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.
44 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
46 - Fix harmless notice from indexing into empty string. Thanks Matthijs
47 Kooijman <matthijs@stdin.nl> for reporting.
49 4.2.0, released 2010-09-15
50 ! Added %Core.RemoveProcessingInstructions, which lets you remove
52 ! Added %URI.DisableResources functionality; the directive originally
53 did nothing. Thanks David Rothstein for reporting.
54 ! Add documentation about configuration directive types.
55 ! Add %CSS.ForbiddenProperties configuration directive.
56 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
57 to utilize full-screen mode.
58 ! Add optional support for the <code>file</code> URI scheme, enable
59 by explicitly setting %URI.AllowedSchemes.
60 ! Add %Core.NormalizeNewlines options to allow turning off newline
62 - Fix improper handling of Internet Explorer conditional comments
63 by parser. Thanks zmonteca for reporting.
64 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
65 Thanks sidepodcast for the fix.
66 - Warn if an element is allowed, but an attribute it requires is
69 4.1.1, released 2010-05-31
70 - Fix undefined index warnings in maintenance scripts.
71 - Fix bug in DirectLex for parsing elements with a single attribute
73 - Rewrite CSS output logic for font-family and url(). Thanks Mario
74 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
75 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
76 - Emit an error for CollectErrors if a body is extracted
77 - Fix bug where in background-position for center keyword handling.
78 - Fix infinite loop when a wrapper element is inserted in a context
79 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
80 - Remove +x bit and shebang from index.php; only supported mode is to
81 explicitly call it with php.
82 - Make test script less chatty when log_errors is on.
84 4.1.0, released 2010-04-26
85 ! Support proprietary height attribute on table element
86 ! Support YouTube slideshows that contain /cp/ in their URL.
87 ! Support for data: URI scheme; not enabled by default, add it using
89 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
90 ! Support for Internet Explorer compatibility with %HTML.SafeObject
91 using %Output.FlashCompat.
92 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
93 - Always quote the insides of url(...) in CSS.
95 4.0.0, released 2009-07-07
96 # APIs for ConfigSchema subsystem have substantially changed. See
97 docs/dev-config-bcbreaks.txt for details; in essence, anything that
98 had both namespace and directive now have a single unified key.
99 # Some configuration directives were renamed, specifically:
100 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
101 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
102 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
103 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
104 As usual, the old directive names will still work, but will throw E_NOTICE
106 # The allowed values for class have been relaxed to allow all of CDATA for
107 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
108 %Attr.ClassUseCDATA to false.
109 # Instead of appending the content model to an old content model, a blank
110 element will replace the old content model. You can use #SUPER to get
111 the old content model.
112 ! More robust support for name="" and id=""
113 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
114 configuration, and have changes to that configuration be propagated
115 to all of its children.
116 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
117 the name attribute when set. Use with care. Thanks Ian Cook for
119 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
120 tags that contain non-breaking spaces as well other whitespace. You
121 can also modify which tags should have maintained with
122 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
123 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
124 classes users can use to a specified finite set of classes, and
125 %Attr.ForbiddenClasses, which is the logical inverse.
126 ! You can now maintain your own configuration schema directories by
127 creating a config-schema.php file or passing an extra argument. Check
128 docs/dev-config-schema.html for more details.
129 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
130 your configuration in a compact serial file, which you can unserialize
131 and use directly without having to go through the overhead of setup.
132 - Fix bug where URIDefinition would not get cleared if it's directives got
134 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
135 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
136 - Make %URI.Munge not apply to links that have the same host as your host.
137 - Prevent stray </body> tag from truncating output, if a second </body>
139 . Created script maintenance/rename-config.php for renaming a configuration
140 directive while maintaining its alias. This script does not change source code.
141 . Implement namespace locking for definition construction, to prevent
142 bugs where a directive is used for definition construction but is not
143 used to construct the cache hash.
145 3.3.0, released 2009-02-16
146 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
147 ! Implement generic property list classess
148 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
149 does not do the "right thing" with characters not supported in the output
151 - Spellcheck UTF-8: The Secret To Character Encoding
152 - Fix improper removal of the contents of elements with only whitespace. Thanks
153 Eric Wald for reporting.
154 - Fix broken test suite in versions of PHP without spl_autoload_register()
155 - Fix degenerate case with YouTube filter involving double hyphens.
156 Thanks Pierre Attar for reporting.
157 - Fix YouTube rendering problem on certain versions of Firefox.
158 - Fix CSSDefinition Printer problems with decorators
