1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.8.0, unknown release date
13 # By default, when a link has a target attribute associated
14 with it, we now also add rel="noreferrer" in order to
15 prevent the new window from being able to overwrite
16 the original frame. To disable this protection,
17 set %HTML.TargetNoreferrer to FALSE.
18 ! Full PHP 7 compatibility, the test suite is ALL GO.
19 ! %CSS.AllowDuplicates permits duplicate CSS properties.
20 ! Support for 'tel' URIs.
21 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
22 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
24 - alt truncation could result in malformed UTF-8 sequence. Don't
25 truncate. Thanks Brandon Farber for reporting.
26 - Linkify regex is smarter, based off of Gruber's regex.
27 - IDNA supported natively on PHP 5.3 and later.
28 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
30 - Minor bounds error fix to squash a PHP 7 notice.
31 - Support non-/tmp temporary directories for data:// validation
32 - Give a better error message when a user attempts to allow
33 ul/ol without allowing li.
34 - On some versions of PHP, the Serializer DefinitionCache could
35 infinite loop when the directory exists but is not listable. (#49)
36 - Don't match for <body> inside comments with
37 %Core.ConvertDocumentToFragment. (#67)
38 - SafeObject is now less case sensitive. (#57)
39 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
42 4.7.0, released 2015-08-04
43 # opacity is now considered a "tricky" CSS property rather than a
45 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
46 an element should be considered "empty" (maybe preserve if it
47 has attributes), and modify iframe support so that the iframe
48 is removed if it is missing a src attribute. Thanks meeva for
50 - Don't truncate upon encountering </div> when using DOMLex. Thanks
51 Myrto Christina for finally convincing me to fix this.
52 - Update YouTube filter for new code.
53 - Fix parsing of rgb() values with spaces in them for 'border'
55 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
58 4.6.0, released 2013-11-30
59 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
60 Please update any verification scripts you may have.
61 # URI parsing algorithm was made more strict, so only prefixes which
62 looks like schemes will actually be schemes. Thanks
63 Michael Gusev <mgusev@sugarcrm.com> for fixing.
64 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
66 ! New directive %Core.AllowHostnameUnderscore which allows underscores
68 - Eliminate quadratic behavior in DOMLex by using a proper queue.
69 Thanks Ole Laursen for noticing this.
70 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
71 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
72 Networks for sponsoring this work.
73 - Made Linkify URL parser a bit less permissive, so that non-breaking
74 spaces and commas are not included as part of URL. Thanks nAS for fixing.
75 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
76 David Hirtz for reporting.
77 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
80 4.5.0, released 2013-02-17
81 # Fix bug where stacked attribute transforms clobber each other;
82 this also means it's no longer possible to override attribute
83 transforms in later modules. No internal code was using this
84 but this may break some clients.
85 # We now use SHA-1 to identify cached definitions, instead of MD5.
86 ! Support display:inline-block
87 ! Support for more white-space CSS values.
88 ! Permit underscores in font families
89 ! Support for page-break-* CSS3 properties when proprietary properties
91 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
92 SGML excludes checking. If HTML Purifier is removing too much text
93 and you don't care about full standards compliance, try setting this to
95 - Use prepend for SPL autoloading on PHP 5.3 and later.
96 - Fix bug with nofollow transform when pre-existing rel exists.
97 - Fix bug where background:url() always gets lower-cased
98 (but not background-image:url())
99 - Fix bug with non lower-case color names in HTML
100 - Fix bug where data URI validation doesn't remove temporary files.
101 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
102 - Don't remove certain empty tags on RemoveEmpty.
104 4.4.0, released 2012-01-18
105 # Removed PEARSax3 handler.
106 # URI.Munge now munges URIs inside the same host that go from https
107 to http. Reported by Neike Taika-Tessaro.
108 # Core.EscapeNonASCIICharacters now always transforms entities to
109 entities, even if target encoding is UTF-8.
110 # Tighten up selector validation in ExtractStyleBlocks.
111 Non-syntactically valid selectors are now rejected, along with
112 some of the more obscure ones such as attribute selectors, the
113 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
114 ID and class selectors now work properly with the relevant
115 configuration attributes. Also, mute errors when parsing CSS
116 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
117 ! Added support for 'scope' attribute on tables.
118 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
119 ! Properly handle sub-lists directly nested inside of lists in
120 a standards compliant way, by moving them into the preceding <li>
121 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
122 limited allowed comments in untrusted situations.
123 ! Implement iframes, and allow them to be used in untrusted mode with
124 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
125 <brad.froehle@gmail.com> for submitting an initial version of the patch.
126 ! The Forms module now works properly for transitional doctypes.
127 ! Added support for internationalized domain names. You need the PEAR
128 Net_IDNA2 module to be in your path; if it is installed, ensure the
129 class can be loaded and then set %Core.EnableIDNA to true.
130 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
131 <yramirez-htmlpurifier@adicio.com> for reporting.
132 - Explicitly initialize anonModule variable to null.
133 - Do not duplicate nofollow if already present. Thanks 178
135 - Do not add nofollow if hostname matches our current host. Thanks 178
136 for reporting, and Neike Taika-Tessaro for helping diagnose.
137 - Do not unset parser variable; this fixes intermittent serialization
138 problems. Thanks Neike Taika-Tessaro for reporting, bill
