1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.7.0, unknown release date
13 - Don't truncate upon encountering </div> when using DOMLex. Thanks
14 Myrto Christina for finally convincing me to fix this.
16 4.6.0, released 2013-11-30
17 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
18 Please update any verification scripts you may have.
19 # URI parsing algorithm was made more strict, so only prefixes which
20 looks like schemes will actually be schemes. Thanks
21 Michael Gusev <mgusev@sugarcrm.com> for fixing.
22 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
24 ! New directive %Core.AllowHostnameUnderscore which allows underscores
26 - Eliminate quadratic behavior in DOMLex by using a proper queue.
27 Thanks Ole Laursen for noticing this.
28 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
29 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
30 Networks for sponsoring this work.
31 - Made Linkify URL parser a bit less permissive, so that non-breaking
32 spaces and commas are not included as part of URL. Thanks nAS for fixing.
33 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
34 David Hirtz for reporting.
35 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
38 4.5.0, released 2013-02-17
39 # Fix bug where stacked attribute transforms clobber each other;
40 this also means it's no longer possible to override attribute
41 transforms in later modules. No internal code was using this
42 but this may break some clients.
43 # We now use SHA-1 to identify cached definitions, instead of MD5.
44 ! Support display:inline-block
45 ! Support for more white-space CSS values.
46 ! Permit underscores in font families
47 ! Support for page-break-* CSS3 properties when proprietary properties
49 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
50 SGML excludes checking. If HTML Purifier is removing too much text
51 and you don't care about full standards compliance, try setting this to
53 - Use prepend for SPL autoloading on PHP 5.3 and later.
54 - Fix bug with nofollow transform when pre-existing rel exists.
55 - Fix bug where background:url() always gets lower-cased
56 (but not background-image:url())
57 - Fix bug with non lower-case color names in HTML
58 - Fix bug where data URI validation doesn't remove temporary files.
59 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
60 - Don't remove certain empty tags on RemoveEmpty.
62 4.4.0, released 2012-01-18
63 # Removed PEARSax3 handler.
64 # URI.Munge now munges URIs inside the same host that go from https
65 to http. Reported by Neike Taika-Tessaro.
66 # Core.EscapeNonASCIICharacters now always transforms entities to
67 entities, even if target encoding is UTF-8.
68 # Tighten up selector validation in ExtractStyleBlocks.
69 Non-syntactically valid selectors are now rejected, along with
70 some of the more obscure ones such as attribute selectors, the
71 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
72 ID and class selectors now work properly with the relevant
73 configuration attributes. Also, mute errors when parsing CSS
74 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
75 ! Added support for 'scope' attribute on tables.
76 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
77 ! Properly handle sub-lists directly nested inside of lists in
78 a standards compliant way, by moving them into the preceding <li>
79 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
80 limited allowed comments in untrusted situations.
81 ! Implement iframes, and allow them to be used in untrusted mode with
82 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
83 <brad.froehle@gmail.com> for submitting an initial version of the patch.
84 ! The Forms module now works properly for transitional doctypes.
85 ! Added support for internationalized domain names. You need the PEAR
86 Net_IDNA2 module to be in your path; if it is installed, ensure the
87 class can be loaded and then set %Core.EnableIDNA to true.
88 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
89 <yramirez-htmlpurifier@adicio.com> for reporting.
90 - Explicitly initialize anonModule variable to null.
91 - Do not duplicate nofollow if already present. Thanks 178
93 - Do not add nofollow if hostname matches our current host. Thanks 178
94 for reporting, and Neike Taika-Tessaro for helping diagnose.
95 - Do not unset parser variable; this fixes intermittent serialization
96 problems. Thanks Neike Taika-Tessaro for reporting, bill
97 <10010tiger@gmail.com> for diagnosing.
98 - Fix iconv truncation bug, where non-UTF-8 target encodings see
99 output truncated after around 8000 characters. Thanks Jörg Ludwig
100 <joerg.ludwig@iserv.eu> for reporting.
101 - Fix broken table content model for XHTML1.1 (and also earlier
102 versions, although the W3C validator doesn't catch those violations).
