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 - Fix PREG_BACKTRACK_LIMIT_ERROR in HTMLPurifier_Filter_ExtractStyle.
34 Thanks @breathbath for contributing the report and fix (#120)
35 - Fix entity decoding algorithm to be more conservative about
36 decoding entities that are missing trailing semicolon.
37 To get old behavior, set %Core.LegacyEntityDecoder to true.
38 (#119)
39 - Workaround libxml bug when HTML tags are embedded inside
40 script tags. To disable workaround set %Core.AggressivelyRemoveScript
41 to false. (#83)
42 # By default, when a link has a target attribute associated
43 with it, we now also add rel="noopener" in order to
44 prevent the new window from being able to overwrite
45 the original frame. To disable this protection,
46 set %HTML.TargetNoopener to FALSE.
48 4.8.0, released 2016-07-16
49 # By default, when a link has a target attribute associated
50 with it, we now also add rel="noreferrer" in order to
51 prevent the new window from being able to overwrite
52 the original frame. To disable this protection,
53 set %HTML.TargetNoreferrer to FALSE.
54 ! Full PHP 7 compatibility, the test suite is ALL GO.
55 ! %CSS.AllowDuplicates permits duplicate CSS properties.
56 ! Support for 'tel' URIs.
57 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
58 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
59 yet supported.
60 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
61 - alt truncation could result in malformed UTF-8 sequence. Don't
62 truncate. Thanks Brandon Farber for reporting.
63 - Linkify regex is smarter, based off of Gruber's regex.
64 - IDNA supported natively on PHP 5.3 and later.
65 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
66 allowed.
67 - Minor bounds error fix to squash a PHP 7 notice.
68 - Support non-/tmp temporary directories for data:// validation
69 - Give a better error message when a user attempts to allow
70 ul/ol without allowing li.
71 - On some versions of PHP, the Serializer DefinitionCache could
72 infinite loop when the directory exists but is not listable. (#49)
73 - Don't match for <body> inside comments with
74 %Core.ConvertDocumentToFragment. (#67)
75 - SafeObject is now less case sensitive. (#57)
76 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
77 web form. (#85)
79 4.7.0, released 2015-08-04
80 # opacity is now considered a "tricky" CSS property rather than a
81 proprietary one.
82 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
83 an element should be considered "empty" (maybe preserve if it
84 has attributes), and modify iframe support so that the iframe
85 is removed if it is missing a src attribute. Thanks meeva for
86 reporting.
87 - Don't truncate upon encountering </div> when using DOMLex. Thanks
88 Myrto Christina for finally convincing me to fix this.
89 - Update YouTube filter for new code.
90 - Fix parsing of rgb() values with spaces in them for 'border'
91 attribute.
92 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
93 valME for reporting.
95 4.6.0, released 2013-11-30
96 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
97 Please update any verification scripts you may have.
98 # URI parsing algorithm was made more strict, so only prefixes which
99 looks like schemes will actually be schemes. Thanks
100 Michael Gusev <mgusev@sugarcrm.com> for fixing.
101 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
102 anything.
103 ! New directive %Core.AllowHostnameUnderscore which allows underscores
104 in hostnames.
105 - Eliminate quadratic behavior in DOMLex by using a proper queue.
106 Thanks Ole Laursen for noticing this.
107 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
108 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
109 Networks for sponsoring this work.
110 - Made Linkify URL parser a bit less permissive, so that non-breaking
111 spaces and commas are not included as part of URL. Thanks nAS for fixing.
112 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
113 David Hirtz for reporting.
114 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
115 for reporting.
117 4.5.0, released 2013-02-17
118 # Fix bug where stacked attribute transforms clobber each other;
119 this also means it's no longer possible to override attribute
120 transforms in later modules. No internal code was using this
121 but this may break some clients.
122 # We now use SHA-1 to identify cached definitions, instead of MD5.
123 ! Support display:inline-block
124 ! Support for more white-space CSS values.
125 ! Permit underscores in font families
126 ! Support for page-break-* CSS3 properties when proprietary properties
127 are enabled.
128 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
129 SGML excludes checking. If HTML Purifier is removing too much text
130 and you don't care about full standards compliance, try setting this to
131 'true'.
132 - Use prepend for SPL autoloading on PHP 5.3 and later.
133 - Fix bug with nofollow transform when pre-existing rel exists.
