1 NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
5 # Breaks back-compat
6 ! Feature
7 - Bugfix
8 + Sub-comment
9 . Internal change
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 # By default, when a link has a target attribute associated
23 with it, we now also add rel="noopener" in order to
24 prevent the new window from being able to overwrite
25 the original frame. To disable this protection,
26 set %HTML.TargetNoopener to FALSE.
28 4.8.0, released 2016-07-16
29 # By default, when a link has a target attribute associated
30 with it, we now also add rel="noreferrer" in order to
31 prevent the new window from being able to overwrite
32 the original frame. To disable this protection,
33 set %HTML.TargetNoreferrer to FALSE.
34 ! Full PHP 7 compatibility, the test suite is ALL GO.
35 ! %CSS.AllowDuplicates permits duplicate CSS properties.
36 ! Support for 'tel' URIs.
37 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
38 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
39 yet supported.
40 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
41 - alt truncation could result in malformed UTF-8 sequence. Don't
42 truncate. Thanks Brandon Farber for reporting.
43 - Linkify regex is smarter, based off of Gruber's regex.
44 - IDNA supported natively on PHP 5.3 and later.
45 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
46 allowed.
47 - Minor bounds error fix to squash a PHP 7 notice.
48 - Support non-/tmp temporary directories for data:// validation
49 - Give a better error message when a user attempts to allow
50 ul/ol without allowing li.
51 - On some versions of PHP, the Serializer DefinitionCache could
52 infinite loop when the directory exists but is not listable. (#49)
53 - Don't match for <body> inside comments with
54 %Core.ConvertDocumentToFragment. (#67)
55 - SafeObject is now less case sensitive. (#57)
56 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
57 web form. (#85)
59 4.7.0, released 2015-08-04
60 # opacity is now considered a "tricky" CSS property rather than a
61 proprietary one.
62 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
63 an element should be considered "empty" (maybe preserve if it
64 has attributes), and modify iframe support so that the iframe
65 is removed if it is missing a src attribute. Thanks meeva for
66 reporting.
67 - Don't truncate upon encountering </div> when using DOMLex. Thanks
68 Myrto Christina for finally convincing me to fix this.
69 - Update YouTube filter for new code.
70 - Fix parsing of rgb() values with spaces in them for 'border'
71 attribute.
72 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
73 valME for reporting.
75 4.6.0, released 2013-11-30
76 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
77 Please update any verification scripts you may have.
78 # URI parsing algorithm was made more strict, so only prefixes which
79 looks like schemes will actually be schemes. Thanks
80 Michael Gusev <mgusev@sugarcrm.com> for fixing.
81 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
82 anything.
83 ! New directive %Core.AllowHostnameUnderscore which allows underscores
84 in hostnames.
85 - Eliminate quadratic behavior in DOMLex by using a proper queue.
86 Thanks Ole Laursen for noticing this.
87 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
88 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
89 Networks for sponsoring this work.
90 - Made Linkify URL parser a bit less permissive, so that non-breaking
91 spaces and commas are not included as part of URL. Thanks nAS for fixing.
92 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
93 David Hirtz for reporting.
94 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
95 for reporting.
97 4.5.0, released 2013-02-17
98 # Fix bug where stacked attribute transforms clobber each other;
99 this also means it's no longer possible to override attribute
100 transforms in later modules. No internal code was using this
101 but this may break some clients.
102 # We now use SHA-1 to identify cached definitions, instead of MD5.
103 ! Support display:inline-block
104 ! Support for more white-space CSS values.
105 ! Permit underscores in font families
106 ! Support for page-break-* CSS3 properties when proprietary properties
107 are enabled.
108 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
109 SGML excludes checking. If HTML Purifier is removing too much text
110 and you don't care about full standards compliance, try setting this to
111 'true'.
112 - Use prepend for SPL autoloading on PHP 5.3 and later.
113 - Fix bug with nofollow transform when pre-existing rel exists.
114 - Fix bug where background:url() always gets lower-cased
115 (but not background-image:url())
116 - Fix bug with non lower-case color names in HTML
117 - Fix bug where data URI validation doesn't remove temporary files.
118 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
119 - Don't remove certain empty tags on RemoveEmpty.
121 4.4.0, released 2012-01-18
122 # Removed PEARSax3 handler.
123 # URI.Munge now munges URIs inside the same host that go from https
124 to http. Reported by Neike Taika-Tessaro.
125 # Core.EscapeNonASCIICharacters now always transforms entities to
126 entities, even if target encoding is UTF-8.
127 # Tighten up selector validation in ExtractStyleBlocks.
128 Non-syntactically valid selectors are now rejected, along with
129 some of the more obscure ones such as attribute selectors, the
130 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
131 ID and class selectors now work properly with the relevant
132 configuration attributes. Also, mute errors when parsing CSS
133 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
134 ! Added support for 'scope' attribute on tables.
135 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
136 ! Properly handle sub-lists directly nested inside of lists in
137 a standards compliant way, by moving them into the preceding <li>
138 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
139 limited allowed comments in untrusted situations.
140 ! Implement iframes, and allow them to be used in untrusted mode with
141 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
142 <brad.froehle@gmail.com> for submitting an initial version of the patch.
143 ! The Forms module now works properly for transitional doctypes.
144 ! Added support for internationalized domain names. You need the PEAR
145 Net_IDNA2 module to be in your path; if it is installed, ensure the
146 class can be loaded and then set %Core.EnableIDNA to true.
147 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
148 <yramirez-htmlpurifier@adicio.com> for reporting.
149 - Explicitly initialize anonModule variable to null.
150 - Do not duplicate nofollow if already present. Thanks 178
151 for reporting.
152 - Do not add nofollow if hostname matches our current host. Thanks 178
153 for reporting, and Neike Taika-Tessaro for helping diagnose.
154 - Do not unset parser variable; this fixes intermittent serialization
155 problems. Thanks Neike Taika-Tessaro for reporting, bill
156 <10010tiger@gmail.com> for diagnosing.
157 - Fix iconv truncation bug, where non-UTF-8 target encodings see
158 output truncated after around 8000 characters. Thanks Jörg Ludwig
159 <joerg.ludwig@iserv.eu> for reporting.
160 - Fix broken table content model for XHTML1.1 (and also earlier
161 versions, although the W3C validator doesn't catch those violations).
162 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
164 4.3.0, released 2011-03-27
165 # Fixed broken caching of customized raw definitions, but requires an
166 API change. The old API still works but will emit a warning,
167 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
168 for how to upgrade your code.
169 # Protect against Internet Explorer innerHTML behavior by specially
