4 = KEY ====================
10 ==========================
12 4.6.0, unknown release date
13 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
14 Please update any verification scripts you may have.
15 # URI parsing algorithm was made more strict, so only prefixes which
16 looks like schemes will actually be schemes. Thanks
17 Michael Gusev <mgusev@sugarcrm.com> for fixing.
18 ! New directive %Core.AllowHostnameUnderscore which allows underscores
20 - Eliminate quadratic behavior in DOMLex by using a proper queue.
21 Thanks Ole Laursen for noticing this.
22 - Made Linkify URL parser a bit less permissive, so that non-breaking
23 spaces and commas are not included as part of URL. Thanks nAS for fixing.
24 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
25 David Hirtz for reporting.
27 4.5.0, released 2013-02-17
28 # Fix bug where stacked attribute transforms clobber each other;
29 this also means it's no longer possible to override attribute
30 transforms in later modules. No internal code was using this
31 but this may break some clients.
32 # We now use SHA-1 to identify cached definitions, instead of MD5.
33 ! Support display:inline-block
34 ! Support for more white-space CSS values.
35 ! Permit underscores in font families
36 ! Support for page-break-* CSS3 properties when proprietary properties
38 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
39 SGML excludes checking. If HTML Purifier is removing too much text
40 and you don't care about full standards compliance, try setting this to
42 - Use prepend for SPL autoloading on PHP 5.3 and later.
43 - Fix bug with nofollow transform when pre-existing rel exists.
44 - Fix bug where background:url() always gets lower-cased
45 (but not background-image:url())
46 - Fix bug with non lower-case color names in HTML
47 - Fix bug where data URI validation doesn't remove temporary files.
48 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
49 - Don't remove certain empty tags on RemoveEmpty.
51 4.4.0, released 2012-01-18
52 # Removed PEARSax3 handler.
53 # URI.Munge now munges URIs inside the same host that go from https
54 to http. Reported by Neike Taika-Tessaro.
55 # Core.EscapeNonASCIICharacters now always transforms entities to
56 entities, even if target encoding is UTF-8.
57 # Tighten up selector validation in ExtractStyleBlocks.
58 Non-syntactically valid selectors are now rejected, along with
59 some of the more obscure ones such as attribute selectors, the
60 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
61 ID and class selectors now work properly with the relevant
62 configuration attributes. Also, mute errors when parsing CSS
63 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
64 ! Added support for 'scope' attribute on tables.
65 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
66 ! Properly handle sub-lists directly nested inside of lists in
67 a standards compliant way, by moving them into the preceding <li>
68 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
69 limited allowed comments in untrusted situations.
70 ! Implement iframes, and allow them to be used in untrusted mode with
71 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
72 <brad.froehle@gmail.com> for submitting an initial version of the patch.
73 ! The Forms module now works properly for transitional doctypes.
74 ! Added support for internationalized domain names. You need the PEAR
75 Net_IDNA2 module to be in your path; if it is installed, ensure the
76 class can be loaded and then set %Core.EnableIDNA to true.
77 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
78 <yramirez-htmlpurifier@adicio.com> for reporting.
79 - Explicitly initialize anonModule variable to null.
80 - Do not duplicate nofollow if already present. Thanks 178
82 - Do not add nofollow if hostname matches our current host. Thanks 178
83 for reporting, and Neike Taika-Tessaro for helping diagnose.
84 - Do not unset parser variable; this fixes intermittent serialization
85 problems. Thanks Neike Taika-Tessaro for reporting, bill
86 <10010tiger@gmail.com> for diagnosing.
87 - Fix iconv truncation bug, where non-UTF-8 target encodings see
88 output truncated after around 8000 characters. Thanks Jörg Ludwig
89 <joerg.ludwig@iserv.eu> for reporting.
90 - Fix broken table content model for XHTML1.1 (and also earlier
91 versions, although the W3C validator doesn't catch those violations).
