10 ==========================
12 4.8.0, unknown release date
13 ! Full PHP 7 compatibility, the test suite is ALL GO.
14 ! %CSS.AllowDuplicates permits duplicate CSS properties.
15 - alt truncation could result in malformed UTF-8 sequence. Don't
16 truncate. Thanks Brandon Farber for reporting.
17 - Linkify regex is smarter, based off of Gruber's regex.
18 - IDNA supported natively on PHP 5.3 and later.
19 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
21 - Minor bounds error fix to squash a PHP 7 notice.
22 - Support non-/tmp temporary directories for data:// validation
23 - Give a better error message when a user attempts to allow
24 ul/ol without allowing li.
26 4.7.0, released 2015-08-04
27 # opacity is now considered a "tricky" CSS property rather than a
29 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
30 an element should be considered "empty" (maybe preserve if it
31 has attributes), and modify iframe support so that the iframe
32 is removed if it is missing a src attribute. Thanks meeva for
34 - Don't truncate upon encountering </div> when using DOMLex. Thanks
35 Myrto Christina for finally convincing me to fix this.
36 - Update YouTube filter for new code.
37 - Fix parsing of rgb() values with spaces in them for 'border'
39 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
42 4.6.0, released 2013-11-30
43 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
44 Please update any verification scripts you may have.
45 # URI parsing algorithm was made more strict, so only prefixes which
46 looks like schemes will actually be schemes. Thanks
47 Michael Gusev <mgusev@sugarcrm.com> for fixing.
48 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
50 ! New directive %Core.AllowHostnameUnderscore which allows underscores
52 - Eliminate quadratic behavior in DOMLex by using a proper queue.
53 Thanks Ole Laursen for noticing this.
54 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
55 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
56 Networks for sponsoring this work.
57 - Made Linkify URL parser a bit less permissive, so that non-breaking
58 spaces and commas are not included as part of URL. Thanks nAS for fixing.
59 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
60 David Hirtz for reporting.
61 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
64 4.5.0, released 2013-02-17
65 # Fix bug where stacked attribute transforms clobber each other;
66 this also means it's no longer possible to override attribute
67 transforms in later modules. No internal code was using this
68 but this may break some clients.
69 # We now use SHA-1 to identify cached definitions, instead of MD5.
70 ! Support display:inline-block
71 ! Support for more white-space CSS values.
72 ! Permit underscores in font families
73 ! Support for page-break-* CSS3 properties when proprietary properties
75 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
76 SGML excludes checking. If HTML Purifier is removing too much text
77 and you don't care about full standards compliance, try setting this to
79 - Use prepend for SPL autoloading on PHP 5.3 and later.
80 - Fix bug with nofollow transform when pre-existing rel exists.
81 - Fix bug where background:url() always gets lower-cased
82 (but not background-image:url())
83 - Fix bug with non lower-case color names in HTML
84 - Fix bug where data URI validation doesn't remove temporary files.
85 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
86 - Don't remove certain empty tags on RemoveEmpty.
88 4.4.0, released 2012-01-18
89 # Removed PEARSax3 handler.
90 # URI.Munge now munges URIs inside the same host that go from https
91 to http. Reported by Neike Taika-Tessaro.
92 # Core.EscapeNonASCIICharacters now always transforms entities to
93 entities, even if target encoding is UTF-8.
94 # Tighten up selector validation in ExtractStyleBlocks.
95 Non-syntactically valid selectors are now rejected, along with
96 some of the more obscure ones such as attribute selectors, the
97 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
98 ID and class selectors now work properly with the relevant
99 configuration attributes. Also, mute errors when parsing CSS
100 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
101 ! Added support for 'scope' attribute on tables.
102 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
103 ! Properly handle sub-lists directly nested inside of lists in
104 a standards compliant way, by moving them into the preceding <li>
105 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
106 limited allowed comments in untrusted situations.
107 ! Implement iframes, and allow them to be used in untrusted mode with
108 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
109 <brad.froehle@gmail.com> for submitting an initial version of the patch.
110 ! The Forms module now works properly for transitional doctypes.
111 ! Added support for internationalized domain names. You need the PEAR
112 Net_IDNA2 module to be in your path; if it is installed, ensure the
113 class can be loaded and then set %Core.EnableIDNA to true.
114 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
115 <yramirez-htmlpurifier@adicio.com> for reporting.
116 - Explicitly initialize anonModule variable to null.
117 - Do not duplicate nofollow if already present. Thanks 178
119 - Do not add nofollow if hostname matches our current host. Thanks 178
120 for reporting, and Neike Taika-Tessaro for helping diagnose.
121 - Do not unset parser variable; this fixes intermittent serialization
122 problems. Thanks Neike Taika-Tessaro for reporting, bill
123 <10010tiger@gmail.com> for diagnosing.
124 - Fix iconv truncation bug, where non-UTF-8 target encodings see
125 output truncated after around 8000 characters. Thanks Jörg Ludwig
126 <joerg.ludwig@iserv.eu> for reporting.
127 - Fix broken table content model for XHTML1.1 (and also earlier
128 versions, although the W3C validator doesn't catch those violations).
129 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
131 4.3.0, released 2011-03-27
132 # Fixed broken caching of customized raw definitions, but requires an
133 API change. The old API still works but will emit a warning,
134 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
