10 ==========================
12 4.5.0, unknown release date
13 # Fix bug where stacked attribute transforms clobber each other;
14 this also means it's no longer possible to override attribute
15 transforms in later modules. No internal code was using this
16 but this may break some clients.
17 ! Support display:inline-block
18 - Use prepend for SPL autoloading on PHP 5.3 and later.
19 - Fix bug with nofollow transform when pre-existing rel exists.
21 4.4.0, released 2012-01-18
22 # Removed PEARSax3 handler.
23 # URI.Munge now munges URIs inside the same host that go from https
24 to http. Reported by Neike Taika-Tessaro.
25 # Core.EscapeNonASCIICharacters now always transforms entities to
26 entities, even if target encoding is UTF-8.
27 # Tighten up selector validation in ExtractStyleBlocks.
28 Non-syntactically valid selectors are now rejected, along with
29 some of the more obscure ones such as attribute selectors, the
30 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
31 ID and class selectors now work properly with the relevant
32 configuration attributes. Also, mute errors when parsing CSS
33 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
34 ! Added support for 'scope' attribute on tables.
35 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
36 ! Properly handle sub-lists directly nested inside of lists in
37 a standards compliant way, by moving them into the preceding <li>
38 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
39 limited allowed comments in untrusted situations.
40 ! Implement iframes, and allow them to be used in untrusted mode with
41 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
42 <brad.froehle@gmail.com> for submitting an initial version of the patch.
43 ! The Forms module now works properly for transitional doctypes.
44 ! Added support for internationalized domain names. You need the PEAR
45 Net_IDNA2 module to be in your path; if it is installed, ensure the
46 class can be loaded and then set %Core.EnableIDNA to true.
47 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
48 <yramirez-htmlpurifier@adicio.com> for reporting.
49 - Explicitly initialize anonModule variable to null.
50 - Do not duplicate nofollow if already present. Thanks 178
52 - Do not add nofollow if hostname matches our current host. Thanks 178
53 for reporting, and Neike Taika-Tessaro for helping diagnose.
54 - Do not unset parser variable; this fixes intermittent serialization
55 problems. Thanks Neike Taika-Tessaro for reporting, bill
56 <10010tiger@gmail.com> for diagnosing.
57 - Fix iconv truncation bug, where non-UTF-8 target encodings see
58 output truncated after around 8000 characters. Thanks Jörg Ludwig
59 <joerg.ludwig@iserv.eu> for reporting.
60 - Fix broken table content model for XHTML1.1 (and also earlier
61 versions, although the W3C validator doesn't catch those violations).
62 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
64 4.3.0, released 2011-03-27
65 # Fixed broken caching of customized raw definitions, but requires an
66 API change. The old API still works but will emit a warning,
67 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
68 for how to upgrade your code.
69 # Protect against Internet Explorer innerHTML behavior by specially
70 treating attributes with backticks but no angled brackets, quotes or
71 spaces. This constitutes a slight semantic change, which can be
72 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
74 # Protect against cssText/innerHTML by restricting allowed characters
75 used in fonts further than mandated by the specification and encoding
76 some extra special characters in URLs. Reported by Neike
77 Taika-Tessaro and Mario Heiderich.
78 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
79 ! More types of SPL autoloaders allowed on later versions of PHP.
80 ! Implementations for position, top, left, right, bottom, z-index
81 when %CSS.Trusted is on.
82 ! Add %Cache.SerializerPermissions option for custom serializer
83 directory/file permissions
84 ! Fix longstanding bug in Flash support for non-IE browsers, and
85 allow more wmode attributes.
86 ! Add %CSS.AllowedFonts to restrict permissible font names.
87 - Switch to an iterative traversal of the DOM, which prevents us
88 from running out of stack space for deeply nested documents.
89 Thanks Maxim Krizhanovsky for contributing a patch.
90 - Make removal of conditional IE comments ungreedy; thanks Bernd
92 - Escape CDATA before removing Internet Explorer comments.
