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)).
20 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
21 information is stored in the ConfigSchema directory, and the
22 maintenance/generate-schema-cache.php generates the schema.ser file, which
23 is now instantiated. Support for userland schema changes coming soon!
24 ! Extra utility classes for testing and non-library operations can
25 be found in extras/. Specifically, these are FSTools and ConfigDoc.
26 You may find a use for these in your own project, but right now they
27 are highly experimental and volatile.
28 ! Integration with PHPT allows for automated smoketests
29 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
30 by Chris. You can enable them with %HTML.Proprietary if your client
32 ! Support for !important CSS cascade modifier. By default, this will be stripped
33 from CSS, but you can enable it using %CSS.AllowImportant
34 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
36 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
37 Developer error (not enduser error) can cause these to be triggered.
38 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
39 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
40 mucking around with HTMLPurifier_CSSDefinition
41 - Autoclose now operates iteratively, i.e. <span><span><div> now has
42 both span tags closed.
43 - Various HTMLPurifier_Config convenience functions now accept another parameter
44 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
46 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
47 - Fix bug in ExtractStyleBlocks with comments in style tags
48 - Fix bug in comment parsing for DirectLex
49 - Flush output now displayed when in command line mode for unit tester
50 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
51 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
52 on the same element without emitting errors.
53 . Plugins now get their own changelogs according to project conventions.
54 . Convert tokens to use instanceof, reducing memory footprint and
55 improving comparison speed.
56 . Dry runs now supported in SimpleTest; testing facilities improved
57 . Bootstrap class added for handling autoloading functionality
58 . Implemented recursive glob at FSTools->globr

66 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
67 . New --php=php flag added, allows PHP executable to be specified (command
69 . htmlpurifier_add_test() preferred method to translate test files in to
70 classes, because it handles PHPT files too.
71 . Debugger class is deprecated and will be removed soon.
72 . Command line argument parsing for testing scripts revamped, now --opt value
74 . Smoketests now cleanup after magic quotes
75 . Generator now can output comments (however, comments are still stripped
76 from HTML Purifier output)
77 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
78 HTMLPurifier_VarParser->parse()
79 . Integers auto-cast into float type by VarParser.
80 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
81 during cache generation
82 . Reordered script calls in maintenance/flush.php
83 . Command line scripts now honor exit codes
84 . When --flush fails in unit testers, abort tests and print message
86 3.0.0, released 2008-01-06
87 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
88 until PHP 4 is completely deprecated, but no new features will be added
90 + Visibility declarations added
91 + Constructor methods renamed to __construct()
92 + PHP4 reference cruft removed (in progress)
93 ! CSS properties are now case-insensitive
94 ! DefinitionCacheFactory now can register new implementations

96 documents and cleaning their contents up. Requires the CSSTidy library
97 <http://csstidy.sourceforge.net/>. You can access the blocks with the
98 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
99 The output CSS can also be "scoped" for a specific element, use:
100 %Filter.ExtractStyleBlocksScope
101 ! Experimental support for some proprietary CSS attributes allowed:
102 opacity (and all of the browser-specific equivalents) and scrollbar colors.
103 Enable by setting %CSS.Proprietary to true.
104 - Colors missing # but in hex form will be corrected
105 - CSS Number algorithm improved
106 - Unit testing and multi-testing now on steroids: command lines,
107 XML output, and other goodies now added.

111 + HTMLPurifier_AttrDef_CSS_Filter
112 . Multitest now has a file docblock
114 2.1.3, released 2007-11-05
115 ! tests/multitest.php allows you to test multiple versions by running
116 tests/index.php through multiple interpreters using `phpv` shell
117 script (you must provide this script!)
118 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
120 - Injector algorithm further refined: off-by-one error regarding skip
121 counts for dormant injectors fixed
122 - Corrective blockquote definition now enabled for HTML 4.01 Strict
123 - Fatal error when <img> tag (or any other element with required attributes)
124 has 'id' attribute fixed, thanks NykO18 for reporting
125 - Fix warning emitted when a non-supported URI scheme is passed to the
126 MakeAbsolute URIFilter, thanks NykO18 (again)
127 - Further refine AutoParagraph injector. Behavior inside of elements
128 allowing paragraph tags clarified: only inline content delimeted by
129 double newlines (not block elements) are paragraphed.
130 - Buggy treatment of end tags of elements that have required attributes
131 fixed (does not manifest on default tag-set)
132 - Spurious internal content reorganization error suppressed
133 - HTMLDefinition->addElement now returns a reference to the created
134 element object, as implied by the documentation
135 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
136 - Fix a theoretical class of infinite loops from DirectLex reported
138 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
140 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
141 HTMLDefinition errors, this may indicate problems with error-collecting
143 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
144 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
145 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
146 to better communicate its purpose
147 . Error unit tests can now specify the expectation of no errors. Future
148 iterations of the harness will be extremely strict about what errors
150 . Extend Injector hooks to allow for more powerful injector routines
151 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
153 . Doxygen configuration file updated, with minor improvements
154 . Test runner now checks for similarly named files in conf/ directory too.
155 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
157 . Maintenance script for generating PH5P patch added, original PH5P source
158 file also added under version control

160 . Updated INSTALL file to state that 4.3.7 is the earliest version we
163 2.1.2, released 2007-09-03
164 ! Implemented Object module for trusted users
165 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
167 require_once 'HTMLPurifier/Lexer/PH5P.php';
168 $config->set('Core', 'LexerImpl', 'PH5P');
169 Note that this Lexer introduces some classes not in the HTMLPurifier
170 namespace. Also, this is PHP5 only.
171 ! CSS property border-spacing implemented
172 - Fix non-visible parsing error in DirectLex with empty tags that have
173 slashes inside attribute values.
174 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
175 accepted as valid CSS. Usually non-visible, because this styling is the
176 default for tables in most browsers. Thanks Brett Zamir for pointing
178 - Fix validation errors in configuration form
179 - Hammer out a bunch of edge-case bugs in the standalone distribution
180 - Inclusion reflection removed from URISchemeRegistry; you must manually
181 include any new schema files you wish to use
182 - Numerous typo fixes in documentation thanks to Brett Zamir
183 . Unit test refactoring for one logical test per test function
184 . Config and context parameters in ComplexHarness deprecated: instead, edit
185 the $config and $context member variables
186 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
187 really make a difference, but is good for completeness sake
188 . merge-library.php script refactored for greater code reusability and
191 2.1.1, released 2007-08-04
192 - Fix show-stopper bug in %URI.MakeAbsolute functionality
193 - Fix PHP4 syntax error in standalone version
194 . Add prefix directory to include path for standalone, this prevents
195 other installations from clobbering the standalone's URI schemes
196 . Single test methods can be invoked by prefixing with __only
198 2.1.0, released 2007-08-02
199 # flush-htmldefinition-cache.php superseded in favor of a generic
200 flush-definition-cache.php script, you can clear a specific cache
201 by passing its name as a parameter to the script
202 ! Phorum mod implemented for HTML Purifier
203 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
204 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
205 for PHP4 (DirectLex).
206 ! Standalone file now available, which greatly reduces the amount of
207 includes (although there are still a few files that reside in the
209 ! Relative URIs can now be transformed into their absolute equivalents
210 using %URI.Base and %URI.MakeAbsolute
211 ! Ruby implemented for XHTML 1.1

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

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

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

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