1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.9.0, unknown release date
13 ! %URI.DefaultScheme can now be set to null, in which case
14 all relative paths are removed.
15 ! New CSS properties: min-width, max-width, min-height, max-height (#94)
16 - When idn_to_ascii is defined, we might accept malformed
17 hostnames. Apply validation to the result in such cases.
18 - Close directory when done in Serializer DefinitionCache (#100)
19 - Deleted some asserts to avoid linters from choking (#97)
20 - Rework Serializer cache behavior to avoid chmod'ing if possible (#32)
21 - Embedded semicolons in strings in CSS are now handled correctly!
22 - We accidentally dropped certain Unicode characters if there was
23 one or more invalid characters. This has been fixed, thanks
24 to mpyw <ryosuke_i_628@yahoo.co.jp>
25 - Fix for "Don't truncate upon encountering </div> when using DOMLex"
26 caused a regression with HTML 4.01 Strict parsing with libxml 2.9.1
27 (and maybe later versions, but known OK with libxml 2.9.4). The
28 fix is to go about handling truncation a bit more cleverly so that
29 we can wrap with divs (sidestepping the bug) but slurping out the
30 rest of the text in case it ran off the end. (#78)
31 # By default, when a link has a target attribute associated
32 with it, we now also add rel="noopener" in order to
33 prevent the new window from being able to overwrite
34 the original frame. To disable this protection,
35 set %HTML.TargetNoopener to FALSE.
37 4.8.0, released 2016-07-16
38 # By default, when a link has a target attribute associated
39 with it, we now also add rel="noreferrer" in order to
40 prevent the new window from being able to overwrite
41 the original frame. To disable this protection,
42 set %HTML.TargetNoreferrer to FALSE.
43 ! Full PHP 7 compatibility, the test suite is ALL GO.
44 ! %CSS.AllowDuplicates permits duplicate CSS properties.
45 ! Support for 'tel' URIs.
46 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
47 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
49 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
50 - alt truncation could result in malformed UTF-8 sequence. Don't
51 truncate. Thanks Brandon Farber for reporting.
52 - Linkify regex is smarter, based off of Gruber's regex.
53 - IDNA supported natively on PHP 5.3 and later.
54 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
56 - Minor bounds error fix to squash a PHP 7 notice.
57 - Support non-/tmp temporary directories for data:// validation
58 - Give a better error message when a user attempts to allow
59 ul/ol without allowing li.
60 - On some versions of PHP, the Serializer DefinitionCache could
61 infinite loop when the directory exists but is not listable. (#49)
62 - Don't match for <body> inside comments with
63 %Core.ConvertDocumentToFragment. (#67)
64 - SafeObject is now less case sensitive. (#57)
65 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
68 4.7.0, released 2015-08-04
69 # opacity is now considered a "tricky" CSS property rather than a
71 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
72 an element should be considered "empty" (maybe preserve if it
73 has attributes), and modify iframe support so that the iframe
74 is removed if it is missing a src attribute. Thanks meeva for
76 - Don't truncate upon encountering </div> when using DOMLex. Thanks
77 Myrto Christina for finally convincing me to fix this.
78 - Update YouTube filter for new code.
79 - Fix parsing of rgb() values with spaces in them for 'border'
81 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
84 4.6.0, released 2013-11-30
85 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
86 Please update any verification scripts you may have.
87 # URI parsing algorithm was made more strict, so only prefixes which
88 looks like schemes will actually be schemes. Thanks
89 Michael Gusev <mgusev@sugarcrm.com> for fixing.
90 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
92 ! New directive %Core.AllowHostnameUnderscore which allows underscores
94 - Eliminate quadratic behavior in DOMLex by using a proper queue.
95 Thanks Ole Laursen for noticing this.
96 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
97 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
98 Networks for sponsoring this work.
99 - Made Linkify URL parser a bit less permissive, so that non-breaking
100 spaces and commas are not included as part of URL. Thanks nAS for fixing.
101 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
102 David Hirtz for reporting.
103 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
106 4.5.0, released 2013-02-17
107 # Fix bug where stacked attribute transforms clobber each other;
108 this also means it's no longer possible to override attribute
109 transforms in later modules. No internal code was using this
110 but this may break some clients.
111 # We now use SHA-1 to identify cached definitions, instead of MD5.
112 ! Support display:inline-block
113 ! Support for more white-space CSS values.
114 ! Permit underscores in font families
115 ! Support for page-break-* CSS3 properties when proprietary properties
117 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
118 SGML excludes checking. If HTML Purifier is removing too much text
119 and you don't care about full standards compliance, try setting this to
121 - Use prepend for SPL autoloading on PHP 5.3 and later.
122 - Fix bug with nofollow transform when pre-existing rel exists.
123 - Fix bug where background:url() always gets lower-cased
124 (but not background-image:url())
125 - Fix bug with non lower-case color names in HTML
126 - Fix bug where data URI validation doesn't remove temporary files.
127 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
128 - Don't remove certain empty tags on RemoveEmpty.
130 4.4.0, released 2012-01-18
131 # Removed PEARSax3 handler.
132 # URI.Munge now munges URIs inside the same host that go from https
133 to http. Reported by Neike Taika-Tessaro.
134 # Core.EscapeNonASCIICharacters now always transforms entities to
135 entities, even if target encoding is UTF-8.
136 # Tighten up selector validation in ExtractStyleBlocks.
137 Non-syntactically valid selectors are now rejected, along with
138 some of the more obscure ones such as attribute selectors, the
139 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
140 ID and class selectors now work properly with the relevant
141 configuration attributes. Also, mute errors when parsing CSS
142 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
143 ! Added support for 'scope' attribute on tables.
144 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
145 ! Properly handle sub-lists directly nested inside of lists in
146 a standards compliant way, by moving them into the preceding <li>
