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.
24 4.6.0, released 2013-11-30
25 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
26 Please update any verification scripts you may have.
27 # URI parsing algorithm was made more strict, so only prefixes which
28 looks like schemes will actually be schemes. Thanks
29 Michael Gusev <mgusev@sugarcrm.com> for fixing.
30 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
32 ! New directive %Core.AllowHostnameUnderscore which allows underscores
34 - Eliminate quadratic behavior in DOMLex by using a proper queue.
35 Thanks Ole Laursen for noticing this.
36 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
37 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
38 Networks for sponsoring this work.
39 - Made Linkify URL parser a bit less permissive, so that non-breaking
40 spaces and commas are not included as part of URL. Thanks nAS for fixing.
41 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
42 David Hirtz for reporting.
43 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
46 4.5.0, released 2013-02-17
47 # Fix bug where stacked attribute transforms clobber each other;
48 this also means it's no longer possible to override attribute
49 transforms in later modules. No internal code was using this
50 but this may break some clients.
51 # We now use SHA-1 to identify cached definitions, instead of MD5.
52 ! Support display:inline-block
53 ! Support for more white-space CSS values.
54 ! Permit underscores in font families
55 ! Support for page-break-* CSS3 properties when proprietary properties
57 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
58 SGML excludes checking. If HTML Purifier is removing too much text
59 and you don't care about full standards compliance, try setting this to
61 - Use prepend for SPL autoloading on PHP 5.3 and later.
62 - Fix bug with nofollow transform when pre-existing rel exists.
63 - Fix bug where background:url() always gets lower-cased
64 (but not background-image:url())
65 - Fix bug with non lower-case color names in HTML
66 - Fix bug where data URI validation doesn't remove temporary files.
67 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
68 - Don't remove certain empty tags on RemoveEmpty.
70 4.4.0, released 2012-01-18
71 # Removed PEARSax3 handler.
72 # URI.Munge now munges URIs inside the same host that go from https
73 to http. Reported by Neike Taika-Tessaro.
74 # Core.EscapeNonASCIICharacters now always transforms entities to
75 entities, even if target encoding is UTF-8.
76 # Tighten up selector validation in ExtractStyleBlocks.
77 Non-syntactically valid selectors are now rejected, along with
78 some of the more obscure ones such as attribute selectors, the
79 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
80 ID and class selectors now work properly with the relevant
81 configuration attributes. Also, mute errors when parsing CSS
82 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
83 ! Added support for 'scope' attribute on tables.
84 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
85 ! Properly handle sub-lists directly nested inside of lists in
86 a standards compliant way, by moving them into the preceding <li>
87 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
88 limited allowed comments in untrusted situations.
89 ! Implement iframes, and allow them to be used in untrusted mode with
90 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
91 <brad.froehle@gmail.com> for submitting an initial version of the patch.
92 ! The Forms module now works properly for transitional doctypes.
93 ! Added support for internationalized domain names. You need the PEAR
94 Net_IDNA2 module to be in your path; if it is installed, ensure the
95 class can be loaded and then set %Core.EnableIDNA to true.
96 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
97 <yramirez-htmlpurifier@adicio.com> for reporting.
98 - Explicitly initialize anonModule variable to null.
99 - Do not duplicate nofollow if already present. Thanks 178
101 - Do not add nofollow if hostname matches our current host. Thanks 178
102 for reporting, and Neike Taika-Tessaro for helping diagnose.
103 - Do not unset parser variable; this fixes intermittent serialization
104 problems. Thanks Neike Taika-Tessaro for reporting, bill
105 <10010tiger@gmail.com> for diagnosing.
106 - Fix iconv truncation bug, where non-UTF-8 target encodings see
107 output truncated after around 8000 characters. Thanks Jörg Ludwig
108 <joerg.ludwig@iserv.eu> for reporting.
109 - Fix broken table content model for XHTML1.1 (and also earlier
110 versions, although the W3C validator doesn't catch those violations).
111 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
113 4.3.0, released 2011-03-27
114 # Fixed broken caching of customized raw definitions, but requires an
115 API change. The old API still works but will emit a warning,
116 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
117 for how to upgrade your code.
