4 = KEY ====================
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 ! Support for more white-space CSS values.
19 ! Permit underscores in font families
20 - Use prepend for SPL autoloading on PHP 5.3 and later.
21 - Fix bug with nofollow transform when pre-existing rel exists.
22 - Fix bug where background:url() always gets lower-cased
23 (but not background-image:url())
25 4.4.0, released 2012-01-18
26 # Removed PEARSax3 handler.
27 # URI.Munge now munges URIs inside the same host that go from https
28 to http. Reported by Neike Taika-Tessaro.
29 # Core.EscapeNonASCIICharacters now always transforms entities to
30 entities, even if target encoding is UTF-8.
31 # Tighten up selector validation in ExtractStyleBlocks.
32 Non-syntactically valid selectors are now rejected, along with
33 some of the more obscure ones such as attribute selectors, the
34 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
35 ID and class selectors now work properly with the relevant
36 configuration attributes. Also, mute errors when parsing CSS
37 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
38 ! Added support for 'scope' attribute on tables.
39 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
40 ! Properly handle sub-lists directly nested inside of lists in
41 a standards compliant way, by moving them into the preceding <li>
42 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
43 limited allowed comments in untrusted situations.
44 ! Implement iframes, and allow them to be used in untrusted mode with
45 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
46 <brad.froehle@gmail.com> for submitting an initial version of the patch.
47 ! The Forms module now works properly for transitional doctypes.
48 ! Added support for internationalized domain names. You need the PEAR
49 Net_IDNA2 module to be in your path; if it is installed, ensure the
50 class can be loaded and then set %Core.EnableIDNA to true.
51 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
52 <yramirez-htmlpurifier@adicio.com> for reporting.
53 - Explicitly initialize anonModule variable to null.
54 - Do not duplicate nofollow if already present. Thanks 178
56 - Do not add nofollow if hostname matches our current host. Thanks 178
57 for reporting, and Neike Taika-Tessaro for helping diagnose.
58 - Do not unset parser variable; this fixes intermittent serialization
59 problems. Thanks Neike Taika-Tessaro for reporting, bill
60 <10010tiger@gmail.com> for diagnosing.
61 - Fix iconv truncation bug, where non-UTF-8 target encodings see
62 output truncated after around 8000 characters. Thanks Jörg Ludwig
63 <joerg.ludwig@iserv.eu> for reporting.
64 - Fix broken table content model for XHTML1.1 (and also earlier
65 versions, although the W3C validator doesn't catch those violations).
66 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
68 4.3.0, released 2011-03-27
69 # Fixed broken caching of customized raw definitions, but requires an
70 API change. The old API still works but will emit a warning,
71 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
72 for how to upgrade your code.
73 # Protect against Internet Explorer innerHTML behavior by specially
74 treating attributes with backticks but no angled brackets, quotes or
75 spaces. This constitutes a slight semantic change, which can be
76 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
78 # Protect against cssText/innerHTML by restricting allowed characters
79 used in fonts further than mandated by the specification and encoding
80 some extra special characters in URLs. Reported by Neike
81 Taika-Tessaro and Mario Heiderich.
82 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
83 ! More types of SPL autoloaders allowed on later versions of PHP.
84 ! Implementations for position, top, left, right, bottom, z-index
85 when %CSS.Trusted is on.
86 ! Add %Cache.SerializerPermissions option for custom serializer
87 directory/file permissions
88 ! Fix longstanding bug in Flash support for non-IE browsers, and
89 allow more wmode attributes.
90 ! Add %CSS.AllowedFonts to restrict permissible font names.
91 - Switch to an iterative traversal of the DOM, which prevents us
92 from running out of stack space for deeply nested documents.
93 Thanks Maxim Krizhanovsky for contributing a patch.
94 - Make removal of conditional IE comments ungreedy; thanks Bernd
96 - Escape CDATA before removing Internet Explorer comments.
97 - Fix removal of id attributes under certain conditions by ensuring
98 armor attributes are preserved when recreating tags.
99 - Check if schema.ser was corrupted.
100 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
101 This safety check is only done for HTMLPurifier.auto.php; if you
102 are using standalone or the specialized includes files, you're
103 expected to know what you're doing.
104 - Stop repeatedly writing the cache file after I'm done customizing a
105 raw definition. Reported by ajh.
106 - Switch to using require_once in the Bootstrap to work around bad
107 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
108 - Fix URI handling when hostname is missing but scheme is present.
109 Reported by Neike Taika-Tessaro.
110 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
112 - Fix harmless notice from indexing into empty string. Thanks Matthijs
113 Kooijman <matthijs@stdin.nl> for reporting.
114 - Don't autoclose no parent elements are able to support the element
115 that triggered the autoclose. In particular fixes strange behavior
116 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
117 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
119 4.2.0, released 2010-09-15
120 ! Added %Core.RemoveProcessingInstructions, which lets you remove
121 <? ... ?> statements.