159 - Add text parameter to unit tests, forces text output
160 . Add verbose mode to command line test runner, use (--verbose)
161 . Turn on unit tests for UnitConverter
162 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
163 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
165 . Removed trailing whitespace from all text files, see
166 remote-trailing-whitespace.php maintenance script.
167 . Convert configuration to use property list backend.
169 3.2.0, released 2008-10-31
170 # Using %Core.CollectErrors forces line number/column tracking on, whereas
171 previously you could theoretically turn it off.
172 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
173 use handleEnd() instead.
174 ! %Output.AttrSort for when you need your attributes in alphabetical order to
175 deal with a bug in FCKEditor. Requested by frank farmer.
176 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
177 ! Proper support for name attribute. It is now allowed and equivalent to the id
178 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
179 is heavy (for all doctypes).
180 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
181 use on hand-written HTML.
182 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
183 the strategy to be used, standalone, on untrusted input.
184 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
185 processing of left angled brackets in smileys and other whatnot.
186 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
187 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
188 the --only-phpt parameter, although for backwards-compatibility the flag
190 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
191 Users who are not performing inbound filtering, this may seem a little
192 useless, but as a bonus, the test suite and handling of edge cases is also
194 ! Experimental implementation of forms for %HTML.Trusted
195 ! Track column numbers when maintain line numbers is on
196 ! Proprietary 'background' attribute on table-related elements converted into
197 corresponding CSS. Thanks Fusemail for sponsoring this feature!
198 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
200 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
201 time of operation varies slightly from notifyEnd() as *all* end tokens are
202 processed by the injector before they are subject to the well-formedness rules.
203 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
204 basename of image when not present.
205 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
206 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
207 the other involving an undefined $is_folder error.
208 - Throw error when %Core.Encoding is set to a spurious value. Previously,
209 this errored silently and returned false.
210 - Redirected stderr to stdout for flush error output.
211 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
213 - Do not re-munge URL if the output URL has the same host as the input URL.
215 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
216 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
217 - Fix bug with inline elements in blockquotes conflicting with strict doctype
218 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
219 - Fix bug where dots and double-dots in absolute URLs without hostname were
220 not collapsed by URIFilter_MakeAbsolute.
221 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
222 by reordering their addition.
223 - Will now throw exception on many error conditions during lexer creation; also
224 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
226 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
227 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
228 Reported by David Morton.
229 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
230 for more interesting filter-backtracking
231 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
232 index to reprocess tokens.
233 . StringHashParser now allows for multiline sections with "empty" content;
234 previously the section would remain undefined.
235 . Added --quick option to multitest.php, which tests only the most recent
236 release for each series.
237 . Added --distro option to multitest.php, which accepts either 'normal' or
238 'standalone'. This supercedes --exclude-normal and --exclude-standalone
240 3.1.1, released 2008-06-19
241 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
242 In order to enable this again, please set %URI.MungeResources to true.
243 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
244 and height/width HTML with %HTML.MaxImgLength.
245 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
246 for sponsoring this feature. Check out the corresponding documentation
247 for details. (Att Nightly testers: The API for this feature changed before
248 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
249 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
250 ! Implemented post URI filtering. Set member variable $post to true to set
252 ! Allow modules to define injectors via $info_injector. Injectors are
253 automatically disabled if injector's needed elements are not found.
254 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
255 Thanks Chris for sponsoring. If you've been using ad hoc code from the
256 forums, PLEASE use this instead.
257 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
258 embedded, tag name, attribute name, CSS property name). See %URI.Munge
259 for more details. Requested by Jochem Blok.
260 - Disable percent height/width attributes for img.
261 - AttrValidator operations are now atomic; updates to attributes are not
262 manifest in token until end of operations. This prevents naughty internal
263 code from directly modifying CurrentToken when they're not supposed to.
264 This semantics change was requested by frank farmer.
265 - Percent encoding checks enabled for URI query and fragment
