2 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
4 = KEY ====================
10 ==========================
12 4.9.0, unknown release date
13 ! %URI.DefaultScheme can now be set to null, in which case
14 all relative paths are removed.
15 ! New CSS properties: min-width, max-width, min-height, max-height (#94)
16 - When idn_to_ascii is defined, we might accept malformed
17 hostnames. Apply validation to the result in such cases.
18 - Close directory when done in Serializer DefinitionCache (#100)
19 - Deleted some asserts to avoid linters from choking (#97)
20 - Rework Serializer cache behavior to avoid chmod'ing if possible (#32)
21 - Embedded semicolons in strings in CSS are now handled correctly!
23 4.8.0, released 2016-07-16
24 # By default, when a link has a target attribute associated
25 with it, we now also add rel="noreferrer" in order to
26 prevent the new window from being able to overwrite
27 the original frame. To disable this protection,
28 set %HTML.TargetNoreferrer to FALSE.
29 ! Full PHP 7 compatibility, the test suite is ALL GO.
30 ! %CSS.AllowDuplicates permits duplicate CSS properties.
31 ! Support for 'tel' URIs.
32 ! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
33 The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
35 ! %Attr.ID.HTML5 turns on HTML5-style ID handling.
36 - alt truncation could result in malformed UTF-8 sequence. Don't
37 truncate. Thanks Brandon Farber for reporting.
38 - Linkify regex is smarter, based off of Gruber's regex.
39 - IDNA supported natively on PHP 5.3 and later.
40 - Non all-numeric top-level names (e.g., foo.1f, 1f) are now
42 - Minor bounds error fix to squash a PHP 7 notice.
43 - Support non-/tmp temporary directories for data:// validation
44 - Give a better error message when a user attempts to allow
45 ul/ol without allowing li.
46 - On some versions of PHP, the Serializer DefinitionCache could
47 infinite loop when the directory exists but is not listable. (#49)
48 - Don't match for <body> inside comments with
49 %Core.ConvertDocumentToFragment. (#67)
50 - SafeObject is now less case sensitive. (#57)
51 - AutoFormat.RemoveEmpty.Predicate now correctly renders in
54 4.7.0, released 2015-08-04
55 # opacity is now considered a "tricky" CSS property rather than a
57 ! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
58 an element should be considered "empty" (maybe preserve if it
59 has attributes), and modify iframe support so that the iframe
60 is removed if it is missing a src attribute. Thanks meeva for
62 - Don't truncate upon encountering </div> when using DOMLex. Thanks
63 Myrto Christina for finally convincing me to fix this.
64 - Update YouTube filter for new code.
65 - Fix parsing of rgb() values with spaces in them for 'border'
67 - Don't remove foo="" attributes if foo is a boolean attribute. Thanks
70 4.6.0, released 2013-11-30
71 # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
72 Please update any verification scripts you may have.
73 # URI parsing algorithm was made more strict, so only prefixes which
74 looks like schemes will actually be schemes. Thanks
75 Michael Gusev <mgusev@sugarcrm.com> for fixing.
76 # %Core.EscapeInvalidChildren is no longer supported, and no longer does
78 ! New directive %Core.AllowHostnameUnderscore which allows underscores
80 - Eliminate quadratic behavior in DOMLex by using a proper queue.
81 Thanks Ole Laursen for noticing this.
82 - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
83 behavior in the rest of the purificaiton pipeline. Thanks Chedburn
84 Networks for sponsoring this work.
85 - Made Linkify URL parser a bit less permissive, so that non-breaking
86 spaces and commas are not included as part of URL. Thanks nAS for fixing.
87 - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
88 David Hirtz for reporting.
89 - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
92 4.5.0, released 2013-02-17
93 # Fix bug where stacked attribute transforms clobber each other;
94 this also means it's no longer possible to override attribute
95 transforms in later modules. No internal code was using this
96 but this may break some clients.
97 # We now use SHA-1 to identify cached definitions, instead of MD5.
98 ! Support display:inline-block
99 ! Support for more white-space CSS values.
