4 = KEY ====================
10 ==========================
12 4.8.0, unknown release date
13 ! Full PHP 7 compatibility, the test suite is ALL GO.
14 ! %CSS.AllowDuplicates permits duplicate CSS properties.
15 - alt truncation could result in malformed UTF-8 sequence. Don't
16 truncate. Thanks Brandon Farber for reporting.
17 - Linkify regex is smarter, based off of Gruber's regex.
18 - IDNA supported natively on PHP 5.3 and later.
19 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
21 - Minor bounds error fix to squash a PHP 7 notice.
22 - Support non-/tmp temporary directories for data:// validation
23 - Give a better error message when a user attempts to allow
24 ul/ol without allowing li.
25 - On some versions of PHP, the Serializer DefinitionCache could
26 infinite loop when the directory exists but is not listable. (#49)
28 4.7.0, released 2015-08-04
29 # opacity is now considered a "tricky" CSS property rather than a
31 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
32 an element should be considered "empty" (maybe preserve if it
33 has attributes), and modify iframe support so that the iframe
34 is removed if it is missing a src attribute. Thanks meeva for
36 - Don't truncate upon encountering </div> when using DOMLex. Thanks
37 Myrto Christina for finally convincing me to fix this.
38 - Update YouTube filter for new code.
39 - Fix parsing of rgb() values with spaces in them for 'border'
41 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
44 4.6.0, released 2013-11-30
45 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
46 Please update any verification scripts you may have.
47 # URI parsing algorithm was made more strict, so only prefixes which
48 looks like schemes will actually be schemes. Thanks
49 Michael Gusev <mgusev@sugarcrm.com> for fixing.
50 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
52 ! New directive %Core.AllowHostnameUnderscore which allows underscores
54 - Eliminate quadratic behavior in DOMLex by using a proper queue.
55 Thanks Ole Laursen for noticing this.
56 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
57 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
58 Networks for sponsoring this work.
59 - Made Linkify URL parser a bit less permissive, so that non-breaking
60 spaces and commas are not included as part of URL. Thanks nAS for fixing.
61 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
62 David Hirtz for reporting.
63 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
66 4.5.0, released 2013-02-17
67 # Fix bug where stacked attribute transforms clobber each other;
68 this also means it's no longer possible to override attribute
69 transforms in later modules. No internal code was using this
70 but this may break some clients.
71 # We now use SHA-1 to identify cached definitions, instead of MD5.
72 ! Support display:inline-block
73 ! Support for more white-space CSS values.
74 ! Permit underscores in font families
75 ! Support for page-break-* CSS3 properties when proprietary properties
77 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
78 SGML excludes checking. If HTML Purifier is removing too much text
79 and you don't care about full standards compliance, try setting this to
81 - Use prepend for SPL autoloading on PHP 5.3 and later.
82 - Fix bug with nofollow transform when pre-existing rel exists.
83 - Fix bug where background:url() always gets lower-cased
84 (but not background-image:url())
85 - Fix bug with non lower-case color names in HTML
86 - Fix bug where data URI validation doesn't remove temporary files.
87 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
88 - Don't remove certain empty tags on RemoveEmpty.
90 4.4.0, released 2012-01-18
91 # Removed PEARSax3 handler.
92 # URI.Munge now munges URIs inside the same host that go from https
93 to http. Reported by Neike Taika-Tessaro.
94 # Core.EscapeNonASCIICharacters now always transforms entities to
95 entities, even if target encoding is UTF-8.
96 # Tighten up selector validation in ExtractStyleBlocks.
97 Non-syntactically valid selectors are now rejected, along with
98 some of the more obscure ones such as attribute selectors, the
99 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
100 ID and class selectors now work properly with the relevant
101 configuration attributes. Also, mute errors when parsing CSS
102 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
103 ! Added support for 'scope' attribute on tables.
104 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
105 ! Properly handle sub-lists directly nested inside of lists in
106 a standards compliant way, by moving them into the preceding <li>
107 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
108 limited allowed comments in untrusted situations.
109 ! Implement iframes, and allow them to be used in untrusted mode with
110 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
111 <brad.froehle@gmail.com> for submitting an initial version of the patch.
112 ! The Forms module now works properly for transitional doctypes.
113 ! Added support for internationalized domain names. You need the PEAR
114 Net_IDNA2 module to be in your path; if it is installed, ensure the
115 class can be loaded and then set %Core.EnableIDNA to true.
116 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
