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 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
19 ! Properly handle sub-lists directly nested inside of lists in
20 a standards compliant way, by moving them into the preceding <li>
21 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
22 limited allowed comments in untrusted situations.
23 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
24 <yramirez-htmlpurifier@adicio.com> for reporting.
25 - Explicitly initialize anonModule variable to null.
26 - Do not duplicate nofollow if already present. Thanks 178
28 - Do not add nofollow if hostname matches our current host. Thanks 178
29 for reporting, and Neike Taika-Tessaro for helping diagnose.
30 - Do not unset parser variable; this fixes intermittent serialization
31 problems. Thanks Neike Taika-Tessaro for reporting, bill
32 <10010tiger@gmail.com> for diagnosing.
33 - Fix iconv truncation bug, where non-UTF-8 target encodings see
34 output truncated after around 8000 characters. Thanks Jörg Ludwig
35 <joerg.ludwig@iserv.eu> for reporting.
36 - Fix broken table content model for XHTML1.1 (and also earlier
37 versions, although the W3C validator doesn't catch those violations).
38 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
40 4.3.0, released 2011-03-27
41 # Fixed broken caching of customized raw definitions, but requires an
42 API change. The old API still works but will emit a warning,
43 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
44 for how to upgrade your code.
45 # Protect against Internet Explorer innerHTML behavior by specially
46 treating attributes with backticks but no angled brackets, quotes or
47 spaces. This constitutes a slight semantic change, which can be
48 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
50 # Protect against cssText/innerHTML by restricting allowed characters
51 used in fonts further than mandated by the specification and encoding
52 some extra special characters in URLs. Reported by Neike
53 Taika-Tessaro and Mario Heiderich.
54 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
55 ! More types of SPL autoloaders allowed on later versions of PHP.
56 ! Implementations for position, top, left, right, bottom, z-index
57 when %CSS.Trusted is on.
58 ! Add %Cache.SerializerPermissions option for custom serializer
59 directory/file permissions
60 ! Fix longstanding bug in Flash support for non-IE browsers, and
61 allow more wmode attributes.
62 ! Add %CSS.AllowedFonts to restrict permissible font names.
63 - Switch to an iterative traversal of the DOM, which prevents us
64 from running out of stack space for deeply nested documents.
65 Thanks Maxim Krizhanovsky for contributing a patch.
66 - Make removal of conditional IE comments ungreedy; thanks Bernd
68 - Escape CDATA before removing Internet Explorer comments.
69 - Fix removal of id attributes under certain conditions by ensuring
70 armor attributes are preserved when recreating tags.
71 - Check if schema.ser was corrupted.
72 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
73 This safety check is only done for HTMLPurifier.auto.php; if you
74 are using standalone or the specialized includes files, you're
75 expected to know what you're doing.
76 - Stop repeatedly writing the cache file after I'm done customizing a
77 raw definition. Reported by ajh.
78 - Switch to using require_once in the Bootstrap to work around bad
79 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
80 - Fix URI handling when hostname is missing but scheme is present.
81 Reported by Neike Taika-Tessaro.
82 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
84 - Fix harmless notice from indexing into empty string. Thanks Matthijs
85 Kooijman <matthijs@stdin.nl> for reporting.
86 - Don't autoclose no parent elements are able to support the element
87 that triggered the autoclose. In particular fixes strange behavior
88 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
89 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
91 4.2.0, released 2010-09-15
92 ! Added %Core.RemoveProcessingInstructions, which lets you remove
94 ! Added %URI.DisableResources functionality; the directive originally
95 did nothing. Thanks David Rothstein for reporting.
96 ! Add documentation about configuration directive types.
97 ! Add %CSS.ForbiddenProperties configuration directive.
98 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
99 to utilize full-screen mode.
100 ! Add optional support for the <code>file</code> URI scheme, enable
101 by explicitly setting %URI.AllowedSchemes.
