1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.3.0, unknown release date
13 # Fixed broken caching of customized raw definitions, but requires an
14 API change. The old API still works but will emit a warning,
15 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
16 for how to upgrade your code.
17 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
18 ! More types of SPL autoloaders allowed on later versions of PHP.
19 ! Implementations for position, top, left, right, bottom, z-index
20 when %CSS.Trusted is on.
21 ! Add %Cache.SerializerPermissions option for custom serializer
22 directory/file permissions
23 ! Fix longstanding bug in Flash support for non-IE browsers, and
24 allow more wmode attributes.
25 - Switch to an iterative traversal of the DOM, which prevents us
26 from running out of stack space for deeply nested documents.
27 Thanks Maxim Krizhanovsky for contributing a patch.
28 - Make removal of conditional IE comments ungreedy; thanks Bernd
30 - Escape CDATA before removing Internet Explorer comments.
31 - Fix removal of id attributes under certain conditions by ensuring
32 armor attributes are preserved when recreating tags.
33 - Check if schema.ser was corrupted.
34 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
35 This safety check is only done for HTMLPurifier.auto.php; if you
36 are using standalone or the specialized includes files, you're
37 expected to know what you're doing.
38 - Stop repeatedly writing the cache file after I'm done customizing a
39 raw definition. Reported by ajh.
40 - Switch to using require_once in the Bootstrap to work around bad
41 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
42 - Fix URI handling when hostname is missing but scheme is present.
43 Reported by Neike Taika-Tessaro.
45 4.2.0, released 2010-09-15
46 ! Added %Core.RemoveProcessingInstructions, which lets you remove
48 ! Added %URI.DisableResources functionality; the directive originally
49 did nothing. Thanks David Rothstein for reporting.
50 ! Add documentation about configuration directive types.
51 ! Add %CSS.ForbiddenProperties configuration directive.
52 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
53 to utilize full-screen mode.
54 ! Add optional support for the <code>file</code> URI scheme, enable
55 by explicitly setting %URI.AllowedSchemes.
56 ! Add %Core.NormalizeNewlines options to allow turning off newline
58 - Fix improper handling of Internet Explorer conditional comments
59 by parser. Thanks zmonteca for reporting.
60 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
61 Thanks sidepodcast for the fix.
62 - Warn if an element is allowed, but an attribute it requires is
65 4.1.1, released 2010-05-31
66 - Fix undefined index warnings in maintenance scripts.
67 - Fix bug in DirectLex for parsing elements with a single attribute
69 - Rewrite CSS output logic for font-family and url(). Thanks Mario
70 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
71 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
72 - Emit an error for CollectErrors if a body is extracted
73 - Fix bug where in background-position for center keyword handling.
74 - Fix infinite loop when a wrapper element is inserted in a context
75 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
76 - Remove +x bit and shebang from index.php; only supported mode is to
77 explicitly call it with php.
78 - Make test script less chatty when log_errors is on.
80 4.1.0, released 2010-04-26
81 ! Support proprietary height attribute on table element
82 ! Support YouTube slideshows that contain /cp/ in their URL.
83 ! Support for data: URI scheme; not enabled by default, add it using
85 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
86 ! Support for Internet Explorer compatibility with %HTML.SafeObject
87 using %Output.FlashCompat.
88 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
89 - Always quote the insides of url(...) in CSS.
91 4.0.0, released 2009-07-07
92 # APIs for ConfigSchema subsystem have substantially changed. See
93 docs/dev-config-bcbreaks.txt for details; in essence, anything that
94 had both namespace and directive now have a single unified key.
95 # Some configuration directives were renamed, specifically:
96 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
97 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
98 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
99 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
100 As usual, the old directive names will still work, but will throw E_NOTICE
102 # The allowed values for class have been relaxed to allow all of CDATA for
103 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
104 %Attr.ClassUseCDATA to false.
105 # Instead of appending the content model to an old content model, a blank
106 element will replace the old content model. You can use #SUPER to get
107 the old content model.
108 ! More robust support for name="" and id=""
109 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
110 configuration, and have changes to that configuration be propagated
111 to all of its children.
112 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
113 the name attribute when set. Use with care. Thanks Ian Cook for
115 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
116 tags that contain non-breaking spaces as well other whitespace. You
117 can also modify which tags should have maintained with
118 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
119 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
120 classes users can use to a specified finite set of classes, and
121 %Attr.ForbiddenClasses, which is the logical inverse.
122 ! You can now maintain your own configuration schema directories by
123 creating a config-schema.php file or passing an extra argument. Check
124 docs/dev-config-schema.html for more details.
125 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
126 your configuration in a compact serial file, which you can unserialize
127 and use directly without having to go through the overhead of setup.
128 - Fix bug where URIDefinition would not get cleared if it's directives got
130 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
131 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
132 - Make %URI.Munge not apply to links that have the same host as your host.
133 - Prevent stray </body> tag from truncating output, if a second </body>
135 . Created script maintenance/rename-config.php for renaming a configuration
136 directive while maintaining its alias. This script does not change source code.
137 . Implement namespace locking for definition construction, to prevent
138 bugs where a directive is used for definition construction but is not
139 used to construct the cache hash.
141 3.3.0, released 2009-02-16
142 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
143 ! Implement generic property list classess
144 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
145 does not do the "right thing" with characters not supported in the output
147 - Spellcheck UTF-8: The Secret To Character Encoding
148 - Fix improper removal of the contents of elements with only whitespace. Thanks
149 Eric Wald for reporting.
150 - Fix broken test suite in versions of PHP without spl_autoload_register()
151 - Fix degenerate case with YouTube filter involving double hyphens.
152 Thanks Pierre Attar for reporting.
153 - Fix YouTube rendering problem on certain versions of Firefox.
154 - Fix CSSDefinition Printer problems with decorators
155 - Add text parameter to unit tests, forces text output
156 . Add verbose mode to command line test runner, use (--verbose)
157 . Turn on unit tests for UnitConverter
158 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
159 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
161 . Removed trailing whitespace from all text files, see
162 remote-trailing-whitespace.php maintenance script.
163 . Convert configuration to use property list backend.
165 3.2.0, released 2008-10-31
166 # Using %Core.CollectErrors forces line number/column tracking on, whereas
167 previously you could theoretically turn it off.
168 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
169 use handleEnd() instead.
170 ! %Output.AttrSort for when you need your attributes in alphabetical order to
171 deal with a bug in FCKEditor. Requested by frank farmer.
172 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
173 ! Proper support for name attribute. It is now allowed and equivalent to the id
174 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
