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.
18 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
21 4.7.0, released 2015-08-04
22 # opacity is now considered a "tricky" CSS property rather than a
24 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
25 an element should be considered "empty" (maybe preserve if it
26 has attributes), and modify iframe support so that the iframe
27 is removed if it is missing a src attribute. Thanks meeva for
29 - Don't truncate upon encountering </div> when using DOMLex. Thanks
30 Myrto Christina for finally convincing me to fix this.
31 - Update YouTube filter for new code.
32 - Fix parsing of rgb() values with spaces in them for 'border'
34 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
37 4.6.0, released 2013-11-30
38 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
39 Please update any verification scripts you may have.
40 # URI parsing algorithm was made more strict, so only prefixes which
41 looks like schemes will actually be schemes. Thanks
42 Michael Gusev <mgusev@sugarcrm.com> for fixing.
43 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
45 ! New directive %Core.AllowHostnameUnderscore which allows underscores
47 - Eliminate quadratic behavior in DOMLex by using a proper queue.
48 Thanks Ole Laursen for noticing this.
49 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
50 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
51 Networks for sponsoring this work.
52 - Made Linkify URL parser a bit less permissive, so that non-breaking
53 spaces and commas are not included as part of URL. Thanks nAS for fixing.
54 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
55 David Hirtz for reporting.
56 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
59 4.5.0, released 2013-02-17
60 # Fix bug where stacked attribute transforms clobber each other;
61 this also means it's no longer possible to override attribute
62 transforms in later modules. No internal code was using this
63 but this may break some clients.
64 # We now use SHA-1 to identify cached definitions, instead of MD5.
65 ! Support display:inline-block
66 ! Support for more white-space CSS values.
67 ! Permit underscores in font families
68 ! Support for page-break-* CSS3 properties when proprietary properties
70 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
71 SGML excludes checking. If HTML Purifier is removing too much text
72 and you don't care about full standards compliance, try setting this to
74 - Use prepend for SPL autoloading on PHP 5.3 and later.
75 - Fix bug with nofollow transform when pre-existing rel exists.
76 - Fix bug where background:url() always gets lower-cased
77 (but not background-image:url())
78 - Fix bug with non lower-case color names in HTML
79 - Fix bug where data URI validation doesn't remove temporary files.
80 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
81 - Don't remove certain empty tags on RemoveEmpty.
83 4.4.0, released 2012-01-18
84 # Removed PEARSax3 handler.
85 # URI.Munge now munges URIs inside the same host that go from https
86 to http. Reported by Neike Taika-Tessaro.
87 # Core.EscapeNonASCIICharacters now always transforms entities to
88 entities, even if target encoding is UTF-8.
89 # Tighten up selector validation in ExtractStyleBlocks.
90 Non-syntactically valid selectors are now rejected, along with
91 some of the more obscure ones such as attribute selectors, the
92 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
93 ID and class selectors now work properly with the relevant
94 configuration attributes. Also, mute errors when parsing CSS
95 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
96 ! Added support for 'scope' attribute on tables.
97 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
98 ! Properly handle sub-lists directly nested inside of lists in
99 a standards compliant way, by moving them into the preceding <li>
100 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
101 limited allowed comments in untrusted situations.
102 ! Implement iframes, and allow them to be used in untrusted mode with
103 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
104 <brad.froehle@gmail.com> for submitting an initial version of the patch.
105 ! The Forms module now works properly for transitional doctypes.
106 ! Added support for internationalized domain names. You need the PEAR
107 Net_IDNA2 module to be in your path; if it is installed, ensure the
108 class can be loaded and then set %Core.EnableIDNA to true.
109 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
110 <yramirez-htmlpurifier@adicio.com> for reporting.
111 - Explicitly initialize anonModule variable to null.
112 - Do not duplicate nofollow if already present. Thanks 178
114 - Do not add nofollow if hostname matches our current host. Thanks 178
115 for reporting, and Neike Taika-Tessaro for helping diagnose.
