary to true.
90 - Colors missing # but in hex form will be corrected
91 - CSS Number algorithm improved
92 - Unit testing and multi-testing now on steroids: command lines,
93 XML output, and other goodies now added.
94 . Unit tests for Injector improved
96 + HTMLPurifier_AttrDef_CSS_AlphaValue
97 + HTMLPurifier_AttrDef_CSS_Filter
98 . Multitest now has a file docblock
100 2.1.3, released 2007-11-05
101 ! tests/multitest.php allows you to test multiple versions by running
102 tests/index.php through multiple interpreters using `phpv` shell
103 script (you must provide this script!)
104 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
106 - Injector algorithm further refined: off-by-one error regarding skip
107 counts for dormant injectors fixed
108 - Corrective blockquote definition now enabled for HTML 4.01 Strict
109 - Fatal error when <img> tag (or any other element with required attributes)
110 has 'id' attribute fixed, thanks NykO18 for reporting
111 - Fix warning emitted when a non-supported URI scheme is passed to the
112 MakeAbsolute URIFilter, thanks NykO18 (again)
113 - Further refine AutoParagraph injector. Behavior inside of elements
114 allowing paragraph tags clarified: only inline content delimeted by
115 double newlines (not block elements) are paragraphed.
116 - Buggy treatment of end tags of elements that have required attributes
117 fixed (does not manifest on default tag-set)
118 - Spurious internal content reorganization error suppressed
119 - HTMLDefinition->addElement now returns a reference to the created
120 element object, as implied by the documentation
121 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
122 - Fix a theoretical class of infinite loops from DirectLex reported
124 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
126 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
127 HTMLDefinition errors, this may indicate problems with error-collecting
129 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
130 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
131 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
132 to better communicate its purpose
133 . Error unit tests can now specify the expectation of no errors. Future
134 iterations of the harness will be extremely strict about what errors
136 . Extend Injector hooks to allow for more powerful injector routines
137 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
139 . Doxygen configuration file updated, with minor improvements
140 . Test runner now checks for similarly named files in conf/ directory too.
141 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
143 . Maintenance script for generating PH5P patch added, original PH5P source
144 file also added under version control
145 . Full unit test runner script title made more descriptive with PHP version
146 . Updated INSTALL file to state that 4.3.7 is the earliest version we
149 2.1.2, released 2007-09-03
150 ! Implemented Object module for trusted users
151 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
153 require_once 'HTMLPurifier/Lexer/PH5P.php';
154 $config->set('Core', 'LexerImpl', 'PH5P');
155 Note that this Lexer introduces some classes not in the HTMLPurifier
156 namespace. Also, this is PHP5 only.
157 ! CSS property border-spacing implemented
158 - Fix non-visible parsing error in DirectLex with empty tags that have
159 slashes inside attribute values.
160 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
161 accepted as valid CSS. Usually non-visible, because this styling is the
162 default for tables in most browsers. Thanks Brett Zamir for pointing
164 - Fix validation errors in configuration form
165 - Hammer out a bunch of edge-case bugs in the standalone distribution
166 - Inclusion reflection removed from URISchemeRegistry; you must manually
167 include any new schema files you wish to use
168 - Numerous typo fixes in documentation thanks to Brett Zamir
169 . Unit test refactoring for one logical test per test function
170 . Config and context parameters in ComplexHarness deprecated: instead, edit
171 the $config and $context member variables
172 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
173 really make a difference, but is good for completeness sake
174 . merge-library.php script refactored for greater code reusability and
177 2.1.1, released 2007-08-04
178 - Fix show-stopper bug in %URI.MakeAbsolute functionality
179 - Fix PHP4 syntax error in standalone version
180 . Add prefix directory to include path for standalone, this prevents
181 other installations from clobbering the standalone's URI schemes
182 . Single test methods can be invoked by prefixing with __only
184 2.1.0, released 2007-08-02
185 # flush-htmldefinition-cache.php superseded in favor of a generic
186 flush-definition-cache.php script, you can clear a specific cache
187 by passing its name as a parameter to the script
188 ! Phorum mod implemented for HTML Purifier
189 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
190 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
191 for PHP4 (DirectLex).
192 ! Standalone file now available, which greatly reduces the amount of
193 includes (although there are still a few files that reside in the
195 ! Relative URIs can now be transformed into their absolute equivalents
196 using %URI.Base and %URI.MakeAbsolute
197 ! Ruby implemented for XHTML 1.1
198 ! You can now define custom URI filtering behavior, see enduser-uri-filter.html
200 ! UTF-8 font names now supported in CSS
201 - AutoFormatters emit friendly error messages if tags or attributes they
203 - ConfigForm's compactification of directive names is now configurable
204 - AutoParagraph autoformatter algorithm refined after field-testing
205 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
207 - Contents of <style> tags removed by default when tags are removed
208 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
209 for output cache invalidation
210 . ConfigForm printer now can retrieve CSS and JS files as strings, in
211 case HTML Purifier's directory is not publically accessible
212 . Introduce new text/itext configuration directive values: these represent
213 longer strings that would be more appropriately edited with a textarea
214 . Allow newlines to act as separators for lists, hashes, lookups and
216 . ConfigForm generates textareas instead of text inputs for lists, hashes,
217 lookups, text and itext fields
218 . Hidden element content removal genericized: %Core.HiddenElements can
219 be used to customize this behavior, by default <script> and <style> are
221 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
222 . Custom ChildDef added to default include list
223 . URIScheme reflection improved: will not attempt to include file if class
224 already exists. May clobber autoload, so I need to keep an eye on it
225 . ConfigSchema heavily optimized, will only collect information and validate
226 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
227 . AttrDef_URI unit tests and implementation refactored
228 . benchmarks/ directory now protected from public view with .htaccess file;
229 run the tests via command line
230 . URI scheme is munged off if there is no authority and the scheme is the
232 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
233 . Interface for URIScheme changed
234 . Generic URI object to hold components of URI added, most systems involved
235 in URI validation have been migrated to use it
236 . Custom filtering for URIs factored out to URIDefinition interface for
237 maximum extensibility
239 2.0.1, released 2007-06-27
240 ! Tag auto-closing now based on a ChildDef heuristic rather than a
241 manually set auto_close array; some behavior may change
242 ! Experimental AutoFormat functionality added: auto-paragraph and
243 linkify your HTML input by setting %AutoFormat.AutoParagraph and
244 %AutoFormat.Linkify to true
245 ! Newlines normalized internally, and then converted back to the
246 value of PHP_EOL. If this is not desired, set your newline format
247 using %Output.Newline.
248 ! Beta error collection, messages are implemented for the most generic
249 cases involving Lexing or Strategies
250 - Clean up special case code for <script> tags
251 - Reorder includes for DefinitionCache decorators, fixes a possible
253 - Fixed bug where manually modified definitions were not saved via cache