92 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
94 4.3.0, released 2011-03-27
95 # Fixed broken caching of customized raw definitions, but requires an
96 API change. The old API still works but will emit a warning,
97 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
98 for how to upgrade your code.
99 # Protect against Internet Explorer innerHTML behavior by specially
100 treating attributes with backticks but no angled brackets, quotes or
101 spaces. This constitutes a slight semantic change, which can be
102 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
104 # Protect against cssText/innerHTML by restricting allowed characters
105 used in fonts further than mandated by the specification and encoding
106 some extra special characters in URLs. Reported by Neike
107 Taika-Tessaro and Mario Heiderich.
108 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
109 ! More types of SPL autoloaders allowed on later versions of PHP.
110 ! Implementations for position, top, left, right, bottom, z-index
111 when %CSS.Trusted is on.
112 ! Add %Cache.SerializerPermissions option for custom serializer
113 directory/file permissions
114 ! Fix longstanding bug in Flash support for non-IE browsers, and
115 allow more wmode attributes.
116 ! Add %CSS.AllowedFonts to restrict permissible font names.
117 - Switch to an iterative traversal of the DOM, which prevents us
118 from running out of stack space for deeply nested documents.
119 Thanks Maxim Krizhanovsky for contributing a patch.
120 - Make removal of conditional IE comments ungreedy; thanks Bernd
122 - Escape CDATA before removing Internet Explorer comments.
123 - Fix removal of id attributes under certain conditions by ensuring
124 armor attributes are preserved when recreating tags.
125 - Check if schema.ser was corrupted.
126 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
127 This safety check is only done for HTMLPurifier.auto.php; if you
128 are using standalone or the specialized includes files, you're
129 expected to know what you're doing.
130 - Stop repeatedly writing the cache file after I'm done customizing a
131 raw definition. Reported by ajh.
132 - Switch to using require_once in the Bootstrap to work around bad
133 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
134 - Fix URI handling when hostname is missing but scheme is present.
135 Reported by Neike Taika-Tessaro.
136 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
138 - Fix harmless notice from indexing into empty string. Thanks Matthijs
139 Kooijman <matthijs@stdin.nl> for reporting.
140 - Don't autoclose no parent elements are able to support the element
141 that triggered the autoclose. In particular fixes strange behavior
142 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
143 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
145 4.2.0, released 2010-09-15
146 ! Added %Core.RemoveProcessingInstructions, which lets you remove
147 <? ... ?> statements.
148 ! Added %URI.DisableResources functionality; the directive originally
149 did nothing. Thanks David Rothstein for reporting.
150 ! Add documentation about configuration directive types.
151 ! Add %CSS.ForbiddenProperties configuration directive.
152 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
153 to utilize full-screen mode.
154 ! Add optional support for the <code>file</code> URI scheme, enable
155 by explicitly setting %URI.AllowedSchemes.
156 ! Add %Core.NormalizeNewlines options to allow turning off newline
158 - Fix improper handling of Internet Explorer conditional comments
159 by parser. Thanks zmonteca for reporting.
160 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
161 Thanks sidepodcast for the fix.
162 - Warn if an element is allowed, but an attribute it requires is
165 4.1.1, released 2010-05-31
166 - Fix undefined index warnings in maintenance scripts.
167 - Fix bug in DirectLex for parsing elements with a single attribute
169 - Rewrite CSS output logic for font-family and url(). Thanks Mario
170 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
171 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
172 - Emit an error for CollectErrors if a body is extracted
173 - Fix bug where in background-position for center keyword handling.
174 - Fix infinite loop when a wrapper element is inserted in a context
175 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
176 - Remove +x bit and shebang from index.php; only supported mode is to
177 explicitly call it with php.
178 - Make test script less chatty when log_errors is on.
180 4.1.0, released 2010-04-26
181 ! Support proprietary height attribute on table element
182 ! Support YouTube slideshows that contain /cp/ in their URL.