118 # Protect against Internet Explorer innerHTML behavior by specially
119 treating attributes with backticks but no angled brackets, quotes or
120 spaces. This constitutes a slight semantic change, which can be
121 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
123 # Protect against cssText/innerHTML by restricting allowed characters
124 used in fonts further than mandated by the specification and encoding
125 some extra special characters in URLs. Reported by Neike
126 Taika-Tessaro and Mario Heiderich.
127 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
128 ! More types of SPL autoloaders allowed on later versions of PHP.
129 ! Implementations for position, top, left, right, bottom, z-index
130 when %CSS.Trusted is on.
131 ! Add %Cache.SerializerPermissions option for custom serializer
132 directory/file permissions
133 ! Fix longstanding bug in Flash support for non-IE browsers, and
134 allow more wmode attributes.
135 ! Add %CSS.AllowedFonts to restrict permissible font names.
136 - Switch to an iterative traversal of the DOM, which prevents us
137 from running out of stack space for deeply nested documents.
138 Thanks Maxim Krizhanovsky for contributing a patch.
139 - Make removal of conditional IE comments ungreedy; thanks Bernd
141 - Escape CDATA before removing Internet Explorer comments.
142 - Fix removal of id attributes under certain conditions by ensuring
143 armor attributes are preserved when recreating tags.
144 - Check if schema.ser was corrupted.
145 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
146 This safety check is only done for HTMLPurifier.auto.php; if you
147 are using standalone or the specialized includes files, you're
148 expected to know what you're doing.
149 - Stop repeatedly writing the cache file after I'm done customizing a
150 raw definition. Reported by ajh.
151 - Switch to using require_once in the Bootstrap to work around bad
152 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
153 - Fix URI handling when hostname is missing but scheme is present.
154 Reported by Neike Taika-Tessaro.
155 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
157 - Fix harmless notice from indexing into empty string. Thanks Matthijs
158 Kooijman <matthijs@stdin.nl> for reporting.
159 - Don't autoclose no parent elements are able to support the element
160 that triggered the autoclose. In particular fixes strange behavior
161 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
162 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
164 4.2.0, released 2010-09-15
165 ! Added %Core.RemoveProcessingInstructions, which lets you remove
166 <? ... ?> statements.
167 ! Added %URI.DisableResources functionality; the directive originally
168 did nothing. Thanks David Rothstein for reporting.
169 ! Add documentation about configuration directive types.
170 ! Add %CSS.ForbiddenProperties configuration directive.
171 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
172 to utilize full-screen mode.
173 ! Add optional support for the <code>file</code> URI scheme, enable
174 by explicitly setting %URI.AllowedSchemes.
175 ! Add %Core.NormalizeNewlines options to allow turning off newline
177 - Fix improper handling of Internet Explorer conditional comments
178 by parser. Thanks zmonteca for reporting.
179 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
180 Thanks sidepodcast for the fix.
181 - Warn if an element is allowed, but an attribute it requires is
184 4.1.1, released 2010-05-31
185 - Fix undefined index warnings in maintenance scripts.
186 - Fix bug in DirectLex for parsing elements with a single attribute
188 - Rewrite CSS output logic for font-family and url(). Thanks Mario
189 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
190 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
191 - Emit an error for CollectErrors if a body is extracted
192 - Fix bug where in background-position for center keyword handling.
193 - Fix infinite loop when a wrapper element is inserted in a context
194 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
195 - Remove +x bit and shebang from index.php; only supported mode is to
196 explicitly call it with php.
197 - Make test script less chatty when log_errors is on.
199 4.1.0, released 2010-04-26
200 ! Support proprietary height attribute on table element
201 ! Support YouTube slideshows that contain /cp/ in their URL.
202 ! Support for data: URI scheme; not enabled by default, add it using
204 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
205 ! Support for Internet Explorer compatibility with %HTML.SafeObject
206 using %Output.FlashCompat.
207 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
208 - Always quote the insides of url(...) in CSS.
210 4.0.0, released 2009-07-07
211 # APIs for ConfigSchema subsystem have substantially changed. See
212 docs/dev-config-bcbreaks.txt for details; in essence, anything that
213 had both namespace and directive now have a single unified key.