117 <yramirez-htmlpurifier@adicio.com> for reporting.
118 - Explicitly initialize anonModule variable to null.
119 - Do not duplicate nofollow if already present. Thanks 178
121 - Do not add nofollow if hostname matches our current host. Thanks 178
122 for reporting, and Neike Taika-Tessaro for helping diagnose.
123 - Do not unset parser variable; this fixes intermittent serialization
124 problems. Thanks Neike Taika-Tessaro for reporting, bill
125 <10010tiger@gmail.com> for diagnosing.
126 - Fix iconv truncation bug, where non-UTF-8 target encodings see
127 output truncated after around 8000 characters. Thanks Jörg Ludwig
128 <joerg.ludwig@iserv.eu> for reporting.
129 - Fix broken table content model for XHTML1.1 (and also earlier
130 versions, although the W3C validator doesn't catch those violations).
131 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
133 4.3.0, released 2011-03-27
134 # Fixed broken caching of customized raw definitions, but requires an
135 API change. The old API still works but will emit a warning,
136 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
137 for how to upgrade your code.
138 # Protect against Internet Explorer innerHTML behavior by specially
139 treating attributes with backticks but no angled brackets, quotes or
140 spaces. This constitutes a slight semantic change, which can be
141 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
143 # Protect against cssText/innerHTML by restricting allowed characters
144 used in fonts further than mandated by the specification and encoding
145 some extra special characters in URLs. Reported by Neike
146 Taika-Tessaro and Mario Heiderich.
147 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
148 ! More types of SPL autoloaders allowed on later versions of PHP.
149 ! Implementations for position, top, left, right, bottom, z-index
150 when %CSS.Trusted is on.
151 ! Add %Cache.SerializerPermissions option for custom serializer
152 directory/file permissions
153 ! Fix longstanding bug in Flash support for non-IE browsers, and
154 allow more wmode attributes.
155 ! Add %CSS.AllowedFonts to restrict permissible font names.
156 - Switch to an iterative traversal of the DOM, which prevents us
157 from running out of stack space for deeply nested documents.
158 Thanks Maxim Krizhanovsky for contributing a patch.
159 - Make removal of conditional IE comments ungreedy; thanks Bernd
161 - Escape CDATA before removing Internet Explorer comments.
162 - Fix removal of id attributes under certain conditions by ensuring
163 armor attributes are preserved when recreating tags.
164 - Check if schema.ser was corrupted.
165 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
166 This safety check is only done for HTMLPurifier.auto.php; if you
167 are using standalone or the specialized includes files, you're
168 expected to know what you're doing.
169 - Stop repeatedly writing the cache file after I'm done customizing a
170 raw definition. Reported by ajh.
171 - Switch to using require_once in the Bootstrap to work around bad
172 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
173 - Fix URI handling when hostname is missing but scheme is present.
174 Reported by Neike Taika-Tessaro.
175 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
177 - Fix harmless notice from indexing into empty string. Thanks Matthijs
178 Kooijman <matthijs@stdin.nl> for reporting.
179 - Don't autoclose no parent elements are able to support the element
180 that triggered the autoclose. In particular fixes strange behavior
181 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
182 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
184 4.2.0, released 2010-09-15
185 ! Added %Core.RemoveProcessingInstructions, which lets you remove
186 <? ... ?> statements.
187 ! Added %URI.DisableResources functionality; the directive originally
188 did nothing. Thanks David Rothstein for reporting.
189 ! Add documentation about configuration directive types.
190 ! Add %CSS.ForbiddenProperties configuration directive.
191 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
192 to utilize full-screen mode.
193 ! Add optional support for the <code>file</code> URI scheme, enable
194 by explicitly setting %URI.AllowedSchemes.
195 ! Add %Core.NormalizeNewlines options to allow turning off newline
197 - Fix improper handling of Internet Explorer conditional comments
198 by parser. Thanks zmonteca for reporting.
199 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
200 Thanks sidepodcast for the fix.
201 - Warn if an element is allowed, but an attribute it requires is
204 4.1.1, released 2010-05-31
205 - Fix undefined index warnings in maintenance scripts.
206 - Fix bug in DirectLex for parsing elements with a single attribute
208 - Rewrite CSS output logic for font-family and url(). Thanks Mario
209 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
210 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
211 - Emit an error for CollectErrors if a body is extracted
212 - Fix bug where in background-position for center keyword handling.
213 - Fix infinite loop when a wrapper element is inserted in a context
214 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
215 - Remove +x bit and shebang from index.php; only supported mode is to
216 explicitly call it with php.
217 - Make test script less chatty when log_errors is on.