135 for how to upgrade your code.
136 # Protect against Internet Explorer innerHTML behavior by specially
137 treating attributes with backticks but no angled brackets, quotes or
138 spaces. This constitutes a slight semantic change, which can be
139 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
141 # Protect against cssText/innerHTML by restricting allowed characters
142 used in fonts further than mandated by the specification and encoding
143 some extra special characters in URLs. Reported by Neike
144 Taika-Tessaro and Mario Heiderich.
145 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
146 ! More types of SPL autoloaders allowed on later versions of PHP.
147 ! Implementations for position, top, left, right, bottom, z-index
148 when %CSS.Trusted is on.
149 ! Add %Cache.SerializerPermissions option for custom serializer
150 directory/file permissions
151 ! Fix longstanding bug in Flash support for non-IE browsers, and
152 allow more wmode attributes.
153 ! Add %CSS.AllowedFonts to restrict permissible font names.
154 - Switch to an iterative traversal of the DOM, which prevents us
155 from running out of stack space for deeply nested documents.
156 Thanks Maxim Krizhanovsky for contributing a patch.
157 - Make removal of conditional IE comments ungreedy; thanks Bernd
159 - Escape CDATA before removing Internet Explorer comments.
160 - Fix removal of id attributes under certain conditions by ensuring
161 armor attributes are preserved when recreating tags.
162 - Check if schema.ser was corrupted.
163 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
164 This safety check is only done for HTMLPurifier.auto.php; if you
165 are using standalone or the specialized includes files, you're
166 expected to know what you're doing.
167 - Stop repeatedly writing the cache file after I'm done customizing a
168 raw definition. Reported by ajh.
169 - Switch to using require_once in the Bootstrap to work around bad
170 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
171 - Fix URI handling when hostname is missing but scheme is present.
172 Reported by Neike Taika-Tessaro.
173 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
175 - Fix harmless notice from indexing into empty string. Thanks Matthijs
176 Kooijman <matthijs@stdin.nl> for reporting.
177 - Don't autoclose no parent elements are able to support the element
178 that triggered the autoclose. In particular fixes strange behavior
179 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
180 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
182 4.2.0, released 2010-09-15
183 ! Added %Core.RemoveProcessingInstructions, which lets you remove
184 <? ... ?> statements.
185 ! Added %URI.DisableResources functionality; the directive originally
186 did nothing. Thanks David Rothstein for reporting.
187 ! Add documentation about configuration directive types.
188 ! Add %CSS.ForbiddenProperties configuration directive.
189 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
190 to utilize full-screen mode.
191 ! Add optional support for the <code>file</code> URI scheme, enable
192 by explicitly setting %URI.AllowedSchemes.
193 ! Add %Core.NormalizeNewlines options to allow turning off newline
195 - Fix improper handling of Internet Explorer conditional comments
196 by parser. Thanks zmonteca for reporting.
197 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
198 Thanks sidepodcast for the fix.
199 - Warn if an element is allowed, but an attribute it requires is
202 4.1.1, released 2010-05-31
203 - Fix undefined index warnings in maintenance scripts.
204 - Fix bug in DirectLex for parsing elements with a single attribute
206 - Rewrite CSS output logic for font-family and url(). Thanks Mario
207 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
208 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
209 - Emit an error for CollectErrors if a body is extracted
210 - Fix bug where in background-position for center keyword handling.
211 - Fix infinite loop when a wrapper element is inserted in a context
212 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
213 - Remove +x bit and shebang from index.php; only supported mode is to
214 explicitly call it with php.
215 - Make test script less chatty when log_errors is on.
217 4.1.0, released 2010-04-26
218 ! Support proprietary height attribute on table element
219 ! Support YouTube slideshows that contain /cp/ in their URL.
220 ! Support for data: URI scheme; not enabled by default, add it using
222 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
223 ! Support for Internet Explorer compatibility with %HTML.SafeObject
224 using %Output.FlashCompat.
225 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
226 - Always quote the insides of url(...) in CSS.
228 4.0.0, released 2009-07-07
229 # APIs for ConfigSchema subsystem have substantially changed. See
230 docs/dev-config-bcbreaks.txt for details; in essence, anything that
231 had both namespace and directive now have a single unified key.
232 # Some configuration directives were renamed, specifically:
233 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
234 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
235 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
236 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
237 As usual, the old directive names will still work, but will throw E_NOTICE
239 # The allowed values for class have been relaxed to allow all of CDATA for
240 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
241 %Attr.ClassUseCDATA to false.
242 # Instead of appending the content model to an old content model, a blank
243 element will replace the old content model. You can use #SUPER to get
244 the old content model.
245 ! More robust support for name="" and id=""
246 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
247 configuration, and have changes to that configuration be propagated
248 to all of its children.
249 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
250 the name attribute when set. Use with care. Thanks Ian Cook for
252 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
253 tags that contain non-breaking spaces as well other whitespace. You
