4 = KEY ====================
10 ==========================
12 4.7.0, released 2015-08-04
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'
25 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
28 4.6.0, released 2013-11-30
29 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
30 Please update any verification scripts you may have.
31 # URI parsing algorithm was made more strict, so only prefixes which
32 looks like schemes will actually be schemes. Thanks
33 Michael Gusev <mgusev@sugarcrm.com> for fixing.
34 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
36 ! New directive %Core.AllowHostnameUnderscore which allows underscores
38 - Eliminate quadratic behavior in DOMLex by using a proper queue.
39 Thanks Ole Laursen for noticing this.
40 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
41 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
42 Networks for sponsoring this work.
43 - Made Linkify URL parser a bit less permissive, so that non-breaking
44 spaces and commas are not included as part of URL. Thanks nAS for fixing.
45 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
46 David Hirtz for reporting.
47 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
50 4.5.0, released 2013-02-17
51 # Fix bug where stacked attribute transforms clobber each other;
52 this also means it's no longer possible to override attribute
53 transforms in later modules. No internal code was using this
54 but this may break some clients.
55 # We now use SHA-1 to identify cached definitions, instead of MD5.
56 ! Support display:inline-block
57 ! Support for more white-space CSS values.
58 ! Permit underscores in font families
59 ! Support for page-break-* CSS3 properties when proprietary properties
61 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
62 SGML excludes checking. If HTML Purifier is removing too much text
63 and you don't care about full standards compliance, try setting this to
65 - Use prepend for SPL autoloading on PHP 5.3 and later.
66 - Fix bug with nofollow transform when pre-existing rel exists.
67 - Fix bug where background:url() always gets lower-cased
68 (but not background-image:url())
69 - Fix bug with non lower-case color names in HTML
70 - Fix bug where data URI validation doesn't remove temporary files.
71 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
72 - Don't remove certain empty tags on RemoveEmpty.
74 4.4.0, released 2012-01-18
75 # Removed PEARSax3 handler.
76 # URI.Munge now munges URIs inside the same host that go from https
77 to http. Reported by Neike Taika-Tessaro.
78 # Core.EscapeNonASCIICharacters now always transforms entities to
79 entities, even if target encoding is UTF-8.
80 # Tighten up selector validation in ExtractStyleBlocks.
81 Non-syntactically valid selectors are now rejected, along with
82 some of the more obscure ones such as attribute selectors, the
83 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
84 ID and class selectors now work properly with the relevant
85 configuration attributes. Also, mute errors when parsing CSS
86 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
87 ! Added support for 'scope' attribute on tables.
88 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
89 ! Properly handle sub-lists directly nested inside of lists in
90 a standards compliant way, by moving them into the preceding <li>
91 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
92 limited allowed comments in untrusted situations.
93 ! Implement iframes, and allow them to be used in untrusted mode with
94 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
95 <brad.froehle@gmail.com> for submitting an initial version of the patch.
96 ! The Forms module now works properly for transitional doctypes.
97 ! Added support for internationalized domain names. You need the PEAR
98 Net_IDNA2 module to be in your path; if it is installed, ensure the
99 class can be loaded and then set %Core.EnableIDNA to true.
100 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
101 <yramirez-htmlpurifier@adicio.com> for reporting.
102 - Explicitly initialize anonModule variable to null.
103 - Do not duplicate nofollow if already present. Thanks 178
105 - Do not add nofollow if hostname matches our current host. Thanks 178
106 for reporting, and Neike Taika-Tessaro for helping diagnose.
107 - Do not unset parser variable; this fixes intermittent serialization
108 problems. Thanks Neike Taika-Tessaro for reporting, bill
109 <10010tiger@gmail.com> for diagnosing.
110 - Fix iconv truncation bug, where non-UTF-8 target encodings see
111 output truncated after around 8000 characters. Thanks Jörg Ludwig
112 <joerg.ludwig@iserv.eu> for reporting.
