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.
18 4.3.0, released 2011-03-27
19 # Fixed broken caching of customized raw definitions, but requires an
20 API change. The old API still works but will emit a warning,
21 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
22 for how to upgrade your code.
23 # Protect against Internet Explorer innerHTML behavior by specially
24 treating attributes with backticks but no angled brackets, quotes or
25 spaces. This constitutes a slight semantic change, which can be
26 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
28 # Protect against cssText/innerHTML by restricting allowed characters
29 used in fonts further than mandated by the specification and encoding
30 some extra special characters in URLs. Reported by Neike
31 Taika-Tessaro and Mario Heiderich.
32 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
33 ! More types of SPL autoloaders allowed on later versions of PHP.
34 ! Implementations for position, top, left, right, bottom, z-index
35 when %CSS.Trusted is on.
36 ! Add %Cache.SerializerPermissions option for custom serializer
37 directory/file permissions
38 ! Fix longstanding bug in Flash support for non-IE browsers, and
39 allow more wmode attributes.
40 ! Add %CSS.AllowedFonts to restrict permissible font names.
41 ! Add %HTML.SafeIframe and %URI.IframeWhitelistRegexp for allowing
42 the iframe tag with whitelisted URIs.
43 - Switch to an iterative traversal of the DOM, which prevents us
44 from running out of stack space for deeply nested documents.
45 Thanks Maxim Krizhanovsky for contributing a patch.
46 - Make removal of conditional IE comments ungreedy; thanks Bernd
48 - Escape CDATA before removing Internet Explorer comments.
49 - Fix removal of id attributes under certain conditions by ensuring
50 armor attributes are preserved when recreating tags.
51 - Check if schema.ser was corrupted.
52 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
53 This safety check is only done for HTMLPurifier.auto.php; if you
54 are using standalone or the specialized includes files, you're
55 expected to know what you're doing.
56 - Stop repeatedly writing the cache file after I'm done customizing a
57 raw definition. Reported by ajh.
58 - Switch to using require_once in the Bootstrap to work around bad
59 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
60 - Fix URI handling when hostname is missing but scheme is present.
61 Reported by Neike Taika-Tessaro.
62 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
64 - Fix harmless notice from indexing into empty string. Thanks Matthijs
65 Kooijman <matthijs@stdin.nl> for reporting.
66 - Don't autoclose no parent elements are able to support the element
67 that triggered the autoclose. In particular fixes strange behavior
68 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
69 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
71 4.2.0, released 2010-09-15
72 ! Added %Core.RemoveProcessingInstructions, which lets you remove
74 ! Added %URI.DisableResources functionality; the directive originally
75 did nothing. Thanks David Rothstein for reporting.
76 ! Add documentation about configuration directive types.
77 ! Add %CSS.ForbiddenProperties configuration directive.
78 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
79 to utilize full-screen mode.
80 ! Add optional support for the <code>file</code> URI scheme, enable
81 by explicitly setting %URI.AllowedSchemes.
82 ! Add %Core.NormalizeNewlines options to allow turning off newline
84 - Fix improper handling of Internet Explorer conditional comments
85 by parser. Thanks zmonteca for reporting.
86 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
87 Thanks sidepodcast for the fix.
88 - Warn if an element is allowed, but an attribute it requires is
91 4.1.1, released 2010-05-31
92 - Fix undefined index warnings in maintenance scripts.
93 - Fix bug in DirectLex for parsing elements with a single attribute
95 - Rewrite CSS output logic for font-family and url(). Thanks Mario
96 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
97 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
98 - Emit an error for CollectErrors if a body is extracted
99 - Fix bug where in background-position for center keyword handling.
100 - Fix infinite loop when a wrapper element is inserted in a context
101 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
102 - Remove +x bit and shebang from index.php; only supported mode is to
103 explicitly call it with php.
104 - Make test script less chatty when log_errors is on.
106 4.1.0, released 2010-04-26
107 ! Support proprietary height attribute on table element
108 ! Support YouTube slideshows that contain /cp/ in their URL.
109 ! Support for data: URI scheme; not enabled by default, add it using
111 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
112 ! Support for Internet Explorer compatibility with %HTML.SafeObject
113 using %Output.FlashCompat.
114 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
115 - Always quote the insides of url(...) in CSS.
117 4.0.0, released 2009-07-07
118 # APIs for ConfigSchema subsystem have substantially changed. See
119 docs/dev-config-bcbreaks.txt for details; in essence, anything that
120 had both namespace and directive now have a single unified key.
121 # Some configuration directives were renamed, specifically:
122 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
123 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
124 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
125 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
126 As usual, the old directive names will still work, but will throw E_NOTICE
128 # The allowed values for class have been relaxed to allow all of CDATA for
129 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
130 %Attr.ClassUseCDATA to false.
131 # Instead of appending the content model to an old content model, a blank
132 element will replace the old content model. You can use #SUPER to get
133 the old content model.
134 ! More robust support for name="" and id=""
135 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
136 configuration, and have changes to that configuration be propagated
137 to all of its children.
138 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