134 - Fix bug where background:url() always gets lower-cased
135 (but not background-image:url())
136 - Fix bug with non lower-case color names in HTML
137 - Fix bug where data URI validation doesn't remove temporary files.
138 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
139 - Don't remove certain empty tags on RemoveEmpty.
141 4.4.0, released 2012-01-18
142 # Removed PEARSax3 handler.
143 # URI.Munge now munges URIs inside the same host that go from https
144 to http. Reported by Neike Taika-Tessaro.
145 # Core.EscapeNonASCIICharacters now always transforms entities to
146 entities, even if target encoding is UTF-8.
147 # Tighten up selector validation in ExtractStyleBlocks.
148 Non-syntactically valid selectors are now rejected, along with
149 some of the more obscure ones such as attribute selectors, the
150 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
151 ID and class selectors now work properly with the relevant
152 configuration attributes. Also, mute errors when parsing CSS
153 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
154 ! Added support for 'scope' attribute on tables.
155 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
156 ! Properly handle sub-lists directly nested inside of lists in
157 a standards compliant way, by moving them into the preceding <li>
158 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
159 limited allowed comments in untrusted situations.
160 ! Implement iframes, and allow them to be used in untrusted mode with
161 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
162 <brad.froehle@gmail.com> for submitting an initial version of the patch.
163 ! The Forms module now works properly for transitional doctypes.
164 ! Added support for internationalized domain names. You need the PEAR
165 Net_IDNA2 module to be in your path; if it is installed, ensure the
166 class can be loaded and then set %Core.EnableIDNA to true.
167 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
168 <yramirez-htmlpurifier@adicio.com> for reporting.
169 - Explicitly initialize anonModule variable to null.
170 - Do not duplicate nofollow if already present. Thanks 178
171 for reporting.
172 - Do not add nofollow if hostname matches our current host. Thanks 178
173 for reporting, and Neike Taika-Tessaro for helping diagnose.
174 - Do not unset parser variable; this fixes intermittent serialization
175 problems. Thanks Neike Taika-Tessaro for reporting, bill
176 <10010tiger@gmail.com> for diagnosing.
177 - Fix iconv truncation bug, where non-UTF-8 target encodings see
178 output truncated after around 8000 characters. Thanks Jörg Ludwig
179 <joerg.ludwig@iserv.eu> for reporting.
180 - Fix broken table content model for XHTML1.1 (and also earlier
181 versions, although the W3C validator doesn't catch those violations).
182 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
184 4.3.0, released 2011-03-27
185 # Fixed broken caching of customized raw definitions, but requires an
186 API change. The old API still works but will emit a warning,
187 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
188 for how to upgrade your code.
189 # Protect against Internet Explorer innerHTML behavior by specially
190 treating attributes with backticks but no angled brackets, quotes or
191 spaces. This constitutes a slight semantic change, which can be
192 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
193 and Mario Heiderich.
194 # Protect against cssText/innerHTML by restricting allowed characters
195 used in fonts further than mandated by the specification and encoding
196 some extra special characters in URLs. Reported by Neike
197 Taika-Tessaro and Mario Heiderich.
198 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
199 ! More types of SPL autoloaders allowed on later versions of PHP.
200 ! Implementations for position, top, left, right, bottom, z-index
201 when %CSS.Trusted is on.
202 ! Add %Cache.SerializerPermissions option for custom serializer
203 directory/file permissions
204 ! Fix longstanding bug in Flash support for non-IE browsers, and
205 allow more wmode attributes.
206 ! Add %CSS.AllowedFonts to restrict permissible font names.
207 - Switch to an iterative traversal of the DOM, which prevents us
208 from running out of stack space for deeply nested documents.
209 Thanks Maxim Krizhanovsky for contributing a patch.
210 - Make removal of conditional IE comments ungreedy; thanks Bernd
211 for reporting.
212 - Escape CDATA before removing Internet Explorer comments.
213 - Fix removal of id attributes under certain conditions by ensuring
214 armor attributes are preserved when recreating tags.
215 - Check if schema.ser was corrupted.
216 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
217 This safety check is only done for HTMLPurifier.auto.php; if you
218 are using standalone or the specialized includes files, you're
219 expected to know what you're doing.
220 - Stop repeatedly writing the cache file after I'm done customizing a
221 raw definition. Reported by ajh.
