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 4.8.0, released 2016-07-16
13 # By default, when a link has a target attribute associated
14 with it, we now also add rel="noreferrer" in order to
15 prevent the new window from being able to overwrite
16 the original frame. To disable this protection,
17 set %HTML.TargetNoreferrer to FALSE.
18 ! Full PHP 7 compatibility, the test suite is ALL GO.
19 ! %CSS.AllowDuplicates permits duplicate CSS properties.
20 ! Support for 'tel' URIs.
21 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
22 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
23 yet supported.
24 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
25 - alt truncation could result in malformed UTF-8 sequence. Don't
26 truncate. Thanks Brandon Farber for reporting.
27 - Linkify regex is smarter, based off of Gruber's regex.
28 - IDNA supported natively on PHP 5.3 and later.
29 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
30 allowed.
31 - Minor bounds error fix to squash a PHP 7 notice.
32 - Support non-/tmp temporary directories for data:// validation
33 - Give a better error message when a user attempts to allow
34 ul/ol without allowing li.
35 - On some versions of PHP, the Serializer DefinitionCache could
36 infinite loop when the directory exists but is not listable. (#49)
37 - Don't match for <body> inside comments with
38 %Core.ConvertDocumentToFragment. (#67)
39 - SafeObject is now less case sensitive. (#57)
40 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
41 web form. (#85)
43 4.7.0, released 2015-08-04
44 # opacity is now considered a "tricky" CSS property rather than a
45 proprietary one.
46 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
47 an element should be considered "empty" (maybe preserve if it
48 has attributes), and modify iframe support so that the iframe
49 is removed if it is missing a src attribute. Thanks meeva for
50 reporting.
51 - Don't truncate upon encountering </div> when using DOMLex. Thanks
52 Myrto Christina for finally convincing me to fix this.
53 - Update YouTube filter for new code.
54 - Fix parsing of rgb() values with spaces in them for 'border'
55 attribute.
56 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
57 valME for reporting.
59 4.6.0, released 2013-11-30
60 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
61 Please update any verification scripts you may have.
62 # URI parsing algorithm was made more strict, so only prefixes which
63 looks like schemes will actually be schemes. Thanks
64 Michael Gusev <mgusev@sugarcrm.com> for fixing.
65 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
66 anything.
67 ! New directive %Core.AllowHostnameUnderscore which allows underscores
68 in hostnames.
69 - Eliminate quadratic behavior in DOMLex by using a proper queue.
70 Thanks Ole Laursen for noticing this.
71 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
72 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
73 Networks for sponsoring this work.
74 - Made Linkify URL parser a bit less permissive, so that non-breaking
75 spaces and commas are not included as part of URL. Thanks nAS for fixing.
76 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
77 David Hirtz for reporting.
78 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
79 for reporting.
81 4.5.0, released 2013-02-17
82 # Fix bug where stacked attribute transforms clobber each other;
83 this also means it's no longer possible to override attribute
84 transforms in later modules. No internal code was using this
85 but this may break some clients.
86 # We now use SHA-1 to identify cached definitions, instead of MD5.
87 ! Support display:inline-block
88 ! Support for more white-space CSS values.
89 ! Permit underscores in font families
90 ! Support for page-break-* CSS3 properties when proprietary properties
91 are enabled.
92 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
93 SGML excludes checking. If HTML Purifier is removing too much text
94 and you don't care about full standards compliance, try setting this to
95 'true'.
96 - Use prepend for SPL autoloading on PHP 5.3 and later.
97 - Fix bug with nofollow transform when pre-existing rel exists.
98 - Fix bug where background:url() always gets lower-cased
99 (but not background-image:url())
100 - Fix bug with non lower-case color names in HTML
101 - Fix bug where data URI validation doesn't remove temporary files.
102 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
103 - Don't remove certain empty tags on RemoveEmpty.
105 4.4.0, released 2012-01-18
106 # Removed PEARSax3 handler.
107 # URI.Munge now munges URIs inside the same host that go from https
108 to http. Reported by Neike Taika-Tessaro.
109 # Core.EscapeNonASCIICharacters now always transforms entities to
110 entities, even if target encoding is UTF-8.
111 # Tighten up selector validation in ExtractStyleBlocks.
112 Non-syntactically valid selectors are now rejected, along with
113 some of the more obscure ones such as attribute selectors, the
114 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
115 ID and class selectors now work properly with the relevant
116 configuration attributes. Also, mute errors when parsing CSS
117 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
118 ! Added support for 'scope' attribute on tables.
