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 ! Support for page-break-* CSS3 properties when proprietary properties
22 - Use prepend for SPL autoloading on PHP 5.3 and later.
23 - Fix bug with nofollow transform when pre-existing rel exists.
24 - Fix bug where background:url() always gets lower-cased
25 (but not background-image:url())
26 - Fix bug with non lower-case color names in HTML
27 - Fix bug where data URI validation doesn't remove temporary files.
28 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
29 - Don't remove certain empty tags on RemoveEmpty.
31 4.4.0, released 2012-01-18
32 # Removed PEARSax3 handler.
33 # URI.Munge now munges URIs inside the same host that go from https
34 to http. Reported by Neike Taika-Tessaro.
35 # Core.EscapeNonASCIICharacters now always transforms entities to
36 entities, even if target encoding is UTF-8.
37 # Tighten up selector validation in ExtractStyleBlocks.
38 Non-syntactically valid selectors are now rejected, along with
39 some of the more obscure ones such as attribute selectors, the
40 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
41 ID and class selectors now work properly with the relevant
42 configuration attributes. Also, mute errors when parsing CSS
43 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
44 ! Added support for 'scope' attribute on tables.
45 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
46 ! Properly handle sub-lists directly nested inside of lists in
47 a standards compliant way, by moving them into the preceding <li>
48 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
49 limited allowed comments in untrusted situations.
50 ! Implement iframes, and allow them to be used in untrusted mode with
51 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
52 <brad.froehle@gmail.com> for submitting an initial version of the patch.
53 ! The Forms module now works properly for transitional doctypes.
54 ! Added support for internationalized domain names. You need the PEAR
55 Net_IDNA2 module to be in your path; if it is installed, ensure the
56 class can be loaded and then set %Core.EnableIDNA to true.
57 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
58 <yramirez-htmlpurifier@adicio.com> for reporting.
59 - Explicitly initialize anonModule variable to null.
60 - Do not duplicate nofollow if already present. Thanks 178
62 - Do not add nofollow if hostname matches our current host. Thanks 178
63 for reporting, and Neike Taika-Tessaro for helping diagnose.
64 - Do not unset parser variable; this fixes intermittent serialization
65 problems. Thanks Neike Taika-Tessaro for reporting, bill
66 <10010tiger@gmail.com> for diagnosing.
67 - Fix iconv truncation bug, where non-UTF-8 target encodings see
68 output truncated after around 8000 characters. Thanks Jörg Ludwig
69 <joerg.ludwig@iserv.eu> for reporting.
70 - Fix broken table content model for XHTML1.1 (and also earlier
71 versions, although the W3C validator doesn't catch those violations).
72 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
74 4.3.0, released 2011-03-27
75 # Fixed broken caching of customized raw definitions, but requires an
76 API change. The old API still works but will emit a warning,
77 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
78 for how to upgrade your code.
79 # Protect against Internet Explorer innerHTML behavior by specially
80 treating attributes with backticks but no angled brackets, quotes or
81 spaces. This constitutes a slight semantic change, which can be
82 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
84 # Protect against cssText/innerHTML by restricting allowed characters
85 used in fonts further than mandated by the specification and encoding
86 some extra special characters in URLs. Reported by Neike
87 Taika-Tessaro and Mario Heiderich.
88 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
89 ! More types of SPL autoloaders allowed on later versions of PHP.
90 ! Implementations for position, top, left, right, bottom, z-index
91 when %CSS.Trusted is on.
92 ! Add %Cache.SerializerPermissions option for custom serializer
93 directory/file permissions
94 ! Fix longstanding bug in Flash support for non-IE browsers, and
95 allow more wmode attributes.
96 ! Add %CSS.AllowedFonts to restrict permissible font names.
97 - Switch to an iterative traversal of the DOM, which prevents us
98 from running out of stack space for deeply nested documents.
99 Thanks Maxim Krizhanovsky for contributing a patch.
100 - Make removal of conditional IE comments ungreedy; thanks Bernd
102 - Escape CDATA before removing Internet Explorer comments.
103 - Fix removal of id attributes under certain conditions by ensuring
104 armor attributes are preserved when recreating tags.
105 - Check if schema.ser was corrupted.
106 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
107 This safety check is only done for HTMLPurifier.auto.php; if you
108 are using standalone or the specialized includes files, you're
109 expected to know what you're doing.
110 - Stop repeatedly writing the cache file after I'm done customizing a
111 raw definition. Reported by ajh.
112 - Switch to using require_once in the Bootstrap to work around bad
113 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
114 - Fix URI handling when hostname is missing but scheme is present.