183 ! Support for data: URI scheme; not enabled by default, add it using
185 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
186 ! Support for Internet Explorer compatibility with %HTML.SafeObject
187 using %Output.FlashCompat.
188 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
189 - Always quote the insides of url(...) in CSS.
191 4.0.0, released 2009-07-07
192 # APIs for ConfigSchema subsystem have substantially changed. See
193 docs/dev-config-bcbreaks.txt for details; in essence, anything that
194 had both namespace and directive now have a single unified key.
195 # Some configuration directives were renamed, specifically:
196 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
197 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
198 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
199 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
200 As usual, the old directive names will still work, but will throw E_NOTICE
202 # The allowed values for class have been relaxed to allow all of CDATA for
203 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
204 %Attr.ClassUseCDATA to false.
205 # Instead of appending the content model to an old content model, a blank
206 element will replace the old content model. You can use #SUPER to get
207 the old content model.
208 ! More robust support for name="" and id=""
209 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
210 configuration, and have changes to that configuration be propagated
211 to all of its children.
212 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
213 the name attribute when set. Use with care. Thanks Ian Cook for
215 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
216 tags that contain non-breaking spaces as well other whitespace. You
217 can also modify which tags should have maintained with
218 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
219 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
220 classes users can use to a specified finite set of classes, and
221 %Attr.ForbiddenClasses, which is the logical inverse.
222 ! You can now maintain your own configuration schema directories by
223 creating a config-schema.php file or passing an extra argument. Check
224 docs/dev-config-schema.html for more details.
225 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
226 your configuration in a compact serial file, which you can unserialize
227 and use directly without having to go through the overhead of setup.
228 - Fix bug where URIDefinition would not get cleared if it's directives got
230 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
231 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
232 - Make %URI.Munge not apply to links that have the same host as your host.
233 - Prevent stray </body> tag from truncating output, if a second </body>
235 . Created script maintenance/rename-config.php for renaming a configuration
236 directive while maintaining its alias. This script does not change source code.
237 . Implement namespace locking for definition construction, to prevent
238 bugs where a directive is used for definition construction but is not
239 used to construct the cache hash.
241 3.3.0, released 2009-02-16
242 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
243 ! Implement generic property list classess
244 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
245 does not do the "right thing" with characters not supported in the output
247 - Spellcheck UTF-8: The Secret To Character Encoding
248 - Fix improper removal of the contents of elements with only whitespace. Thanks
249 Eric Wald for reporting.
250 - Fix broken test suite in versions of PHP without spl_autoload_register()
251 - Fix degenerate case with YouTube filter involving double hyphens.
252 Thanks Pierre Attar for reporting.
253 - Fix YouTube rendering problem on certain versions of Firefox.
254 - Fix CSSDefinition Printer problems with decorators
255 - Add text parameter to unit tests, forces text output
256 . Add verbose mode to command line test runner, use (--verbose)
257 . Turn on unit tests for UnitConverter
258 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
259 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
261 . Removed trailing whitespace from all text files, see
262 remote-trailing-whitespace.php maintenance script.
263 . Convert configuration to use property list backend.
265 3.2.0, released 2008-10-31
266 # Using %Core.CollectErrors forces line number/column tracking on, whereas
267 previously you could theoretically turn it off.
268 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
269 use handleEnd() instead.
270 ! %Output.AttrSort for when you need your attributes in alphabetical order to
271 deal with a bug in FCKEditor. Requested by frank farmer.
272 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
273 ! Proper support for name attribute. It is now allowed and equivalent to the id
274 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
275 is heavy (for all doctypes).
276 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
277 use on hand-written HTML.
278 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
279 the strategy to be used, standalone, on untrusted input.
280 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
281 processing of left angled brackets in smileys and other whatnot.
