2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.3.1, unknown release date
13 # URI.Munge now munges URIs inside the same host that go from https
14 to http. Reported by Neike Taika-Tessaro.
15 # Core.EscapeNonASCIICharacters now always transforms entities to
16 entities, even if target encoding is UTF-8.
17 ! Added support for 'scope' attribute on tables.
18 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
19 <yramirez-htmlpurifier@adicio.com> for reporting.
20 - Explicitly initialize anonModule variable to null.
21 - Do not duplicate nofollow if already present. Thanks 178
23 - Do not add nofollow if hostname matches our current host. Thanks 178
24 for reporting, and Neike Taika-Tessaro for helping diagnose.
25 - Do not unset parser variable; this fixes intermittent serialization
27 - Fix iconv truncation bug, where non-UTF-8 target encodings see
28 output truncated after around 8000 characters.
30 4.3.0, released 2011-03-27
31 # Fixed broken caching of customized raw definitions, but requires an
32 API change. The old API still works but will emit a warning,
33 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
34 for how to upgrade your code.
35 # Protect against Internet Explorer innerHTML behavior by specially
36 treating attributes with backticks but no angled brackets, quotes or
37 spaces. This constitutes a slight semantic change, which can be
38 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
40 # Protect against cssText/innerHTML by restricting allowed characters
41 used in fonts further than mandated by the specification and encoding
42 some extra special characters in URLs. Reported by Neike
43 Taika-Tessaro and Mario Heiderich.
44 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
45 ! More types of SPL autoloaders allowed on later versions of PHP.
46 ! Implementations for position, top, left, right, bottom, z-index
47 when %CSS.Trusted is on.
48 ! Add %Cache.SerializerPermissions option for custom serializer
49 directory/file permissions
50 ! Fix longstanding bug in Flash support for non-IE browsers, and
51 allow more wmode attributes.
52 ! Add %CSS.AllowedFonts to restrict permissible font names.
53 - Switch to an iterative traversal of the DOM, which prevents us
54 from running out of stack space for deeply nested documents.
55 Thanks Maxim Krizhanovsky for contributing a patch.
56 - Make removal of conditional IE comments ungreedy; thanks Bernd
58 - Escape CDATA before removing Internet Explorer comments.
59 - Fix removal of id attributes under certain conditions by ensuring
60 armor attributes are preserved when recreating tags.
61 - Check if schema.ser was corrupted.
62 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
63 This safety check is only done for HTMLPurifier.auto.php; if you
64 are using standalone or the specialized includes files, you're
65 expected to know what you're doing.
66 - Stop repeatedly writing the cache file after I'm done customizing a
67 raw definition. Reported by ajh.
68 - Switch to using require_once in the Bootstrap to work around bad
69 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
70 - Fix URI handling when hostname is missing but scheme is present.
71 Reported by Neike Taika-Tessaro.
72 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
74 - Fix harmless notice from indexing into empty string. Thanks Matthijs
75 Kooijman <matthijs@stdin.nl> for reporting.
76 - Don't autoclose no parent elements are able to support the element
77 that triggered the autoclose. In particular fixes strange behavior
78 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
79 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
81 4.2.0, released 2010-09-15
82 ! Added %Core.RemoveProcessingInstructions, which lets you remove
84 ! Added %URI.DisableResources functionality; the directive originally
85 did nothing. Thanks David Rothstein for reporting.
86 ! Add documentation about configuration directive types.
87 ! Add %CSS.ForbiddenProperties configuration directive.
88 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
89 to utilize full-screen mode.
90 ! Add optional support for the <code>file</code> URI scheme, enable
91 by explicitly setting %URI.AllowedSchemes.
92 ! Add %Core.NormalizeNewlines options to allow turning off newline
94 - Fix improper handling of Internet Explorer conditional comments
95 by parser. Thanks zmonteca for reporting.
96 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
97 Thanks sidepodcast for the fix.
98 - Warn if an element is allowed, but an attribute it requires is
101 4.1.1, released 2010-05-31
102 - Fix undefined index warnings in maintenance scripts.