170 treating attributes with backticks but no angled brackets, quotes or
171 spaces. This constitutes a slight semantic change, which can be
172 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
173 and Mario Heiderich.
174 # Protect against cssText/innerHTML by restricting allowed characters
175 used in fonts further than mandated by the specification and encoding
176 some extra special characters in URLs. Reported by Neike
177 Taika-Tessaro and Mario Heiderich.
178 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
179 ! More types of SPL autoloaders allowed on later versions of PHP.
180 ! Implementations for position, top, left, right, bottom, z-index
181 when %CSS.Trusted is on.
182 ! Add %Cache.SerializerPermissions option for custom serializer
183 directory/file permissions
184 ! Fix longstanding bug in Flash support for non-IE browsers, and
185 allow more wmode attributes.
186 ! Add %CSS.AllowedFonts to restrict permissible font names.
187 - Switch to an iterative traversal of the DOM, which prevents us
188 from running out of stack space for deeply nested documents.
189 Thanks Maxim Krizhanovsky for contributing a patch.
190 - Make removal of conditional IE comments ungreedy; thanks Bernd
191 for reporting.
192 - Escape CDATA before removing Internet Explorer comments.
193 - Fix removal of id attributes under certain conditions by ensuring
194 armor attributes are preserved when recreating tags.
195 - Check if schema.ser was corrupted.
196 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
197 This safety check is only done for HTMLPurifier.auto.php; if you
198 are using standalone or the specialized includes files, you're
199 expected to know what you're doing.
200 - Stop repeatedly writing the cache file after I'm done customizing a
201 raw definition. Reported by ajh.
202 - Switch to using require_once in the Bootstrap to work around bad
203 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
204 - Fix URI handling when hostname is missing but scheme is present.
205 Reported by Neike Taika-Tessaro.
206 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
207 for reporting.
208 - Fix harmless notice from indexing into empty string. Thanks Matthijs
209 Kooijman <matthijs@stdin.nl> for reporting.
210 - Don't autoclose no parent elements are able to support the element
211 that triggered the autoclose. In particular fixes strange behavior
212 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
213 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
215 4.2.0, released 2010-09-15
216 ! Added %Core.RemoveProcessingInstructions, which lets you remove
217 <? ... ?> statements.
218 ! Added %URI.DisableResources functionality; the directive originally
219 did nothing. Thanks David Rothstein for reporting.
220 ! Add documentation about configuration directive types.
221 ! Add %CSS.ForbiddenProperties configuration directive.
222 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
223 to utilize full-screen mode.
224 ! Add optional support for the <code>file</code> URI scheme, enable
225 by explicitly setting %URI.AllowedSchemes.
226 ! Add %Core.NormalizeNewlines options to allow turning off newline
227 normalization.
228 - Fix improper handling of Internet Explorer conditional comments
229 by parser. Thanks zmonteca for reporting.
230 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
231 Thanks sidepodcast for the fix.
232 - Warn if an element is allowed, but an attribute it requires is
233 not allowed.
235 4.1.1, released 2010-05-31
236 - Fix undefined index warnings in maintenance scripts.
237 - Fix bug in DirectLex for parsing elements with a single attribute
238 with entities.
239 - Rewrite CSS output logic for font-family and url(). Thanks Mario
240 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
241 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
242 - Emit an error for CollectErrors if a body is extracted
243 - Fix bug where in background-position for center keyword handling.
244 - Fix infinite loop when a wrapper element is inserted in a context
245 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
246 - Remove +x bit and shebang from index.php; only supported mode is to
247 explicitly call it with php.
248 - Make test script less chatty when log_errors is on.
250 4.1.0, released 2010-04-26
251 ! Support proprietary height attribute on table element
252 ! Support YouTube slideshows that contain /cp/ in their URL.
253 ! Support for data: URI scheme; not enabled by default, add it using
254 %URI.AllowedSchemes
255 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
256 ! Support for Internet Explorer compatibility with %HTML.SafeObject
257 using %Output.FlashCompat.
258 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
259 - Always quote the insides of url(...) in CSS.
261 4.0.0, released 2009-07-07
262 # APIs for ConfigSchema subsystem have substantially changed. See
263 docs/dev-config-bcbreaks.txt for details; in essence, anything that
264 had both namespace and directive now have a single unified key.
265 # Some configuration directives were renamed, specifically:
266 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
267 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
268 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
269 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
270 As usual, the old directive names will still work, but will throw E_NOTICE
271 errors.
272 # The allowed values for class have been relaxed to allow all of CDATA for
273 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
274 %Attr.ClassUseCDATA to false.
275 # Instead of appending the content model to an old content model, a blank
276 element will replace the old content model. You can use #SUPER to get
277 the old content model.
278 ! More robust support for name="" and id=""
279 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
280 configuration, and have changes to that configuration be propagated
281 to all of its children.
282 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
283 the name attribute when set. Use with care. Thanks Ian Cook for
284 sponsoring.
285 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
286 tags that contain non-breaking spaces as well other whitespace. You
287 can also modify which tags should have maintained with
288 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
289 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
290 classes users can use to a specified finite set of classes, and
291 %Attr.ForbiddenClasses, which is the logical inverse.
292 ! You can now maintain your own configuration schema directories by
293 creating a config-schema.php file or passing an extra argument. Check
294 docs/dev-config-schema.html for more details.
295 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
296 your configuration in a compact serial file, which you can unserialize
297 and use directly without having to go through the overhead of setup.
298 - Fix bug where URIDefinition would not get cleared if it's directives got
299 changed.
300 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
301 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
302 - Make %URI.Munge not apply to links that have the same host as your host.
303 - Prevent stray </body> tag from truncating output, if a second </body>
304 is present.
305 . Created script maintenance/rename-config.php for renaming a configuration
306 directive while maintaining its alias. This script does not change source code.
307 . Implement namespace locking for definition construction, to prevent
308 bugs where a directive is used for definition construction but is not
309 used to construct the cache hash.
311 3.3.0, released 2009-02-16
312 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
313 ! Implement generic property list classess
314 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