139 <10010tiger@gmail.com> for diagnosing.
140 - Fix iconv truncation bug, where non-UTF-8 target encodings see
141 output truncated after around 8000 characters. Thanks Jörg Ludwig
142 <joerg.ludwig@iserv.eu> for reporting.
143 - Fix broken table content model for XHTML1.1 (and also earlier
144 versions, although the W3C validator doesn't catch those violations).
145 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
147 4.3.0, released 2011-03-27
148 # Fixed broken caching of customized raw definitions, but requires an
149 API change. The old API still works but will emit a warning,
150 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
151 for how to upgrade your code.
152 # Protect against Internet Explorer innerHTML behavior by specially
153 treating attributes with backticks but no angled brackets, quotes or
154 spaces. This constitutes a slight semantic change, which can be
155 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
157 # Protect against cssText/innerHTML by restricting allowed characters
158 used in fonts further than mandated by the specification and encoding
159 some extra special characters in URLs. Reported by Neike
160 Taika-Tessaro and Mario Heiderich.
161 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
162 ! More types of SPL autoloaders allowed on later versions of PHP.
163 ! Implementations for position, top, left, right, bottom, z-index
164 when %CSS.Trusted is on.
165 ! Add %Cache.SerializerPermissions option for custom serializer
166 directory/file permissions
167 ! Fix longstanding bug in Flash support for non-IE browsers, and
168 allow more wmode attributes.
169 ! Add %CSS.AllowedFonts to restrict permissible font names.
170 - Switch to an iterative traversal of the DOM, which prevents us
171 from running out of stack space for deeply nested documents.
172 Thanks Maxim Krizhanovsky for contributing a patch.
173 - Make removal of conditional IE comments ungreedy; thanks Bernd
175 - Escape CDATA before removing Internet Explorer comments.
176 - Fix removal of id attributes under certain conditions by ensuring
177 armor attributes are preserved when recreating tags.
178 - Check if schema.ser was corrupted.
179 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
180 This safety check is only done for HTMLPurifier.auto.php; if you
181 are using standalone or the specialized includes files, you're
182 expected to know what you're doing.
183 - Stop repeatedly writing the cache file after I'm done customizing a
184 raw definition. Reported by ajh.
185 - Switch to using require_once in the Bootstrap to work around bad
186 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
187 - Fix URI handling when hostname is missing but scheme is present.
188 Reported by Neike Taika-Tessaro.
189 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
191 - Fix harmless notice from indexing into empty string. Thanks Matthijs
192 Kooijman <matthijs@stdin.nl> for reporting.
193 - Don't autoclose no parent elements are able to support the element
194 that triggered the autoclose. In particular fixes strange behavior
195 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
196 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
198 4.2.0, released 2010-09-15
199 ! Added %Core.RemoveProcessingInstructions, which lets you remove
200 <? ... ?> statements.
201 ! Added %URI.DisableResources functionality; the directive originally
202 did nothing. Thanks David Rothstein for reporting.
203 ! Add documentation about configuration directive types.
204 ! Add %CSS.ForbiddenProperties configuration directive.
205 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
206 to utilize full-screen mode.
207 ! Add optional support for the <code>file</code> URI scheme, enable
208 by explicitly setting %URI.AllowedSchemes.
209 ! Add %Core.NormalizeNewlines options to allow turning off newline
211 - Fix improper handling of Internet Explorer conditional comments
212 by parser. Thanks zmonteca for reporting.
213 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
214 Thanks sidepodcast for the fix.
215 - Warn if an element is allowed, but an attribute it requires is
218 4.1.1, released 2010-05-31
219 - Fix undefined index warnings in maintenance scripts.
220 - Fix bug in DirectLex for parsing elements with a single attribute
222 - Rewrite CSS output logic for font-family and url(). Thanks Mario
223 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
224 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
225 - Emit an error for CollectErrors if a body is extracted
226 - Fix bug where in background-position for center keyword handling.
227 - Fix infinite loop when a wrapper element is inserted in a context
228 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
229 - Remove +x bit and shebang from index.php; only supported mode is to
230 explicitly call it with php.
231 - Make test script less chatty when log_errors is on.
233 4.1.0, released 2010-04-26
234 ! Support proprietary height attribute on table element
235 ! Support YouTube slideshows that contain /cp/ in their URL.
236 ! Support for data: URI scheme; not enabled by default, add it using
238 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
239 ! Support for Internet Explorer compatibility with %HTML.SafeObject
240 using %Output.FlashCompat.
241 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
242 - Always quote the insides of url(...) in CSS.
244 4.0.0, released 2009-07-07
245 # APIs for ConfigSchema subsystem have substantially changed. See
246 docs/dev-config-bcbreaks.txt for details; in essence, anything that
247 had both namespace and directive now have a single unified key.
248 # Some configuration directives were renamed, specifically:
249 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
250 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
251 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
252 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
253 As usual, the old directive names will still work, but will throw E_NOTICE
255 # The allowed values for class have been relaxed to allow all of CDATA for
256 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
257 %Attr.ClassUseCDATA to false.
258 # Instead of appending the content model to an old content model, a blank
259 element will replace the old content model. You can use #SUPER to get
260 the old content model.
