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 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
16 <yramirez-htmlpurifier@adicio.com> for reporting.
17 - Explicitly initialize anonModule variable to null.
18 - Do not duplicate nofollow if already present. Thanks 178
20 - Do not add nofollow if hostname matches our current host. Thanks 178
21 for reporting, and Neike Taika-Tessaro for helping diagnose.
22 - Do not unset parser variable; this fixes intermittent serialization
24 - Fix iconv truncation bug, where non-UTF-8 target encodings see
25 output truncated after around 8000 characters.
27 4.3.0, released 2011-03-27
28 # Fixed broken caching of customized raw definitions, but requires an
29 API change. The old API still works but will emit a warning,
30 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
31 for how to upgrade your code.
32 # Protect against Internet Explorer innerHTML behavior by specially
33 treating attributes with backticks but no angled brackets, quotes or
34 spaces. This constitutes a slight semantic change, which can be
35 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
37 # Protect against cssText/innerHTML by restricting allowed characters
38 used in fonts further than mandated by the specification and encoding
39 some extra special characters in URLs. Reported by Neike
40 Taika-Tessaro and Mario Heiderich.
41 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
42 ! More types of SPL autoloaders allowed on later versions of PHP.
43 ! Implementations for position, top, left, right, bottom, z-index
44 when %CSS.Trusted is on.
45 ! Add %Cache.SerializerPermissions option for custom serializer
46 directory/file permissions
47 ! Fix longstanding bug in Flash support for non-IE browsers, and
48 allow more wmode attributes.
49 ! Add %CSS.AllowedFonts to restrict permissible font names.
50 - Switch to an iterative traversal of the DOM, which prevents us
51 from running out of stack space for deeply nested documents.
52 Thanks Maxim Krizhanovsky for contributing a patch.
53 - Make removal of conditional IE comments ungreedy; thanks Bernd
55 - Escape CDATA before removing Internet Explorer comments.
56 - Fix removal of id attributes under certain conditions by ensuring
57 armor attributes are preserved when recreating tags.
58 - Check if schema.ser was corrupted.
59 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
60 This safety check is only done for HTMLPurifier.auto.php; if you
61 are using standalone or the specialized includes files, you're
62 expected to know what you're doing.
63 - Stop repeatedly writing the cache file after I'm done customizing a
64 raw definition. Reported by ajh.
65 - Switch to using require_once in the Bootstrap to work around bad
66 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
67 - Fix URI handling when hostname is missing but scheme is present.
68 Reported by Neike Taika-Tessaro.
69 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
71 - Fix harmless notice from indexing into empty string. Thanks Matthijs
72 Kooijman <matthijs@stdin.nl> for reporting.
73 - Don't autoclose no parent elements are able to support the element
74 that triggered the autoclose. In particular fixes strange behavior
75 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
76 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
78 4.2.0, released 2010-09-15
79 ! Added %Core.RemoveProcessingInstructions, which lets you remove
81 ! Added %URI.DisableResources functionality; the directive originally
82 did nothing. Thanks David Rothstein for reporting.
83 ! Add documentation about configuration directive types.
84 ! Add %CSS.ForbiddenProperties configuration directive.
85 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
86 to utilize full-screen mode.
87 ! Add optional support for the <code>file</code> URI scheme, enable
88 by explicitly setting %URI.AllowedSchemes.
89 ! Add %Core.NormalizeNewlines options to allow turning off newline
91 - Fix improper handling of Internet Explorer conditional comments
92 by parser. Thanks zmonteca for reporting.
93 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
94 Thanks sidepodcast for the fix.
95 - Warn if an element is allowed, but an attribute it requires is
98 4.1.1, released 2010-05-31
99 - Fix undefined index warnings in maintenance scripts.
100 - Fix bug in DirectLex for parsing elements with a single attribute
102 - Rewrite CSS output logic for font-family and url(). Thanks Mario
103 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
104 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
105 - Emit an error for CollectErrors if a body is extracted
106 - Fix bug where in background-position for center keyword handling.
