4 = KEY ====================
10 ==========================
12 4.5.0, released 2013-02-17
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 # We now use SHA-1 to identify cached definitions, instead of MD5.
18 ! Support display:inline-block
19 ! Support for more white-space CSS values.
20 ! Permit underscores in font families
21 ! Support for page-break-* CSS3 properties when proprietary properties
23 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
24 SGML excludes checking. If HTML Purifier is removing too much text
25 and you don't care about full standards compliance, try setting this to
27 - Use prepend for SPL autoloading on PHP 5.3 and later.
28 - Fix bug with nofollow transform when pre-existing rel exists.
29 - Fix bug where background:url() always gets lower-cased
30 (but not background-image:url())
31 - Fix bug with non lower-case color names in HTML
32 - Fix bug where data URI validation doesn't remove temporary files.
33 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
34 - Don't remove certain empty tags on RemoveEmpty.
36 4.4.0, released 2012-01-18
37 # Removed PEARSax3 handler.
38 # URI.Munge now munges URIs inside the same host that go from https
39 to http. Reported by Neike Taika-Tessaro.
40 # Core.EscapeNonASCIICharacters now always transforms entities to
41 entities, even if target encoding is UTF-8.
42 # Tighten up selector validation in ExtractStyleBlocks.
43 Non-syntactically valid selectors are now rejected, along with
44 some of the more obscure ones such as attribute selectors, the
45 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
46 ID and class selectors now work properly with the relevant
47 configuration attributes. Also, mute errors when parsing CSS
48 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
49 ! Added support for 'scope' attribute on tables.
50 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
51 ! Properly handle sub-lists directly nested inside of lists in
52 a standards compliant way, by moving them into the preceding <li>
53 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
54 limited allowed comments in untrusted situations.
55 ! Implement iframes, and allow them to be used in untrusted mode with
56 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
57 <brad.froehle@gmail.com> for submitting an initial version of the patch.
58 ! The Forms module now works properly for transitional doctypes.
59 ! Added support for internationalized domain names. You need the PEAR
60 Net_IDNA2 module to be in your path; if it is installed, ensure the
61 class can be loaded and then set %Core.EnableIDNA to true.
62 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
63 <yramirez-htmlpurifier@adicio.com> for reporting.
64 - Explicitly initialize anonModule variable to null.
65 - Do not duplicate nofollow if already present. Thanks 178
67 - Do not add nofollow if hostname matches our current host. Thanks 178
68 for reporting, and Neike Taika-Tessaro for helping diagnose.
69 - Do not unset parser variable; this fixes intermittent serialization
70 problems. Thanks Neike Taika-Tessaro for reporting, bill
71 <10010tiger@gmail.com> for diagnosing.
72 - Fix iconv truncation bug, where non-UTF-8 target encodings see
73 output truncated after around 8000 characters. Thanks Jörg Ludwig
74 <joerg.ludwig@iserv.eu> for reporting.
75 - Fix broken table content model for XHTML1.1 (and also earlier
76 versions, although the W3C validator doesn't catch those violations).
77 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
79 4.3.0, released 2011-03-27
80 # Fixed broken caching of customized raw definitions, but requires an
81 API change. The old API still works but will emit a warning,
82 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
83 for how to upgrade your code.
84 # Protect against Internet Explorer innerHTML behavior by specially
85 treating attributes with backticks but no angled brackets, quotes or
86 spaces. This constitutes a slight semantic change, which can be
87 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
89 # Protect against cssText/innerHTML by restricting allowed characters
90 used in fonts further than mandated by the specification and encoding
91 some extra special characters in URLs. Reported by Neike
92 Taika-Tessaro and Mario Heiderich.
93 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
94 ! More types of SPL autoloaders allowed on later versions of PHP.
95 ! Implementations for position, top, left, right, bottom, z-index
96 when %CSS.Trusted is on.