266 - Fix stray backslashes in font-family; CSS Unicode character escapes are
267 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
269 - Improve parseCDATA algorithm to take into account newline normalization
270 - Account for browser confusion between Yen character and backslash in
271 Shift_JIS encoding. This fix generalizes to any other encoding which is not
272 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
273 - Fix missing configuration parameter in Generator calls. Thanks vs for the
275 - Improved adherence to Unicode by checking for non-character codepoints.
276 Thanks Geoffrey Sneddon for reporting. This may result in degraded
277 performance for extremely large inputs.
278 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
280 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
281 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
283 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
284 to __construct($min, $max). __construct(true) is equivalent to
286 . Added HTMLPurifier_AttrDef_Switch class
287 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
288 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
289 get this called with the configuration object. All modules now
290 use this rather than __construct(), although legacy code using constructors
291 will still work--the new format, however, lets modules access the
292 configuration object for HTML namespace dependant tweaks.
293 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
294 . ConfigSchema data-structure heavily optimized; on average it uses a third
295 the memory it did previously. The interface has changed accordingly,
296 consult changes to HTMLPurifier_Config for details.
297 . Variable parsing types now are magic integers instead of strings
298 . Added benchmark for ConfigSchema
299 . HTMLPurifier_Generator requires $config and $context parameters. If you
300 don't know what they should be, use HTMLPurifier_Config::createDefault()
301 and new HTMLPurifier_Context().
302 . Printers now properly distinguish between output configuration, and
303 target configuration. This is not applicable to scripts using
304 the Printers for HTML Purifier related tasks.
305 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
306 fatal errors will ensue.
307 . URIFilter->prepare can return false in order to abort loading of the filter
308 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
309 an external resource.
310 . %URI.Munge functionality factored out into a post-filter class.
311 . Added CurrentCSSProperty context variable during CSS validation
313 3.1.0, released 2008-05-18
314 # Unnecessary references to objects (vestiges of PHP4) removed from method
315 signatures. The following methods do not need references when assigning from
316 them and will result in E_STRICT errors if you try:
317 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
318 + HTMLPurifier_ConfigSchema::instance()
319 + HTMLPurifier_DefinitionCacheFactory::instance()
320 + HTMLPurifier_DefinitionCacheFactory->create()
321 + HTMLPurifier_DoctypeRegistry->register()
322 + HTMLPurifier_DoctypeRegistry->get()
323 + HTMLPurifier_HTMLModule->addElement()
324 + HTMLPurifier_HTMLModule->addBlankElement()
325 + HTMLPurifier_LanguageFactory::instance()
326 # Printer_ConfigForm's get*() functions were static-ified
327 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
328 form of tag@attr, NOT tag.attr (which will throw an error and won't do
329 anything). This is for forwards compatibility with XML; you'd do best
330 to migrate an %HTML.AllowedAttributes directives to this syntax too.
331 ! Allow index to be false for config from form creation
332 ! Added HTMLPurifier::VERSION constant
333 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
334 and allows for version numbers like "3.1.0-dev".
335 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
336 ! HTML Purifier's URI handling is a lot more robust, with much stricter
337 validation checks and better percent encoding handling. Thanks Gareth Heyes
338 for indicating security vulnerabilities from lax percent encoding.
339 ! Bootstrap autoloader deals more robustly with classes that don't exist,
340 preventing class_exists($class, true) from barfing.
341 - InterchangeBuilder now alphabetizes its lists
342 - Validation error in configdoc output fixed
343 - Iconv and other encoding errors muted even with custom error handlers that
344 do not honor error_reporting
345 - Add protection against imagecrash attack with CSS height/width
346 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
347 - Fixed and revamped broken ConfigForm smoketest
348 - Bug with bool/null fields in Printer_ConfigForm fixed
349 - Bug with global forbidden attributes fixed
350 - Improved error messages for allowed and forbidden HTML elements and attributes
351 - Missing (or null) in configdoc documentation restored
352 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
353 of DOM), HTML Purifier punts to DirectLex
354 - Fatal error with unserialization of ScriptRequired
355 - Created directories are now chmod'ed properly
356 - Fixed bug with fallback languages in LanguageFactory
357 - Standalone testing setup properly with autoload
358 . Out-of-date documentation revised
359 . UTF-8 encoding check optimization as suggested by Diego
360 . HTMLPurifier_Error removed in favor of exceptions
361 . More copy() function removed; should use clone instead
362 . More extensive unit tests for HTMLDefinition
363 . assertPurification moved to central harness
364 . HTMLPurifier_Generator accepts $config and $context parameters during
365 instantiation, not runtime
366 . Double-quotes outside of attribute values are now unescaped
368 3.1.0rc1, released 2008-04-22
369 # Autoload support added. Internal require_once's removed in favor of an
370 explicit require list or autoloading. To use HTML Purifier,
371 you must now either use HTMLPurifier.auto.php