107 - Fix infinite loop when a wrapper element is inserted in a context
108 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
109 - Remove +x bit and shebang from index.php; only supported mode is to
110 explicitly call it with php.
111 - Make test script less chatty when log_errors is on.
113 4.1.0, released 2010-04-26
114 ! Support proprietary height attribute on table element
115 ! Support YouTube slideshows that contain /cp/ in their URL.
116 ! Support for data: URI scheme; not enabled by default, add it using
118 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
119 ! Support for Internet Explorer compatibility with %HTML.SafeObject
120 using %Output.FlashCompat.
121 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
122 - Always quote the insides of url(...) in CSS.
124 4.0.0, released 2009-07-07
125 # APIs for ConfigSchema subsystem have substantially changed. See
126 docs/dev-config-bcbreaks.txt for details; in essence, anything that
127 had both namespace and directive now have a single unified key.
128 # Some configuration directives were renamed, specifically:
129 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
130 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
131 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
132 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
133 As usual, the old directive names will still work, but will throw E_NOTICE
135 # The allowed values for class have been relaxed to allow all of CDATA for
136 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
137 %Attr.ClassUseCDATA to false.
138 # Instead of appending the content model to an old content model, a blank
139 element will replace the old content model. You can use #SUPER to get
140 the old content model.
141 ! More robust support for name="" and id=""
142 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
143 configuration, and have changes to that configuration be propagated
144 to all of its children.
145 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
146 the name attribute when set. Use with care. Thanks Ian Cook for
148 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
149 tags that contain non-breaking spaces as well other whitespace. You
150 can also modify which tags should have maintained with
151 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
152 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
153 classes users can use to a specified finite set of classes, and
154 %Attr.ForbiddenClasses, which is the logical inverse.
155 ! You can now maintain your own configuration schema directories by
156 creating a config-schema.php file or passing an extra argument. Check
157 docs/dev-config-schema.html for more details.
158 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
159 your configuration in a compact serial file, which you can unserialize
160 and use directly without having to go through the overhead of setup.
161 - Fix bug where URIDefinition would not get cleared if it's directives got
163 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
164 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
165 - Make %URI.Munge not apply to links that have the same host as your host.
166 - Prevent stray </body> tag from truncating output, if a second </body>
168 . Created script maintenance/rename-config.php for renaming a configuration
169 directive while maintaining its alias. This script does not change source code.
170 . Implement namespace locking for definition construction, to prevent
171 bugs where a directive is used for definition construction but is not
172 used to construct the cache hash.
174 3.3.0, released 2009-02-16
175 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
176 ! Implement generic property list classess
177 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
178 does not do the "right thing" with characters not supported in the output
180 - Spellcheck UTF-8: The Secret To Character Encoding
181 - Fix improper removal of the contents of elements with only whitespace. Thanks
182 Eric Wald for reporting.
183 - Fix broken test suite in versions of PHP without spl_autoload_register()
184 - Fix degenerate case with YouTube filter involving double hyphens.
185 Thanks Pierre Attar for reporting.
186 - Fix YouTube rendering problem on certain versions of Firefox.
187 - Fix CSSDefinition Printer problems with decorators
188 - Add text parameter to unit tests, forces text output
189 . Add verbose mode to command line test runner, use (--verbose)
190 . Turn on unit tests for UnitConverter
191 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
192 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
194 . Removed trailing whitespace from all text files, see
195 remote-trailing-whitespace.php maintenance script.
196 . Convert configuration to use property list backend.
198 3.2.0, released 2008-10-31
199 # Using %Core.CollectErrors forces line number/column tracking on, whereas
200 previously you could theoretically turn it off.
201 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
202 use handleEnd() instead.
203 ! %Output.AttrSort for when you need your attributes in alphabetical order to
204 deal with a bug in FCKEditor. Requested by frank farmer.
205 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
206 ! Proper support for name attribute. It is now allowed and equivalent to the id
207 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
208 is heavy (for all doctypes).
