1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
5 # Breaks back-compat
6 ! Feature
7 - Bugfix
8 + Sub-comment
9 . Internal change
10 ==========================
12 4.9.0, unknown release date
13 ! %URI.DefaultScheme can now be set to null, in which case
14 all relative paths are removed.
15 ! New CSS properties: min-width, max-width, min-height, max-height (#94)
16 ! Transparency (rgba) and hsl/hsla supported where color CSS is present.
17 Thanks @fxbt for contributing the patch. (#118)
18 - When idn_to_ascii is defined, we might accept malformed
19 hostnames. Apply validation to the result in such cases.
20 - Close directory when done in Serializer DefinitionCache (#100)
21 - Deleted some asserts to avoid linters from choking (#97)
22 - Rework Serializer cache behavior to avoid chmod'ing if possible (#32)
23 - Embedded semicolons in strings in CSS are now handled correctly!
24 - We accidentally dropped certain Unicode characters if there was
25 one or more invalid characters. This has been fixed, thanks
26 to mpyw <ryosuke_i_628@yahoo.co.jp>
27 - Fix for "Don't truncate upon encountering </div> when using DOMLex"
28 caused a regression with HTML 4.01 Strict parsing with libxml 2.9.1
29 (and maybe later versions, but known OK with libxml 2.9.4). The
30 fix is to go about handling truncation a bit more cleverly so that
31 we can wrap with divs (sidestepping the bug) but slurping out the
32 rest of the text in case it ran off the end. (#78)
33 # By default, when a link has a target attribute associated
34 with it, we now also add rel="noopener" in order to
35 prevent the new window from being able to overwrite
36 the original frame. To disable this protection,
37 set %HTML.TargetNoopener to FALSE.
39 4.8.0, released 2016-07-16
40 # By default, when a link has a target attribute associated
41 with it, we now also add rel="noreferrer" in order to
42 prevent the new window from being able to overwrite
43 the original frame. To disable this protection,
44 set %HTML.TargetNoreferrer to FALSE.
45 ! Full PHP 7 compatibility, the test suite is ALL GO.
46 ! %CSS.AllowDuplicates permits duplicate CSS properties.
47 ! Support for 'tel' URIs.
48 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
49 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
50 yet supported.
51 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
52 - alt truncation could result in malformed UTF-8 sequence. Don't
53 truncate. Thanks Brandon Farber for reporting.
54 - Linkify regex is smarter, based off of Gruber's regex.
55 - IDNA supported natively on PHP 5.3 and later.
56 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
57 allowed.
58 - Minor bounds error fix to squash a PHP 7 notice.
59 - Support non-/tmp temporary directories for data:// validation
60 - Give a better error message when a user attempts to allow
61 ul/ol without allowing li.
62 - On some versions of PHP, the Serializer DefinitionCache could
63 infinite loop when the directory exists but is not listable. (#49)
64 - Don't match for <body> inside comments with
65 %Core.ConvertDocumentToFragment. (#67)
66 - SafeObject is now less case sensitive. (#57)
67 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
68 web form. (#85)
70 4.7.0, released 2015-08-04
71 # opacity is now considered a "tricky" CSS property rather than a
72 proprietary one.
73 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
74 an element should be considered "empty" (maybe preserve if it
75 has attributes), and modify iframe support so that the iframe
76 is removed if it is missing a src attribute. Thanks meeva for
77 reporting.
78 - Don't truncate upon encountering </div> when using DOMLex. Thanks
79 Myrto Christina for finally convincing me to fix this.
80 - Update YouTube filter for new code.
81 - Fix parsing of rgb() values with spaces in them for 'border'
82 attribute.
83 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
84 valME for reporting.
86 4.6.0, released 2013-11-30
87 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
88 Please update any verification scripts you may have.
89 # URI parsing algorithm was made more strict, so only prefixes which
90 looks like schemes will actually be schemes. Thanks
91 Michael Gusev <mgusev@sugarcrm.com> for fixing.
92 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
93 anything.
94 ! New directive %Core.AllowHostnameUnderscore which allows underscores
95 in hostnames.
96 - Eliminate quadratic behavior in DOMLex by using a proper queue.
97 Thanks Ole Laursen for noticing this.
98 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
99 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
100 Networks for sponsoring this work.
101 - Made Linkify URL parser a bit less permissive, so that non-breaking
102 spaces and commas are not included as part of URL. Thanks nAS for fixing.
103 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
104 David Hirtz for reporting.
105 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
106 for reporting.
108 4.5.0, released 2013-02-17
109 # Fix bug where stacked attribute transforms clobber each other;
110 this also means it's no longer possible to override attribute
111 transforms in later modules. No internal code was using this
112 but this may break some clients.
113 # We now use SHA-1 to identify cached definitions, instead of MD5.
114 ! Support display:inline-block
115 ! Support for more white-space CSS values.
116 ! Permit underscores in font families
117 ! Support for page-break-* CSS3 properties when proprietary properties
118 are enabled.