119 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
120 ! Properly handle sub-lists directly nested inside of lists in
121 a standards compliant way, by moving them into the preceding <li>
122 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
123 limited allowed comments in untrusted situations.
124 ! Implement iframes, and allow them to be used in untrusted mode with
125 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
126 <brad.froehle@gmail.com> for submitting an initial version of the patch.
127 ! The Forms module now works properly for transitional doctypes.
128 ! Added support for internationalized domain names. You need the PEAR
129 Net_IDNA2 module to be in your path; if it is installed, ensure the
130 class can be loaded and then set %Core.EnableIDNA to true.
131 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
132 <yramirez-htmlpurifier@adicio.com> for reporting.
133 - Explicitly initialize anonModule variable to null.
134 - Do not duplicate nofollow if already present. Thanks 178
135 for reporting.
136 - Do not add nofollow if hostname matches our current host. Thanks 178
137 for reporting, and Neike Taika-Tessaro for helping diagnose.
138 - Do not unset parser variable; this fixes intermittent serialization
139 problems. Thanks Neike Taika-Tessaro for reporting, bill
140 <10010tiger@gmail.com> for diagnosing.
141 - Fix iconv truncation bug, where non-UTF-8 target encodings see
142 output truncated after around 8000 characters. Thanks Jörg Ludwig
143 <joerg.ludwig@iserv.eu> for reporting.
144 - Fix broken table content model for XHTML1.1 (and also earlier
145 versions, although the W3C validator doesn't catch those violations).
146 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
148 4.3.0, released 2011-03-27
149 # Fixed broken caching of customized raw definitions, but requires an
150 API change. The old API still works but will emit a warning,
151 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
152 for how to upgrade your code.
153 # Protect against Internet Explorer innerHTML behavior by specially
154 treating attributes with backticks but no angled brackets, quotes or
155 spaces. This constitutes a slight semantic change, which can be
156 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
157 and Mario Heiderich.
158 # Protect against cssText/innerHTML by restricting allowed characters
159 used in fonts further than mandated by the specification and encoding
160 some extra special characters in URLs. Reported by Neike
161 Taika-Tessaro and Mario Heiderich.
162 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
163 ! More types of SPL autoloaders allowed on later versions of PHP.
164 ! Implementations for position, top, left, right, bottom, z-index
165 when %CSS.Trusted is on.
166 ! Add %Cache.SerializerPermissions option for custom serializer
167 directory/file permissions
168 ! Fix longstanding bug in Flash support for non-IE browsers, and
169 allow more wmode attributes.
170 ! Add %CSS.AllowedFonts to restrict permissible font names.
171 - Switch to an iterative traversal of the DOM, which prevents us
172 from running out of stack space for deeply nested documents.
173 Thanks Maxim Krizhanovsky for contributing a patch.
174 - Make removal of conditional IE comments ungreedy; thanks Bernd
175 for reporting.
176 - Escape CDATA before removing Internet Explorer comments.
177 - Fix removal of id attributes under certain conditions by ensuring
178 armor attributes are preserved when recreating tags.
179 - Check if schema.ser was corrupted.
180 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
181 This safety check is only done for HTMLPurifier.auto.php; if you
182 are using standalone or the specialized includes files, you're
183 expected to know what you're doing.
184 - Stop repeatedly writing the cache file after I'm done customizing a
185 raw definition. Reported by ajh.
186 - Switch to using require_once in the Bootstrap to work around bad
187 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
188 - Fix URI handling when hostname is missing but scheme is present.
189 Reported by Neike Taika-Tessaro.
190 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
191 for reporting.
192 - Fix harmless notice from indexing into empty string. Thanks Matthijs
193 Kooijman <matthijs@stdin.nl> for reporting.
194 - Don't autoclose no parent elements are able to support the element
195 that triggered the autoclose. In particular fixes strange behavior
196 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
197 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
199 4.2.0, released 2010-09-15
200 ! Added %Core.RemoveProcessingInstructions, which lets you remove
201 <? ... ?> statements.
202 ! Added %URI.DisableResources functionality; the directive originally
203 did nothing. Thanks David Rothstein for reporting.
204 ! Add documentation about configuration directive types.
205 ! Add %CSS.ForbiddenProperties configuration directive.
206 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
207 to utilize full-screen mode.