116 - Do not unset parser variable; this fixes intermittent serialization
117 problems. Thanks Neike Taika-Tessaro for reporting, bill
118 <10010tiger@gmail.com> for diagnosing.
119 - Fix iconv truncation bug, where non-UTF-8 target encodings see
120 output truncated after around 8000 characters. Thanks Jörg Ludwig
121 <joerg.ludwig@iserv.eu> for reporting.
122 - Fix broken table content model for XHTML1.1 (and also earlier
123 versions, although the W3C validator doesn't catch those violations).
124 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
126 4.3.0, released 2011-03-27
127 # Fixed broken caching of customized raw definitions, but requires an
128 API change. The old API still works but will emit a warning,
129 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
130 for how to upgrade your code.
131 # Protect against Internet Explorer innerHTML behavior by specially
132 treating attributes with backticks but no angled brackets, quotes or
133 spaces. This constitutes a slight semantic change, which can be
134 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
136 # Protect against cssText/innerHTML by restricting allowed characters
137 used in fonts further than mandated by the specification and encoding
138 some extra special characters in URLs. Reported by Neike
139 Taika-Tessaro and Mario Heiderich.
140 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
141 ! More types of SPL autoloaders allowed on later versions of PHP.
142 ! Implementations for position, top, left, right, bottom, z-index
143 when %CSS.Trusted is on.
144 ! Add %Cache.SerializerPermissions option for custom serializer
145 directory/file permissions
146 ! Fix longstanding bug in Flash support for non-IE browsers, and
147 allow more wmode attributes.
148 ! Add %CSS.AllowedFonts to restrict permissible font names.
149 - Switch to an iterative traversal of the DOM, which prevents us
150 from running out of stack space for deeply nested documents.
151 Thanks Maxim Krizhanovsky for contributing a patch.
152 - Make removal of conditional IE comments ungreedy; thanks Bernd
154 - Escape CDATA before removing Internet Explorer comments.
155 - Fix removal of id attributes under certain conditions by ensuring
156 armor attributes are preserved when recreating tags.
157 - Check if schema.ser was corrupted.
158 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
159 This safety check is only done for HTMLPurifier.auto.php; if you
160 are using standalone or the specialized includes files, you're
161 expected to know what you're doing.
162 - Stop repeatedly writing the cache file after I'm done customizing a
163 raw definition. Reported by ajh.
164 - Switch to using require_once in the Bootstrap to work around bad
165 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
166 - Fix URI handling when hostname is missing but scheme is present.
167 Reported by Neike Taika-Tessaro.
168 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
170 - Fix harmless notice from indexing into empty string. Thanks Matthijs
171 Kooijman <matthijs@stdin.nl> for reporting.
172 - Don't autoclose no parent elements are able to support the element
173 that triggered the autoclose. In particular fixes strange behavior
174 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
175 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
177 4.2.0, released 2010-09-15
178 ! Added %Core.RemoveProcessingInstructions, which lets you remove
179 <? ... ?> statements.
180 ! Added %URI.DisableResources functionality; the directive originally
181 did nothing. Thanks David Rothstein for reporting.
182 ! Add documentation about configuration directive types.
183 ! Add %CSS.ForbiddenProperties configuration directive.
184 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
185 to utilize full-screen mode.
186 ! Add optional support for the <code>file</code> URI scheme, enable
187 by explicitly setting %URI.AllowedSchemes.
188 ! Add %Core.NormalizeNewlines options to allow turning off newline
190 - Fix improper handling of Internet Explorer conditional comments
191 by parser. Thanks zmonteca for reporting.
192 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
193 Thanks sidepodcast for the fix.
194 - Warn if an element is allowed, but an attribute it requires is
197 4.1.1, released 2010-05-31
198 - Fix undefined index warnings in maintenance scripts.
199 - Fix bug in DirectLex for parsing elements with a single attribute
201 - Rewrite CSS output logic for font-family and url(). Thanks Mario
202 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
203 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
204 - Emit an error for CollectErrors if a body is extracted
205 - Fix bug where in background-position for center keyword handling.