139 the name attribute when set. Use with care. Thanks Ian Cook for
141 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
142 tags that contain non-breaking spaces as well other whitespace. You
143 can also modify which tags should have maintained with
144 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
145 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
146 classes users can use to a specified finite set of classes, and
147 %Attr.ForbiddenClasses, which is the logical inverse.
148 ! You can now maintain your own configuration schema directories by
149 creating a config-schema.php file or passing an extra argument. Check
150 docs/dev-config-schema.html for more details.
151 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
152 your configuration in a compact serial file, which you can unserialize
153 and use directly without having to go through the overhead of setup.
154 - Fix bug where URIDefinition would not get cleared if it's directives got
156 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
157 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
158 - Make %URI.Munge not apply to links that have the same host as your host.
159 - Prevent stray </body> tag from truncating output, if a second </body>
161 . Created script maintenance/rename-config.php for renaming a configuration
162 directive while maintaining its alias. This script does not change source code.
163 . Implement namespace locking for definition construction, to prevent
164 bugs where a directive is used for definition construction but is not
165 used to construct the cache hash.
167 3.3.0, released 2009-02-16
168 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
169 ! Implement generic property list classess
170 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
171 does not do the "right thing" with characters not supported in the output
173 - Spellcheck UTF-8: The Secret To Character Encoding
174 - Fix improper removal of the contents of elements with only whitespace. Thanks
175 Eric Wald for reporting.
176 - Fix broken test suite in versions of PHP without spl_autoload_register()
177 - Fix degenerate case with YouTube filter involving double hyphens.
178 Thanks Pierre Attar for reporting.
179 - Fix YouTube rendering problem on certain versions of Firefox.
180 - Fix CSSDefinition Printer problems with decorators
181 - Add text parameter to unit tests, forces text output
182 . Add verbose mode to command line test runner, use (--verbose)
183 . Turn on unit tests for UnitConverter
184 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
185 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
187 . Removed trailing whitespace from all text files, see
188 remote-trailing-whitespace.php maintenance script.
189 . Convert configuration to use property list backend.
191 3.2.0, released 2008-10-31
192 # Using %Core.CollectErrors forces line number/column tracking on, whereas
193 previously you could theoretically turn it off.
194 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
195 use handleEnd() instead.
196 ! %Output.AttrSort for when you need your attributes in alphabetical order to
197 deal with a bug in FCKEditor. Requested by frank farmer.
198 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
199 ! Proper support for name attribute. It is now allowed and equivalent to the id
200 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
201 is heavy (for all doctypes).
202 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
203 use on hand-written HTML.
204 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
205 the strategy to be used, standalone, on untrusted input.
206 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
207 processing of left angled brackets in smileys and other whatnot.
208 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
209 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
210 the --only-phpt parameter, although for backwards-compatibility the flag
212 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
213 Users who are not performing inbound filtering, this may seem a little
214 useless, but as a bonus, the test suite and handling of edge cases is also
216 ! Experimental implementation of forms for %HTML.Trusted
217 ! Track column numbers when maintain line numbers is on
218 ! Proprietary 'background' attribute on table-related elements converted into
219 corresponding CSS. Thanks Fusemail for sponsoring this feature!
220 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
222 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
223 time of operation varies slightly from notifyEnd() as *all* end tokens are
224 processed by the injector before they are subject to the well-formedness rules.
225 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
226 basename of image when not present.
227 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
228 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
229 the other involving an undefined $is_folder error.
230 - Throw error when %Core.Encoding is set to a spurious value. Previously,
231 this errored silently and returned false.
232 - Redirected stderr to stdout for flush error output.
233 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
235 - Do not re-munge URL if the output URL has the same host as the input URL.
237 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
238 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
239 - Fix bug with inline elements in blockquotes conflicting with strict doctype
240 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
241 - Fix bug where dots and double-dots in absolute URLs without hostname were
242 not collapsed by URIFilter_MakeAbsolute.
243 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
244 by reordering their addition.
245 - Will now throw exception on many error conditions during lexer creation; also
246 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
248 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
249 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
250 Reported by David Morton.
251 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
252 for more interesting filter-backtracking
253 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
254 index to reprocess tokens.