254 can also modify which tags should have maintained with
255 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
256 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
257 classes users can use to a specified finite set of classes, and
258 %Attr.ForbiddenClasses, which is the logical inverse.
259 ! You can now maintain your own configuration schema directories by
260 creating a config-schema.php file or passing an extra argument. Check
261 docs/dev-config-schema.html for more details.
262 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
263 your configuration in a compact serial file, which you can unserialize
264 and use directly without having to go through the overhead of setup.
265 - Fix bug where URIDefinition would not get cleared if it's directives got
267 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
268 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
269 - Make %URI.Munge not apply to links that have the same host as your host.
270 - Prevent stray </body> tag from truncating output, if a second </body>
272 . Created script maintenance/rename-config.php for renaming a configuration
273 directive while maintaining its alias. This script does not change source code.
274 . Implement namespace locking for definition construction, to prevent
275 bugs where a directive is used for definition construction but is not
276 used to construct the cache hash.
278 3.3.0, released 2009-02-16
279 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
280 ! Implement generic property list classess
281 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
282 does not do the "right thing" with characters not supported in the output
284 - Spellcheck UTF-8: The Secret To Character Encoding
285 - Fix improper removal of the contents of elements with only whitespace. Thanks
286 Eric Wald for reporting.
287 - Fix broken test suite in versions of PHP without spl_autoload_register()
288 - Fix degenerate case with YouTube filter involving double hyphens.
289 Thanks Pierre Attar for reporting.
290 - Fix YouTube rendering problem on certain versions of Firefox.
291 - Fix CSSDefinition Printer problems with decorators
292 - Add text parameter to unit tests, forces text output
293 . Add verbose mode to command line test runner, use (--verbose)
294 . Turn on unit tests for UnitConverter
295 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
296 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
298 . Removed trailing whitespace from all text files, see
299 remote-trailing-whitespace.php maintenance script.
300 . Convert configuration to use property list backend.
302 3.2.0, released 2008-10-31
303 # Using %Core.CollectErrors forces line number/column tracking on, whereas
304 previously you could theoretically turn it off.
305 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
306 use handleEnd() instead.
307 ! %Output.AttrSort for when you need your attributes in alphabetical order to
308 deal with a bug in FCKEditor. Requested by frank farmer.
309 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
310 ! Proper support for name attribute. It is now allowed and equivalent to the id
311 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
312 is heavy (for all doctypes).
313 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
314 use on hand-written HTML.
315 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
316 the strategy to be used, standalone, on untrusted input.
317 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
318 processing of left angled brackets in smileys and other whatnot.
319 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
320 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
321 the --only-phpt parameter, although for backwards-compatibility the flag
323 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
324 Users who are not performing inbound filtering, this may seem a little
325 useless, but as a bonus, the test suite and handling of edge cases is also
327 ! Experimental implementation of forms for %HTML.Trusted
328 ! Track column numbers when maintain line numbers is on
329 ! Proprietary 'background' attribute on table-related elements converted into
330 corresponding CSS. Thanks Fusemail for sponsoring this feature!
331 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
333 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
334 time of operation varies slightly from notifyEnd() as *all* end tokens are
335 processed by the injector before they are subject to the well-formedness rules.
336 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
337 basename of image when not present.
338 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
339 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
340 the other involving an undefined $is_folder error.
341 - Throw error when %Core.Encoding is set to a spurious value. Previously,
342 this errored silently and returned false.
343 - Redirected stderr to stdout for flush error output.
344 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
346 - Do not re-munge URL if the output URL has the same host as the input URL.
348 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
349 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
350 - Fix bug with inline elements in blockquotes conflicting with strict doctype
351 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
352 - Fix bug where dots and double-dots in absolute URLs without hostname were
353 not collapsed by URIFilter_MakeAbsolute.
354 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
355 by reordering their addition.
356 - Will now throw exception on many error conditions during lexer creation; also
357 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
359 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
360 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
361 Reported by David Morton.
362 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
363 for more interesting filter-backtracking
364 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
365 index to reprocess tokens.
366 . StringHashParser now allows for multiline sections with "empty" content;
367 previously the section would remain undefined.
368 . Added --quick option to multitest.php, which tests only the most recent