119 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
120 SGML excludes checking. If HTML Purifier is removing too much text
121 and you don't care about full standards compliance, try setting this to
122 'true'.
123 - Use prepend for SPL autoloading on PHP 5.3 and later.
124 - Fix bug with nofollow transform when pre-existing rel exists.
125 - Fix bug where background:url() always gets lower-cased
126 (but not background-image:url())
127 - Fix bug with non lower-case color names in HTML
128 - Fix bug where data URI validation doesn't remove temporary files.
129 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
130 - Don't remove certain empty tags on RemoveEmpty.
132 4.4.0, released 2012-01-18
133 # Removed PEARSax3 handler.
134 # URI.Munge now munges URIs inside the same host that go from https
135 to http. Reported by Neike Taika-Tessaro.
136 # Core.EscapeNonASCIICharacters now always transforms entities to
137 entities, even if target encoding is UTF-8.
138 # Tighten up selector validation in ExtractStyleBlocks.
139 Non-syntactically valid selectors are now rejected, along with
140 some of the more obscure ones such as attribute selectors, the
141 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
142 ID and class selectors now work properly with the relevant
143 configuration attributes. Also, mute errors when parsing CSS
144 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
145 ! Added support for 'scope' attribute on tables.
146 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
147 ! Properly handle sub-lists directly nested inside of lists in
148 a standards compliant way, by moving them into the preceding <li>
149 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
150 limited allowed comments in untrusted situations.
151 ! Implement iframes, and allow them to be used in untrusted mode with
152 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
153 <brad.froehle@gmail.com> for submitting an initial version of the patch.
154 ! The Forms module now works properly for transitional doctypes.
155 ! Added support for internationalized domain names. You need the PEAR
156 Net_IDNA2 module to be in your path; if it is installed, ensure the
157 class can be loaded and then set %Core.EnableIDNA to true.
158 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
159 <yramirez-htmlpurifier@adicio.com> for reporting.
160 - Explicitly initialize anonModule variable to null.
161 - Do not duplicate nofollow if already present. Thanks 178
162 for reporting.
163 - Do not add nofollow if hostname matches our current host. Thanks 178
164 for reporting, and Neike Taika-Tessaro for helping diagnose.
165 - Do not unset parser variable; this fixes intermittent serialization
166 problems. Thanks Neike Taika-Tessaro for reporting, bill
167 <10010tiger@gmail.com> for diagnosing.
168 - Fix iconv truncation bug, where non-UTF-8 target encodings see
169 output truncated after around 8000 characters. Thanks Jörg Ludwig
170 <joerg.ludwig@iserv.eu> for reporting.
171 - Fix broken table content model for XHTML1.1 (and also earlier
172 versions, although the W3C validator doesn't catch those violations).
173 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
175 4.3.0, released 2011-03-27
176 # Fixed broken caching of customized raw definitions, but requires an
177 API change. The old API still works but will emit a warning,
178 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
179 for how to upgrade your code.
180 # Protect against Internet Explorer innerHTML behavior by specially
181 treating attributes with backticks but no angled brackets, quotes or
182 spaces. This constitutes a slight semantic change, which can be
183 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
184 and Mario Heiderich.
185 # Protect against cssText/innerHTML by restricting allowed characters
186 used in fonts further than mandated by the specification and encoding
187 some extra special characters in URLs. Reported by Neike
188 Taika-Tessaro and Mario Heiderich.
189 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
190 ! More types of SPL autoloaders allowed on later versions of PHP.
191 ! Implementations for position, top, left, right, bottom, z-index
192 when %CSS.Trusted is on.
193 ! Add %Cache.SerializerPermissions option for custom serializer
194 directory/file permissions
195 ! Fix longstanding bug in Flash support for non-IE browsers, and
196 allow more wmode attributes.
197 ! Add %CSS.AllowedFonts to restrict permissible font names.
198 - Switch to an iterative traversal of the DOM, which prevents us
199 from running out of stack space for deeply nested documents.
200 Thanks Maxim Krizhanovsky for contributing a patch.
201 - Make removal of conditional IE comments ungreedy; thanks Bernd
202 for reporting.
203 - Escape CDATA before removing Internet Explorer comments.
204 - Fix removal of id attributes under certain conditions by ensuring
205 armor attributes are preserved when recreating tags.
206 - Check if schema.ser was corrupted.
207 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
208 This safety check is only done for HTMLPurifier.auto.php; if you
209 are using standalone or the specialized includes files, you're
210 expected to know what you're doing.
211 - Stop repeatedly writing the cache file after I'm done customizing a
212 raw definition. Reported by ajh.
213 - Switch to using require_once in the Bootstrap to work around bad
214 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
215 - Fix URI handling when hostname is missing but scheme is present.
216 Reported by Neike Taika-Tessaro.
217 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
218 for reporting.
219 - Fix harmless notice from indexing into empty string. Thanks Matthijs
220 Kooijman <matthijs@stdin.nl> for reporting.
221 - Don't autoclose no parent elements are able to support the element
222 that triggered the autoclose. In particular fixes strange behavior
223 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
224 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
226 4.2.0, released 2010-09-15
227 ! Added %Core.RemoveProcessingInstructions, which lets you remove
228 <? ... ?> statements.