122 ! Added %URI.DisableResources functionality; the directive originally
123 did nothing. Thanks David Rothstein for reporting.
124 ! Add documentation about configuration directive types.
125 ! Add %CSS.ForbiddenProperties configuration directive.
126 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
127 to utilize full-screen mode.
128 ! Add optional support for the <code>file</code> URI scheme, enable
129 by explicitly setting %URI.AllowedSchemes.
130 ! Add %Core.NormalizeNewlines options to allow turning off newline
132 - Fix improper handling of Internet Explorer conditional comments
133 by parser. Thanks zmonteca for reporting.
134 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
135 Thanks sidepodcast for the fix.
136 - Warn if an element is allowed, but an attribute it requires is
139 4.1.1, released 2010-05-31
140 - Fix undefined index warnings in maintenance scripts.
141 - Fix bug in DirectLex for parsing elements with a single attribute
143 - Rewrite CSS output logic for font-family and url(). Thanks Mario
144 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
145 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
146 - Emit an error for CollectErrors if a body is extracted
147 - Fix bug where in background-position for center keyword handling.
148 - Fix infinite loop when a wrapper element is inserted in a context
149 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
150 - Remove +x bit and shebang from index.php; only supported mode is to
151 explicitly call it with php.
152 - Make test script less chatty when log_errors is on.
154 4.1.0, released 2010-04-26
155 ! Support proprietary height attribute on table element
156 ! Support YouTube slideshows that contain /cp/ in their URL.
157 ! Support for data: URI scheme; not enabled by default, add it using
159 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
160 ! Support for Internet Explorer compatibility with %HTML.SafeObject
161 using %Output.FlashCompat.
162 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
163 - Always quote the insides of url(...) in CSS.
165 4.0.0, released 2009-07-07
166 # APIs for ConfigSchema subsystem have substantially changed. See
167 docs/dev-config-bcbreaks.txt for details; in essence, anything that
168 had both namespace and directive now have a single unified key.
169 # Some configuration directives were renamed, specifically:
170 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
171 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
172 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
173 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
174 As usual, the old directive names will still work, but will throw E_NOTICE
176 # The allowed values for class have been relaxed to allow all of CDATA for
177 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
178 %Attr.ClassUseCDATA to false.
179 # Instead of appending the content model to an old content model, a blank
180 element will replace the old content model. You can use #SUPER to get
181 the old content model.
182 ! More robust support for name="" and id=""
183 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
184 configuration, and have changes to that configuration be propagated
185 to all of its children.
186 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
187 the name attribute when set. Use with care. Thanks Ian Cook for
189 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
190 tags that contain non-breaking spaces as well other whitespace. You
191 can also modify which tags should have maintained with
192 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
193 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
194 classes users can use to a specified finite set of classes, and
195 %Attr.ForbiddenClasses, which is the logical inverse.
196 ! You can now maintain your own configuration schema directories by
197 creating a config-schema.php file or passing an extra argument. Check
198 docs/dev-config-schema.html for more details.
199 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
200 your configuration in a compact serial file, which you can unserialize
201 and use directly without having to go through the overhead of setup.
202 - Fix bug where URIDefinition would not get cleared if it's directives got
204 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
205 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
206 - Make %URI.Munge not apply to links that have the same host as your host.
207 - Prevent stray </body> tag from truncating output, if a second </body>
209 . Created script maintenance/rename-config.php for renaming a configuration
210 directive while maintaining its alias. This script does not change source code.
211 . Implement namespace locking for definition construction, to prevent
212 bugs where a directive is used for definition construction but is not
213 used to construct the cache hash.
215 3.3.0, released 2009-02-16
216 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
217 ! Implement generic property list classess
218 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
219 does not do the "right thing" with characters not supported in the output
221 - Spellcheck UTF-8: The Secret To Character Encoding
222 - Fix improper removal of the contents of elements with only whitespace. Thanks
223 Eric Wald for reporting.
224 - Fix broken test suite in versions of PHP without spl_autoload_register()
225 - Fix degenerate case with YouTube filter involving double hyphens.
226 Thanks Pierre Attar for reporting.
227 - Fix YouTube rendering problem on certain versions of Firefox.
228 - Fix CSSDefinition Printer problems with decorators
229 - Add text parameter to unit tests, forces text output
230 . Add verbose mode to command line test runner, use (--verbose)
231 . Turn on unit tests for UnitConverter
232 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
233 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
235 . Removed trailing whitespace from all text files, see
236 remote-trailing-whitespace.php maintenance script.
237 . Convert configuration to use property list backend.
239 3.2.0, released 2008-10-31
240 # Using %Core.CollectErrors forces line number/column tracking on, whereas
241 previously you could theoretically turn it off.
