1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.8.0, unknown release date
13 ! %CSS.AllowDuplicates permits duplicate CSS properties.
14 - alt truncation could result in malformed UTF-8 sequence. Don't
15 truncate. Thanks Brandon Farber for reporting.
17 4.7.0, released 2015-08-04
18 # opacity is now considered a "tricky" CSS property rather than a
20 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
21 an element should be considered "empty" (maybe preserve if it
22 has attributes), and modify iframe support so that the iframe
23 is removed if it is missing a src attribute. Thanks meeva for
25 - Don't truncate upon encountering </div> when using DOMLex. Thanks
26 Myrto Christina for finally convincing me to fix this.
27 - Update YouTube filter for new code.
28 - Fix parsing of rgb() values with spaces in them for 'border'
30 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
33 4.6.0, released 2013-11-30
34 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
35 Please update any verification scripts you may have.
36 # URI parsing algorithm was made more strict, so only prefixes which
37 looks like schemes will actually be schemes. Thanks
38 Michael Gusev <mgusev@sugarcrm.com> for fixing.
39 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
41 ! New directive %Core.AllowHostnameUnderscore which allows underscores
43 - Eliminate quadratic behavior in DOMLex by using a proper queue.
44 Thanks Ole Laursen for noticing this.
45 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
46 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
47 Networks for sponsoring this work.
48 - Made Linkify URL parser a bit less permissive, so that non-breaking
49 spaces and commas are not included as part of URL. Thanks nAS for fixing.
50 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
51 David Hirtz for reporting.
52 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
55 4.5.0, released 2013-02-17
56 # Fix bug where stacked attribute transforms clobber each other;
57 this also means it's no longer possible to override attribute
58 transforms in later modules. No internal code was using this
59 but this may break some clients.
60 # We now use SHA-1 to identify cached definitions, instead of MD5.
61 ! Support display:inline-block
62 ! Support for more white-space CSS values.
63 ! Permit underscores in font families
64 ! Support for page-break-* CSS3 properties when proprietary properties
66 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
67 SGML excludes checking. If HTML Purifier is removing too much text
68 and you don't care about full standards compliance, try setting this to
70 - Use prepend for SPL autoloading on PHP 5.3 and later.
71 - Fix bug with nofollow transform when pre-existing rel exists.
72 - Fix bug where background:url() always gets lower-cased
73 (but not background-image:url())
74 - Fix bug with non lower-case color names in HTML
75 - Fix bug where data URI validation doesn't remove temporary files.
76 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
77 - Don't remove certain empty tags on RemoveEmpty.
79 4.4.0, released 2012-01-18
80 # Removed PEARSax3 handler.
81 # URI.Munge now munges URIs inside the same host that go from https
82 to http. Reported by Neike Taika-Tessaro.
83 # Core.EscapeNonASCIICharacters now always transforms entities to
84 entities, even if target encoding is UTF-8.
85 # Tighten up selector validation in ExtractStyleBlocks.
86 Non-syntactically valid selectors are now rejected, along with
87 some of the more obscure ones such as attribute selectors, the
88 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
89 ID and class selectors now work properly with the relevant
90 configuration attributes. Also, mute errors when parsing CSS
91 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
92 ! Added support for 'scope' attribute on tables.
93 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
94 ! Properly handle sub-lists directly nested inside of lists in
95 a standards compliant way, by moving them into the preceding <li>
96 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
97 limited allowed comments in untrusted situations.
98 ! Implement iframes, and allow them to be used in untrusted mode with
99 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
100 <brad.froehle@gmail.com> for submitting an initial version of the patch.
101 ! The Forms module now works properly for transitional doctypes.
102 ! Added support for internationalized domain names. You need the PEAR
103 Net_IDNA2 module to be in your path; if it is installed, ensure the
104 class can be loaded and then set %Core.EnableIDNA to true.
105 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
106 <yramirez-htmlpurifier@adicio.com> for reporting.
107 - Explicitly initialize anonModule variable to null.
