1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.1, unknown release date
13 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength.
14 - Disable percent height/width attributes for img
15 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
16 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
18 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
19 to __construct($min, $max). __construct(true) is equivalent to
21 . Added HTMLPurifier_AttrDef_Switch class
23 3.1.0, released 2008-05-18
24 # Unnecessary references to objects (vestiges of PHP4) removed from method
25 signatures. The following methods do not need references when assigning from
26 them and will result in E_STRICT errors if you try:
27 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
28 + HTMLPurifier_ConfigSchema::instance()
29 + HTMLPurifier_DefinitionCacheFactory::instance()
30 + HTMLPurifier_DefinitionCacheFactory->create()
31 + HTMLPurifier_DoctypeRegistry->register()
32 + HTMLPurifier_DoctypeRegistry->get()
33 + HTMLPurifier_HTMLModule->addElement()
34 + HTMLPurifier_HTMLModule->addBlankElement()
35 + HTMLPurifier_LanguageFactory::instance()
36 # Printer_ConfigForm's get*() functions were static-ified
37 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
38 form of tag@attr, NOT tag.attr (which will throw an error and won't do
39 anything). This is for forwards compatibility with XML; you'd do best
40 to migrate an %HTML.AllowedAttributes directives to this syntax too.
41 ! Allow index to be false for config from form creation
42 ! Added HTMLPurifier::VERSION constant
43 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
44 and allows for version numbers like "3.1.0-dev".
45 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
46 ! HTML Purifier's URI handling is a lot more robust, with much stricter
47 validation checks and better percent encoding handling.
48 ! Bootstrap autoloader deals more robustly with classes that don't exist,
49 preventing class_exists($class, true) from barfing.
50 - InterchangeBuilder now alphabetizes its lists
51 - Validation error in configdoc output fixed
52 - Iconv and other encoding errors muted even with custom error handlers that
53 do not honor error_reporting
54 - Add protection against imagecrash attack with CSS height/width
55 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
56 - Fixed and revamped broken ConfigForm smoketest
57 - Bug with bool/null fields in Printer_ConfigForm fixed
58 - Bug with global forbidden attributes fixed
59 - Improved error messages for allowed and forbidden HTML elements and attributes
60 - Missing (or null) in configdoc documentation restored
61 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
62 of DOM), HTML Purifier punts to DirectLex
63 - Fatal error with unserialization of ScriptRequired
64 - Created directories are now chmod'ed properly
65 - Fixed bug with fallback languages in LanguageFactory
66 - Standalone testing setup properly with autoload
67 . Out-of-date documentation revised
68 . UTF-8 encoding check optimization as suggested by Diego
69 . HTMLPurifier_Error removed in favor of exceptions
70 . More copy() function removed; should use clone instead
71 . More extensive unit tests for HTMLDefinition
72 . assertPurification moved to central harness
73 . HTMLPurifier_Generator accepts $config and $context parameters during
74 instantiation, not runtime
75 . Double-quotes outside of attribute values are now unescaped
77 3.1.0rc1, released 2008-04-22
78 # Autoload support added. Internal require_once's removed in favor of an
79 explicit require list or autoloading. To use HTML Purifier,
80 you must now either use HTMLPurifier.auto.php
81 or HTMLPurifier.includes.php; setting the include path and including
82 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
83 as well to register our autoload handler (or modify your autoload function
84 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
85 HTMLPurifier.safe-includes.php for a less performance friendly but more
86 user-friendly library load.
87 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
88 information is stored in the ConfigSchema directory, and the
89 maintenance/generate-schema-cache.php generates the schema.ser file, which
90 is now instantiated. Support for userland schema changes coming soon!
91 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
92 alias; to get rid of these errors just modify your configuration to use
93 the new directive name.
94 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
95 enabled using %Filter.$filter_name or by setting your own filters using
97 # Directive-level safety properties superceded in favor of module-level
98 safety. Internal method HTMLModule->addElement() has changed, although
99 the externally visible HTMLDefinition->addElement has *not* changed.
100 ! Extra utility classes for testing and non-library operations can
101 be found in extras/. Specifically, these are FSTools and ConfigDoc.
102 You may find a use for these in your own project, but right now they
103 are highly experimental and volatile.
104 ! Integration with PHPT allows for automated smoketests
105 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
106 by Chris. You can enable them with %HTML.Proprietary if your client
108 ! Support for !important CSS cascade modifier. By default, this will be stripped
109 from CSS, but you can enable it using %CSS.AllowImportant
110 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
112 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
113 Developer error (not enduser error) can cause these to be triggered.
114 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
115 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
116 mucking around with HTMLPurifier_CSSDefinition
117 ! ConfigDoc output has been enhanced with version and deprecation info.
118 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
119 - Autoclose now operates iteratively, i.e. <span><span><div> now has
120 both span tags closed.
121 - Various HTMLPurifier_Config convenience functions now accept another parameter
122 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
124 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
125 - Fix bug in ExtractStyleBlocks with comments in style tags
126 - Fix bug in comment parsing for DirectLex
127 - Flush output now displayed when in command line mode for unit tester
128 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
129 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
130 on the same element without emitting errors.
131 - Fixed fatal error in PH5P lexer with invalid tag names
132 . Plugins now get their own changelogs according to project conventions.
133 . Convert tokens to use instanceof, reducing memory footprint and
134 improving comparison speed.
135 . Dry runs now supported in SimpleTest; testing facilities improved
136 . Bootstrap class added for handling autoloading functionality
137 . Implemented recursive glob at FSTools->globr
138 . ConfigSchema now has instance methods for all corresponding define*
140 . A couple of new historical maintenance scripts were added.