222 - Switch to using require_once in the Bootstrap to work around bad
223 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
224 - Fix URI handling when hostname is missing but scheme is present.
225 Reported by Neike Taika-Tessaro.
226 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
227 for reporting.
228 - Fix harmless notice from indexing into empty string. Thanks Matthijs
229 Kooijman <matthijs@stdin.nl> for reporting.
230 - Don't autoclose no parent elements are able to support the element
231 that triggered the autoclose. In particular fixes strange behavior
232 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
233 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
235 4.2.0, released 2010-09-15
236 ! Added %Core.RemoveProcessingInstructions, which lets you remove
237 <? ... ?> statements.
238 ! Added %URI.DisableResources functionality; the directive originally
239 did nothing. Thanks David Rothstein for reporting.
240 ! Add documentation about configuration directive types.
241 ! Add %CSS.ForbiddenProperties configuration directive.
242 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
243 to utilize full-screen mode.
244 ! Add optional support for the <code>file</code> URI scheme, enable
245 by explicitly setting %URI.AllowedSchemes.
246 ! Add %Core.NormalizeNewlines options to allow turning off newline
247 normalization.
248 - Fix improper handling of Internet Explorer conditional comments
249 by parser. Thanks zmonteca for reporting.
250 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
251 Thanks sidepodcast for the fix.
252 - Warn if an element is allowed, but an attribute it requires is
253 not allowed.
255 4.1.1, released 2010-05-31
256 - Fix undefined index warnings in maintenance scripts.
257 - Fix bug in DirectLex for parsing elements with a single attribute
258 with entities.
259 - Rewrite CSS output logic for font-family and url(). Thanks Mario
260 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
261 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
262 - Emit an error for CollectErrors if a body is extracted
263 - Fix bug where in background-position for center keyword handling.
264 - Fix infinite loop when a wrapper element is inserted in a context
265 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
266 - Remove +x bit and shebang from index.php; only supported mode is to
267 explicitly call it with php.
268 - Make test script less chatty when log_errors is on.
270 4.1.0, released 2010-04-26
271 ! Support proprietary height attribute on table element
272 ! Support YouTube slideshows that contain /cp/ in their URL.
273 ! Support for data: URI scheme; not enabled by default, add it using
274 %URI.AllowedSchemes
275 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
276 ! Support for Internet Explorer compatibility with %HTML.SafeObject
277 using %Output.FlashCompat.
278 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
279 - Always quote the insides of url(...) in CSS.
281 4.0.0, released 2009-07-07
282 # APIs for ConfigSchema subsystem have substantially changed. See
283 docs/dev-config-bcbreaks.txt for details; in essence, anything that
284 had both namespace and directive now have a single unified key.
285 # Some configuration directives were renamed, specifically:
286 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
287 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
288 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
289 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
290 As usual, the old directive names will still work, but will throw E_NOTICE
291 errors.
292 # The allowed values for class have been relaxed to allow all of CDATA for
293 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
294 %Attr.ClassUseCDATA to false.
295 # Instead of appending the content model to an old content model, a blank
296 element will replace the old content model. You can use #SUPER to get
297 the old content model.
298 ! More robust support for name="" and id=""
299 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
300 configuration, and have changes to that configuration be propagated
301 to all of its children.
302 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
303 the name attribute when set. Use with care. Thanks Ian Cook for
304 sponsoring.
305 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
306 tags that contain non-breaking spaces as well other whitespace. You
307 can also modify which tags should have maintained with
308 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
309 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
310 classes users can use to a specified finite set of classes, and
311 %Attr.ForbiddenClasses, which is the logical inverse.
312 ! You can now maintain your own configuration schema directories by
313 creating a config-schema.php file or passing an extra argument. Check
314 docs/dev-config-schema.html for more details.
315 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
316 your configuration in a compact serial file, which you can unserialize
317 and use directly without having to go through the overhead of setup.
318 - Fix bug where URIDefinition would not get cleared if it's directives got
319 changed.
320 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
321 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
322 - Make %URI.Munge not apply to links that have the same host as your host.
323 - Prevent stray </body> tag from truncating output, if a second </body>
324 is present.
325 . Created script maintenance/rename-config.php for renaming a configuration
326 directive while maintaining its alias. This script does not change source code.
327 . Implement namespace locking for definition construction, to prevent
328 bugs where a directive is used for definition construction but is not
329 used to construct the cache hash.