372 or HTMLPurifier.includes.php; setting the include path and including
373 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
374 as well to register our autoload handler (or modify your autoload function
375 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
376 HTMLPurifier.safe-includes.php for a less performance friendly but more
377 user-friendly library load.
378 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
379 information is stored in the ConfigSchema directory, and the
380 maintenance/generate-schema-cache.php generates the schema.ser file, which
381 is now instantiated. Support for userland schema changes coming soon!
382 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
383 alias; to get rid of these errors just modify your configuration to use
384 the new directive name.
385 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
386 enabled using %Filter.$filter_name or by setting your own filters using
388 # Directive-level safety properties superceded in favor of module-level
389 safety. Internal method HTMLModule->addElement() has changed, although
390 the externally visible HTMLDefinition->addElement has *not* changed.
391 ! Extra utility classes for testing and non-library operations can
392 be found in extras/. Specifically, these are FSTools and ConfigDoc.
393 You may find a use for these in your own project, but right now they
394 are highly experimental and volatile.
395 ! Integration with PHPT allows for automated smoketests
396 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
397 by Chris. You can enable them with %HTML.Proprietary if your client
399 ! Support for !important CSS cascade modifier. By default, this will be stripped
400 from CSS, but you can enable it using %CSS.AllowImportant
401 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
403 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
404 Developer error (not enduser error) can cause these to be triggered.
405 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
406 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
407 mucking around with HTMLPurifier_CSSDefinition
408 ! ConfigDoc output has been enhanced with version and deprecation info.
409 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
410 - Autoclose now operates iteratively, i.e. <span><span><div> now has
411 both span tags closed.
412 - Various HTMLPurifier_Config convenience functions now accept another parameter
413 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
415 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
416 - Fix bug in ExtractStyleBlocks with comments in style tags
417 - Fix bug in comment parsing for DirectLex
418 - Flush output now displayed when in command line mode for unit tester
419 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
420 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
421 on the same element without emitting errors.
422 - Fixed fatal error in PH5P lexer with invalid tag names
423 . Plugins now get their own changelogs according to project conventions.
424 . Convert tokens to use instanceof, reducing memory footprint and
425 improving comparison speed.
426 . Dry runs now supported in SimpleTest; testing facilities improved
427 . Bootstrap class added for handling autoloading functionality
428 . Implemented recursive glob at FSTools->globr
429 . ConfigSchema now has instance methods for all corresponding define*
431 . A couple of new historical maintenance scripts were added.
432 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
433 . tests/index.php can now be run from any directory.
434 . HTMLPurifier_Token subclasses split into seperate files
435 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
436 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
437 . New --php=php flag added, allows PHP executable to be specified (command
439 . htmlpurifier_add_test() preferred method to translate test files in to
440 classes, because it handles PHPT files too.
441 . Debugger class is deprecated and will be removed soon.
442 . Command line argument parsing for testing scripts revamped, now --opt value
444 . Smoketests now cleanup after magic quotes
445 . Generator now can output comments (however, comments are still stripped
446 from HTML Purifier output)
447 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
448 HTMLPurifier_VarParser->parse()
449 . Integers auto-cast into float type by VarParser.
450 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
451 during cache generation
452 . Reordered script calls in maintenance/flush.php
453 . Command line scripts now honor exit codes
454 . When --flush fails in unit testers, abort tests and print message
455 . Improved documentation in docs/dev-flush.html about the maintenance scripts
456 . copy() methods removed in favor of clone keyword
458 3.0.0, released 2008-01-06
459 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
460 until PHP 4 is completely deprecated, but no new features will be added
462 + Visibility declarations added
463 + Constructor methods renamed to __construct()
464 + PHP4 reference cruft removed (in progress)
465 ! CSS properties are now case-insensitive
466 ! DefinitionCacheFactory now can register new implementations
467 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
468 documents and cleaning their contents up. Requires the CSSTidy library
469 <http://csstidy.sourceforge.net/>. You can access the blocks with the
470 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
471 The output CSS can also be "scoped" for a specific element, use:
472 %Filter.ExtractStyleBlocksScope
473 ! Experimental support for some proprietary CSS attributes allowed:
474 opacity (and all of the browser-specific equivalents) and scrollbar colors.
475 Enable by setting %CSS.Proprietary to true.
476 - Colors missing # but in hex form will be corrected
477 - CSS Number algorithm improved
478 - Unit testing and multi-testing now on steroids: command lines,

