4 = KEY ====================
10 ==========================
12 4.7.0, unknown release date
13 # opacity is now considered a "tricky" CSS property rather than a
15 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
16 an element should be considered "empty" (maybe preserve if it
17 has attributes), and modify iframe support so that the iframe
18 is removed if it is missing a src attribute. Thanks meeva for
20 - Don't truncate upon encountering </div> when using DOMLex. Thanks
21 Myrto Christina for finally convincing me to fix this.
22 - Update YouTube filter for new code.
23 - Fix parsing of rgb() values with spaces in them for 'border'
26 4.6.0, released 2013-11-30
27 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
28 Please update any verification scripts you may have.
29 # URI parsing algorithm was made more strict, so only prefixes which
30 looks like schemes will actually be schemes. Thanks
31 Michael Gusev <mgusev@sugarcrm.com> for fixing.
32 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
34 ! New directive %Core.AllowHostnameUnderscore which allows underscores
36 - Eliminate quadratic behavior in DOMLex by using a proper queue.
37 Thanks Ole Laursen for noticing this.
38 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
39 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
40 Networks for sponsoring this work.
41 - Made Linkify URL parser a bit less permissive, so that non-breaking
42 spaces and commas are not included as part of URL. Thanks nAS for fixing.
43 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
44 David Hirtz for reporting.
45 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
48 4.5.0, released 2013-02-17
49 # Fix bug where stacked attribute transforms clobber each other;
50 this also means it's no longer possible to override attribute
51 transforms in later modules. No internal code was using this
52 but this may break some clients.
53 # We now use SHA-1 to identify cached definitions, instead of MD5.
54 ! Support display:inline-block
55 ! Support for more white-space CSS values.
56 ! Permit underscores in font families
57 ! Support for page-break-* CSS3 properties when proprietary properties
59 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
60 SGML excludes checking. If HTML Purifier is removing too much text
61 and you don't care about full standards compliance, try setting this to
63 - Use prepend for SPL autoloading on PHP 5.3 and later.
64 - Fix bug with nofollow transform when pre-existing rel exists.
65 - Fix bug where background:url() always gets lower-cased
66 (but not background-image:url())
67 - Fix bug with non lower-case color names in HTML
68 - Fix bug where data URI validation doesn't remove temporary files.
69 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
70 - Don't remove certain empty tags on RemoveEmpty.
72 4.4.0, released 2012-01-18
73 # Removed PEARSax3 handler.
74 # URI.Munge now munges URIs inside the same host that go from https
75 to http. Reported by Neike Taika-Tessaro.
76 # Core.EscapeNonASCIICharacters now always transforms entities to
77 entities, even if target encoding is UTF-8.
78 # Tighten up selector validation in ExtractStyleBlocks.
79 Non-syntactically valid selectors are now rejected, along with
80 some of the more obscure ones such as attribute selectors, the
81 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
82 ID and class selectors now work properly with the relevant
83 configuration attributes. Also, mute errors when parsing CSS
84 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
85 ! Added support for 'scope' attribute on tables.
86 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
87 ! Properly handle sub-lists directly nested inside of lists in
88 a standards compliant way, by moving them into the preceding <li>
89 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
90 limited allowed comments in untrusted situations.
91 ! Implement iframes, and allow them to be used in untrusted mode with
92 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
93 <brad.froehle@gmail.com> for submitting an initial version of the patch.
94 ! The Forms module now works properly for transitional doctypes.
95 ! Added support for internationalized domain names. You need the PEAR
96 Net_IDNA2 module to be in your path; if it is installed, ensure the
97 class can be loaded and then set %Core.EnableIDNA to true.
98 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
99 <yramirez-htmlpurifier@adicio.com> for reporting.
100 - Explicitly initialize anonModule variable to null.
101 - Do not duplicate nofollow if already present. Thanks 178
103 - Do not add nofollow if hostname matches our current host. Thanks 178
104 for reporting, and Neike Taika-Tessaro for helping diagnose.
105 - Do not unset parser variable; this fixes intermittent serialization
106 problems. Thanks Neike Taika-Tessaro for reporting, bill
107 <10010tiger@gmail.com> for diagnosing.