208 ! Add optional support for the <code>file</code> URI scheme, enable
209 by explicitly setting %URI.AllowedSchemes.
210 ! Add %Core.NormalizeNewlines options to allow turning off newline
211 normalization.
212 - Fix improper handling of Internet Explorer conditional comments
213 by parser. Thanks zmonteca for reporting.
214 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
215 Thanks sidepodcast for the fix.
216 - Warn if an element is allowed, but an attribute it requires is
217 not allowed.
219 4.1.1, released 2010-05-31
220 - Fix undefined index warnings in maintenance scripts.
221 - Fix bug in DirectLex for parsing elements with a single attribute
222 with entities.
223 - Rewrite CSS output logic for font-family and url(). Thanks Mario
224 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
225 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
226 - Emit an error for CollectErrors if a body is extracted
227 - Fix bug where in background-position for center keyword handling.
228 - Fix infinite loop when a wrapper element is inserted in a context
229 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
230 - Remove +x bit and shebang from index.php; only supported mode is to
231 explicitly call it with php.
232 - Make test script less chatty when log_errors is on.
234 4.1.0, released 2010-04-26
235 ! Support proprietary height attribute on table element
236 ! Support YouTube slideshows that contain /cp/ in their URL.
237 ! Support for data: URI scheme; not enabled by default, add it using
238 %URI.AllowedSchemes
239 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
240 ! Support for Internet Explorer compatibility with %HTML.SafeObject
241 using %Output.FlashCompat.
242 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
243 - Always quote the insides of url(...) in CSS.
245 4.0.0, released 2009-07-07
246 # APIs for ConfigSchema subsystem have substantially changed. See
247 docs/dev-config-bcbreaks.txt for details; in essence, anything that
248 had both namespace and directive now have a single unified key.
249 # Some configuration directives were renamed, specifically:
250 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
251 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
252 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
253 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
254 As usual, the old directive names will still work, but will throw E_NOTICE
255 errors.
256 # The allowed values for class have been relaxed to allow all of CDATA for
257 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
258 %Attr.ClassUseCDATA to false.
259 # Instead of appending the content model to an old content model, a blank
260 element will replace the old content model. You can use #SUPER to get
261 the old content model.
262 ! More robust support for name="" and id=""
263 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
264 configuration, and have changes to that configuration be propagated
265 to all of its children.
266 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
267 the name attribute when set. Use with care. Thanks Ian Cook for
268 sponsoring.
269 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
270 tags that contain non-breaking spaces as well other whitespace. You
271 can also modify which tags should have maintained with
272 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
273 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
274 classes users can use to a specified finite set of classes, and
275 %Attr.ForbiddenClasses, which is the logical inverse.
276 ! You can now maintain your own configuration schema directories by
277 creating a config-schema.php file or passing an extra argument. Check
278 docs/dev-config-schema.html for more details.
279 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
280 your configuration in a compact serial file, which you can unserialize
281 and use directly without having to go through the overhead of setup.
282 - Fix bug where URIDefinition would not get cleared if it's directives got
283 changed.
284 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
285 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
286 - Make %URI.Munge not apply to links that have the same host as your host.
287 - Prevent stray </body> tag from truncating output, if a second </body>
288 is present.
289 . Created script maintenance/rename-config.php for renaming a configuration
290 directive while maintaining its alias. This script does not change source code.
291 . Implement namespace locking for definition construction, to prevent
292 bugs where a directive is used for definition construction but is not
293 used to construct the cache hash.
295 3.3.0, released 2009-02-16
296 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
297 ! Implement generic property list classess
298 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
299 does not do the "right thing" with characters not supported in the output
300 set.
301 - Spellcheck UTF-8: The Secret To Character Encoding
302 - Fix improper removal of the contents of elements with only whitespace. Thanks
303 Eric Wald for reporting.
304 - Fix broken test suite in versions of PHP without spl_autoload_register()
305 - Fix degenerate case with YouTube filter involving double hyphens.
306 Thanks Pierre Attar for reporting.
307 - Fix YouTube rendering problem on certain versions of Firefox.
308 - Fix CSSDefinition Printer problems with decorators
309 - Add text parameter to unit tests, forces text output
310 . Add verbose mode to command line test runner, use (--verbose)
311 . Turn on unit tests for UnitConverter
312 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
313 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
314 tested on Linux.
315 . Removed trailing whitespace from all text files, see
316 remote-trailing-whitespace.php maintenance script.