93 - Fix removal of id attributes under certain conditions by ensuring
94 armor attributes are preserved when recreating tags.
95 - Check if schema.ser was corrupted.
96 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
97 This safety check is only done for HTMLPurifier.auto.php; if you
98 are using standalone or the specialized includes files, you're
99 expected to know what you're doing.
100 - Stop repeatedly writing the cache file after I'm done customizing a
101 raw definition. Reported by ajh.
102 - Switch to using require_once in the Bootstrap to work around bad
103 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
104 - Fix URI handling when hostname is missing but scheme is present.
105 Reported by Neike Taika-Tessaro.
106 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
108 - Fix harmless notice from indexing into empty string. Thanks Matthijs
109 Kooijman <matthijs@stdin.nl> for reporting.
110 - Don't autoclose no parent elements are able to support the element
111 that triggered the autoclose. In particular fixes strange behavior
112 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
113 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
115 4.2.0, released 2010-09-15
116 ! Added %Core.RemoveProcessingInstructions, which lets you remove
117 <? ... ?> statements.
118 ! Added %URI.DisableResources functionality; the directive originally
119 did nothing. Thanks David Rothstein for reporting.
120 ! Add documentation about configuration directive types.
121 ! Add %CSS.ForbiddenProperties configuration directive.
122 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
123 to utilize full-screen mode.
124 ! Add optional support for the <code>file</code> URI scheme, enable
125 by explicitly setting %URI.AllowedSchemes.
126 ! Add %Core.NormalizeNewlines options to allow turning off newline
128 - Fix improper handling of Internet Explorer conditional comments
129 by parser. Thanks zmonteca for reporting.
130 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
131 Thanks sidepodcast for the fix.
132 - Warn if an element is allowed, but an attribute it requires is
135 4.1.1, released 2010-05-31
136 - Fix undefined index warnings in maintenance scripts.
137 - Fix bug in DirectLex for parsing elements with a single attribute
139 - Rewrite CSS output logic for font-family and url(). Thanks Mario
140 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
141 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
142 - Emit an error for CollectErrors if a body is extracted
143 - Fix bug where in background-position for center keyword handling.
144 - Fix infinite loop when a wrapper element is inserted in a context
145 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
146 - Remove +x bit and shebang from index.php; only supported mode is to
147 explicitly call it with php.
148 - Make test script less chatty when log_errors is on.
150 4.1.0, released 2010-04-26
151 ! Support proprietary height attribute on table element
152 ! Support YouTube slideshows that contain /cp/ in their URL.
153 ! Support for data: URI scheme; not enabled by default, add it using
155 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
156 ! Support for Internet Explorer compatibility with %HTML.SafeObject
157 using %Output.FlashCompat.
158 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
159 - Always quote the insides of url(...) in CSS.
161 4.0.0, released 2009-07-07
162 # APIs for ConfigSchema subsystem have substantially changed. See
163 docs/dev-config-bcbreaks.txt for details; in essence, anything that
164 had both namespace and directive now have a single unified key.
165 # Some configuration directives were renamed, specifically:
166 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
167 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
168 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
169 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
170 As usual, the old directive names will still work, but will throw E_NOTICE
172 # The allowed values for class have been relaxed to allow all of CDATA for
173 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
174 %Attr.ClassUseCDATA to false.
175 # Instead of appending the content model to an old content model, a blank
176 element will replace the old content model. You can use #SUPER to get
177 the old content model.
178 ! More robust support for name="" and id=""
179 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
180 configuration, and have changes to that configuration be propagated
181 to all of its children.
182 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
183 the name attribute when set. Use with care. Thanks Ian Cook for
185 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
186 tags that contain non-breaking spaces as well other whitespace. You
187 can also modify which tags should have maintained with
188 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
189 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
190 classes users can use to a specified finite set of classes, and
191 %Attr.ForbiddenClasses, which is the logical inverse.