108 - Do not duplicate nofollow if already present. Thanks 178
110 - Do not add nofollow if hostname matches our current host. Thanks 178
111 for reporting, and Neike Taika-Tessaro for helping diagnose.
112 - Do not unset parser variable; this fixes intermittent serialization
113 problems. Thanks Neike Taika-Tessaro for reporting, bill
114 <10010tiger@gmail.com> for diagnosing.
115 - Fix iconv truncation bug, where non-UTF-8 target encodings see
116 output truncated after around 8000 characters. Thanks Jörg Ludwig
117 <joerg.ludwig@iserv.eu> for reporting.
118 - Fix broken table content model for XHTML1.1 (and also earlier
119 versions, although the W3C validator doesn't catch those violations).
120 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
122 4.3.0, released 2011-03-27
123 # Fixed broken caching of customized raw definitions, but requires an
124 API change. The old API still works but will emit a warning,
125 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
126 for how to upgrade your code.
127 # Protect against Internet Explorer innerHTML behavior by specially
128 treating attributes with backticks but no angled brackets, quotes or
129 spaces. This constitutes a slight semantic change, which can be
130 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
132 # Protect against cssText/innerHTML by restricting allowed characters
133 used in fonts further than mandated by the specification and encoding
134 some extra special characters in URLs. Reported by Neike
135 Taika-Tessaro and Mario Heiderich.
136 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
137 ! More types of SPL autoloaders allowed on later versions of PHP.
138 ! Implementations for position, top, left, right, bottom, z-index
139 when %CSS.Trusted is on.
140 ! Add %Cache.SerializerPermissions option for custom serializer
141 directory/file permissions
142 ! Fix longstanding bug in Flash support for non-IE browsers, and
143 allow more wmode attributes.
144 ! Add %CSS.AllowedFonts to restrict permissible font names.
145 - Switch to an iterative traversal of the DOM, which prevents us
146 from running out of stack space for deeply nested documents.
147 Thanks Maxim Krizhanovsky for contributing a patch.
148 - Make removal of conditional IE comments ungreedy; thanks Bernd
150 - Escape CDATA before removing Internet Explorer comments.
151 - Fix removal of id attributes under certain conditions by ensuring
152 armor attributes are preserved when recreating tags.
153 - Check if schema.ser was corrupted.
154 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
155 This safety check is only done for HTMLPurifier.auto.php; if you
156 are using standalone or the specialized includes files, you're
157 expected to know what you're doing.
158 - Stop repeatedly writing the cache file after I'm done customizing a
159 raw definition. Reported by ajh.
160 - Switch to using require_once in the Bootstrap to work around bad
161 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
162 - Fix URI handling when hostname is missing but scheme is present.
163 Reported by Neike Taika-Tessaro.
164 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
166 - Fix harmless notice from indexing into empty string. Thanks Matthijs
167 Kooijman <matthijs@stdin.nl> for reporting.
168 - Don't autoclose no parent elements are able to support the element
169 that triggered the autoclose. In particular fixes strange behavior
170 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
171 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
173 4.2.0, released 2010-09-15
174 ! Added %Core.RemoveProcessingInstructions, which lets you remove
175 <? ... ?> statements.
176 ! Added %URI.DisableResources functionality; the directive originally
177 did nothing. Thanks David Rothstein for reporting.
178 ! Add documentation about configuration directive types.
179 ! Add %CSS.ForbiddenProperties configuration directive.
180 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
181 to utilize full-screen mode.
182 ! Add optional support for the <code>file</code> URI scheme, enable
183 by explicitly setting %URI.AllowedSchemes.
184 ! Add %Core.NormalizeNewlines options to allow turning off newline
186 - Fix improper handling of Internet Explorer conditional comments
187 by parser. Thanks zmonteca for reporting.
188 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
189 Thanks sidepodcast for the fix.
190 - Warn if an element is allowed, but an attribute it requires is
193 4.1.1, released 2010-05-31
194 - Fix undefined index warnings in maintenance scripts.
195 - Fix bug in DirectLex for parsing elements with a single attribute
197 - Rewrite CSS output logic for font-family and url(). Thanks Mario
198 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
199 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
200 - Emit an error for CollectErrors if a body is extracted
201 - Fix bug where in background-position for center keyword handling.
