1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.6.0, unknown release date
13 # URI parsing algorithm was made more strict, so only prefixes which
14 looks like schemes will actually be schemes. Thanks
15 Michael Gusev <mgusev@sugarcrm.com> for fixing.
16 - Made Linkify URL parser a bit less permissive, so that non-breaking
17 spaces and commas are not included as part of URL. Thanks nAS for fixing.
19 4.5.0, released 2013-02-17
20 # Fix bug where stacked attribute transforms clobber each other;
21 this also means it's no longer possible to override attribute
22 transforms in later modules. No internal code was using this
23 but this may break some clients.
24 # We now use SHA-1 to identify cached definitions, instead of MD5.
25 ! Support display:inline-block
26 ! Support for more white-space CSS values.
27 ! Permit underscores in font families
28 ! Support for page-break-* CSS3 properties when proprietary properties
30 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
31 SGML excludes checking. If HTML Purifier is removing too much text
32 and you don't care about full standards compliance, try setting this to
34 - Use prepend for SPL autoloading on PHP 5.3 and later.
35 - Fix bug with nofollow transform when pre-existing rel exists.
36 - Fix bug where background:url() always gets lower-cased
37 (but not background-image:url())
38 - Fix bug with non lower-case color names in HTML
39 - Fix bug where data URI validation doesn't remove temporary files.
40 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
41 - Don't remove certain empty tags on RemoveEmpty.
43 4.4.0, released 2012-01-18
44 # Removed PEARSax3 handler.
45 # URI.Munge now munges URIs inside the same host that go from https
46 to http. Reported by Neike Taika-Tessaro.
47 # Core.EscapeNonASCIICharacters now always transforms entities to
48 entities, even if target encoding is UTF-8.
49 # Tighten up selector validation in ExtractStyleBlocks.
50 Non-syntactically valid selectors are now rejected, along with
51 some of the more obscure ones such as attribute selectors, the
52 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
53 ID and class selectors now work properly with the relevant
54 configuration attributes. Also, mute errors when parsing CSS
55 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
56 ! Added support for 'scope' attribute on tables.
57 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
58 ! Properly handle sub-lists directly nested inside of lists in
59 a standards compliant way, by moving them into the preceding <li>
60 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
61 limited allowed comments in untrusted situations.
62 ! Implement iframes, and allow them to be used in untrusted mode with
63 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
64 <brad.froehle@gmail.com> for submitting an initial version of the patch.
65 ! The Forms module now works properly for transitional doctypes.
66 ! Added support for internationalized domain names. You need the PEAR
67 Net_IDNA2 module to be in your path; if it is installed, ensure the
68 class can be loaded and then set %Core.EnableIDNA to true.
69 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
70 <yramirez-htmlpurifier@adicio.com> for reporting.
71 - Explicitly initialize anonModule variable to null.
72 - Do not duplicate nofollow if already present. Thanks 178
74 - Do not add nofollow if hostname matches our current host. Thanks 178
75 for reporting, and Neike Taika-Tessaro for helping diagnose.
76 - Do not unset parser variable; this fixes intermittent serialization
77 problems. Thanks Neike Taika-Tessaro for reporting, bill
78 <10010tiger@gmail.com> for diagnosing.
79 - Fix iconv truncation bug, where non-UTF-8 target encodings see
80 output truncated after around 8000 characters. Thanks Jörg Ludwig
81 <joerg.ludwig@iserv.eu> for reporting.
82 - Fix broken table content model for XHTML1.1 (and also earlier
83 versions, although the W3C validator doesn't catch those violations).
84 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
86 4.3.0, released 2011-03-27
87 # Fixed broken caching of customized raw definitions, but requires an
88 API change. The old API still works but will emit a warning,
89 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
90 for how to upgrade your code.