102 ! Add %Core.NormalizeNewlines options to allow turning off newline
104 - Fix improper handling of Internet Explorer conditional comments
105 by parser. Thanks zmonteca for reporting.
106 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
107 Thanks sidepodcast for the fix.
108 - Warn if an element is allowed, but an attribute it requires is
111 4.1.1, released 2010-05-31
112 - Fix undefined index warnings in maintenance scripts.
113 - Fix bug in DirectLex for parsing elements with a single attribute
115 - Rewrite CSS output logic for font-family and url(). Thanks Mario
116 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
117 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
118 - Emit an error for CollectErrors if a body is extracted
119 - Fix bug where in background-position for center keyword handling.
120 - Fix infinite loop when a wrapper element is inserted in a context
121 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
122 - Remove +x bit and shebang from index.php; only supported mode is to
123 explicitly call it with php.
124 - Make test script less chatty when log_errors is on.
126 4.1.0, released 2010-04-26
127 ! Support proprietary height attribute on table element
128 ! Support YouTube slideshows that contain /cp/ in their URL.
129 ! Support for data: URI scheme; not enabled by default, add it using
131 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
132 ! Support for Internet Explorer compatibility with %HTML.SafeObject
133 using %Output.FlashCompat.
134 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
135 - Always quote the insides of url(...) in CSS.
137 4.0.0, released 2009-07-07
138 # APIs for ConfigSchema subsystem have substantially changed. See
139 docs/dev-config-bcbreaks.txt for details; in essence, anything that
140 had both namespace and directive now have a single unified key.
141 # Some configuration directives were renamed, specifically:
142 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
143 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
144 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
145 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
146 As usual, the old directive names will still work, but will throw E_NOTICE
148 # The allowed values for class have been relaxed to allow all of CDATA for
149 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
150 %Attr.ClassUseCDATA to false.
151 # Instead of appending the content model to an old content model, a blank
152 element will replace the old content model. You can use #SUPER to get
153 the old content model.
154 ! More robust support for name="" and id=""
155 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
156 configuration, and have changes to that configuration be propagated
157 to all of its children.
158 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
159 the name attribute when set. Use with care. Thanks Ian Cook for
161 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
162 tags that contain non-breaking spaces as well other whitespace. You
163 can also modify which tags should have maintained with
164 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
165 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
166 classes users can use to a specified finite set of classes, and
167 %Attr.ForbiddenClasses, which is the logical inverse.
168 ! You can now maintain your own configuration schema directories by
169 creating a config-schema.php file or passing an extra argument. Check
170 docs/dev-config-schema.html for more details.
171 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
172 your configuration in a compact serial file, which you can unserialize
173 and use directly without having to go through the overhead of setup.
174 - Fix bug where URIDefinition would not get cleared if it's directives got
176 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
177 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
178 - Make %URI.Munge not apply to links that have the same host as your host.
179 - Prevent stray </body> tag from truncating output, if a second </body>
181 . Created script maintenance/rename-config.php for renaming a configuration
182 directive while maintaining its alias. This script does not change source code.
183 . Implement namespace locking for definition construction, to prevent
184 bugs where a directive is used for definition construction but is not
185 used to construct the cache hash.
187 3.3.0, released 2009-02-16
188 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
189 ! Implement generic property list classess
190 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
191 does not do the "right thing" with characters not supported in the output
193 - Spellcheck UTF-8: The Secret To Character Encoding
194 - Fix improper removal of the contents of elements with only whitespace. Thanks
195 Eric Wald for reporting.
196 - Fix broken test suite in versions of PHP without spl_autoload_register()
197 - Fix degenerate case with YouTube filter involving double hyphens.
198 Thanks Pierre Attar for reporting.
199 - Fix YouTube rendering problem on certain versions of Firefox.
