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

506 . UTF-8 encoding check optimization as suggested by Diego
507 . HTMLPurifier_Error removed in favor of exceptions
508 . More copy() function removed; should use clone instead
509 . More extensive unit tests for HTMLDefinition
510 . assertPurification moved to central harness
511 . HTMLPurifier_Generator accepts $config and $context parameters during
512 instantiation, not runtime
513 . Double-quotes outside of attribute values are now unescaped
515 3.1.0rc1, released 2008-04-22
516 # Autoload support added. Internal require_once's removed in favor of an
517 explicit require list or autoloading. To use HTML Purifier,
518 you must now either use HTMLPurifier.auto.php
519 or HTMLPurifier.includes.php; setting the include path and including
520 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
521 as well to register our autoload handler (or modify your autoload function
522 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
523 HTMLPurifier.safe-includes.php for a less performance friendly but more
524 user-friendly library load.
525 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
526 information is stored in the ConfigSchema directory, and the
527 maintenance/generate-schema-cache.php generates the schema.ser file, which
528 is now instantiated. Support for userland schema changes coming soon!
529 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
530 alias; to get rid of these errors just modify your configuration to use
531 the new directive name.
532 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
533 enabled using %Filter.$filter_name or by setting your own filters using
534 %Filter.Custom
535 # Directive-level safety properties superceded in favor of module-level
536 safety. Internal method HTMLModule->addElement() has changed, although
537 the externally visible HTMLDefinition->addElement has *not* changed.
538 ! Extra utility classes for testing and non-library operations can
539 be found in extras/. Specifically, these are FSTools and ConfigDoc.
540 You may find a use for these in your own project, but right now they
541 are highly experimental and volatile.
542 ! Integration with PHPT allows for automated smoketests
543 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
544 by Chris. You can enable them with %HTML.Proprietary if your client
545 demands them.
546 ! Support for !important CSS cascade modifier. By default, this will be stripped
547 from CSS, but you can enable it using %CSS.AllowImportant
548 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
549 to true to use them.
550 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
551 Developer error (not enduser error) can cause these to be triggered.
552 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
553 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
554 mucking around with HTMLPurifier_CSSDefinition
555 ! ConfigDoc output has been enhanced with version and deprecation info.
556 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
557 - Autoclose now operates iteratively, i.e. <span><span><div> now has
558 both span tags closed.
559 - Various HTMLPurifier_Config convenience functions now accept another parameter
560 $schema which defines what HTMLPurifier_ConfigSchema to use besides the
561 global default.
562 - Fix bug with trusted script handling in libxml versions later than 2.6.28.
563 - Fix bug in ExtractStyleBlocks with comments in style tags
564 - Fix bug in comment parsing for DirectLex
565 - Flush output now displayed when in command line mode for unit tester
566 - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax
567 - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times
568 on the same element without emitting errors.
569 - Fixed fatal error in PH5P lexer with invalid tag names

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

582 . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
583 . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
584 . New --php=php flag added, allows PHP executable to be specified (command
585 line only!)
586 . htmlpurifier_add_test() preferred method to translate test files in to
587 classes, because it handles PHPT files too.
588 . Debugger class is deprecated and will be removed soon.
589 . Command line argument parsing for testing scripts revamped, now --opt value
590 format is supported.
591 . Smoketests now cleanup after magic quotes
592 . Generator now can output comments (however, comments are still stripped
593 from HTML Purifier output)
594 . HTMLPurifier_ConfigSchema->validate() deprecated in favor of
595 HTMLPurifier_VarParser->parse()
596 . Integers auto-cast into float type by VarParser.
597 . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
598 during cache generation
599 . Reordered script calls in maintenance/flush.php
600 . Command line scripts now honor exit codes
601 . When --flush fails in unit testers, abort tests and print message
602 . Improved documentation in docs/dev-flush.html about the maintenance scripts
603 . copy() methods removed in favor of clone keyword
605 3.0.0, released 2008-01-06
606 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
607 until PHP 4 is completely deprecated, but no new features will be added
608 to it.
609 + Visibility declarations added
610 + Constructor methods renamed to __construct()
611 + PHP4 reference cruft removed (in progress)
612 ! CSS properties are now case-insensitive