103 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
105 4.3.0, released 2011-03-27
106 # Fixed broken caching of customized raw definitions, but requires an
107 API change. The old API still works but will emit a warning,
108 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
109 for how to upgrade your code.
110 # Protect against Internet Explorer innerHTML behavior by specially
111 treating attributes with backticks but no angled brackets, quotes or
112 spaces. This constitutes a slight semantic change, which can be
113 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
115 # Protect against cssText/innerHTML by restricting allowed characters
116 used in fonts further than mandated by the specification and encoding
117 some extra special characters in URLs. Reported by Neike
118 Taika-Tessaro and Mario Heiderich.
119 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
120 ! More types of SPL autoloaders allowed on later versions of PHP.
121 ! Implementations for position, top, left, right, bottom, z-index
122 when %CSS.Trusted is on.
123 ! Add %Cache.SerializerPermissions option for custom serializer
124 directory/file permissions
125 ! Fix longstanding bug in Flash support for non-IE browsers, and
126 allow more wmode attributes.
127 ! Add %CSS.AllowedFonts to restrict permissible font names.
128 - Switch to an iterative traversal of the DOM, which prevents us
129 from running out of stack space for deeply nested documents.
130 Thanks Maxim Krizhanovsky for contributing a patch.
131 - Make removal of conditional IE comments ungreedy; thanks Bernd
133 - Escape CDATA before removing Internet Explorer comments.
134 - Fix removal of id attributes under certain conditions by ensuring
135 armor attributes are preserved when recreating tags.
136 - Check if schema.ser was corrupted.
137 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
138 This safety check is only done for HTMLPurifier.auto.php; if you
139 are using standalone or the specialized includes files, you're
140 expected to know what you're doing.
141 - Stop repeatedly writing the cache file after I'm done customizing a
142 raw definition. Reported by ajh.
143 - Switch to using require_once in the Bootstrap to work around bad
144 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
145 - Fix URI handling when hostname is missing but scheme is present.
146 Reported by Neike Taika-Tessaro.
147 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
149 - Fix harmless notice from indexing into empty string. Thanks Matthijs
150 Kooijman <matthijs@stdin.nl> for reporting.
151 - Don't autoclose no parent elements are able to support the element
152 that triggered the autoclose. In particular fixes strange behavior
153 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
154 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
156 4.2.0, released 2010-09-15
157 ! Added %Core.RemoveProcessingInstructions, which lets you remove
158 <? ... ?> statements.
159 ! Added %URI.DisableResources functionality; the directive originally
160 did nothing. Thanks David Rothstein for reporting.
161 ! Add documentation about configuration directive types.
162 ! Add %CSS.ForbiddenProperties configuration directive.
163 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
164 to utilize full-screen mode.
165 ! Add optional support for the <code>file</code> URI scheme, enable
166 by explicitly setting %URI.AllowedSchemes.
167 ! Add %Core.NormalizeNewlines options to allow turning off newline
169 - Fix improper handling of Internet Explorer conditional comments
170 by parser. Thanks zmonteca for reporting.
171 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
172 Thanks sidepodcast for the fix.
173 - Warn if an element is allowed, but an attribute it requires is
176 4.1.1, released 2010-05-31
177 - Fix undefined index warnings in maintenance scripts.
178 - Fix bug in DirectLex for parsing elements with a single attribute
180 - Rewrite CSS output logic for font-family and url(). Thanks Mario
181 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
182 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
183 - Emit an error for CollectErrors if a body is extracted
184 - Fix bug where in background-position for center keyword handling.
185 - Fix infinite loop when a wrapper element is inserted in a context
186 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
187 - Remove +x bit and shebang from index.php; only supported mode is to
188 explicitly call it with php.
189 - Make test script less chatty when log_errors is on.
191 4.1.0, released 2010-04-26
192 ! Support proprietary height attribute on table element
193 ! Support YouTube slideshows that contain /cp/ in their URL.
194 ! Support for data: URI scheme; not enabled by default, add it using
196 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
197 ! Support for Internet Explorer compatibility with %HTML.SafeObject
198 using %Output.FlashCompat.