331 3.3.0, released 2009-02-16
332 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
333 ! Implement generic property list classess
334 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
335 does not do the "right thing" with characters not supported in the output
336 set.
337 - Spellcheck UTF-8: The Secret To Character Encoding
338 - Fix improper removal of the contents of elements with only whitespace. Thanks
339 Eric Wald for reporting.
340 - Fix broken test suite in versions of PHP without spl_autoload_register()
341 - Fix degenerate case with YouTube filter involving double hyphens.
342 Thanks Pierre Attar for reporting.
343 - Fix YouTube rendering problem on certain versions of Firefox.
344 - Fix CSSDefinition Printer problems with decorators
345 - Add text parameter to unit tests, forces text output
346 . Add verbose mode to command line test runner, use (--verbose)
347 . Turn on unit tests for UnitConverter
348 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
349 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
350 tested on Linux.
351 . Removed trailing whitespace from all text files, see
352 remote-trailing-whitespace.php maintenance script.
353 . Convert configuration to use property list backend.
355 3.2.0, released 2008-10-31
356 # Using %Core.CollectErrors forces line number/column tracking on, whereas
357 previously you could theoretically turn it off.
358 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
359 use handleEnd() instead.
360 ! %Output.AttrSort for when you need your attributes in alphabetical order to
361 deal with a bug in FCKEditor. Requested by frank farmer.
362 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
363 ! Proper support for name attribute. It is now allowed and equivalent to the id
364 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
365 is heavy (for all doctypes).
366 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
367 use on hand-written HTML.
368 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
369 the strategy to be used, standalone, on untrusted input.
370 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
371 processing of left angled brackets in smileys and other whatnot.
372 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
373 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
374 the --only-phpt parameter, although for backwards-compatibility the flag
375 will still work.
376 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
377 Users who are not performing inbound filtering, this may seem a little
378 useless, but as a bonus, the test suite and handling of edge cases is also
379 improved.
380 ! Experimental implementation of forms for %HTML.Trusted
381 ! Track column numbers when maintain line numbers is on
382 ! Proprietary 'background' attribute on table-related elements converted into
383 corresponding CSS. Thanks Fusemail for sponsoring this feature!
384 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
385 supertype.
386 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
387 time of operation varies slightly from notifyEnd() as *all* end tokens are
388 processed by the injector before they are subject to the well-formedness rules.
389 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
390 basename of image when not present.
391 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
392 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
393 the other involving an undefined $is_folder error.
394 - Throw error when %Core.Encoding is set to a spurious value. Previously,
395 this errored silently and returned false.
396 - Redirected stderr to stdout for flush error output.
397 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
398 available.
399 - Do not re-munge URL if the output URL has the same host as the input URL.
400 Requested by Chris.
401 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
402 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
403 - Fix bug with inline elements in blockquotes conflicting with strict doctype
404 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
405 - Fix bug where dots and double-dots in absolute URLs without hostname were
406 not collapsed by URIFilter_MakeAbsolute.
407 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
408 by reordering their addition.
409 - Will now throw exception on many error conditions during lexer creation; also
410 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
411 is being used.
412 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
413 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
414 Reported by David Morton.
415 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
416 for more interesting filter-backtracking
417 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
418 index to reprocess tokens.
419 . StringHashParser now allows for multiline sections with "empty" content;
420 previously the section would remain undefined.
421 . Added --quick option to multitest.php, which tests only the most recent
422 release for each series.
423 . Added --distro option to multitest.php, which accepts either 'normal' or
424 'standalone'. This supercedes --exclude-normal and --exclude-standalone
426 3.1.1, released 2008-06-19
427 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
428 In order to enable this again, please set %URI.MungeResources to true.
429 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
430 and height/width HTML with %HTML.MaxImgLength.
431 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
432 for sponsoring this feature. Check out the corresponding documentation
433 for details. (Att Nightly testers: The API for this feature changed before
434 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
435 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
436 ! Implemented post URI filtering. Set member variable $post to true to set
437 a URIFilter as such.
438 ! Allow modules to define injectors via $info_injector. Injectors are
439 automatically disabled if injector's needed elements are not found.
440 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
441 Thanks Chris for sponsoring. If you've been using ad hoc code from the
442 forums, PLEASE use this instead.