100 ! Permit underscores in font families
101 ! Support for page-break-* CSS3 properties when proprietary properties
103 ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
104 SGML excludes checking. If HTML Purifier is removing too much text
105 and you don't care about full standards compliance, try setting this to
107 - Use prepend for SPL autoloading on PHP 5.3 and later.
108 - Fix bug with nofollow transform when pre-existing rel exists.
109 - Fix bug where background:url() always gets lower-cased
110 (but not background-image:url())
111 - Fix bug with non lower-case color names in HTML
112 - Fix bug where data URI validation doesn't remove temporary files.
113 Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
114 - Don't remove certain empty tags on RemoveEmpty.
116 4.4.0, released 2012-01-18
117 # Removed PEARSax3 handler.
118 # URI.Munge now munges URIs inside the same host that go from https
119 to http. Reported by Neike Taika-Tessaro.
120 # Core.EscapeNonASCIICharacters now always transforms entities to
121 entities, even if target encoding is UTF-8.
122 # Tighten up selector validation in ExtractStyleBlocks.
123 Non-syntactically valid selectors are now rejected, along with
124 some of the more obscure ones such as attribute selectors, the
125 :lang pseudoselector, and anything not in CSS2.1. Furthermore,
126 ID and class selectors now work properly with the relevant
127 configuration attributes. Also, mute errors when parsing CSS
128 with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
129 ! Added support for 'scope' attribute on tables.
130 ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
131 ! Properly handle sub-lists directly nested inside of lists in
132 a standards compliant way, by moving them into the preceding <li>
133 ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
134 limited allowed comments in untrusted situations.
135 ! Implement iframes, and allow them to be used in untrusted mode with
136 %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
137 <brad.froehle@gmail.com> for submitting an initial version of the patch.
138 ! The Forms module now works properly for transitional doctypes.
139 ! Added support for internationalized domain names. You need the PEAR
140 Net_IDNA2 module to be in your path; if it is installed, ensure the
141 class can be loaded and then set %Core.EnableIDNA to true.
142 - Color keywords are now case insensitive. Thanks Yzmir Ramirez
143 <yramirez-htmlpurifier@adicio.com> for reporting.
144 - Explicitly initialize anonModule variable to null.
145 - Do not duplicate nofollow if already present. Thanks 178
147 - Do not add nofollow if hostname matches our current host. Thanks 178
148 for reporting, and Neike Taika-Tessaro for helping diagnose.
149 - Do not unset parser variable; this fixes intermittent serialization
150 problems. Thanks Neike Taika-Tessaro for reporting, bill
151 <10010tiger@gmail.com> for diagnosing.
152 - Fix iconv truncation bug, where non-UTF-8 target encodings see
153 output truncated after around 8000 characters. Thanks Jörg Ludwig
154 <joerg.ludwig@iserv.eu> for reporting.
155 - Fix broken table content model for XHTML1.1 (and also earlier
156 versions, although the W3C validator doesn't catch those violations).
157 Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
159 4.3.0, released 2011-03-27
160 # Fixed broken caching of customized raw definitions, but requires an
161 API change. The old API still works but will emit a warning,
162 see http://htmlpurifier.org/docs/enduser-customize.html#optimized
163 for how to upgrade your code.
164 # Protect against Internet Explorer innerHTML behavior by specially
165 treating attributes with backticks but no angled brackets, quotes or
166 spaces. This constitutes a slight semantic change, which can be
167 reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
169 # Protect against cssText/innerHTML by restricting allowed characters
170 used in fonts further than mandated by the specification and encoding
171 some extra special characters in URLs. Reported by Neike
172 Taika-Tessaro and Mario Heiderich.
173 ! Added %HTML.Nofollow to add rel="nofollow" to external links.
174 ! More types of SPL autoloaders allowed on later versions of PHP.
175 ! Implementations for position, top, left, right, bottom, z-index
176 when %CSS.Trusted is on.
177 ! Add %Cache.SerializerPermissions option for custom serializer
178 directory/file permissions
179 ! Fix longstanding bug in Flash support for non-IE browsers, and
180 allow more wmode attributes.
181 ! Add %CSS.AllowedFonts to restrict permissible font names.
182 - Switch to an iterative traversal of the DOM, which prevents us
183 from running out of stack space for deeply nested documents.