255 . StringHashParser now allows for multiline sections with "empty" content;
256 previously the section would remain undefined.
257 . Added --quick option to multitest.php, which tests only the most recent
258 release for each series.
259 . Added --distro option to multitest.php, which accepts either 'normal' or
260 'standalone'. This supercedes --exclude-normal and --exclude-standalone
262 3.1.1, released 2008-06-19
263 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
264 In order to enable this again, please set %URI.MungeResources to true.
265 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
266 and height/width HTML with %HTML.MaxImgLength.
267 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
268 for sponsoring this feature. Check out the corresponding documentation
269 for details. (Att Nightly testers: The API for this feature changed before
270 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
271 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
272 ! Implemented post URI filtering. Set member variable $post to true to set
274 ! Allow modules to define injectors via $info_injector. Injectors are
275 automatically disabled if injector's needed elements are not found.
276 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
277 Thanks Chris for sponsoring. If you've been using ad hoc code from the
278 forums, PLEASE use this instead.
279 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
280 embedded, tag name, attribute name, CSS property name). See %URI.Munge
281 for more details. Requested by Jochem Blok.
282 - Disable percent height/width attributes for img.
283 - AttrValidator operations are now atomic; updates to attributes are not
284 manifest in token until end of operations. This prevents naughty internal
285 code from directly modifying CurrentToken when they're not supposed to.
286 This semantics change was requested by frank farmer.
287 - Percent encoding checks enabled for URI query and fragment
288 - Fix stray backslashes in font-family; CSS Unicode character escapes are
289 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
291 - Improve parseCDATA algorithm to take into account newline normalization
292 - Account for browser confusion between Yen character and backslash in
293 Shift_JIS encoding. This fix generalizes to any other encoding which is not
294 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
295 - Fix missing configuration parameter in Generator calls. Thanks vs for the
297 - Improved adherence to Unicode by checking for non-character codepoints.
298 Thanks Geoffrey Sneddon for reporting. This may result in degraded
299 performance for extremely large inputs.
300 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
302 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
303 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
305 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
306 to __construct($min, $max). __construct(true) is equivalent to
308 . Added HTMLPurifier_AttrDef_Switch class
309 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
310 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
311 get this called with the configuration object. All modules now
312 use this rather than __construct(), although legacy code using constructors
313 will still work--the new format, however, lets modules access the
314 configuration object for HTML namespace dependant tweaks.
315 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
316 . ConfigSchema data-structure heavily optimized; on average it uses a third
317 the memory it did previously. The interface has changed accordingly,
318 consult changes to HTMLPurifier_Config for details.
319 . Variable parsing types now are magic integers instead of strings
320 . Added benchmark for ConfigSchema
321 . HTMLPurifier_Generator requires $config and $context parameters. If you
322 don't know what they should be, use HTMLPurifier_Config::createDefault()
323 and new HTMLPurifier_Context().
324 . Printers now properly distinguish between output configuration, and
325 target configuration. This is not applicable to scripts using
326 the Printers for HTML Purifier related tasks.
327 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
328 fatal errors will ensue.
329 . URIFilter->prepare can return false in order to abort loading of the filter
330 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
331 an external resource.
332 . %URI.Munge functionality factored out into a post-filter class.
333 . Added CurrentCSSProperty context variable during CSS validation
335 3.1.0, released 2008-05-18
336 # Unnecessary references to objects (vestiges of PHP4) removed from method
337 signatures. The following methods do not need references when assigning from
338 them and will result in E_STRICT errors if you try:
339 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
340 + HTMLPurifier_ConfigSchema::instance()
341 + HTMLPurifier_DefinitionCacheFactory::instance()
342 + HTMLPurifier_DefinitionCacheFactory->create()
343 + HTMLPurifier_DoctypeRegistry->register()
344 + HTMLPurifier_DoctypeRegistry->get()
345 + HTMLPurifier_HTMLModule->addElement()
346 + HTMLPurifier_HTMLModule->addBlankElement()
347 + HTMLPurifier_LanguageFactory::instance()
348 # Printer_ConfigForm's get*() functions were static-ified
349 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
350 form of tag@attr, NOT tag.attr (which will throw an error and won't do
351 anything). This is for forwards compatibility with XML; you'd do best
352 to migrate an %HTML.AllowedAttributes directives to this syntax too.
353 ! Allow index to be false for config from form creation
354 ! Added HTMLPurifier::VERSION constant
355 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
356 and allows for version numbers like "3.1.0-dev".
357 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
358 ! HTML Purifier's URI handling is a lot more robust, with much stricter
359 validation checks and better percent encoding handling. Thanks Gareth Heyes
360 for indicating security vulnerabilities from lax percent encoding.
361 ! Bootstrap autoloader deals more robustly with classes that don't exist,
362 preventing class_exists($class, true) from barfing.
363 - InterchangeBuilder now alphabetizes its lists
364 - Validation error in configdoc output fixed
