1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
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 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
22 <yramirez-htmlpurifier@adicio.com> for reporting.
23 - Explicitly initialize anonModule variable to null.
24 - Do not duplicate nofollow if already present. Thanks 178
26 - Do not add nofollow if hostname matches our current host. Thanks 178
27 for reporting, and Neike Taika-Tessaro for helping diagnose.
28 - Do not unset parser variable; this fixes intermittent serialization
30 - Fix iconv truncation bug, where non-UTF-8 target encodings see
31 output truncated after around 8000 characters.
32 - Fix broken table content model for XHTML1.1 (and also earlier
33 versions, although the W3C validator doesn't catch those violations)
35 4.3.0, released 2011-03-27
36 # Fixed broken caching of customized raw definitions, but requires an
37 API change. The old API still works but will emit a warning,
38 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
39 for how to upgrade your code.
40 # Protect against Internet Explorer innerHTML behavior by specially
41 treating attributes with backticks but no angled brackets, quotes or
42 spaces. This constitutes a slight semantic change, which can be
43 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
45 # Protect against cssText/innerHTML by restricting allowed characters
46 used in fonts further than mandated by the specification and encoding
47 some extra special characters in URLs. Reported by Neike
48 Taika-Tessaro and Mario Heiderich.
49 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
50 ! More types of SPL autoloaders allowed on later versions of PHP.
51 ! Implementations for position, top, left, right, bottom, z-index
52 when %CSS.Trusted is on.
53 ! Add %Cache.SerializerPermissions option for custom serializer
54 directory/file permissions
55 ! Fix longstanding bug in Flash support for non-IE browsers, and
56 allow more wmode attributes.
57 ! Add %CSS.AllowedFonts to restrict permissible font names.
58 - Switch to an iterative traversal of the DOM, which prevents us
59 from running out of stack space for deeply nested documents.
60 Thanks Maxim Krizhanovsky for contributing a patch.
61 - Make removal of conditional IE comments ungreedy; thanks Bernd
63 - Escape CDATA before removing Internet Explorer comments.
64 - Fix removal of id attributes under certain conditions by ensuring
65 armor attributes are preserved when recreating tags.
66 - Check if schema.ser was corrupted.
67 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
68 This safety check is only done for HTMLPurifier.auto.php; if you
69 are using standalone or the specialized includes files, you're
70 expected to know what you're doing.
71 - Stop repeatedly writing the cache file after I'm done customizing a
72 raw definition. Reported by ajh.
73 - Switch to using require_once in the Bootstrap to work around bad
74 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
75 - Fix URI handling when hostname is missing but scheme is present.
76 Reported by Neike Taika-Tessaro.
77 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
79 - Fix harmless notice from indexing into empty string. Thanks Matthijs
80 Kooijman <matthijs@stdin.nl> for reporting.
81 - Don't autoclose no parent elements are able to support the element
82 that triggered the autoclose. In particular fixes strange behavior
83 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
84 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
86 4.2.0, released 2010-09-15
87 ! Added %Core.RemoveProcessingInstructions, which lets you remove
89 ! Added %URI.DisableResources functionality; the directive originally
90 did nothing. Thanks David Rothstein for reporting.
91 ! Add documentation about configuration directive types.
92 ! Add %CSS.ForbiddenProperties configuration directive.
93 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
94 to utilize full-screen mode.
95 ! Add optional support for the <code>file</code> URI scheme, enable
96 by explicitly setting %URI.AllowedSchemes.
97 ! Add %Core.NormalizeNewlines options to allow turning off newline
99 - Fix improper handling of Internet Explorer conditional comments
100 by parser. Thanks zmonteca for reporting.
101 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
102 Thanks sidepodcast for the fix.
103 - Warn if an element is allowed, but an attribute it requires is
106 4.1.1, released 2010-05-31
107 - Fix undefined index warnings in maintenance scripts.