369 release for each series.
370 . Added --distro option to multitest.php, which accepts either 'normal' or
371 'standalone'. This supercedes --exclude-normal and --exclude-standalone
373 3.1.1, released 2008-06-19
374 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
375 In order to enable this again, please set %URI.MungeResources to true.
376 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
377 and height/width HTML with %HTML.MaxImgLength.
378 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
379 for sponsoring this feature. Check out the corresponding documentation
380 for details. (Att Nightly testers: The API for this feature changed before
381 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
382 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
383 ! Implemented post URI filtering. Set member variable $post to true to set
385 ! Allow modules to define injectors via $info_injector. Injectors are
386 automatically disabled if injector's needed elements are not found.
387 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
388 Thanks Chris for sponsoring. If you've been using ad hoc code from the
389 forums, PLEASE use this instead.
390 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
391 embedded, tag name, attribute name, CSS property name). See %URI.Munge
392 for more details. Requested by Jochem Blok.
393 - Disable percent height/width attributes for img.
394 - AttrValidator operations are now atomic; updates to attributes are not
395 manifest in token until end of operations. This prevents naughty internal
396 code from directly modifying CurrentToken when they're not supposed to.
397 This semantics change was requested by frank farmer.
398 - Percent encoding checks enabled for URI query and fragment
399 - Fix stray backslashes in font-family; CSS Unicode character escapes are
400 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
402 - Improve parseCDATA algorithm to take into account newline normalization
403 - Account for browser confusion between Yen character and backslash in
404 Shift_JIS encoding. This fix generalizes to any other encoding which is not
405 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
406 - Fix missing configuration parameter in Generator calls. Thanks vs for the
408 - Improved adherence to Unicode by checking for non-character codepoints.
409 Thanks Geoffrey Sneddon for reporting. This may result in degraded
410 performance for extremely large inputs.
411 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
413 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
414 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
416 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
417 to __construct($min, $max). __construct(true) is equivalent to
419 . Added HTMLPurifier_AttrDef_Switch class
420 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
421 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
422 get this called with the configuration object. All modules now
423 use this rather than __construct(), although legacy code using constructors
424 will still work--the new format, however, lets modules access the
425 configuration object for HTML namespace dependant tweaks.
426 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
427 . ConfigSchema data-structure heavily optimized; on average it uses a third
428 the memory it did previously. The interface has changed accordingly,
429 consult changes to HTMLPurifier_Config for details.
430 . Variable parsing types now are magic integers instead of strings
431 . Added benchmark for ConfigSchema
432 . HTMLPurifier_Generator requires $config and $context parameters. If you
433 don't know what they should be, use HTMLPurifier_Config::createDefault()
434 and new HTMLPurifier_Context().
435 . Printers now properly distinguish between output configuration, and
436 target configuration. This is not applicable to scripts using
437 the Printers for HTML Purifier related tasks.
438 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
439 fatal errors will ensue.
440 . URIFilter->prepare can return false in order to abort loading of the filter
441 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
442 an external resource.
443 . %URI.Munge functionality factored out into a post-filter class.
444 . Added CurrentCSSProperty context variable during CSS validation
446 3.1.0, released 2008-05-18
447 # Unnecessary references to objects (vestiges of PHP4) removed from method
448 signatures. The following methods do not need references when assigning from
449 them and will result in E_STRICT errors if you try:
450 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
451 + HTMLPurifier_ConfigSchema::instance()
452 + HTMLPurifier_DefinitionCacheFactory::instance()
453 + HTMLPurifier_DefinitionCacheFactory->create()
454 + HTMLPurifier_DoctypeRegistry->register()
455 + HTMLPurifier_DoctypeRegistry->get()
456 + HTMLPurifier_HTMLModule->addElement()
457 + HTMLPurifier_HTMLModule->addBlankElement()
458 + HTMLPurifier_LanguageFactory::instance()
459 # Printer_ConfigForm's get*() functions were static-ified
460 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
461 form of tag@attr, NOT tag.attr (which will throw an error and won't do
462 anything). This is for forwards compatibility with XML; you'd do best
463 to migrate an %HTML.AllowedAttributes directives to this syntax too.
464 ! Allow index to be false for config from form creation
465 ! Added HTMLPurifier::VERSION constant
466 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
467 and allows for version numbers like "3.1.0-dev".
468 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
469 ! HTML Purifier's URI handling is a lot more robust, with much stricter
470 validation checks and better percent encoding handling. Thanks Gareth Heyes
471 for indicating security vulnerabilities from lax percent encoding.
472 ! Bootstrap autoloader deals more robustly with classes that don't exist,
473 preventing class_exists($class, true) from barfing.
474 - InterchangeBuilder now alphabetizes its lists
475 - Validation error in configdoc output fixed
476 - Iconv and other encoding errors muted even with custom error handlers that