315 does not do the "right thing" with characters not supported in the output
316 set.
317 - Spellcheck UTF-8: The Secret To Character Encoding
318 - Fix improper removal of the contents of elements with only whitespace. Thanks
319 Eric Wald for reporting.
320 - Fix broken test suite in versions of PHP without spl_autoload_register()
321 - Fix degenerate case with YouTube filter involving double hyphens.
322 Thanks Pierre Attar for reporting.
323 - Fix YouTube rendering problem on certain versions of Firefox.
324 - Fix CSSDefinition Printer problems with decorators
325 - Add text parameter to unit tests, forces text output
326 . Add verbose mode to command line test runner, use (--verbose)
327 . Turn on unit tests for UnitConverter
328 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
329 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
330 tested on Linux.
331 . Removed trailing whitespace from all text files, see
332 remote-trailing-whitespace.php maintenance script.
333 . Convert configuration to use property list backend.
335 3.2.0, released 2008-10-31
336 # Using %Core.CollectErrors forces line number/column tracking on, whereas
337 previously you could theoretically turn it off.
338 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
339 use handleEnd() instead.
340 ! %Output.AttrSort for when you need your attributes in alphabetical order to
341 deal with a bug in FCKEditor. Requested by frank farmer.
342 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
343 ! Proper support for name attribute. It is now allowed and equivalent to the id
344 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
345 is heavy (for all doctypes).
346 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
347 use on hand-written HTML.
348 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
349 the strategy to be used, standalone, on untrusted input.
350 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
351 processing of left angled brackets in smileys and other whatnot.
352 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
353 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
354 the --only-phpt parameter, although for backwards-compatibility the flag
355 will still work.
356 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
357 Users who are not performing inbound filtering, this may seem a little
358 useless, but as a bonus, the test suite and handling of edge cases is also
359 improved.
360 ! Experimental implementation of forms for %HTML.Trusted
361 ! Track column numbers when maintain line numbers is on
362 ! Proprietary 'background' attribute on table-related elements converted into
363 corresponding CSS. Thanks Fusemail for sponsoring this feature!
364 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
365 supertype.
366 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
367 time of operation varies slightly from notifyEnd() as *all* end tokens are
368 processed by the injector before they are subject to the well-formedness rules.
369 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
370 basename of image when not present.
371 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
372 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
373 the other involving an undefined $is_folder error.
374 - Throw error when %Core.Encoding is set to a spurious value. Previously,
375 this errored silently and returned false.
376 - Redirected stderr to stdout for flush error output.
377 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
378 available.
379 - Do not re-munge URL if the output URL has the same host as the input URL.
380 Requested by Chris.
381 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
382 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
383 - Fix bug with inline elements in blockquotes conflicting with strict doctype
384 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
385 - Fix bug where dots and double-dots in absolute URLs without hostname were
386 not collapsed by URIFilter_MakeAbsolute.
387 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
388 by reordering their addition.
389 - Will now throw exception on many error conditions during lexer creation; also
390 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
391 is being used.
392 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
393 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
394 Reported by David Morton.
395 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
396 for more interesting filter-backtracking
397 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
398 index to reprocess tokens.
399 . StringHashParser now allows for multiline sections with "empty" content;
400 previously the section would remain undefined.
401 . Added --quick option to multitest.php, which tests only the most recent
402 release for each series.
403 . Added --distro option to multitest.php, which accepts either 'normal' or
404 'standalone'. This supercedes --exclude-normal and --exclude-standalone
406 3.1.1, released 2008-06-19
407 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
408 In order to enable this again, please set %URI.MungeResources to true.
409 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
410 and height/width HTML with %HTML.MaxImgLength.
411 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
412 for sponsoring this feature. Check out the corresponding documentation
413 for details. (Att Nightly testers: The API for this feature changed before
414 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
415 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
416 ! Implemented post URI filtering. Set member variable $post to true to set
417 a URIFilter as such.
418 ! Allow modules to define injectors via $info_injector. Injectors are
419 automatically disabled if injector's needed elements are not found.
420 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
421 Thanks Chris for sponsoring. If you've been using ad hoc code from the
422 forums, PLEASE use this instead.
423 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
424 embedded, tag name, attribute name, CSS property name). See %URI.Munge
425 for more details. Requested by Jochem Blok.
426 - Disable percent height/width attributes for img.
427 - AttrValidator operations are now atomic; updates to attributes are not
428 manifest in token until end of operations. This prevents naughty internal
429 code from directly modifying CurrentToken when they're not supposed to.
430 This semantics change was requested by frank farmer.
431 - Percent encoding checks enabled for URI query and fragment
432 - Fix stray backslashes in font-family; CSS Unicode character escapes are
433 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
434 for reporting.
435 - Improve parseCDATA algorithm to take into account newline normalization
436 - Account for browser confusion between Yen character and backslash in
437 Shift_JIS encoding. This fix generalizes to any other encoding which is not
438 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
439 - Fix missing configuration parameter in Generator calls. Thanks vs for the
440 partial patch.
441 - Improved adherence to Unicode by checking for non-character codepoints.
442 Thanks Geoffrey Sneddon for reporting. This may result in degraded
443 performance for extremely large inputs.
444 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
445 for reporting.
446 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
447 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
448 this class.
449 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
450 to __construct($min, $max). __construct(true) is equivalent to
451 __construct('0').
452 . Added HTMLPurifier_AttrDef_Switch class
453 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
454 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