113 - Fix broken table content model for XHTML1.1 (and also earlier
114 versions, although the W3C validator doesn't catch those violations).
115 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
117 4.3.0, released 2011-03-27
118 # Fixed broken caching of customized raw definitions, but requires an
119 API change. The old API still works but will emit a warning,
120 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
121 for how to upgrade your code.
122 # Protect against Internet Explorer innerHTML behavior by specially
123 treating attributes with backticks but no angled brackets, quotes or
124 spaces. This constitutes a slight semantic change, which can be
125 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
127 # Protect against cssText/innerHTML by restricting allowed characters
128 used in fonts further than mandated by the specification and encoding
129 some extra special characters in URLs. Reported by Neike
130 Taika-Tessaro and Mario Heiderich.
131 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
132 ! More types of SPL autoloaders allowed on later versions of PHP.
133 ! Implementations for position, top, left, right, bottom, z-index
134 when %CSS.Trusted is on.
135 ! Add %Cache.SerializerPermissions option for custom serializer
136 directory/file permissions
137 ! Fix longstanding bug in Flash support for non-IE browsers, and
138 allow more wmode attributes.
139 ! Add %CSS.AllowedFonts to restrict permissible font names.
140 - Switch to an iterative traversal of the DOM, which prevents us
141 from running out of stack space for deeply nested documents.
142 Thanks Maxim Krizhanovsky for contributing a patch.
143 - Make removal of conditional IE comments ungreedy; thanks Bernd
145 - Escape CDATA before removing Internet Explorer comments.
146 - Fix removal of id attributes under certain conditions by ensuring
147 armor attributes are preserved when recreating tags.
148 - Check if schema.ser was corrupted.
149 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
150 This safety check is only done for HTMLPurifier.auto.php; if you
151 are using standalone or the specialized includes files, you're
152 expected to know what you're doing.
153 - Stop repeatedly writing the cache file after I'm done customizing a
154 raw definition. Reported by ajh.
155 - Switch to using require_once in the Bootstrap to work around bad
156 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
157 - Fix URI handling when hostname is missing but scheme is present.
158 Reported by Neike Taika-Tessaro.
159 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
161 - Fix harmless notice from indexing into empty string. Thanks Matthijs
162 Kooijman <matthijs@stdin.nl> for reporting.
163 - Don't autoclose no parent elements are able to support the element
164 that triggered the autoclose. In particular fixes strange behavior
165 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
166 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
168 4.2.0, released 2010-09-15
169 ! Added %Core.RemoveProcessingInstructions, which lets you remove
170 <? ... ?> statements.
171 ! Added %URI.DisableResources functionality; the directive originally
172 did nothing. Thanks David Rothstein for reporting.
173 ! Add documentation about configuration directive types.
174 ! Add %CSS.ForbiddenProperties configuration directive.
175 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
176 to utilize full-screen mode.
177 ! Add optional support for the <code>file</code> URI scheme, enable
178 by explicitly setting %URI.AllowedSchemes.
179 ! Add %Core.NormalizeNewlines options to allow turning off newline
181 - Fix improper handling of Internet Explorer conditional comments
182 by parser. Thanks zmonteca for reporting.
183 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
184 Thanks sidepodcast for the fix.
185 - Warn if an element is allowed, but an attribute it requires is
188 4.1.1, released 2010-05-31
189 - Fix undefined index warnings in maintenance scripts.
190 - Fix bug in DirectLex for parsing elements with a single attribute
192 - Rewrite CSS output logic for font-family and url(). Thanks Mario
193 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
194 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
195 - Emit an error for CollectErrors if a body is extracted
196 - Fix bug where in background-position for center keyword handling.
197 - Fix infinite loop when a wrapper element is inserted in a context
198 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
199 - Remove +x bit and shebang from index.php; only supported mode is to
200 explicitly call it with php.
201 - Make test script less chatty when log_errors is on.
203 4.1.0, released 2010-04-26
204 ! Support proprietary height attribute on table element
205 ! Support YouTube slideshows that contain /cp/ in their URL.