317 . Convert configuration to use property list backend.
319 3.2.0, released 2008-10-31
320 # Using %Core.CollectErrors forces line number/column tracking on, whereas
321 previously you could theoretically turn it off.
322 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
323 use handleEnd() instead.
324 ! %Output.AttrSort for when you need your attributes in alphabetical order to
325 deal with a bug in FCKEditor. Requested by frank farmer.
326 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
327 ! Proper support for name attribute. It is now allowed and equivalent to the id
328 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
329 is heavy (for all doctypes).
330 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
331 use on hand-written HTML.
332 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
333 the strategy to be used, standalone, on untrusted input.
334 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
335 processing of left angled brackets in smileys and other whatnot.
336 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
337 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
338 the --only-phpt parameter, although for backwards-compatibility the flag
339 will still work.
340 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
341 Users who are not performing inbound filtering, this may seem a little
342 useless, but as a bonus, the test suite and handling of edge cases is also
343 improved.
344 ! Experimental implementation of forms for %HTML.Trusted
345 ! Track column numbers when maintain line numbers is on
346 ! Proprietary 'background' attribute on table-related elements converted into
347 corresponding CSS. Thanks Fusemail for sponsoring this feature!
348 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
349 supertype.
350 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
351 time of operation varies slightly from notifyEnd() as *all* end tokens are
352 processed by the injector before they are subject to the well-formedness rules.
353 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
354 basename of image when not present.
355 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
356 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
357 the other involving an undefined $is_folder error.
358 - Throw error when %Core.Encoding is set to a spurious value. Previously,
359 this errored silently and returned false.
360 - Redirected stderr to stdout for flush error output.
361 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
362 available.
363 - Do not re-munge URL if the output URL has the same host as the input URL.
364 Requested by Chris.
365 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
366 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
367 - Fix bug with inline elements in blockquotes conflicting with strict doctype
368 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
369 - Fix bug where dots and double-dots in absolute URLs without hostname were
370 not collapsed by URIFilter_MakeAbsolute.
371 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
372 by reordering their addition.
373 - Will now throw exception on many error conditions during lexer creation; also
374 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
375 is being used.
376 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
377 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
378 Reported by David Morton.
379 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
380 for more interesting filter-backtracking
381 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
382 index to reprocess tokens.
383 . StringHashParser now allows for multiline sections with "empty" content;
384 previously the section would remain undefined.
385 . Added --quick option to multitest.php, which tests only the most recent
386 release for each series.
387 . Added --distro option to multitest.php, which accepts either 'normal' or
388 'standalone'. This supercedes --exclude-normal and --exclude-standalone
390 3.1.1, released 2008-06-19
391 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
392 In order to enable this again, please set %URI.MungeResources to true.
393 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
394 and height/width HTML with %HTML.MaxImgLength.
395 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
396 for sponsoring this feature. Check out the corresponding documentation
397 for details. (Att Nightly testers: The API for this feature changed before
398 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
399 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
400 ! Implemented post URI filtering. Set member variable $post to true to set
401 a URIFilter as such.
402 ! Allow modules to define injectors via $info_injector. Injectors are
403 automatically disabled if injector's needed elements are not found.
404 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
405 Thanks Chris for sponsoring. If you've been using ad hoc code from the
406 forums, PLEASE use this instead.
407 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
408 embedded, tag name, attribute name, CSS property name). See %URI.Munge
409 for more details. Requested by Jochem Blok.
410 - Disable percent height/width attributes for img.
411 - AttrValidator operations are now atomic; updates to attributes are not
412 manifest in token until end of operations. This prevents naughty internal
413 code from directly modifying CurrentToken when they're not supposed to.
414 This semantics change was requested by frank farmer.
415 - Percent encoding checks enabled for URI query and fragment
416 - Fix stray backslashes in font-family; CSS Unicode character escapes are
417 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
418 for reporting.
419 - Improve parseCDATA algorithm to take into account newline normalization
420 - Account for browser confusion between Yen character and backslash in
421 Shift_JIS encoding. This fix generalizes to any other encoding which is not
422 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
423 - Fix missing configuration parameter in Generator calls. Thanks vs for the
424 partial patch.
425 - Improved adherence to Unicode by checking for non-character codepoints.
426 Thanks Geoffrey Sneddon for reporting. This may result in degraded
427 performance for extremely large inputs.
428 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
429 for reporting.
430 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
431 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
432 this class.