455 get this called with the configuration object. All modules now
456 use this rather than __construct(), although legacy code using constructors
457 will still work--the new format, however, lets modules access the
458 configuration object for HTML namespace dependant tweaks.
459 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
460 . ConfigSchema data-structure heavily optimized; on average it uses a third
461 the memory it did previously. The interface has changed accordingly,
462 consult changes to HTMLPurifier_Config for details.
463 . Variable parsing types now are magic integers instead of strings
464 . Added benchmark for ConfigSchema
465 . HTMLPurifier_Generator requires $config and $context parameters. If you
466 don't know what they should be, use HTMLPurifier_Config::createDefault()
467 and new HTMLPurifier_Context().
468 . Printers now properly distinguish between output configuration, and
469 target configuration. This is not applicable to scripts using
470 the Printers for HTML Purifier related tasks.
471 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
472 fatal errors will ensue.
473 . URIFilter->prepare can return false in order to abort loading of the filter
474 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
475 an external resource.
476 . %URI.Munge functionality factored out into a post-filter class.
477 . Added CurrentCSSProperty context variable during CSS validation
479 3.1.0, released 2008-05-18
480 # Unnecessary references to objects (vestiges of PHP4) removed from method
481 signatures. The following methods do not need references when assigning from
482 them and will result in E_STRICT errors if you try:
483 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
484 + HTMLPurifier_ConfigSchema::instance()
485 + HTMLPurifier_DefinitionCacheFactory::instance()
486 + HTMLPurifier_DefinitionCacheFactory->create()
487 + HTMLPurifier_DoctypeRegistry->register()
488 + HTMLPurifier_DoctypeRegistry->get()
489 + HTMLPurifier_HTMLModule->addElement()
490 + HTMLPurifier_HTMLModule->addBlankElement()
491 + HTMLPurifier_LanguageFactory::instance()
492 # Printer_ConfigForm's get*() functions were static-ified
493 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
494 form of tag@attr, NOT tag.attr (which will throw an error and won't do
495 anything). This is for forwards compatibility with XML; you'd do best
496 to migrate an %HTML.AllowedAttributes directives to this syntax too.
497 ! Allow index to be false for config from form creation
498 ! Added HTMLPurifier::VERSION constant
499 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
500 and allows for version numbers like "3.1.0-dev".
501 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
502 ! HTML Purifier's URI handling is a lot more robust, with much stricter
503 validation checks and better percent encoding handling. Thanks Gareth Heyes
504 for indicating security vulnerabilities from lax percent encoding.
505 ! Bootstrap autoloader deals more robustly with classes that don't exist,
506 preventing class_exists($class, true) from barfing.
507 - InterchangeBuilder now alphabetizes its lists
508 - Validation error in configdoc output fixed
509 - Iconv and other encoding errors muted even with custom error handlers that
510 do not honor error_reporting
511 - Add protection against imagecrash attack with CSS height/width
512 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
513 - Fixed and revamped broken ConfigForm smoketest
514 - Bug with bool/null fields in Printer_ConfigForm fixed
515 - Bug with global forbidden attributes fixed
516 - Improved error messages for allowed and forbidden HTML elements and attributes
517 - Missing (or null) in configdoc documentation restored
518 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
519 of DOM), HTML Purifier punts to DirectLex
520 - Fatal error with unserialization of ScriptRequired
521 - Created directories are now chmod'ed properly
522 - Fixed bug with fallback languages in LanguageFactory
523 - Standalone testing setup properly with autoload
524 . Out-of-date documentation revised
525 . UTF-8 encoding check optimization as suggested by Diego
526 . HTMLPurifier_Error removed in favor of exceptions
527 . More copy() function removed; should use clone instead
528 . More extensive unit tests for HTMLDefinition
529 . assertPurification moved to central harness
530 . HTMLPurifier_Generator accepts $config and $context parameters during
531 instantiation, not runtime
532 . Double-quotes outside of attribute values are now unescaped
534 3.1.0rc1, released 2008-04-22
535 # Autoload support added. Internal require_once's removed in favor of an
536 explicit require list or autoloading. To use HTML Purifier,
537 you must now either use HTMLPurifier.auto.php
538 or HTMLPurifier.includes.php; setting the include path and including
539 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
540 as well to register our autoload handler (or modify your autoload function
541 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
542 HTMLPurifier.safe-includes.php for a less performance friendly but more
543 user-friendly library load.
544 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
545 information is stored in the ConfigSchema directory, and the
546 maintenance/generate-schema-cache.php generates the schema.ser file, which
547 is now instantiated. Support for userland schema changes coming soon!
548 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
549 alias; to get rid of these errors just modify your configuration to use
550 the new directive name.
551 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
552 enabled using %Filter.$filter_name or by setting your own filters using
553 %Filter.Custom
554 # Directive-level safety properties superceded in favor of module-level
555 safety. Internal method HTMLModule->addElement() has changed, although
556 the externally visible HTMLDefinition->addElement has *not* changed.
557 ! Extra utility classes for testing and non-library operations can
558 be found in extras/. Specifically, these are FSTools and ConfigDoc.
559 You may find a use for these in your own project, but right now they
560 are highly experimental and volatile.
561 ! Integration with PHPT allows for automated smoketests
562 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
563 by Chris. You can enable them with %HTML.Proprietary if your client
564 demands them.
565 ! Support for !important CSS cascade modifier. By default, this will be stripped
566 from CSS, but you can enable it using %CSS.AllowImportant
567 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
568 to true to use them.
569 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
570 Developer error (not enduser error) can cause these to be triggered.
571 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
572 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
573 mucking around with HTMLPurifier_CSSDefinition
574 ! ConfigDoc output has been enhanced with version and deprecation info.
575 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
576 - Autoclose now operates iteratively, i.e. <span><span><div> now has
577 both span tags closed.
578 - Various HTMLPurifier_Config convenience functions now accept another parameter
579 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
580 global default.
581 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
582 - Fix bug in ExtractStyleBlocks with comments in style tags
583 - Fix bug in comment parsing for DirectLex
584 - Flush output now displayed when in command line mode for unit tester
585 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
586 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
587 on the same element without emitting errors.
588 - Fixed fatal error in PH5P lexer with invalid tag names