242 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
243 use handleEnd() instead.
244 ! %Output.AttrSort for when you need your attributes in alphabetical order to
245 deal with a bug in FCKEditor. Requested by frank farmer.
246 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
247 ! Proper support for name attribute. It is now allowed and equivalent to the id
248 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
249 is heavy (for all doctypes).
250 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
251 use on hand-written HTML.
252 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
253 the strategy to be used, standalone, on untrusted input.
254 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
255 processing of left angled brackets in smileys and other whatnot.
256 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
257 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
258 the --only-phpt parameter, although for backwards-compatibility the flag
260 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
261 Users who are not performing inbound filtering, this may seem a little
262 useless, but as a bonus, the test suite and handling of edge cases is also
264 ! Experimental implementation of forms for %HTML.Trusted
265 ! Track column numbers when maintain line numbers is on
266 ! Proprietary 'background' attribute on table-related elements converted into
267 corresponding CSS. Thanks Fusemail for sponsoring this feature!
268 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
270 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
271 time of operation varies slightly from notifyEnd() as *all* end tokens are
272 processed by the injector before they are subject to the well-formedness rules.
273 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
274 basename of image when not present.
275 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
276 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
277 the other involving an undefined $is_folder error.
278 - Throw error when %Core.Encoding is set to a spurious value. Previously,
279 this errored silently and returned false.
280 - Redirected stderr to stdout for flush error output.
281 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
283 - Do not re-munge URL if the output URL has the same host as the input URL.
285 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
286 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
287 - Fix bug with inline elements in blockquotes conflicting with strict doctype
288 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
289 - Fix bug where dots and double-dots in absolute URLs without hostname were
290 not collapsed by URIFilter_MakeAbsolute.
291 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
292 by reordering their addition.
293 - Will now throw exception on many error conditions during lexer creation; also
294 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
296 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
297 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
298 Reported by David Morton.
299 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
300 for more interesting filter-backtracking
301 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
302 index to reprocess tokens.
303 . StringHashParser now allows for multiline sections with "empty" content;
304 previously the section would remain undefined.
305 . Added --quick option to multitest.php, which tests only the most recent
306 release for each series.
307 . Added --distro option to multitest.php, which accepts either 'normal' or
308 'standalone'. This supercedes --exclude-normal and --exclude-standalone
310 3.1.1, released 2008-06-19
311 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
312 In order to enable this again, please set %URI.MungeResources to true.
313 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
314 and height/width HTML with %HTML.MaxImgLength.
315 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
316 for sponsoring this feature. Check out the corresponding documentation
317 for details. (Att Nightly testers: The API for this feature changed before
318 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
319 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
320 ! Implemented post URI filtering. Set member variable $post to true to set
322 ! Allow modules to define injectors via $info_injector. Injectors are
323 automatically disabled if injector's needed elements are not found.
324 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
325 Thanks Chris for sponsoring. If you've been using ad hoc code from the
326 forums, PLEASE use this instead.
327 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
328 embedded, tag name, attribute name, CSS property name). See %URI.Munge
329 for more details. Requested by Jochem Blok.
330 - Disable percent height/width attributes for img.
331 - AttrValidator operations are now atomic; updates to attributes are not
332 manifest in token until end of operations. This prevents naughty internal
333 code from directly modifying CurrentToken when they're not supposed to.
334 This semantics change was requested by frank farmer.
335 - Percent encoding checks enabled for URI query and fragment
336 - Fix stray backslashes in font-family; CSS Unicode character escapes are
337 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
339 - Improve parseCDATA algorithm to take into account newline normalization
340 - Account for browser confusion between Yen character and backslash in
341 Shift_JIS encoding. This fix generalizes to any other encoding which is not
342 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
343 - Fix missing configuration parameter in Generator calls. Thanks vs for the
345 - Improved adherence to Unicode by checking for non-character codepoints.
346 Thanks Geoffrey Sneddon for reporting. This may result in degraded
347 performance for extremely large inputs.
348 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
350 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
351 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
353 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
354 to __construct($min, $max). __construct(true) is equivalent to
356 . Added HTMLPurifier_AttrDef_Switch class
357 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
358 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
359 get this called with the configuration object. All modules now
360 use this rather than __construct(), although legacy code using constructors
361 will still work--the new format, however, lets modules access the
362 configuration object for HTML namespace dependant tweaks.
363 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
364 . ConfigSchema data-structure heavily optimized; on average it uses a third
365 the memory it did previously. The interface has changed accordingly,
366 consult changes to HTMLPurifier_Config for details.
367 . Variable parsing types now are magic integers instead of strings
368 . Added benchmark for ConfigSchema
369 . HTMLPurifier_Generator requires $config and $context parameters. If you
370 don't know what they should be, use HTMLPurifier_Config::createDefault()
371 and new HTMLPurifier_Context().