175 is heavy (for all doctypes).
176 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
177 use on hand-written HTML.
178 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
179 the strategy to be used, standalone, on untrusted input.
180 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
181 processing of left angled brackets in smileys and other whatnot.
182 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
183 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
184 the --only-phpt parameter, although for backwards-compatibility the flag
186 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
187 Users who are not performing inbound filtering, this may seem a little
188 useless, but as a bonus, the test suite and handling of edge cases is also
190 ! Experimental implementation of forms for %HTML.Trusted
191 ! Track column numbers when maintain line numbers is on
192 ! Proprietary 'background' attribute on table-related elements converted into
193 corresponding CSS. Thanks Fusemail for sponsoring this feature!
194 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
196 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
197 time of operation varies slightly from notifyEnd() as *all* end tokens are
198 processed by the injector before they are subject to the well-formedness rules.
199 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
200 basename of image when not present.
201 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
202 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
203 the other involving an undefined $is_folder error.
204 - Throw error when %Core.Encoding is set to a spurious value. Previously,
205 this errored silently and returned false.
206 - Redirected stderr to stdout for flush error output.
207 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
209 - Do not re-munge URL if the output URL has the same host as the input URL.
211 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
212 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
213 - Fix bug with inline elements in blockquotes conflicting with strict doctype
214 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
215 - Fix bug where dots and double-dots in absolute URLs without hostname were
216 not collapsed by URIFilter_MakeAbsolute.
217 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
218 by reordering their addition.
219 - Will now throw exception on many error conditions during lexer creation; also
220 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
222 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
223 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
224 Reported by David Morton.
225 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
226 for more interesting filter-backtracking
227 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
228 index to reprocess tokens.
229 . StringHashParser now allows for multiline sections with "empty" content;
230 previously the section would remain undefined.
231 . Added --quick option to multitest.php, which tests only the most recent
232 release for each series.
233 . Added --distro option to multitest.php, which accepts either 'normal' or
234 'standalone'. This supercedes --exclude-normal and --exclude-standalone
236 3.1.1, released 2008-06-19
237 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
238 In order to enable this again, please set %URI.MungeResources to true.
239 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
240 and height/width HTML with %HTML.MaxImgLength.
241 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
242 for sponsoring this feature. Check out the corresponding documentation
243 for details. (Att Nightly testers: The API for this feature changed before
244 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
245 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
246 ! Implemented post URI filtering. Set member variable $post to true to set
248 ! Allow modules to define injectors via $info_injector. Injectors are
249 automatically disabled if injector's needed elements are not found.
250 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
251 Thanks Chris for sponsoring. If you've been using ad hoc code from the
252 forums, PLEASE use this instead.
253 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
254 embedded, tag name, attribute name, CSS property name). See %URI.Munge
255 for more details. Requested by Jochem Blok.
256 - Disable percent height/width attributes for img.
257 - AttrValidator operations are now atomic; updates to attributes are not
258 manifest in token until end of operations. This prevents naughty internal
259 code from directly modifying CurrentToken when they're not supposed to.
260 This semantics change was requested by frank farmer.
261 - Percent encoding checks enabled for URI query and fragment
262 - Fix stray backslashes in font-family; CSS Unicode character escapes are
263 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
265 - Improve parseCDATA algorithm to take into account newline normalization
266 - Account for browser confusion between Yen character and backslash in
267 Shift_JIS encoding. This fix generalizes to any other encoding which is not
268 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
269 - Fix missing configuration parameter in Generator calls. Thanks vs for the
271 - Improved adherence to Unicode by checking for non-character codepoints.
272 Thanks Geoffrey Sneddon for reporting. This may result in degraded
273 performance for extremely large inputs.
274 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
276 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
277 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
279 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
280 to __construct($min, $max). __construct(true) is equivalent to
282 . Added HTMLPurifier_AttrDef_Switch class
283 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
284 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
285 get this called with the configuration object. All modules now
286 use this rather than __construct(), although legacy code using constructors
287 will still work--the new format, however, lets modules access the
288 configuration object for HTML namespace dependant tweaks.
289 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
290 . ConfigSchema data-structure heavily optimized; on average it uses a third
291 the memory it did previously. The interface has changed accordingly,
292 consult changes to HTMLPurifier_Config for details.
293 . Variable parsing types now are magic integers instead of strings
294 . Added benchmark for ConfigSchema
295 . HTMLPurifier_Generator requires $config and $context parameters. If you
296 don't know what they should be, use HTMLPurifier_Config::createDefault()
297 and new HTMLPurifier_Context().
298 . Printers now properly distinguish between output configuration, and
299 target configuration. This is not applicable to scripts using
300 the Printers for HTML Purifier related tasks.
301 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
302 fatal errors will ensue.
303 . URIFilter->prepare can return false in order to abort loading of the filter
304 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
305 an external resource.
306 . %URI.Munge functionality factored out into a post-filter class.
307 . Added CurrentCSSProperty context variable during CSS validation
309 3.1.0, released 2008-05-18
310 # Unnecessary references to objects (vestiges of PHP4) removed from method
311 signatures. The following methods do not need references when assigning from
312 them and will result in E_STRICT errors if you try:
313 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
314 + HTMLPurifier_ConfigSchema::instance()
315 + HTMLPurifier_DefinitionCacheFactory::instance()
316 + HTMLPurifier_DefinitionCacheFactory->create()
317 + HTMLPurifier_DoctypeRegistry->register()
318 + HTMLPurifier_DoctypeRegistry->get()
319 + HTMLPurifier_HTMLModule->addElement()
320 + HTMLPurifier_HTMLModule->addBlankElement()
321 + HTMLPurifier_LanguageFactory::instance()
322 # Printer_ConfigForm's get*() functions were static-ified
323 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
324 form of tag@attr, NOT tag.attr (which will throw an error and won't do
325 anything). This is for forwards compatibility with XML; you'd do best
326 to migrate an %HTML.AllowedAttributes directives to this syntax too.
327 ! Allow index to be false for config from form creation
328 ! Added HTMLPurifier::VERSION constant
329 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