219 4.1.0, released 2010-04-26
220 ! Support proprietary height attribute on table element
221 ! Support YouTube slideshows that contain /cp/ in their URL.
222 ! Support for data: URI scheme; not enabled by default, add it using
224 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
225 ! Support for Internet Explorer compatibility with %HTML.SafeObject
226 using %Output.FlashCompat.
227 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
228 - Always quote the insides of url(...) in CSS.
230 4.0.0, released 2009-07-07
231 # APIs for ConfigSchema subsystem have substantially changed. See
232 docs/dev-config-bcbreaks.txt for details; in essence, anything that
233 had both namespace and directive now have a single unified key.
234 # Some configuration directives were renamed, specifically:
235 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
236 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
237 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
238 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
239 As usual, the old directive names will still work, but will throw E_NOTICE
241 # The allowed values for class have been relaxed to allow all of CDATA for
242 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
243 %Attr.ClassUseCDATA to false.
244 # Instead of appending the content model to an old content model, a blank
245 element will replace the old content model. You can use #SUPER to get
246 the old content model.
247 ! More robust support for name="" and id=""
248 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
249 configuration, and have changes to that configuration be propagated
250 to all of its children.
251 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
252 the name attribute when set. Use with care. Thanks Ian Cook for
254 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
255 tags that contain non-breaking spaces as well other whitespace. You
256 can also modify which tags should have maintained with
257 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
258 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
259 classes users can use to a specified finite set of classes, and
260 %Attr.ForbiddenClasses, which is the logical inverse.
261 ! You can now maintain your own configuration schema directories by
262 creating a config-schema.php file or passing an extra argument. Check
263 docs/dev-config-schema.html for more details.
264 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
265 your configuration in a compact serial file, which you can unserialize
266 and use directly without having to go through the overhead of setup.
267 - Fix bug where URIDefinition would not get cleared if it's directives got
269 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
270 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
271 - Make %URI.Munge not apply to links that have the same host as your host.
272 - Prevent stray </body> tag from truncating output, if a second </body>
274 . Created script maintenance/rename-config.php for renaming a configuration
275 directive while maintaining its alias. This script does not change source code.
276 . Implement namespace locking for definition construction, to prevent
277 bugs where a directive is used for definition construction but is not
278 used to construct the cache hash.
280 3.3.0, released 2009-02-16
281 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
282 ! Implement generic property list classess
283 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
284 does not do the "right thing" with characters not supported in the output
286 - Spellcheck UTF-8: The Secret To Character Encoding
287 - Fix improper removal of the contents of elements with only whitespace. Thanks
288 Eric Wald for reporting.
289 - Fix broken test suite in versions of PHP without spl_autoload_register()
290 - Fix degenerate case with YouTube filter involving double hyphens.
291 Thanks Pierre Attar for reporting.
292 - Fix YouTube rendering problem on certain versions of Firefox.
293 - Fix CSSDefinition Printer problems with decorators
294 - Add text parameter to unit tests, forces text output
295 . Add verbose mode to command line test runner, use (--verbose)
296 . Turn on unit tests for UnitConverter
297 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
298 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
300 . Removed trailing whitespace from all text files, see
301 remote-trailing-whitespace.php maintenance script.
302 . Convert configuration to use property list backend.
304 3.2.0, released 2008-10-31
305 # Using %Core.CollectErrors forces line number/column tracking on, whereas
306 previously you could theoretically turn it off.
307 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
308 use handleEnd() instead.
309 ! %Output.AttrSort for when you need your attributes in alphabetical order to
310 deal with a bug in FCKEditor. Requested by frank farmer.
311 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
312 ! Proper support for name attribute. It is now allowed and equivalent to the id
313 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
314 is heavy (for all doctypes).
315 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
316 use on hand-written HTML.
317 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