261 ! More robust support for name="" and id=""
262 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
263 configuration, and have changes to that configuration be propagated
264 to all of its children.
265 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
266 the name attribute when set. Use with care. Thanks Ian Cook for
268 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
269 tags that contain non-breaking spaces as well other whitespace. You
270 can also modify which tags should have maintained with
271 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
272 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
273 classes users can use to a specified finite set of classes, and
274 %Attr.ForbiddenClasses, which is the logical inverse.
275 ! You can now maintain your own configuration schema directories by
276 creating a config-schema.php file or passing an extra argument. Check
277 docs/dev-config-schema.html for more details.
278 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
279 your configuration in a compact serial file, which you can unserialize
280 and use directly without having to go through the overhead of setup.
281 - Fix bug where URIDefinition would not get cleared if it's directives got
283 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
284 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
285 - Make %URI.Munge not apply to links that have the same host as your host.
286 - Prevent stray </body> tag from truncating output, if a second </body>
288 . Created script maintenance/rename-config.php for renaming a configuration
289 directive while maintaining its alias. This script does not change source code.
290 . Implement namespace locking for definition construction, to prevent
291 bugs where a directive is used for definition construction but is not
292 used to construct the cache hash.
294 3.3.0, released 2009-02-16
295 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
296 ! Implement generic property list classess
297 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
298 does not do the "right thing" with characters not supported in the output
300 - Spellcheck UTF-8: The Secret To Character Encoding
301 - Fix improper removal of the contents of elements with only whitespace. Thanks
302 Eric Wald for reporting.
303 - Fix broken test suite in versions of PHP without spl_autoload_register()
304 - Fix degenerate case with YouTube filter involving double hyphens.
305 Thanks Pierre Attar for reporting.
306 - Fix YouTube rendering problem on certain versions of Firefox.
307 - Fix CSSDefinition Printer problems with decorators
308 - Add text parameter to unit tests, forces text output
309 . Add verbose mode to command line test runner, use (--verbose)
310 . Turn on unit tests for UnitConverter
311 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
312 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
314 . Removed trailing whitespace from all text files, see
315 remote-trailing-whitespace.php maintenance script.
316 . Convert configuration to use property list backend.
318 3.2.0, released 2008-10-31
319 # Using %Core.CollectErrors forces line number/column tracking on, whereas
320 previously you could theoretically turn it off.
321 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
322 use handleEnd() instead.
323 ! %Output.AttrSort for when you need your attributes in alphabetical order to
324 deal with a bug in FCKEditor. Requested by frank farmer.
325 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
326 ! Proper support for name attribute. It is now allowed and equivalent to the id
327 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
328 is heavy (for all doctypes).
329 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
330 use on hand-written HTML.
331 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
332 the strategy to be used, standalone, on untrusted input.
333 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
334 processing of left angled brackets in smileys and other whatnot.
335 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
336 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
337 the --only-phpt parameter, although for backwards-compatibility the flag
339 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
340 Users who are not performing inbound filtering, this may seem a little
341 useless, but as a bonus, the test suite and handling of edge cases is also
343 ! Experimental implementation of forms for %HTML.Trusted
344 ! Track column numbers when maintain line numbers is on
345 ! Proprietary 'background' attribute on table-related elements converted into
346 corresponding CSS. Thanks Fusemail for sponsoring this feature!
347 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
349 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
350 time of operation varies slightly from notifyEnd() as *all* end tokens are
351 processed by the injector before they are subject to the well-formedness rules.
352 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
353 basename of image when not present.
354 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
355 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
356 the other involving an undefined $is_folder error.
357 - Throw error when %Core.Encoding is set to a spurious value. Previously,
358 this errored silently and returned false.
359 - Redirected stderr to stdout for flush error output.
360 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
362 - Do not re-munge URL if the output URL has the same host as the input URL.
364 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
365 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
366 - Fix bug with inline elements in blockquotes conflicting with strict doctype
367 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
368 - Fix bug where dots and double-dots in absolute URLs without hostname were
369 not collapsed by URIFilter_MakeAbsolute.
370 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
371 by reordering their addition.
372 - Will now throw exception on many error conditions during lexer creation; also
373 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
375 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
376 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
377 Reported by David Morton.
378 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