282 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
283 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
284 the --only-phpt parameter, although for backwards-compatibility the flag
286 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
287 Users who are not performing inbound filtering, this may seem a little
288 useless, but as a bonus, the test suite and handling of edge cases is also
290 ! Experimental implementation of forms for %HTML.Trusted
291 ! Track column numbers when maintain line numbers is on
292 ! Proprietary 'background' attribute on table-related elements converted into
293 corresponding CSS. Thanks Fusemail for sponsoring this feature!
294 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
296 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
297 time of operation varies slightly from notifyEnd() as *all* end tokens are
298 processed by the injector before they are subject to the well-formedness rules.
299 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
300 basename of image when not present.
301 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
302 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
303 the other involving an undefined $is_folder error.
304 - Throw error when %Core.Encoding is set to a spurious value. Previously,
305 this errored silently and returned false.
306 - Redirected stderr to stdout for flush error output.
307 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
309 - Do not re-munge URL if the output URL has the same host as the input URL.
311 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
312 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
313 - Fix bug with inline elements in blockquotes conflicting with strict doctype
314 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
315 - Fix bug where dots and double-dots in absolute URLs without hostname were
316 not collapsed by URIFilter_MakeAbsolute.
317 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
318 by reordering their addition.
319 - Will now throw exception on many error conditions during lexer creation; also
320 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
322 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
323 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
324 Reported by David Morton.
325 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
326 for more interesting filter-backtracking
327 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
328 index to reprocess tokens.
329 . StringHashParser now allows for multiline sections with "empty" content;
330 previously the section would remain undefined.
331 . Added --quick option to multitest.php, which tests only the most recent
332 release for each series.
333 . Added --distro option to multitest.php, which accepts either 'normal' or
334 'standalone'. This supercedes --exclude-normal and --exclude-standalone
336 3.1.1, released 2008-06-19
337 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
338 In order to enable this again, please set %URI.MungeResources to true.
339 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
340 and height/width HTML with %HTML.MaxImgLength.
341 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
342 for sponsoring this feature. Check out the corresponding documentation
343 for details. (Att Nightly testers: The API for this feature changed before
344 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
345 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
346 ! Implemented post URI filtering. Set member variable $post to true to set
348 ! Allow modules to define injectors via $info_injector. Injectors are
349 automatically disabled if injector's needed elements are not found.
350 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
351 Thanks Chris for sponsoring. If you've been using ad hoc code from the
352 forums, PLEASE use this instead.
353 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
354 embedded, tag name, attribute name, CSS property name). See %URI.Munge
355 for more details. Requested by Jochem Blok.
356 - Disable percent height/width attributes for img.
357 - AttrValidator operations are now atomic; updates to attributes are not
358 manifest in token until end of operations. This prevents naughty internal
359 code from directly modifying CurrentToken when they're not supposed to.
360 This semantics change was requested by frank farmer.
361 - Percent encoding checks enabled for URI query and fragment
362 - Fix stray backslashes in font-family; CSS Unicode character escapes are
363 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
365 - Improve parseCDATA algorithm to take into account newline normalization
366 - Account for browser confusion between Yen character and backslash in
367 Shift_JIS encoding. This fix generalizes to any other encoding which is not
368 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
369 - Fix missing configuration parameter in Generator calls. Thanks vs for the
371 - Improved adherence to Unicode by checking for non-character codepoints.
372 Thanks Geoffrey Sneddon for reporting. This may result in degraded
373 performance for extremely large inputs.
374 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
376 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
377 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
379 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
380 to __construct($min, $max). __construct(true) is equivalent to
382 . Added HTMLPurifier_AttrDef_Switch class
383 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
384 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
385 get this called with the configuration object. All modules now
386 use this rather than __construct(), although legacy code using constructors
387 will still work--the new format, however, lets modules access the
388 configuration object for HTML namespace dependant tweaks.
389 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
390 . ConfigSchema data-structure heavily optimized; on average it uses a third
391 the memory it did previously. The interface has changed accordingly,
392 consult changes to HTMLPurifier_Config for details.