318 the strategy to be used, standalone, on untrusted input.
319 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
320 processing of left angled brackets in smileys and other whatnot.
321 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
322 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
323 the --only-phpt parameter, although for backwards-compatibility the flag
325 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
326 Users who are not performing inbound filtering, this may seem a little
327 useless, but as a bonus, the test suite and handling of edge cases is also
329 ! Experimental implementation of forms for %HTML.Trusted
330 ! Track column numbers when maintain line numbers is on
331 ! Proprietary 'background' attribute on table-related elements converted into
332 corresponding CSS. Thanks Fusemail for sponsoring this feature!
333 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
335 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
336 time of operation varies slightly from notifyEnd() as *all* end tokens are
337 processed by the injector before they are subject to the well-formedness rules.
338 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
339 basename of image when not present.
340 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
341 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
342 the other involving an undefined $is_folder error.
343 - Throw error when %Core.Encoding is set to a spurious value. Previously,
344 this errored silently and returned false.
345 - Redirected stderr to stdout for flush error output.
346 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
348 - Do not re-munge URL if the output URL has the same host as the input URL.
350 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
351 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
352 - Fix bug with inline elements in blockquotes conflicting with strict doctype
353 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
354 - Fix bug where dots and double-dots in absolute URLs without hostname were
355 not collapsed by URIFilter_MakeAbsolute.
356 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
357 by reordering their addition.
358 - Will now throw exception on many error conditions during lexer creation; also
359 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
361 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
362 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
363 Reported by David Morton.
364 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
365 for more interesting filter-backtracking
366 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
367 index to reprocess tokens.
368 . StringHashParser now allows for multiline sections with "empty" content;
369 previously the section would remain undefined.
370 . Added --quick option to multitest.php, which tests only the most recent
371 release for each series.
372 . Added --distro option to multitest.php, which accepts either 'normal' or
373 'standalone'. This supercedes --exclude-normal and --exclude-standalone
375 3.1.1, released 2008-06-19
376 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
377 In order to enable this again, please set %URI.MungeResources to true.
378 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
379 and height/width HTML with %HTML.MaxImgLength.
380 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
381 for sponsoring this feature. Check out the corresponding documentation
382 for details. (Att Nightly testers: The API for this feature changed before
383 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
384 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
385 ! Implemented post URI filtering. Set member variable $post to true to set
387 ! Allow modules to define injectors via $info_injector. Injectors are
388 automatically disabled if injector's needed elements are not found.
389 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
390 Thanks Chris for sponsoring. If you've been using ad hoc code from the
391 forums, PLEASE use this instead.
392 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
393 embedded, tag name, attribute name, CSS property name). See %URI.Munge
394 for more details. Requested by Jochem Blok.
395 - Disable percent height/width attributes for img.
396 - AttrValidator operations are now atomic; updates to attributes are not
397 manifest in token until end of operations. This prevents naughty internal
398 code from directly modifying CurrentToken when they're not supposed to.
399 This semantics change was requested by frank farmer.
400 - Percent encoding checks enabled for URI query and fragment
401 - Fix stray backslashes in font-family; CSS Unicode character escapes are
402 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
404 - Improve parseCDATA algorithm to take into account newline normalization
405 - Account for browser confusion between Yen character and backslash in
406 Shift_JIS encoding. This fix generalizes to any other encoding which is not
407 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
408 - Fix missing configuration parameter in Generator calls. Thanks vs for the
410 - Improved adherence to Unicode by checking for non-character codepoints.
411 Thanks Geoffrey Sneddon for reporting. This may result in degraded
412 performance for extremely large inputs.