115 Reported by Neike Taika-Tessaro.
116 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
118 - Fix harmless notice from indexing into empty string. Thanks Matthijs
119 Kooijman <matthijs@stdin.nl> for reporting.
120 - Don't autoclose no parent elements are able to support the element
121 that triggered the autoclose. In particular fixes strange behavior
122 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
123 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
125 4.2.0, released 2010-09-15
126 ! Added %Core.RemoveProcessingInstructions, which lets you remove
127 <? ... ?> statements.
128 ! Added %URI.DisableResources functionality; the directive originally
129 did nothing. Thanks David Rothstein for reporting.
130 ! Add documentation about configuration directive types.
131 ! Add %CSS.ForbiddenProperties configuration directive.
132 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
133 to utilize full-screen mode.
134 ! Add optional support for the <code>file</code> URI scheme, enable
135 by explicitly setting %URI.AllowedSchemes.
136 ! Add %Core.NormalizeNewlines options to allow turning off newline
138 - Fix improper handling of Internet Explorer conditional comments
139 by parser. Thanks zmonteca for reporting.
140 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
141 Thanks sidepodcast for the fix.
142 - Warn if an element is allowed, but an attribute it requires is
145 4.1.1, released 2010-05-31
146 - Fix undefined index warnings in maintenance scripts.
147 - Fix bug in DirectLex for parsing elements with a single attribute
149 - Rewrite CSS output logic for font-family and url(). Thanks Mario
150 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
151 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
152 - Emit an error for CollectErrors if a body is extracted
153 - Fix bug where in background-position for center keyword handling.
154 - Fix infinite loop when a wrapper element is inserted in a context
155 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
156 - Remove +x bit and shebang from index.php; only supported mode is to
157 explicitly call it with php.
158 - Make test script less chatty when log_errors is on.
160 4.1.0, released 2010-04-26
161 ! Support proprietary height attribute on table element
162 ! Support YouTube slideshows that contain /cp/ in their URL.
163 ! Support for data: URI scheme; not enabled by default, add it using
165 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
166 ! Support for Internet Explorer compatibility with %HTML.SafeObject
167 using %Output.FlashCompat.
168 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
169 - Always quote the insides of url(...) in CSS.
171 4.0.0, released 2009-07-07
172 # APIs for ConfigSchema subsystem have substantially changed. See
173 docs/dev-config-bcbreaks.txt for details; in essence, anything that
174 had both namespace and directive now have a single unified key.
175 # Some configuration directives were renamed, specifically:
176 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
177 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
178 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
179 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
180 As usual, the old directive names will still work, but will throw E_NOTICE
182 # The allowed values for class have been relaxed to allow all of CDATA for
183 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
184 %Attr.ClassUseCDATA to false.
185 # Instead of appending the content model to an old content model, a blank
186 element will replace the old content model. You can use #SUPER to get
187 the old content model.
188 ! More robust support for name="" and id=""
189 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
190 configuration, and have changes to that configuration be propagated
191 to all of its children.
192 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
193 the name attribute when set. Use with care. Thanks Ian Cook for
195 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
196 tags that contain non-breaking spaces as well other whitespace. You
197 can also modify which tags should have maintained with
198 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
199 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
200 classes users can use to a specified finite set of classes, and
201 %Attr.ForbiddenClasses, which is the logical inverse.
202 ! You can now maintain your own configuration schema directories by
203 creating a config-schema.php file or passing an extra argument. Check
204 docs/dev-config-schema.html for more details.
205 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
206 your configuration in a compact serial file, which you can unserialize
207 and use directly without having to go through the overhead of setup.
208 - Fix bug where URIDefinition would not get cleared if it's directives got
210 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
211 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
212 - Make %URI.Munge not apply to links that have the same host as your host.
213 - Prevent stray </body> tag from truncating output, if a second </body>
215 . Created script maintenance/rename-config.php for renaming a configuration
216 directive while maintaining its alias. This script does not change source code.
217 . Implement namespace locking for definition construction, to prevent
218 bugs where a directive is used for definition construction but is not
219 used to construct the cache hash.
221 3.3.0, released 2009-02-16
222 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
223 ! Implement generic property list classess
224 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
225 does not do the "right thing" with characters not supported in the output
227 - Spellcheck UTF-8: The Secret To Character Encoding
228 - Fix improper removal of the contents of elements with only whitespace. Thanks
229 Eric Wald for reporting.
230 - Fix broken test suite in versions of PHP without spl_autoload_register()
231 - Fix degenerate case with YouTube filter involving double hyphens.
232 Thanks Pierre Attar for reporting.
233 - Fix YouTube rendering problem on certain versions of Firefox.
234 - Fix CSSDefinition Printer problems with decorators
235 - Add text parameter to unit tests, forces text output
236 . Add verbose mode to command line test runner, use (--verbose)
237 . Turn on unit tests for UnitConverter
238 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
239 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
241 . Removed trailing whitespace from all text files, see
242 remote-trailing-whitespace.php maintenance script.