206 ! Support for data: URI scheme; not enabled by default, add it using
208 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
209 ! Support for Internet Explorer compatibility with %HTML.SafeObject
210 using %Output.FlashCompat.
211 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
212 - Always quote the insides of url(...) in CSS.
214 4.0.0, released 2009-07-07
215 # APIs for ConfigSchema subsystem have substantially changed. See
216 docs/dev-config-bcbreaks.txt for details; in essence, anything that
217 had both namespace and directive now have a single unified key.
218 # Some configuration directives were renamed, specifically:
219 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
220 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
221 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
222 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
223 As usual, the old directive names will still work, but will throw E_NOTICE
225 # The allowed values for class have been relaxed to allow all of CDATA for
226 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
227 %Attr.ClassUseCDATA to false.
228 # Instead of appending the content model to an old content model, a blank
229 element will replace the old content model. You can use #SUPER to get
230 the old content model.
231 ! More robust support for name="" and id=""
232 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
233 configuration, and have changes to that configuration be propagated
234 to all of its children.
235 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
236 the name attribute when set. Use with care. Thanks Ian Cook for
238 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
239 tags that contain non-breaking spaces as well other whitespace. You
240 can also modify which tags should have maintained with
241 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
242 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
243 classes users can use to a specified finite set of classes, and
244 %Attr.ForbiddenClasses, which is the logical inverse.
245 ! You can now maintain your own configuration schema directories by
246 creating a config-schema.php file or passing an extra argument. Check
247 docs/dev-config-schema.html for more details.
248 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
249 your configuration in a compact serial file, which you can unserialize
250 and use directly without having to go through the overhead of setup.
251 - Fix bug where URIDefinition would not get cleared if it's directives got
253 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
254 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
255 - Make %URI.Munge not apply to links that have the same host as your host.
256 - Prevent stray </body> tag from truncating output, if a second </body>
258 . Created script maintenance/rename-config.php for renaming a configuration
259 directive while maintaining its alias. This script does not change source code.
260 . Implement namespace locking for definition construction, to prevent
261 bugs where a directive is used for definition construction but is not
262 used to construct the cache hash.
264 3.3.0, released 2009-02-16
265 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
266 ! Implement generic property list classess
267 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
268 does not do the "right thing" with characters not supported in the output
270 - Spellcheck UTF-8: The Secret To Character Encoding
271 - Fix improper removal of the contents of elements with only whitespace. Thanks
272 Eric Wald for reporting.
273 - Fix broken test suite in versions of PHP without spl_autoload_register()
274 - Fix degenerate case with YouTube filter involving double hyphens.
275 Thanks Pierre Attar for reporting.
276 - Fix YouTube rendering problem on certain versions of Firefox.
277 - Fix CSSDefinition Printer problems with decorators
278 - Add text parameter to unit tests, forces text output
279 . Add verbose mode to command line test runner, use (--verbose)
280 . Turn on unit tests for UnitConverter
281 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
282 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
284 . Removed trailing whitespace from all text files, see
285 remote-trailing-whitespace.php maintenance script.
286 . Convert configuration to use property list backend.
288 3.2.0, released 2008-10-31
289 # Using %Core.CollectErrors forces line number/column tracking on, whereas
290 previously you could theoretically turn it off.
291 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
292 use handleEnd() instead.
293 ! %Output.AttrSort for when you need your attributes in alphabetical order to
294 deal with a bug in FCKEditor. Requested by frank farmer.
295 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
296 ! Proper support for name attribute. It is now allowed and equivalent to the id
297 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
298 is heavy (for all doctypes).
299 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
300 use on hand-written HTML.
301 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
302 the strategy to be used, standalone, on untrusted input.
303 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
304 processing of left angled brackets in smileys and other whatnot.