97 ! Add %Cache.SerializerPermissions option for custom serializer
98 directory/file permissions
99 ! Fix longstanding bug in Flash support for non-IE browsers, and
100 allow more wmode attributes.
101 ! Add %CSS.AllowedFonts to restrict permissible font names.
102 - Switch to an iterative traversal of the DOM, which prevents us
103 from running out of stack space for deeply nested documents.
104 Thanks Maxim Krizhanovsky for contributing a patch.
105 - Make removal of conditional IE comments ungreedy; thanks Bernd
107 - Escape CDATA before removing Internet Explorer comments.
108 - Fix removal of id attributes under certain conditions by ensuring
109 armor attributes are preserved when recreating tags.
110 - Check if schema.ser was corrupted.
111 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
112 This safety check is only done for HTMLPurifier.auto.php; if you
113 are using standalone or the specialized includes files, you're
114 expected to know what you're doing.
115 - Stop repeatedly writing the cache file after I'm done customizing a
116 raw definition. Reported by ajh.
117 - Switch to using require_once in the Bootstrap to work around bad
118 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
119 - Fix URI handling when hostname is missing but scheme is present.
120 Reported by Neike Taika-Tessaro.
121 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
123 - Fix harmless notice from indexing into empty string. Thanks Matthijs
124 Kooijman <matthijs@stdin.nl> for reporting.
125 - Don't autoclose no parent elements are able to support the element
126 that triggered the autoclose. In particular fixes strange behavior
127 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
128 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
130 4.2.0, released 2010-09-15
131 ! Added %Core.RemoveProcessingInstructions, which lets you remove
132 <? ... ?> statements.
133 ! Added %URI.DisableResources functionality; the directive originally
134 did nothing. Thanks David Rothstein for reporting.
135 ! Add documentation about configuration directive types.
136 ! Add %CSS.ForbiddenProperties configuration directive.
137 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
138 to utilize full-screen mode.
139 ! Add optional support for the <code>file</code> URI scheme, enable
140 by explicitly setting %URI.AllowedSchemes.
141 ! Add %Core.NormalizeNewlines options to allow turning off newline
143 - Fix improper handling of Internet Explorer conditional comments
144 by parser. Thanks zmonteca for reporting.
145 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
146 Thanks sidepodcast for the fix.
147 - Warn if an element is allowed, but an attribute it requires is
150 4.1.1, released 2010-05-31
151 - Fix undefined index warnings in maintenance scripts.
152 - Fix bug in DirectLex for parsing elements with a single attribute
154 - Rewrite CSS output logic for font-family and url(). Thanks Mario
155 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
156 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
157 - Emit an error for CollectErrors if a body is extracted
158 - Fix bug where in background-position for center keyword handling.
159 - Fix infinite loop when a wrapper element is inserted in a context
160 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
161 - Remove +x bit and shebang from index.php; only supported mode is to
162 explicitly call it with php.
163 - Make test script less chatty when log_errors is on.
165 4.1.0, released 2010-04-26
166 ! Support proprietary height attribute on table element
167 ! Support YouTube slideshows that contain /cp/ in their URL.
168 ! Support for data: URI scheme; not enabled by default, add it using
170 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
171 ! Support for Internet Explorer compatibility with %HTML.SafeObject
172 using %Output.FlashCompat.
173 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
174 - Always quote the insides of url(...) in CSS.
176 4.0.0, released 2009-07-07
177 # APIs for ConfigSchema subsystem have substantially changed. See
178 docs/dev-config-bcbreaks.txt for details; in essence, anything that
179 had both namespace and directive now have a single unified key.
180 # Some configuration directives were renamed, specifically:
181 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
182 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
183 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
184 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
185 As usual, the old directive names will still work, but will throw E_NOTICE
187 # The allowed values for class have been relaxed to allow all of CDATA for
188 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
189 %Attr.ClassUseCDATA to false.