103 - Fix bug in DirectLex for parsing elements with a single attribute
105 - Rewrite CSS output logic for font-family and url(). Thanks Mario
106 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
107 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
108 - Emit an error for CollectErrors if a body is extracted
109 - Fix bug where in background-position for center keyword handling.
110 - Fix infinite loop when a wrapper element is inserted in a context
111 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
112 - Remove +x bit and shebang from index.php; only supported mode is to
113 explicitly call it with php.
114 - Make test script less chatty when log_errors is on.
116 4.1.0, released 2010-04-26
117 ! Support proprietary height attribute on table element
118 ! Support YouTube slideshows that contain /cp/ in their URL.
119 ! Support for data: URI scheme; not enabled by default, add it using
121 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
122 ! Support for Internet Explorer compatibility with %HTML.SafeObject
123 using %Output.FlashCompat.
124 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
125 - Always quote the insides of url(...) in CSS.
127 4.0.0, released 2009-07-07
128 # APIs for ConfigSchema subsystem have substantially changed. See
129 docs/dev-config-bcbreaks.txt for details; in essence, anything that
130 had both namespace and directive now have a single unified key.
131 # Some configuration directives were renamed, specifically:
132 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
133 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
134 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
135 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
136 As usual, the old directive names will still work, but will throw E_NOTICE
138 # The allowed values for class have been relaxed to allow all of CDATA for
139 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
140 %Attr.ClassUseCDATA to false.
141 # Instead of appending the content model to an old content model, a blank
142 element will replace the old content model. You can use #SUPER to get
143 the old content model.
144 ! More robust support for name="" and id=""
145 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
146 configuration, and have changes to that configuration be propagated
147 to all of its children.
148 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
149 the name attribute when set. Use with care. Thanks Ian Cook for
151 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
152 tags that contain non-breaking spaces as well other whitespace. You
153 can also modify which tags should have maintained with
154 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
155 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
156 classes users can use to a specified finite set of classes, and
157 %Attr.ForbiddenClasses, which is the logical inverse.
158 ! You can now maintain your own configuration schema directories by
159 creating a config-schema.php file or passing an extra argument. Check
160 docs/dev-config-schema.html for more details.
161 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
162 your configuration in a compact serial file, which you can unserialize
163 and use directly without having to go through the overhead of setup.
164 - Fix bug where URIDefinition would not get cleared if it's directives got
166 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
167 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
168 - Make %URI.Munge not apply to links that have the same host as your host.
169 - Prevent stray </body> tag from truncating output, if a second </body>
171 . Created script maintenance/rename-config.php for renaming a configuration
172 directive while maintaining its alias. This script does not change source code.
173 . Implement namespace locking for definition construction, to prevent
174 bugs where a directive is used for definition construction but is not
175 used to construct the cache hash.
177 3.3.0, released 2009-02-16
178 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
179 ! Implement generic property list classess
180 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
181 does not do the "right thing" with characters not supported in the output
183 - Spellcheck UTF-8: The Secret To Character Encoding
184 - Fix improper removal of the contents of elements with only whitespace. Thanks
185 Eric Wald for reporting.
186 - Fix broken test suite in versions of PHP without spl_autoload_register()
187 - Fix degenerate case with YouTube filter involving double hyphens.
188 Thanks Pierre Attar for reporting.
189 - Fix YouTube rendering problem on certain versions of Firefox.
190 - Fix CSSDefinition Printer problems with decorators
191 - Add text parameter to unit tests, forces text output
192 . Add verbose mode to command line test runner, use (--verbose)
193 . Turn on unit tests for UnitConverter
194 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
195 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
197 . Removed trailing whitespace from all text files, see
198 remote-trailing-whitespace.php maintenance script.
199 . Convert configuration to use property list backend.
201 3.2.0, released 2008-10-31
202 # Using %Core.CollectErrors forces line number/column tracking on, whereas
203 previously you could theoretically turn it off.