209 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
210 use on hand-written HTML.
211 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
212 the strategy to be used, standalone, on untrusted input.
213 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
214 processing of left angled brackets in smileys and other whatnot.
215 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
216 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
217 the --only-phpt parameter, although for backwards-compatibility the flag
219 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
220 Users who are not performing inbound filtering, this may seem a little
221 useless, but as a bonus, the test suite and handling of edge cases is also
223 ! Experimental implementation of forms for %HTML.Trusted
224 ! Track column numbers when maintain line numbers is on
225 ! Proprietary 'background' attribute on table-related elements converted into
226 corresponding CSS. Thanks Fusemail for sponsoring this feature!
227 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
229 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
230 time of operation varies slightly from notifyEnd() as *all* end tokens are
231 processed by the injector before they are subject to the well-formedness rules.
232 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
233 basename of image when not present.
234 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
235 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
236 the other involving an undefined $is_folder error.
237 - Throw error when %Core.Encoding is set to a spurious value. Previously,
238 this errored silently and returned false.
239 - Redirected stderr to stdout for flush error output.
240 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
242 - Do not re-munge URL if the output URL has the same host as the input URL.
244 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
245 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
246 - Fix bug with inline elements in blockquotes conflicting with strict doctype
247 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
248 - Fix bug where dots and double-dots in absolute URLs without hostname were
249 not collapsed by URIFilter_MakeAbsolute.
250 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
251 by reordering their addition.
252 - Will now throw exception on many error conditions during lexer creation; also
253 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
255 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
256 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
257 Reported by David Morton.
258 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
259 for more interesting filter-backtracking
260 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
261 index to reprocess tokens.
262 . StringHashParser now allows for multiline sections with "empty" content;
263 previously the section would remain undefined.
264 . Added --quick option to multitest.php, which tests only the most recent
265 release for each series.
266 . Added --distro option to multitest.php, which accepts either 'normal' or
267 'standalone'. This supercedes --exclude-normal and --exclude-standalone
269 3.1.1, released 2008-06-19
270 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
271 In order to enable this again, please set %URI.MungeResources to true.
272 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
273 and height/width HTML with %HTML.MaxImgLength.
274 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
275 for sponsoring this feature. Check out the corresponding documentation
276 for details. (Att Nightly testers: The API for this feature changed before
277 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
278 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
279 ! Implemented post URI filtering. Set member variable $post to true to set
281 ! Allow modules to define injectors via $info_injector. Injectors are
282 automatically disabled if injector's needed elements are not found.
283 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
284 Thanks Chris for sponsoring. If you've been using ad hoc code from the
285 forums, PLEASE use this instead.
286 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
287 embedded, tag name, attribute name, CSS property name). See %URI.Munge
288 for more details. Requested by Jochem Blok.
289 - Disable percent height/width attributes for img.
290 - AttrValidator operations are now atomic; updates to attributes are not
291 manifest in token until end of operations. This prevents naughty internal
292 code from directly modifying CurrentToken when they're not supposed to.
293 This semantics change was requested by frank farmer.
294 - Percent encoding checks enabled for URI query and fragment
295 - Fix stray backslashes in font-family; CSS Unicode character escapes are
296 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
298 - Improve parseCDATA algorithm to take into account newline normalization
299 - Account for browser confusion between Yen character and backslash in
300 Shift_JIS encoding. This fix generalizes to any other encoding which is not
301 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
302 - Fix missing configuration parameter in Generator calls. Thanks vs for the
304 - Improved adherence to Unicode by checking for non-character codepoints.
305 Thanks Geoffrey Sneddon for reporting. This may result in degraded
306 performance for extremely large inputs.
307 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
309 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
310 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
312 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
313 to __construct($min, $max). __construct(true) is equivalent to
315 . Added HTMLPurifier_AttrDef_Switch class
316 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
317 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
318 get this called with the configuration object. All modules now
319 use this rather than __construct(), although legacy code using constructors
320 will still work--the new format, however, lets modules access the
321 configuration object for HTML namespace dependant tweaks.