229 ! Added %URI.DisableResources functionality; the directive originally
230 did nothing. Thanks David Rothstein for reporting.
231 ! Add documentation about configuration directive types.
232 ! Add %CSS.ForbiddenProperties configuration directive.
233 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
234 to utilize full-screen mode.
235 ! Add optional support for the <code>file</code> URI scheme, enable
236 by explicitly setting %URI.AllowedSchemes.
237 ! Add %Core.NormalizeNewlines options to allow turning off newline
238 normalization.
239 - Fix improper handling of Internet Explorer conditional comments
240 by parser. Thanks zmonteca for reporting.
241 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
242 Thanks sidepodcast for the fix.
243 - Warn if an element is allowed, but an attribute it requires is
244 not allowed.
246 4.1.1, released 2010-05-31
247 - Fix undefined index warnings in maintenance scripts.
248 - Fix bug in DirectLex for parsing elements with a single attribute
249 with entities.
250 - Rewrite CSS output logic for font-family and url(). Thanks Mario
251 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
252 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
253 - Emit an error for CollectErrors if a body is extracted
254 - Fix bug where in background-position for center keyword handling.
255 - Fix infinite loop when a wrapper element is inserted in a context
256 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
257 - Remove +x bit and shebang from index.php; only supported mode is to
258 explicitly call it with php.
259 - Make test script less chatty when log_errors is on.
261 4.1.0, released 2010-04-26
262 ! Support proprietary height attribute on table element
263 ! Support YouTube slideshows that contain /cp/ in their URL.
264 ! Support for data: URI scheme; not enabled by default, add it using
265 %URI.AllowedSchemes
266 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
267 ! Support for Internet Explorer compatibility with %HTML.SafeObject
268 using %Output.FlashCompat.
269 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
270 - Always quote the insides of url(...) in CSS.
272 4.0.0, released 2009-07-07
273 # APIs for ConfigSchema subsystem have substantially changed. See
274 docs/dev-config-bcbreaks.txt for details; in essence, anything that
275 had both namespace and directive now have a single unified key.
276 # Some configuration directives were renamed, specifically:
277 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
278 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
279 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
280 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
281 As usual, the old directive names will still work, but will throw E_NOTICE
282 errors.
283 # The allowed values for class have been relaxed to allow all of CDATA for
284 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
285 %Attr.ClassUseCDATA to false.
286 # Instead of appending the content model to an old content model, a blank
287 element will replace the old content model. You can use #SUPER to get
288 the old content model.
289 ! More robust support for name="" and id=""
290 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
291 configuration, and have changes to that configuration be propagated
292 to all of its children.
293 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
294 the name attribute when set. Use with care. Thanks Ian Cook for
295 sponsoring.
296 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
297 tags that contain non-breaking spaces as well other whitespace. You
298 can also modify which tags should have maintained with
299 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
300 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
301 classes users can use to a specified finite set of classes, and
302 %Attr.ForbiddenClasses, which is the logical inverse.
303 ! You can now maintain your own configuration schema directories by
304 creating a config-schema.php file or passing an extra argument. Check
305 docs/dev-config-schema.html for more details.
306 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
307 your configuration in a compact serial file, which you can unserialize
308 and use directly without having to go through the overhead of setup.
309 - Fix bug where URIDefinition would not get cleared if it's directives got
310 changed.
311 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
312 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
313 - Make %URI.Munge not apply to links that have the same host as your host.
314 - Prevent stray </body> tag from truncating output, if a second </body>
315 is present.
316 . Created script maintenance/rename-config.php for renaming a configuration
317 directive while maintaining its alias. This script does not change source code.
318 . Implement namespace locking for definition construction, to prevent
319 bugs where a directive is used for definition construction but is not
320 used to construct the cache hash.
322 3.3.0, released 2009-02-16
323 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
324 ! Implement generic property list classess
325 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
326 does not do the "right thing" with characters not supported in the output
327 set.
328 - Spellcheck UTF-8: The Secret To Character Encoding
329 - Fix improper removal of the contents of elements with only whitespace. Thanks
330 Eric Wald for reporting.
331 - Fix broken test suite in versions of PHP without spl_autoload_register()
332 - Fix degenerate case with YouTube filter involving double hyphens.
333 Thanks Pierre Attar for reporting.
334 - Fix YouTube rendering problem on certain versions of Firefox.
335 - Fix CSSDefinition Printer problems with decorators
336 - Add text parameter to unit tests, forces text output
337 . Add verbose mode to command line test runner, use (--verbose)
338 . Turn on unit tests for UnitConverter
339 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
340 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
341 tested on Linux.
342 . Removed trailing whitespace from all text files, see
343 remote-trailing-whitespace.php maintenance script.
344 . Convert configuration to use property list backend.