379 for more interesting filter-backtracking
380 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
381 index to reprocess tokens.
382 . StringHashParser now allows for multiline sections with "empty" content;
383 previously the section would remain undefined.
384 . Added --quick option to multitest.php, which tests only the most recent
385 release for each series.
386 . Added --distro option to multitest.php, which accepts either 'normal' or
387 'standalone'. This supercedes --exclude-normal and --exclude-standalone
389 3.1.1, released 2008-06-19
390 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
391 In order to enable this again, please set %URI.MungeResources to true.
392 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
393 and height/width HTML with %HTML.MaxImgLength.
394 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
395 for sponsoring this feature. Check out the corresponding documentation
396 for details. (Att Nightly testers: The API for this feature changed before
397 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
398 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
399 ! Implemented post URI filtering. Set member variable $post to true to set
401 ! Allow modules to define injectors via $info_injector. Injectors are
402 automatically disabled if injector's needed elements are not found.
403 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
404 Thanks Chris for sponsoring. If you've been using ad hoc code from the
405 forums, PLEASE use this instead.
406 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
407 embedded, tag name, attribute name, CSS property name). See %URI.Munge
408 for more details. Requested by Jochem Blok.
409 - Disable percent height/width attributes for img.
410 - AttrValidator operations are now atomic; updates to attributes are not
411 manifest in token until end of operations. This prevents naughty internal
412 code from directly modifying CurrentToken when they're not supposed to.
413 This semantics change was requested by frank farmer.
414 - Percent encoding checks enabled for URI query and fragment
415 - Fix stray backslashes in font-family; CSS Unicode character escapes are
416 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
418 - Improve parseCDATA algorithm to take into account newline normalization
419 - Account for browser confusion between Yen character and backslash in
420 Shift_JIS encoding. This fix generalizes to any other encoding which is not
421 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
422 - Fix missing configuration parameter in Generator calls. Thanks vs for the
424 - Improved adherence to Unicode by checking for non-character codepoints.
425 Thanks Geoffrey Sneddon for reporting. This may result in degraded
426 performance for extremely large inputs.
427 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
429 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
430 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
432 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
433 to __construct($min, $max). __construct(true) is equivalent to
435 . Added HTMLPurifier_AttrDef_Switch class
436 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
437 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
438 get this called with the configuration object. All modules now
439 use this rather than __construct(), although legacy code using constructors
440 will still work--the new format, however, lets modules access the
441 configuration object for HTML namespace dependant tweaks.
442 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
443 . ConfigSchema data-structure heavily optimized; on average it uses a third
444 the memory it did previously. The interface has changed accordingly,
445 consult changes to HTMLPurifier_Config for details.
446 . Variable parsing types now are magic integers instead of strings
447 . Added benchmark for ConfigSchema
448 . HTMLPurifier_Generator requires $config and $context parameters. If you
449 don't know what they should be, use HTMLPurifier_Config::createDefault()
450 and new HTMLPurifier_Context().
451 . Printers now properly distinguish between output configuration, and
452 target configuration. This is not applicable to scripts using
453 the Printers for HTML Purifier related tasks.
454 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
455 fatal errors will ensue.
456 . URIFilter->prepare can return false in order to abort loading of the filter
457 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
458 an external resource.
459 . %URI.Munge functionality factored out into a post-filter class.
460 . Added CurrentCSSProperty context variable during CSS validation
462 3.1.0, released 2008-05-18
463 # Unnecessary references to objects (vestiges of PHP4) removed from method
464 signatures. The following methods do not need references when assigning from
465 them and will result in E_STRICT errors if you try:
466 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
467 + HTMLPurifier_ConfigSchema::instance()
468 + HTMLPurifier_DefinitionCacheFactory::instance()
469 + HTMLPurifier_DefinitionCacheFactory->create()
470 + HTMLPurifier_DoctypeRegistry->register()
471 + HTMLPurifier_DoctypeRegistry->get()
472 + HTMLPurifier_HTMLModule->addElement()
473 + HTMLPurifier_HTMLModule->addBlankElement()
474 + HTMLPurifier_LanguageFactory::instance()
475 # Printer_ConfigForm's get*() functions were static-ified
476 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
477 form of tag@attr, NOT tag.attr (which will throw an error and won't do
478 anything). This is for forwards compatibility with XML; you'd do best
479 to migrate an %HTML.AllowedAttributes directives to this syntax too.
480 ! Allow index to be false for config from form creation
481 ! Added HTMLPurifier::VERSION constant
482 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
483 and allows for version numbers like "3.1.0-dev".
484 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
485 ! HTML Purifier's URI handling is a lot more robust, with much stricter
486 validation checks and better percent encoding handling. Thanks Gareth Heyes
487 for indicating security vulnerabilities from lax percent encoding.
488 ! Bootstrap autoloader deals more robustly with classes that don't exist,
489 preventing class_exists($class, true) from barfing.