184 Thanks Maxim Krizhanovsky for contributing a patch.
185 - Make removal of conditional IE comments ungreedy; thanks Bernd
187 - Escape CDATA before removing Internet Explorer comments.
188 - Fix removal of id attributes under certain conditions by ensuring
189 armor attributes are preserved when recreating tags.
190 - Check if schema.ser was corrupted.
191 - Check if zend.ze1_compatibility_mode is on, and error out if it is.
192 This safety check is only done for HTMLPurifier.auto.php; if you
193 are using standalone or the specialized includes files, you're
194 expected to know what you're doing.
195 - Stop repeatedly writing the cache file after I'm done customizing a
196 raw definition. Reported by ajh.
197 - Switch to using require_once in the Bootstrap to work around bad
198 interaction with Zend Debugger and APC. Reported by Antonio Parraga.
199 - Fix URI handling when hostname is missing but scheme is present.
200 Reported by Neike Taika-Tessaro.
201 - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
203 - Fix harmless notice from indexing into empty string. Thanks Matthijs
204 Kooijman <matthijs@stdin.nl> for reporting.
205 - Don't autoclose no parent elements are able to support the element
206 that triggered the autoclose. In particular fixes strange behavior
207 of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
208 Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
210 4.2.0, released 2010-09-15
211 ! Added %Core.RemoveProcessingInstructions, which lets you remove
212 <? ... ?> statements.
213 ! Added %URI.DisableResources functionality; the directive originally
214 did nothing. Thanks David Rothstein for reporting.
215 ! Add documentation about configuration directive types.
216 ! Add %CSS.ForbiddenProperties configuration directive.
217 ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
218 to utilize full-screen mode.
219 ! Add optional support for the <code>file</code> URI scheme, enable
220 by explicitly setting %URI.AllowedSchemes.
221 ! Add %Core.NormalizeNewlines options to allow turning off newline
223 - Fix improper handling of Internet Explorer conditional comments
224 by parser. Thanks zmonteca for reporting.
225 - Fix missing attributes bug when running on Mac Snow Leopard and APC.
226 Thanks sidepodcast for the fix.
227 - Warn if an element is allowed, but an attribute it requires is
230 4.1.1, released 2010-05-31
231 - Fix undefined index warnings in maintenance scripts.
232 - Fix bug in DirectLex for parsing elements with a single attribute
234 - Rewrite CSS output logic for font-family and url(). Thanks Mario
235 Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
236 Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
237 - Emit an error for CollectErrors if a body is extracted
238 - Fix bug where in background-position for center keyword handling.
239 - Fix infinite loop when a wrapper element is inserted in a context
240 where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
241 - Remove +x bit and shebang from index.php; only supported mode is to
242 explicitly call it with php.
243 - Make test script less chatty when log_errors is on.
245 4.1.0, released 2010-04-26
246 ! Support proprietary height attribute on table element
247 ! Support YouTube slideshows that contain /cp/ in their URL.
248 ! Support for data: URI scheme; not enabled by default, add it using
250 ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
251 ! Support for Internet Explorer compatibility with %HTML.SafeObject
252 using %Output.FlashCompat.
253 ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
254 - Always quote the insides of url(...) in CSS.
256 4.0.0, released 2009-07-07
257 # APIs for ConfigSchema subsystem have substantially changed. See
258 docs/dev-config-bcbreaks.txt for details; in essence, anything that
259 had both namespace and directive now have a single unified key.
260 # Some configuration directives were renamed, specifically:
261 %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
262 %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
263 %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
264 %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
265 As usual, the old directive names will still work, but will throw E_NOTICE
267 # The allowed values for class have been relaxed to allow all of CDATA for
268 doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
269 %Attr.ClassUseCDATA to false.
270 # Instead of appending the content model to an old content model, a blank
271 element will replace the old content model. You can use #SUPER to get
272 the old content model.
273 ! More robust support for name="" and id=""
274 ! HTMLPurifier_Config::inherit($config) allows you to inherit one
275 configuration, and have changes to that configuration be propagated
276 to all of its children.