243 . Convert configuration to use property list backend.
245 3.2.0, released 2008-10-31
246 # Using %Core.CollectErrors forces line number/column tracking on, whereas
247 previously you could theoretically turn it off.
248 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
249 use handleEnd() instead.
250 ! %Output.AttrSort for when you need your attributes in alphabetical order to
251 deal with a bug in FCKEditor. Requested by frank farmer.
252 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
253 ! Proper support for name attribute. It is now allowed and equivalent to the id
254 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
255 is heavy (for all doctypes).
256 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
257 use on hand-written HTML.
258 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
259 the strategy to be used, standalone, on untrusted input.
260 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
261 processing of left angled brackets in smileys and other whatnot.
262 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
263 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
264 the --only-phpt parameter, although for backwards-compatibility the flag
266 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
267 Users who are not performing inbound filtering, this may seem a little
268 useless, but as a bonus, the test suite and handling of edge cases is also
270 ! Experimental implementation of forms for %HTML.Trusted
271 ! Track column numbers when maintain line numbers is on
272 ! Proprietary 'background' attribute on table-related elements converted into
273 corresponding CSS. Thanks Fusemail for sponsoring this feature!
274 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
276 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
277 time of operation varies slightly from notifyEnd() as *all* end tokens are
278 processed by the injector before they are subject to the well-formedness rules.
279 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
280 basename of image when not present.
281 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
282 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
283 the other involving an undefined $is_folder error.
284 - Throw error when %Core.Encoding is set to a spurious value. Previously,
285 this errored silently and returned false.
286 - Redirected stderr to stdout for flush error output.
287 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
289 - Do not re-munge URL if the output URL has the same host as the input URL.
291 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
292 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
293 - Fix bug with inline elements in blockquotes conflicting with strict doctype
294 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
295 - Fix bug where dots and double-dots in absolute URLs without hostname were
296 not collapsed by URIFilter_MakeAbsolute.
297 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
298 by reordering their addition.
299 - Will now throw exception on many error conditions during lexer creation; also
300 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
302 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
303 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
304 Reported by David Morton.
305 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
306 for more interesting filter-backtracking
307 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
308 index to reprocess tokens.
309 . StringHashParser now allows for multiline sections with "empty" content;
310 previously the section would remain undefined.
311 . Added --quick option to multitest.php, which tests only the most recent
312 release for each series.
313 . Added --distro option to multitest.php, which accepts either 'normal' or
314 'standalone'. This supercedes --exclude-normal and --exclude-standalone
316 3.1.1, released 2008-06-19
317 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
318 In order to enable this again, please set %URI.MungeResources to true.
319 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
320 and height/width HTML with %HTML.MaxImgLength.
321 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
322 for sponsoring this feature. Check out the corresponding documentation
323 for details. (Att Nightly testers: The API for this feature changed before
324 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
325 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
326 ! Implemented post URI filtering. Set member variable $post to true to set
328 ! Allow modules to define injectors via $info_injector. Injectors are
329 automatically disabled if injector's needed elements are not found.
330 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
331 Thanks Chris for sponsoring. If you've been using ad hoc code from the
332 forums, PLEASE use this instead.
333 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
334 embedded, tag name, attribute name, CSS property name). See %URI.Munge
335 for more details. Requested by Jochem Blok.
336 - Disable percent height/width attributes for img.
337 - AttrValidator operations are now atomic; updates to attributes are not
338 manifest in token until end of operations. This prevents naughty internal
339 code from directly modifying CurrentToken when they're not supposed to.
340 This semantics change was requested by frank farmer.
341 - Percent encoding checks enabled for URI query and fragment
342 - Fix stray backslashes in font-family; CSS Unicode character escapes are
343 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
345 - Improve parseCDATA algorithm to take into account newline normalization
346 - Account for browser confusion between Yen character and backslash in
347 Shift_JIS encoding. This fix generalizes to any other encoding which is not
348 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
349 - Fix missing configuration parameter in Generator calls. Thanks vs for the
351 - Improved adherence to Unicode by checking for non-character codepoints.
352 Thanks Geoffrey Sneddon for reporting. This may result in degraded
353 performance for extremely large inputs.
354 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
356 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
357 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
359 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
360 to __construct($min, $max). __construct(true) is equivalent to
362 . Added HTMLPurifier_AttrDef_Switch class
363 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
364 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
365 get this called with the configuration object. All modules now
366 use this rather than __construct(), although legacy code using constructors
367 will still work--the new format, however, lets modules access the
368 configuration object for HTML namespace dependant tweaks.
369 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
370 . ConfigSchema data-structure heavily optimized; on average it uses a third
371 the memory it did previously. The interface has changed accordingly,
372 consult changes to HTMLPurifier_Config for details.