108 - Fix bug in DirectLex for parsing elements with a single attribute
110 - Rewrite CSS output logic for font-family and url(). Thanks Mario
111 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
112 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
113 - Emit an error for CollectErrors if a body is extracted
114 - Fix bug where in background-position for center keyword handling.
115 - Fix infinite loop when a wrapper element is inserted in a context
116 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
117 - Remove +x bit and shebang from index.php; only supported mode is to
118 explicitly call it with php.
119 - Make test script less chatty when log_errors is on.
121 4.1.0, released 2010-04-26
122 ! Support proprietary height attribute on table element
123 ! Support YouTube slideshows that contain /cp/ in their URL.
124 ! Support for data: URI scheme; not enabled by default, add it using
126 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
127 ! Support for Internet Explorer compatibility with %HTML.SafeObject
128 using %Output.FlashCompat.
129 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
130 - Always quote the insides of url(...) in CSS.
132 4.0.0, released 2009-07-07
133 # APIs for ConfigSchema subsystem have substantially changed. See
134 docs/dev-config-bcbreaks.txt for details; in essence, anything that
135 had both namespace and directive now have a single unified key.
136 # Some configuration directives were renamed, specifically:
137 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
138 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
139 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
140 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
141 As usual, the old directive names will still work, but will throw E_NOTICE
143 # The allowed values for class have been relaxed to allow all of CDATA for
144 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
145 %Attr.ClassUseCDATA to false.
146 # Instead of appending the content model to an old content model, a blank
147 element will replace the old content model. You can use #SUPER to get
148 the old content model.
149 ! More robust support for name="" and id=""
150 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
151 configuration, and have changes to that configuration be propagated
152 to all of its children.
153 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
154 the name attribute when set. Use with care. Thanks Ian Cook for
156 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
157 tags that contain non-breaking spaces as well other whitespace. You
158 can also modify which tags should have maintained with
159 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
160 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
161 classes users can use to a specified finite set of classes, and
162 %Attr.ForbiddenClasses, which is the logical inverse.
163 ! You can now maintain your own configuration schema directories by
164 creating a config-schema.php file or passing an extra argument. Check
165 docs/dev-config-schema.html for more details.
166 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
167 your configuration in a compact serial file, which you can unserialize
168 and use directly without having to go through the overhead of setup.
169 - Fix bug where URIDefinition would not get cleared if it's directives got
171 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
172 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
173 - Make %URI.Munge not apply to links that have the same host as your host.
174 - Prevent stray </body> tag from truncating output, if a second </body>
176 . Created script maintenance/rename-config.php for renaming a configuration
177 directive while maintaining its alias. This script does not change source code.
178 . Implement namespace locking for definition construction, to prevent
179 bugs where a directive is used for definition construction but is not
180 used to construct the cache hash.
182 3.3.0, released 2009-02-16
183 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
184 ! Implement generic property list classess
185 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
186 does not do the "right thing" with characters not supported in the output
188 - Spellcheck UTF-8: The Secret To Character Encoding
189 - Fix improper removal of the contents of elements with only whitespace. Thanks
190 Eric Wald for reporting.
191 - Fix broken test suite in versions of PHP without spl_autoload_register()
192 - Fix degenerate case with YouTube filter involving double hyphens.
193 Thanks Pierre Attar for reporting.
194 - Fix YouTube rendering problem on certain versions of Firefox.
195 - Fix CSSDefinition Printer problems with decorators
196 - Add text parameter to unit tests, forces text output
197 . Add verbose mode to command line test runner, use (--verbose)
198 . Turn on unit tests for UnitConverter
199 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
200 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
202 . Removed trailing whitespace from all text files, see
203 remote-trailing-whitespace.php maintenance script.
204 . Convert configuration to use property list backend.
206 3.2.0, released 2008-10-31
207 # Using %Core.CollectErrors forces line number/column tracking on, whereas
208 previously you could theoretically turn it off.
209 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
210 use handleEnd() instead.