145 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
146 . New --php=php flag added, allows PHP executable to be specified (command
148 . htmlpurifier_add_test() preferred method to translate test files in to
149 classes, because it handles PHPT files too.
150 . Debugger class is deprecated and will be removed soon.
151 . Command line argument parsing for testing scripts revamped, now --opt value
153 . Smoketests now cleanup after magic quotes
154 . Generator now can output comments (however, comments are still stripped
155 from HTML Purifier output)
156 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
157 HTMLPurifier_VarParser->parse()
158 . Integers auto-cast into float type by VarParser.
159 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
160 during cache generation
161 . Reordered script calls in maintenance/flush.php
162 . Command line scripts now honor exit codes
163 . When --flush fails in unit testers, abort tests and print message
164 . Improved documentation in docs/dev-flush.html about the maintenance scripts
165 . copy() methods removed in favor of clone keyword
167 3.0.0, released 2008-01-06
168 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
169 until PHP 4 is completely deprecated, but no new features will be added
171 + Visibility declarations added
172 + Constructor methods renamed to __construct()
173 + PHP4 reference cruft removed (in progress)
174 ! CSS properties are now case-insensitive

177 documents and cleaning their contents up. Requires the CSSTidy library
178 <http://csstidy.sourceforge.net/>. You can access the blocks with the
179 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
180 The output CSS can also be "scoped" for a specific element, use:
181 %Filter.ExtractStyleBlocksScope
182 ! Experimental support for some proprietary CSS attributes allowed:
183 opacity (and all of the browser-specific equivalents) and scrollbar colors.
184 Enable by setting %CSS.Proprietary to true.
185 - Colors missing # but in hex form will be corrected
186 - CSS Number algorithm improved
187 - Unit testing and multi-testing now on steroids: command lines,