108 - Fix iconv truncation bug, where non-UTF-8 target encodings see
109 output truncated after around 8000 characters. Thanks Jörg Ludwig
110 <joerg.ludwig@iserv.eu> for reporting.
111 - Fix broken table content model for XHTML1.1 (and also earlier
112 versions, although the W3C validator doesn't catch those violations).
113 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
115 4.3.0, released 2011-03-27
116 # Fixed broken caching of customized raw definitions, but requires an
117 API change. The old API still works but will emit a warning,
118 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
119 for how to upgrade your code.
120 # Protect against Internet Explorer innerHTML behavior by specially
121 treating attributes with backticks but no angled brackets, quotes or
122 spaces. This constitutes a slight semantic change, which can be
123 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
125 # Protect against cssText/innerHTML by restricting allowed characters
126 used in fonts further than mandated by the specification and encoding
127 some extra special characters in URLs. Reported by Neike
128 Taika-Tessaro and Mario Heiderich.
129 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
130 ! More types of SPL autoloaders allowed on later versions of PHP.
131 ! Implementations for position, top, left, right, bottom, z-index
132 when %CSS.Trusted is on.
133 ! Add %Cache.SerializerPermissions option for custom serializer
134 directory/file permissions
135 ! Fix longstanding bug in Flash support for non-IE browsers, and
136 allow more wmode attributes.
137 ! Add %CSS.AllowedFonts to restrict permissible font names.
138 - Switch to an iterative traversal of the DOM, which prevents us
139 from running out of stack space for deeply nested documents.
140 Thanks Maxim Krizhanovsky for contributing a patch.
141 - Make removal of conditional IE comments ungreedy; thanks Bernd
143 - Escape CDATA before removing Internet Explorer comments.
144 - Fix removal of id attributes under certain conditions by ensuring
145 armor attributes are preserved when recreating tags.
146 - Check if schema.ser was corrupted.
147 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
148 This safety check is only done for HTMLPurifier.auto.php; if you
149 are using standalone or the specialized includes files, you're
150 expected to know what you're doing.
151 - Stop repeatedly writing the cache file after I'm done customizing a
152 raw definition. Reported by ajh.
153 - Switch to using require_once in the Bootstrap to work around bad
154 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
155 - Fix URI handling when hostname is missing but scheme is present.
156 Reported by Neike Taika-Tessaro.
157 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
159 - Fix harmless notice from indexing into empty string. Thanks Matthijs
160 Kooijman <matthijs@stdin.nl> for reporting.
161 - Don't autoclose no parent elements are able to support the element
162 that triggered the autoclose. In particular fixes strange behavior
163 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
164 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
166 4.2.0, released 2010-09-15
167 ! Added %Core.RemoveProcessingInstructions, which lets you remove
168 <? ... ?> statements.
169 ! Added %URI.DisableResources functionality; the directive originally
170 did nothing. Thanks David Rothstein for reporting.
171 ! Add documentation about configuration directive types.
172 ! Add %CSS.ForbiddenProperties configuration directive.
173 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
174 to utilize full-screen mode.
175 ! Add optional support for the <code>file</code> URI scheme, enable
176 by explicitly setting %URI.AllowedSchemes.
177 ! Add %Core.NormalizeNewlines options to allow turning off newline
179 - Fix improper handling of Internet Explorer conditional comments
180 by parser. Thanks zmonteca for reporting.
181 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
182 Thanks sidepodcast for the fix.
183 - Warn if an element is allowed, but an attribute it requires is
186 4.1.1, released 2010-05-31
187 - Fix undefined index warnings in maintenance scripts.
188 - Fix bug in DirectLex for parsing elements with a single attribute
190 - Rewrite CSS output logic for font-family and url(). Thanks Mario
191 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
192 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
193 - Emit an error for CollectErrors if a body is extracted
194 - Fix bug where in background-position for center keyword handling.
195 - Fix infinite loop when a wrapper element is inserted in a context
196 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
197 - Remove +x bit and shebang from index.php; only supported mode is to
198 explicitly call it with php.
199 - Make test script less chatty when log_errors is on.
201 4.1.0, released 2010-04-26
202 ! Support proprietary height attribute on table element
203 ! Support YouTube slideshows that contain /cp/ in their URL.
204 ! Support for data: URI scheme; not enabled by default, add it using
206 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
207 ! Support for Internet Explorer compatibility with %HTML.SafeObject
208 using %Output.FlashCompat.