199 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
200 - Always quote the insides of url(...) in CSS.
202 4.0.0, released 2009-07-07
203 # APIs for ConfigSchema subsystem have substantially changed. See
204 docs/dev-config-bcbreaks.txt for details; in essence, anything that
205 had both namespace and directive now have a single unified key.
206 # Some configuration directives were renamed, specifically:
207 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
208 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
209 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
210 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
211 As usual, the old directive names will still work, but will throw E_NOTICE
213 # The allowed values for class have been relaxed to allow all of CDATA for
214 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
215 %Attr.ClassUseCDATA to false.
216 # Instead of appending the content model to an old content model, a blank
217 element will replace the old content model. You can use #SUPER to get
218 the old content model.
219 ! More robust support for name="" and id=""
220 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
221 configuration, and have changes to that configuration be propagated
222 to all of its children.
223 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
224 the name attribute when set. Use with care. Thanks Ian Cook for
226 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
227 tags that contain non-breaking spaces as well other whitespace. You
228 can also modify which tags should have maintained with
229 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
230 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
231 classes users can use to a specified finite set of classes, and
232 %Attr.ForbiddenClasses, which is the logical inverse.
233 ! You can now maintain your own configuration schema directories by
234 creating a config-schema.php file or passing an extra argument. Check
235 docs/dev-config-schema.html for more details.
236 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
237 your configuration in a compact serial file, which you can unserialize
238 and use directly without having to go through the overhead of setup.
239 - Fix bug where URIDefinition would not get cleared if it's directives got
241 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
242 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
243 - Make %URI.Munge not apply to links that have the same host as your host.
244 - Prevent stray </body> tag from truncating output, if a second </body>
246 . Created script maintenance/rename-config.php for renaming a configuration
247 directive while maintaining its alias. This script does not change source code.
248 . Implement namespace locking for definition construction, to prevent
249 bugs where a directive is used for definition construction but is not
250 used to construct the cache hash.
252 3.3.0, released 2009-02-16
253 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
254 ! Implement generic property list classess
255 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
256 does not do the "right thing" with characters not supported in the output
258 - Spellcheck UTF-8: The Secret To Character Encoding
259 - Fix improper removal of the contents of elements with only whitespace. Thanks
260 Eric Wald for reporting.
261 - Fix broken test suite in versions of PHP without spl_autoload_register()
262 - Fix degenerate case with YouTube filter involving double hyphens.
263 Thanks Pierre Attar for reporting.
264 - Fix YouTube rendering problem on certain versions of Firefox.
265 - Fix CSSDefinition Printer problems with decorators
266 - Add text parameter to unit tests, forces text output
267 . Add verbose mode to command line test runner, use (--verbose)
268 . Turn on unit tests for UnitConverter
269 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
270 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
272 . Removed trailing whitespace from all text files, see
273 remote-trailing-whitespace.php maintenance script.
274 . Convert configuration to use property list backend.
276 3.2.0, released 2008-10-31
277 # Using %Core.CollectErrors forces line number/column tracking on, whereas
278 previously you could theoretically turn it off.
279 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
280 use handleEnd() instead.
281 ! %Output.AttrSort for when you need your attributes in alphabetical order to
282 deal with a bug in FCKEditor. Requested by frank farmer.
283 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
284 ! Proper support for name attribute. It is now allowed and equivalent to the id
285 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
286 is heavy (for all doctypes).
287 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
288 use on hand-written HTML.
289 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
290 the strategy to be used, standalone, on untrusted input.
291 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
292 processing of left angled brackets in smileys and other whatnot.
293 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
294 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
295 the --only-phpt parameter, although for backwards-compatibility the flag
297 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
298 Users who are not performing inbound filtering, this may seem a little
299 useless, but as a bonus, the test suite and handling of edge cases is also
301 ! Experimental implementation of forms for %HTML.Trusted
302 ! Track column numbers when maintain line numbers is on
303 ! Proprietary 'background' attribute on table-related elements converted into
304 corresponding CSS. Thanks Fusemail for sponsoring this feature!