443 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
444 embedded, tag name, attribute name, CSS property name). See %URI.Munge
445 for more details. Requested by Jochem Blok.
446 - Disable percent height/width attributes for img.
447 - AttrValidator operations are now atomic; updates to attributes are not
448 manifest in token until end of operations. This prevents naughty internal
449 code from directly modifying CurrentToken when they're not supposed to.
450 This semantics change was requested by frank farmer.
451 - Percent encoding checks enabled for URI query and fragment
452 - Fix stray backslashes in font-family; CSS Unicode character escapes are
453 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
454 for reporting.
455 - Improve parseCDATA algorithm to take into account newline normalization
456 - Account for browser confusion between Yen character and backslash in
457 Shift_JIS encoding. This fix generalizes to any other encoding which is not
458 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
459 - Fix missing configuration parameter in Generator calls. Thanks vs for the
460 partial patch.
461 - Improved adherence to Unicode by checking for non-character codepoints.
462 Thanks Geoffrey Sneddon for reporting. This may result in degraded
463 performance for extremely large inputs.
464 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
465 for reporting.
466 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
467 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
468 this class.
469 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
470 to __construct($min, $max). __construct(true) is equivalent to
471 __construct('0').
472 . Added HTMLPurifier_AttrDef_Switch class
473 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
474 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
475 get this called with the configuration object. All modules now
476 use this rather than __construct(), although legacy code using constructors
477 will still work--the new format, however, lets modules access the
478 configuration object for HTML namespace dependant tweaks.
479 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
480 . ConfigSchema data-structure heavily optimized; on average it uses a third
481 the memory it did previously. The interface has changed accordingly,
482 consult changes to HTMLPurifier_Config for details.
483 . Variable parsing types now are magic integers instead of strings
484 . Added benchmark for ConfigSchema
485 . HTMLPurifier_Generator requires $config and $context parameters. If you
486 don't know what they should be, use HTMLPurifier_Config::createDefault()
487 and new HTMLPurifier_Context().
488 . Printers now properly distinguish between output configuration, and
489 target configuration. This is not applicable to scripts using
490 the Printers for HTML Purifier related tasks.
491 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
492 fatal errors will ensue.
493 . URIFilter->prepare can return false in order to abort loading of the filter
494 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
495 an external resource.
496 . %URI.Munge functionality factored out into a post-filter class.
497 . Added CurrentCSSProperty context variable during CSS validation
499 3.1.0, released 2008-05-18
500 # Unnecessary references to objects (vestiges of PHP4) removed from method
501 signatures. The following methods do not need references when assigning from
502 them and will result in E_STRICT errors if you try:
503 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
504 + HTMLPurifier_ConfigSchema::instance()
505 + HTMLPurifier_DefinitionCacheFactory::instance()
506 + HTMLPurifier_DefinitionCacheFactory->create()
507 + HTMLPurifier_DoctypeRegistry->register()
508 + HTMLPurifier_DoctypeRegistry->get()
509 + HTMLPurifier_HTMLModule->addElement()
510 + HTMLPurifier_HTMLModule->addBlankElement()
511 + HTMLPurifier_LanguageFactory::instance()
512 # Printer_ConfigForm's get*() functions were static-ified
513 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
514 form of tag@attr, NOT tag.attr (which will throw an error and won't do
515 anything). This is for forwards compatibility with XML; you'd do best
516 to migrate an %HTML.AllowedAttributes directives to this syntax too.
517 ! Allow index to be false for config from form creation
518 ! Added HTMLPurifier::VERSION constant
519 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
520 and allows for version numbers like "3.1.0-dev".
521 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
522 ! HTML Purifier's URI handling is a lot more robust, with much stricter
523 validation checks and better percent encoding handling. Thanks Gareth Heyes
524 for indicating security vulnerabilities from lax percent encoding.
525 ! Bootstrap autoloader deals more robustly with classes that don't exist,
526 preventing class_exists($class, true) from barfing.