413 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
415 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
416 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
418 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
419 to __construct($min, $max). __construct(true) is equivalent to
421 . Added HTMLPurifier_AttrDef_Switch class
422 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
423 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
424 get this called with the configuration object. All modules now
425 use this rather than __construct(), although legacy code using constructors
426 will still work--the new format, however, lets modules access the
427 configuration object for HTML namespace dependant tweaks.
428 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
429 . ConfigSchema data-structure heavily optimized; on average it uses a third
430 the memory it did previously. The interface has changed accordingly,
431 consult changes to HTMLPurifier_Config for details.
432 . Variable parsing types now are magic integers instead of strings
433 . Added benchmark for ConfigSchema
434 . HTMLPurifier_Generator requires $config and $context parameters. If you
435 don't know what they should be, use HTMLPurifier_Config::createDefault()
436 and new HTMLPurifier_Context().
437 . Printers now properly distinguish between output configuration, and
438 target configuration. This is not applicable to scripts using
439 the Printers for HTML Purifier related tasks.
440 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
441 fatal errors will ensue.
442 . URIFilter->prepare can return false in order to abort loading of the filter
443 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
444 an external resource.
445 . %URI.Munge functionality factored out into a post-filter class.
446 . Added CurrentCSSProperty context variable during CSS validation
448 3.1.0, released 2008-05-18
449 # Unnecessary references to objects (vestiges of PHP4) removed from method
450 signatures. The following methods do not need references when assigning from
451 them and will result in E_STRICT errors if you try:
452 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
453 + HTMLPurifier_ConfigSchema::instance()
454 + HTMLPurifier_DefinitionCacheFactory::instance()
455 + HTMLPurifier_DefinitionCacheFactory->create()
456 + HTMLPurifier_DoctypeRegistry->register()
457 + HTMLPurifier_DoctypeRegistry->get()
458 + HTMLPurifier_HTMLModule->addElement()
459 + HTMLPurifier_HTMLModule->addBlankElement()
460 + HTMLPurifier_LanguageFactory::instance()
461 # Printer_ConfigForm's get*() functions were static-ified
462 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
463 form of tag@attr, NOT tag.attr (which will throw an error and won't do
464 anything). This is for forwards compatibility with XML; you'd do best
465 to migrate an %HTML.AllowedAttributes directives to this syntax too.
466 ! Allow index to be false for config from form creation
467 ! Added HTMLPurifier::VERSION constant
468 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
469 and allows for version numbers like "3.1.0-dev".
470 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
471 ! HTML Purifier's URI handling is a lot more robust, with much stricter
472 validation checks and better percent encoding handling. Thanks Gareth Heyes
473 for indicating security vulnerabilities from lax percent encoding.
474 ! Bootstrap autoloader deals more robustly with classes that don't exist,
475 preventing class_exists($class, true) from barfing.
476 - InterchangeBuilder now alphabetizes its lists

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

652 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
653 to better communicate its purpose
654 . Error unit tests can now specify the expectation of no errors. Future
655 iterations of the harness will be extremely strict about what errors

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

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

730 for output cache invalidation
731 . ConfigForm printer now can retrieve CSS and JS files as strings, in
732 case HTML Purifier's directory is not publically accessible
733 . Introduce new text/itext configuration directive values: these represent
734 longer strings that would be more appropriately edited with a textarea

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

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

764 linkify your HTML input by setting %AutoFormat.AutoParagraph and
765 %AutoFormat.Linkify to true
766 ! Newlines normalized internally, and then converted back to the
767 value of PHP_EOL. If this is not desired, set your newline format
768 using %Output.Newline.
769 ! Beta error collection, messages are implemented for the most generic
770 cases involving Lexing or Strategies
771 - Clean up special case code for <script> tags

805 # Completely refactored HTMLModuleManager, decentralizing safety
807 # Transform modules changed to Tidy modules, which offer more flexibility
808 and better modularization
809 # Configuration object now finalizes itself when a read operation is
810 performed on it, ensuring that its internal state stays consistent.
811 To revert this behavior, you can set the $autoFinalize member variable

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