214 # Some configuration directives were renamed, specifically:
215 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
216 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
217 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
218 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
219 As usual, the old directive names will still work, but will throw E_NOTICE
221 # The allowed values for class have been relaxed to allow all of CDATA for
222 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
223 %Attr.ClassUseCDATA to false.
224 # Instead of appending the content model to an old content model, a blank
225 element will replace the old content model. You can use #SUPER to get
226 the old content model.
227 ! More robust support for name="" and id=""
228 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
229 configuration, and have changes to that configuration be propagated
230 to all of its children.
231 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
232 the name attribute when set. Use with care. Thanks Ian Cook for
234 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
235 tags that contain non-breaking spaces as well other whitespace. You
236 can also modify which tags should have maintained with
237 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
238 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
239 classes users can use to a specified finite set of classes, and
240 %Attr.ForbiddenClasses, which is the logical inverse.
241 ! You can now maintain your own configuration schema directories by
242 creating a config-schema.php file or passing an extra argument. Check
243 docs/dev-config-schema.html for more details.
244 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
245 your configuration in a compact serial file, which you can unserialize
246 and use directly without having to go through the overhead of setup.
247 - Fix bug where URIDefinition would not get cleared if it's directives got
249 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
250 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
251 - Make %URI.Munge not apply to links that have the same host as your host.
252 - Prevent stray </body> tag from truncating output, if a second </body>
254 . Created script maintenance/rename-config.php for renaming a configuration
255 directive while maintaining its alias. This script does not change source code.
256 . Implement namespace locking for definition construction, to prevent
257 bugs where a directive is used for definition construction but is not
258 used to construct the cache hash.
260 3.3.0, released 2009-02-16
261 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
262 ! Implement generic property list classess
263 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
264 does not do the "right thing" with characters not supported in the output
266 - Spellcheck UTF-8: The Secret To Character Encoding
267 - Fix improper removal of the contents of elements with only whitespace. Thanks
268 Eric Wald for reporting.
269 - Fix broken test suite in versions of PHP without spl_autoload_register()
270 - Fix degenerate case with YouTube filter involving double hyphens.
271 Thanks Pierre Attar for reporting.
272 - Fix YouTube rendering problem on certain versions of Firefox.
273 - Fix CSSDefinition Printer problems with decorators
274 - Add text parameter to unit tests, forces text output
275 . Add verbose mode to command line test runner, use (--verbose)
276 . Turn on unit tests for UnitConverter
277 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
278 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
280 . Removed trailing whitespace from all text files, see
281 remote-trailing-whitespace.php maintenance script.
282 . Convert configuration to use property list backend.
284 3.2.0, released 2008-10-31
285 # Using %Core.CollectErrors forces line number/column tracking on, whereas
286 previously you could theoretically turn it off.
287 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
288 use handleEnd() instead.
289 ! %Output.AttrSort for when you need your attributes in alphabetical order to
290 deal with a bug in FCKEditor. Requested by frank farmer.
291 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
292 ! Proper support for name attribute. It is now allowed and equivalent to the id
293 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
294 is heavy (for all doctypes).
295 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
296 use on hand-written HTML.
297 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
298 the strategy to be used, standalone, on untrusted input.
299 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
300 processing of left angled brackets in smileys and other whatnot.
301 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
302 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
303 the --only-phpt parameter, although for backwards-compatibility the flag
305 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
306 Users who are not performing inbound filtering, this may seem a little
307 useless, but as a bonus, the test suite and handling of edge cases is also
309 ! Experimental implementation of forms for %HTML.Trusted
310 ! Track column numbers when maintain line numbers is on
311 ! Proprietary 'background' attribute on table-related elements converted into
312 corresponding CSS. Thanks Fusemail for sponsoring this feature!
313 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
315 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
316 time of operation varies slightly from notifyEnd() as *all* end tokens are
317 processed by the injector before they are subject to the well-formedness rules.
318 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
319 basename of image when not present.
320 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
321 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
322 the other involving an undefined $is_folder error.