202 - Fix infinite loop when a wrapper element is inserted in a context
203 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
204 - Remove +x bit and shebang from index.php; only supported mode is to
205 explicitly call it with php.
206 - Make test script less chatty when log_errors is on.
208 4.1.0, released 2010-04-26
209 ! Support proprietary height attribute on table element
210 ! Support YouTube slideshows that contain /cp/ in their URL.
211 ! Support for data: URI scheme; not enabled by default, add it using
213 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
214 ! Support for Internet Explorer compatibility with %HTML.SafeObject
215 using %Output.FlashCompat.
216 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
217 - Always quote the insides of url(...) in CSS.
219 4.0.0, released 2009-07-07
220 # APIs for ConfigSchema subsystem have substantially changed. See
221 docs/dev-config-bcbreaks.txt for details; in essence, anything that
222 had both namespace and directive now have a single unified key.
223 # Some configuration directives were renamed, specifically:
224 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
225 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
226 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
227 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
228 As usual, the old directive names will still work, but will throw E_NOTICE
230 # The allowed values for class have been relaxed to allow all of CDATA for
231 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
232 %Attr.ClassUseCDATA to false.
233 # Instead of appending the content model to an old content model, a blank
234 element will replace the old content model. You can use #SUPER to get
235 the old content model.
236 ! More robust support for name="" and id=""
237 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
238 configuration, and have changes to that configuration be propagated
239 to all of its children.
240 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
241 the name attribute when set. Use with care. Thanks Ian Cook for
243 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
244 tags that contain non-breaking spaces as well other whitespace. You
245 can also modify which tags should have maintained with
246 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
247 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
248 classes users can use to a specified finite set of classes, and
249 %Attr.ForbiddenClasses, which is the logical inverse.
250 ! You can now maintain your own configuration schema directories by
251 creating a config-schema.php file or passing an extra argument. Check
252 docs/dev-config-schema.html for more details.
253 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
254 your configuration in a compact serial file, which you can unserialize
255 and use directly without having to go through the overhead of setup.
256 - Fix bug where URIDefinition would not get cleared if it's directives got
258 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
259 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
260 - Make %URI.Munge not apply to links that have the same host as your host.
261 - Prevent stray </body> tag from truncating output, if a second </body>
263 . Created script maintenance/rename-config.php for renaming a configuration
264 directive while maintaining its alias. This script does not change source code.
265 . Implement namespace locking for definition construction, to prevent
266 bugs where a directive is used for definition construction but is not
267 used to construct the cache hash.
269 3.3.0, released 2009-02-16
270 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
271 ! Implement generic property list classess
272 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
273 does not do the "right thing" with characters not supported in the output
275 - Spellcheck UTF-8: The Secret To Character Encoding
276 - Fix improper removal of the contents of elements with only whitespace. Thanks
277 Eric Wald for reporting.
278 - Fix broken test suite in versions of PHP without spl_autoload_register()
279 - Fix degenerate case with YouTube filter involving double hyphens.
280 Thanks Pierre Attar for reporting.
281 - Fix YouTube rendering problem on certain versions of Firefox.
282 - Fix CSSDefinition Printer problems with decorators
283 - Add text parameter to unit tests, forces text output
284 . Add verbose mode to command line test runner, use (--verbose)
285 . Turn on unit tests for UnitConverter
286 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
287 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
289 . Removed trailing whitespace from all text files, see
290 remote-trailing-whitespace.php maintenance script.
291 . Convert configuration to use property list backend.
293 3.2.0, released 2008-10-31
294 # Using %Core.CollectErrors forces line number/column tracking on, whereas
295 previously you could theoretically turn it off.
296 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
297 use handleEnd() instead.
298 ! %Output.AttrSort for when you need your attributes in alphabetical order to
299 deal with a bug in FCKEditor. Requested by frank farmer.
300 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
301 ! Proper support for name attribute. It is now allowed and equivalent to the id
302 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
303 is heavy (for all doctypes).