206 - Fix infinite loop when a wrapper element is inserted in a context
207 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
208 - Remove +x bit and shebang from index.php; only supported mode is to
209 explicitly call it with php.
210 - Make test script less chatty when log_errors is on.
212 4.1.0, released 2010-04-26
213 ! Support proprietary height attribute on table element
214 ! Support YouTube slideshows that contain /cp/ in their URL.
215 ! Support for data: URI scheme; not enabled by default, add it using
217 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
218 ! Support for Internet Explorer compatibility with %HTML.SafeObject
219 using %Output.FlashCompat.
220 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
221 - Always quote the insides of url(...) in CSS.
223 4.0.0, released 2009-07-07
224 # APIs for ConfigSchema subsystem have substantially changed. See
225 docs/dev-config-bcbreaks.txt for details; in essence, anything that
226 had both namespace and directive now have a single unified key.
227 # Some configuration directives were renamed, specifically:
228 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
229 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
230 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
231 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
232 As usual, the old directive names will still work, but will throw E_NOTICE
234 # The allowed values for class have been relaxed to allow all of CDATA for
235 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
236 %Attr.ClassUseCDATA to false.
237 # Instead of appending the content model to an old content model, a blank
238 element will replace the old content model. You can use #SUPER to get
239 the old content model.
240 ! More robust support for name="" and id=""
241 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
242 configuration, and have changes to that configuration be propagated
243 to all of its children.
244 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
245 the name attribute when set. Use with care. Thanks Ian Cook for
247 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
248 tags that contain non-breaking spaces as well other whitespace. You
249 can also modify which tags should have maintained with
250 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
251 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
252 classes users can use to a specified finite set of classes, and
253 %Attr.ForbiddenClasses, which is the logical inverse.
254 ! You can now maintain your own configuration schema directories by
255 creating a config-schema.php file or passing an extra argument. Check
256 docs/dev-config-schema.html for more details.
257 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
258 your configuration in a compact serial file, which you can unserialize
259 and use directly without having to go through the overhead of setup.
260 - Fix bug where URIDefinition would not get cleared if it's directives got
262 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
263 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
264 - Make %URI.Munge not apply to links that have the same host as your host.
265 - Prevent stray </body> tag from truncating output, if a second </body>
267 . Created script maintenance/rename-config.php for renaming a configuration
268 directive while maintaining its alias. This script does not change source code.
269 . Implement namespace locking for definition construction, to prevent
270 bugs where a directive is used for definition construction but is not
271 used to construct the cache hash.
273 3.3.0, released 2009-02-16
274 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
275 ! Implement generic property list classess
276 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
277 does not do the "right thing" with characters not supported in the output
279 - Spellcheck UTF-8: The Secret To Character Encoding
280 - Fix improper removal of the contents of elements with only whitespace. Thanks
281 Eric Wald for reporting.
282 - Fix broken test suite in versions of PHP without spl_autoload_register()
283 - Fix degenerate case with YouTube filter involving double hyphens.
284 Thanks Pierre Attar for reporting.
285 - Fix YouTube rendering problem on certain versions of Firefox.
286 - Fix CSSDefinition Printer problems with decorators
287 - Add text parameter to unit tests, forces text output
288 . Add verbose mode to command line test runner, use (--verbose)
289 . Turn on unit tests for UnitConverter
290 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
291 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
293 . Removed trailing whitespace from all text files, see
294 remote-trailing-whitespace.php maintenance script.
295 . Convert configuration to use property list backend.
297 3.2.0, released 2008-10-31
298 # Using %Core.CollectErrors forces line number/column tracking on, whereas
299 previously you could theoretically turn it off.
300 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
301 use handleEnd() instead.
302 ! %Output.AttrSort for when you need your attributes in alphabetical order to
303 deal with a bug in FCKEditor. Requested by frank farmer.