346 3.2.0, released 2008-10-31
347 # Using %Core.CollectErrors forces line number/column tracking on, whereas
348 previously you could theoretically turn it off.
349 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
350 use handleEnd() instead.
351 ! %Output.AttrSort for when you need your attributes in alphabetical order to
352 deal with a bug in FCKEditor. Requested by frank farmer.
353 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
354 ! Proper support for name attribute. It is now allowed and equivalent to the id
355 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
356 is heavy (for all doctypes).
357 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
358 use on hand-written HTML.
359 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
360 the strategy to be used, standalone, on untrusted input.
361 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
362 processing of left angled brackets in smileys and other whatnot.
363 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
364 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
365 the --only-phpt parameter, although for backwards-compatibility the flag
366 will still work.
367 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
368 Users who are not performing inbound filtering, this may seem a little
369 useless, but as a bonus, the test suite and handling of edge cases is also
370 improved.
371 ! Experimental implementation of forms for %HTML.Trusted
372 ! Track column numbers when maintain line numbers is on
373 ! Proprietary 'background' attribute on table-related elements converted into
374 corresponding CSS. Thanks Fusemail for sponsoring this feature!
375 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
376 supertype.
377 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
378 time of operation varies slightly from notifyEnd() as *all* end tokens are
379 processed by the injector before they are subject to the well-formedness rules.
380 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
381 basename of image when not present.
382 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
383 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
384 the other involving an undefined $is_folder error.
385 - Throw error when %Core.Encoding is set to a spurious value. Previously,
386 this errored silently and returned false.
387 - Redirected stderr to stdout for flush error output.
388 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
389 available.
390 - Do not re-munge URL if the output URL has the same host as the input URL.
391 Requested by Chris.
392 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
393 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
394 - Fix bug with inline elements in blockquotes conflicting with strict doctype
395 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
396 - Fix bug where dots and double-dots in absolute URLs without hostname were
397 not collapsed by URIFilter_MakeAbsolute.
398 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
399 by reordering their addition.
400 - Will now throw exception on many error conditions during lexer creation; also
401 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
402 is being used.
403 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
404 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
405 Reported by David Morton.
406 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
407 for more interesting filter-backtracking
408 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
409 index to reprocess tokens.
410 . StringHashParser now allows for multiline sections with "empty" content;
411 previously the section would remain undefined.
412 . Added --quick option to multitest.php, which tests only the most recent
413 release for each series.
414 . Added --distro option to multitest.php, which accepts either 'normal' or
415 'standalone'. This supercedes --exclude-normal and --exclude-standalone
417 3.1.1, released 2008-06-19
418 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
419 In order to enable this again, please set %URI.MungeResources to true.
420 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
421 and height/width HTML with %HTML.MaxImgLength.
422 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
423 for sponsoring this feature. Check out the corresponding documentation
424 for details. (Att Nightly testers: The API for this feature changed before
425 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
426 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
427 ! Implemented post URI filtering. Set member variable $post to true to set
428 a URIFilter as such.
429 ! Allow modules to define injectors via $info_injector. Injectors are
430 automatically disabled if injector's needed elements are not found.
431 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
432 Thanks Chris for sponsoring. If you've been using ad hoc code from the
433 forums, PLEASE use this instead.
434 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
435 embedded, tag name, attribute name, CSS property name). See %URI.Munge
436 for more details. Requested by Jochem Blok.
437 - Disable percent height/width attributes for img.
438 - AttrValidator operations are now atomic; updates to attributes are not
439 manifest in token until end of operations. This prevents naughty internal
440 code from directly modifying CurrentToken when they're not supposed to.
441 This semantics change was requested by frank farmer.
442 - Percent encoding checks enabled for URI query and fragment
443 - Fix stray backslashes in font-family; CSS Unicode character escapes are
444 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
445 for reporting.
446 - Improve parseCDATA algorithm to take into account newline normalization
447 - Account for browser confusion between Yen character and backslash in
448 Shift_JIS encoding. This fix generalizes to any other encoding which is not
449 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
450 - Fix missing configuration parameter in Generator calls. Thanks vs for the
451 partial patch.
452 - Improved adherence to Unicode by checking for non-character codepoints.
453 Thanks Geoffrey Sneddon for reporting. This may result in degraded
454 performance for extremely large inputs.
455 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
456 for reporting.
457 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
458 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
459 this class.
460 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
461 to __construct($min, $max). __construct(true) is equivalent to
462 __construct('0').
463 . Added HTMLPurifier_AttrDef_Switch class
464 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
465 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
466 get this called with the configuration object. All modules now
467 use this rather than __construct(), although legacy code using constructors
468 will still work--the new format, however, lets modules access the
469 configuration object for HTML namespace dependant tweaks.
470 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
471 . ConfigSchema data-structure heavily optimized; on average it uses a third
472 the memory it did previously. The interface has changed accordingly,
473 consult changes to HTMLPurifier_Config for details.
474 . Variable parsing types now are magic integers instead of strings
475 . Added benchmark for ConfigSchema
476 . HTMLPurifier_Generator requires $config and $context parameters. If you
477 don't know what they should be, use HTMLPurifier_Config::createDefault()
478 and new HTMLPurifier_Context().