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

633 2.1.3, released 2007-11-05
634 ! tests/multitest.php allows you to test multiple versions by running
635 tests/index.php through multiple interpreters using `phpv` shell
636 script (you must provide this script!)
637 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
638 on some systems.
639 - Injector algorithm further refined: off-by-one error regarding skip
640 counts for dormant injectors fixed
641 - Corrective blockquote definition now enabled for HTML 4.01 Strict
642 - Fatal error when <img> tag (or any other element with required attributes)
643 has 'id' attribute fixed, thanks NykO18 for reporting
644 - Fix warning emitted when a non-supported URI scheme is passed to the
645 MakeAbsolute URIFilter, thanks NykO18 (again)
646 - Further refine AutoParagraph injector. Behavior inside of elements
647 allowing paragraph tags clarified: only inline content delimeted by
648 double newlines (not block elements) are paragraphed.
649 - Buggy treatment of end tags of elements that have required attributes
650 fixed (does not manifest on default tag-set)
651 - Spurious internal content reorganization error suppressed
652 - HTMLDefinition->addElement now returns a reference to the created
653 element object, as implied by the documentation
654 - Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
655 - Fix a theoretical class of infinite loops from DirectLex reported
656 by Nate Abele
657 - Work around unnecessary DOMElement type-cast in PH5P that caused errors
658 in PHP 5.1
659 - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
660 HTMLDefinition errors, this may indicate problems with error-collecting
661 facilities in PHP 5
662 - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
663 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
664 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
665 to better communicate its purpose
666 . Error unit tests can now specify the expectation of no errors. Future
667 iterations of the harness will be extremely strict about what errors
668 are allowed
669 . Extend Injector hooks to allow for more powerful injector routines
670 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
671 method
672 . Doxygen configuration file updated, with minor improvements
673 . Test runner now checks for similarly named files in conf/ directory too.
674 . Minor cosmetic change to flush-definition-cache.php: trailing newline is
675 outputted
676 . Maintenance script for generating PH5P patch added, original PH5P source
677 file also added under version control
678 . Full unit test runner script title made more descriptive with PHP version
679 . Updated INSTALL file to state that 4.3.7 is the earliest version we
680 are actively testing
682 2.1.2, released 2007-09-03
683 ! Implemented Object module for trusted users
684 ! Implemented experimental HTML5 parsing mode using PH5P. To use, add
685 this to your code:
686 require_once 'HTMLPurifier/Lexer/PH5P.php';
687 $config->set('Core', 'LexerImpl', 'PH5P');
688 Note that this Lexer introduces some classes not in the HTMLPurifier
689 namespace. Also, this is PHP5 only.
690 ! CSS property border-spacing implemented
691 - Fix non-visible parsing error in DirectLex with empty tags that have
692 slashes inside attribute values.
693 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
694 accepted as valid CSS. Usually non-visible, because this styling is the
695 default for tables in most browsers. Thanks Brett Zamir for pointing
696 this out.
697 - Fix validation errors in configuration form
698 - Hammer out a bunch of edge-case bugs in the standalone distribution
699 - Inclusion reflection removed from URISchemeRegistry; you must manually
700 include any new schema files you wish to use
701 - Numerous typo fixes in documentation thanks to Brett Zamir
702 . Unit test refactoring for one logical test per test function
703 . Config and context parameters in ComplexHarness deprecated: instead, edit
704 the $config and $context member variables
705 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
706 really make a difference, but is good for completeness sake
707 . merge-library.php script refactored for greater code reusability and
708 PHP4 compatibility
710 2.1.1, released 2007-08-04
711 - Fix show-stopper bug in %URI.MakeAbsolute functionality
712 - Fix PHP4 syntax error in standalone version
713 . Add prefix directory to include path for standalone, this prevents
714 other installations from clobbering the standalone's URI schemes
715 . Single test methods can be invoked by prefixing with __only
717 2.1.0, released 2007-08-02
718 # flush-htmldefinition-cache.php superseded in favor of a generic
719 flush-definition-cache.php script, you can clear a specific cache
720 by passing its name as a parameter to the script
721 ! Phorum mod implemented for HTML Purifier
722 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
723 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
724 for PHP4 (DirectLex).
725 ! Standalone file now available, which greatly reduces the amount of
726 includes (although there are still a few files that reside in the
727 standalone folder)
728 ! Relative URIs can now be transformed into their absolute equivalents
729 using %URI.Base and %URI.MakeAbsolute

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

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

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

850 honor error_reporting is used
851 - StrictBlockquote child definition refrains from wrapping whitespace
852 in tags now.
853 - Bug resulting from tag transforms to non-allowed elements fixed
854 - ChildDef_Custom's regex generation has been improved, removing several
855 false positives
856 . Unit test for ElementDef created, ElementDef behavior modified to
857 be more flexible
858 . Added convenience functions for HTMLModule constructors

876 + size and noshade in hr
877 + nowrap in td
878 + clear in br
879 + align in caption, table, img and hr
880 + type in ul, ol and li
881 ! DirectLex now preserves text in which a < bracket is followed by
882 a non-alphanumeric character. This means that certain emoticons
883 are now preserved.
884 ! %Core.RemoveInvalidImg is now operational, when set to false invalid
885 images will hang around with an empty src
886 ! target attribute in a tag supported, use %Attr.AllowedFrameTargets
887 to enable
888 ! CSS property white-space now allows nowrap (supported in all modern
889 browsers) but not others (which have spotty browser implementations)
890 ! XHTML 1.1 mode now sort-of works without any fatal errors, and

901 . Basic.php script modified to work out of the box
902 . Refactor AttrTransform classes to reduce duplication
903 . AttrTransform_TextAlign axed in favor of a more general
904 AttrTransform_EnumToCSS, refer to HTMLModule/TransformToStrict.php to
905 see how the new equivalent is implemented
906 . Unit tests now use exclusively assertIdentical
908 1.6.0, released 2007-04-01

910 + bgcolor in td, th, tr and table
911 + border in img
912 + name in a and img
913 + width in td, th and hr

919 %Attr.IDBlacklistRegexp
920 - Error messages are emitted when you attempt to "allow" elements or
921 attributes that HTML Purifier does not support
922 - Fix segfault in unit test. The problem is not very reproduceable and
923 I don't know what causes it, but a six line patch fixed it.
925 1.5.0, released 2007-03-23
926 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