211 ! %Output.AttrSort for when you need your attributes in alphabetical order to
212 deal with a bug in FCKEditor. Requested by frank farmer.
213 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
214 ! Proper support for name attribute. It is now allowed and equivalent to the id
215 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
216 is heavy (for all doctypes).
217 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
218 use on hand-written HTML.
219 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
220 the strategy to be used, standalone, on untrusted input.
221 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
222 processing of left angled brackets in smileys and other whatnot.
223 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
224 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
225 the --only-phpt parameter, although for backwards-compatibility the flag
227 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
228 Users who are not performing inbound filtering, this may seem a little
229 useless, but as a bonus, the test suite and handling of edge cases is also
231 ! Experimental implementation of forms for %HTML.Trusted
232 ! Track column numbers when maintain line numbers is on
233 ! Proprietary 'background' attribute on table-related elements converted into
234 corresponding CSS. Thanks Fusemail for sponsoring this feature!
235 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
237 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
238 time of operation varies slightly from notifyEnd() as *all* end tokens are
239 processed by the injector before they are subject to the well-formedness rules.
240 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
241 basename of image when not present.
242 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
243 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
244 the other involving an undefined $is_folder error.
245 - Throw error when %Core.Encoding is set to a spurious value. Previously,
246 this errored silently and returned false.
247 - Redirected stderr to stdout for flush error output.
248 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
250 - Do not re-munge URL if the output URL has the same host as the input URL.
252 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
253 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
254 - Fix bug with inline elements in blockquotes conflicting with strict doctype
255 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
256 - Fix bug where dots and double-dots in absolute URLs without hostname were
257 not collapsed by URIFilter_MakeAbsolute.
258 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
259 by reordering their addition.
260 - Will now throw exception on many error conditions during lexer creation; also
261 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
263 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
264 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
265 Reported by David Morton.
266 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
267 for more interesting filter-backtracking
268 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
269 index to reprocess tokens.
270 . StringHashParser now allows for multiline sections with "empty" content;
271 previously the section would remain undefined.
272 . Added --quick option to multitest.php, which tests only the most recent
273 release for each series.
274 . Added --distro option to multitest.php, which accepts either 'normal' or
275 'standalone'. This supercedes --exclude-normal and --exclude-standalone
277 3.1.1, released 2008-06-19
278 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
279 In order to enable this again, please set %URI.MungeResources to true.
280 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
281 and height/width HTML with %HTML.MaxImgLength.
282 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
283 for sponsoring this feature. Check out the corresponding documentation
284 for details. (Att Nightly testers: The API for this feature changed before
285 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
286 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
287 ! Implemented post URI filtering. Set member variable $post to true to set
289 ! Allow modules to define injectors via $info_injector. Injectors are
290 automatically disabled if injector's needed elements are not found.
291 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
292 Thanks Chris for sponsoring. If you've been using ad hoc code from the
293 forums, PLEASE use this instead.
294 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
295 embedded, tag name, attribute name, CSS property name). See %URI.Munge
296 for more details. Requested by Jochem Blok.
297 - Disable percent height/width attributes for img.
298 - AttrValidator operations are now atomic; updates to attributes are not
299 manifest in token until end of operations. This prevents naughty internal
300 code from directly modifying CurrentToken when they're not supposed to.
301 This semantics change was requested by frank farmer.
302 - Percent encoding checks enabled for URI query and fragment
303 - Fix stray backslashes in font-family; CSS Unicode character escapes are
304 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
306 - Improve parseCDATA algorithm to take into account newline normalization
307 - Account for browser confusion between Yen character and backslash in
308 Shift_JIS encoding. This fix generalizes to any other encoding which is not
309 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
310 - Fix missing configuration parameter in Generator calls. Thanks vs for the
312 - Improved adherence to Unicode by checking for non-character codepoints.
313 Thanks Geoffrey Sneddon for reporting. This may result in degraded
314 performance for extremely large inputs.