277 ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
278 the name attribute when set. Use with care. Thanks Ian Cook for
280 ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
281 tags that contain non-breaking spaces as well other whitespace. You
282 can also modify which tags should have maintained with
283 %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
284 ! Implement %Attr.AllowedClasses, which allows administrators to restrict
285 classes users can use to a specified finite set of classes, and
286 %Attr.ForbiddenClasses, which is the logical inverse.
287 ! You can now maintain your own configuration schema directories by
288 creating a config-schema.php file or passing an extra argument. Check
289 docs/dev-config-schema.html for more details.
290 ! Added HTMLPurifier_Config->serialize() method, which lets you save away
291 your configuration in a compact serial file, which you can unserialize
292 and use directly without having to go through the overhead of setup.
293 - Fix bug where URIDefinition would not get cleared if it's directives got
295 - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
296 - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
297 - Make %URI.Munge not apply to links that have the same host as your host.
298 - Prevent stray </body> tag from truncating output, if a second </body>
300 . Created script maintenance/rename-config.php for renaming a configuration
301 directive while maintaining its alias. This script does not change source code.
302 . Implement namespace locking for definition construction, to prevent
303 bugs where a directive is used for definition construction but is not
304 used to construct the cache hash.
306 3.3.0, released 2009-02-16
307 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
308 ! Implement generic property list classess
309 - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
310 does not do the "right thing" with characters not supported in the output
312 - Spellcheck UTF-8: The Secret To Character Encoding
313 - Fix improper removal of the contents of elements with only whitespace. Thanks
314 Eric Wald for reporting.
315 - Fix broken test suite in versions of PHP without spl_autoload_register()
316 - Fix degenerate case with YouTube filter involving double hyphens.
317 Thanks Pierre Attar for reporting.
318 - Fix YouTube rendering problem on certain versions of Firefox.
319 - Fix CSSDefinition Printer problems with decorators
320 - Add text parameter to unit tests, forces text output
321 . Add verbose mode to command line test runner, use (--verbose)
322 . Turn on unit tests for UnitConverter
323 . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
324 . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
326 . Removed trailing whitespace from all text files, see
327 remote-trailing-whitespace.php maintenance script.
328 . Convert configuration to use property list backend.
330 3.2.0, released 2008-10-31
331 # Using %Core.CollectErrors forces line number/column tracking on, whereas
332 previously you could theoretically turn it off.
333 # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
334 use handleEnd() instead.
335 ! %Output.AttrSort for when you need your attributes in alphabetical order to
336 deal with a bug in FCKEditor. Requested by frank farmer.
337 ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
338 ! Proper support for name attribute. It is now allowed and equivalent to the id
339 attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
340 is heavy (for all doctypes).
341 ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
342 use on hand-written HTML.
343 ! Add error-cases for unsupported elements in MakeWellFormed. This enables
344 the strategy to be used, standalone, on untrusted input.
345 ! %Core.AggressivelyFixLt is on by default. This causes more sensible
346 processing of left angled brackets in smileys and other whatnot.
347 ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
348 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
349 the --only-phpt parameter, although for backwards-compatibility the flag
351 ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
352 Users who are not performing inbound filtering, this may seem a little
353 useless, but as a bonus, the test suite and handling of edge cases is also
355 ! Experimental implementation of forms for %HTML.Trusted
356 ! Track column numbers when maintain line numbers is on
357 ! Proprietary 'background' attribute on table-related elements converted into
358 corresponding CSS. Thanks Fusemail for sponsoring this feature!
359 ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
361 ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
362 time of operation varies slightly from notifyEnd() as *all* end tokens are
363 processed by the injector before they are subject to the well-formedness rules.
364 ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
365 basename of image when not present.
366 ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
367 - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
368 the other involving an undefined $is_folder error.
369 - Throw error when %Core.Encoding is set to a spurious value. Previously,
370 this errored silently and returned false.
371 - Redirected stderr to stdout for flush error output.
372 - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
374 - Do not re-munge URL if the output URL has the same host as the input URL.
376 - Fix error in documentation regarding %Filter.ExtractStyleBlocks
377 - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
378 - Fix bug with inline elements in blockquotes conflicting with strict doctype
379 - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
380 - Fix bug where dots and double-dots in absolute URLs without hostname were
381 not collapsed by URIFilter_MakeAbsolute.