527 - InterchangeBuilder now alphabetizes its lists
528 - Validation error in configdoc output fixed
529 - Iconv and other encoding errors muted even with custom error handlers that
530 do not honor error_reporting
531 - Add protection against imagecrash attack with CSS height/width
532 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
533 - Fixed and revamped broken ConfigForm smoketest
534 - Bug with bool/null fields in Printer_ConfigForm fixed
535 - Bug with global forbidden attributes fixed
536 - Improved error messages for allowed and forbidden HTML elements and attributes
537 - Missing (or null) in configdoc documentation restored
538 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
539 of DOM), HTML Purifier punts to DirectLex
540 - Fatal error with unserialization of ScriptRequired
541 - Created directories are now chmod'ed properly
542 - Fixed bug with fallback languages in LanguageFactory
543 - Standalone testing setup properly with autoload
544 . Out-of-date documentation revised
545 . UTF-8 encoding check optimization as suggested by Diego
546 . HTMLPurifier_Error removed in favor of exceptions
547 . More copy() function removed; should use clone instead
548 . More extensive unit tests for HTMLDefinition
549 . assertPurification moved to central harness
550 . HTMLPurifier_Generator accepts $config and $context parameters during
551 instantiation, not runtime
552 . Double-quotes outside of attribute values are now unescaped
554 3.1.0rc1, released 2008-04-22
555 # Autoload support added. Internal require_once's removed in favor of an
556 explicit require list or autoloading. To use HTML Purifier,
557 you must now either use HTMLPurifier.auto.php
558 or HTMLPurifier.includes.php; setting the include path and including
559 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
560 as well to register our autoload handler (or modify your autoload function
561 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
562 HTMLPurifier.safe-includes.php for a less performance friendly but more
563 user-friendly library load.
564 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
565 information is stored in the ConfigSchema directory, and the
566 maintenance/generate-schema-cache.php generates the schema.ser file, which
567 is now instantiated. Support for userland schema changes coming soon!
568 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
569 alias; to get rid of these errors just modify your configuration to use
570 the new directive name.
571 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
572 enabled using %Filter.$filter_name or by setting your own filters using
573 %Filter.Custom
574 # Directive-level safety properties superceded in favor of module-level
575 safety. Internal method HTMLModule->addElement() has changed, although
576 the externally visible HTMLDefinition->addElement has *not* changed.
577 ! Extra utility classes for testing and non-library operations can
578 be found in extras/. Specifically, these are FSTools and ConfigDoc.
579 You may find a use for these in your own project, but right now they
580 are highly experimental and volatile.
581 ! Integration with PHPT allows for automated smoketests
582 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
583 by Chris. You can enable them with %HTML.Proprietary if your client
584 demands them.
585 ! Support for !important CSS cascade modifier. By default, this will be stripped
586 from CSS, but you can enable it using %CSS.AllowImportant
587 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
588 to true to use them.
589 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
590 Developer error (not enduser error) can cause these to be triggered.
591 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
592 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
593 mucking around with HTMLPurifier_CSSDefinition
594 ! ConfigDoc output has been enhanced with version and deprecation info.
595 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
596 - Autoclose now operates iteratively, i.e. <span><span><div> now has
597 both span tags closed.
598 - Various HTMLPurifier_Config convenience functions now accept another parameter
599 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
600 global default.
601 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
602 - Fix bug in ExtractStyleBlocks with comments in style tags
603 - Fix bug in comment parsing for DirectLex
604 - Flush output now displayed when in command line mode for unit tester
605 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
606 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
607 on the same element without emitting errors.
608 - Fixed fatal error in PH5P lexer with invalid tag names
609 . Plugins now get their own changelogs according to project conventions.
610 . Convert tokens to use instanceof, reducing memory footprint and
611 improving comparison speed.
612 . Dry runs now supported in SimpleTest; testing facilities improved
613 . Bootstrap class added for handling autoloading functionality
614 . Implemented recursive glob at FSTools->globr
615 . ConfigSchema now has instance methods for all corresponding define*
616 static methods.
617 . A couple of new historical maintenance scripts were added.
618 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
619 . tests/index.php can now be run from any directory.
620 . HTMLPurifier_Token subclasses split into seperate files
621 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
622 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
623 . New --php=php flag added, allows PHP executable to be specified (command
624 line only!)
625 . htmlpurifier_add_test() preferred method to translate test files in to
626 classes, because it handles PHPT files too.
627 . Debugger class is deprecated and will be removed soon.
628 . Command line argument parsing for testing scripts revamped, now --opt value
629 format is supported.
630 . Smoketests now cleanup after magic quotes
631 . Generator now can output comments (however, comments are still stripped
632 from HTML Purifier output)
633 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
634 HTMLPurifier_VarParser->parse()
635 . Integers auto-cast into float type by VarParser.