330 and allows for version numbers like "3.1.0-dev".
331 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
332 ! HTML Purifier's URI handling is a lot more robust, with much stricter
333 validation checks and better percent encoding handling. Thanks Gareth Heyes
334 for indicating security vulnerabilities from lax percent encoding.
335 ! Bootstrap autoloader deals more robustly with classes that don't exist,
336 preventing class_exists($class, true) from barfing.
337 - InterchangeBuilder now alphabetizes its lists
338 - Validation error in configdoc output fixed
339 - Iconv and other encoding errors muted even with custom error handlers that
340 do not honor error_reporting
341 - Add protection against imagecrash attack with CSS height/width
342 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
343 - Fixed and revamped broken ConfigForm smoketest
344 - Bug with bool/null fields in Printer_ConfigForm fixed
345 - Bug with global forbidden attributes fixed
346 - Improved error messages for allowed and forbidden HTML elements and attributes
347 - Missing (or null) in configdoc documentation restored
348 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
349 of DOM), HTML Purifier punts to DirectLex
350 - Fatal error with unserialization of ScriptRequired
351 - Created directories are now chmod'ed properly
352 - Fixed bug with fallback languages in LanguageFactory
353 - Standalone testing setup properly with autoload
354 . Out-of-date documentation revised
355 . UTF-8 encoding check optimization as suggested by Diego
356 . HTMLPurifier_Error removed in favor of exceptions
357 . More copy() function removed; should use clone instead
358 . More extensive unit tests for HTMLDefinition
359 . assertPurification moved to central harness
360 . HTMLPurifier_Generator accepts $config and $context parameters during
361 instantiation, not runtime
362 . Double-quotes outside of attribute values are now unescaped
364 3.1.0rc1, released 2008-04-22
365 # Autoload support added. Internal require_once's removed in favor of an
366 explicit require list or autoloading. To use HTML Purifier,
367 you must now either use HTMLPurifier.auto.php
368 or HTMLPurifier.includes.php; setting the include path and including
369 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
370 as well to register our autoload handler (or modify your autoload function
371 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
372 HTMLPurifier.safe-includes.php for a less performance friendly but more
373 user-friendly library load.
374 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
375 information is stored in the ConfigSchema directory, and the
376 maintenance/generate-schema-cache.php generates the schema.ser file, which
377 is now instantiated. Support for userland schema changes coming soon!
378 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
379 alias; to get rid of these errors just modify your configuration to use
380 the new directive name.
381 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
382 enabled using %Filter.$filter_name or by setting your own filters using
384 # Directive-level safety properties superceded in favor of module-level
385 safety. Internal method HTMLModule->addElement() has changed, although
386 the externally visible HTMLDefinition->addElement has *not* changed.
387 ! Extra utility classes for testing and non-library operations can
388 be found in extras/. Specifically, these are FSTools and ConfigDoc.
389 You may find a use for these in your own project, but right now they
390 are highly experimental and volatile.
391 ! Integration with PHPT allows for automated smoketests
392 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
393 by Chris. You can enable them with %HTML.Proprietary if your client
395 ! Support for !important CSS cascade modifier. By default, this will be stripped
396 from CSS, but you can enable it using %CSS.AllowImportant
397 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
399 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
400 Developer error (not enduser error) can cause these to be triggered.
401 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
402 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
403 mucking around with HTMLPurifier_CSSDefinition
404 ! ConfigDoc output has been enhanced with version and deprecation info.
405 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
406 - Autoclose now operates iteratively, i.e. <span><span><div> now has
407 both span tags closed.
408 - Various HTMLPurifier_Config convenience functions now accept another parameter
409 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
411 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
412 - Fix bug in ExtractStyleBlocks with comments in style tags
413 - Fix bug in comment parsing for DirectLex
414 - Flush output now displayed when in command line mode for unit tester
415 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
416 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
417 on the same element without emitting errors.
418 - Fixed fatal error in PH5P lexer with invalid tag names
419 . Plugins now get their own changelogs according to project conventions.
420 . Convert tokens to use instanceof, reducing memory footprint and
421 improving comparison speed.
422 . Dry runs now supported in SimpleTest; testing facilities improved
423 . Bootstrap class added for handling autoloading functionality
424 . Implemented recursive glob at FSTools->globr
425 . ConfigSchema now has instance methods for all corresponding define*
427 . A couple of new historical maintenance scripts were added.
428 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
429 . tests/index.php can now be run from any directory.
430 . HTMLPurifier_Token subclasses split into seperate files
431 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
432 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
433 . New --php=php flag added, allows PHP executable to be specified (command
435 . htmlpurifier_add_test() preferred method to translate test files in to
436 classes, because it handles PHPT files too.
437 . Debugger class is deprecated and will be removed soon.
438 . Command line argument parsing for testing scripts revamped, now --opt value
440 . Smoketests now cleanup after magic quotes
441 . Generator now can output comments (however, comments are still stripped
442 from HTML Purifier output)
443 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
444 HTMLPurifier_VarParser->parse()
445 . Integers auto-cast into float type by VarParser.
446 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
447 during cache generation
448 . Reordered script calls in maintenance/flush.php
449 . Command line scripts now honor exit codes
450 . When --flush fails in unit testers, abort tests and print message
451 . Improved documentation in docs/dev-flush.html about the maintenance scripts
452 . copy() methods removed in favor of clone keyword
454 3.0.0, released 2008-01-06
455 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
456 until PHP 4 is completely deprecated, but no new features will be added
458 + Visibility declarations added
459 + Constructor methods renamed to __construct()
460 + PHP4 reference cruft removed (in progress)
461 ! CSS properties are now case-insensitive
462 ! DefinitionCacheFactory now can register new implementations
463 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
464 documents and cleaning their contents up. Requires the CSSTidy library
465 <http://csstidy.sourceforge.net/>. You can access the blocks with the
466 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
467 The output CSS can also be "scoped" for a specific element, use:
468 %Filter.ExtractStyleBlocksScope
469 ! Experimental support for some proprietary CSS attributes allowed:
470 opacity (and all of the browser-specific equivalents) and scrollbar colors.
471 Enable by setting %CSS.Proprietary to true.
472 - Colors missing # but in hex form will be corrected
473 - CSS Number algorithm improved
474 - Unit testing and multi-testing now on steroids: command lines,
475 XML output, and other goodies now added.
476 . Unit tests for Injector improved
478 + HTMLPurifier_AttrDef_CSS_AlphaValue
479 + HTMLPurifier_AttrDef_CSS_Filter
480 . Multitest now has a file docblock
482 2.1.3, released 2007-11-05
483 ! tests/multitest.php allows you to test multiple versions by running
484 tests/index.php through multiple interpreters using `phpv` shell
485 script (you must provide this script!)