200 - Fix CSSDefinition Printer problems with decorators
201 - Add text parameter to unit tests, forces text output
202 . Add verbose mode to command line test runner, use (--verbose)
203 . Turn on unit tests for UnitConverter
204 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
205 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
207 . Removed trailing whitespace from all text files, see
208 remote-trailing-whitespace.php maintenance script.
209 . Convert configuration to use property list backend.
211 3.2.0, released 2008-10-31
212 # Using %Core.CollectErrors forces line number/column tracking on, whereas
213 previously you could theoretically turn it off.
214 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
215 use handleEnd() instead.
216 ! %Output.AttrSort for when you need your attributes in alphabetical order to
217 deal with a bug in FCKEditor. Requested by frank farmer.
218 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
219 ! Proper support for name attribute. It is now allowed and equivalent to the id
220 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
221 is heavy (for all doctypes).
222 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
223 use on hand-written HTML.
224 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
225 the strategy to be used, standalone, on untrusted input.
226 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
227 processing of left angled brackets in smileys and other whatnot.
228 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
229 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
230 the --only-phpt parameter, although for backwards-compatibility the flag
232 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
233 Users who are not performing inbound filtering, this may seem a little
234 useless, but as a bonus, the test suite and handling of edge cases is also
236 ! Experimental implementation of forms for %HTML.Trusted
237 ! Track column numbers when maintain line numbers is on
238 ! Proprietary 'background' attribute on table-related elements converted into
239 corresponding CSS. Thanks Fusemail for sponsoring this feature!
240 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
242 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
243 time of operation varies slightly from notifyEnd() as *all* end tokens are
244 processed by the injector before they are subject to the well-formedness rules.
245 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
246 basename of image when not present.
247 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
248 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
249 the other involving an undefined $is_folder error.
250 - Throw error when %Core.Encoding is set to a spurious value. Previously,
251 this errored silently and returned false.
252 - Redirected stderr to stdout for flush error output.
253 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
255 - Do not re-munge URL if the output URL has the same host as the input URL.
257 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
258 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
259 - Fix bug with inline elements in blockquotes conflicting with strict doctype
260 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
261 - Fix bug where dots and double-dots in absolute URLs without hostname were
262 not collapsed by URIFilter_MakeAbsolute.
263 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
264 by reordering their addition.
265 - Will now throw exception on many error conditions during lexer creation; also
266 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
268 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
269 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
270 Reported by David Morton.
271 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
272 for more interesting filter-backtracking
273 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
274 index to reprocess tokens.
275 . StringHashParser now allows for multiline sections with "empty" content;
276 previously the section would remain undefined.
277 . Added --quick option to multitest.php, which tests only the most recent
278 release for each series.
279 . Added --distro option to multitest.php, which accepts either 'normal' or
280 'standalone'. This supercedes --exclude-normal and --exclude-standalone
282 3.1.1, released 2008-06-19
283 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
284 In order to enable this again, please set %URI.MungeResources to true.
285 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
286 and height/width HTML with %HTML.MaxImgLength.
287 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
288 for sponsoring this feature. Check out the corresponding documentation
289 for details. (Att Nightly testers: The API for this feature changed before
290 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
291 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
292 ! Implemented post URI filtering. Set member variable $post to true to set
294 ! Allow modules to define injectors via $info_injector. Injectors are
295 automatically disabled if injector's needed elements are not found.
296 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
297 Thanks Chris for sponsoring. If you've been using ad hoc code from the
298 forums, PLEASE use this instead.
299 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
300 embedded, tag name, attribute name, CSS property name). See %URI.Munge
301 for more details. Requested by Jochem Blok.
302 - Disable percent height/width attributes for img.
303 - AttrValidator operations are now atomic; updates to attributes are not
304 manifest in token until end of operations. This prevents naughty internal
305 code from directly modifying CurrentToken when they're not supposed to.