190 # Instead of appending the content model to an old content model, a blank
191 element will replace the old content model. You can use #SUPER to get
192 the old content model.
193 ! More robust support for name="" and id=""
194 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
195 configuration, and have changes to that configuration be propagated
196 to all of its children.
197 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
198 the name attribute when set. Use with care. Thanks Ian Cook for
200 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
201 tags that contain non-breaking spaces as well other whitespace. You
202 can also modify which tags should have maintained with
203 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
204 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
205 classes users can use to a specified finite set of classes, and
206 %Attr.ForbiddenClasses, which is the logical inverse.
207 ! You can now maintain your own configuration schema directories by
208 creating a config-schema.php file or passing an extra argument. Check
209 docs/dev-config-schema.html for more details.
210 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
211 your configuration in a compact serial file, which you can unserialize
212 and use directly without having to go through the overhead of setup.
213 - Fix bug where URIDefinition would not get cleared if it's directives got
215 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
216 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
217 - Make %URI.Munge not apply to links that have the same host as your host.
218 - Prevent stray </body> tag from truncating output, if a second </body>
220 . Created script maintenance/rename-config.php for renaming a configuration
221 directive while maintaining its alias. This script does not change source code.
222 . Implement namespace locking for definition construction, to prevent
223 bugs where a directive is used for definition construction but is not
224 used to construct the cache hash.
226 3.3.0, released 2009-02-16
227 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
228 ! Implement generic property list classess
229 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
230 does not do the "right thing" with characters not supported in the output
232 - Spellcheck UTF-8: The Secret To Character Encoding
233 - Fix improper removal of the contents of elements with only whitespace. Thanks
234 Eric Wald for reporting.
235 - Fix broken test suite in versions of PHP without spl_autoload_register()
236 - Fix degenerate case with YouTube filter involving double hyphens.
237 Thanks Pierre Attar for reporting.
238 - Fix YouTube rendering problem on certain versions of Firefox.
239 - Fix CSSDefinition Printer problems with decorators
240 - Add text parameter to unit tests, forces text output
241 . Add verbose mode to command line test runner, use (--verbose)
242 . Turn on unit tests for UnitConverter
243 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
244 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
246 . Removed trailing whitespace from all text files, see
247 remote-trailing-whitespace.php maintenance script.
248 . Convert configuration to use property list backend.
250 3.2.0, released 2008-10-31
251 # Using %Core.CollectErrors forces line number/column tracking on, whereas
252 previously you could theoretically turn it off.
253 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
254 use handleEnd() instead.
255 ! %Output.AttrSort for when you need your attributes in alphabetical order to
256 deal with a bug in FCKEditor. Requested by frank farmer.
257 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
258 ! Proper support for name attribute. It is now allowed and equivalent to the id
259 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
260 is heavy (for all doctypes).
261 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
262 use on hand-written HTML.
263 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
264 the strategy to be used, standalone, on untrusted input.
265 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
266 processing of left angled brackets in smileys and other whatnot.
267 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
268 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
269 the --only-phpt parameter, although for backwards-compatibility the flag
271 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
272 Users who are not performing inbound filtering, this may seem a little
273 useless, but as a bonus, the test suite and handling of edge cases is also
275 ! Experimental implementation of forms for %HTML.Trusted
276 ! Track column numbers when maintain line numbers is on
277 ! Proprietary 'background' attribute on table-related elements converted into
278 corresponding CSS. Thanks Fusemail for sponsoring this feature!
279 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
281 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
282 time of operation varies slightly from notifyEnd() as *all* end tokens are
283 processed by the injector before they are subject to the well-formedness rules.
284 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
285 basename of image when not present.
286 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
287 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
288 the other involving an undefined $is_folder error.
289 - Throw error when %Core.Encoding is set to a spurious value. Previously,
290 this errored silently and returned false.
291 - Redirected stderr to stdout for flush error output.