590 . Convert tokens to use instanceof, reducing memory footprint and
591 improving comparison speed.
592 . Dry runs now supported in SimpleTest; testing facilities improved
593 . Bootstrap class added for handling autoloading functionality
594 . Implemented recursive glob at FSTools->globr
595 . ConfigSchema now has instance methods for all corresponding define*

599 . tests/index.php can now be run from any directory.
600 . HTMLPurifier_Token subclasses split into seperate files
601 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
602 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
603 . New --php=php flag added, allows PHP executable to be specified (command
604 line only!)
605 . htmlpurifier_add_test() preferred method to translate test files in to
606 classes, because it handles PHPT files too.
607 . Debugger class is deprecated and will be removed soon.
608 . Command line argument parsing for testing scripts revamped, now --opt value
609 format is supported.
610 . Smoketests now cleanup after magic quotes
611 . Generator now can output comments (however, comments are still stripped
612 from HTML Purifier output)
613 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
614 HTMLPurifier_VarParser->parse()
615 . Integers auto-cast into float type by VarParser.
616 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
617 during cache generation
618 . Reordered script calls in maintenance/flush.php
619 . Command line scripts now honor exit codes
620 . When --flush fails in unit testers, abort tests and print message
621 . Improved documentation in docs/dev-flush.html about the maintenance scripts
622 . copy() methods removed in favor of clone keyword
624 3.0.0, released 2008-01-06
625 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
626 until PHP 4 is completely deprecated, but no new features will be added
627 to it.
628 + Visibility declarations added
629 + Constructor methods renamed to __construct()
630 + PHP4 reference cruft removed (in progress)
631 ! CSS properties are now case-insensitive
632 ! DefinitionCacheFactory now can register new implementations
633 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
634 documents and cleaning their contents up. Requires the CSSTidy library
635 <http://csstidy.sourceforge.net/>. You can access the blocks with the
636 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
637 The output CSS can also be "scoped" for a specific element, use:
638 %Filter.ExtractStyleBlocksScope
639 ! Experimental support for some proprietary CSS attributes allowed:
640 opacity (and all of the browser-specific equivalents) and scrollbar colors.
641 Enable by setting %CSS.Proprietary to true.
642 - Colors missing # but in hex form will be corrected
643 - CSS Number algorithm improved
644 - Unit testing and multi-testing now on steroids: command lines,
645 XML output, and other goodies now added.