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

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

542 namespace. Also, this is PHP5 only.
543 ! CSS property border-spacing implemented
544 - Fix non-visible parsing error in DirectLex with empty tags that have
545 slashes inside attribute values.
546 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
547 accepted as valid CSS. Usually non-visible, because this styling is the
548 default for tables in most browsers. Thanks Brett Zamir for pointing
550 - Fix validation errors in configuration form
551 - Hammer out a bunch of edge-case bugs in the standalone distribution
552 - Inclusion reflection removed from URISchemeRegistry; you must manually
553 include any new schema files you wish to use
554 - Numerous typo fixes in documentation thanks to Brett Zamir
555 . Unit test refactoring for one logical test per test function
556 . Config and context parameters in ComplexHarness deprecated: instead, edit
557 the $config and $context member variables
558 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
559 really make a difference, but is good for completeness sake
560 . merge-library.php script refactored for greater code reusability and
563 2.1.1, released 2007-08-04
564 - Fix show-stopper bug in %URI.MakeAbsolute functionality

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

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

627 manually set auto_close array; some behavior may change
628 ! Experimental AutoFormat functionality added: auto-paragraph and
629 linkify your HTML input by setting %AutoFormat.AutoParagraph and
630 %AutoFormat.Linkify to true
631 ! Newlines normalized internally, and then converted back to the
632 value of PHP_EOL. If this is not desired, set your newline format
633 using %Output.Newline.
634 ! Beta error collection, messages are implemented for the most generic
635 cases involving Lexing or Strategies
636 - Clean up special case code for <script> tags

656 . Interlinking in configuration documentation added using
657 Injector_PurifierLinkify
658 . Directives now keep track of aliases to themselves

672 # Transform modules changed to Tidy modules, which offer more flexibility
673 and better modularization

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