189 . Unit tests for Injector improved
191 + HTMLPurifier_AttrDef_CSS_AlphaValue
192 + HTMLPurifier_AttrDef_CSS_Filter
193 . Multitest now has a file docblock
195 2.1.3, released 2007-11-05
196 ! tests/multitest.php allows you to test multiple versions by running
197 tests/index.php through multiple interpreters using `phpv` shell
198 script (you must provide this script!)
199 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
201 - Injector algorithm further refined: off-by-one error regarding skip
202 counts for dormant injectors fixed
203 - Corrective blockquote definition now enabled for HTML 4.01 Strict
204 - Fatal error when <img> tag (or any other element with required attributes)
205 has 'id' attribute fixed, thanks NykO18 for reporting
206 - Fix warning emitted when a non-supported URI scheme is passed to the
207 MakeAbsolute URIFilter, thanks NykO18 (again)
208 - Further refine AutoParagraph injector. Behavior inside of elements
209 allowing paragraph tags clarified: only inline content delimeted by
210 double newlines (not block elements) are paragraphed.
211 - Buggy treatment of end tags of elements that have required attributes
212 fixed (does not manifest on default tag-set)
213 - Spurious internal content reorganization error suppressed
214 - HTMLDefinition->addElement now returns a reference to the created
215 element object, as implied by the documentation
216 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
217 - Fix a theoretical class of infinite loops from DirectLex reported
219 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
221 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
222 HTMLDefinition errors, this may indicate problems with error-collecting
224 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
225 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
226 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
227 to better communicate its purpose
228 . Error unit tests can now specify the expectation of no errors. Future
229 iterations of the harness will be extremely strict about what errors
231 . Extend Injector hooks to allow for more powerful injector routines
232 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
234 . Doxygen configuration file updated, with minor improvements
235 . Test runner now checks for similarly named files in conf/ directory too.
236 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
238 . Maintenance script for generating PH5P patch added, original PH5P source
239 file also added under version control
240 . Full unit test runner script title made more descriptive with PHP version
241 . Updated INSTALL file to state that 4.3.7 is the earliest version we
244 2.1.2, released 2007-09-03
245 ! Implemented Object module for trusted users
246 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
248 require_once 'HTMLPurifier/Lexer/PH5P.php';
249 $config->set('Core', 'LexerImpl', 'PH5P');
250 Note that this Lexer introduces some classes not in the HTMLPurifier
251 namespace. Also, this is PHP5 only.
252 ! CSS property border-spacing implemented
253 - Fix non-visible parsing error in DirectLex with empty tags that have
254 slashes inside attribute values.
255 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
256 accepted as valid CSS. Usually non-visible, because this styling is the
257 default for tables in most browsers. Thanks Brett Zamir for pointing
259 - Fix validation errors in configuration form
260 - Hammer out a bunch of edge-case bugs in the standalone distribution
261 - Inclusion reflection removed from URISchemeRegistry; you must manually
262 include any new schema files you wish to use
263 - Numerous typo fixes in documentation thanks to Brett Zamir
264 . Unit test refactoring for one logical test per test function
265 . Config and context parameters in ComplexHarness deprecated: instead, edit
266 the $config and $context member variables
267 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
268 really make a difference, but is good for completeness sake
269 . merge-library.php script refactored for greater code reusability and
272 2.1.1, released 2007-08-04
273 - Fix show-stopper bug in %URI.MakeAbsolute functionality
274 - Fix PHP4 syntax error in standalone version
275 . Add prefix directory to include path for standalone, this prevents
276 other installations from clobbering the standalone's URI schemes
277 . Single test methods can be invoked by prefixing with __only
279 2.1.0, released 2007-08-02
280 # flush-htmldefinition-cache.php superseded in favor of a generic
281 flush-definition-cache.php script, you can clear a specific cache
282 by passing its name as a parameter to the script
283 ! Phorum mod implemented for HTML Purifier
284 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
285 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
286 for PHP4 (DirectLex).
287 ! Standalone file now available, which greatly reduces the amount of
288 includes (although there are still a few files that reside in the
290 ! Relative URIs can now be transformed into their absolute equivalents
291 using %URI.Base and %URI.MakeAbsolute

303 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
304 for output cache invalidation
305 . ConfigForm printer now can retrieve CSS and JS files as strings, in
306 case HTML Purifier's directory is not publically accessible
307 . Introduce new text/itext configuration directive values: these represent
308 longer strings that would be more appropriately edited with a textarea
309 . Allow newlines to act as separators for lists, hashes, lookups and
311 . ConfigForm generates textareas instead of text inputs for lists, hashes,
312 lookups, text and itext fields
313 . Hidden element content removal genericized: %Core.HiddenElements can
314 be used to customize this behavior, by default <script> and <style> are
316 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
317 . Custom ChildDef added to default include list
318 . URIScheme reflection improved: will not attempt to include file if class
319 already exists. May clobber autoload, so I need to keep an eye on it
320 . ConfigSchema heavily optimized, will only collect information and validate
321 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
322 . AttrDef_URI unit tests and implementation refactored
323 . benchmarks/ directory now protected from public view with .htaccess file;
324 run the tests via command line

