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.
16 - Linkify regex is smarter, based off of Gruber's regex.
17 - IDNA supported natively on PHP 5.3 and later.
19 4.7.0, released 2015-08-04
20 # opacity is now considered a "tricky" CSS property rather than a
22 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
23 an element should be considered "empty" (maybe preserve if it
24 has attributes), and modify iframe support so that the iframe
25 is removed if it is missing a src attribute. Thanks meeva for
27 - Don't truncate upon encountering </div> when using DOMLex. Thanks
28 Myrto Christina for finally convincing me to fix this.
29 - Update YouTube filter for new code.
30 - Fix parsing of rgb() values with spaces in them for 'border'
32 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
35 4.6.0, released 2013-11-30
36 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
37 Please update any verification scripts you may have.
38 # URI parsing algorithm was made more strict, so only prefixes which
39 looks like schemes will actually be schemes. Thanks
40 Michael Gusev <mgusev@sugarcrm.com> for fixing.
41 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
43 ! New directive %Core.AllowHostnameUnderscore which allows underscores
45 - Eliminate quadratic behavior in DOMLex by using a proper queue.
46 Thanks Ole Laursen for noticing this.
47 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
48 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
49 Networks for sponsoring this work.
50 - Made Linkify URL parser a bit less permissive, so that non-breaking
51 spaces and commas are not included as part of URL. Thanks nAS for fixing.
52 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
53 David Hirtz for reporting.
54 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
57 4.5.0, released 2013-02-17
58 # Fix bug where stacked attribute transforms clobber each other;
59 this also means it's no longer possible to override attribute
60 transforms in later modules. No internal code was using this
61 but this may break some clients.
62 # We now use SHA-1 to identify cached definitions, instead of MD5.
63 ! Support display:inline-block
64 ! Support for more white-space CSS values.
65 ! Permit underscores in font families
66 ! Support for page-break-* CSS3 properties when proprietary properties
68 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
69 SGML excludes checking. If HTML Purifier is removing too much text
70 and you don't care about full standards compliance, try setting this to
72 - Use prepend for SPL autoloading on PHP 5.3 and later.
73 - Fix bug with nofollow transform when pre-existing rel exists.
74 - Fix bug where background:url() always gets lower-cased
75 (but not background-image:url())
76 - Fix bug with non lower-case color names in HTML
77 - Fix bug where data URI validation doesn't remove temporary files.
78 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
79 - Don't remove certain empty tags on RemoveEmpty.
81 4.4.0, released 2012-01-18
82 # Removed PEARSax3 handler.
83 # URI.Munge now munges URIs inside the same host that go from https
84 to http. Reported by Neike Taika-Tessaro.
85 # Core.EscapeNonASCIICharacters now always transforms entities to
86 entities, even if target encoding is UTF-8.
87 # Tighten up selector validation in ExtractStyleBlocks.
88 Non-syntactically valid selectors are now rejected, along with
89 some of the more obscure ones such as attribute selectors, the
90 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
91 ID and class selectors now work properly with the relevant
92 configuration attributes. Also, mute errors when parsing CSS
93 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
94 ! Added support for 'scope' attribute on tables.
95 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
96 ! Properly handle sub-lists directly nested inside of lists in
97 a standards compliant way, by moving them into the preceding <li>
98 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
99 limited allowed comments in untrusted situations.
100 ! Implement iframes, and allow them to be used in untrusted mode with
101 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
102 <brad.froehle@gmail.com> for submitting an initial version of the patch.
103 ! The Forms module now works properly for transitional doctypes.
104 ! Added support for internationalized domain names. You need the PEAR
105 Net_IDNA2 module to be in your path; if it is installed, ensure the
106 class can be loaded and then set %Core.EnableIDNA to true.
107 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
108 <yramirez-htmlpurifier@adicio.com> for reporting.
109 - Explicitly initialize anonModule variable to null.
110 - Do not duplicate nofollow if already present. Thanks 178
112 - Do not add nofollow if hostname matches our current host. Thanks 178
113 for reporting, and Neike Taika-Tessaro for helping diagnose.