91 # Protect against Internet Explorer innerHTML behavior by specially
92 treating attributes with backticks but no angled brackets, quotes or
93 spaces. This constitutes a slight semantic change, which can be
94 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
96 # Protect against cssText/innerHTML by restricting allowed characters
97 used in fonts further than mandated by the specification and encoding
98 some extra special characters in URLs. Reported by Neike
99 Taika-Tessaro and Mario Heiderich.
100 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
101 ! More types of SPL autoloaders allowed on later versions of PHP.
102 ! Implementations for position, top, left, right, bottom, z-index
103 when %CSS.Trusted is on.
104 ! Add %Cache.SerializerPermissions option for custom serializer
105 directory/file permissions
106 ! Fix longstanding bug in Flash support for non-IE browsers, and
107 allow more wmode attributes.
108 ! Add %CSS.AllowedFonts to restrict permissible font names.
109 - Switch to an iterative traversal of the DOM, which prevents us
110 from running out of stack space for deeply nested documents.
111 Thanks Maxim Krizhanovsky for contributing a patch.
112 - Make removal of conditional IE comments ungreedy; thanks Bernd
114 - Escape CDATA before removing Internet Explorer comments.
115 - Fix removal of id attributes under certain conditions by ensuring
116 armor attributes are preserved when recreating tags.
117 - Check if schema.ser was corrupted.
118 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
119 This safety check is only done for HTMLPurifier.auto.php; if you
120 are using standalone or the specialized includes files, you're
121 expected to know what you're doing.
122 - Stop repeatedly writing the cache file after I'm done customizing a
123 raw definition. Reported by ajh.
124 - Switch to using require_once in the Bootstrap to work around bad
125 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
126 - Fix URI handling when hostname is missing but scheme is present.
127 Reported by Neike Taika-Tessaro.
128 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
130 - Fix harmless notice from indexing into empty string. Thanks Matthijs
131 Kooijman <matthijs@stdin.nl> for reporting.
132 - Don't autoclose no parent elements are able to support the element
133 that triggered the autoclose. In particular fixes strange behavior
134 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
135 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
137 4.2.0, released 2010-09-15
138 ! Added %Core.RemoveProcessingInstructions, which lets you remove
139 <? ... ?> statements.
140 ! Added %URI.DisableResources functionality; the directive originally
141 did nothing. Thanks David Rothstein for reporting.
142 ! Add documentation about configuration directive types.
143 ! Add %CSS.ForbiddenProperties configuration directive.
144 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
145 to utilize full-screen mode.
146 ! Add optional support for the <code>file</code> URI scheme, enable
147 by explicitly setting %URI.AllowedSchemes.
148 ! Add %Core.NormalizeNewlines options to allow turning off newline
150 - Fix improper handling of Internet Explorer conditional comments
151 by parser. Thanks zmonteca for reporting.
152 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
153 Thanks sidepodcast for the fix.
154 - Warn if an element is allowed, but an attribute it requires is
157 4.1.1, released 2010-05-31
158 - Fix undefined index warnings in maintenance scripts.
159 - Fix bug in DirectLex for parsing elements with a single attribute
161 - Rewrite CSS output logic for font-family and url(). Thanks Mario
162 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
163 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
164 - Emit an error for CollectErrors if a body is extracted
165 - Fix bug where in background-position for center keyword handling.
166 - Fix infinite loop when a wrapper element is inserted in a context
167 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
168 - Remove +x bit and shebang from index.php; only supported mode is to
169 explicitly call it with php.
170 - Make test script less chatty when log_errors is on.
172 4.1.0, released 2010-04-26
173 ! Support proprietary height attribute on table element
174 ! Support YouTube slideshows that contain /cp/ in their URL.
175 ! Support for data: URI scheme; not enabled by default, add it using
177 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
178 ! Support for Internet Explorer compatibility with %HTML.SafeObject
179 using %Output.FlashCompat.
180 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
181 - Always quote the insides of url(...) in CSS.