373 . Variable parsing types now are magic integers instead of strings
374 . Added benchmark for ConfigSchema
375 . HTMLPurifier_Generator requires $config and $context parameters. If you
376 don't know what they should be, use HTMLPurifier_Config::createDefault()
377 and new HTMLPurifier_Context().
378 . Printers now properly distinguish between output configuration, and
379 target configuration. This is not applicable to scripts using
380 the Printers for HTML Purifier related tasks.
381 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
382 fatal errors will ensue.
383 . URIFilter->prepare can return false in order to abort loading of the filter
384 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
385 an external resource.
386 . %URI.Munge functionality factored out into a post-filter class.
387 . Added CurrentCSSProperty context variable during CSS validation
389 3.1.0, released 2008-05-18
390 # Unnecessary references to objects (vestiges of PHP4) removed from method
391 signatures. The following methods do not need references when assigning from
392 them and will result in E_STRICT errors if you try:
393 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
394 + HTMLPurifier_ConfigSchema::instance()
395 + HTMLPurifier_DefinitionCacheFactory::instance()
396 + HTMLPurifier_DefinitionCacheFactory->create()
397 + HTMLPurifier_DoctypeRegistry->register()
398 + HTMLPurifier_DoctypeRegistry->get()
399 + HTMLPurifier_HTMLModule->addElement()
400 + HTMLPurifier_HTMLModule->addBlankElement()
401 + HTMLPurifier_LanguageFactory::instance()
402 # Printer_ConfigForm's get*() functions were static-ified
403 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
404 form of tag@attr, NOT tag.attr (which will throw an error and won't do
405 anything). This is for forwards compatibility with XML; you'd do best
406 to migrate an %HTML.AllowedAttributes directives to this syntax too.
407 ! Allow index to be false for config from form creation
408 ! Added HTMLPurifier::VERSION constant
409 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
410 and allows for version numbers like "3.1.0-dev".
411 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
412 ! HTML Purifier's URI handling is a lot more robust, with much stricter
413 validation checks and better percent encoding handling. Thanks Gareth Heyes
414 for indicating security vulnerabilities from lax percent encoding.
415 ! Bootstrap autoloader deals more robustly with classes that don't exist,
416 preventing class_exists($class, true) from barfing.
417 - InterchangeBuilder now alphabetizes its lists
418 - Validation error in configdoc output fixed
419 - Iconv and other encoding errors muted even with custom error handlers that
420 do not honor error_reporting
421 - Add protection against imagecrash attack with CSS height/width
422 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
423 - Fixed and revamped broken ConfigForm smoketest
424 - Bug with bool/null fields in Printer_ConfigForm fixed
425 - Bug with global forbidden attributes fixed
426 - Improved error messages for allowed and forbidden HTML elements and attributes
427 - Missing (or null) in configdoc documentation restored
428 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
429 of DOM), HTML Purifier punts to DirectLex
430 - Fatal error with unserialization of ScriptRequired
431 - Created directories are now chmod'ed properly
432 - Fixed bug with fallback languages in LanguageFactory
433 - Standalone testing setup properly with autoload
434 . Out-of-date documentation revised
435 . UTF-8 encoding check optimization as suggested by Diego
436 . HTMLPurifier_Error removed in favor of exceptions
437 . More copy() function removed; should use clone instead
438 . More extensive unit tests for HTMLDefinition
439 . assertPurification moved to central harness
440 . HTMLPurifier_Generator accepts $config and $context parameters during
441 instantiation, not runtime
442 . Double-quotes outside of attribute values are now unescaped
444 3.1.0rc1, released 2008-04-22
445 # Autoload support added. Internal require_once's removed in favor of an
446 explicit require list or autoloading. To use HTML Purifier,
447 you must now either use HTMLPurifier.auto.php
448 or HTMLPurifier.includes.php; setting the include path and including
449 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
450 as well to register our autoload handler (or modify your autoload function
451 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
452 HTMLPurifier.safe-includes.php for a less performance friendly but more
453 user-friendly library load.
454 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
455 information is stored in the ConfigSchema directory, and the
456 maintenance/generate-schema-cache.php generates the schema.ser file, which
457 is now instantiated. Support for userland schema changes coming soon!
458 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
459 alias; to get rid of these errors just modify your configuration to use
460 the new directive name.
461 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
462 enabled using %Filter.$filter_name or by setting your own filters using
464 # Directive-level safety properties superceded in favor of module-level
465 safety. Internal method HTMLModule->addElement() has changed, although
466 the externally visible HTMLDefinition->addElement has *not* changed.
467 ! Extra utility classes for testing and non-library operations can
468 be found in extras/. Specifically, these are FSTools and ConfigDoc.
469 You may find a use for these in your own project, but right now they
470 are highly experimental and volatile.
471 ! Integration with PHPT allows for automated smoketests