501 3.1.0rc1, released 2008-04-22
502 # Autoload support added. Internal require_once's removed in favor of an
503 explicit require list or autoloading. To use HTML Purifier,
504 you must now either use HTMLPurifier.auto.php
505 or HTMLPurifier.includes.php; setting the include path and including
506 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
507 as well to register our autoload handler (or modify your autoload function
508 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
509 HTMLPurifier.safe-includes.php for a less performance friendly but more
510 user-friendly library load.
511 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
512 information is stored in the ConfigSchema directory, and the
513 maintenance/generate-schema-cache.php generates the schema.ser file, which
514 is now instantiated. Support for userland schema changes coming soon!
515 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
516 alias; to get rid of these errors just modify your configuration to use
517 the new directive name.
518 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
519 enabled using %Filter.$filter_name or by setting your own filters using
521 # Directive-level safety properties superceded in favor of module-level
522 safety. Internal method HTMLModule->addElement() has changed, although
523 the externally visible HTMLDefinition->addElement has *not* changed.
524 ! Extra utility classes for testing and non-library operations can
525 be found in extras/. Specifically, these are FSTools and ConfigDoc.

650 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
651 to better communicate its purpose

673 $config->set('Core', 'LexerImpl', 'PH5P');
674 Note that this Lexer introduces some classes not in the HTMLPurifier
675 namespace. Also, this is PHP5 only.
676 ! CSS property border-spacing implemented
677 - Fix non-visible parsing error in DirectLex with empty tags that have
678 slashes inside attribute values.
679 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
680 accepted as valid CSS. Usually non-visible, because this styling is the
681 default for tables in most browsers. Thanks Brett Zamir for pointing
683 - Fix validation errors in configuration form
684 - Hammer out a bunch of edge-case bugs in the standalone distribution
685 - Inclusion reflection removed from URISchemeRegistry; you must manually