183 4.0.0, released 2009-07-07
184 # APIs for ConfigSchema subsystem have substantially changed. See
185 docs/dev-config-bcbreaks.txt for details; in essence, anything that
186 had both namespace and directive now have a single unified key.
187 # Some configuration directives were renamed, specifically:
188 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
189 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
190 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
191 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
192 As usual, the old directive names will still work, but will throw E_NOTICE
194 # The allowed values for class have been relaxed to allow all of CDATA for
195 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
196 %Attr.ClassUseCDATA to false.
197 # Instead of appending the content model to an old content model, a blank
198 element will replace the old content model. You can use #SUPER to get
199 the old content model.
200 ! More robust support for name="" and id=""
201 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
202 configuration, and have changes to that configuration be propagated
203 to all of its children.
204 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
205 the name attribute when set. Use with care. Thanks Ian Cook for
207 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
208 tags that contain non-breaking spaces as well other whitespace. You
209 can also modify which tags should have maintained with
210 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
211 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
212 classes users can use to a specified finite set of classes, and
213 %Attr.ForbiddenClasses, which is the logical inverse.
214 ! You can now maintain your own configuration schema directories by
215 creating a config-schema.php file or passing an extra argument. Check
216 docs/dev-config-schema.html for more details.
217 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
218 your configuration in a compact serial file, which you can unserialize
219 and use directly without having to go through the overhead of setup.
220 - Fix bug where URIDefinition would not get cleared if it's directives got
222 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
223 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
224 - Make %URI.Munge not apply to links that have the same host as your host.
225 - Prevent stray </body> tag from truncating output, if a second </body>
227 . Created script maintenance/rename-config.php for renaming a configuration
228 directive while maintaining its alias. This script does not change source code.
229 . Implement namespace locking for definition construction, to prevent
230 bugs where a directive is used for definition construction but is not
231 used to construct the cache hash.
233 3.3.0, released 2009-02-16
234 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
235 ! Implement generic property list classess
236 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
237 does not do the "right thing" with characters not supported in the output
239 - Spellcheck UTF-8: The Secret To Character Encoding
240 - Fix improper removal of the contents of elements with only whitespace. Thanks
241 Eric Wald for reporting.
242 - Fix broken test suite in versions of PHP without spl_autoload_register()
243 - Fix degenerate case with YouTube filter involving double hyphens.
244 Thanks Pierre Attar for reporting.
245 - Fix YouTube rendering problem on certain versions of Firefox.
246 - Fix CSSDefinition Printer problems with decorators
247 - Add text parameter to unit tests, forces text output
248 . Add verbose mode to command line test runner, use (--verbose)
249 . Turn on unit tests for UnitConverter
250 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
251 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
253 . Removed trailing whitespace from all text files, see
254 remote-trailing-whitespace.php maintenance script.
255 . Convert configuration to use property list backend.
257 3.2.0, released 2008-10-31
258 # Using %Core.CollectErrors forces line number/column tracking on, whereas
259 previously you could theoretically turn it off.
260 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
261 use handleEnd() instead.
262 ! %Output.AttrSort for when you need your attributes in alphabetical order to
263 deal with a bug in FCKEditor. Requested by frank farmer.
264 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
265 ! Proper support for name attribute. It is now allowed and equivalent to the id
266 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
267 is heavy (for all doctypes).
268 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
269 use on hand-written HTML.
270 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
271 the strategy to be used, standalone, on untrusted input.
272 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
273 processing of left angled brackets in smileys and other whatnot.
274 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
275 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
276 the --only-phpt parameter, although for backwards-compatibility the flag
278 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
279 Users who are not performing inbound filtering, this may seem a little
280 useless, but as a bonus, the test suite and handling of edge cases is also
282 ! Experimental implementation of forms for %HTML.Trusted
283 ! Track column numbers when maintain line numbers is on
284 ! Proprietary 'background' attribute on table-related elements converted into
285 corresponding CSS. Thanks Fusemail for sponsoring this feature!