382 - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
383 by reordering their addition.
384 - Will now throw exception on many error conditions during lexer creation; also
385 throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
387 - Detect if domxml extension is loaded, and use DirectLEx accordingly.
388 - Improve handling of big numbers with floating point arithmetic in UnitConverter.
389 Reported by David Morton.
390 . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
391 for more interesting filter-backtracking
392 . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
393 index to reprocess tokens.
394 . StringHashParser now allows for multiline sections with "empty" content;
395 previously the section would remain undefined.
396 . Added --quick option to multitest.php, which tests only the most recent
397 release for each series.
398 . Added --distro option to multitest.php, which accepts either 'normal' or
399 'standalone'. This supercedes --exclude-normal and --exclude-standalone
401 3.1.1, released 2008-06-19
402 # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
403 In order to enable this again, please set %URI.MungeResources to true.
404 ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
405 and height/width HTML with %HTML.MaxImgLength.
406 ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
407 for sponsoring this feature. Check out the corresponding documentation
408 for details. (Att Nightly testers: The API for this feature changed before
409 the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
410 %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
411 ! Implemented post URI filtering. Set member variable $post to true to set
413 ! Allow modules to define injectors via $info_injector. Injectors are
414 automatically disabled if injector's needed elements are not found.
415 ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
416 Thanks Chris for sponsoring. If you've been using ad hoc code from the
417 forums, PLEASE use this instead.
418 ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
419 embedded, tag name, attribute name, CSS property name). See %URI.Munge
420 for more details. Requested by Jochem Blok.
421 - Disable percent height/width attributes for img.
422 - AttrValidator operations are now atomic; updates to attributes are not
423 manifest in token until end of operations. This prevents naughty internal
424 code from directly modifying CurrentToken when they're not supposed to.
425 This semantics change was requested by frank farmer.
426 - Percent encoding checks enabled for URI query and fragment
427 - Fix stray backslashes in font-family; CSS Unicode character escapes are
428 now properly resolved (although *only* in font-family). Thanks Takeshi Terada
430 - Improve parseCDATA algorithm to take into account newline normalization
431 - Account for browser confusion between Yen character and backslash in
432 Shift_JIS encoding. This fix generalizes to any other encoding which is not
433 a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
434 - Fix missing configuration parameter in Generator calls. Thanks vs for the
436 - Improved adherence to Unicode by checking for non-character codepoints.
437 Thanks Geoffrey Sneddon for reporting. This may result in degraded
438 performance for extremely large inputs.
439 - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
441 . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
442 handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
444 . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
445 to __construct($min, $max). __construct(true) is equivalent to
447 . Added HTMLPurifier_AttrDef_Switch class
448 . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
449 up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
450 get this called with the configuration object. All modules now
451 use this rather than __construct(), although legacy code using constructors
452 will still work--the new format, however, lets modules access the
453 configuration object for HTML namespace dependant tweaks.
454 . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
455 . ConfigSchema data-structure heavily optimized; on average it uses a third
456 the memory it did previously. The interface has changed accordingly,
457 consult changes to HTMLPurifier_Config for details.
458 . Variable parsing types now are magic integers instead of strings
459 . Added benchmark for ConfigSchema
460 . HTMLPurifier_Generator requires $config and $context parameters. If you
461 don't know what they should be, use HTMLPurifier_Config::createDefault()
462 and new HTMLPurifier_Context().
463 . Printers now properly distinguish between output configuration, and
464 target configuration. This is not applicable to scripts using
465 the Printers for HTML Purifier related tasks.
466 . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
467 fatal errors will ensue.
468 . URIFilter->prepare can return false in order to abort loading of the filter
469 . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
470 an external resource.
471 . %URI.Munge functionality factored out into a post-filter class.
472 . Added CurrentCSSProperty context variable during CSS validation
474 3.1.0, released 2008-05-18
475 # Unnecessary references to objects (vestiges of PHP4) removed from method
476 signatures. The following methods do not need references when assigning from
477 them and will result in E_STRICT errors if you try:

488 # %HTML.ForbiddenAttributes requires attribute declarations to be in the
489 form of tag@attr, NOT tag.attr (which will throw an error and won't do
490 anything). This is for forwards compatibility with XML; you'd do best
491 to migrate an %HTML.AllowedAttributes directives to this syntax too.