147 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
148 limited allowed comments in untrusted situations.
149 ! Implement iframes, and allow them to be used in untrusted mode with
150 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
151 <brad.froehle@gmail.com> for submitting an initial version of the patch.
152 ! The Forms module now works properly for transitional doctypes.
153 ! Added support for internationalized domain names. You need the PEAR
154 Net_IDNA2 module to be in your path; if it is installed, ensure the
155 class can be loaded and then set %Core.EnableIDNA to true.
156 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
157 <yramirez-htmlpurifier@adicio.com> for reporting.
158 - Explicitly initialize anonModule variable to null.
159 - Do not duplicate nofollow if already present. Thanks 178
161 - Do not add nofollow if hostname matches our current host. Thanks 178
162 for reporting, and Neike Taika-Tessaro for helping diagnose.
163 - Do not unset parser variable; this fixes intermittent serialization
164 problems. Thanks Neike Taika-Tessaro for reporting, bill
165 <10010tiger@gmail.com> for diagnosing.
166 - Fix iconv truncation bug, where non-UTF-8 target encodings see
167 output truncated after around 8000 characters. Thanks Jörg Ludwig
168 <joerg.ludwig@iserv.eu> for reporting.
169 - Fix broken table content model for XHTML1.1 (and also earlier
170 versions, although the W3C validator doesn't catch those violations).
171 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
173 4.3.0, released 2011-03-27
174 # Fixed broken caching of customized raw definitions, but requires an
175 API change. The old API still works but will emit a warning,
176 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
177 for how to upgrade your code.
178 # Protect against Internet Explorer innerHTML behavior by specially
179 treating attributes with backticks but no angled brackets, quotes or
180 spaces. This constitutes a slight semantic change, which can be
181 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
183 # Protect against cssText/innerHTML by restricting allowed characters
184 used in fonts further than mandated by the specification and encoding
185 some extra special characters in URLs. Reported by Neike
186 Taika-Tessaro and Mario Heiderich.
187 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
188 ! More types of SPL autoloaders allowed on later versions of PHP.
189 ! Implementations for position, top, left, right, bottom, z-index
190 when %CSS.Trusted is on.
191 ! Add %Cache.SerializerPermissions option for custom serializer
192 directory/file permissions
193 ! Fix longstanding bug in Flash support for non-IE browsers, and
194 allow more wmode attributes.
195 ! Add %CSS.AllowedFonts to restrict permissible font names.
196 - Switch to an iterative traversal of the DOM, which prevents us
197 from running out of stack space for deeply nested documents.
198 Thanks Maxim Krizhanovsky for contributing a patch.
199 - Make removal of conditional IE comments ungreedy; thanks Bernd
201 - Escape CDATA before removing Internet Explorer comments.
202 - Fix removal of id attributes under certain conditions by ensuring
203 armor attributes are preserved when recreating tags.
204 - Check if schema.ser was corrupted.
205 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
206 This safety check is only done for HTMLPurifier.auto.php; if you
207 are using standalone or the specialized includes files, you're
208 expected to know what you're doing.
209 - Stop repeatedly writing the cache file after I'm done customizing a
210 raw definition. Reported by ajh.
211 - Switch to using require_once in the Bootstrap to work around bad
212 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
213 - Fix URI handling when hostname is missing but scheme is present.
214 Reported by Neike Taika-Tessaro.
215 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
217 - Fix harmless notice from indexing into empty string. Thanks Matthijs
218 Kooijman <matthijs@stdin.nl> for reporting.
219 - Don't autoclose no parent elements are able to support the element
220 that triggered the autoclose. In particular fixes strange behavior
221 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
222 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
224 4.2.0, released 2010-09-15
225 ! Added %Core.RemoveProcessingInstructions, which lets you remove
226 <? ... ?> statements.
227 ! Added %URI.DisableResources functionality; the directive originally
228 did nothing. Thanks David Rothstein for reporting.
229 ! Add documentation about configuration directive types.
230 ! Add %CSS.ForbiddenProperties configuration directive.
231 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
232 to utilize full-screen mode.
233 ! Add optional support for the <code>file</code> URI scheme, enable
234 by explicitly setting %URI.AllowedSchemes.
235 ! Add %Core.NormalizeNewlines options to allow turning off newline
237 - Fix improper handling of Internet Explorer conditional comments
238 by parser. Thanks zmonteca for reporting.
239 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
240 Thanks sidepodcast for the fix.
241 - Warn if an element is allowed, but an attribute it requires is
244 4.1.1, released 2010-05-31
245 - Fix undefined index warnings in maintenance scripts.
246 - Fix bug in DirectLex for parsing elements with a single attribute
248 - Rewrite CSS output logic for font-family and url(). Thanks Mario
249 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
250 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
251 - Emit an error for CollectErrors if a body is extracted
252 - Fix bug where in background-position for center keyword handling.
253 - Fix infinite loop when a wrapper element is inserted in a context
254 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
255 - Remove +x bit and shebang from index.php; only supported mode is to
256 explicitly call it with php.
257 - Make test script less chatty when log_errors is on.
259 4.1.0, released 2010-04-26
260 ! Support proprietary height attribute on table element
261 ! Support YouTube slideshows that contain /cp/ in their URL.
262 ! Support for data: URI scheme; not enabled by default, add it using
264 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
265 ! Support for Internet Explorer compatibility with %HTML.SafeObject
266 using %Output.FlashCompat.
267 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
268 - Always quote the insides of url(...) in CSS.
270 4.0.0, released 2009-07-07
271 # APIs for ConfigSchema subsystem have substantially changed. See
272 docs/dev-config-bcbreaks.txt for details; in essence, anything that
273 had both namespace and directive now have a single unified key.
274 # Some configuration directives were renamed, specifically:
275 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
276 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
277 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
278 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
279 As usual, the old directive names will still work, but will throw E_NOTICE
281 # The allowed values for class have been relaxed to allow all of CDATA for
282 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
283 %Attr.ClassUseCDATA to false.
284 # Instead of appending the content model to an old content model, a blank
285 element will replace the old content model. You can use #SUPER to get
286 the old content model.
287 ! More robust support for name="" and id=""
288 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
289 configuration, and have changes to that configuration be propagated
290 to all of its children.
291 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
292 the name attribute when set. Use with care. Thanks Ian Cook for
294 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
295 tags that contain non-breaking spaces as well other whitespace. You
296 can also modify which tags should have maintained with
297 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
298 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
299 classes users can use to a specified finite set of classes, and
300 %Attr.ForbiddenClasses, which is the logical inverse.
301 ! You can now maintain your own configuration schema directories by
302 creating a config-schema.php file or passing an extra argument. Check
303 docs/dev-config-schema.html for more details.
304 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
305 your configuration in a compact serial file, which you can unserialize
306 and use directly without having to go through the overhead of setup.
307 - Fix bug where URIDefinition would not get cleared if it's directives got
309 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
310 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
311 - Make %URI.Munge not apply to links that have the same host as your host.
312 - Prevent stray </body> tag from truncating output, if a second </body>
314 . Created script maintenance/rename-config.php for renaming a configuration
315 directive while maintaining its alias. This script does not change source code.
316 . Implement namespace locking for definition construction, to prevent
317 bugs where a directive is used for definition construction but is not
318 used to construct the cache hash.
320 3.3.0, released 2009-02-16
321 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
322 ! Implement generic property list classess
323 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
324 does not do the "right thing" with characters not supported in the output
326 - Spellcheck UTF-8: The Secret To Character Encoding
327 - Fix improper removal of the contents of elements with only whitespace. Thanks
328 Eric Wald for reporting.
329 - Fix broken test suite in versions of PHP without spl_autoload_register()
330 - Fix degenerate case with YouTube filter involving double hyphens.
331 Thanks Pierre Attar for reporting.
332 - Fix YouTube rendering problem on certain versions of Firefox.
333 - Fix CSSDefinition Printer problems with decorators
334 - Add text parameter to unit tests, forces text output
335 . Add verbose mode to command line test runner, use (--verbose)
336 . Turn on unit tests for UnitConverter
337 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
338 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
340 . Removed trailing whitespace from all text files, see
341 remote-trailing-whitespace.php maintenance script.
342 . Convert configuration to use property list backend.
344 3.2.0, released 2008-10-31
345 # Using %Core.CollectErrors forces line number/column tracking on, whereas
346 previously you could theoretically turn it off.
347 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
348 use handleEnd() instead.
349 ! %Output.AttrSort for when you need your attributes in alphabetical order to
350 deal with a bug in FCKEditor. Requested by frank farmer.
351 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
352 ! Proper support for name attribute. It is now allowed and equivalent to the id
353 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
354 is heavy (for all doctypes).
355 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
356 use on hand-written HTML.
357 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
358 the strategy to be used, standalone, on untrusted input.
359 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
360 processing of left angled brackets in smileys and other whatnot.
361 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
362 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
363 the --only-phpt parameter, although for backwards-compatibility the flag
365 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
366 Users who are not performing inbound filtering, this may seem a little
367 useless, but as a bonus, the test suite and handling of edge cases is also
369 ! Experimental implementation of forms for %HTML.Trusted
370 ! Track column numbers when maintain line numbers is on
371 ! Proprietary 'background' attribute on table-related elements converted into
372 corresponding CSS. Thanks Fusemail for sponsoring this feature!
373 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
375 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
376 time of operation varies slightly from notifyEnd() as *all* end tokens are
377 processed by the injector before they are subject to the well-formedness rules.
378 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
379 basename of image when not present.
380 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
381 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
382 the other involving an undefined $is_folder error.
383 - Throw error when %Core.Encoding is set to a spurious value. Previously,
384 this errored silently and returned false.
385 - Redirected stderr to stdout for flush error output.
386 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
388 - Do not re-munge URL if the output URL has the same host as the input URL.
390 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
391 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
392 - Fix bug with inline elements in blockquotes conflicting with strict doctype
393 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
394 - Fix bug where dots and double-dots in absolute URLs without hostname were
395 not collapsed by URIFilter_MakeAbsolute.
396 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
397 by reordering their addition.
398 - Will now throw exception on many error conditions during lexer creation; also