114 - Do not unset parser variable; this fixes intermittent serialization
115 problems. Thanks Neike Taika-Tessaro for reporting, bill
116 <10010tiger@gmail.com> for diagnosing.
117 - Fix iconv truncation bug, where non-UTF-8 target encodings see
118 output truncated after around 8000 characters. Thanks Jörg Ludwig
119 <joerg.ludwig@iserv.eu> for reporting.
120 - Fix broken table content model for XHTML1.1 (and also earlier
121 versions, although the W3C validator doesn't catch those violations).
122 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
124 4.3.0, released 2011-03-27
125 # Fixed broken caching of customized raw definitions, but requires an
126 API change. The old API still works but will emit a warning,
127 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
128 for how to upgrade your code.
129 # Protect against Internet Explorer innerHTML behavior by specially
130 treating attributes with backticks but no angled brackets, quotes or
131 spaces. This constitutes a slight semantic change, which can be
132 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
134 # Protect against cssText/innerHTML by restricting allowed characters
135 used in fonts further than mandated by the specification and encoding
136 some extra special characters in URLs. Reported by Neike
137 Taika-Tessaro and Mario Heiderich.
138 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
139 ! More types of SPL autoloaders allowed on later versions of PHP.
140 ! Implementations for position, top, left, right, bottom, z-index
141 when %CSS.Trusted is on.
142 ! Add %Cache.SerializerPermissions option for custom serializer
143 directory/file permissions
144 ! Fix longstanding bug in Flash support for non-IE browsers, and
145 allow more wmode attributes.
146 ! Add %CSS.AllowedFonts to restrict permissible font names.
147 - Switch to an iterative traversal of the DOM, which prevents us
148 from running out of stack space for deeply nested documents.
149 Thanks Maxim Krizhanovsky for contributing a patch.
150 - Make removal of conditional IE comments ungreedy; thanks Bernd
152 - Escape CDATA before removing Internet Explorer comments.
153 - Fix removal of id attributes under certain conditions by ensuring
154 armor attributes are preserved when recreating tags.
155 - Check if schema.ser was corrupted.
156 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
157 This safety check is only done for HTMLPurifier.auto.php; if you
158 are using standalone or the specialized includes files, you're
159 expected to know what you're doing.
160 - Stop repeatedly writing the cache file after I'm done customizing a
161 raw definition. Reported by ajh.
162 - Switch to using require_once in the Bootstrap to work around bad
163 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
164 - Fix URI handling when hostname is missing but scheme is present.
165 Reported by Neike Taika-Tessaro.
166 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
168 - Fix harmless notice from indexing into empty string. Thanks Matthijs
169 Kooijman <matthijs@stdin.nl> for reporting.
170 - Don't autoclose no parent elements are able to support the element
171 that triggered the autoclose. In particular fixes strange behavior
172 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
173 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
175 4.2.0, released 2010-09-15
176 ! Added %Core.RemoveProcessingInstructions, which lets you remove
177 <? ... ?> statements.
178 ! Added %URI.DisableResources functionality; the directive originally
179 did nothing. Thanks David Rothstein for reporting.
180 ! Add documentation about configuration directive types.
181 ! Add %CSS.ForbiddenProperties configuration directive.
182 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
183 to utilize full-screen mode.
184 ! Add optional support for the <code>file</code> URI scheme, enable
185 by explicitly setting %URI.AllowedSchemes.
186 ! Add %Core.NormalizeNewlines options to allow turning off newline
188 - Fix improper handling of Internet Explorer conditional comments
189 by parser. Thanks zmonteca for reporting.
190 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
191 Thanks sidepodcast for the fix.
192 - Warn if an element is allowed, but an attribute it requires is
195 4.1.1, released 2010-05-31
196 - Fix undefined index warnings in maintenance scripts.
197 - Fix bug in DirectLex for parsing elements with a single attribute
199 - Rewrite CSS output logic for font-family and url(). Thanks Mario
200 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
201 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
202 - Emit an error for CollectErrors if a body is extracted
203 - Fix bug where in background-position for center keyword handling.
204 - Fix infinite loop when a wrapper element is inserted in a context
205 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
206 - Remove +x bit and shebang from index.php; only supported mode is to
207 explicitly call it with php.