304 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
305 ! Proper support for name attribute. It is now allowed and equivalent to the id
306 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
307 is heavy (for all doctypes).
308 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
309 use on hand-written HTML.
310 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
311 the strategy to be used, standalone, on untrusted input.
312 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
313 processing of left angled brackets in smileys and other whatnot.
314 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
315 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
316 the --only-phpt parameter, although for backwards-compatibility the flag
318 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
319 Users who are not performing inbound filtering, this may seem a little
320 useless, but as a bonus, the test suite and handling of edge cases is also
322 ! Experimental implementation of forms for %HTML.Trusted
323 ! Track column numbers when maintain line numbers is on
324 ! Proprietary 'background' attribute on table-related elements converted into
325 corresponding CSS. Thanks Fusemail for sponsoring this feature!
326 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
328 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
329 time of operation varies slightly from notifyEnd() as *all* end tokens are
330 processed by the injector before they are subject to the well-formedness rules.
331 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
332 basename of image when not present.
333 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
334 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
335 the other involving an undefined $is_folder error.
336 - Throw error when %Core.Encoding is set to a spurious value. Previously,
337 this errored silently and returned false.
338 - Redirected stderr to stdout for flush error output.
339 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
341 - Do not re-munge URL if the output URL has the same host as the input URL.
343 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
344 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
345 - Fix bug with inline elements in blockquotes conflicting with strict doctype
346 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
347 - Fix bug where dots and double-dots in absolute URLs without hostname were
348 not collapsed by URIFilter_MakeAbsolute.
349 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
350 by reordering their addition.
351 - Will now throw exception on many error conditions during lexer creation; also
352 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
354 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
355 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
356 Reported by David Morton.
357 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
358 for more interesting filter-backtracking
359 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
360 index to reprocess tokens.
361 . StringHashParser now allows for multiline sections with "empty" content;
362 previously the section would remain undefined.
363 . Added --quick option to multitest.php, which tests only the most recent
364 release for each series.
365 . Added --distro option to multitest.php, which accepts either 'normal' or
366 'standalone'. This supercedes --exclude-normal and --exclude-standalone
368 3.1.1, released 2008-06-19
369 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
370 In order to enable this again, please set %URI.MungeResources to true.
371 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
372 and height/width HTML with %HTML.MaxImgLength.
373 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
374 for sponsoring this feature. Check out the corresponding documentation
375 for details. (Att Nightly testers: The API for this feature changed before
376 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
377 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
378 ! Implemented post URI filtering. Set member variable $post to true to set
380 ! Allow modules to define injectors via $info_injector. Injectors are
381 automatically disabled if injector's needed elements are not found.
382 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
383 Thanks Chris for sponsoring. If you've been using ad hoc code from the
384 forums, PLEASE use this instead.
385 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
386 embedded, tag name, attribute name, CSS property name). See %URI.Munge
387 for more details. Requested by Jochem Blok.
388 - Disable percent height/width attributes for img.
389 - AttrValidator operations are now atomic; updates to attributes are not
390 manifest in token until end of operations. This prevents naughty internal
391 code from directly modifying CurrentToken when they're not supposed to.
392 This semantics change was requested by frank farmer.
393 - Percent encoding checks enabled for URI query and fragment
394 - Fix stray backslashes in font-family; CSS Unicode character escapes are
395 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
397 - Improve parseCDATA algorithm to take into account newline normalization
398 - Account for browser confusion between Yen character and backslash in
399 Shift_JIS encoding. This fix generalizes to any other encoding which is not
400 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
401 - Fix missing configuration parameter in Generator calls. Thanks vs for the
403 - Improved adherence to Unicode by checking for non-character codepoints.
404 Thanks Geoffrey Sneddon for reporting. This may result in degraded
405 performance for extremely large inputs.