399 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
401 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
402 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
403 Reported by David Morton.
404 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
405 for more interesting filter-backtracking
406 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
407 index to reprocess tokens.
408 . StringHashParser now allows for multiline sections with "empty" content;
409 previously the section would remain undefined.
410 . Added --quick option to multitest.php, which tests only the most recent
411 release for each series.
412 . Added --distro option to multitest.php, which accepts either 'normal' or
413 'standalone'. This supercedes --exclude-normal and --exclude-standalone
415 3.1.1, released 2008-06-19
416 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
417 In order to enable this again, please set %URI.MungeResources to true.
418 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
419 and height/width HTML with %HTML.MaxImgLength.
420 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
421 for sponsoring this feature. Check out the corresponding documentation
422 for details. (Att Nightly testers: The API for this feature changed before
423 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
424 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
425 ! Implemented post URI filtering. Set member variable $post to true to set
427 ! Allow modules to define injectors via $info_injector. Injectors are
428 automatically disabled if injector's needed elements are not found.
429 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
430 Thanks Chris for sponsoring. If you've been using ad hoc code from the
431 forums, PLEASE use this instead.
432 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
433 embedded, tag name, attribute name, CSS property name). See %URI.Munge
434 for more details. Requested by Jochem Blok.
435 - Disable percent height/width attributes for img.
436 - AttrValidator operations are now atomic; updates to attributes are not
437 manifest in token until end of operations. This prevents naughty internal
438 code from directly modifying CurrentToken when they're not supposed to.
439 This semantics change was requested by frank farmer.
440 - Percent encoding checks enabled for URI query and fragment
441 - Fix stray backslashes in font-family; CSS Unicode character escapes are
442 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
444 - Improve parseCDATA algorithm to take into account newline normalization
445 - Account for browser confusion between Yen character and backslash in
446 Shift_JIS encoding. This fix generalizes to any other encoding which is not
447 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
448 - Fix missing configuration parameter in Generator calls. Thanks vs for the
450 - Improved adherence to Unicode by checking for non-character codepoints.
451 Thanks Geoffrey Sneddon for reporting. This may result in degraded
452 performance for extremely large inputs.
453 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
455 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
456 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
458 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
459 to __construct($min, $max). __construct(true) is equivalent to
461 . Added HTMLPurifier_AttrDef_Switch class
462 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
463 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
464 get this called with the configuration object. All modules now
465 use this rather than __construct(), although legacy code using constructors
466 will still work--the new format, however, lets modules access the
467 configuration object for HTML namespace dependant tweaks.
468 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
469 . ConfigSchema data-structure heavily optimized; on average it uses a third
470 the memory it did previously. The interface has changed accordingly,
471 consult changes to HTMLPurifier_Config for details.
472 . Variable parsing types now are magic integers instead of strings
473 . Added benchmark for ConfigSchema
474 . HTMLPurifier_Generator requires $config and $context parameters. If you
475 don't know what they should be, use HTMLPurifier_Config::createDefault()
476 and new HTMLPurifier_Context().
477 . Printers now properly distinguish between output configuration, and
478 target configuration. This is not applicable to scripts using
479 the Printers for HTML Purifier related tasks.
480 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
481 fatal errors will ensue.
482 . URIFilter->prepare can return false in order to abort loading of the filter
483 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
484 an external resource.
485 . %URI.Munge functionality factored out into a post-filter class.
486 . Added CurrentCSSProperty context variable during CSS validation
488 3.1.0, released 2008-05-18
489 # Unnecessary references to objects (vestiges of PHP4) removed from method
490 signatures. The following methods do not need references when assigning from
491 them and will result in E_STRICT errors if you try:
492 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
493 + HTMLPurifier_ConfigSchema::instance()
494 + HTMLPurifier_DefinitionCacheFactory::instance()
495 + HTMLPurifier_DefinitionCacheFactory->create()
496 + HTMLPurifier_DoctypeRegistry->register()
497 + HTMLPurifier_DoctypeRegistry->get()
498 + HTMLPurifier_HTMLModule->addElement()
499 + HTMLPurifier_HTMLModule->addBlankElement()
500 + HTMLPurifier_LanguageFactory::instance()
501 # Printer_ConfigForm's get*() functions were static-ified
502 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
503 form of tag@attr, NOT tag.attr (which will throw an error and won't do
504 anything). This is for forwards compatibility with XML; you'd do best
505 to migrate an %HTML.AllowedAttributes directives to this syntax too.
506 ! Allow index to be false for config from form creation
507 ! Added HTMLPurifier::VERSION constant
508 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
509 and allows for version numbers like "3.1.0-dev".
510 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
511 ! HTML Purifier's URI handling is a lot more robust, with much stricter
512 validation checks and better percent encoding handling. Thanks Gareth Heyes
513 for indicating security vulnerabilities from lax percent encoding.
514 ! Bootstrap autoloader deals more robustly with classes that don't exist,
515 preventing class_exists($class, true) from barfing.
516 - InterchangeBuilder now alphabetizes its lists
517 - Validation error in configdoc output fixed
518 - Iconv and other encoding errors muted even with custom error handlers that