208 - Make test script less chatty when log_errors is on.
210 4.1.0, released 2010-04-26
211 ! Support proprietary height attribute on table element
212 ! Support YouTube slideshows that contain /cp/ in their URL.
213 ! Support for data: URI scheme; not enabled by default, add it using
215 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
216 ! Support for Internet Explorer compatibility with %HTML.SafeObject
217 using %Output.FlashCompat.
218 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
219 - Always quote the insides of url(...) in CSS.
221 4.0.0, released 2009-07-07
222 # APIs for ConfigSchema subsystem have substantially changed. See
223 docs/dev-config-bcbreaks.txt for details; in essence, anything that
224 had both namespace and directive now have a single unified key.
225 # Some configuration directives were renamed, specifically:
226 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
227 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
228 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
229 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
230 As usual, the old directive names will still work, but will throw E_NOTICE
232 # The allowed values for class have been relaxed to allow all of CDATA for
233 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
234 %Attr.ClassUseCDATA to false.
235 # Instead of appending the content model to an old content model, a blank
236 element will replace the old content model. You can use #SUPER to get
237 the old content model.
238 ! More robust support for name="" and id=""
239 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
240 configuration, and have changes to that configuration be propagated
241 to all of its children.
242 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
243 the name attribute when set. Use with care. Thanks Ian Cook for
245 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
246 tags that contain non-breaking spaces as well other whitespace. You
247 can also modify which tags should have maintained with
248 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
249 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
250 classes users can use to a specified finite set of classes, and
251 %Attr.ForbiddenClasses, which is the logical inverse.
252 ! You can now maintain your own configuration schema directories by
253 creating a config-schema.php file or passing an extra argument. Check
254 docs/dev-config-schema.html for more details.
255 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
256 your configuration in a compact serial file, which you can unserialize
257 and use directly without having to go through the overhead of setup.
258 - Fix bug where URIDefinition would not get cleared if it's directives got
260 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
261 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
262 - Make %URI.Munge not apply to links that have the same host as your host.
263 - Prevent stray </body> tag from truncating output, if a second </body>
265 . Created script maintenance/rename-config.php for renaming a configuration
266 directive while maintaining its alias. This script does not change source code.
267 . Implement namespace locking for definition construction, to prevent
268 bugs where a directive is used for definition construction but is not
269 used to construct the cache hash.
271 3.3.0, released 2009-02-16
272 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
273 ! Implement generic property list classess
274 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
275 does not do the "right thing" with characters not supported in the output
277 - Spellcheck UTF-8: The Secret To Character Encoding
278 - Fix improper removal of the contents of elements with only whitespace. Thanks
279 Eric Wald for reporting.
280 - Fix broken test suite in versions of PHP without spl_autoload_register()
281 - Fix degenerate case with YouTube filter involving double hyphens.
282 Thanks Pierre Attar for reporting.
283 - Fix YouTube rendering problem on certain versions of Firefox.
284 - Fix CSSDefinition Printer problems with decorators
285 - Add text parameter to unit tests, forces text output
286 . Add verbose mode to command line test runner, use (--verbose)
287 . Turn on unit tests for UnitConverter
288 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
289 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
291 . Removed trailing whitespace from all text files, see
292 remote-trailing-whitespace.php maintenance script.
293 . Convert configuration to use property list backend.
295 3.2.0, released 2008-10-31
296 # Using %Core.CollectErrors forces line number/column tracking on, whereas
297 previously you could theoretically turn it off.
298 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
299 use handleEnd() instead.
300 ! %Output.AttrSort for when you need your attributes in alphabetical order to
301 deal with a bug in FCKEditor. Requested by frank farmer.
302 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
303 ! Proper support for name attribute. It is now allowed and equivalent to the id
304 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
305 is heavy (for all doctypes).
306 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
307 use on hand-written HTML.
308 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
309 the strategy to be used, standalone, on untrusted input.
310 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
311 processing of left angled brackets in smileys and other whatnot.