323 - Throw error when %Core.Encoding is set to a spurious value. Previously,
324 this errored silently and returned false.
325 - Redirected stderr to stdout for flush error output.
326 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
328 - Do not re-munge URL if the output URL has the same host as the input URL.
330 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
331 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
332 - Fix bug with inline elements in blockquotes conflicting with strict doctype
333 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
334 - Fix bug where dots and double-dots in absolute URLs without hostname were
335 not collapsed by URIFilter_MakeAbsolute.
336 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
337 by reordering their addition.
338 - Will now throw exception on many error conditions during lexer creation; also
339 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
341 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
342 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
343 Reported by David Morton.
344 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
345 for more interesting filter-backtracking
346 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
347 index to reprocess tokens.
348 . StringHashParser now allows for multiline sections with "empty" content;
349 previously the section would remain undefined.
350 . Added --quick option to multitest.php, which tests only the most recent
351 release for each series.
352 . Added --distro option to multitest.php, which accepts either 'normal' or
353 'standalone'. This supercedes --exclude-normal and --exclude-standalone
355 3.1.1, released 2008-06-19
356 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
357 In order to enable this again, please set %URI.MungeResources to true.
358 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
359 and height/width HTML with %HTML.MaxImgLength.
360 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
361 for sponsoring this feature. Check out the corresponding documentation
362 for details. (Att Nightly testers: The API for this feature changed before
363 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
364 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
365 ! Implemented post URI filtering. Set member variable $post to true to set
367 ! Allow modules to define injectors via $info_injector. Injectors are
368 automatically disabled if injector's needed elements are not found.
369 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
370 Thanks Chris for sponsoring. If you've been using ad hoc code from the
371 forums, PLEASE use this instead.
372 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
373 embedded, tag name, attribute name, CSS property name). See %URI.Munge
374 for more details. Requested by Jochem Blok.
375 - Disable percent height/width attributes for img.
376 - AttrValidator operations are now atomic; updates to attributes are not
377 manifest in token until end of operations. This prevents naughty internal
378 code from directly modifying CurrentToken when they're not supposed to.
379 This semantics change was requested by frank farmer.
380 - Percent encoding checks enabled for URI query and fragment
381 - Fix stray backslashes in font-family; CSS Unicode character escapes are
382 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
384 - Improve parseCDATA algorithm to take into account newline normalization
385 - Account for browser confusion between Yen character and backslash in
386 Shift_JIS encoding. This fix generalizes to any other encoding which is not
387 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
388 - Fix missing configuration parameter in Generator calls. Thanks vs for the
390 - Improved adherence to Unicode by checking for non-character codepoints.
391 Thanks Geoffrey Sneddon for reporting. This may result in degraded
392 performance for extremely large inputs.
393 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
395 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
396 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
398 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
399 to __construct($min, $max). __construct(true) is equivalent to
401 . Added HTMLPurifier_AttrDef_Switch class
402 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
403 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
404 get this called with the configuration object. All modules now
405 use this rather than __construct(), although legacy code using constructors
406 will still work--the new format, however, lets modules access the
407 configuration object for HTML namespace dependant tweaks.
408 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
409 . ConfigSchema data-structure heavily optimized; on average it uses a third
410 the memory it did previously. The interface has changed accordingly,
411 consult changes to HTMLPurifier_Config for details.
412 . Variable parsing types now are magic integers instead of strings
413 . Added benchmark for ConfigSchema
414 . HTMLPurifier_Generator requires $config and $context parameters. If you
415 don't know what they should be, use HTMLPurifier_Config::createDefault()
416 and new HTMLPurifier_Context().
417 . Printers now properly distinguish between output configuration, and
418 target configuration. This is not applicable to scripts using
419 the Printers for HTML Purifier related tasks.
420 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
421 fatal errors will ensue.
422 . URIFilter->prepare can return false in order to abort loading of the filter
423 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
424 an external resource.
425 . %URI.Munge functionality factored out into a post-filter class.