393 . Variable parsing types now are magic integers instead of strings
394 . Added benchmark for ConfigSchema
395 . HTMLPurifier_Generator requires $config and $context parameters. If you
396 don't know what they should be, use HTMLPurifier_Config::createDefault()
397 and new HTMLPurifier_Context().
398 . Printers now properly distinguish between output configuration, and
399 target configuration. This is not applicable to scripts using
400 the Printers for HTML Purifier related tasks.
401 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
402 fatal errors will ensue.
403 . URIFilter->prepare can return false in order to abort loading of the filter
404 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
405 an external resource.
406 . %URI.Munge functionality factored out into a post-filter class.
407 . Added CurrentCSSProperty context variable during CSS validation
409 3.1.0, released 2008-05-18
410 # Unnecessary references to objects (vestiges of PHP4) removed from method
411 signatures. The following methods do not need references when assigning from
412 them and will result in E_STRICT errors if you try:
413 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
414 + HTMLPurifier_ConfigSchema::instance()
415 + HTMLPurifier_DefinitionCacheFactory::instance()
416 + HTMLPurifier_DefinitionCacheFactory->create()
417 + HTMLPurifier_DoctypeRegistry->register()
418 + HTMLPurifier_DoctypeRegistry->get()
419 + HTMLPurifier_HTMLModule->addElement()
420 + HTMLPurifier_HTMLModule->addBlankElement()
421 + HTMLPurifier_LanguageFactory::instance()
422 # Printer_ConfigForm's get*() functions were static-ified
423 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
424 form of tag@attr, NOT tag.attr (which will throw an error and won't do
425 anything). This is for forwards compatibility with XML; you'd do best
426 to migrate an %HTML.AllowedAttributes directives to this syntax too.
427 ! Allow index to be false for config from form creation
428 ! Added HTMLPurifier::VERSION constant
429 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
430 and allows for version numbers like "3.1.0-dev".
431 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
432 ! HTML Purifier's URI handling is a lot more robust, with much stricter
433 validation checks and better percent encoding handling. Thanks Gareth Heyes
434 for indicating security vulnerabilities from lax percent encoding.
435 ! Bootstrap autoloader deals more robustly with classes that don't exist,
436 preventing class_exists($class, true) from barfing.
437 - InterchangeBuilder now alphabetizes its lists
438 - Validation error in configdoc output fixed
439 - Iconv and other encoding errors muted even with custom error handlers that
440 do not honor error_reporting
441 - Add protection against imagecrash attack with CSS height/width
442 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
443 - Fixed and revamped broken ConfigForm smoketest
444 - Bug with bool/null fields in Printer_ConfigForm fixed
445 - Bug with global forbidden attributes fixed
446 - Improved error messages for allowed and forbidden HTML elements and attributes
447 - Missing (or null) in configdoc documentation restored
448 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
449 of DOM), HTML Purifier punts to DirectLex
450 - Fatal error with unserialization of ScriptRequired
451 - Created directories are now chmod'ed properly
452 - Fixed bug with fallback languages in LanguageFactory
453 - Standalone testing setup properly with autoload
454 . Out-of-date documentation revised
455 . UTF-8 encoding check optimization as suggested by Diego
456 . HTMLPurifier_Error removed in favor of exceptions
457 . More copy() function removed; should use clone instead
458 . More extensive unit tests for HTMLDefinition
459 . assertPurification moved to central harness
460 . HTMLPurifier_Generator accepts $config and $context parameters during
461 instantiation, not runtime
462 . Double-quotes outside of attribute values are now unescaped
464 3.1.0rc1, released 2008-04-22
465 # Autoload support added. Internal require_once's removed in favor of an
466 explicit require list or autoloading. To use HTML Purifier,
467 you must now either use HTMLPurifier.auto.php
468 or HTMLPurifier.includes.php; setting the include path and including
469 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
470 as well to register our autoload handler (or modify your autoload function
471 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
472 HTMLPurifier.safe-includes.php for a less performance friendly but more