522 - Fixed and revamped broken ConfigForm smoketest
523 - Bug with bool/null fields in Printer_ConfigForm fixed
524 - Bug with global forbidden attributes fixed
525 - Improved error messages for allowed and forbidden HTML elements and attributes
526 - Missing (or null) in configdoc documentation restored
527 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
528 of DOM), HTML Purifier punts to DirectLex
529 - Fatal error with unserialization of ScriptRequired
530 - Created directories are now chmod'ed properly
531 - Fixed bug with fallback languages in LanguageFactory
532 - Standalone testing setup properly with autoload

534 . UTF-8 encoding check optimization as suggested by Diego
535 . HTMLPurifier_Error removed in favor of exceptions
536 . More copy() function removed; should use clone instead
537 . More extensive unit tests for HTMLDefinition
538 . assertPurification moved to central harness
539 . HTMLPurifier_Generator accepts $config and $context parameters during
540 instantiation, not runtime
541 . Double-quotes outside of attribute values are now unescaped
543 3.1.0rc1, released 2008-04-22
544 # Autoload support added. Internal require_once's removed in favor of an
545 explicit require list or autoloading. To use HTML Purifier,
546 you must now either use HTMLPurifier.auto.php
547 or HTMLPurifier.includes.php; setting the include path and including
548 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
549 as well to register our autoload handler (or modify your autoload function
550 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
551 HTMLPurifier.safe-includes.php for a less performance friendly but more
552 user-friendly library load.
553 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
554 information is stored in the ConfigSchema directory, and the
555 maintenance/generate-schema-cache.php generates the schema.ser file, which
556 is now instantiated. Support for userland schema changes coming soon!
557 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
558 alias; to get rid of these errors just modify your configuration to use
559 the new directive name.
560 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
561 enabled using %Filter.$filter_name or by setting your own filters using
563 # Directive-level safety properties superceded in favor of module-level
564 safety. Internal method HTMLModule->addElement() has changed, although
565 the externally visible HTMLDefinition->addElement has *not* changed.
566 ! Extra utility classes for testing and non-library operations can
567 be found in extras/. Specifically, these are FSTools and ConfigDoc.
568 You may find a use for these in your own project, but right now they
569 are highly experimental and volatile.
570 ! Integration with PHPT allows for automated smoketests
571 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
572 by Chris. You can enable them with %HTML.Proprietary if your client
574 ! Support for !important CSS cascade modifier. By default, this will be stripped
575 from CSS, but you can enable it using %CSS.AllowImportant
576 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
578 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
579 Developer error (not enduser error) can cause these to be triggered.
580 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
581 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
582 mucking around with HTMLPurifier_CSSDefinition
583 ! ConfigDoc output has been enhanced with version and deprecation info.
584 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
585 - Autoclose now operates iteratively, i.e. <span><span><div> now has
586 both span tags closed.
587 - Various HTMLPurifier_Config convenience functions now accept another parameter
588 $schema which defines what HTMLPurifier_ConfigSchema to use besides the