479 . Printers now properly distinguish between output configuration, and
480 target configuration. This is not applicable to scripts using
481 the Printers for HTML Purifier related tasks.
482 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
483 fatal errors will ensue.
484 . URIFilter->prepare can return false in order to abort loading of the filter
485 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
486 an external resource.
487 . %URI.Munge functionality factored out into a post-filter class.
488 . Added CurrentCSSProperty context variable during CSS validation
490 3.1.0, released 2008-05-18
491 # Unnecessary references to objects (vestiges of PHP4) removed from method
492 signatures. The following methods do not need references when assigning from
493 them and will result in E_STRICT errors if you try:
494 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
495 + HTMLPurifier_ConfigSchema::instance()
496 + HTMLPurifier_DefinitionCacheFactory::instance()
497 + HTMLPurifier_DefinitionCacheFactory->create()
498 + HTMLPurifier_DoctypeRegistry->register()
499 + HTMLPurifier_DoctypeRegistry->get()
500 + HTMLPurifier_HTMLModule->addElement()
501 + HTMLPurifier_HTMLModule->addBlankElement()
502 + HTMLPurifier_LanguageFactory::instance()
503 # Printer_ConfigForm's get*() functions were static-ified
504 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
505 form of tag@attr, NOT tag.attr (which will throw an error and won't do
506 anything). This is for forwards compatibility with XML; you'd do best
507 to migrate an %HTML.AllowedAttributes directives to this syntax too.
508 ! Allow index to be false for config from form creation
509 ! Added HTMLPurifier::VERSION constant
510 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
511 and allows for version numbers like "3.1.0-dev".
512 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
513 ! HTML Purifier's URI handling is a lot more robust, with much stricter
514 validation checks and better percent encoding handling. Thanks Gareth Heyes
515 for indicating security vulnerabilities from lax percent encoding.
516 ! Bootstrap autoloader deals more robustly with classes that don't exist,
517 preventing class_exists($class, true) from barfing.
518 - InterchangeBuilder now alphabetizes its lists
519 - Validation error in configdoc output fixed
520 - Iconv and other encoding errors muted even with custom error handlers that
521 do not honor error_reporting
522 - Add protection against imagecrash attack with CSS height/width
523 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
524 - Fixed and revamped broken ConfigForm smoketest
525 - Bug with bool/null fields in Printer_ConfigForm fixed
526 - Bug with global forbidden attributes fixed
527 - Improved error messages for allowed and forbidden HTML elements and attributes
528 - Missing (or null) in configdoc documentation restored
529 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
530 of DOM), HTML Purifier punts to DirectLex
531 - Fatal error with unserialization of ScriptRequired
532 - Created directories are now chmod'ed properly
533 - Fixed bug with fallback languages in LanguageFactory
534 - Standalone testing setup properly with autoload
535 . Out-of-date documentation revised
536 . UTF-8 encoding check optimization as suggested by Diego
537 . HTMLPurifier_Error removed in favor of exceptions
538 . More copy() function removed; should use clone instead
539 . More extensive unit tests for HTMLDefinition
540 . assertPurification moved to central harness
541 . HTMLPurifier_Generator accepts $config and $context parameters during
542 instantiation, not runtime
543 . Double-quotes outside of attribute values are now unescaped
545 3.1.0rc1, released 2008-04-22
546 # Autoload support added. Internal require_once's removed in favor of an
547 explicit require list or autoloading. To use HTML Purifier,
548 you must now either use HTMLPurifier.auto.php
549 or HTMLPurifier.includes.php; setting the include path and including
550 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
551 as well to register our autoload handler (or modify your autoload function
552 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
553 HTMLPurifier.safe-includes.php for a less performance friendly but more
554 user-friendly library load.
555 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
556 information is stored in the ConfigSchema directory, and the
557 maintenance/generate-schema-cache.php generates the schema.ser file, which
558 is now instantiated. Support for userland schema changes coming soon!
559 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
560 alias; to get rid of these errors just modify your configuration to use
561 the new directive name.
562 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
563 enabled using %Filter.$filter_name or by setting your own filters using
564 %Filter.Custom
565 # Directive-level safety properties superceded in favor of module-level
566 safety. Internal method HTMLModule->addElement() has changed, although
567 the externally visible HTMLDefinition->addElement has *not* changed.
568 ! Extra utility classes for testing and non-library operations can
569 be found in extras/. Specifically, these are FSTools and ConfigDoc.
570 You may find a use for these in your own project, but right now they
571 are highly experimental and volatile.
572 ! Integration with PHPT allows for automated smoketests
573 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
574 by Chris. You can enable them with %HTML.Proprietary if your client
575 demands them.
576 ! Support for !important CSS cascade modifier. By default, this will be stripped
577 from CSS, but you can enable it using %CSS.AllowImportant
578 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
579 to true to use them.