652 2.1.3, released 2007-11-05
653 ! tests/multitest.php allows you to test multiple versions by running
654 tests/index.php through multiple interpreters using `phpv` shell
655 script (you must provide this script!)
656 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
657 on some systems.
658 - Injector algorithm further refined: off-by-one error regarding skip
659 counts for dormant injectors fixed
660 - Corrective blockquote definition now enabled for HTML 4.01 Strict
661 - Fatal error when <img> tag (or any other element with required attributes)
662 has 'id' attribute fixed, thanks NykO18 for reporting
663 - Fix warning emitted when a non-supported URI scheme is passed to the
664 MakeAbsolute URIFilter, thanks NykO18 (again)
665 - Further refine AutoParagraph injector. Behavior inside of elements
666 allowing paragraph tags clarified: only inline content delimeted by
667 double newlines (not block elements) are paragraphed.
668 - Buggy treatment of end tags of elements that have required attributes
669 fixed (does not manifest on default tag-set)
670 - Spurious internal content reorganization error suppressed
671 - HTMLDefinition->addElement now returns a reference to the created
672 element object, as implied by the documentation
673 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
674 - Fix a theoretical class of infinite loops from DirectLex reported
675 by Nate Abele
676 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
677 in PHP 5.1
678 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
679 HTMLDefinition errors, this may indicate problems with error-collecting
680 facilities in PHP 5
681 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
682 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
683 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
684 to better communicate its purpose
685 . Error unit tests can now specify the expectation of no errors. Future
686 iterations of the harness will be extremely strict about what errors
687 are allowed
688 . Extend Injector hooks to allow for more powerful injector routines
689 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
690 method
691 . Doxygen configuration file updated, with minor improvements
692 . Test runner now checks for similarly named files in conf/ directory too.
693 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
694 outputted
695 . Maintenance script for generating PH5P patch added, original PH5P source
696 file also added under version control
697 . Full unit test runner script title made more descriptive with PHP version
698 . Updated INSTALL file to state that 4.3.7 is the earliest version we
699 are actively testing
701 2.1.2, released 2007-09-03
702 ! Implemented Object module for trusted users
703 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
704 this to your code:
705 require_once 'HTMLPurifier/Lexer/PH5P.php';
706 $config->set('Core', 'LexerImpl', 'PH5P');
707 Note that this Lexer introduces some classes not in the HTMLPurifier
708 namespace. Also, this is PHP5 only.
709 ! CSS property border-spacing implemented
710 - Fix non-visible parsing error in DirectLex with empty tags that have
711 slashes inside attribute values.
712 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
713 accepted as valid CSS. Usually non-visible, because this styling is the
714 default for tables in most browsers. Thanks Brett Zamir for pointing
715 this out.
716 - Fix validation errors in configuration form
717 - Hammer out a bunch of edge-case bugs in the standalone distribution
718 - Inclusion reflection removed from URISchemeRegistry; you must manually
719 include any new schema files you wish to use
720 - Numerous typo fixes in documentation thanks to Brett Zamir
721 . Unit test refactoring for one logical test per test function
722 . Config and context parameters in ComplexHarness deprecated: instead, edit
723 the $config and $context member variables
724 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
725 really make a difference, but is good for completeness sake
726 . merge-library.php script refactored for greater code reusability and
727 PHP4 compatibility
729 2.1.1, released 2007-08-04
730 - Fix show-stopper bug in %URI.MakeAbsolute functionality
731 - Fix PHP4 syntax error in standalone version