305 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
306 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
307 the --only-phpt parameter, although for backwards-compatibility the flag
309 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
310 Users who are not performing inbound filtering, this may seem a little
311 useless, but as a bonus, the test suite and handling of edge cases is also
313 ! Experimental implementation of forms for %HTML.Trusted
314 ! Track column numbers when maintain line numbers is on
315 ! Proprietary 'background' attribute on table-related elements converted into
316 corresponding CSS. Thanks Fusemail for sponsoring this feature!
317 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
319 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
320 time of operation varies slightly from notifyEnd() as *all* end tokens are
321 processed by the injector before they are subject to the well-formedness rules.
322 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
323 basename of image when not present.
324 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
325 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
326 the other involving an undefined $is_folder error.
327 - Throw error when %Core.Encoding is set to a spurious value. Previously,
328 this errored silently and returned false.
329 - Redirected stderr to stdout for flush error output.
330 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
332 - Do not re-munge URL if the output URL has the same host as the input URL.
334 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
335 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
336 - Fix bug with inline elements in blockquotes conflicting with strict doctype
337 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
338 - Fix bug where dots and double-dots in absolute URLs without hostname were
339 not collapsed by URIFilter_MakeAbsolute.
340 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
341 by reordering their addition.
342 - Will now throw exception on many error conditions during lexer creation; also
343 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
345 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
346 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
347 Reported by David Morton.
348 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
349 for more interesting filter-backtracking
350 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
351 index to reprocess tokens.
352 . StringHashParser now allows for multiline sections with "empty" content;
353 previously the section would remain undefined.
354 . Added --quick option to multitest.php, which tests only the most recent
355 release for each series.
356 . Added --distro option to multitest.php, which accepts either 'normal' or
357 'standalone'. This supercedes --exclude-normal and --exclude-standalone
359 3.1.1, released 2008-06-19
360 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
361 In order to enable this again, please set %URI.MungeResources to true.
362 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
363 and height/width HTML with %HTML.MaxImgLength.
364 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
365 for sponsoring this feature. Check out the corresponding documentation
366 for details. (Att Nightly testers: The API for this feature changed before
367 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
368 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
369 ! Implemented post URI filtering. Set member variable $post to true to set
371 ! Allow modules to define injectors via $info_injector. Injectors are
372 automatically disabled if injector's needed elements are not found.
373 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
374 Thanks Chris for sponsoring. If you've been using ad hoc code from the
375 forums, PLEASE use this instead.
376 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
377 embedded, tag name, attribute name, CSS property name). See %URI.Munge
378 for more details. Requested by Jochem Blok.
379 - Disable percent height/width attributes for img.
380 - AttrValidator operations are now atomic; updates to attributes are not
381 manifest in token until end of operations. This prevents naughty internal
382 code from directly modifying CurrentToken when they're not supposed to.
383 This semantics change was requested by frank farmer.
384 - Percent encoding checks enabled for URI query and fragment
385 - Fix stray backslashes in font-family; CSS Unicode character escapes are
386 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
388 - Improve parseCDATA algorithm to take into account newline normalization
389 - Account for browser confusion between Yen character and backslash in
390 Shift_JIS encoding. This fix generalizes to any other encoding which is not
391 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
392 - Fix missing configuration parameter in Generator calls. Thanks vs for the
394 - Improved adherence to Unicode by checking for non-character codepoints.
395 Thanks Geoffrey Sneddon for reporting. This may result in degraded
396 performance for extremely large inputs.
397 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
399 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
400 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
402 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
403 to __construct($min, $max). __construct(true) is equivalent to
405 . Added HTMLPurifier_AttrDef_Switch class
406 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
407 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
408 get this called with the configuration object. All modules now
409 use this rather than __construct(), although legacy code using constructors
410 will still work--the new format, however, lets modules access the
411 configuration object for HTML namespace dependant tweaks.
412 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
413 . ConfigSchema data-structure heavily optimized; on average it uses a third
414 the memory it did previously. The interface has changed accordingly,
415 consult changes to HTMLPurifier_Config for details.
