1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 3.1.0, unknown release date
13 # Autoload support added. Internal require_once's removed in favor of an
14 explicit require list or autoloading. To use HTML Purifier,
15 you must now either use HTMLPurifier.auto.php
16 or HTMLPurifier.includes.php; setting the include path and including
17 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
18 as well to register our autoload handler (or modify your autoload function
19 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
20 HTMLPurifier.safe-includes.php for a less performance friendly but more
21 user-friendly library load.
22 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
23 information is stored in the ConfigSchema directory, and the
24 maintenance/generate-schema-cache.php generates the schema.ser file, which
25 is now instantiated. Support for userland schema changes coming soon!
26 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
27 alias; to get rid of these errors just modify your configuration to use
28 the new directive name.
29 # Directive-level safety properties superceded in favor of module-level
30 safety. Internal method HTMLModule->addElement() has changed, although
31 the externally visible HTMLDefinition->addElement has *not* changed.
32 ! Extra utility classes for testing and non-library operations can
33 be found in extras/. Specifically, these are FSTools and ConfigDoc.
34 You may find a use for these in your own project, but right now they
35 are highly experimental and volatile.
36 ! Integration with PHPT allows for automated smoketests
37 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
38 by Chris. You can enable them with %HTML.Proprietary if your client
40 ! Support for !important CSS cascade modifier. By default, this will be stripped
41 from CSS, but you can enable it using %CSS.AllowImportant
42 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
44 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
45 Developer error (not enduser error) can cause these to be triggered.
46 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
47 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
48 mucking around with HTMLPurifier_CSSDefinition
49 ! ConfigDoc output has been enhanced with version and deprecation info.
50 - Autoclose now operates iteratively, i.e. <span><span><div> now has
51 both span tags closed.
52 - Various HTMLPurifier_Config convenience functions now accept another parameter
53 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
55 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
56 - Fix bug in ExtractStyleBlocks with comments in style tags
57 - Fix bug in comment parsing for DirectLex
58 - Flush output now displayed when in command line mode for unit tester
59 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
60 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
61 on the same element without emitting errors.
62 - Fixed fatal error in PH5P lexer with invalid tag names
63 . Plugins now get their own changelogs according to project conventions.
64 . Convert tokens to use instanceof, reducing memory footprint and
65 improving comparison speed.
66 . Dry runs now supported in SimpleTest; testing facilities improved
67 . Bootstrap class added for handling autoloading functionality
68 . Implemented recursive glob at FSTools->globr
69 . ConfigSchema now has instance methods for all corresponding define*
71 . A couple of new historical maintenance scripts were added.
72 . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
73 . tests/index.php can now be run from any directory.

76 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
77 . New --php=php flag added, allows PHP executable to be specified (command
79 . htmlpurifier_add_test() preferred method to translate test files in to
80 classes, because it handles PHPT files too.
81 . Debugger class is deprecated and will be removed soon.
82 . Command line argument parsing for testing scripts revamped, now --opt value
84 . Smoketests now cleanup after magic quotes
85 . Generator now can output comments (however, comments are still stripped
86 from HTML Purifier output)
87 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
88 HTMLPurifier_VarParser->parse()
89 . Integers auto-cast into float type by VarParser.
90 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
91 during cache generation
92 . Reordered script calls in maintenance/flush.php
93 . Command line scripts now honor exit codes
94 . When --flush fails in unit testers, abort tests and print message
95 . Improved documentation in docs/dev-flush.html about the maintenance scripts
96 . copy() methods removed in favor of clone keyword
98 3.0.0, released 2008-01-06
99 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained

102 + Visibility declarations added
103 + Constructor methods renamed to __construct()
104 + PHP4 reference cruft removed (in progress)
105 ! CSS properties are now case-insensitive

108 documents and cleaning their contents up. Requires the CSSTidy library
109 <http://csstidy.sourceforge.net/>. You can access the blocks with the
110 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
111 The output CSS can also be "scoped" for a specific element, use:
112 %Filter.ExtractStyleBlocksScope
113 ! Experimental support for some proprietary CSS attributes allowed:
114 opacity (and all of the browser-specific equivalents) and scrollbar colors.
115 Enable by setting %CSS.Proprietary to true.
116 - Colors missing # but in hex form will be corrected
117 - CSS Number algorithm improved
118 - Unit testing and multi-testing now on steroids: command lines,