209 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
210 - Always quote the insides of url(...) in CSS.
212 4.0.0, released 2009-07-07
213 # APIs for ConfigSchema subsystem have substantially changed. See
214 docs/dev-config-bcbreaks.txt for details; in essence, anything that
215 had both namespace and directive now have a single unified key.
216 # Some configuration directives were renamed, specifically:
217 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
218 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
219 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
220 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
221 As usual, the old directive names will still work, but will throw E_NOTICE
223 # The allowed values for class have been relaxed to allow all of CDATA for
224 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
225 %Attr.ClassUseCDATA to false.
226 # Instead of appending the content model to an old content model, a blank
227 element will replace the old content model. You can use #SUPER to get
228 the old content model.
229 ! More robust support for name="" and id=""
230 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
231 configuration, and have changes to that configuration be propagated
232 to all of its children.
233 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
234 the name attribute when set. Use with care. Thanks Ian Cook for
236 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
237 tags that contain non-breaking spaces as well other whitespace. You
238 can also modify which tags should have maintained with
239 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
240 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
241 classes users can use to a specified finite set of classes, and
242 %Attr.ForbiddenClasses, which is the logical inverse.
243 ! You can now maintain your own configuration schema directories by
244 creating a config-schema.php file or passing an extra argument. Check
245 docs/dev-config-schema.html for more details.
246 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
247 your configuration in a compact serial file, which you can unserialize
248 and use directly without having to go through the overhead of setup.
249 - Fix bug where URIDefinition would not get cleared if it's directives got
251 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
252 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
253 - Make %URI.Munge not apply to links that have the same host as your host.
254 - Prevent stray </body> tag from truncating output, if a second </body>
256 . Created script maintenance/rename-config.php for renaming a configuration
257 directive while maintaining its alias. This script does not change source code.
258 . Implement namespace locking for definition construction, to prevent
259 bugs where a directive is used for definition construction but is not
260 used to construct the cache hash.
262 3.3.0, released 2009-02-16
263 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
264 ! Implement generic property list classess
265 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
266 does not do the "right thing" with characters not supported in the output
268 - Spellcheck UTF-8: The Secret To Character Encoding
269 - Fix improper removal of the contents of elements with only whitespace. Thanks
270 Eric Wald for reporting.
271 - Fix broken test suite in versions of PHP without spl_autoload_register()
272 - Fix degenerate case with YouTube filter involving double hyphens.
273 Thanks Pierre Attar for reporting.
274 - Fix YouTube rendering problem on certain versions of Firefox.
275 - Fix CSSDefinition Printer problems with decorators
276 - Add text parameter to unit tests, forces text output
277 . Add verbose mode to command line test runner, use (--verbose)
278 . Turn on unit tests for UnitConverter
279 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
280 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
282 . Removed trailing whitespace from all text files, see
283 remote-trailing-whitespace.php maintenance script.
284 . Convert configuration to use property list backend.
286 3.2.0, released 2008-10-31
287 # Using %Core.CollectErrors forces line number/column tracking on, whereas
288 previously you could theoretically turn it off.
289 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
290 use handleEnd() instead.
291 ! %Output.AttrSort for when you need your attributes in alphabetical order to
292 deal with a bug in FCKEditor. Requested by frank farmer.
293 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
294 ! Proper support for name attribute. It is now allowed and equivalent to the id
295 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
296 is heavy (for all doctypes).
297 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
298 use on hand-written HTML.
299 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
300 the strategy to be used, standalone, on untrusted input.
301 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
302 processing of left angled brackets in smileys and other whatnot.
303 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
304 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
305 the --only-phpt parameter, although for backwards-compatibility the flag
307 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
308 Users who are not performing inbound filtering, this may seem a little
309 useless, but as a bonus, the test suite and handling of edge cases is also
311 ! Experimental implementation of forms for %HTML.Trusted
312 ! Track column numbers when maintain line numbers is on
313 ! Proprietary 'background' attribute on table-related elements converted into
314 corresponding CSS. Thanks Fusemail for sponsoring this feature!
315 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
317 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
318 time of operation varies slightly from notifyEnd() as *all* end tokens are
319 processed by the injector before they are subject to the well-formedness rules.