327 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
328 . Interface for URIScheme changed
329 . Generic URI object to hold components of URI added, most systems involved
330 in URI validation have been migrated to use it
331 . Custom filtering for URIs factored out to URIDefinition interface for
332 maximum extensibility
334 2.0.1, released 2007-06-27
335 ! Tag auto-closing now based on a ChildDef heuristic rather than a
336 manually set auto_close array; some behavior may change
337 ! Experimental AutoFormat functionality added: auto-paragraph and
338 linkify your HTML input by setting %AutoFormat.AutoParagraph and
339 %AutoFormat.Linkify to true
340 ! Newlines normalized internally, and then converted back to the
341 value of PHP_EOL. If this is not desired, set your newline format
342 using %Output.Newline.
343 ! Beta error collection, messages are implemented for the most generic
344 cases involving Lexing or Strategies
345 - Clean up special case code for <script> tags
346 - Reorder includes for DefinitionCache decorators, fixes a possible
348 - Fixed bug where manually modified definitions were not saved via cache
349 (mostly harmless, except for the fact that it would be a little slower)
350 - Configuration objects with different serials do not clobber each
351 others when revision numbers are unequal
352 - Improve Serializer DefinitionCache directory permissions checks

363 hash, then revision number
364 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
365 . Interlinking in configuration documentation added using
366 Injector_PurifierLinkify
367 . Directives now keep track of aliases to themselves
368 . Error collector now requires a severity to be passed, use PHP's internal
369 error constants for this
370 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
371 much easier selective embedding of configuration values
372 . Doctype objects now accept public and system DTD identifiers
373 . %HTML.Doctype is now constrained by specific values, to specify a custom
374 doctype use new %HTML.CustomDoctype
375 . ConfigForm truncates long directives to keep the form small, and does
376 not re-output namespaces
378 2.0.0, released 2007-06-20
379 # Completely refactored HTMLModuleManager, decentralizing safety
381 # Transform modules changed to Tidy modules, which offer more flexibility
382 and better modularization
383 # Configuration object now finalizes itself when a read operation is
384 performed on it, ensuring that its internal state stays consistent.
385 To revert this behavior, you can set the $autoFinalize member variable
386 off, but it's not recommended.
387 # New compact syntax for AttrDef objects that can be used to instantiate
388 new objects via make()
389 # Definitions (esp. HTMLDefinition) are now cached for a significant
390 performance boost. You can disable caching by setting %Core.DefinitionCache
391 to null. You CANNOT edit raw definitions without setting the corresponding
392 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
393 # Contents between <script> tags are now completely removed if <script>
395 # Prototype-declarations for Lexer removed in favor of configuration

411 - DOMLex will not emit errors when a custom error handler that does not
412 honor error_reporting is used
413 - StrictBlockquote child definition refrains from wrapping whitespace
415 - Bug resulting from tag transforms to non-allowed elements fixed
416 - ChildDef_Custom's regex generation has been improved, removing several
418 . Unit test for ElementDef created, ElementDef behavior modified to
420 . Added convenience functions for HTMLModule constructors
421 . AttrTypes now has accessor functions that should be used instead
422 of directly manipulating info
423 . TagTransform_Center deprecated in favor of generic TagTransform_Simple

447 images will hang around with an empty src
448 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
450 ! CSS property white-space now allows nowrap (supported in all modern
451 browsers) but not others (which have spotty browser implementations)
452 ! XHTML 1.1 mode now sort-of works without any fatal errors, and
453 lang is now moved over to xml:lang.
454 ! Attribute transformation smoketest available at smoketests/attrTransform.php
455 ! Transformation of font's size attribute now handles super-large numbers
456 - Possibly fatal bug with __autoload() fixed in module manager
457 - Invert HTMLModuleManager->addModule() processing order to check

481 %Attr.IDBlacklistRegexp
482 - Error messages are emitted when you attempt to "allow" elements or
483 attributes that HTML Purifier does not support
484 - Fix segfault in unit test. The problem is not very reproduceable and

487 1.5.0, released 2007-03-23
488 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
489 doesn't actually do anything yet, but keep your eyes peeled.
490 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
491 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

512 . Modify Youtube filter regexp to be multiline
513 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