617 . Command line argument parsing for testing scripts revamped, now --opt value
619 . Smoketests now cleanup after magic quotes
620 . Generator now can output comments (however, comments are still stripped
621 from HTML Purifier output)

626 during cache generation
627 . Reordered script calls in maintenance/flush.php
628 . Command line scripts now honor exit codes
629 . When --flush fails in unit testers, abort tests and print message

645 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
646 The output CSS can also be "scoped" for a specific element, use:
647 %Filter.ExtractStyleBlocksScope
648 ! Experimental support for some proprietary CSS attributes allowed:
649 opacity (and all of the browser-specific equivalents) and scrollbar colors.
650 Enable by setting %CSS.Proprietary to true.

659 . Multitest now has a file docblock
661 2.1.3, released 2007-11-05
662 ! tests/multitest.php allows you to test multiple versions by running
663 tests/index.php through multiple interpreters using `phpv` shell
664 script (you must provide this script!)
665 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
667 - Injector algorithm further refined: off-by-one error regarding skip
668 counts for dormant injectors fixed
669 - Corrective blockquote definition now enabled for HTML 4.01 Strict
670 - Fatal error when <img> tag (or any other element with required attributes)

677 - Buggy treatment of end tags of elements that have required attributes
678 fixed (does not manifest on default tag-set)
679 - Spurious internal content reorganization error suppressed

691 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
692 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
693 to better communicate its purpose
694 . Error unit tests can now specify the expectation of no errors. Future
695 iterations of the harness will be extremely strict about what errors
697 . Extend Injector hooks to allow for more powerful injector routines
698 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
700 . Doxygen configuration file updated, with minor improvements