312 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
313 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
314 the --only-phpt parameter, although for backwards-compatibility the flag
316 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
317 Users who are not performing inbound filtering, this may seem a little
318 useless, but as a bonus, the test suite and handling of edge cases is also
320 ! Experimental implementation of forms for %HTML.Trusted
321 ! Track column numbers when maintain line numbers is on
322 ! Proprietary 'background' attribute on table-related elements converted into
323 corresponding CSS. Thanks Fusemail for sponsoring this feature!
324 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
326 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
327 time of operation varies slightly from notifyEnd() as *all* end tokens are
328 processed by the injector before they are subject to the well-formedness rules.
329 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
330 basename of image when not present.
331 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
332 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
333 the other involving an undefined $is_folder error.
334 - Throw error when %Core.Encoding is set to a spurious value. Previously,
335 this errored silently and returned false.
336 - Redirected stderr to stdout for flush error output.
337 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
339 - Do not re-munge URL if the output URL has the same host as the input URL.
341 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
342 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
343 - Fix bug with inline elements in blockquotes conflicting with strict doctype
344 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
345 - Fix bug where dots and double-dots in absolute URLs without hostname were
346 not collapsed by URIFilter_MakeAbsolute.
347 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
348 by reordering their addition.
349 - Will now throw exception on many error conditions during lexer creation; also
350 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
352 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
353 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
354 Reported by David Morton.
355 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
356 for more interesting filter-backtracking
357 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
358 index to reprocess tokens.
359 . StringHashParser now allows for multiline sections with "empty" content;
360 previously the section would remain undefined.
361 . Added --quick option to multitest.php, which tests only the most recent
362 release for each series.
363 . Added --distro option to multitest.php, which accepts either 'normal' or
364 'standalone'. This supercedes --exclude-normal and --exclude-standalone
366 3.1.1, released 2008-06-19
367 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
368 In order to enable this again, please set %URI.MungeResources to true.
369 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
370 and height/width HTML with %HTML.MaxImgLength.
371 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
372 for sponsoring this feature. Check out the corresponding documentation
373 for details. (Att Nightly testers: The API for this feature changed before
374 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
375 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
376 ! Implemented post URI filtering. Set member variable $post to true to set
378 ! Allow modules to define injectors via $info_injector. Injectors are
379 automatically disabled if injector's needed elements are not found.
380 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
381 Thanks Chris for sponsoring. If you've been using ad hoc code from the
382 forums, PLEASE use this instead.
383 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
384 embedded, tag name, attribute name, CSS property name). See %URI.Munge
385 for more details. Requested by Jochem Blok.
386 - Disable percent height/width attributes for img.
387 - AttrValidator operations are now atomic; updates to attributes are not
388 manifest in token until end of operations. This prevents naughty internal
389 code from directly modifying CurrentToken when they're not supposed to.
390 This semantics change was requested by frank farmer.
391 - Percent encoding checks enabled for URI query and fragment
392 - Fix stray backslashes in font-family; CSS Unicode character escapes are
393 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
395 - Improve parseCDATA algorithm to take into account newline normalization
396 - Account for browser confusion between Yen character and backslash in
397 Shift_JIS encoding. This fix generalizes to any other encoding which is not
398 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
399 - Fix missing configuration parameter in Generator calls. Thanks vs for the
401 - Improved adherence to Unicode by checking for non-character codepoints.
402 Thanks Geoffrey Sneddon for reporting. This may result in degraded
403 performance for extremely large inputs.
404 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
406 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
407 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
409 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
410 to __construct($min, $max). __construct(true) is equivalent to
412 . Added HTMLPurifier_AttrDef_Switch class
413 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
414 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
415 get this called with the configuration object. All modules now
416 use this rather than __construct(), although legacy code using constructors
417 will still work--the new format, however, lets modules access the
418 configuration object for HTML namespace dependant tweaks.
419 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
420 . ConfigSchema data-structure heavily optimized; on average it uses a third
421 the memory it did previously. The interface has changed accordingly,
422 consult changes to HTMLPurifier_Config for details.
423 . Variable parsing types now are magic integers instead of strings
424 . Added benchmark for ConfigSchema
425 . HTMLPurifier_Generator requires $config and $context parameters. If you
426 don't know what they should be, use HTMLPurifier_Config::createDefault()
427 and new HTMLPurifier_Context().