306 This semantics change was requested by frank farmer.
307 - Percent encoding checks enabled for URI query and fragment
308 - Fix stray backslashes in font-family; CSS Unicode character escapes are
309 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
311 - Improve parseCDATA algorithm to take into account newline normalization
312 - Account for browser confusion between Yen character and backslash in
313 Shift_JIS encoding. This fix generalizes to any other encoding which is not
314 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
315 - Fix missing configuration parameter in Generator calls. Thanks vs for the
317 - Improved adherence to Unicode by checking for non-character codepoints.
318 Thanks Geoffrey Sneddon for reporting. This may result in degraded
319 performance for extremely large inputs.
320 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
322 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
323 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
325 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
326 to __construct($min, $max). __construct(true) is equivalent to
328 . Added HTMLPurifier_AttrDef_Switch class
329 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
330 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
331 get this called with the configuration object. All modules now
332 use this rather than __construct(), although legacy code using constructors
333 will still work--the new format, however, lets modules access the
334 configuration object for HTML namespace dependant tweaks.
335 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
336 . ConfigSchema data-structure heavily optimized; on average it uses a third
337 the memory it did previously. The interface has changed accordingly,
338 consult changes to HTMLPurifier_Config for details.
339 . Variable parsing types now are magic integers instead of strings
340 . Added benchmark for ConfigSchema
341 . HTMLPurifier_Generator requires $config and $context parameters. If you
342 don't know what they should be, use HTMLPurifier_Config::createDefault()
343 and new HTMLPurifier_Context().
344 . Printers now properly distinguish between output configuration, and
345 target configuration. This is not applicable to scripts using
346 the Printers for HTML Purifier related tasks.
347 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
348 fatal errors will ensue.
349 . URIFilter->prepare can return false in order to abort loading of the filter
350 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
351 an external resource.
352 . %URI.Munge functionality factored out into a post-filter class.
353 . Added CurrentCSSProperty context variable during CSS validation
355 3.1.0, released 2008-05-18
356 # Unnecessary references to objects (vestiges of PHP4) removed from method
357 signatures. The following methods do not need references when assigning from
358 them and will result in E_STRICT errors if you try:
359 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
360 + HTMLPurifier_ConfigSchema::instance()
361 + HTMLPurifier_DefinitionCacheFactory::instance()
362 + HTMLPurifier_DefinitionCacheFactory->create()
363 + HTMLPurifier_DoctypeRegistry->register()
364 + HTMLPurifier_DoctypeRegistry->get()
365 + HTMLPurifier_HTMLModule->addElement()
366 + HTMLPurifier_HTMLModule->addBlankElement()
367 + HTMLPurifier_LanguageFactory::instance()
368 # Printer_ConfigForm's get*() functions were static-ified
369 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
370 form of tag@attr, NOT tag.attr (which will throw an error and won't do
371 anything). This is for forwards compatibility with XML; you'd do best
372 to migrate an %HTML.AllowedAttributes directives to this syntax too.
373 ! Allow index to be false for config from form creation
374 ! Added HTMLPurifier::VERSION constant
375 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
376 and allows for version numbers like "3.1.0-dev".
377 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
378 ! HTML Purifier's URI handling is a lot more robust, with much stricter
379 validation checks and better percent encoding handling. Thanks Gareth Heyes
380 for indicating security vulnerabilities from lax percent encoding.
381 ! Bootstrap autoloader deals more robustly with classes that don't exist,
382 preventing class_exists($class, true) from barfing.