714 require_once 'HTMLPurifier/Lexer/PH5P.php';
715 $config->set('Core', 'LexerImpl', 'PH5P');
716 Note that this Lexer introduces some classes not in the HTMLPurifier
717 namespace. Also, this is PHP5 only.
718 ! CSS property border-spacing implemented
719 - Fix non-visible parsing error in DirectLex with empty tags that have
720 slashes inside attribute values.
721 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
722 accepted as valid CSS. Usually non-visible, because this styling is the
723 default for tables in most browsers. Thanks Brett Zamir for pointing
725 - Fix validation errors in configuration form
726 - Hammer out a bunch of edge-case bugs in the standalone distribution
727 - Inclusion reflection removed from URISchemeRegistry; you must manually
728 include any new schema files you wish to use
729 - Numerous typo fixes in documentation thanks to Brett Zamir
730 . Unit test refactoring for one logical test per test function
731 . Config and context parameters in ComplexHarness deprecated: instead, edit
732 the $config and $context member variables
733 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
734 really make a difference, but is good for completeness sake
735 . merge-library.php script refactored for greater code reusability and
738 2.1.1, released 2007-08-04
739 - Fix show-stopper bug in %URI.MakeAbsolute functionality

742 other installations from clobbering the standalone's URI schemes
743 . Single test methods can be invoked by prefixing with __only
745 2.1.0, released 2007-08-02
746 # flush-htmldefinition-cache.php superseded in favor of a generic

748 by passing its name as a parameter to the script
749 ! Phorum mod implemented for HTML Purifier
750 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
751 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary

770 for output cache invalidation
771 . ConfigForm printer now can retrieve CSS and JS files as strings, in
772 case HTML Purifier's directory is not publically accessible
773 . Introduce new text/itext configuration directive values: these represent
774 longer strings that would be more appropriately edited with a textarea
775 . Allow newlines to act as separators for lists, hashes, lookups and
777 . ConfigForm generates textareas instead of text inputs for lists, hashes,
778 lookups, text and itext fields
779 . Hidden element content removal genericized: %Core.HiddenElements can
780 be used to customize this behavior, by default <script> and <style> are
782 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
783 . Custom ChildDef added to default include list
784 . URIScheme reflection improved: will not attempt to include file if class

798 maximum extensibility
800 2.0.1, released 2007-06-27
801 ! Tag auto-closing now based on a ChildDef heuristic rather than a
802 manually set auto_close array; some behavior may change
803 ! Experimental AutoFormat functionality added: auto-paragraph and
804 linkify your HTML input by setting %AutoFormat.AutoParagraph and
805 %AutoFormat.Linkify to true
806 ! Newlines normalized internally, and then converted back to the
807 value of PHP_EOL. If this is not desired, set your newline format
808 using %Output.Newline.
809 ! Beta error collection, messages are implemented for the most generic
810 cases involving Lexing or Strategies
811 - Clean up special case code for <script> tags
812 - Reorder includes for DefinitionCache decorators, fixes a possible
814 - Fixed bug where manually modified definitions were not saved via cache

831 . Interlinking in configuration documentation added using
832 Injector_PurifierLinkify
833 . Directives now keep track of aliases to themselves

837 much easier selective embedding of configuration values
838 . Doctype objects now accept public and system DTD identifiers
839 . %HTML.Doctype is now constrained by specific values, to specify a custom
840 doctype use new %HTML.CustomDoctype
841 . ConfigForm truncates long directives to keep the form small, and does
842 not re-output namespaces
844 2.0.0, released 2007-06-20
845 # Completely refactored HTMLModuleManager, decentralizing safety
847 # Transform modules changed to Tidy modules, which offer more flexibility
848 and better modularization
849 # Configuration object now finalizes itself when a read operation is
850 performed on it, ensuring that its internal state stays consistent.
851 To revert this behavior, you can set the $autoFinalize member variable
852 off, but it's not recommended.
853 # New compact syntax for AttrDef objects that can be used to instantiate
854 new objects via make()
855 # Definitions (esp. HTMLDefinition) are now cached for a significant
856 performance boost. You can disable caching by setting %Core.DefinitionCache
857 to null. You CANNOT edit raw definitions without setting the corresponding
858 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
859 # Contents between <script> tags are now completely removed if <script>
861 # Prototype-declarations for Lexer removed in favor of configuration

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

953 1.5.0, released 2007-03-23
954 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
955 doesn't actually do anything yet, but keep your eyes peeled.
956 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
957 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