733 other installations from clobbering the standalone's URI schemes
734 . Single test methods can be invoked by prefixing with __only
736 2.1.0, released 2007-08-02
737 # flush-htmldefinition-cache.php superseded in favor of a generic
738 flush-definition-cache.php script, you can clear a specific cache
739 by passing its name as a parameter to the script
740 ! Phorum mod implemented for HTML Purifier
741 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
742 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
743 for PHP4 (DirectLex).
744 ! Standalone file now available, which greatly reduces the amount of
745 includes (although there are still a few files that reside in the
746 standalone folder)
747 ! Relative URIs can now be transformed into their absolute equivalents
748 using %URI.Base and %URI.MakeAbsolute
749 ! Ruby implemented for XHTML 1.1

759 - Contents of <style> tags removed by default when tags are removed
760 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
761 for output cache invalidation
762 . ConfigForm printer now can retrieve CSS and JS files as strings, in
763 case HTML Purifier's directory is not publically accessible
764 . Introduce new text/itext configuration directive values: these represent
765 longer strings that would be more appropriately edited with a textarea
766 . Allow newlines to act as separators for lists, hashes, lookups and
767 %HTML.Allowed
768 . ConfigForm generates textareas instead of text inputs for lists, hashes,
769 lookups, text and itext fields
770 . Hidden element content removal genericized: %Core.HiddenElements can
771 be used to customize this behavior, by default <script> and <style> are
772 hidden
773 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
774 . Custom ChildDef added to default include list
775 . URIScheme reflection improved: will not attempt to include file if class
776 already exists. May clobber autoload, so I need to keep an eye on it
777 . ConfigSchema heavily optimized, will only collect information and validate
778 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
779 . AttrDef_URI unit tests and implementation refactored
780 . benchmarks/ directory now protected from public view with .htaccess file;
781 run the tests via command line
782 . URI scheme is munged off if there is no authority and the scheme is the
783 default one
784 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
785 . Interface for URIScheme changed
786 . Generic URI object to hold components of URI added, most systems involved
787 in URI validation have been migrated to use it
788 . Custom filtering for URIs factored out to URIDefinition interface for
789 maximum extensibility
791 2.0.1, released 2007-06-27
792 ! Tag auto-closing now based on a ChildDef heuristic rather than a
793 manually set auto_close array; some behavior may change
794 ! Experimental AutoFormat functionality added: auto-paragraph and
795 linkify your HTML input by setting %AutoFormat.AutoParagraph and
796 %AutoFormat.Linkify to true
797 ! Newlines normalized internally, and then converted back to the
798 value of PHP_EOL. If this is not desired, set your newline format
799 using %Output.Newline.
800 ! Beta error collection, messages are implemented for the most generic
801 cases involving Lexing or Strategies
802 - Clean up special case code for <script> tags
803 - Reorder includes for DefinitionCache decorators, fixes a possible
804 missing class error
805 - Fixed bug where manually modified definitions were not saved via cache