489 counts for dormant injectors fixed
490 - Corrective blockquote definition now enabled for HTML 4.01 Strict
491 - Fatal error when <img> tag (or any other element with required attributes)
492 has 'id' attribute fixed, thanks NykO18 for reporting
493 - Fix warning emitted when a non-supported URI scheme is passed to the
494 MakeAbsolute URIFilter, thanks NykO18 (again)
495 - Further refine AutoParagraph injector. Behavior inside of elements
496 allowing paragraph tags clarified: only inline content delimeted by
497 double newlines (not block elements) are paragraphed.
498 - Buggy treatment of end tags of elements that have required attributes
499 fixed (does not manifest on default tag-set)
500 - Spurious internal content reorganization error suppressed

512 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
513 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
514 to better communicate its purpose
515 . Error unit tests can now specify the expectation of no errors. Future
516 iterations of the harness will be extremely strict about what errors
518 . Extend Injector hooks to allow for more powerful injector routines

535 require_once 'HTMLPurifier/Lexer/PH5P.php';
536 $config->set('Core', 'LexerImpl', 'PH5P');
537 Note that this Lexer introduces some classes not in the HTMLPurifier
538 namespace. Also, this is PHP5 only.
539 ! CSS property border-spacing implemented
540 - Fix non-visible parsing error in DirectLex with empty tags that have
541 slashes inside attribute values.
542 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
543 accepted as valid CSS. Usually non-visible, because this styling is the
544 default for tables in most browsers. Thanks Brett Zamir for pointing
546 - Fix validation errors in configuration form
547 - Hammer out a bunch of edge-case bugs in the standalone distribution
548 - Inclusion reflection removed from URISchemeRegistry; you must manually
549 include any new schema files you wish to use
550 - Numerous typo fixes in documentation thanks to Brett Zamir
551 . Unit test refactoring for one logical test per test function
552 . Config and context parameters in ComplexHarness deprecated: instead, edit
553 the $config and $context member variables