433 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
434 to __construct($min, $max). __construct(true) is equivalent to
435 __construct('0').
436 . Added HTMLPurifier_AttrDef_Switch class
437 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
438 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
439 get this called with the configuration object. All modules now
440 use this rather than __construct(), although legacy code using constructors
441 will still work--the new format, however, lets modules access the
442 configuration object for HTML namespace dependant tweaks.
443 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
444 . ConfigSchema data-structure heavily optimized; on average it uses a third
445 the memory it did previously. The interface has changed accordingly,
446 consult changes to HTMLPurifier_Config for details.
447 . Variable parsing types now are magic integers instead of strings
448 . Added benchmark for ConfigSchema
449 . HTMLPurifier_Generator requires $config and $context parameters. If you
450 don't know what they should be, use HTMLPurifier_Config::createDefault()
451 and new HTMLPurifier_Context().
452 . Printers now properly distinguish between output configuration, and
453 target configuration. This is not applicable to scripts using
454 the Printers for HTML Purifier related tasks.
455 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
456 fatal errors will ensue.
457 . URIFilter->prepare can return false in order to abort loading of the filter
458 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
459 an external resource.
460 . %URI.Munge functionality factored out into a post-filter class.
461 . Added CurrentCSSProperty context variable during CSS validation
463 3.1.0, released 2008-05-18
464 # Unnecessary references to objects (vestiges of PHP4) removed from method
465 signatures. The following methods do not need references when assigning from
466 them and will result in E_STRICT errors if you try:
467 + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
468 + HTMLPurifier_ConfigSchema::instance()
469 + HTMLPurifier_DefinitionCacheFactory::instance()
470 + HTMLPurifier_DefinitionCacheFactory->create()
471 + HTMLPurifier_DoctypeRegistry->register()
472 + HTMLPurifier_DoctypeRegistry->get()
473 + HTMLPurifier_HTMLModule->addElement()
474 + HTMLPurifier_HTMLModule->addBlankElement()
475 + HTMLPurifier_LanguageFactory::instance()
476 # Printer_ConfigForm's get*() functions were static-ified
477 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
478 form of tag@attr, NOT tag.attr (which will throw an error and won't do
479 anything). This is for forwards compatibility with XML; you'd do best
480 to migrate an %HTML.AllowedAttributes directives to this syntax too.
481 ! Allow index to be false for config from form creation
482 ! Added HTMLPurifier::VERSION constant
483 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
484 and allows for version numbers like "3.1.0-dev".
485 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
486 ! HTML Purifier's URI handling is a lot more robust, with much stricter
487 validation checks and better percent encoding handling. Thanks Gareth Heyes
488 for indicating security vulnerabilities from lax percent encoding.
489 ! Bootstrap autoloader deals more robustly with classes that don't exist,
490 preventing class_exists($class, true) from barfing.
491 - InterchangeBuilder now alphabetizes its lists
492 - Validation error in configdoc output fixed
493 - Iconv and other encoding errors muted even with custom error handlers that
494 do not honor error_reporting
495 - Add protection against imagecrash attack with CSS height/width
496 - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
497 - Fixed and revamped broken ConfigForm smoketest
498 - Bug with bool/null fields in Printer_ConfigForm fixed
499 - Bug with global forbidden attributes fixed
500 - Improved error messages for allowed and forbidden HTML elements and attributes
501 - Missing (or null) in configdoc documentation restored
502 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
503 of DOM), HTML Purifier punts to DirectLex
504 - Fatal error with unserialization of ScriptRequired
505 - Created directories are now chmod'ed properly
506 - Fixed bug with fallback languages in LanguageFactory
507 - Standalone testing setup properly with autoload
508 . Out-of-date documentation revised
509 . UTF-8 encoding check optimization as suggested by Diego
510 . HTMLPurifier_Error removed in favor of exceptions
511 . More copy() function removed; should use clone instead
512 . More extensive unit tests for HTMLDefinition
513 . assertPurification moved to central harness
514 . HTMLPurifier_Generator accepts $config and $context parameters during
515 instantiation, not runtime
516 . Double-quotes outside of attribute values are now unescaped
518 3.1.0rc1, released 2008-04-22
519 # Autoload support added. Internal require_once's removed in favor of an
520 explicit require list or autoloading. To use HTML Purifier,
521 you must now either use HTMLPurifier.auto.php
522 or HTMLPurifier.includes.php; setting the include path and including
523 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
524 as well to register our autoload handler (or modify your autoload function
525 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
526 HTMLPurifier.safe-includes.php for a less performance friendly but more
527 user-friendly library load.