515 . Double-quotes outside of attribute values are now unescaped
517 3.1.0rc1, released 2008-04-22
518 # Autoload support added. Internal require_once's removed in favor of an
519 explicit require list or autoloading. To use HTML Purifier,
520 you must now either use HTMLPurifier.auto.php
521 or HTMLPurifier.includes.php; setting the include path and including
522 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
523 as well to register our autoload handler (or modify your autoload function
524 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
525 HTMLPurifier.safe-includes.php for a less performance friendly but more
526 user-friendly library load.
527 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
528 information is stored in the ConfigSchema directory, and the
529 maintenance/generate-schema-cache.php generates the schema.ser file, which
530 is now instantiated. Support for userland schema changes coming soon!
531 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
532 alias; to get rid of these errors just modify your configuration to use
533 the new directive name.
534 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
535 enabled using %Filter.$filter_name or by setting your own filters using
537 # Directive-level safety properties superceded in favor of module-level
538 safety. Internal method HTMLModule->addElement() has changed, although
539 the externally visible HTMLDefinition->addElement has *not* changed.
540 ! Extra utility classes for testing and non-library operations can
541 be found in extras/. Specifically, these are FSTools and ConfigDoc.
542 You may find a use for these in your own project, but right now they
543 are highly experimental and volatile.
544 ! Integration with PHPT allows for automated smoketests
545 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
546 by Chris. You can enable them with %HTML.Proprietary if your client
548 ! Support for !important CSS cascade modifier. By default, this will be stripped
549 from CSS, but you can enable it using %CSS.AllowImportant
550 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
552 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
553 Developer error (not enduser error) can cause these to be triggered.
554 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
555 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
556 mucking around with HTMLPurifier_CSSDefinition
557 ! ConfigDoc output has been enhanced with version and deprecation info.
558 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.