555 really make a difference, but is good for completeness sake
556 . merge-library.php script refactored for greater code reusability and
559 2.1.1, released 2007-08-04
560 - Fix show-stopper bug in %URI.MakeAbsolute functionality

591 for output cache invalidation
592 . ConfigForm printer now can retrieve CSS and JS files as strings, in
593 case HTML Purifier's directory is not publically accessible
594 . Introduce new text/itext configuration directive values: these represent

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

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

608 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
609 . AttrDef_URI unit tests and implementation refactored

619 maximum extensibility
621 2.0.1, released 2007-06-27
622 ! Tag auto-closing now based on a ChildDef heuristic rather than a
623 manually set auto_close array; some behavior may change
624 ! Experimental AutoFormat functionality added: auto-paragraph and
625 linkify your HTML input by setting %AutoFormat.AutoParagraph and
626 %AutoFormat.Linkify to true
627 ! Newlines normalized internally, and then converted back to the
628 value of PHP_EOL. If this is not desired, set your newline format
629 using %Output.Newline.
630 ! Beta error collection, messages are implemented for the most generic
631 cases involving Lexing or Strategies
632 - Clean up special case code for <script> tags

652 . Interlinking in configuration documentation added using
653 Injector_PurifierLinkify
654 . Directives now keep track of aliases to themselves

666 # Completely refactored HTMLModuleManager, decentralizing safety
668 # Transform modules changed to Tidy modules, which offer more flexibility
669 and better modularization

675 new objects via make()
676 # Definitions (esp. HTMLDefinition) are now cached for a significant
677 performance boost. You can disable caching by setting %Core.DefinitionCache