580 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
581 Developer error (not enduser error) can cause these to be triggered.
582 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
583 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
584 mucking around with HTMLPurifier_CSSDefinition
585 ! ConfigDoc output has been enhanced with version and deprecation info.
586 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
587 - Autoclose now operates iteratively, i.e. <span><span><div> now has
588 both span tags closed.
589 - Various HTMLPurifier_Config convenience functions now accept another parameter
590 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
591 global default.
592 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
593 - Fix bug in ExtractStyleBlocks with comments in style tags
594 - Fix bug in comment parsing for DirectLex
595 - Flush output now displayed when in command line mode for unit tester
596 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
597 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
598 on the same element without emitting errors.
599 - Fixed fatal error in PH5P lexer with invalid tag names
600 . Plugins now get their own changelogs according to project conventions.
601 . Convert tokens to use instanceof, reducing memory footprint and
602 improving comparison speed.
603 . Dry runs now supported in SimpleTest; testing facilities improved
604 . Bootstrap class added for handling autoloading functionality
605 . Implemented recursive glob at FSTools->globr
606 . ConfigSchema now has instance methods for all corresponding define*
607 static methods.
608 . A couple of new historical maintenance scripts were added.
609 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
610 . tests/index.php can now be run from any directory.
611 . HTMLPurifier_Token subclasses split into seperate files
612 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
613 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
614 . New --php=php flag added, allows PHP executable to be specified (command
615 line only!)
616 . htmlpurifier_add_test() preferred method to translate test files in to
617 classes, because it handles PHPT files too.
618 . Debugger class is deprecated and will be removed soon.
619 . Command line argument parsing for testing scripts revamped, now --opt value
620 format is supported.
621 . Smoketests now cleanup after magic quotes
622 . Generator now can output comments (however, comments are still stripped
623 from HTML Purifier output)
624 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
625 HTMLPurifier_VarParser->parse()
626 . Integers auto-cast into float type by VarParser.
627 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
628 during cache generation
629 . Reordered script calls in maintenance/flush.php
630 . Command line scripts now honor exit codes
631 . When --flush fails in unit testers, abort tests and print message
632 . Improved documentation in docs/dev-flush.html about the maintenance scripts
633 . copy() methods removed in favor of clone keyword
635 3.0.0, released 2008-01-06
636 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
637 until PHP 4 is completely deprecated, but no new features will be added
638 to it.
639 + Visibility declarations added
640 + Constructor methods renamed to __construct()
641 + PHP4 reference cruft removed (in progress)
642 ! CSS properties are now case-insensitive
643 ! DefinitionCacheFactory now can register new implementations
644 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
645 documents and cleaning their contents up. Requires the CSSTidy library
646 <http://csstidy.sourceforge.net/>. You can access the blocks with the
647 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
648 The output CSS can also be "scoped" for a specific element, use:
649 %Filter.ExtractStyleBlocksScope
650 ! Experimental support for some proprietary CSS attributes allowed:
651 opacity (and all of the browser-specific equivalents) and scrollbar colors.
652 Enable by setting %CSS.Proprietary to true.
653 - Colors missing # but in hex form will be corrected
654 - CSS Number algorithm improved
655 - Unit testing and multi-testing now on steroids: command lines,
656 XML output, and other goodies now added.

658 . New classes:
659 + HTMLPurifier_AttrDef_CSS_AlphaValue
660 + HTMLPurifier_AttrDef_CSS_Filter
661 . Multitest now has a file docblock
663 2.1.3, released 2007-11-05
664 ! tests/multitest.php allows you to test multiple versions by running
665 tests/index.php through multiple interpreters using `phpv` shell
666 script (you must provide this script!)
667 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
668 on some systems.
669 - Injector algorithm further refined: off-by-one error regarding skip
670 counts for dormant injectors fixed
671 - Corrective blockquote definition now enabled for HTML 4.01 Strict
672 - Fatal error when <img> tag (or any other element with required attributes)
673 has 'id' attribute fixed, thanks NykO18 for reporting
674 - Fix warning emitted when a non-supported URI scheme is passed to the
675 MakeAbsolute URIFilter, thanks NykO18 (again)
676 - Further refine AutoParagraph injector. Behavior inside of elements
677 allowing paragraph tags clarified: only inline content delimeted by
678 double newlines (not block elements) are paragraphed.
679 - Buggy treatment of end tags of elements that have required attributes
680 fixed (does not manifest on default tag-set)
681 - Spurious internal content reorganization error suppressed
682 - HTMLDefinition->addElement now returns a reference to the created
683 element object, as implied by the documentation
684 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
685 - Fix a theoretical class of infinite loops from DirectLex reported
686 by Nate Abele
687 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
688 in PHP 5.1
689 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
690 HTMLDefinition errors, this may indicate problems with error-collecting
691 facilities in PHP 5
692 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
693 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
694 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
695 to better communicate its purpose
696 . Error unit tests can now specify the expectation of no errors. Future
697 iterations of the harness will be extremely strict about what errors
698 are allowed
699 . Extend Injector hooks to allow for more powerful injector routines
700 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
701 method
702 . Doxygen configuration file updated, with minor improvements
703 . Test runner now checks for similarly named files in conf/ directory too.