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

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

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

762 linkify your HTML input by setting %AutoFormat.AutoParagraph and
763 %AutoFormat.Linkify to true
764 ! Newlines normalized internally, and then converted back to the
765 value of PHP_EOL. If this is not desired, set your newline format
766 using %Output.Newline.
767 ! Beta error collection, messages are implemented for the most generic
768 cases involving Lexing or Strategies
769 - Clean up special case code for <script> tags

803 # Completely refactored HTMLModuleManager, decentralizing safety
805 # Transform modules changed to Tidy modules, which offer more flexibility
806 and better modularization

811 # New compact syntax for AttrDef objects that can be used to instantiate
812 new objects via make()
813 # Definitions (esp. HTMLDefinition) are now cached for a significant
814 performance boost. You can disable caching by setting %Core.DefinitionCache

983 . Standardized all attribute handling variables to attr, made it plural
985 1.3.0, released 2006-11-26
986 # Invalid images are now removed, rather than replaced with a dud
987 <img src="" alt="Invalid image" />. Previous behavior can be restored
988 with new directive %Core.RemoveInvalidImg set to false.
989 ! (X)HTML Strict now supported
990 + Transparently handles inline elements in block context (blockquote)
991 ! Added GET method to demo for easier validation, added 50kb max input size
992 ! New directive %HTML.BlockWrapper, for block-ifying inline elements
993 ! New directive %HTML.Parent, allows you to only allow inline content
994 ! New directives %HTML.AllowedElements and %HTML.AllowedAttributes to let
995 users narrow the set of allowed tags
996 ! <li value="4"> and <ul start="2"> now allowed in loose mode
997 ! New directives %URI.DisableExternalResources and %URI.DisableResources
998 ! New directive %Attr.DisableURI, which eliminates all hyperlinking
999 ! New directive %URI.Munge, munges URI so you can use some sort of redirector
1000 service to avoid PageRank leaks or warn users that they are exiting your site.
1001 ! Added spiffy new smoketest printDefinition.php, which lets you twiddle with
1002 the configuration settings and see how the internal rules are affected.
1003 ! New directive %URI.HostBlacklist for blocking links to bad hosts.
1004 xssAttacks.php smoketest updated accordingly.

1016 1.2.0, released 2006-11-19
1017 # ID attributes now disabled by default. New directives:
1018 + %HTML.EnableAttrID - restores old behavior by allowing IDs
1019 + %Attr.IDPrefix - %Attr.IDBlacklist alternative that munges all user IDs
1020 so that they don't collide with your IDs
1021 + %Attr.IDPrefixLocal - Same as above, but for when there are multiple
1022 instances of user content on the page
1023 + Profuse documentation on how to use these available in docs/enduser-id.txt