322 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
323 . ConfigSchema data-structure heavily optimized; on average it uses a third
324 the memory it did previously. The interface has changed accordingly,
325 consult changes to HTMLPurifier_Config for details.
326 . Variable parsing types now are magic integers instead of strings
327 . Added benchmark for ConfigSchema
328 . HTMLPurifier_Generator requires $config and $context parameters. If you
329 don't know what they should be, use HTMLPurifier_Config::createDefault()
330 and new HTMLPurifier_Context().
331 . Printers now properly distinguish between output configuration, and
332 target configuration. This is not applicable to scripts using
333 the Printers for HTML Purifier related tasks.
334 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
335 fatal errors will ensue.
336 . URIFilter->prepare can return false in order to abort loading of the filter
337 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
338 an external resource.
339 . %URI.Munge functionality factored out into a post-filter class.
340 . Added CurrentCSSProperty context variable during CSS validation
342 3.1.0, released 2008-05-18
343 # Unnecessary references to objects (vestiges of PHP4) removed from method
344 signatures. The following methods do not need references when assigning from
345 them and will result in E_STRICT errors if you try:
346 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
347 + HTMLPurifier_ConfigSchema::instance()
348 + HTMLPurifier_DefinitionCacheFactory::instance()
349 + HTMLPurifier_DefinitionCacheFactory->create()
350 + HTMLPurifier_DoctypeRegistry->register()
351 + HTMLPurifier_DoctypeRegistry->get()
352 + HTMLPurifier_HTMLModule->addElement()
353 + HTMLPurifier_HTMLModule->addBlankElement()
354 + HTMLPurifier_LanguageFactory::instance()
355 # Printer_ConfigForm's get*() functions were static-ified
356 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
357 form of tag@attr, NOT tag.attr (which will throw an error and won't do
358 anything). This is for forwards compatibility with XML; you'd do best
359 to migrate an %HTML.AllowedAttributes directives to this syntax too.
360 ! Allow index to be false for config from form creation
361 ! Added HTMLPurifier::VERSION constant
362 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
363 and allows for version numbers like "3.1.0-dev".
364 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
365 ! HTML Purifier's URI handling is a lot more robust, with much stricter
366 validation checks and better percent encoding handling. Thanks Gareth Heyes
367 for indicating security vulnerabilities from lax percent encoding.
368 ! Bootstrap autoloader deals more robustly with classes that don't exist,
369 preventing class_exists($class, true) from barfing.
370 - InterchangeBuilder now alphabetizes its lists
371 - Validation error in configdoc output fixed
372 - Iconv and other encoding errors muted even with custom error handlers that
373 do not honor error_reporting
374 - Add protection against imagecrash attack with CSS height/width
375 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
376 - Fixed and revamped broken ConfigForm smoketest
377 - Bug with bool/null fields in Printer_ConfigForm fixed
378 - Bug with global forbidden attributes fixed
379 - Improved error messages for allowed and forbidden HTML elements and attributes
380 - Missing (or null) in configdoc documentation restored
381 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
382 of DOM), HTML Purifier punts to DirectLex
383 - Fatal error with unserialization of ScriptRequired
384 - Created directories are now chmod'ed properly
385 - Fixed bug with fallback languages in LanguageFactory
386 - Standalone testing setup properly with autoload
387 . Out-of-date documentation revised
388 . UTF-8 encoding check optimization as suggested by Diego
389 . HTMLPurifier_Error removed in favor of exceptions
390 . More copy() function removed; should use clone instead
391 . More extensive unit tests for HTMLDefinition
392 . assertPurification moved to central harness
393 . HTMLPurifier_Generator accepts $config and $context parameters during
394 instantiation, not runtime
395 . Double-quotes outside of attribute values are now unescaped
397 3.1.0rc1, released 2008-04-22
398 # Autoload support added. Internal require_once's removed in favor of an
399 explicit require list or autoloading. To use HTML Purifier,
400 you must now either use HTMLPurifier.auto.php
401 or HTMLPurifier.includes.php; setting the include path and including
402 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
403 as well to register our autoload handler (or modify your autoload function
404 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
405 HTMLPurifier.safe-includes.php for a less performance friendly but more
406 user-friendly library load.