704 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
705 outputted
706 . Maintenance script for generating PH5P patch added, original PH5P source
707 file also added under version control
708 . Full unit test runner script title made more descriptive with PHP version
709 . Updated INSTALL file to state that 4.3.7 is the earliest version we
710 are actively testing
712 2.1.2, released 2007-09-03
713 ! Implemented Object module for trusted users
714 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
715 this to your code:
716 require_once 'HTMLPurifier/Lexer/PH5P.php';
717 $config->set('Core', 'LexerImpl', 'PH5P');
718 Note that this Lexer introduces some classes not in the HTMLPurifier
719 namespace. Also, this is PHP5 only.
720 ! CSS property border-spacing implemented
721 - Fix non-visible parsing error in DirectLex with empty tags that have
722 slashes inside attribute values.
723 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
724 accepted as valid CSS. Usually non-visible, because this styling is the
725 default for tables in most browsers. Thanks Brett Zamir for pointing
726 this out.
727 - Fix validation errors in configuration form
728 - Hammer out a bunch of edge-case bugs in the standalone distribution
729 - Inclusion reflection removed from URISchemeRegistry; you must manually
730 include any new schema files you wish to use
731 - Numerous typo fixes in documentation thanks to Brett Zamir
732 . Unit test refactoring for one logical test per test function
733 . Config and context parameters in ComplexHarness deprecated: instead, edit
734 the $config and $context member variables
735 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
736 really make a difference, but is good for completeness sake
737 . merge-library.php script refactored for greater code reusability and
738 PHP4 compatibility
740 2.1.1, released 2007-08-04
741 - Fix show-stopper bug in %URI.MakeAbsolute functionality
742 - Fix PHP4 syntax error in standalone version
743 . Add prefix directory to include path for standalone, this prevents
744 other installations from clobbering the standalone's URI schemes
745 . Single test methods can be invoked by prefixing with __only
747 2.1.0, released 2007-08-02
748 # flush-htmldefinition-cache.php superseded in favor of a generic
749 flush-definition-cache.php script, you can clear a specific cache
750 by passing its name as a parameter to the script
751 ! Phorum mod implemented for HTML Purifier
752 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
753 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
754 for PHP4 (DirectLex).
755 ! Standalone file now available, which greatly reduces the amount of
756 includes (although there are still a few files that reside in the
757 standalone folder)
758 ! Relative URIs can now be transformed into their absolute equivalents
759 using %URI.Base and %URI.MakeAbsolute
760 ! Ruby implemented for XHTML 1.1

765 need are not allowed
766 - ConfigForm's compactification of directive names is now configurable
767 - AutoParagraph autoformatter algorithm refined after field-testing
768 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
769 blockquote wrapping
770 - Contents of <style> tags removed by default when tags are removed
771 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
772 for output cache invalidation
773 . ConfigForm printer now can retrieve CSS and JS files as strings, in
774 case HTML Purifier's directory is not publically accessible
775 . Introduce new text/itext configuration directive values: these represent
776 longer strings that would be more appropriately edited with a textarea
777 . Allow newlines to act as separators for lists, hashes, lookups and
778 %HTML.Allowed
779 . ConfigForm generates textareas instead of text inputs for lists, hashes,
780 lookups, text and itext fields
781 . Hidden element content removal genericized: %Core.HiddenElements can
782 be used to customize this behavior, by default <script> and <style> are
783 hidden
784 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
785 . Custom ChildDef added to default include list
786 . URIScheme reflection improved: will not attempt to include file if class
787 already exists. May clobber autoload, so I need to keep an eye on it
788 . ConfigSchema heavily optimized, will only collect information and validate
789 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
790 . AttrDef_URI unit tests and implementation refactored
791 . benchmarks/ directory now protected from public view with .htaccess file;
792 run the tests via command line
793 . URI scheme is munged off if there is no authority and the scheme is the
794 default one
795 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
796 . Interface for URIScheme changed
797 . Generic URI object to hold components of URI added, most systems involved
798 in URI validation have been migrated to use it
799 . Custom filtering for URIs factored out to URIDefinition interface for
800 maximum extensibility
802 2.0.1, released 2007-06-27
803 ! Tag auto-closing now based on a ChildDef heuristic rather than a
804 manually set auto_close array; some behavior may change
805 ! Experimental AutoFormat functionality added: auto-paragraph and
806 linkify your HTML input by setting %AutoFormat.AutoParagraph and
807 %AutoFormat.Linkify to true
808 ! Newlines normalized internally, and then converted back to the
809 value of PHP_EOL. If this is not desired, set your newline format
810 using %Output.Newline.