320 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
321 basename of image when not present.
322 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
323 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
324 the other involving an undefined $is_folder error.
325 - Throw error when %Core.Encoding is set to a spurious value. Previously,
326 this errored silently and returned false.
327 - Redirected stderr to stdout for flush error output.
328 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
330 - Do not re-munge URL if the output URL has the same host as the input URL.
332 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
333 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
334 - Fix bug with inline elements in blockquotes conflicting with strict doctype
335 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
336 - Fix bug where dots and double-dots in absolute URLs without hostname were
337 not collapsed by URIFilter_MakeAbsolute.
338 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
339 by reordering their addition.
340 - Will now throw exception on many error conditions during lexer creation; also
341 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
343 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
344 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
345 Reported by David Morton.
346 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
347 for more interesting filter-backtracking
348 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
349 index to reprocess tokens.
350 . StringHashParser now allows for multiline sections with "empty" content;
351 previously the section would remain undefined.
352 . Added --quick option to multitest.php, which tests only the most recent
353 release for each series.
354 . Added --distro option to multitest.php, which accepts either 'normal' or
355 'standalone'. This supercedes --exclude-normal and --exclude-standalone
357 3.1.1, released 2008-06-19
358 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
359 In order to enable this again, please set %URI.MungeResources to true.
360 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
361 and height/width HTML with %HTML.MaxImgLength.
362 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
363 for sponsoring this feature. Check out the corresponding documentation
364 for details. (Att Nightly testers: The API for this feature changed before
365 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
366 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
367 ! Implemented post URI filtering. Set member variable $post to true to set
369 ! Allow modules to define injectors via $info_injector. Injectors are
370 automatically disabled if injector's needed elements are not found.
371 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
372 Thanks Chris for sponsoring. If you've been using ad hoc code from the
373 forums, PLEASE use this instead.
374 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
375 embedded, tag name, attribute name, CSS property name). See %URI.Munge
376 for more details. Requested by Jochem Blok.
377 - Disable percent height/width attributes for img.
378 - AttrValidator operations are now atomic; updates to attributes are not
379 manifest in token until end of operations. This prevents naughty internal
380 code from directly modifying CurrentToken when they're not supposed to.
381 This semantics change was requested by frank farmer.
382 - Percent encoding checks enabled for URI query and fragment
383 - Fix stray backslashes in font-family; CSS Unicode character escapes are
384 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
386 - Improve parseCDATA algorithm to take into account newline normalization
387 - Account for browser confusion between Yen character and backslash in
388 Shift_JIS encoding. This fix generalizes to any other encoding which is not
389 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
390 - Fix missing configuration parameter in Generator calls. Thanks vs for the
392 - Improved adherence to Unicode by checking for non-character codepoints.
393 Thanks Geoffrey Sneddon for reporting. This may result in degraded
394 performance for extremely large inputs.
395 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
397 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
398 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
400 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
401 to __construct($min, $max). __construct(true) is equivalent to
403 . Added HTMLPurifier_AttrDef_Switch class
404 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
405 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
406 get this called with the configuration object. All modules now
407 use this rather than __construct(), although legacy code using constructors
408 will still work--the new format, however, lets modules access the
409 configuration object for HTML namespace dependant tweaks.
410 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
411 . ConfigSchema data-structure heavily optimized; on average it uses a third
412 the memory it did previously. The interface has changed accordingly,
413 consult changes to HTMLPurifier_Config for details.
414 . Variable parsing types now are magic integers instead of strings
415 . Added benchmark for ConfigSchema
416 . HTMLPurifier_Generator requires $config and $context parameters. If you
417 don't know what they should be, use HTMLPurifier_Config::createDefault()
418 and new HTMLPurifier_Context().
419 . Printers now properly distinguish between output configuration, and
420 target configuration. This is not applicable to scripts using
421 the Printers for HTML Purifier related tasks.
422 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
423 fatal errors will ensue.
424 . URIFilter->prepare can return false in order to abort loading of the filter
425 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
426 an external resource.
427 . %URI.Munge functionality factored out into a post-filter class.