286 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
288 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
289 time of operation varies slightly from notifyEnd() as *all* end tokens are
290 processed by the injector before they are subject to the well-formedness rules.
291 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
292 basename of image when not present.
293 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
294 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
295 the other involving an undefined $is_folder error.
296 - Throw error when %Core.Encoding is set to a spurious value. Previously,
297 this errored silently and returned false.
298 - Redirected stderr to stdout for flush error output.
299 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
301 - Do not re-munge URL if the output URL has the same host as the input URL.
303 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
304 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
305 - Fix bug with inline elements in blockquotes conflicting with strict doctype
306 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
307 - Fix bug where dots and double-dots in absolute URLs without hostname were
308 not collapsed by URIFilter_MakeAbsolute.
309 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
310 by reordering their addition.
311 - Will now throw exception on many error conditions during lexer creation; also
312 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
314 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
315 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
316 Reported by David Morton.
317 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
318 for more interesting filter-backtracking
319 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
320 index to reprocess tokens.
321 . StringHashParser now allows for multiline sections with "empty" content;
322 previously the section would remain undefined.
323 . Added --quick option to multitest.php, which tests only the most recent
324 release for each series.
325 . Added --distro option to multitest.php, which accepts either 'normal' or
326 'standalone'. This supercedes --exclude-normal and --exclude-standalone
328 3.1.1, released 2008-06-19
329 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
330 In order to enable this again, please set %URI.MungeResources to true.
331 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
332 and height/width HTML with %HTML.MaxImgLength.
333 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
334 for sponsoring this feature. Check out the corresponding documentation
335 for details. (Att Nightly testers: The API for this feature changed before
336 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
337 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
338 ! Implemented post URI filtering. Set member variable $post to true to set
340 ! Allow modules to define injectors via $info_injector. Injectors are
341 automatically disabled if injector's needed elements are not found.
342 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
343 Thanks Chris for sponsoring. If you've been using ad hoc code from the
344 forums, PLEASE use this instead.
345 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
346 embedded, tag name, attribute name, CSS property name). See %URI.Munge
347 for more details. Requested by Jochem Blok.
348 - Disable percent height/width attributes for img.
349 - AttrValidator operations are now atomic; updates to attributes are not
350 manifest in token until end of operations. This prevents naughty internal
351 code from directly modifying CurrentToken when they're not supposed to.
352 This semantics change was requested by frank farmer.
353 - Percent encoding checks enabled for URI query and fragment
354 - Fix stray backslashes in font-family; CSS Unicode character escapes are
355 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
357 - Improve parseCDATA algorithm to take into account newline normalization
358 - Account for browser confusion between Yen character and backslash in
359 Shift_JIS encoding. This fix generalizes to any other encoding which is not
360 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
361 - Fix missing configuration parameter in Generator calls. Thanks vs for the
363 - Improved adherence to Unicode by checking for non-character codepoints.
364 Thanks Geoffrey Sneddon for reporting. This may result in degraded
365 performance for extremely large inputs.
366 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
368 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
369 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
371 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
372 to __construct($min, $max). __construct(true) is equivalent to
374 . Added HTMLPurifier_AttrDef_Switch class
375 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
376 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
377 get this called with the configuration object. All modules now
378 use this rather than __construct(), although legacy code using constructors
379 will still work--the new format, however, lets modules access the
380 configuration object for HTML namespace dependant tweaks.
381 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
382 . ConfigSchema data-structure heavily optimized; on average it uses a third
383 the memory it did previously. The interface has changed accordingly,
384 consult changes to HTMLPurifier_Config for details.
385 . Variable parsing types now are magic integers instead of strings
386 . Added benchmark for ConfigSchema
387 . HTMLPurifier_Generator requires $config and $context parameters. If you
388 don't know what they should be, use HTMLPurifier_Config::createDefault()
389 and new HTMLPurifier_Context().
390 . Printers now properly distinguish between output configuration, and
391 target configuration. This is not applicable to scripts using
392 the Printers for HTML Purifier related tasks.