811 ! Beta error collection, messages are implemented for the most generic
812 cases involving Lexing or Strategies
813 - Clean up special case code for <script> tags
814 - Reorder includes for DefinitionCache decorators, fixes a possible
815 missing class error
816 - Fixed bug where manually modified definitions were not saved via cache
817 (mostly harmless, except for the fact that it would be a little slower)
818 - Configuration objects with different serials do not clobber each
819 others when revision numbers are unequal
820 - Improve Serializer DefinitionCache directory permissions checks
821 - DefinitionCache no longer throws errors when it encounters old
822 serial files that do not conform to the current style
823 - Stray xmlns attributes removed from configuration documentation
824 - configForm.php smoketest no longer has XSS vulnerability due to
825 unescaped print_r output
826 - Printer adheres to configuration's directives on output format
827 - Fix improperly named form field in ConfigForm printer
828 . Rewire some test-cases to swallow errors rather than expect them
829 . HTMLDefinition printer updated with some of the new attributes
830 . DefinitionCache keys reordered to reflect precedence: version number,
831 hash, then revision number
832 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
833 . Interlinking in configuration documentation added using
834 Injector_PurifierLinkify
835 . Directives now keep track of aliases to themselves
836 . Error collector now requires a severity to be passed, use PHP's internal
837 error constants for this
838 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
839 much easier selective embedding of configuration values
840 . Doctype objects now accept public and system DTD identifiers
841 . %HTML.Doctype is now constrained by specific values, to specify a custom
842 doctype use new %HTML.CustomDoctype
843 . ConfigForm truncates long directives to keep the form small, and does
844 not re-output namespaces
846 2.0.0, released 2007-06-20
847 # Completely refactored HTMLModuleManager, decentralizing safety
848 information
849 # Transform modules changed to Tidy modules, which offer more flexibility
850 and better modularization
851 # Configuration object now finalizes itself when a read operation is
852 performed on it, ensuring that its internal state stays consistent.
853 To revert this behavior, you can set the $autoFinalize member variable
854 off, but it's not recommended.
855 # New compact syntax for AttrDef objects that can be used to instantiate
856 new objects via make()
857 # Definitions (esp. HTMLDefinition) are now cached for a significant
858 performance boost. You can disable caching by setting %Core.DefinitionCache
859 to null. You CANNOT edit raw definitions without setting the corresponding
860 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
861 # Contents between <script> tags are now completely removed if <script>
862 is not allowed
863 # Prototype-declarations for Lexer removed in favor of configuration
864 determination of Lexer implementations.
865 ! HTML Purifier now works in PHP 4.3.2.

869 format: key1:value1,key2:value2
870 ! ConfigDoc now factored into OOP design
871 ! All deprecated elements now natively supported
872 ! Implement TinyMCE styled whitelist specification format in
873 %HTML.Allowed
874 ! Config object gives more friendly error messages when things go wrong
875 ! Advanced API implemented: easy functions for creating elements (addElement)
876 and attributes (addAttribute) on HTMLDefinition
877 ! Add native support for required attributes
878 - Deprecated and removed EnableRedundantUTF8Cleaning. It didn't even work!
879 - DOMLex will not emit errors when a custom error handler that does not
880 honor error_reporting is used
881 - StrictBlockquote child definition refrains from wrapping whitespace
882 in tags now.
883 - Bug resulting from tag transforms to non-allowed elements fixed
884 - ChildDef_Custom's regex generation has been improved, removing several
885 false positives
886 . Unit test for ElementDef created, ElementDef behavior modified to
887 be more flexible
888 . Added convenience functions for HTMLModule constructors
889 . AttrTypes now has accessor functions that should be used instead
890 of directly manipulating info
891 . TagTransform_Center deprecated in favor of generic TagTransform_Simple
892 . Add extra protection in AttrDef_URI against phantom Schemes
893 . Doctype object added to HTMLDefinition which describes certain aspects
894 of the operational document type
895 . Lexer is now pre-emptively included, with a conditional include for the
896 PHP5 only version.
897 . HTMLDefinition and CSSDefinition have a common parent class: Definition.
898 . DirectLex can now track line-numbers
899 . Preliminary error collector is in place, although no code actually reports
900 errors yet
901 . Factor out most of ValidateAttributes to new AttrValidator class
903 1.6.1, released 2007-05-05
904 ! Support for more deprecated attributes via transformations:
905 + hspace and vspace in img
906 + size and noshade in hr
907 + nowrap in td
908 + clear in br
909 + align in caption, table, img and hr
910 + type in ul, ol and li
911 ! DirectLex now preserves text in which a < bracket is followed by
912 a non-alphanumeric character. This means that certain emoticons
913 are now preserved.
914 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
915 images will hang around with an empty src
916 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
917 to enable
918 ! CSS property white-space now allows nowrap (supported in all modern
919 browsers) but not others (which have spotty browser implementations)
920 ! XHTML 1.1 mode now sort-of works without any fatal errors, and
921 lang is now moved over to xml:lang.

955 1.5.0, released 2007-03-23
956 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
957 doesn't actually do anything yet, but keep your eyes peeled.

971 and HTMLDefinition->content_sets

980 . Modify Youtube filter regexp to be multiline
981 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