304 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
305 use on hand-written HTML.
306 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
307 the strategy to be used, standalone, on untrusted input.
308 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
309 processing of left angled brackets in smileys and other whatnot.
310 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
311 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
312 the --only-phpt parameter, although for backwards-compatibility the flag
314 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
315 Users who are not performing inbound filtering, this may seem a little
316 useless, but as a bonus, the test suite and handling of edge cases is also
318 ! Experimental implementation of forms for %HTML.Trusted
319 ! Track column numbers when maintain line numbers is on
320 ! Proprietary 'background' attribute on table-related elements converted into
321 corresponding CSS. Thanks Fusemail for sponsoring this feature!
322 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
324 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
325 time of operation varies slightly from notifyEnd() as *all* end tokens are
326 processed by the injector before they are subject to the well-formedness rules.
327 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
328 basename of image when not present.
329 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
330 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
331 the other involving an undefined $is_folder error.
332 - Throw error when %Core.Encoding is set to a spurious value. Previously,
333 this errored silently and returned false.
334 - Redirected stderr to stdout for flush error output.
335 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
337 - Do not re-munge URL if the output URL has the same host as the input URL.
339 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
340 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
341 - Fix bug with inline elements in blockquotes conflicting with strict doctype
342 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
343 - Fix bug where dots and double-dots in absolute URLs without hostname were
344 not collapsed by URIFilter_MakeAbsolute.
345 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
346 by reordering their addition.
347 - Will now throw exception on many error conditions during lexer creation; also
348 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
350 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
351 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
352 Reported by David Morton.
353 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
354 for more interesting filter-backtracking
355 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
356 index to reprocess tokens.
357 . StringHashParser now allows for multiline sections with "empty" content;
358 previously the section would remain undefined.
359 . Added --quick option to multitest.php, which tests only the most recent
360 release for each series.
361 . Added --distro option to multitest.php, which accepts either 'normal' or
362 'standalone'. This supercedes --exclude-normal and --exclude-standalone
364 3.1.1, released 2008-06-19
365 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
366 In order to enable this again, please set %URI.MungeResources to true.
367 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
368 and height/width HTML with %HTML.MaxImgLength.
369 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
370 for sponsoring this feature. Check out the corresponding documentation
371 for details. (Att Nightly testers: The API for this feature changed before
372 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
373 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
374 ! Implemented post URI filtering. Set member variable $post to true to set
376 ! Allow modules to define injectors via $info_injector. Injectors are
377 automatically disabled if injector's needed elements are not found.
378 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
379 Thanks Chris for sponsoring. If you've been using ad hoc code from the
380 forums, PLEASE use this instead.
381 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
382 embedded, tag name, attribute name, CSS property name). See %URI.Munge
383 for more details. Requested by Jochem Blok.
384 - Disable percent height/width attributes for img.
385 - AttrValidator operations are now atomic; updates to attributes are not
386 manifest in token until end of operations. This prevents naughty internal
387 code from directly modifying CurrentToken when they're not supposed to.
388 This semantics change was requested by frank farmer.
389 - Percent encoding checks enabled for URI query and fragment
390 - Fix stray backslashes in font-family; CSS Unicode character escapes are
391 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
393 - Improve parseCDATA algorithm to take into account newline normalization
394 - Account for browser confusion between Yen character and backslash in
395 Shift_JIS encoding. This fix generalizes to any other encoding which is not
396 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
397 - Fix missing configuration parameter in Generator calls. Thanks vs for the
399 - Improved adherence to Unicode by checking for non-character codepoints.
400 Thanks Geoffrey Sneddon for reporting. This may result in degraded
401 performance for extremely large inputs.
402 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
404 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
405 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
407 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
408 to __construct($min, $max). __construct(true) is equivalent to
410 . Added HTMLPurifier_AttrDef_Switch class
411 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
412 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
413 get this called with the configuration object. All modules now
414 use this rather than __construct(), although legacy code using constructors
415 will still work--the new format, however, lets modules access the
416 configuration object for HTML namespace dependant tweaks.