204 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
205 use handleEnd() instead.
206 ! %Output.AttrSort for when you need your attributes in alphabetical order to
207 deal with a bug in FCKEditor. Requested by frank farmer.
208 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
209 ! Proper support for name attribute. It is now allowed and equivalent to the id
210 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
211 is heavy (for all doctypes).
212 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
213 use on hand-written HTML.
214 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
215 the strategy to be used, standalone, on untrusted input.
216 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
217 processing of left angled brackets in smileys and other whatnot.
218 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
219 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
220 the --only-phpt parameter, although for backwards-compatibility the flag
222 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
223 Users who are not performing inbound filtering, this may seem a little
224 useless, but as a bonus, the test suite and handling of edge cases is also
226 ! Experimental implementation of forms for %HTML.Trusted
227 ! Track column numbers when maintain line numbers is on
228 ! Proprietary 'background' attribute on table-related elements converted into
229 corresponding CSS. Thanks Fusemail for sponsoring this feature!
230 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
232 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
233 time of operation varies slightly from notifyEnd() as *all* end tokens are
234 processed by the injector before they are subject to the well-formedness rules.
235 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
236 basename of image when not present.
237 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
238 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
239 the other involving an undefined $is_folder error.
240 - Throw error when %Core.Encoding is set to a spurious value. Previously,
241 this errored silently and returned false.
242 - Redirected stderr to stdout for flush error output.
243 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
245 - Do not re-munge URL if the output URL has the same host as the input URL.
247 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
248 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
249 - Fix bug with inline elements in blockquotes conflicting with strict doctype
250 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
251 - Fix bug where dots and double-dots in absolute URLs without hostname were
252 not collapsed by URIFilter_MakeAbsolute.
253 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
254 by reordering their addition.
255 - Will now throw exception on many error conditions during lexer creation; also
256 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
258 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
259 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
260 Reported by David Morton.
261 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
262 for more interesting filter-backtracking
263 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
264 index to reprocess tokens.
265 . StringHashParser now allows for multiline sections with "empty" content;
266 previously the section would remain undefined.
267 . Added --quick option to multitest.php, which tests only the most recent
268 release for each series.
269 . Added --distro option to multitest.php, which accepts either 'normal' or
270 'standalone'. This supercedes --exclude-normal and --exclude-standalone
272 3.1.1, released 2008-06-19
273 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
274 In order to enable this again, please set %URI.MungeResources to true.
275 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
276 and height/width HTML with %HTML.MaxImgLength.
277 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
278 for sponsoring this feature. Check out the corresponding documentation
279 for details. (Att Nightly testers: The API for this feature changed before
280 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
281 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
282 ! Implemented post URI filtering. Set member variable $post to true to set
284 ! Allow modules to define injectors via $info_injector. Injectors are
285 automatically disabled if injector's needed elements are not found.
286 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
287 Thanks Chris for sponsoring. If you've been using ad hoc code from the
288 forums, PLEASE use this instead.
289 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
290 embedded, tag name, attribute name, CSS property name). See %URI.Munge
291 for more details. Requested by Jochem Blok.
292 - Disable percent height/width attributes for img.
293 - AttrValidator operations are now atomic; updates to attributes are not
294 manifest in token until end of operations. This prevents naughty internal
295 code from directly modifying CurrentToken when they're not supposed to.
296 This semantics change was requested by frank farmer.
297 - Percent encoding checks enabled for URI query and fragment
298 - Fix stray backslashes in font-family; CSS Unicode character escapes are
299 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
301 - Improve parseCDATA algorithm to take into account newline normalization
302 - Account for browser confusion between Yen character and backslash in
303 Shift_JIS encoding. This fix generalizes to any other encoding which is not
304 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
305 - Fix missing configuration parameter in Generator calls. Thanks vs for the
307 - Improved adherence to Unicode by checking for non-character codepoints.
308 Thanks Geoffrey Sneddon for reporting. This may result in degraded
309 performance for extremely large inputs.