192 ! You can now maintain your own configuration schema directories by
193 creating a config-schema.php file or passing an extra argument. Check
194 docs/dev-config-schema.html for more details.
195 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
196 your configuration in a compact serial file, which you can unserialize
197 and use directly without having to go through the overhead of setup.
198 - Fix bug where URIDefinition would not get cleared if it's directives got
200 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
201 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
202 - Make %URI.Munge not apply to links that have the same host as your host.
203 - Prevent stray </body> tag from truncating output, if a second </body>
205 . Created script maintenance/rename-config.php for renaming a configuration
206 directive while maintaining its alias. This script does not change source code.
207 . Implement namespace locking for definition construction, to prevent
208 bugs where a directive is used for definition construction but is not
209 used to construct the cache hash.
211 3.3.0, released 2009-02-16
212 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
213 ! Implement generic property list classess
214 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
215 does not do the "right thing" with characters not supported in the output
217 - Spellcheck UTF-8: The Secret To Character Encoding
218 - Fix improper removal of the contents of elements with only whitespace. Thanks
219 Eric Wald for reporting.
220 - Fix broken test suite in versions of PHP without spl_autoload_register()
221 - Fix degenerate case with YouTube filter involving double hyphens.
222 Thanks Pierre Attar for reporting.
223 - Fix YouTube rendering problem on certain versions of Firefox.
224 - Fix CSSDefinition Printer problems with decorators
225 - Add text parameter to unit tests, forces text output
226 . Add verbose mode to command line test runner, use (--verbose)
227 . Turn on unit tests for UnitConverter
228 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
229 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
231 . Removed trailing whitespace from all text files, see
232 remote-trailing-whitespace.php maintenance script.
233 . Convert configuration to use property list backend.
235 3.2.0, released 2008-10-31
236 # Using %Core.CollectErrors forces line number/column tracking on, whereas
237 previously you could theoretically turn it off.
238 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
239 use handleEnd() instead.
240 ! %Output.AttrSort for when you need your attributes in alphabetical order to
241 deal with a bug in FCKEditor. Requested by frank farmer.
242 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
243 ! Proper support for name attribute. It is now allowed and equivalent to the id
244 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
245 is heavy (for all doctypes).
246 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
247 use on hand-written HTML.
248 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
249 the strategy to be used, standalone, on untrusted input.
250 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
251 processing of left angled brackets in smileys and other whatnot.
252 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
253 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
254 the --only-phpt parameter, although for backwards-compatibility the flag
256 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
257 Users who are not performing inbound filtering, this may seem a little
258 useless, but as a bonus, the test suite and handling of edge cases is also
260 ! Experimental implementation of forms for %HTML.Trusted
261 ! Track column numbers when maintain line numbers is on
262 ! Proprietary 'background' attribute on table-related elements converted into
263 corresponding CSS. Thanks Fusemail for sponsoring this feature!
264 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
266 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
267 time of operation varies slightly from notifyEnd() as *all* end tokens are
268 processed by the injector before they are subject to the well-formedness rules.
269 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
270 basename of image when not present.
271 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
272 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
273 the other involving an undefined $is_folder error.
274 - Throw error when %Core.Encoding is set to a spurious value. Previously,
275 this errored silently and returned false.
276 - Redirected stderr to stdout for flush error output.
277 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
279 - Do not re-munge URL if the output URL has the same host as the input URL.
281 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
282 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
283 - Fix bug with inline elements in blockquotes conflicting with strict doctype
284 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
285 - Fix bug where dots and double-dots in absolute URLs without hostname were
286 not collapsed by URIFilter_MakeAbsolute.
287 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
288 by reordering their addition.
289 - Will now throw exception on many error conditions during lexer creation; also
290 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
292 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
293 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
294 Reported by David Morton.
295 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
296 for more interesting filter-backtracking
297 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
298 index to reprocess tokens.
