1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.1, unknown release date
13 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
14 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
17 3.1.0, released 2008-05-18
18 # Unnecessary references to objects (vestiges of PHP4) removed from method
19 signatures. The following methods do not need references when assigning from
20 them and will result in E_STRICT errors if you try:
21 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
22 + HTMLPurifier_ConfigSchema::instance()
23 + HTMLPurifier_DefinitionCacheFactory::instance()
24 + HTMLPurifier_DefinitionCacheFactory->create()
25 + HTMLPurifier_DoctypeRegistry->register()
26 + HTMLPurifier_DoctypeRegistry->get()
27 + HTMLPurifier_HTMLModule->addElement()
28 + HTMLPurifier_HTMLModule->addBlankElement()
29 + HTMLPurifier_LanguageFactory::instance()
30 # Printer_ConfigForm's get*() functions were static-ified
31 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
32 form of tag@attr, NOT tag.attr (which will throw an error and won't do
33 anything). This is for forwards compatibility with XML; you'd do best
34 to migrate an %HTML.AllowedAttributes directives to this syntax too.
35 ! Allow index to be false for config from form creation
36 ! Added HTMLPurifier::VERSION constant
37 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
38 and allows for version numbers like "3.1.0-dev".
39 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
40 ! HTML Purifier's URI handling is a lot more robust, with much stricter
41 validation checks and better percent encoding handling.
42 ! Bootstrap autoloader deals more robustly with classes that don't exist,
43 preventing class_exists($class, true) from barfing.
44 - InterchangeBuilder now alphabetizes its lists
45 - Validation error in configdoc output fixed
46 - Iconv and other encoding errors muted even with custom error handlers that
47 do not honor error_reporting
48 - Add protection against imagecrash attack with CSS height/width
49 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
50 - Fixed and revamped broken ConfigForm smoketest
51 - Bug with bool/null fields in Printer_ConfigForm fixed
52 - Bug with global forbidden attributes fixed
53 - Improved error messages for allowed and forbidden HTML elements and attributes
54 - Missing (or null) in configdoc documentation restored
55 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
56 of DOM), HTML Purifier punts to DirectLex
57 - Fatal error with unserialization of ScriptRequired
58 - Created directories are now chmod'ed properly
59 - Fixed bug with fallback languages in LanguageFactory
60 - Standalone testing setup properly with autoload
61 . Out-of-date documentation revised
62 . UTF-8 encoding check optimization as suggested by Diego
63 . HTMLPurifier_Error removed in favor of exceptions
64 . More copy() function removed; should use clone instead
65 . More extensive unit tests for HTMLDefinition
66 . assertPurification moved to central harness
67 . HTMLPurifier_Generator accepts $config and $context parameters during
68 instantiation, not runtime
69 . Double-quotes outside of attribute values are now unescaped
71 3.1.0rc1, released 2008-04-22
72 # Autoload support added. Internal require_once's removed in favor of an
73 explicit require list or autoloading. To use HTML Purifier,
74 you must now either use HTMLPurifier.auto.php
75 or HTMLPurifier.includes.php; setting the include path and including
76 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
77 as well to register our autoload handler (or modify your autoload function
78 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
79 HTMLPurifier.safe-includes.php for a less performance friendly but more
80 user-friendly library load.
81 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
82 information is stored in the ConfigSchema directory, and the
83 maintenance/generate-schema-cache.php generates the schema.ser file, which
84 is now instantiated. Support for userland schema changes coming soon!
85 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
86 alias; to get rid of these errors just modify your configuration to use
87 the new directive name.
88 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
89 enabled using %Filter.$filter_name or by setting your own filters using
91 # Directive-level safety properties superceded in favor of module-level
92 safety. Internal method HTMLModule->addElement() has changed, although
93 the externally visible HTMLDefinition->addElement has *not* changed.
94 ! Extra utility classes for testing and non-library operations can
95 be found in extras/. Specifically, these are FSTools and ConfigDoc.
96 You may find a use for these in your own project, but right now they
97 are highly experimental and volatile.
98 ! Integration with PHPT allows for automated smoketests
99 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
100 by Chris. You can enable them with %HTML.Proprietary if your client
102 ! Support for !important CSS cascade modifier. By default, this will be stripped
103 from CSS, but you can enable it using %CSS.AllowImportant
104 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
106 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
107 Developer error (not enduser error) can cause these to be triggered.
108 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
109 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
110 mucking around with HTMLPurifier_CSSDefinition
111 ! ConfigDoc output has been enhanced with version and deprecation info.
112 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
113 - Autoclose now operates iteratively, i.e. <span><span><div> now has
114 both span tags closed.
115 - Various HTMLPurifier_Config convenience functions now accept another parameter
116 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
118 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
119 - Fix bug in ExtractStyleBlocks with comments in style tags
120 - Fix bug in comment parsing for DirectLex
121 - Flush output now displayed when in command line mode for unit tester
122 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
123 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
124 on the same element without emitting errors.
125 - Fixed fatal error in PH5P lexer with invalid tag names
126 . Plugins now get their own changelogs according to project conventions.
127 . Convert tokens to use instanceof, reducing memory footprint and
128 improving comparison speed.
129 . Dry runs now supported in SimpleTest; testing facilities improved
130 . Bootstrap class added for handling autoloading functionality
131 . Implemented recursive glob at FSTools->globr
132 . ConfigSchema now has instance methods for all corresponding define*
134 . A couple of new historical maintenance scripts were added.
135 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
136 . tests/index.php can now be run from any directory.
137 . HTMLPurifier_Token subclasses split into seperate files
138 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
139 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
140 . New --php=php flag added, allows PHP executable to be specified (command
142 . htmlpurifier_add_test() preferred method to translate test files in to
143 classes, because it handles PHPT files too.
144 . Debugger class is deprecated and will be removed soon.
145 . Command line argument parsing for testing scripts revamped, now --opt value
147 . Smoketests now cleanup after magic quotes
148 . Generator now can output comments (however, comments are still stripped
149 from HTML Purifier output)
150 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
151 HTMLPurifier_VarParser->parse()
152 . Integers auto-cast into float type by VarParser.
153 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
154 during cache generation
155 . Reordered script calls in maintenance/flush.php
156 . Command line scripts now honor exit codes
157 . When --flush fails in unit testers, abort tests and print message
158 . Improved documentation in docs/dev-flush.html about the maintenance scripts
159 . copy() methods removed in favor of clone keyword
161 3.0.0, released 2008-01-06
162 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
163 until PHP 4 is completely deprecated, but no new features will be added
165 + Visibility declarations added
166 + Constructor methods renamed to __construct()
167 + PHP4 reference cruft removed (in progress)