636 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
637 during cache generation
638 . Reordered script calls in maintenance/flush.php
639 . Command line scripts now honor exit codes
640 . When --flush fails in unit testers, abort tests and print message
641 . Improved documentation in docs/dev-flush.html about the maintenance scripts
642 . copy() methods removed in favor of clone keyword
644 3.0.0, released 2008-01-06
645 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
646 until PHP 4 is completely deprecated, but no new features will be added
647 to it.
648 + Visibility declarations added
649 + Constructor methods renamed to __construct()
650 + PHP4 reference cruft removed (in progress)
651 ! CSS properties are now case-insensitive
652 ! DefinitionCacheFactory now can register new implementations
653 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
654 documents and cleaning their contents up. Requires the CSSTidy library
655 <http://csstidy.sourceforge.net/>. You can access the blocks with the
656 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
657 The output CSS can also be "scoped" for a specific element, use:
658 %Filter.ExtractStyleBlocksScope
659 ! Experimental support for some proprietary CSS attributes allowed:
660 opacity (and all of the browser-specific equivalents) and scrollbar colors.
661 Enable by setting %CSS.Proprietary to true.
662 - Colors missing # but in hex form will be corrected
663 - CSS Number algorithm improved
664 - Unit testing and multi-testing now on steroids: command lines,
665 XML output, and other goodies now added.

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

773 - AutoFormatters emit friendly error messages if tags or attributes they
774 need are not allowed
775 - ConfigForm's compactification of directive names is now configurable
776 - AutoParagraph autoformatter algorithm refined after field-testing
777 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
778 blockquote wrapping
779 - Contents of <style> tags removed by default when tags are removed
780 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
781 for output cache invalidation
782 . ConfigForm printer now can retrieve CSS and JS files as strings, in
783 case HTML Purifier's directory is not publically accessible
784 . Introduce new text/itext configuration directive values: these represent
785 longer strings that would be more appropriately edited with a textarea
786 . Allow newlines to act as separators for lists, hashes, lookups and
787 %HTML.Allowed
788 . ConfigForm generates textareas instead of text inputs for lists, hashes,
789 lookups, text and itext fields
790 . Hidden element content removal genericized: %Core.HiddenElements can
791 be used to customize this behavior, by default <script> and <style> are
792 hidden
793 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
794 . Custom ChildDef added to default include list
795 . URIScheme reflection improved: will not attempt to include file if class
796 already exists. May clobber autoload, so I need to keep an eye on it
797 . ConfigSchema heavily optimized, will only collect information and validate
798 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
799 . AttrDef_URI unit tests and implementation refactored
800 . benchmarks/ directory now protected from public view with .htaccess file;
801 run the tests via command line
802 . URI scheme is munged off if there is no authority and the scheme is the
803 default one
804 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
805 . Interface for URIScheme changed
806 . Generic URI object to hold components of URI added, most systems involved
807 in URI validation have been migrated to use it
808 . Custom filtering for URIs factored out to URIDefinition interface for
809 maximum extensibility
811 2.0.1, released 2007-06-27
812 ! Tag auto-closing now based on a ChildDef heuristic rather than a
813 manually set auto_close array; some behavior may change
814 ! Experimental AutoFormat functionality added: auto-paragraph and
815 linkify your HTML input by setting %AutoFormat.AutoParagraph and
816 %AutoFormat.Linkify to true
817 ! Newlines normalized internally, and then converted back to the
818 value of PHP_EOL. If this is not desired, set your newline format
819 using %Output.Newline.