528 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
529 information is stored in the ConfigSchema directory, and the
530 maintenance/generate-schema-cache.php generates the schema.ser file, which
531 is now instantiated. Support for userland schema changes coming soon!
532 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
533 alias; to get rid of these errors just modify your configuration to use
534 the new directive name.
535 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
536 enabled using %Filter.$filter_name or by setting your own filters using
537 %Filter.Custom
538 # Directive-level safety properties superceded in favor of module-level
539 safety. Internal method HTMLModule->addElement() has changed, although
540 the externally visible HTMLDefinition->addElement has *not* changed.
541 ! Extra utility classes for testing and non-library operations can
542 be found in extras/. Specifically, these are FSTools and ConfigDoc.
543 You may find a use for these in your own project, but right now they
544 are highly experimental and volatile.
545 ! Integration with PHPT allows for automated smoketests
546 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
547 by Chris. You can enable them with %HTML.Proprietary if your client
548 demands them.
549 ! Support for !important CSS cascade modifier. By default, this will be stripped
550 from CSS, but you can enable it using %CSS.AllowImportant
551 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
552 to true to use them.
553 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
554 Developer error (not enduser error) can cause these to be triggered.
555 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
556 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
557 mucking around with HTMLPurifier_CSSDefinition
558 ! ConfigDoc output has been enhanced with version and deprecation info.
559 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
560 - Autoclose now operates iteratively, i.e. <span><span><div> now has
561 both span tags closed.
562 - Various HTMLPurifier_Config convenience functions now accept another parameter
563 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
564 global default.
565 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
566 - Fix bug in ExtractStyleBlocks with comments in style tags
567 - Fix bug in comment parsing for DirectLex
568 - Flush output now displayed when in command line mode for unit tester
569 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
570 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
571 on the same element without emitting errors.
572 - Fixed fatal error in PH5P lexer with invalid tag names

574 . Convert tokens to use instanceof, reducing memory footprint and
575 improving comparison speed.
576 . Dry runs now supported in SimpleTest; testing facilities improved
577 . Bootstrap class added for handling autoloading functionality
578 . Implemented recursive glob at FSTools->globr
579 . ConfigSchema now has instance methods for all corresponding define*

586 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
587 . New --php=php flag added, allows PHP executable to be specified (command
588 line only!)
589 . htmlpurifier_add_test() preferred method to translate test files in to
590 classes, because it handles PHPT files too.
591 . Debugger class is deprecated and will be removed soon.
592 . Command line argument parsing for testing scripts revamped, now --opt value
593 format is supported.
594 . Smoketests now cleanup after magic quotes
595 . Generator now can output comments (however, comments are still stripped
596 from HTML Purifier output)
597 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
598 HTMLPurifier_VarParser->parse()
599 . Integers auto-cast into float type by VarParser.
600 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
601 during cache generation
602 . Reordered script calls in maintenance/flush.php
603 . Command line scripts now honor exit codes
604 . When --flush fails in unit testers, abort tests and print message
605 . Improved documentation in docs/dev-flush.html about the maintenance scripts
606 . copy() methods removed in favor of clone keyword
608 3.0.0, released 2008-01-06
609 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
610 until PHP 4 is completely deprecated, but no new features will be added
611 to it.
612 + Visibility declarations added
613 + Constructor methods renamed to __construct()
614 + PHP4 reference cruft removed (in progress)
615 ! CSS properties are now case-insensitive

617 ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
618 documents and cleaning their contents up. Requires the CSSTidy library
619 <http://csstidy.sourceforge.net/>. You can access the blocks with the
620 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
621 The output CSS can also be "scoped" for a specific element, use:
622 %Filter.ExtractStyleBlocksScope
623 ! Experimental support for some proprietary CSS attributes allowed:
624 opacity (and all of the browser-specific equivalents) and scrollbar colors.
625 Enable by setting %CSS.Proprietary to true.
626 - Colors missing # but in hex form will be corrected

636 2.1.3, released 2007-11-05
637 ! tests/multitest.php allows you to test multiple versions by running
638 tests/index.php through multiple interpreters using `phpv` shell
639 script (you must provide this script!)
640 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
641 on some systems.