315 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
317 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
318 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
320 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
321 to __construct($min, $max). __construct(true) is equivalent to
323 . Added HTMLPurifier_AttrDef_Switch class
324 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
325 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
326 get this called with the configuration object. All modules now
327 use this rather than __construct(), although legacy code using constructors
328 will still work--the new format, however, lets modules access the
329 configuration object for HTML namespace dependant tweaks.
330 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
331 . ConfigSchema data-structure heavily optimized; on average it uses a third
332 the memory it did previously. The interface has changed accordingly,
333 consult changes to HTMLPurifier_Config for details.
334 . Variable parsing types now are magic integers instead of strings
335 . Added benchmark for ConfigSchema
336 . HTMLPurifier_Generator requires $config and $context parameters. If you
337 don't know what they should be, use HTMLPurifier_Config::createDefault()
338 and new HTMLPurifier_Context().
339 . Printers now properly distinguish between output configuration, and
340 target configuration. This is not applicable to scripts using
341 the Printers for HTML Purifier related tasks.
342 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
343 fatal errors will ensue.
344 . URIFilter->prepare can return false in order to abort loading of the filter
345 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
346 an external resource.
347 . %URI.Munge functionality factored out into a post-filter class.
348 . Added CurrentCSSProperty context variable during CSS validation
350 3.1.0, released 2008-05-18
351 # Unnecessary references to objects (vestiges of PHP4) removed from method
352 signatures. The following methods do not need references when assigning from
353 them and will result in E_STRICT errors if you try:
354 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
355 + HTMLPurifier_ConfigSchema::instance()
356 + HTMLPurifier_DefinitionCacheFactory::instance()
357 + HTMLPurifier_DefinitionCacheFactory->create()
358 + HTMLPurifier_DoctypeRegistry->register()
359 + HTMLPurifier_DoctypeRegistry->get()
360 + HTMLPurifier_HTMLModule->addElement()
361 + HTMLPurifier_HTMLModule->addBlankElement()
362 + HTMLPurifier_LanguageFactory::instance()
363 # Printer_ConfigForm's get*() functions were static-ified
364 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
365 form of tag@attr, NOT tag.attr (which will throw an error and won't do
366 anything). This is for forwards compatibility with XML; you'd do best
367 to migrate an %HTML.AllowedAttributes directives to this syntax too.
368 ! Allow index to be false for config from form creation
369 ! Added HTMLPurifier::VERSION constant
370 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
371 and allows for version numbers like "3.1.0-dev".
372 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
373 ! HTML Purifier's URI handling is a lot more robust, with much stricter
374 validation checks and better percent encoding handling. Thanks Gareth Heyes
375 for indicating security vulnerabilities from lax percent encoding.
376 ! Bootstrap autoloader deals more robustly with classes that don't exist,
377 preventing class_exists($class, true) from barfing.
378 - InterchangeBuilder now alphabetizes its lists
379 - Validation error in configdoc output fixed
380 - Iconv and other encoding errors muted even with custom error handlers that
381 do not honor error_reporting
382 - Add protection against imagecrash attack with CSS height/width
383 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
384 - Fixed and revamped broken ConfigForm smoketest
385 - Bug with bool/null fields in Printer_ConfigForm fixed
386 - Bug with global forbidden attributes fixed
387 - Improved error messages for allowed and forbidden HTML elements and attributes
388 - Missing (or null) in configdoc documentation restored
389 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
390 of DOM), HTML Purifier punts to DirectLex
391 - Fatal error with unserialization of ScriptRequired
392 - Created directories are now chmod'ed properly
393 - Fixed bug with fallback languages in LanguageFactory
394 - Standalone testing setup properly with autoload
395 . Out-of-date documentation revised
396 . UTF-8 encoding check optimization as suggested by Diego
397 . HTMLPurifier_Error removed in favor of exceptions
398 . More copy() function removed; should use clone instead
399 . More extensive unit tests for HTMLDefinition
400 . assertPurification moved to central harness
401 . HTMLPurifier_Generator accepts $config and $context parameters during
402 instantiation, not runtime
403 . Double-quotes outside of attribute values are now unescaped
405 3.1.0rc1, released 2008-04-22
406 # Autoload support added. Internal require_once's removed in favor of an
407 explicit require list or autoloading. To use HTML Purifier,
408 you must now either use HTMLPurifier.auto.php
409 or HTMLPurifier.includes.php; setting the include path and including
410 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
411 as well to register our autoload handler (or modify your autoload function
412 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
413 HTMLPurifier.safe-includes.php for a less performance friendly but more
414 user-friendly library load.