124 . Multitest now has a file docblock
126 2.1.3, released 2007-11-05
127 ! tests/multitest.php allows you to test multiple versions by running
128 tests/index.php through multiple interpreters using `phpv` shell
129 script (you must provide this script!)
130 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
132 - Injector algorithm further refined: off-by-one error regarding skip
133 counts for dormant injectors fixed
134 - Corrective blockquote definition now enabled for HTML 4.01 Strict
135 - Fatal error when <img> tag (or any other element with required attributes)
136 has 'id' attribute fixed, thanks NykO18 for reporting
137 - Fix warning emitted when a non-supported URI scheme is passed to the
138 MakeAbsolute URIFilter, thanks NykO18 (again)
139 - Further refine AutoParagraph injector. Behavior inside of elements
140 allowing paragraph tags clarified: only inline content delimeted by
141 double newlines (not block elements) are paragraphed.
142 - Buggy treatment of end tags of elements that have required attributes
143 fixed (does not manifest on default tag-set)
144 - Spurious internal content reorganization error suppressed
145 - HTMLDefinition->addElement now returns a reference to the created
146 element object, as implied by the documentation
147 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
148 - Fix a theoretical class of infinite loops from DirectLex reported
150 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
152 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
153 HTMLDefinition errors, this may indicate problems with error-collecting
155 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
156 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
157 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
158 to better communicate its purpose
159 . Error unit tests can now specify the expectation of no errors. Future
160 iterations of the harness will be extremely strict about what errors
162 . Extend Injector hooks to allow for more powerful injector routines
163 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
165 . Doxygen configuration file updated, with minor improvements
166 . Test runner now checks for similarly named files in conf/ directory too.
167 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
169 . Maintenance script for generating PH5P patch added, original PH5P source
170 file also added under version control
171 . Full unit test runner script title made more descriptive with PHP version
172 . Updated INSTALL file to state that 4.3.7 is the earliest version we
175 2.1.2, released 2007-09-03
176 ! Implemented Object module for trusted users
177 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
179 require_once 'HTMLPurifier/Lexer/PH5P.php';
180 $config->set('Core', 'LexerImpl', 'PH5P');
181 Note that this Lexer introduces some classes not in the HTMLPurifier
182 namespace. Also, this is PHP5 only.
183 ! CSS property border-spacing implemented
184 - Fix non-visible parsing error in DirectLex with empty tags that have
185 slashes inside attribute values.
186 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
187 accepted as valid CSS. Usually non-visible, because this styling is the
188 default for tables in most browsers. Thanks Brett Zamir for pointing
190 - Fix validation errors in configuration form
191 - Hammer out a bunch of edge-case bugs in the standalone distribution
192 - Inclusion reflection removed from URISchemeRegistry; you must manually
193 include any new schema files you wish to use
194 - Numerous typo fixes in documentation thanks to Brett Zamir
195 . Unit test refactoring for one logical test per test function
196 . Config and context parameters in ComplexHarness deprecated: instead, edit
197 the $config and $context member variables
198 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
199 really make a difference, but is good for completeness sake
200 . merge-library.php script refactored for greater code reusability and
203 2.1.1, released 2007-08-04
204 - Fix show-stopper bug in %URI.MakeAbsolute functionality
205 - Fix PHP4 syntax error in standalone version
206 . Add prefix directory to include path for standalone, this prevents
207 other installations from clobbering the standalone's URI schemes
208 . Single test methods can be invoked by prefixing with __only
210 2.1.0, released 2007-08-02
211 # flush-htmldefinition-cache.php superseded in favor of a generic
212 flush-definition-cache.php script, you can clear a specific cache
213 by passing its name as a parameter to the script
214 ! Phorum mod implemented for HTML Purifier
215 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
216 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
217 for PHP4 (DirectLex).
218 ! Standalone file now available, which greatly reduces the amount of
219 includes (although there are still a few files that reside in the
221 ! Relative URIs can now be transformed into their absolute equivalents
222 using %URI.Base and %URI.MakeAbsolute