642 - Injector algorithm further refined: off-by-one error regarding skip
643 counts for dormant injectors fixed
644 - Corrective blockquote definition now enabled for HTML 4.01 Strict
645 - Fatal error when <img> tag (or any other element with required attributes)
646 has 'id' attribute fixed, thanks NykO18 for reporting
647 - Fix warning emitted when a non-supported URI scheme is passed to the
648 MakeAbsolute URIFilter, thanks NykO18 (again)
649 - Further refine AutoParagraph injector. Behavior inside of elements
650 allowing paragraph tags clarified: only inline content delimeted by
651 double newlines (not block elements) are paragraphed.
652 - Buggy treatment of end tags of elements that have required attributes
653 fixed (does not manifest on default tag-set)
654 - Spurious internal content reorganization error suppressed
655 - HTMLDefinition->addElement now returns a reference to the created
656 element object, as implied by the documentation
657 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
658 - Fix a theoretical class of infinite loops from DirectLex reported
659 by Nate Abele
660 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
661 in PHP 5.1
662 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
663 HTMLDefinition errors, this may indicate problems with error-collecting
664 facilities in PHP 5
665 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
666 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
667 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
668 to better communicate its purpose
669 . Error unit tests can now specify the expectation of no errors. Future
670 iterations of the harness will be extremely strict about what errors
671 are allowed
672 . Extend Injector hooks to allow for more powerful injector routines
673 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
674 method
675 . Doxygen configuration file updated, with minor improvements
676 . Test runner now checks for similarly named files in conf/ directory too.
677 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
678 outputted
679 . Maintenance script for generating PH5P patch added, original PH5P source
680 file also added under version control
681 . Full unit test runner script title made more descriptive with PHP version
682 . Updated INSTALL file to state that 4.3.7 is the earliest version we
683 are actively testing
685 2.1.2, released 2007-09-03
686 ! Implemented Object module for trusted users
687 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
688 this to your code:
689 require_once 'HTMLPurifier/Lexer/PH5P.php';
690 $config->set('Core', 'LexerImpl', 'PH5P');
691 Note that this Lexer introduces some classes not in the HTMLPurifier
692 namespace. Also, this is PHP5 only.
693 ! CSS property border-spacing implemented
694 - Fix non-visible parsing error in DirectLex with empty tags that have
695 slashes inside attribute values.
696 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
697 accepted as valid CSS. Usually non-visible, because this styling is the
698 default for tables in most browsers. Thanks Brett Zamir for pointing
699 this out.
700 - Fix validation errors in configuration form
701 - Hammer out a bunch of edge-case bugs in the standalone distribution
702 - Inclusion reflection removed from URISchemeRegistry; you must manually
703 include any new schema files you wish to use
704 - Numerous typo fixes in documentation thanks to Brett Zamir
705 . Unit test refactoring for one logical test per test function
706 . Config and context parameters in ComplexHarness deprecated: instead, edit
707 the $config and $context member variables
708 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
709 really make a difference, but is good for completeness sake
710 . merge-library.php script refactored for greater code reusability and
711 PHP4 compatibility
713 2.1.1, released 2007-08-04
714 - Fix show-stopper bug in %URI.MakeAbsolute functionality
715 - Fix PHP4 syntax error in standalone version
716 . Add prefix directory to include path for standalone, this prevents
717 other installations from clobbering the standalone's URI schemes
718 . Single test methods can be invoked by prefixing with __only
720 2.1.0, released 2007-08-02
721 # flush-htmldefinition-cache.php superseded in favor of a generic
722 flush-definition-cache.php script, you can clear a specific cache
723 by passing its name as a parameter to the script
724 ! Phorum mod implemented for HTML Purifier
725 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
726 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
727 for PHP4 (DirectLex).