406 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
408 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
409 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
411 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
412 to __construct($min, $max). __construct(true) is equivalent to
414 . Added HTMLPurifier_AttrDef_Switch class
415 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
416 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
417 get this called with the configuration object. All modules now
418 use this rather than __construct(), although legacy code using constructors
419 will still work--the new format, however, lets modules access the
420 configuration object for HTML namespace dependant tweaks.
421 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
422 . ConfigSchema data-structure heavily optimized; on average it uses a third
423 the memory it did previously. The interface has changed accordingly,
424 consult changes to HTMLPurifier_Config for details.
425 . Variable parsing types now are magic integers instead of strings
426 . Added benchmark for ConfigSchema
427 . HTMLPurifier_Generator requires $config and $context parameters. If you
428 don't know what they should be, use HTMLPurifier_Config::createDefault()
429 and new HTMLPurifier_Context().
430 . Printers now properly distinguish between output configuration, and
431 target configuration. This is not applicable to scripts using
432 the Printers for HTML Purifier related tasks.
433 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
434 fatal errors will ensue.
435 . URIFilter->prepare can return false in order to abort loading of the filter
436 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
437 an external resource.
438 . %URI.Munge functionality factored out into a post-filter class.
439 . Added CurrentCSSProperty context variable during CSS validation
441 3.1.0, released 2008-05-18
442 # Unnecessary references to objects (vestiges of PHP4) removed from method
443 signatures. The following methods do not need references when assigning from
444 them and will result in E_STRICT errors if you try:
445 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
446 + HTMLPurifier_ConfigSchema::instance()
447 + HTMLPurifier_DefinitionCacheFactory::instance()
448 + HTMLPurifier_DefinitionCacheFactory->create()
449 + HTMLPurifier_DoctypeRegistry->register()
450 + HTMLPurifier_DoctypeRegistry->get()
451 + HTMLPurifier_HTMLModule->addElement()
452 + HTMLPurifier_HTMLModule->addBlankElement()
453 + HTMLPurifier_LanguageFactory::instance()
454 # Printer_ConfigForm's get*() functions were static-ified
455 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
456 form of tag@attr, NOT tag.attr (which will throw an error and won't do
457 anything). This is for forwards compatibility with XML; you'd do best
458 to migrate an %HTML.AllowedAttributes directives to this syntax too.
459 ! Allow index to be false for config from form creation
460 ! Added HTMLPurifier::VERSION constant
461 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
462 and allows for version numbers like "3.1.0-dev".
463 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
464 ! HTML Purifier's URI handling is a lot more robust, with much stricter
465 validation checks and better percent encoding handling. Thanks Gareth Heyes
466 for indicating security vulnerabilities from lax percent encoding.
467 ! Bootstrap autoloader deals more robustly with classes that don't exist,
468 preventing class_exists($class, true) from barfing.
469 - InterchangeBuilder now alphabetizes its lists
470 - Validation error in configdoc output fixed
471 - Iconv and other encoding errors muted even with custom error handlers that
472 do not honor error_reporting
473 - Add protection against imagecrash attack with CSS height/width
474 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
475 - Fixed and revamped broken ConfigForm smoketest
476 - Bug with bool/null fields in Printer_ConfigForm fixed
477 - Bug with global forbidden attributes fixed

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

644 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
645 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
646 to better communicate its purpose
647 . Error unit tests can now specify the expectation of no errors. Future
648 iterations of the harness will be extremely strict about what errors

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

702 ! Phorum mod implemented for HTML Purifier
703 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
704 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary

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

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

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

800 # Transform modules changed to Tidy modules, which offer more flexibility
801 and better modularization
802 # Configuration object now finalizes itself when a read operation is
803 performed on it, ensuring that its internal state stays consistent.
804 To revert this behavior, you can set the $autoFinalize member variable
805 off, but it's not recommended.
806 # New compact syntax for AttrDef objects that can be used to instantiate
807 new objects via make()
808 # Definitions (esp. HTMLDefinition) are now cached for a significant
809 performance boost. You can disable caching by setting %Core.DefinitionCache