393 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
394 fatal errors will ensue.
395 . URIFilter->prepare can return false in order to abort loading of the filter
396 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
397 an external resource.
398 . %URI.Munge functionality factored out into a post-filter class.
399 . Added CurrentCSSProperty context variable during CSS validation
401 3.1.0, released 2008-05-18
402 # Unnecessary references to objects (vestiges of PHP4) removed from method
403 signatures. The following methods do not need references when assigning from
404 them and will result in E_STRICT errors if you try:
405 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
406 + HTMLPurifier_ConfigSchema::instance()
407 + HTMLPurifier_DefinitionCacheFactory::instance()
408 + HTMLPurifier_DefinitionCacheFactory->create()
409 + HTMLPurifier_DoctypeRegistry->register()
410 + HTMLPurifier_DoctypeRegistry->get()
411 + HTMLPurifier_HTMLModule->addElement()
412 + HTMLPurifier_HTMLModule->addBlankElement()
413 + HTMLPurifier_LanguageFactory::instance()
414 # Printer_ConfigForm's get*() functions were static-ified
415 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
416 form of tag@attr, NOT tag.attr (which will throw an error and won't do
417 anything). This is for forwards compatibility with XML; you'd do best
418 to migrate an %HTML.AllowedAttributes directives to this syntax too.
419 ! Allow index to be false for config from form creation
420 ! Added HTMLPurifier::VERSION constant
421 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
422 and allows for version numbers like "3.1.0-dev".
423 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
424 ! HTML Purifier's URI handling is a lot more robust, with much stricter
425 validation checks and better percent encoding handling. Thanks Gareth Heyes
426 for indicating security vulnerabilities from lax percent encoding.
427 ! Bootstrap autoloader deals more robustly with classes that don't exist,
428 preventing class_exists($class, true) from barfing.
429 - InterchangeBuilder now alphabetizes its lists
430 - Validation error in configdoc output fixed
431 - Iconv and other encoding errors muted even with custom error handlers that
432 do not honor error_reporting
433 - Add protection against imagecrash attack with CSS height/width
434 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
435 - Fixed and revamped broken ConfigForm smoketest
436 - Bug with bool/null fields in Printer_ConfigForm fixed
437 - Bug with global forbidden attributes fixed
438 - Improved error messages for allowed and forbidden HTML elements and attributes
439 - Missing (or null) in configdoc documentation restored
440 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
441 of DOM), HTML Purifier punts to DirectLex
442 - Fatal error with unserialization of ScriptRequired
443 - Created directories are now chmod'ed properly
444 - Fixed bug with fallback languages in LanguageFactory
445 - Standalone testing setup properly with autoload
446 . Out-of-date documentation revised
447 . UTF-8 encoding check optimization as suggested by Diego
448 . HTMLPurifier_Error removed in favor of exceptions
449 . More copy() function removed; should use clone instead
450 . More extensive unit tests for HTMLDefinition
451 . assertPurification moved to central harness
452 . HTMLPurifier_Generator accepts $config and $context parameters during
453 instantiation, not runtime
454 . Double-quotes outside of attribute values are now unescaped
456 3.1.0rc1, released 2008-04-22
457 # Autoload support added. Internal require_once's removed in favor of an
458 explicit require list or autoloading. To use HTML Purifier,
459 you must now either use HTMLPurifier.auto.php
460 or HTMLPurifier.includes.php; setting the include path and including
461 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
462 as well to register our autoload handler (or modify your autoload function
463 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
464 HTMLPurifier.safe-includes.php for a less performance friendly but more
465 user-friendly library load.
466 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
467 information is stored in the ConfigSchema directory, and the
468 maintenance/generate-schema-cache.php generates the schema.ser file, which
469 is now instantiated. Support for userland schema changes coming soon!
470 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
471 alias; to get rid of these errors just modify your configuration to use