365 - Iconv and other encoding errors muted even with custom error handlers that
366 do not honor error_reporting
367 - Add protection against imagecrash attack with CSS height/width
368 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
369 - Fixed and revamped broken ConfigForm smoketest
370 - Bug with bool/null fields in Printer_ConfigForm fixed
371 - Bug with global forbidden attributes fixed
372 - Improved error messages for allowed and forbidden HTML elements and attributes
373 - Missing (or null) in configdoc documentation restored
374 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
375 of DOM), HTML Purifier punts to DirectLex
376 - Fatal error with unserialization of ScriptRequired
377 - Created directories are now chmod'ed properly
378 - Fixed bug with fallback languages in LanguageFactory
379 - Standalone testing setup properly with autoload
380 . Out-of-date documentation revised
381 . UTF-8 encoding check optimization as suggested by Diego
382 . HTMLPurifier_Error removed in favor of exceptions
383 . More copy() function removed; should use clone instead
384 . More extensive unit tests for HTMLDefinition
385 . assertPurification moved to central harness
386 . HTMLPurifier_Generator accepts $config and $context parameters during
387 instantiation, not runtime
388 . Double-quotes outside of attribute values are now unescaped
390 3.1.0rc1, released 2008-04-22
391 # Autoload support added. Internal require_once's removed in favor of an
392 explicit require list or autoloading. To use HTML Purifier,
393 you must now either use HTMLPurifier.auto.php
394 or HTMLPurifier.includes.php; setting the include path and including
395 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
396 as well to register our autoload handler (or modify your autoload function
397 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
398 HTMLPurifier.safe-includes.php for a less performance friendly but more
399 user-friendly library load.
400 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
401 information is stored in the ConfigSchema directory, and the
402 maintenance/generate-schema-cache.php generates the schema.ser file, which
403 is now instantiated. Support for userland schema changes coming soon!
404 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
405 alias; to get rid of these errors just modify your configuration to use
406 the new directive name.
407 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
408 enabled using %Filter.$filter_name or by setting your own filters using
410 # Directive-level safety properties superceded in favor of module-level
411 safety. Internal method HTMLModule->addElement() has changed, although
412 the externally visible HTMLDefinition->addElement has *not* changed.
413 ! Extra utility classes for testing and non-library operations can
414 be found in extras/. Specifically, these are FSTools and ConfigDoc.
415 You may find a use for these in your own project, but right now they
416 are highly experimental and volatile.
417 ! Integration with PHPT allows for automated smoketests
418 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
419 by Chris. You can enable them with %HTML.Proprietary if your client
421 ! Support for !important CSS cascade modifier. By default, this will be stripped
422 from CSS, but you can enable it using %CSS.AllowImportant
423 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
425 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
426 Developer error (not enduser error) can cause these to be triggered.
427 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
428 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
429 mucking around with HTMLPurifier_CSSDefinition
430 ! ConfigDoc output has been enhanced with version and deprecation info.
431 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
432 - Autoclose now operates iteratively, i.e. <span><span><div> now has
433 both span tags closed.
434 - Various HTMLPurifier_Config convenience functions now accept another parameter
435 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
437 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
438 - Fix bug in ExtractStyleBlocks with comments in style tags
439 - Fix bug in comment parsing for DirectLex
440 - Flush output now displayed when in command line mode for unit tester
441 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
442 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
443 on the same element without emitting errors.
444 - Fixed fatal error in PH5P lexer with invalid tag names
445 . Plugins now get their own changelogs according to project conventions.
446 . Convert tokens to use instanceof, reducing memory footprint and
447 improving comparison speed.
448 . Dry runs now supported in SimpleTest; testing facilities improved
449 . Bootstrap class added for handling autoloading functionality
450 . Implemented recursive glob at FSTools->globr
451 . ConfigSchema now has instance methods for all corresponding define*
453 . A couple of new historical maintenance scripts were added.
454 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
455 . tests/index.php can now be run from any directory.
456 . HTMLPurifier_Token subclasses split into seperate files
457 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
458 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
459 . New --php=php flag added, allows PHP executable to be specified (command
461 . htmlpurifier_add_test() preferred method to translate test files in to
462 classes, because it handles PHPT files too.
463 . Debugger class is deprecated and will be removed soon.
464 . Command line argument parsing for testing scripts revamped, now --opt value
466 . Smoketests now cleanup after magic quotes
467 . Generator now can output comments (however, comments are still stripped
468 from HTML Purifier output)
469 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
470 HTMLPurifier_VarParser->parse()
471 . Integers auto-cast into float type by VarParser.
472 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
473 during cache generation
474 . Reordered script calls in maintenance/flush.php
475 . Command line scripts now honor exit codes
476 . When --flush fails in unit testers, abort tests and print message