305 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
307 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
308 time of operation varies slightly from notifyEnd() as *all* end tokens are
309 processed by the injector before they are subject to the well-formedness rules.
310 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
311 basename of image when not present.
312 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
313 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
314 the other involving an undefined $is_folder error.
315 - Throw error when %Core.Encoding is set to a spurious value. Previously,
316 this errored silently and returned false.
317 - Redirected stderr to stdout for flush error output.
318 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
320 - Do not re-munge URL if the output URL has the same host as the input URL.
322 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
323 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
324 - Fix bug with inline elements in blockquotes conflicting with strict doctype
325 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
326 - Fix bug where dots and double-dots in absolute URLs without hostname were
327 not collapsed by URIFilter_MakeAbsolute.
328 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
329 by reordering their addition.
330 - Will now throw exception on many error conditions during lexer creation; also
331 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
333 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
334 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
335 Reported by David Morton.
336 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
337 for more interesting filter-backtracking
338 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
339 index to reprocess tokens.
340 . StringHashParser now allows for multiline sections with "empty" content;
341 previously the section would remain undefined.
342 . Added --quick option to multitest.php, which tests only the most recent
343 release for each series.
344 . Added --distro option to multitest.php, which accepts either 'normal' or
345 'standalone'. This supercedes --exclude-normal and --exclude-standalone
347 3.1.1, released 2008-06-19
348 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
349 In order to enable this again, please set %URI.MungeResources to true.
350 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
351 and height/width HTML with %HTML.MaxImgLength.
352 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
353 for sponsoring this feature. Check out the corresponding documentation
354 for details. (Att Nightly testers: The API for this feature changed before
355 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
356 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
357 ! Implemented post URI filtering. Set member variable $post to true to set
359 ! Allow modules to define injectors via $info_injector. Injectors are
360 automatically disabled if injector's needed elements are not found.
361 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
362 Thanks Chris for sponsoring. If you've been using ad hoc code from the
363 forums, PLEASE use this instead.
364 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
365 embedded, tag name, attribute name, CSS property name). See %URI.Munge
366 for more details. Requested by Jochem Blok.
367 - Disable percent height/width attributes for img.
368 - AttrValidator operations are now atomic; updates to attributes are not
369 manifest in token until end of operations. This prevents naughty internal
370 code from directly modifying CurrentToken when they're not supposed to.
371 This semantics change was requested by frank farmer.
372 - Percent encoding checks enabled for URI query and fragment
373 - Fix stray backslashes in font-family; CSS Unicode character escapes are
374 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
376 - Improve parseCDATA algorithm to take into account newline normalization
377 - Account for browser confusion between Yen character and backslash in
378 Shift_JIS encoding. This fix generalizes to any other encoding which is not
379 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
380 - Fix missing configuration parameter in Generator calls. Thanks vs for the
382 - Improved adherence to Unicode by checking for non-character codepoints.
383 Thanks Geoffrey Sneddon for reporting. This may result in degraded
384 performance for extremely large inputs.
385 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
387 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
388 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
390 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
391 to __construct($min, $max). __construct(true) is equivalent to
393 . Added HTMLPurifier_AttrDef_Switch class
394 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
395 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
396 get this called with the configuration object. All modules now
397 use this rather than __construct(), although legacy code using constructors
398 will still work--the new format, however, lets modules access the
399 configuration object for HTML namespace dependant tweaks.
400 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
401 . ConfigSchema data-structure heavily optimized; on average it uses a third
402 the memory it did previously. The interface has changed accordingly,
403 consult changes to HTMLPurifier_Config for details.
404 . Variable parsing types now are magic integers instead of strings
405 . Added benchmark for ConfigSchema
406 . HTMLPurifier_Generator requires $config and $context parameters. If you
407 don't know what they should be, use HTMLPurifier_Config::createDefault()
408 and new HTMLPurifier_Context().
409 . Printers now properly distinguish between output configuration, and
410 target configuration. This is not applicable to scripts using
411 the Printers for HTML Purifier related tasks.
412 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
413 fatal errors will ensue.
414 . URIFilter->prepare can return false in order to abort loading of the filter
415 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
416 an external resource.