728 ! Standalone file now available, which greatly reduces the amount of
729 includes (although there are still a few files that reside in the
730 standalone folder)
731 ! Relative URIs can now be transformed into their absolute equivalents
732 using %URI.Base and %URI.MakeAbsolute
733 ! Ruby implemented for XHTML 1.1

744 . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
745 for output cache invalidation
746 . ConfigForm printer now can retrieve CSS and JS files as strings, in
747 case HTML Purifier's directory is not publically accessible
748 . Introduce new text/itext configuration directive values: these represent
749 longer strings that would be more appropriately edited with a textarea
750 . Allow newlines to act as separators for lists, hashes, lookups and
751 %HTML.Allowed
752 . ConfigForm generates textareas instead of text inputs for lists, hashes,
753 lookups, text and itext fields
754 . Hidden element content removal genericized: %Core.HiddenElements can
755 be used to customize this behavior, by default <script> and <style> are
756 hidden
757 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
758 . Custom ChildDef added to default include list
759 . URIScheme reflection improved: will not attempt to include file if class
760 already exists. May clobber autoload, so I need to keep an eye on it
761 . ConfigSchema heavily optimized, will only collect information and validate
762 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
763 . AttrDef_URI unit tests and implementation refactored
764 . benchmarks/ directory now protected from public view with .htaccess file;
765 run the tests via command line
766 . URI scheme is munged off if there is no authority and the scheme is the
767 default one
768 . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
769 . Interface for URIScheme changed
770 . Generic URI object to hold components of URI added, most systems involved
771 in URI validation have been migrated to use it
772 . Custom filtering for URIs factored out to URIDefinition interface for
773 maximum extensibility
775 2.0.1, released 2007-06-27
776 ! Tag auto-closing now based on a ChildDef heuristic rather than a
777 manually set auto_close array; some behavior may change
778 ! Experimental AutoFormat functionality added: auto-paragraph and
779 linkify your HTML input by setting %AutoFormat.AutoParagraph and
780 %AutoFormat.Linkify to true
781 ! Newlines normalized internally, and then converted back to the
782 value of PHP_EOL. If this is not desired, set your newline format
783 using %Output.Newline.
784 ! Beta error collection, messages are implemented for the most generic
785 cases involving Lexing or Strategies
786 - Clean up special case code for <script> tags
787 - Reorder includes for DefinitionCache decorators, fixes a possible
788 missing class error
789 - Fixed bug where manually modified definitions were not saved via cache

791 - Configuration objects with different serials do not clobber each
792 others when revision numbers are unequal
793 - Improve Serializer DefinitionCache directory permissions checks
794 - DefinitionCache no longer throws errors when it encounters old
795 serial files that do not conform to the current style

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

855 in tags now.
856 - Bug resulting from tag transforms to non-allowed elements fixed
857 - ChildDef_Custom's regex generation has been improved, removing several
858 false positives
859 . Unit test for ElementDef created, ElementDef behavior modified to
860 be more flexible

881 + clear in br
882 + align in caption, table, img and hr
883 + type in ul, ol and li
884 ! DirectLex now preserves text in which a < bracket is followed by
885 a non-alphanumeric character. This means that certain emoticons
886 are now preserved.
887 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
888 images will hang around with an empty src
889 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
890 to enable
891 ! CSS property white-space now allows nowrap (supported in all modern
892 browsers) but not others (which have spotty browser implementations)

922 %Attr.IDBlacklistRegexp
923 - Error messages are emitted when you attempt to "allow" elements or
924 attributes that HTML Purifier does not support
925 - Fix segfault in unit test. The problem is not very reproduceable and
926 I don't know what causes it, but a six line patch fixed it.
928 1.5.0, released 2007-03-23
929 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It

932 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
933 I am loathe to release beta quality APIs, but this is exactly that;
934 don't use the internal interfaces if you're not willing to do migration
935 later on.
936 - Allow 'x' subtag in language codes
937 - Fixed buggy chameleon-support for ins and del
938 . Added support for IDREF attributes (i.e. for)
939 . Renamed HTMLPurifier_AttrDef_Class to HTMLPurifier_AttrDef_Nmtokens
940 . Removed context variable ParentType, replaced with IsInline, which
941 is false when you're not inline and an integer of the parent that
942 caused you to become inline when you are (so possibly zero)
943 . Removed ElementDef->type in favor of ElementDef->descendants_are_inline
944 and HTMLDefinition->content_sets
945 . StrictBlockquote now reports what elements its supposed to allow,
946 rather than what it does allow
947 . Removed HTMLDefinition->info_flow_elements in favor of
948 HTMLDefinition->content_sets['Flow']
949 . Removed redundant "exclusionary" definitions from DTD roster
950 . StrictBlockquote now requires a construction parameter as if it
951 were an Required ChildDef, this is the "real" set of allowed elements
952 . AttrDef partitioned into HTML, CSS and URI segments
953 . Modify Youtube filter regexp to be multiline
954 . Require both PHP5 and DOM extension in order to use DOMLex, fixes
955 some edge cases where a DOMDocument class exists in a PHP4 environment
956 due to DOM XML extension.