171 documents and cleaning their contents up. Requires the CSSTidy library
172 <http://csstidy.sourceforge.net/>. You can access the blocks with the
173 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
174 The output CSS can also be "scoped" for a specific element, use:
175 %Filter.ExtractStyleBlocksScope
176 ! Experimental support for some proprietary CSS attributes allowed:
177 opacity (and all of the browser-specific equivalents) and scrollbar colors.
178 Enable by setting %CSS.Proprietary to true.
179 - Colors missing # but in hex form will be corrected
180 - CSS Number algorithm improved
181 - Unit testing and multi-testing now on steroids: command lines,

183 . Unit tests for Injector improved
185 + HTMLPurifier_AttrDef_CSS_AlphaValue
186 + HTMLPurifier_AttrDef_CSS_Filter
187 . Multitest now has a file docblock
189 2.1.3, released 2007-11-05
190 ! tests/multitest.php allows you to test multiple versions by running
191 tests/index.php through multiple interpreters using `phpv` shell
192 script (you must provide this script!)
193 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
195 - Injector algorithm further refined: off-by-one error regarding skip
196 counts for dormant injectors fixed
197 - Corrective blockquote definition now enabled for HTML 4.01 Strict
198 - Fatal error when <img> tag (or any other element with required attributes)
199 has 'id' attribute fixed, thanks NykO18 for reporting
200 - Fix warning emitted when a non-supported URI scheme is passed to the
201 MakeAbsolute URIFilter, thanks NykO18 (again)
202 - Further refine AutoParagraph injector. Behavior inside of elements
203 allowing paragraph tags clarified: only inline content delimeted by
204 double newlines (not block elements) are paragraphed.
205 - Buggy treatment of end tags of elements that have required attributes
206 fixed (does not manifest on default tag-set)
207 - Spurious internal content reorganization error suppressed
208 - HTMLDefinition->addElement now returns a reference to the created
209 element object, as implied by the documentation
210 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
211 - Fix a theoretical class of infinite loops from DirectLex reported
213 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
215 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
216 HTMLDefinition errors, this may indicate problems with error-collecting
218 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
219 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
220 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
221 to better communicate its purpose
222 . Error unit tests can now specify the expectation of no errors. Future
223 iterations of the harness will be extremely strict about what errors
225 . Extend Injector hooks to allow for more powerful injector routines
226 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
228 . Doxygen configuration file updated, with minor improvements
229 . Test runner now checks for similarly named files in conf/ directory too.
230 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
232 . Maintenance script for generating PH5P patch added, original PH5P source
233 file also added under version control
234 . Full unit test runner script title made more descriptive with PHP version
235 . Updated INSTALL file to state that 4.3.7 is the earliest version we
238 2.1.2, released 2007-09-03
239 ! Implemented Object module for trusted users
240 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
242 require_once 'HTMLPurifier/Lexer/PH5P.php';
243 $config->set('Core', 'LexerImpl', 'PH5P');
244 Note that this Lexer introduces some classes not in the HTMLPurifier
245 namespace. Also, this is PHP5 only.
246 ! CSS property border-spacing implemented
247 - Fix non-visible parsing error in DirectLex with empty tags that have
248 slashes inside attribute values.
249 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
250 accepted as valid CSS. Usually non-visible, because this styling is the
251 default for tables in most browsers. Thanks Brett Zamir for pointing
253 - Fix validation errors in configuration form
254 - Hammer out a bunch of edge-case bugs in the standalone distribution
255 - Inclusion reflection removed from URISchemeRegistry; you must manually
256 include any new schema files you wish to use
257 - Numerous typo fixes in documentation thanks to Brett Zamir
258 . Unit test refactoring for one logical test per test function
259 . Config and context parameters in ComplexHarness deprecated: instead, edit
260 the $config and $context member variables
261 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