292 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
294 - Do not re-munge URL if the output URL has the same host as the input URL.
296 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
297 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
298 - Fix bug with inline elements in blockquotes conflicting with strict doctype
299 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
300 - Fix bug where dots and double-dots in absolute URLs without hostname were
301 not collapsed by URIFilter_MakeAbsolute.
302 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
303 by reordering their addition.
304 - Will now throw exception on many error conditions during lexer creation; also
305 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
307 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
308 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
309 Reported by David Morton.
310 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
311 for more interesting filter-backtracking
312 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
313 index to reprocess tokens.
314 . StringHashParser now allows for multiline sections with "empty" content;
315 previously the section would remain undefined.
316 . Added --quick option to multitest.php, which tests only the most recent
317 release for each series.
318 . Added --distro option to multitest.php, which accepts either 'normal' or
319 'standalone'. This supercedes --exclude-normal and --exclude-standalone
321 3.1.1, released 2008-06-19
322 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
323 In order to enable this again, please set %URI.MungeResources to true.
324 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
325 and height/width HTML with %HTML.MaxImgLength.
326 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
327 for sponsoring this feature. Check out the corresponding documentation
328 for details. (Att Nightly testers: The API for this feature changed before
329 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
330 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
331 ! Implemented post URI filtering. Set member variable $post to true to set
333 ! Allow modules to define injectors via $info_injector. Injectors are
334 automatically disabled if injector's needed elements are not found.
335 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
336 Thanks Chris for sponsoring. If you've been using ad hoc code from the
337 forums, PLEASE use this instead.
338 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
339 embedded, tag name, attribute name, CSS property name). See %URI.Munge
340 for more details. Requested by Jochem Blok.
341 - Disable percent height/width attributes for img.
342 - AttrValidator operations are now atomic; updates to attributes are not
343 manifest in token until end of operations. This prevents naughty internal
344 code from directly modifying CurrentToken when they're not supposed to.
345 This semantics change was requested by frank farmer.
346 - Percent encoding checks enabled for URI query and fragment
347 - Fix stray backslashes in font-family; CSS Unicode character escapes are
348 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
350 - Improve parseCDATA algorithm to take into account newline normalization
351 - Account for browser confusion between Yen character and backslash in
352 Shift_JIS encoding. This fix generalizes to any other encoding which is not
353 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
354 - Fix missing configuration parameter in Generator calls. Thanks vs for the
356 - Improved adherence to Unicode by checking for non-character codepoints.
357 Thanks Geoffrey Sneddon for reporting. This may result in degraded
358 performance for extremely large inputs.
359 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
361 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
362 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
364 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
365 to __construct($min, $max). __construct(true) is equivalent to
367 . Added HTMLPurifier_AttrDef_Switch class
368 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
369 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
370 get this called with the configuration object. All modules now
371 use this rather than __construct(), although legacy code using constructors
372 will still work--the new format, however, lets modules access the
373 configuration object for HTML namespace dependant tweaks.
374 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
375 . ConfigSchema data-structure heavily optimized; on average it uses a third
376 the memory it did previously. The interface has changed accordingly,
377 consult changes to HTMLPurifier_Config for details.
378 . Variable parsing types now are magic integers instead of strings
379 . Added benchmark for ConfigSchema
380 . HTMLPurifier_Generator requires $config and $context parameters. If you
381 don't know what they should be, use HTMLPurifier_Config::createDefault()
382 and new HTMLPurifier_Context().
383 . Printers now properly distinguish between output configuration, and
384 target configuration. This is not applicable to scripts using
385 the Printers for HTML Purifier related tasks.
386 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
387 fatal errors will ensue.
388 . URIFilter->prepare can return false in order to abort loading of the filter
389 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
390 an external resource.
391 . %URI.Munge functionality factored out into a post-filter class.