372 . Printers now properly distinguish between output configuration, and
373 target configuration. This is not applicable to scripts using
374 the Printers for HTML Purifier related tasks.
375 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
376 fatal errors will ensue.
377 . URIFilter->prepare can return false in order to abort loading of the filter
378 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
379 an external resource.
380 . %URI.Munge functionality factored out into a post-filter class.
381 . Added CurrentCSSProperty context variable during CSS validation
383 3.1.0, released 2008-05-18
384 # Unnecessary references to objects (vestiges of PHP4) removed from method
385 signatures. The following methods do not need references when assigning from
386 them and will result in E_STRICT errors if you try:
387 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
388 + HTMLPurifier_ConfigSchema::instance()
389 + HTMLPurifier_DefinitionCacheFactory::instance()
390 + HTMLPurifier_DefinitionCacheFactory->create()
391 + HTMLPurifier_DoctypeRegistry->register()
392 + HTMLPurifier_DoctypeRegistry->get()
393 + HTMLPurifier_HTMLModule->addElement()
394 + HTMLPurifier_HTMLModule->addBlankElement()
395 + HTMLPurifier_LanguageFactory::instance()
396 # Printer_ConfigForm's get*() functions were static-ified
397 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
398 form of tag@attr, NOT tag.attr (which will throw an error and won't do
399 anything). This is for forwards compatibility with XML; you'd do best
400 to migrate an %HTML.AllowedAttributes directives to this syntax too.
401 ! Allow index to be false for config from form creation
402 ! Added HTMLPurifier::VERSION constant
403 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
404 and allows for version numbers like "3.1.0-dev".
405 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
406 ! HTML Purifier's URI handling is a lot more robust, with much stricter
407 validation checks and better percent encoding handling. Thanks Gareth Heyes
408 for indicating security vulnerabilities from lax percent encoding.
409 ! Bootstrap autoloader deals more robustly with classes that don't exist,
410 preventing class_exists($class, true) from barfing.
411 - InterchangeBuilder now alphabetizes its lists
412 - Validation error in configdoc output fixed
413 - Iconv and other encoding errors muted even with custom error handlers that
414 do not honor error_reporting
415 - Add protection against imagecrash attack with CSS height/width
416 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
417 - Fixed and revamped broken ConfigForm smoketest
418 - Bug with bool/null fields in Printer_ConfigForm fixed
419 - Bug with global forbidden attributes fixed
420 - Improved error messages for allowed and forbidden HTML elements and attributes
421 - Missing (or null) in configdoc documentation restored
422 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
423 of DOM), HTML Purifier punts to DirectLex
424 - Fatal error with unserialization of ScriptRequired
425 - Created directories are now chmod'ed properly
426 - Fixed bug with fallback languages in LanguageFactory
427 - Standalone testing setup properly with autoload
428 . Out-of-date documentation revised
429 . UTF-8 encoding check optimization as suggested by Diego
430 . HTMLPurifier_Error removed in favor of exceptions
431 . More copy() function removed; should use clone instead
432 . More extensive unit tests for HTMLDefinition
433 . assertPurification moved to central harness
434 . HTMLPurifier_Generator accepts $config and $context parameters during
435 instantiation, not runtime
436 . Double-quotes outside of attribute values are now unescaped
438 3.1.0rc1, released 2008-04-22
439 # Autoload support added. Internal require_once's removed in favor of an
440 explicit require list or autoloading. To use HTML Purifier,
441 you must now either use HTMLPurifier.auto.php
442 or HTMLPurifier.includes.php; setting the include path and including
443 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
444 as well to register our autoload handler (or modify your autoload function
445 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
446 HTMLPurifier.safe-includes.php for a less performance friendly but more
447 user-friendly library load.
448 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
449 information is stored in the ConfigSchema directory, and the
450 maintenance/generate-schema-cache.php generates the schema.ser file, which
451 is now instantiated. Support for userland schema changes coming soon!
452 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
453 alias; to get rid of these errors just modify your configuration to use
454 the new directive name.
455 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
456 enabled using %Filter.$filter_name or by setting your own filters using
458 # Directive-level safety properties superceded in favor of module-level
459 safety. Internal method HTMLModule->addElement() has changed, although
460 the externally visible HTMLDefinition->addElement has *not* changed.
461 ! Extra utility classes for testing and non-library operations can
462 be found in extras/. Specifically, these are FSTools and ConfigDoc.
463 You may find a use for these in your own project, but right now they
464 are highly experimental and volatile.
465 ! Integration with PHPT allows for automated smoketests
466 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
467 by Chris. You can enable them with %HTML.Proprietary if your client
469 ! Support for !important CSS cascade modifier. By default, this will be stripped
470 from CSS, but you can enable it using %CSS.AllowImportant
471 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