407 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
408 information is stored in the ConfigSchema directory, and the
409 maintenance/generate-schema-cache.php generates the schema.ser file, which
410 is now instantiated. Support for userland schema changes coming soon!
411 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
412 alias; to get rid of these errors just modify your configuration to use
413 the new directive name.
414 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
415 enabled using %Filter.$filter_name or by setting your own filters using
417 # Directive-level safety properties superceded in favor of module-level
418 safety. Internal method HTMLModule->addElement() has changed, although
419 the externally visible HTMLDefinition->addElement has *not* changed.
420 ! Extra utility classes for testing and non-library operations can
421 be found in extras/. Specifically, these are FSTools and ConfigDoc.
422 You may find a use for these in your own project, but right now they
423 are highly experimental and volatile.
424 ! Integration with PHPT allows for automated smoketests
425 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
426 by Chris. You can enable them with %HTML.Proprietary if your client
428 ! Support for !important CSS cascade modifier. By default, this will be stripped
429 from CSS, but you can enable it using %CSS.AllowImportant
430 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
432 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
433 Developer error (not enduser error) can cause these to be triggered.
434 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
435 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
436 mucking around with HTMLPurifier_CSSDefinition
437 ! ConfigDoc output has been enhanced with version and deprecation info.
438 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
439 - Autoclose now operates iteratively, i.e. <span><span><div> now has
440 both span tags closed.
441 - Various HTMLPurifier_Config convenience functions now accept another parameter
442 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
444 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
445 - Fix bug in ExtractStyleBlocks with comments in style tags
446 - Fix bug in comment parsing for DirectLex
447 - Flush output now displayed when in command line mode for unit tester
448 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
449 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
450 on the same element without emitting errors.
451 - Fixed fatal error in PH5P lexer with invalid tag names
452 . Plugins now get their own changelogs according to project conventions.
453 . Convert tokens to use instanceof, reducing memory footprint and
454 improving comparison speed.
455 . Dry runs now supported in SimpleTest; testing facilities improved
456 . Bootstrap class added for handling autoloading functionality
457 . Implemented recursive glob at FSTools->globr
458 . ConfigSchema now has instance methods for all corresponding define*
460 . A couple of new historical maintenance scripts were added.
461 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
462 . tests/index.php can now be run from any directory.
463 . HTMLPurifier_Token subclasses split into seperate files
464 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
465 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
466 . New --php=php flag added, allows PHP executable to be specified (command
468 . htmlpurifier_add_test() preferred method to translate test files in to
469 classes, because it handles PHPT files too.
470 . Debugger class is deprecated and will be removed soon.
471 . Command line argument parsing for testing scripts revamped, now --opt value
473 . Smoketests now cleanup after magic quotes
474 . Generator now can output comments (however, comments are still stripped
475 from HTML Purifier output)
476 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
477 HTMLPurifier_VarParser->parse()

501 %Filter.ExtractStyleBlocksScope
502 ! Experimental support for some proprietary CSS attributes allowed:
503 opacity (and all of the browser-specific equivalents) and scrollbar colors.
504 Enable by setting %CSS.Proprietary to true.
505 - Colors missing # but in hex form will be corrected
506 - CSS Number algorithm improved

546 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
547 to better communicate its purpose
548 . Error unit tests can now specify the expectation of no errors. Future

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

658 linkify your HTML input by setting %AutoFormat.AutoParagraph and
659 %AutoFormat.Linkify to true

661 value of PHP_EOL. If this is not desired, set your newline format
662 using %Output.Newline.
663 ! Beta error collection, messages are implemented for the most generic

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