310 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
312 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
313 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
315 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
316 to __construct($min, $max). __construct(true) is equivalent to
318 . Added HTMLPurifier_AttrDef_Switch class
319 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
320 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
321 get this called with the configuration object. All modules now
322 use this rather than __construct(), although legacy code using constructors
323 will still work--the new format, however, lets modules access the
324 configuration object for HTML namespace dependant tweaks.
325 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
326 . ConfigSchema data-structure heavily optimized; on average it uses a third
327 the memory it did previously. The interface has changed accordingly,
328 consult changes to HTMLPurifier_Config for details.
329 . Variable parsing types now are magic integers instead of strings
330 . Added benchmark for ConfigSchema
331 . HTMLPurifier_Generator requires $config and $context parameters. If you
332 don't know what they should be, use HTMLPurifier_Config::createDefault()
333 and new HTMLPurifier_Context().
334 . Printers now properly distinguish between output configuration, and
335 target configuration. This is not applicable to scripts using
336 the Printers for HTML Purifier related tasks.
337 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
338 fatal errors will ensue.
339 . URIFilter->prepare can return false in order to abort loading of the filter
340 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
341 an external resource.
342 . %URI.Munge functionality factored out into a post-filter class.
343 . Added CurrentCSSProperty context variable during CSS validation
345 3.1.0, released 2008-05-18
346 # Unnecessary references to objects (vestiges of PHP4) removed from method
347 signatures. The following methods do not need references when assigning from
348 them and will result in E_STRICT errors if you try:
349 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
350 + HTMLPurifier_ConfigSchema::instance()
351 + HTMLPurifier_DefinitionCacheFactory::instance()
352 + HTMLPurifier_DefinitionCacheFactory->create()
353 + HTMLPurifier_DoctypeRegistry->register()
354 + HTMLPurifier_DoctypeRegistry->get()
355 + HTMLPurifier_HTMLModule->addElement()
356 + HTMLPurifier_HTMLModule->addBlankElement()
357 + HTMLPurifier_LanguageFactory::instance()
358 # Printer_ConfigForm's get*() functions were static-ified
359 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
360 form of tag@attr, NOT tag.attr (which will throw an error and won't do
361 anything). This is for forwards compatibility with XML; you'd do best
362 to migrate an %HTML.AllowedAttributes directives to this syntax too.
363 ! Allow index to be false for config from form creation
364 ! Added HTMLPurifier::VERSION constant
365 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
366 and allows for version numbers like "3.1.0-dev".
367 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
368 ! HTML Purifier's URI handling is a lot more robust, with much stricter
369 validation checks and better percent encoding handling. Thanks Gareth Heyes
370 for indicating security vulnerabilities from lax percent encoding.
371 ! Bootstrap autoloader deals more robustly with classes that don't exist,
372 preventing class_exists($class, true) from barfing.
373 - InterchangeBuilder now alphabetizes its lists
374 - Validation error in configdoc output fixed
375 - Iconv and other encoding errors muted even with custom error handlers that
376 do not honor error_reporting
377 - Add protection against imagecrash attack with CSS height/width
378 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
379 - Fixed and revamped broken ConfigForm smoketest
380 - Bug with bool/null fields in Printer_ConfigForm fixed
381 - Bug with global forbidden attributes fixed
382 - Improved error messages for allowed and forbidden HTML elements and attributes
383 - Missing (or null) in configdoc documentation restored
384 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
385 of DOM), HTML Purifier punts to DirectLex
386 - Fatal error with unserialization of ScriptRequired
387 - Created directories are now chmod'ed properly
388 - Fixed bug with fallback languages in LanguageFactory
389 - Standalone testing setup properly with autoload
390 . Out-of-date documentation revised
391 . UTF-8 encoding check optimization as suggested by Diego
392 . HTMLPurifier_Error removed in favor of exceptions
393 . More copy() function removed; should use clone instead
394 . More extensive unit tests for HTMLDefinition
395 . assertPurification moved to central harness
396 . HTMLPurifier_Generator accepts $config and $context parameters during
397 instantiation, not runtime
398 . Double-quotes outside of attribute values are now unescaped
400 3.1.0rc1, released 2008-04-22
401 # Autoload support added. Internal require_once's removed in favor of an
402 explicit require list or autoloading. To use HTML Purifier,
403 you must now either use HTMLPurifier.auto.php
404 or HTMLPurifier.includes.php; setting the include path and including
405 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
406 as well to register our autoload handler (or modify your autoload function
407 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
408 HTMLPurifier.safe-includes.php for a less performance friendly but more
409 user-friendly library load.