417 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
418 . ConfigSchema data-structure heavily optimized; on average it uses a third
419 the memory it did previously. The interface has changed accordingly,
420 consult changes to HTMLPurifier_Config for details.
421 . Variable parsing types now are magic integers instead of strings
422 . Added benchmark for ConfigSchema
423 . HTMLPurifier_Generator requires $config and $context parameters. If you
424 don't know what they should be, use HTMLPurifier_Config::createDefault()
425 and new HTMLPurifier_Context().
426 . Printers now properly distinguish between output configuration, and
427 target configuration. This is not applicable to scripts using
428 the Printers for HTML Purifier related tasks.
429 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
430 fatal errors will ensue.
431 . URIFilter->prepare can return false in order to abort loading of the filter
432 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
433 an external resource.
434 . %URI.Munge functionality factored out into a post-filter class.
435 . Added CurrentCSSProperty context variable during CSS validation
437 3.1.0, released 2008-05-18
438 # Unnecessary references to objects (vestiges of PHP4) removed from method
439 signatures. The following methods do not need references when assigning from
440 them and will result in E_STRICT errors if you try:
441 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
442 + HTMLPurifier_ConfigSchema::instance()
443 + HTMLPurifier_DefinitionCacheFactory::instance()
444 + HTMLPurifier_DefinitionCacheFactory->create()
445 + HTMLPurifier_DoctypeRegistry->register()
446 + HTMLPurifier_DoctypeRegistry->get()
447 + HTMLPurifier_HTMLModule->addElement()
448 + HTMLPurifier_HTMLModule->addBlankElement()
449 + HTMLPurifier_LanguageFactory::instance()
450 # Printer_ConfigForm's get*() functions were static-ified
451 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
452 form of tag@attr, NOT tag.attr (which will throw an error and won't do
453 anything). This is for forwards compatibility with XML; you'd do best
454 to migrate an %HTML.AllowedAttributes directives to this syntax too.
455 ! Allow index to be false for config from form creation
456 ! Added HTMLPurifier::VERSION constant
457 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
458 and allows for version numbers like "3.1.0-dev".
459 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
460 ! HTML Purifier's URI handling is a lot more robust, with much stricter
461 validation checks and better percent encoding handling. Thanks Gareth Heyes
462 for indicating security vulnerabilities from lax percent encoding.
463 ! Bootstrap autoloader deals more robustly with classes that don't exist,
464 preventing class_exists($class, true) from barfing.
465 - InterchangeBuilder now alphabetizes its lists
466 - Validation error in configdoc output fixed
467 - Iconv and other encoding errors muted even with custom error handlers that
468 do not honor error_reporting
469 - Add protection against imagecrash attack with CSS height/width
470 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
471 - Fixed and revamped broken ConfigForm smoketest
472 - Bug with bool/null fields in Printer_ConfigForm fixed
473 - Bug with global forbidden attributes fixed
474 - Improved error messages for allowed and forbidden HTML elements and attributes
475 - Missing (or null) in configdoc documentation restored
476 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
477 of DOM), HTML Purifier punts to DirectLex

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

520 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
521 by Chris. You can enable them with %HTML.Proprietary if your client

641 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
642 to better communicate its purpose
643 . Error unit tests can now specify the expectation of no errors. Future
644 iterations of the harness will be extremely strict about what errors

666 namespace. Also, this is PHP5 only.
667 ! CSS property border-spacing implemented
668 - Fix non-visible parsing error in DirectLex with empty tags that have
669 slashes inside attribute values.
670 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
671 accepted as valid CSS. Usually non-visible, because this styling is the
672 default for tables in most browsers. Thanks Brett Zamir for pointing
674 - Fix validation errors in configuration form

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

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

753 linkify your HTML input by setting %AutoFormat.AutoParagraph and
754 %AutoFormat.Linkify to true
755 ! Newlines normalized internally, and then converted back to the
756 value of PHP_EOL. If this is not desired, set your newline format
757 using %Output.Newline.
758 ! Beta error collection, messages are implemented for the most generic
759 cases involving Lexing or Strategies

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