493 The output CSS can also be "scoped" for a specific element, use:
494 %Filter.ExtractStyleBlocksScope
495 ! Experimental support for some proprietary CSS attributes allowed:
496 opacity (and all of the browser-specific equivalents) and scrollbar colors.
497 Enable by setting %CSS.Proprietary to true.
498 - Colors missing # but in hex form will be corrected
499 - CSS Number algorithm improved
500 - Unit testing and multi-testing now on steroids: command lines,

514 - Injector algorithm further refined: off-by-one error regarding skip
515 counts for dormant injectors fixed
516 - Corrective blockquote definition now enabled for HTML 4.01 Strict

522 allowing paragraph tags clarified: only inline content delimeted by
523 double newlines (not block elements) are paragraphed.
524 - Buggy treatment of end tags of elements that have required attributes
525 fixed (does not manifest on default tag-set)
526 - Spurious internal content reorganization error suppressed

538 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
539 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
540 to better communicate its purpose
541 . Error unit tests can now specify the expectation of no errors. Future
542 iterations of the harness will be extremely strict about what errors

563 Note that this Lexer introduces some classes not in the HTMLPurifier
564 namespace. Also, this is PHP5 only.
565 ! CSS property border-spacing implemented
566 - Fix non-visible parsing error in DirectLex with empty tags that have
567 slashes inside attribute values.
568 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly

570 default for tables in most browsers. Thanks Brett Zamir for pointing
572 - Fix validation errors in configuration form
573 - Hammer out a bunch of edge-case bugs in the standalone distribution
574 - Inclusion reflection removed from URISchemeRegistry; you must manually
575 include any new schema files you wish to use

577 . Unit test refactoring for one logical test per test function
578 . Config and context parameters in ComplexHarness deprecated: instead, edit
579 the $config and $context member variables

617 for output cache invalidation
618 . ConfigForm printer now can retrieve CSS and JS files as strings, in
619 case HTML Purifier's directory is not publically accessible
620 . Introduce new text/itext configuration directive values: these represent
621 longer strings that would be more appropriately edited with a textarea

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

627 be used to customize this behavior, by default <script> and <style> are
629 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
630 . Custom ChildDef added to default include list
631 . URIScheme reflection improved: will not attempt to include file if class

648 ! Tag auto-closing now based on a ChildDef heuristic rather than a
649 manually set auto_close array; some behavior may change
650 ! Experimental AutoFormat functionality added: auto-paragraph and
651 linkify your HTML input by setting %AutoFormat.AutoParagraph and
652 %AutoFormat.Linkify to true
653 ! Newlines normalized internally, and then converted back to the
654 value of PHP_EOL. If this is not desired, set your newline format
655 using %Output.Newline.
656 ! Beta error collection, messages are implemented for the most generic
657 cases involving Lexing or Strategies

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