416 . Variable parsing types now are magic integers instead of strings
417 . Added benchmark for ConfigSchema
418 . HTMLPurifier_Generator requires $config and $context parameters. If you
419 don't know what they should be, use HTMLPurifier_Config::createDefault()
420 and new HTMLPurifier_Context().
421 . Printers now properly distinguish between output configuration, and
422 target configuration. This is not applicable to scripts using
423 the Printers for HTML Purifier related tasks.
424 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
425 fatal errors will ensue.
426 . URIFilter->prepare can return false in order to abort loading of the filter
427 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
428 an external resource.
429 . %URI.Munge functionality factored out into a post-filter class.
430 . Added CurrentCSSProperty context variable during CSS validation
432 3.1.0, released 2008-05-18
433 # Unnecessary references to objects (vestiges of PHP4) removed from method
434 signatures. The following methods do not need references when assigning from
435 them and will result in E_STRICT errors if you try:
436 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
437 + HTMLPurifier_ConfigSchema::instance()
438 + HTMLPurifier_DefinitionCacheFactory::instance()
439 + HTMLPurifier_DefinitionCacheFactory->create()
440 + HTMLPurifier_DoctypeRegistry->register()
441 + HTMLPurifier_DoctypeRegistry->get()
442 + HTMLPurifier_HTMLModule->addElement()
443 + HTMLPurifier_HTMLModule->addBlankElement()
444 + HTMLPurifier_LanguageFactory::instance()
445 # Printer_ConfigForm's get*() functions were static-ified
446 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
447 form of tag@attr, NOT tag.attr (which will throw an error and won't do
448 anything). This is for forwards compatibility with XML; you'd do best
449 to migrate an %HTML.AllowedAttributes directives to this syntax too.
450 ! Allow index to be false for config from form creation
451 ! Added HTMLPurifier::VERSION constant
452 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
453 and allows for version numbers like "3.1.0-dev".
454 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
455 ! HTML Purifier's URI handling is a lot more robust, with much stricter
456 validation checks and better percent encoding handling. Thanks Gareth Heyes
457 for indicating security vulnerabilities from lax percent encoding.
458 ! Bootstrap autoloader deals more robustly with classes that don't exist,
459 preventing class_exists($class, true) from barfing.
460 - InterchangeBuilder now alphabetizes its lists
461 - Validation error in configdoc output fixed
462 - Iconv and other encoding errors muted even with custom error handlers that
463 do not honor error_reporting
464 - Add protection against imagecrash attack with CSS height/width
465 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
466 - Fixed and revamped broken ConfigForm smoketest
467 - Bug with bool/null fields in Printer_ConfigForm fixed
468 - Bug with global forbidden attributes fixed
469 - Improved error messages for allowed and forbidden HTML elements and attributes
470 - Missing (or null) in configdoc documentation restored
471 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
472 of DOM), HTML Purifier punts to DirectLex
473 - Fatal error with unserialization of ScriptRequired
474 - Created directories are now chmod'ed properly
475 - Fixed bug with fallback languages in LanguageFactory
476 - Standalone testing setup properly with autoload

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

636 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
637 to better communicate its purpose

661 namespace. Also, this is PHP5 only.
662 ! CSS property border-spacing implemented
663 - Fix non-visible parsing error in DirectLex with empty tags that have
664 slashes inside attribute values.
665 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
666 accepted as valid CSS. Usually non-visible, because this styling is the
667 default for tables in most browsers. Thanks Brett Zamir for pointing
669 - Fix validation errors in configuration form
670 - Hammer out a bunch of edge-case bugs in the standalone distribution

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

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

748 linkify your HTML input by setting %AutoFormat.AutoParagraph and
749 %AutoFormat.Linkify to true
750 ! Newlines normalized internally, and then converted back to the
751 value of PHP_EOL. If this is not desired, set your newline format
752 using %Output.Newline.
753 ! Beta error collection, messages are implemented for the most generic
754 cases involving Lexing or Strategies
755 - Clean up special case code for <script> tags

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