591 . Command line argument parsing for testing scripts revamped, now --opt value
593 . Smoketests now cleanup after magic quotes
594 . Generator now can output comments (however, comments are still stripped

621 %Filter.ExtractStyleBlocksScope
622 ! Experimental support for some proprietary CSS attributes allowed:
623 opacity (and all of the browser-specific equivalents) and scrollbar colors.
624 Enable by setting %CSS.Proprietary to true.

665 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
666 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
667 to better communicate its purpose
668 . Error unit tests can now specify the expectation of no errors. Future
669 iterations of the harness will be extremely strict about what errors

688 require_once 'HTMLPurifier/Lexer/PH5P.php';
689 $config->set('Core', 'LexerImpl', 'PH5P');
690 Note that this Lexer introduces some classes not in the HTMLPurifier
691 namespace. Also, this is PHP5 only.
692 ! CSS property border-spacing implemented
693 - Fix non-visible parsing error in DirectLex with empty tags that have
694 slashes inside attribute values.
695 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
696 accepted as valid CSS. Usually non-visible, because this styling is the
697 default for tables in most browsers. Thanks Brett Zamir for pointing
699 - Fix validation errors in configuration form
700 - Hammer out a bunch of edge-case bugs in the standalone distribution
701 - Inclusion reflection removed from URISchemeRegistry; you must manually
702 include any new schema files you wish to use
703 - Numerous typo fixes in documentation thanks to Brett Zamir
704 . Unit test refactoring for one logical test per test function
705 . Config and context parameters in ComplexHarness deprecated: instead, edit
706 the $config and $context member variables
707 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
708 really make a difference, but is good for completeness sake
709 . merge-library.php script refactored for greater code reusability and

723 ! Phorum mod implemented for HTML Purifier
724 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
725 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary

744 for output cache invalidation
745 . ConfigForm printer now can retrieve CSS and JS files as strings, in
746 case HTML Purifier's directory is not publically accessible
747 . Introduce new text/itext configuration directive values: these represent
748 longer strings that would be more appropriately edited with a textarea

751 . ConfigForm generates textareas instead of text inputs for lists, hashes,
752 lookups, text and itext fields

754 be used to customize this behavior, by default <script> and <style> are
756 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
757 . Custom ChildDef added to default include list
758 . URIScheme reflection improved: will not attempt to include file if class

776 manually set auto_close array; some behavior may change
777 ! Experimental AutoFormat functionality added: auto-paragraph and
778 linkify your HTML input by setting %AutoFormat.AutoParagraph and
779 %AutoFormat.Linkify to true
780 ! Newlines normalized internally, and then converted back to the
781 value of PHP_EOL. If this is not desired, set your newline format
782 using %Output.Newline.
783 ! Beta error collection, messages are implemented for the most generic
784 cases involving Lexing or Strategies
785 - Clean up special case code for <script> tags

811 much easier selective embedding of configuration values
812 . Doctype objects now accept public and system DTD identifiers
813 . %HTML.Doctype is now constrained by specific values, to specify a custom
814 doctype use new %HTML.CustomDoctype
815 . ConfigForm truncates long directives to keep the form small, and does
816 not re-output namespaces
818 2.0.0, released 2007-06-20
819 # Completely refactored HTMLModuleManager, decentralizing safety
821 # Transform modules changed to Tidy modules, which offer more flexibility
822 and better modularization
823 # Configuration object now finalizes itself when a read operation is
824 performed on it, ensuring that its internal state stays consistent.
825 To revert this behavior, you can set the $autoFinalize member variable
826 off, but it's not recommended.
827 # New compact syntax for AttrDef objects that can be used to instantiate
828 new objects via make()
829 # Definitions (esp. HTMLDefinition) are now cached for a significant
830 performance boost. You can disable caching by setting %Core.DefinitionCache
831 to null. You CANNOT edit raw definitions without setting the corresponding
832 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
833 # Contents between <script> tags are now completely removed if <script>
835 # Prototype-declarations for Lexer removed in favor of configuration