820 ! Beta error collection, messages are implemented for the most generic
821 cases involving Lexing or Strategies
822 - Clean up special case code for <script> tags
823 - Reorder includes for DefinitionCache decorators, fixes a possible
824 missing class error
825 - Fixed bug where manually modified definitions were not saved via cache
826 (mostly harmless, except for the fact that it would be a little slower)
827 - Configuration objects with different serials do not clobber each
828 others when revision numbers are unequal
829 - Improve Serializer DefinitionCache directory permissions checks
830 - DefinitionCache no longer throws errors when it encounters old
831 serial files that do not conform to the current style
832 - Stray xmlns attributes removed from configuration documentation
833 - configForm.php smoketest no longer has XSS vulnerability due to
834 unescaped print_r output
835 - Printer adheres to configuration's directives on output format
836 - Fix improperly named form field in ConfigForm printer
837 . Rewire some test-cases to swallow errors rather than expect them
838 . HTMLDefinition printer updated with some of the new attributes
839 . DefinitionCache keys reordered to reflect precedence: version number,
840 hash, then revision number
841 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
842 . Interlinking in configuration documentation added using
843 Injector_PurifierLinkify
844 . Directives now keep track of aliases to themselves
845 . Error collector now requires a severity to be passed, use PHP's internal
846 error constants for this
847 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
848 much easier selective embedding of configuration values
849 . Doctype objects now accept public and system DTD identifiers
850 . %HTML.Doctype is now constrained by specific values, to specify a custom
851 doctype use new %HTML.CustomDoctype
852 . ConfigForm truncates long directives to keep the form small, and does
853 not re-output namespaces
855 2.0.0, released 2007-06-20
856 # Completely refactored HTMLModuleManager, decentralizing safety
857 information
858 # Transform modules changed to Tidy modules, which offer more flexibility
859 and better modularization
860 # Configuration object now finalizes itself when a read operation is
861 performed on it, ensuring that its internal state stays consistent.
862 To revert this behavior, you can set the $autoFinalize member variable
863 off, but it's not recommended.
864 # New compact syntax for AttrDef objects that can be used to instantiate
865 new objects via make()
866 # Definitions (esp. HTMLDefinition) are now cached for a significant
867 performance boost. You can disable caching by setting %Core.DefinitionCache
868 to null. You CANNOT edit raw definitions without setting the corresponding
869 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
870 # Contents between <script> tags are now completely removed if <script>
871 is not allowed
872 # Prototype-declarations for Lexer removed in favor of configuration
873 determination of Lexer implementations.
874 ! HTML Purifier now works in PHP 4.3.2.
875 ! Configuration form-editing API makes tweaking HTMLPurifier_Config a
876 breeze!
877 ! Configuration directives that accept hashes now allow new string
878 format: key1:value1,key2:value2
879 ! ConfigDoc now factored into OOP design
880 ! All deprecated elements now natively supported
881 ! Implement TinyMCE styled whitelist specification format in
882 %HTML.Allowed
883 ! Config object gives more friendly error messages when things go wrong
884 ! Advanced API implemented: easy functions for creating elements (addElement)
885 and attributes (addAttribute) on HTMLDefinition
886 ! Add native support for required attributes
887 - Deprecated and removed EnableRedundantUTF8Cleaning. It didn't even work!
888 - DOMLex will not emit errors when a custom error handler that does not
889 honor error_reporting is used
890 - StrictBlockquote child definition refrains from wrapping whitespace
891 in tags now.
892 - Bug resulting from tag transforms to non-allowed elements fixed
893 - ChildDef_Custom's regex generation has been improved, removing several
894 false positives
895 . Unit test for ElementDef created, ElementDef behavior modified to
896 be more flexible
897 . Added convenience functions for HTMLModule constructors
898 . AttrTypes now has accessor functions that should be used instead
899 of directly manipulating info
900 . TagTransform_Center deprecated in favor of generic TagTransform_Simple
901 . Add extra protection in AttrDef_URI against phantom Schemes
902 . Doctype object added to HTMLDefinition which describes certain aspects
903 of the operational document type
904 . Lexer is now pre-emptively included, with a conditional include for the
905 PHP5 only version.
906 . HTMLDefinition and CSSDefinition have a common parent class: Definition.
907 . DirectLex can now track line-numbers
908 . Preliminary error collector is in place, although no code actually reports
909 errors yet
910 . Factor out most of ValidateAttributes to new AttrValidator class
912 1.6.1, released 2007-05-05
913 ! Support for more deprecated attributes via transformations:
914 + hspace and vspace in img
915 + size and noshade in hr
916 + nowrap in td
917 + clear in br
918 + align in caption, table, img and hr
919 + type in ul, ol and li
920 ! DirectLex now preserves text in which a < bracket is followed by
921 a non-alphanumeric character. This means that certain emoticons
922 are now preserved.
923 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
924 images will hang around with an empty src
925 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
926 to enable

964 1.5.0, released 2007-03-23
965 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
966 doesn't actually do anything yet, but keep your eyes peeled.

980 and HTMLDefinition->content_sets
981 . StrictBlockquote now reports what elements its supposed to allow,

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