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

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

648 2.1.3, released 2007-11-05
649 ! tests/multitest.php allows you to test multiple versions by running
650 tests/index.php through multiple interpreters using `phpv` shell
651 script (you must provide this script!)
652 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
653 on some systems.
654 - Injector algorithm further refined: off-by-one error regarding skip
655 counts for dormant injectors fixed
656 - Corrective blockquote definition now enabled for HTML 4.01 Strict
657 - Fatal error when <img> tag (or any other element with required attributes)
658 has 'id' attribute fixed, thanks NykO18 for reporting
659 - Fix warning emitted when a non-supported URI scheme is passed to the
660 MakeAbsolute URIFilter, thanks NykO18 (again)
661 - Further refine AutoParagraph injector. Behavior inside of elements
662 allowing paragraph tags clarified: only inline content delimeted by
663 double newlines (not block elements) are paragraphed.
664 - Buggy treatment of end tags of elements that have required attributes
665 fixed (does not manifest on default tag-set)
666 - Spurious internal content reorganization error suppressed
667 - HTMLDefinition->addElement now returns a reference to the created
668 element object, as implied by the documentation
669 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
670 - Fix a theoretical class of infinite loops from DirectLex reported
671 by Nate Abele
672 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
673 in PHP 5.1
674 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
675 HTMLDefinition errors, this may indicate problems with error-collecting
676 facilities in PHP 5
677 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
678 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
679 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
680 to better communicate its purpose
681 . Error unit tests can now specify the expectation of no errors. Future
682 iterations of the harness will be extremely strict about what errors
683 are allowed
684 . Extend Injector hooks to allow for more powerful injector routines
685 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
686 method
687 . Doxygen configuration file updated, with minor improvements
688 . Test runner now checks for similarly named files in conf/ directory too.
689 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
690 outputted
691 . Maintenance script for generating PH5P patch added, original PH5P source
692 file also added under version control
693 . Full unit test runner script title made more descriptive with PHP version
694 . Updated INSTALL file to state that 4.3.7 is the earliest version we
695 are actively testing
697 2.1.2, released 2007-09-03
698 ! Implemented Object module for trusted users
699 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
700 this to your code:
701 require_once 'HTMLPurifier/Lexer/PH5P.php';
702 $config->set('Core', 'LexerImpl', 'PH5P');
703 Note that this Lexer introduces some classes not in the HTMLPurifier
704 namespace. Also, this is PHP5 only.
705 ! CSS property border-spacing implemented
706 - Fix non-visible parsing error in DirectLex with empty tags that have
707 slashes inside attribute values.
708 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
709 accepted as valid CSS. Usually non-visible, because this styling is the
710 default for tables in most browsers. Thanks Brett Zamir for pointing
711 this out.
712 - Fix validation errors in configuration form
713 - Hammer out a bunch of edge-case bugs in the standalone distribution
714 - Inclusion reflection removed from URISchemeRegistry; you must manually
715 include any new schema files you wish to use
716 - Numerous typo fixes in documentation thanks to Brett Zamir
717 . Unit test refactoring for one logical test per test function
718 . Config and context parameters in ComplexHarness deprecated: instead, edit
719 the $config and $context member variables
720 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
721 really make a difference, but is good for completeness sake
722 . merge-library.php script refactored for greater code reusability and
723 PHP4 compatibility
725 2.1.1, released 2007-08-04
726 - Fix show-stopper bug in %URI.MakeAbsolute functionality
727 - Fix PHP4 syntax error in standalone version

729 other installations from clobbering the standalone's URI schemes
730 . Single test methods can be invoked by prefixing with __only
732 2.1.0, released 2007-08-02
733 # flush-htmldefinition-cache.php superseded in favor of a generic
734 flush-definition-cache.php script, you can clear a specific cache
735 by passing its name as a parameter to the script
736 ! Phorum mod implemented for HTML Purifier
737 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
738 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
739 for PHP4 (DirectLex).
740 ! Standalone file now available, which greatly reduces the amount of
741 includes (although there are still a few files that reside in the
742 standalone folder)
743 ! Relative URIs can now be transformed into their absolute equivalents
744 using %URI.Base and %URI.MakeAbsolute
745 ! Ruby implemented for XHTML 1.1

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

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

898 are now preserved.
899 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
900 images will hang around with an empty src
901 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
902 to enable
903 ! CSS property white-space now allows nowrap (supported in all modern

934 %Attr.IDBlacklistRegexp
935 - Error messages are emitted when you attempt to "allow" elements or
936 attributes that HTML Purifier does not support
937 - Fix segfault in unit test. The problem is not very reproduceable and
938 I don't know what causes it, but a six line patch fixed it.
940 1.5.0, released 2007-03-23
941 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
942 doesn't actually do anything yet, but keep your eyes peeled.
943 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
944 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
945 I am loathe to release beta quality APIs, but this is exactly that;
946 don't use the internal interfaces if you're not willing to do migration
947 later on.
948 - Allow 'x' subtag in language codes
949 - Fixed buggy chameleon-support for ins and del
950 . Added support for IDREF attributes (i.e. for)
951 . Renamed HTMLPurifier_AttrDef_Class to HTMLPurifier_AttrDef_Nmtokens
952 . Removed context variable ParentType, replaced with IsInline, which
953 is false when you're not inline and an integer of the parent that
954 caused you to become inline when you are (so possibly zero)
955 . Removed ElementDef->type in favor of ElementDef->descendants_are_inline
956 and HTMLDefinition->content_sets
957 . StrictBlockquote now reports what elements its supposed to allow,
958 rather than what it does allow
959 . Removed HTMLDefinition->info_flow_elements in favor of
960 HTMLDefinition->content_sets['Flow']
961 . Removed redundant "exclusionary" definitions from DTD roster
962 . StrictBlockquote now requires a construction parameter as if it
963 were an Required ChildDef, this is the "real" set of allowed elements
964 . AttrDef partitioned into HTML, CSS and URI segments
965 . Modify Youtube filter regexp to be multiline
966 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
967 some edge cases where a DOMDocument class exists in a PHP4 environment
968 due to DOM XML extension.