410 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
411 information is stored in the ConfigSchema directory, and the
412 maintenance/generate-schema-cache.php generates the schema.ser file, which
413 is now instantiated. Support for userland schema changes coming soon!
414 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
415 alias; to get rid of these errors just modify your configuration to use
416 the new directive name.
417 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
418 enabled using %Filter.$filter_name or by setting your own filters using
420 # Directive-level safety properties superceded in favor of module-level
421 safety. Internal method HTMLModule->addElement() has changed, although
422 the externally visible HTMLDefinition->addElement has *not* changed.
423 ! Extra utility classes for testing and non-library operations can
424 be found in extras/. Specifically, these are FSTools and ConfigDoc.
425 You may find a use for these in your own project, but right now they
426 are highly experimental and volatile.
427 ! Integration with PHPT allows for automated smoketests
428 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
429 by Chris. You can enable them with %HTML.Proprietary if your client
431 ! Support for !important CSS cascade modifier. By default, this will be stripped
432 from CSS, but you can enable it using %CSS.AllowImportant
433 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
435 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
436 Developer error (not enduser error) can cause these to be triggered.
437 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
438 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
439 mucking around with HTMLPurifier_CSSDefinition
440 ! ConfigDoc output has been enhanced with version and deprecation info.
441 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
442 - Autoclose now operates iteratively, i.e. <span><span><div> now has
443 both span tags closed.
444 - Various HTMLPurifier_Config convenience functions now accept another parameter
445 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
447 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
448 - Fix bug in ExtractStyleBlocks with comments in style tags
449 - Fix bug in comment parsing for DirectLex
450 - Flush output now displayed when in command line mode for unit tester
451 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
452 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
453 on the same element without emitting errors.
454 - Fixed fatal error in PH5P lexer with invalid tag names
455 . Plugins now get their own changelogs according to project conventions.
456 . Convert tokens to use instanceof, reducing memory footprint and
457 improving comparison speed.
458 . Dry runs now supported in SimpleTest; testing facilities improved
459 . Bootstrap class added for handling autoloading functionality
460 . Implemented recursive glob at FSTools->globr
461 . ConfigSchema now has instance methods for all corresponding define*
463 . A couple of new historical maintenance scripts were added.
464 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
465 . tests/index.php can now be run from any directory.
466 . HTMLPurifier_Token subclasses split into seperate files
467 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
468 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
469 . New --php=php flag added, allows PHP executable to be specified (command
471 . htmlpurifier_add_test() preferred method to translate test files in to
472 classes, because it handles PHPT files too.
473 . Debugger class is deprecated and will be removed soon.
474 . Command line argument parsing for testing scripts revamped, now --opt value
476 . Smoketests now cleanup after magic quotes
477 . Generator now can output comments (however, comments are still stripped

504 %Filter.ExtractStyleBlocksScope
505 ! Experimental support for some proprietary CSS attributes allowed:
506 opacity (and all of the browser-specific equivalents) and scrollbar colors.
507 Enable by setting %CSS.Proprietary to true.

549 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
550 to better communicate its purpose

576 - Fix non-visible parsing error in DirectLex with empty tags that have
577 slashes inside attribute values.
578 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly

661 linkify your HTML input by setting %AutoFormat.AutoParagraph and
662 %AutoFormat.Linkify to true

711 new objects via make()
712 # Definitions (esp. HTMLDefinition) are now cached for a significant