428 . Printers now properly distinguish between output configuration, and
429 target configuration. This is not applicable to scripts using
430 the Printers for HTML Purifier related tasks.
431 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
432 fatal errors will ensue.
433 . URIFilter->prepare can return false in order to abort loading of the filter
434 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
435 an external resource.
436 . %URI.Munge functionality factored out into a post-filter class.
437 . Added CurrentCSSProperty context variable during CSS validation
439 3.1.0, released 2008-05-18
440 # Unnecessary references to objects (vestiges of PHP4) removed from method
441 signatures. The following methods do not need references when assigning from
442 them and will result in E_STRICT errors if you try:
443 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
444 + HTMLPurifier_ConfigSchema::instance()
445 + HTMLPurifier_DefinitionCacheFactory::instance()
446 + HTMLPurifier_DefinitionCacheFactory->create()
447 + HTMLPurifier_DoctypeRegistry->register()
448 + HTMLPurifier_DoctypeRegistry->get()
449 + HTMLPurifier_HTMLModule->addElement()
450 + HTMLPurifier_HTMLModule->addBlankElement()
451 + HTMLPurifier_LanguageFactory::instance()
452 # Printer_ConfigForm's get*() functions were static-ified
453 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
454 form of tag@attr, NOT tag.attr (which will throw an error and won't do
455 anything). This is for forwards compatibility with XML; you'd do best
456 to migrate an %HTML.AllowedAttributes directives to this syntax too.
457 ! Allow index to be false for config from form creation
458 ! Added HTMLPurifier::VERSION constant
459 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
460 and allows for version numbers like "3.1.0-dev".
461 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
462 ! HTML Purifier's URI handling is a lot more robust, with much stricter
463 validation checks and better percent encoding handling. Thanks Gareth Heyes
464 for indicating security vulnerabilities from lax percent encoding.
465 ! Bootstrap autoloader deals more robustly with classes that don't exist,
466 preventing class_exists($class, true) from barfing.
467 - InterchangeBuilder now alphabetizes its lists
468 - Validation error in configdoc output fixed
469 - Iconv and other encoding errors muted even with custom error handlers that
470 do not honor error_reporting
471 - Add protection against imagecrash attack with CSS height/width
472 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
473 - Fixed and revamped broken ConfigForm smoketest
474 - Bug with bool/null fields in Printer_ConfigForm fixed
475 - Bug with global forbidden attributes fixed
476 - Improved error messages for allowed and forbidden HTML elements and attributes

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

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

665 require_once 'HTMLPurifier/Lexer/PH5P.php';
666 $config->set('Core', 'LexerImpl', 'PH5P');
667 Note that this Lexer introduces some classes not in the HTMLPurifier
668 namespace. Also, this is PHP5 only.
669 ! CSS property border-spacing implemented
670 - Fix non-visible parsing error in DirectLex with empty tags that have
671 slashes inside attribute values.
672 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
673 accepted as valid CSS. Usually non-visible, because this styling is the
674 default for tables in most browsers. Thanks Brett Zamir for pointing
676 - Fix validation errors in configuration form
677 - Hammer out a bunch of edge-case bugs in the standalone distribution
678 - Inclusion reflection removed from URISchemeRegistry; you must manually

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

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

755 linkify your HTML input by setting %AutoFormat.AutoParagraph and
756 %AutoFormat.Linkify to true
757 ! Newlines normalized internally, and then converted back to the
758 value of PHP_EOL. If this is not desired, set your newline format
759 using %Output.Newline.
760 ! Beta error collection, messages are implemented for the most generic
761 cases involving Lexing or Strategies
762 - Clean up special case code for <script> tags

798 # Transform modules changed to Tidy modules, which offer more flexibility
799 and better modularization

801 performed on it, ensuring that its internal state stays consistent.
802 To revert this behavior, you can set the $autoFinalize member variable
803 off, but it's not recommended.
804 # New compact syntax for AttrDef objects that can be used to instantiate
805 new objects via make()
806 # Definitions (esp. HTMLDefinition) are now cached for a significant
807 performance boost. You can disable caching by setting %Core.DefinitionCache