383 - InterchangeBuilder now alphabetizes its lists
384 - Validation error in configdoc output fixed
385 - Iconv and other encoding errors muted even with custom error handlers that
386 do not honor error_reporting
387 - Add protection against imagecrash attack with CSS height/width
388 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
389 - Fixed and revamped broken ConfigForm smoketest
390 - Bug with bool/null fields in Printer_ConfigForm fixed
391 - Bug with global forbidden attributes fixed
392 - Improved error messages for allowed and forbidden HTML elements and attributes
393 - Missing (or null) in configdoc documentation restored
394 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
395 of DOM), HTML Purifier punts to DirectLex
396 - Fatal error with unserialization of ScriptRequired
397 - Created directories are now chmod'ed properly
398 - Fixed bug with fallback languages in LanguageFactory
399 - Standalone testing setup properly with autoload
400 . Out-of-date documentation revised
401 . UTF-8 encoding check optimization as suggested by Diego
402 . HTMLPurifier_Error removed in favor of exceptions
403 . More copy() function removed; should use clone instead
404 . More extensive unit tests for HTMLDefinition
405 . assertPurification moved to central harness
406 . HTMLPurifier_Generator accepts $config and $context parameters during
407 instantiation, not runtime
408 . Double-quotes outside of attribute values are now unescaped
410 3.1.0rc1, released 2008-04-22
411 # Autoload support added. Internal require_once's removed in favor of an
412 explicit require list or autoloading. To use HTML Purifier,
413 you must now either use HTMLPurifier.auto.php
414 or HTMLPurifier.includes.php; setting the include path and including
415 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
416 as well to register our autoload handler (or modify your autoload function
417 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
418 HTMLPurifier.safe-includes.php for a less performance friendly but more
419 user-friendly library load.
420 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
421 information is stored in the ConfigSchema directory, and the
422 maintenance/generate-schema-cache.php generates the schema.ser file, which
423 is now instantiated. Support for userland schema changes coming soon!
424 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
425 alias; to get rid of these errors just modify your configuration to use
426 the new directive name.
427 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
428 enabled using %Filter.$filter_name or by setting your own filters using
430 # Directive-level safety properties superceded in favor of module-level
431 safety. Internal method HTMLModule->addElement() has changed, although
432 the externally visible HTMLDefinition->addElement has *not* changed.
433 ! Extra utility classes for testing and non-library operations can
434 be found in extras/. Specifically, these are FSTools and ConfigDoc.
435 You may find a use for these in your own project, but right now they
436 are highly experimental and volatile.
437 ! Integration with PHPT allows for automated smoketests
438 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
439 by Chris. You can enable them with %HTML.Proprietary if your client
441 ! Support for !important CSS cascade modifier. By default, this will be stripped
442 from CSS, but you can enable it using %CSS.AllowImportant
443 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
445 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
446 Developer error (not enduser error) can cause these to be triggered.
447 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
448 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
449 mucking around with HTMLPurifier_CSSDefinition
450 ! ConfigDoc output has been enhanced with version and deprecation info.
451 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
452 - Autoclose now operates iteratively, i.e. <span><span><div> now has
453 both span tags closed.
454 - Various HTMLPurifier_Config convenience functions now accept another parameter
455 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
457 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
458 - Fix bug in ExtractStyleBlocks with comments in style tags
459 - Fix bug in comment parsing for DirectLex
460 - Flush output now displayed when in command line mode for unit tester
461 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
462 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
463 on the same element without emitting errors.
464 - Fixed fatal error in PH5P lexer with invalid tag names
465 . Plugins now get their own changelogs according to project conventions.
466 . Convert tokens to use instanceof, reducing memory footprint and
467 improving comparison speed.
468 . Dry runs now supported in SimpleTest; testing facilities improved
469 . Bootstrap class added for handling autoloading functionality
470 . Implemented recursive glob at FSTools->globr
471 . ConfigSchema now has instance methods for all corresponding define*
473 . A couple of new historical maintenance scripts were added.

514 %Filter.ExtractStyleBlocksScope
515 ! Experimental support for some proprietary CSS attributes allowed:
516 opacity (and all of the browser-specific equivalents) and scrollbar colors.
517 Enable by setting %CSS.Proprietary to true.

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

671 linkify your HTML input by setting %AutoFormat.AutoParagraph and
672 %AutoFormat.Linkify to true