392 . Added CurrentCSSProperty context variable during CSS validation
394 3.1.0, released 2008-05-18
395 # Unnecessary references to objects (vestiges of PHP4) removed from method
396 signatures. The following methods do not need references when assigning from
397 them and will result in E_STRICT errors if you try:
398 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
399 + HTMLPurifier_ConfigSchema::instance()
400 + HTMLPurifier_DefinitionCacheFactory::instance()
401 + HTMLPurifier_DefinitionCacheFactory->create()
402 + HTMLPurifier_DoctypeRegistry->register()
403 + HTMLPurifier_DoctypeRegistry->get()
404 + HTMLPurifier_HTMLModule->addElement()
405 + HTMLPurifier_HTMLModule->addBlankElement()
406 + HTMLPurifier_LanguageFactory::instance()
407 # Printer_ConfigForm's get*() functions were static-ified
408 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
409 form of tag@attr, NOT tag.attr (which will throw an error and won't do
410 anything). This is for forwards compatibility with XML; you'd do best
411 to migrate an %HTML.AllowedAttributes directives to this syntax too.
412 ! Allow index to be false for config from form creation
413 ! Added HTMLPurifier::VERSION constant
414 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
415 and allows for version numbers like "3.1.0-dev".
416 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
417 ! HTML Purifier's URI handling is a lot more robust, with much stricter
418 validation checks and better percent encoding handling. Thanks Gareth Heyes
419 for indicating security vulnerabilities from lax percent encoding.
420 ! Bootstrap autoloader deals more robustly with classes that don't exist,
421 preventing class_exists($class, true) from barfing.
422 - InterchangeBuilder now alphabetizes its lists
423 - Validation error in configdoc output fixed
424 - Iconv and other encoding errors muted even with custom error handlers that
425 do not honor error_reporting
426 - Add protection against imagecrash attack with CSS height/width
427 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
428 - Fixed and revamped broken ConfigForm smoketest
429 - Bug with bool/null fields in Printer_ConfigForm fixed
430 - Bug with global forbidden attributes fixed
431 - Improved error messages for allowed and forbidden HTML elements and attributes
432 - Missing (or null) in configdoc documentation restored
433 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
434 of DOM), HTML Purifier punts to DirectLex
435 - Fatal error with unserialization of ScriptRequired
436 - Created directories are now chmod'ed properly
437 - Fixed bug with fallback languages in LanguageFactory
438 - Standalone testing setup properly with autoload
439 . Out-of-date documentation revised
440 . UTF-8 encoding check optimization as suggested by Diego
441 . HTMLPurifier_Error removed in favor of exceptions
442 . More copy() function removed; should use clone instead
443 . More extensive unit tests for HTMLDefinition
444 . assertPurification moved to central harness
445 . HTMLPurifier_Generator accepts $config and $context parameters during
446 instantiation, not runtime
447 . Double-quotes outside of attribute values are now unescaped
449 3.1.0rc1, released 2008-04-22
450 # Autoload support added. Internal require_once's removed in favor of an
451 explicit require list or autoloading. To use HTML Purifier,
452 you must now either use HTMLPurifier.auto.php
453 or HTMLPurifier.includes.php; setting the include path and including
454 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
455 as well to register our autoload handler (or modify your autoload function
456 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
457 HTMLPurifier.safe-includes.php for a less performance friendly but more
458 user-friendly library load.
459 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
460 information is stored in the ConfigSchema directory, and the
461 maintenance/generate-schema-cache.php generates the schema.ser file, which
462 is now instantiated. Support for userland schema changes coming soon!
463 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
464 alias; to get rid of these errors just modify your configuration to use
465 the new directive name.
466 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
467 enabled using %Filter.$filter_name or by setting your own filters using
469 # Directive-level safety properties superceded in favor of module-level
470 safety. Internal method HTMLModule->addElement() has changed, although
471 the externally visible HTMLDefinition->addElement has *not* changed.
472 ! Extra utility classes for testing and non-library operations can