417 . %URI.Munge functionality factored out into a post-filter class.
418 . Added CurrentCSSProperty context variable during CSS validation
420 3.1.0, released 2008-05-18
421 # Unnecessary references to objects (vestiges of PHP4) removed from method
422 signatures. The following methods do not need references when assigning from
423 them and will result in E_STRICT errors if you try:
424 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
425 + HTMLPurifier_ConfigSchema::instance()
426 + HTMLPurifier_DefinitionCacheFactory::instance()
427 + HTMLPurifier_DefinitionCacheFactory->create()
428 + HTMLPurifier_DoctypeRegistry->register()
429 + HTMLPurifier_DoctypeRegistry->get()
430 + HTMLPurifier_HTMLModule->addElement()
431 + HTMLPurifier_HTMLModule->addBlankElement()
432 + HTMLPurifier_LanguageFactory::instance()
433 # Printer_ConfigForm's get*() functions were static-ified
434 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
435 form of tag@attr, NOT tag.attr (which will throw an error and won't do
436 anything). This is for forwards compatibility with XML; you'd do best
437 to migrate an %HTML.AllowedAttributes directives to this syntax too.
438 ! Allow index to be false for config from form creation
439 ! Added HTMLPurifier::VERSION constant
440 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
441 and allows for version numbers like "3.1.0-dev".
442 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
443 ! HTML Purifier's URI handling is a lot more robust, with much stricter
444 validation checks and better percent encoding handling. Thanks Gareth Heyes
445 for indicating security vulnerabilities from lax percent encoding.
446 ! Bootstrap autoloader deals more robustly with classes that don't exist,
447 preventing class_exists($class, true) from barfing.
448 - InterchangeBuilder now alphabetizes its lists
449 - Validation error in configdoc output fixed
450 - Iconv and other encoding errors muted even with custom error handlers that
451 do not honor error_reporting
452 - Add protection against imagecrash attack with CSS height/width
453 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
454 - Fixed and revamped broken ConfigForm smoketest
455 - Bug with bool/null fields in Printer_ConfigForm fixed
456 - Bug with global forbidden attributes fixed
457 - Improved error messages for allowed and forbidden HTML elements and attributes
458 - Missing (or null) in configdoc documentation restored
459 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
460 of DOM), HTML Purifier punts to DirectLex
461 - Fatal error with unserialization of ScriptRequired
462 - Created directories are now chmod'ed properly
463 - Fixed bug with fallback languages in LanguageFactory
464 - Standalone testing setup properly with autoload
465 . Out-of-date documentation revised
466 . UTF-8 encoding check optimization as suggested by Diego
467 . HTMLPurifier_Error removed in favor of exceptions
468 . More copy() function removed; should use clone instead
469 . More extensive unit tests for HTMLDefinition
470 . assertPurification moved to central harness
471 . HTMLPurifier_Generator accepts $config and $context parameters during
472 instantiation, not runtime
473 . Double-quotes outside of attribute values are now unescaped
475 3.1.0rc1, released 2008-04-22
476 # Autoload support added. Internal require_once's removed in favor of an
477 explicit require list or autoloading. To use HTML Purifier,
478 you must now either use HTMLPurifier.auto.php
479 or HTMLPurifier.includes.php; setting the include path and including
480 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
481 as well to register our autoload handler (or modify your autoload function
482 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
483 HTMLPurifier.safe-includes.php for a less performance friendly but more
484 user-friendly library load.
485 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
486 information is stored in the ConfigSchema directory, and the
487 maintenance/generate-schema-cache.php generates the schema.ser file, which
488 is now instantiated. Support for userland schema changes coming soon!
489 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
490 alias; to get rid of these errors just modify your configuration to use
491 the new directive name.
492 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
493 enabled using %Filter.$filter_name or by setting your own filters using
495 # Directive-level safety properties superceded in favor of module-level
496 safety. Internal method HTMLModule->addElement() has changed, although
497 the externally visible HTMLDefinition->addElement has *not* changed.
498 ! Extra utility classes for testing and non-library operations can
499 be found in extras/. Specifically, these are FSTools and ConfigDoc.

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