299 . StringHashParser now allows for multiline sections with "empty" content;
300 previously the section would remain undefined.
301 . Added --quick option to multitest.php, which tests only the most recent
302 release for each series.
303 . Added --distro option to multitest.php, which accepts either 'normal' or
304 'standalone'. This supercedes --exclude-normal and --exclude-standalone
306 3.1.1, released 2008-06-19
307 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
308 In order to enable this again, please set %URI.MungeResources to true.
309 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
310 and height/width HTML with %HTML.MaxImgLength.
311 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
312 for sponsoring this feature. Check out the corresponding documentation
313 for details. (Att Nightly testers: The API for this feature changed before
314 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
315 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
316 ! Implemented post URI filtering. Set member variable $post to true to set
318 ! Allow modules to define injectors via $info_injector. Injectors are
319 automatically disabled if injector's needed elements are not found.
320 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
321 Thanks Chris for sponsoring. If you've been using ad hoc code from the
322 forums, PLEASE use this instead.
323 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
324 embedded, tag name, attribute name, CSS property name). See %URI.Munge
325 for more details. Requested by Jochem Blok.
326 - Disable percent height/width attributes for img.
327 - AttrValidator operations are now atomic; updates to attributes are not
328 manifest in token until end of operations. This prevents naughty internal
329 code from directly modifying CurrentToken when they're not supposed to.
330 This semantics change was requested by frank farmer.
331 - Percent encoding checks enabled for URI query and fragment
332 - Fix stray backslashes in font-family; CSS Unicode character escapes are
333 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
335 - Improve parseCDATA algorithm to take into account newline normalization
336 - Account for browser confusion between Yen character and backslash in
337 Shift_JIS encoding. This fix generalizes to any other encoding which is not
338 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
339 - Fix missing configuration parameter in Generator calls. Thanks vs for the
341 - Improved adherence to Unicode by checking for non-character codepoints.
342 Thanks Geoffrey Sneddon for reporting. This may result in degraded
343 performance for extremely large inputs.
344 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
346 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
347 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
349 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
350 to __construct($min, $max). __construct(true) is equivalent to
352 . Added HTMLPurifier_AttrDef_Switch class
353 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
354 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
355 get this called with the configuration object. All modules now
356 use this rather than __construct(), although legacy code using constructors
357 will still work--the new format, however, lets modules access the
358 configuration object for HTML namespace dependant tweaks.
359 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
360 . ConfigSchema data-structure heavily optimized; on average it uses a third
361 the memory it did previously. The interface has changed accordingly,
362 consult changes to HTMLPurifier_Config for details.
363 . Variable parsing types now are magic integers instead of strings
364 . Added benchmark for ConfigSchema
365 . HTMLPurifier_Generator requires $config and $context parameters. If you
366 don't know what they should be, use HTMLPurifier_Config::createDefault()
367 and new HTMLPurifier_Context().
368 . Printers now properly distinguish between output configuration, and
369 target configuration. This is not applicable to scripts using
370 the Printers for HTML Purifier related tasks.
371 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
372 fatal errors will ensue.
373 . URIFilter->prepare can return false in order to abort loading of the filter
374 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
375 an external resource.
376 . %URI.Munge functionality factored out into a post-filter class.
377 . Added CurrentCSSProperty context variable during CSS validation
379 3.1.0, released 2008-05-18
380 # Unnecessary references to objects (vestiges of PHP4) removed from method
381 signatures. The following methods do not need references when assigning from
382 them and will result in E_STRICT errors if you try:
383 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
384 + HTMLPurifier_ConfigSchema::instance()
385 + HTMLPurifier_DefinitionCacheFactory::instance()
386 + HTMLPurifier_DefinitionCacheFactory->create()
387 + HTMLPurifier_DoctypeRegistry->register()
388 + HTMLPurifier_DoctypeRegistry->get()
389 + HTMLPurifier_HTMLModule->addElement()
390 + HTMLPurifier_HTMLModule->addBlankElement()
391 + HTMLPurifier_LanguageFactory::instance()
392 # Printer_ConfigForm's get*() functions were static-ified
393 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
394 form of tag@attr, NOT tag.attr (which will throw an error and won't do
395 anything). This is for forwards compatibility with XML; you'd do best
396 to migrate an %HTML.AllowedAttributes directives to this syntax too.