231 - XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
233 - Contents of <style> tags removed by default when tags are removed
234 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
235 for output cache invalidation
236 . ConfigForm printer now can retrieve CSS and JS files as strings, in
237 case HTML Purifier's directory is not publically accessible
238 . Introduce new text/itext configuration directive values: these represent
239 longer strings that would be more appropriately edited with a textarea
240 . Allow newlines to act as separators for lists, hashes, lookups and
242 . ConfigForm generates textareas instead of text inputs for lists, hashes,
243 lookups, text and itext fields
244 . Hidden element content removal genericized: %Core.HiddenElements can
245 be used to customize this behavior, by default <script> and <style> are
247 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
248 . Custom ChildDef added to default include list
249 . URIScheme reflection improved: will not attempt to include file if class
250 already exists. May clobber autoload, so I need to keep an eye on it
251 . ConfigSchema heavily optimized, will only collect information and validate
252 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
253 . AttrDef_URI unit tests and implementation refactored
254 . benchmarks/ directory now protected from public view with .htaccess file;
255 run the tests via command line
256 . URI scheme is munged off if there is no authority and the scheme is the
258 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
259 . Interface for URIScheme changed
260 . Generic URI object to hold components of URI added, most systems involved
261 in URI validation have been migrated to use it
262 . Custom filtering for URIs factored out to URIDefinition interface for
263 maximum extensibility
265 2.0.1, released 2007-06-27
266 ! Tag auto-closing now based on a ChildDef heuristic rather than a
267 manually set auto_close array; some behavior may change
268 ! Experimental AutoFormat functionality added: auto-paragraph and
269 linkify your HTML input by setting %AutoFormat.AutoParagraph and
270 %AutoFormat.Linkify to true
271 ! Newlines normalized internally, and then converted back to the
272 value of PHP_EOL. If this is not desired, set your newline format
273 using %Output.Newline.
274 ! Beta error collection, messages are implemented for the most generic
275 cases involving Lexing or Strategies
276 - Clean up special case code for <script> tags
277 - Reorder includes for DefinitionCache decorators, fixes a possible
279 - Fixed bug where manually modified definitions were not saved via cache

293 . DefinitionCache keys reordered to reflect precedence: version number,
294 hash, then revision number
295 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
296 . Interlinking in configuration documentation added using
297 Injector_PurifierLinkify
298 . Directives now keep track of aliases to themselves
299 . Error collector now requires a severity to be passed, use PHP's internal
300 error constants for this
301 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
302 much easier selective embedding of configuration values
303 . Doctype objects now accept public and system DTD identifiers
304 . %HTML.Doctype is now constrained by specific values, to specify a custom
305 doctype use new %HTML.CustomDoctype
306 . ConfigForm truncates long directives to keep the form small, and does
307 not re-output namespaces
309 2.0.0, released 2007-06-20
310 # Completely refactored HTMLModuleManager, decentralizing safety
312 # Transform modules changed to Tidy modules, which offer more flexibility
313 and better modularization
314 # Configuration object now finalizes itself when a read operation is
315 performed on it, ensuring that its internal state stays consistent.
316 To revert this behavior, you can set the $autoFinalize member variable
317 off, but it's not recommended.
318 # New compact syntax for AttrDef objects that can be used to instantiate
319 new objects via make()
320 # Definitions (esp. HTMLDefinition) are now cached for a significant
321 performance boost. You can disable caching by setting %Core.DefinitionCache
322 to null. You CANNOT edit raw definitions without setting the corresponding
323 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
324 # Contents between <script> tags are now completely removed if <script>
326 # Prototype-declarations for Lexer removed in favor of configuration
327 determination of Lexer implementations.

369 + size and noshade in hr
372 + align in caption, table, img and hr

378 images will hang around with an empty src
379 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
381 ! CSS property white-space now allows nowrap (supported in all modern

384 lang is now moved over to xml:lang.
385 ! Attribute transformation smoketest available at smoketests/attrTransform.php
386 ! Transformation of font's size attribute now handles super-large numbers
387 - Possibly fatal bug with __autoload() fixed in module manager