807 - Configuration objects with different serials do not clobber each
808 others when revision numbers are unequal
809 - Improve Serializer DefinitionCache directory permissions checks
810 - DefinitionCache no longer throws errors when it encounters old
811 serial files that do not conform to the current style
812 - Stray xmlns attributes removed from configuration documentation

814 unescaped print_r output
815 - Printer adheres to configuration's directives on output format
816 - Fix improperly named form field in ConfigForm printer
817 . Rewire some test-cases to swallow errors rather than expect them
818 . HTMLDefinition printer updated with some of the new attributes
819 . DefinitionCache keys reordered to reflect precedence: version number,
820 hash, then revision number
821 . %Core.DefinitionCache renamed to %Cache.DefinitionImpl
822 . Interlinking in configuration documentation added using
823 Injector_PurifierLinkify
824 . Directives now keep track of aliases to themselves
825 . Error collector now requires a severity to be passed, use PHP's internal
826 error constants for this
827 . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
828 much easier selective embedding of configuration values
829 . Doctype objects now accept public and system DTD identifiers
830 . %HTML.Doctype is now constrained by specific values, to specify a custom
831 doctype use new %HTML.CustomDoctype
832 . ConfigForm truncates long directives to keep the form small, and does
833 not re-output namespaces
835 2.0.0, released 2007-06-20
836 # Completely refactored HTMLModuleManager, decentralizing safety
837 information
838 # Transform modules changed to Tidy modules, which offer more flexibility
839 and better modularization
840 # Configuration object now finalizes itself when a read operation is
841 performed on it, ensuring that its internal state stays consistent.
842 To revert this behavior, you can set the $autoFinalize member variable
843 off, but it's not recommended.
844 # New compact syntax for AttrDef objects that can be used to instantiate
845 new objects via make()
846 # Definitions (esp. HTMLDefinition) are now cached for a significant
847 performance boost. You can disable caching by setting %Core.DefinitionCache
848 to null. You CANNOT edit raw definitions without setting the corresponding
849 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
850 # Contents between <script> tags are now completely removed if <script>
851 is not allowed
852 # Prototype-declarations for Lexer removed in favor of configuration
853 determination of Lexer implementations.

870 - StrictBlockquote child definition refrains from wrapping whitespace
871 in tags now.
872 - Bug resulting from tag transforms to non-allowed elements fixed
873 - ChildDef_Custom's regex generation has been improved, removing several
874 false positives
875 . Unit test for ElementDef created, ElementDef behavior modified to
876 be more flexible

896 + nowrap in td
897 + clear in br
898 + align in caption, table, img and hr
899 + type in ul, ol and li
900 ! DirectLex now preserves text in which a < bracket is followed by

902 are now preserved.
903 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
904 images will hang around with an empty src
905 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
906 to enable
907 ! CSS property white-space now allows nowrap (supported in all modern
908 browsers) but not others (which have spotty browser implementations)

938 %Attr.IDBlacklistRegexp
939 - Error messages are emitted when you attempt to "allow" elements or
940 attributes that HTML Purifier does not support

944 1.5.0, released 2007-03-23
945 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
946 doesn't actually do anything yet, but keep your eyes peeled.

948 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.

950 don't use the internal interfaces if you're not willing to do migration
951 later on.

960 and HTMLDefinition->content_sets

969 . Modify Youtube filter regexp to be multiline
970 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