262 really make a difference, but is good for completeness sake
263 . merge-library.php script refactored for greater code reusability and
266 2.1.1, released 2007-08-04
267 - Fix show-stopper bug in %URI.MakeAbsolute functionality
268 - Fix PHP4 syntax error in standalone version
269 . Add prefix directory to include path for standalone, this prevents
270 other installations from clobbering the standalone's URI schemes
271 . Single test methods can be invoked by prefixing with __only
273 2.1.0, released 2007-08-02
274 # flush-htmldefinition-cache.php superseded in favor of a generic
275 flush-definition-cache.php script, you can clear a specific cache
276 by passing its name as a parameter to the script
277 ! Phorum mod implemented for HTML Purifier
278 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
279 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
280 for PHP4 (DirectLex).
281 ! Standalone file now available, which greatly reduces the amount of
282 includes (although there are still a few files that reside in the
284 ! Relative URIs can now be transformed into their absolute equivalents
285 using %URI.Base and %URI.MakeAbsolute
286 ! Ruby implemented for XHTML 1.1

294 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
296 - Contents of <style> tags removed by default when tags are removed
297 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
298 for output cache invalidation
299 . ConfigForm printer now can retrieve CSS and JS files as strings, in
300 case HTML Purifier's directory is not publically accessible
301 . Introduce new text/itext configuration directive values: these represent
302 longer strings that would be more appropriately edited with a textarea
303 . Allow newlines to act as separators for lists, hashes, lookups and
305 . ConfigForm generates textareas instead of text inputs for lists, hashes,
306 lookups, text and itext fields
307 . Hidden element content removal genericized: %Core.HiddenElements can
308 be used to customize this behavior, by default <script> and <style> are
310 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
311 . Custom ChildDef added to default include list
312 . URIScheme reflection improved: will not attempt to include file if class
313 already exists. May clobber autoload, so I need to keep an eye on it
314 . ConfigSchema heavily optimized, will only collect information and validate
315 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
316 . AttrDef_URI unit tests and implementation refactored
317 . benchmarks/ directory now protected from public view with .htaccess file;
318 run the tests via command line
319 . URI scheme is munged off if there is no authority and the scheme is the
321 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
322 . Interface for URIScheme changed
323 . Generic URI object to hold components of URI added, most systems involved
324 in URI validation have been migrated to use it
325 . Custom filtering for URIs factored out to URIDefinition interface for
326 maximum extensibility
328 2.0.1, released 2007-06-27
329 ! Tag auto-closing now based on a ChildDef heuristic rather than a
330 manually set auto_close array; some behavior may change
331 ! Experimental AutoFormat functionality added: auto-paragraph and
332 linkify your HTML input by setting %AutoFormat.AutoParagraph and
333 %AutoFormat.Linkify to true
334 ! Newlines normalized internally, and then converted back to the
335 value of PHP_EOL. If this is not desired, set your newline format
336 using %Output.Newline.
337 ! Beta error collection, messages are implemented for the most generic
338 cases involving Lexing or Strategies
339 - Clean up special case code for <script> tags
340 - Reorder includes for DefinitionCache decorators, fixes a possible
342 - Fixed bug where manually modified definitions were not saved via cache
343 (mostly harmless, except for the fact that it would be a little slower)

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

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

475 %Attr.IDBlacklistRegexp
476 - Error messages are emitted when you attempt to "allow" elements or
477 attributes that HTML Purifier does not support
478 - Fix segfault in unit test. The problem is not very reproduceable and

481 1.5.0, released 2007-03-23
482 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
483 doesn't actually do anything yet, but keep your eyes peeled.
484 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
485 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

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