265 . Rewire some test-cases to swallow errors rather than expect them
266 . HTMLDefinition printer updated with some of the new attributes
267 . DefinitionCache keys reordered to reflect precedence: version number,
268 hash, then revision number
269 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
270 . Interlinking in configuration documentation added using
271 Injector_PurifierLinkify
272 . Directives now keep track of aliases to themselves
273 . Error collector now requires a severity to be passed, use PHP's internal
274 error constants for this
275 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
276 much easier selective embedding of configuration values
277 . Doctype objects now accept public and system DTD identifiers
278 . %HTML.Doctype is now constrained by specific values, to specify a custom
279 doctype use new %HTML.CustomDoctype
280 . ConfigForm truncates long directives to keep the form small, and does
281 not re-output namespaces
283 2.0.0, released 2007-06-20
284 # Completely refactored HTMLModuleManager, decentralizing safety
286 # Transform modules changed to Tidy modules, which offer more flexibility
287 and better modularization
288 # Configuration object now finalizes itself when a read operation is
289 performed on it, ensuring that its internal state stays consistent.
290 To revert this behavior, you can set the $autoFinalize member variable
291 off, but it's not recommended.
292 # New compact syntax for AttrDef objects that can be used to instantiate
293 new objects via make()
294 # Definitions (esp. HTMLDefinition) are now cached for a significant
295 performance boost. You can disable caching by setting %Core.DefinitionCache
296 to null. You CANNOT edit raw definitions without setting the corresponding
297 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
298 # Contents between <script> tags are now completely removed if <script>
300 # Prototype-declarations for Lexer removed in favor of configuration

352 images will hang around with an empty src
353 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
355 ! CSS property white-space now allows nowrap (supported in all modern

358 lang is now moved over to xml:lang.
359 ! Attribute transformation smoketest available at smoketests/attrTransform.php
360 ! Transformation of font's size attribute now handles super-large numbers
361 - Possibly fatal bug with __autoload() fixed in module manager
362 - Invert HTMLModuleManager->addModule() processing order to check

386 %Attr.IDBlacklistRegexp
387 - Error messages are emitted when you attempt to "allow" elements or
388 attributes that HTML Purifier does not support