426 . Added CurrentCSSProperty context variable during CSS validation
428 3.1.0, released 2008-05-18
429 # Unnecessary references to objects (vestiges of PHP4) removed from method
430 signatures. The following methods do not need references when assigning from
431 them and will result in E_STRICT errors if you try:
432 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
433 + HTMLPurifier_ConfigSchema::instance()
434 + HTMLPurifier_DefinitionCacheFactory::instance()
435 + HTMLPurifier_DefinitionCacheFactory->create()
436 + HTMLPurifier_DoctypeRegistry->register()
437 + HTMLPurifier_DoctypeRegistry->get()
438 + HTMLPurifier_HTMLModule->addElement()
439 + HTMLPurifier_HTMLModule->addBlankElement()
440 + HTMLPurifier_LanguageFactory::instance()
441 # Printer_ConfigForm's get*() functions were static-ified
442 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
443 form of tag@attr, NOT tag.attr (which will throw an error and won't do
444 anything). This is for forwards compatibility with XML; you'd do best
445 to migrate an %HTML.AllowedAttributes directives to this syntax too.
446 ! Allow index to be false for config from form creation
447 ! Added HTMLPurifier::VERSION constant
448 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
449 and allows for version numbers like "3.1.0-dev".
450 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
451 ! HTML Purifier's URI handling is a lot more robust, with much stricter
452 validation checks and better percent encoding handling. Thanks Gareth Heyes
453 for indicating security vulnerabilities from lax percent encoding.
454 ! Bootstrap autoloader deals more robustly with classes that don't exist,
455 preventing class_exists($class, true) from barfing.
456 - InterchangeBuilder now alphabetizes its lists
457 - Validation error in configdoc output fixed
458 - Iconv and other encoding errors muted even with custom error handlers that
459 do not honor error_reporting
460 - Add protection against imagecrash attack with CSS height/width
461 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
462 - Fixed and revamped broken ConfigForm smoketest
463 - Bug with bool/null fields in Printer_ConfigForm fixed
464 - Bug with global forbidden attributes fixed
465 - Improved error messages for allowed and forbidden HTML elements and attributes
466 - Missing (or null) in configdoc documentation restored
467 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
468 of DOM), HTML Purifier punts to DirectLex
469 - Fatal error with unserialization of ScriptRequired
470 - Created directories are now chmod'ed properly
471 - Fixed bug with fallback languages in LanguageFactory
472 - Standalone testing setup properly with autoload
473 . Out-of-date documentation revised
474 . UTF-8 encoding check optimization as suggested by Diego
475 . HTMLPurifier_Error removed in favor of exceptions
476 . More copy() function removed; should use clone instead
477 . More extensive unit tests for HTMLDefinition

483 3.1.0rc1, released 2008-04-22
484 # Autoload support added. Internal require_once's removed in favor of an
485 explicit require list or autoloading. To use HTML Purifier,
486 you must now either use HTMLPurifier.auto.php
487 or HTMLPurifier.includes.php; setting the include path and including
488 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
489 as well to register our autoload handler (or modify your autoload function
490 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
491 HTMLPurifier.safe-includes.php for a less performance friendly but more
492 user-friendly library load.
493 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
494 information is stored in the ConfigSchema directory, and the
495 maintenance/generate-schema-cache.php generates the schema.ser file, which
496 is now instantiated. Support for userland schema changes coming soon!
497 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
498 alias; to get rid of these errors just modify your configuration to use
499 the new directive name.
500 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
501 enabled using %Filter.$filter_name or by setting your own filters using
503 # Directive-level safety properties superceded in favor of module-level
504 safety. Internal method HTMLModule->addElement() has changed, although
505 the externally visible HTMLDefinition->addElement has *not* changed.
506 ! Extra utility classes for testing and non-library operations can
507 be found in extras/. Specifically, these are FSTools and ConfigDoc.

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

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

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

744 linkify your HTML input by setting %AutoFormat.AutoParagraph and
745 %AutoFormat.Linkify to true
746 ! Newlines normalized internally, and then converted back to the
747 value of PHP_EOL. If this is not desired, set your newline format
748 using %Output.Newline.
749 ! Beta error collection, messages are implemented for the most generic
750 cases involving Lexing or Strategies
751 - Clean up special case code for <script> tags

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