397 ! Allow index to be false for config from form creation
398 ! Added HTMLPurifier::VERSION constant
399 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
400 and allows for version numbers like "3.1.0-dev".
401 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
402 ! HTML Purifier's URI handling is a lot more robust, with much stricter
403 validation checks and better percent encoding handling. Thanks Gareth Heyes
404 for indicating security vulnerabilities from lax percent encoding.
405 ! Bootstrap autoloader deals more robustly with classes that don't exist,
406 preventing class_exists($class, true) from barfing.
407 - InterchangeBuilder now alphabetizes its lists
408 - Validation error in configdoc output fixed
409 - Iconv and other encoding errors muted even with custom error handlers that
410 do not honor error_reporting
411 - Add protection against imagecrash attack with CSS height/width
412 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
413 - Fixed and revamped broken ConfigForm smoketest
414 - Bug with bool/null fields in Printer_ConfigForm fixed
415 - Bug with global forbidden attributes fixed
416 - Improved error messages for allowed and forbidden HTML elements and attributes
417 - Missing (or null) in configdoc documentation restored
418 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
419 of DOM), HTML Purifier punts to DirectLex
420 - Fatal error with unserialization of ScriptRequired
421 - Created directories are now chmod'ed properly
422 - Fixed bug with fallback languages in LanguageFactory
423 - Standalone testing setup properly with autoload
424 . Out-of-date documentation revised
425 . UTF-8 encoding check optimization as suggested by Diego
426 . HTMLPurifier_Error removed in favor of exceptions
427 . More copy() function removed; should use clone instead
428 . More extensive unit tests for HTMLDefinition
429 . assertPurification moved to central harness
430 . HTMLPurifier_Generator accepts $config and $context parameters during
431 instantiation, not runtime
432 . Double-quotes outside of attribute values are now unescaped
434 3.1.0rc1, released 2008-04-22
435 # Autoload support added. Internal require_once's removed in favor of an
436 explicit require list or autoloading. To use HTML Purifier,
437 you must now either use HTMLPurifier.auto.php
438 or HTMLPurifier.includes.php; setting the include path and including
439 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
440 as well to register our autoload handler (or modify your autoload function
441 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
442 HTMLPurifier.safe-includes.php for a less performance friendly but more
443 user-friendly library load.
444 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
445 information is stored in the ConfigSchema directory, and the
446 maintenance/generate-schema-cache.php generates the schema.ser file, which
447 is now instantiated. Support for userland schema changes coming soon!
448 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
449 alias; to get rid of these errors just modify your configuration to use
450 the new directive name.
451 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
452 enabled using %Filter.$filter_name or by setting your own filters using
454 # Directive-level safety properties superceded in favor of module-level
455 safety. Internal method HTMLModule->addElement() has changed, although
456 the externally visible HTMLDefinition->addElement has *not* changed.
457 ! Extra utility classes for testing and non-library operations can
458 be found in extras/. Specifically, these are FSTools and ConfigDoc.
459 You may find a use for these in your own project, but right now they
460 are highly experimental and volatile.
461 ! Integration with PHPT allows for automated smoketests
462 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
463 by Chris. You can enable them with %HTML.Proprietary if your client
465 ! Support for !important CSS cascade modifier. By default, this will be stripped
466 from CSS, but you can enable it using %CSS.AllowImportant
467 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
469 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
470 Developer error (not enduser error) can cause these to be triggered.
471 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