415 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
416 information is stored in the ConfigSchema directory, and the
417 maintenance/generate-schema-cache.php generates the schema.ser file, which
418 is now instantiated. Support for userland schema changes coming soon!
419 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
420 alias; to get rid of these errors just modify your configuration to use
421 the new directive name.
422 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
423 enabled using %Filter.$filter_name or by setting your own filters using
425 # Directive-level safety properties superceded in favor of module-level
426 safety. Internal method HTMLModule->addElement() has changed, although
427 the externally visible HTMLDefinition->addElement has *not* changed.
428 ! Extra utility classes for testing and non-library operations can
429 be found in extras/. Specifically, these are FSTools and ConfigDoc.
430 You may find a use for these in your own project, but right now they
431 are highly experimental and volatile.
432 ! Integration with PHPT allows for automated smoketests
433 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
434 by Chris. You can enable them with %HTML.Proprietary if your client
436 ! Support for !important CSS cascade modifier. By default, this will be stripped
437 from CSS, but you can enable it using %CSS.AllowImportant
438 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
440 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
441 Developer error (not enduser error) can cause these to be triggered.
442 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
443 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
444 mucking around with HTMLPurifier_CSSDefinition
445 ! ConfigDoc output has been enhanced with version and deprecation info.
446 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
447 - Autoclose now operates iteratively, i.e. <span><span><div> now has
448 both span tags closed.
449 - Various HTMLPurifier_Config convenience functions now accept another parameter
450 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
452 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
453 - Fix bug in ExtractStyleBlocks with comments in style tags
454 - Fix bug in comment parsing for DirectLex
455 - Flush output now displayed when in command line mode for unit tester
456 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
457 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
458 on the same element without emitting errors.
459 - Fixed fatal error in PH5P lexer with invalid tag names
460 . Plugins now get their own changelogs according to project conventions.
461 . Convert tokens to use instanceof, reducing memory footprint and
462 improving comparison speed.
463 . Dry runs now supported in SimpleTest; testing facilities improved
464 . Bootstrap class added for handling autoloading functionality
465 . Implemented recursive glob at FSTools->globr
466 . ConfigSchema now has instance methods for all corresponding define*
468 . A couple of new historical maintenance scripts were added.
469 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
470 . tests/index.php can now be run from any directory.
471 . HTMLPurifier_Token subclasses split into seperate files
472 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
473 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
474 . New --php=php flag added, allows PHP executable to be specified (command

509 %Filter.ExtractStyleBlocksScope
510 ! Experimental support for some proprietary CSS attributes allowed:
511 opacity (and all of the browser-specific equivalents) and scrollbar colors.
512 Enable by setting %CSS.Proprietary to true.

554 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
555 to better communicate its purpose
556 . Error unit tests can now specify the expectation of no errors. Future

580 ! CSS property border-spacing implemented
581 - Fix non-visible parsing error in DirectLex with empty tags that have
582 slashes inside attribute values.
583 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly

585 default for tables in most browsers. Thanks Brett Zamir for pointing
587 - Fix validation errors in configuration form

639 . ConfigForm generates textareas instead of text inputs for lists, hashes,
640 lookups, text and itext fields

666 linkify your HTML input by setting %AutoFormat.AutoParagraph and
667 %AutoFormat.Linkify to true

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