428 . Added CurrentCSSProperty context variable during CSS validation
430 3.1.0, released 2008-05-18
431 # Unnecessary references to objects (vestiges of PHP4) removed from method
432 signatures. The following methods do not need references when assigning from
433 them and will result in E_STRICT errors if you try:
434 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
435 + HTMLPurifier_ConfigSchema::instance()
436 + HTMLPurifier_DefinitionCacheFactory::instance()
437 + HTMLPurifier_DefinitionCacheFactory->create()
438 + HTMLPurifier_DoctypeRegistry->register()
439 + HTMLPurifier_DoctypeRegistry->get()
440 + HTMLPurifier_HTMLModule->addElement()
441 + HTMLPurifier_HTMLModule->addBlankElement()
442 + HTMLPurifier_LanguageFactory::instance()
443 # Printer_ConfigForm's get*() functions were static-ified
444 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
445 form of tag@attr, NOT tag.attr (which will throw an error and won't do
446 anything). This is for forwards compatibility with XML; you'd do best
447 to migrate an %HTML.AllowedAttributes directives to this syntax too.
448 ! Allow index to be false for config from form creation
449 ! Added HTMLPurifier::VERSION constant
450 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
451 and allows for version numbers like "3.1.0-dev".
452 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
453 ! HTML Purifier's URI handling is a lot more robust, with much stricter
454 validation checks and better percent encoding handling. Thanks Gareth Heyes
455 for indicating security vulnerabilities from lax percent encoding.
456 ! Bootstrap autoloader deals more robustly with classes that don't exist,
457 preventing class_exists($class, true) from barfing.
458 - InterchangeBuilder now alphabetizes its lists
459 - Validation error in configdoc output fixed
460 - Iconv and other encoding errors muted even with custom error handlers that
461 do not honor error_reporting
462 - Add protection against imagecrash attack with CSS height/width
463 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
464 - Fixed and revamped broken ConfigForm smoketest
465 - Bug with bool/null fields in Printer_ConfigForm fixed
466 - Bug with global forbidden attributes fixed
467 - Improved error messages for allowed and forbidden HTML elements and attributes
468 - Missing (or null) in configdoc documentation restored
469 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
470 of DOM), HTML Purifier punts to DirectLex
471 - Fatal error with unserialization of ScriptRequired
472 - Created directories are now chmod'ed properly
473 - Fixed bug with fallback languages in LanguageFactory
474 - Standalone testing setup properly with autoload
475 . Out-of-date documentation revised
476 . UTF-8 encoding check optimization as suggested by Diego
477 . HTMLPurifier_Error removed in favor of exceptions

485 3.1.0rc1, released 2008-04-22
486 # Autoload support added. Internal require_once's removed in favor of an
487 explicit require list or autoloading. To use HTML Purifier,
488 you must now either use HTMLPurifier.auto.php
489 or HTMLPurifier.includes.php; setting the include path and including
490 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
491 as well to register our autoload handler (or modify your autoload function
492 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
493 HTMLPurifier.safe-includes.php for a less performance friendly but more
494 user-friendly library load.
495 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
496 information is stored in the ConfigSchema directory, and the
497 maintenance/generate-schema-cache.php generates the schema.ser file, which
498 is now instantiated. Support for userland schema changes coming soon!
499 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
500 alias; to get rid of these errors just modify your configuration to use
501 the new directive name.
502 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
503 enabled using %Filter.$filter_name or by setting your own filters using
505 # Directive-level safety properties superceded in favor of module-level
506 safety. Internal method HTMLModule->addElement() has changed, although
507 the externally visible HTMLDefinition->addElement has *not* changed.
508 ! Extra utility classes for testing and non-library operations can
509 be found in extras/. Specifically, these are FSTools and ConfigDoc.

634 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
635 to better communicate its purpose

662 slashes inside attribute values.
663 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly

746 linkify your HTML input by setting %AutoFormat.AutoParagraph and
747 %AutoFormat.Linkify to true
748 ! Newlines normalized internally, and then converted back to the
749 value of PHP_EOL. If this is not desired, set your newline format
750 using %Output.Newline.
751 ! Beta error collection, messages are implemented for the most generic
752 cases involving Lexing or Strategies

795 # New compact syntax for AttrDef objects that can be used to instantiate
796 new objects via make()
797 # Definitions (esp. HTMLDefinition) are now cached for a significant
798 performance boost. You can disable caching by setting %Core.DefinitionCache