492 ! Allow index to be false for config from form creation
493 ! Added HTMLPurifier::VERSION constant
494 ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
495 and allows for version numbers like "3.1.0-dev".
496 ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
497 ! HTML Purifier's URI handling is a lot more robust, with much stricter
498 validation checks and better percent encoding handling. Thanks Gareth Heyes
499 for indicating security vulnerabilities from lax percent encoding.
500 ! Bootstrap autoloader deals more robustly with classes that don't exist,
501 preventing class_exists($class, true) from barfing.
502 - InterchangeBuilder now alphabetizes its lists
503 - Validation error in configdoc output fixed

508 - Fixed and revamped broken ConfigForm smoketest
509 - Bug with bool/null fields in Printer_ConfigForm fixed
510 - Bug with global forbidden attributes fixed
511 - Improved error messages for allowed and forbidden HTML elements and attributes
512 - Missing (or null) in configdoc documentation restored
513 - If DOM throws and exception during parsing with PH5P (occurs in newer versions
514 of DOM), HTML Purifier punts to DirectLex
515 - Fatal error with unserialization of ScriptRequired
516 - Created directories are now chmod'ed properly
517 - Fixed bug with fallback languages in LanguageFactory
518 - Standalone testing setup properly with autoload

526 instantiation, not runtime
527 . Double-quotes outside of attribute values are now unescaped
529 3.1.0rc1, released 2008-04-22
530 # Autoload support added. Internal require_once's removed in favor of an
531 explicit require list or autoloading. To use HTML Purifier,
532 you must now either use HTMLPurifier.auto.php
533 or HTMLPurifier.includes.php; setting the include path and including
534 HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
535 as well to register our autoload handler (or modify your autoload function
536 to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
537 HTMLPurifier.safe-includes.php for a less performance friendly but more
538 user-friendly library load.
539 # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
540 information is stored in the ConfigSchema directory, and the
541 maintenance/generate-schema-cache.php generates the schema.ser file, which
542 is now instantiated. Support for userland schema changes coming soon!
543 # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
544 alias; to get rid of these errors just modify your configuration to use
545 the new directive name.
546 # HTMLPurifier->addFilter is deprecated; built-in filters can now be
547 enabled using %Filter.$filter_name or by setting your own filters using
549 # Directive-level safety properties superceded in favor of module-level
550 safety. Internal method HTMLModule->addElement() has changed, although
551 the externally visible HTMLDefinition->addElement has *not* changed.
552 ! Extra utility classes for testing and non-library operations can
553 be found in extras/. Specifically, these are FSTools and ConfigDoc.
554 You may find a use for these in your own project, but right now they
555 are highly experimental and volatile.
556 ! Integration with PHPT allows for automated smoketests
557 ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
558 by Chris. You can enable them with %HTML.Proprietary if your client
560 ! Support for !important CSS cascade modifier. By default, this will be stripped
561 from CSS, but you can enable it using %CSS.AllowImportant
562 ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
564 ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
565 Developer error (not enduser error) can cause these to be triggered.
566 ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
567 ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
568 mucking around with HTMLPurifier_CSSDefinition
569 ! ConfigDoc output has been enhanced with version and deprecation info.
570 ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
571 - Autoclose now operates iteratively, i.e. <span><span><div> now has
572 both span tags closed.

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

612 during cache generation
613 . Reordered script calls in maintenance/flush.php
614 . Command line scripts now honor exit codes
615 . When --flush fails in unit testers, abort tests and print message
616 . Improved documentation in docs/dev-flush.html about the maintenance scripts
617 . copy() methods removed in favor of clone keyword
619 3.0.0, released 2008-01-06

631 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
632 The output CSS can also be "scoped" for a specific element, use:
633 %Filter.ExtractStyleBlocksScope
634 ! Experimental support for some proprietary CSS attributes allowed:
635 opacity (and all of the browser-specific equivalents) and scrollbar colors.
636 Enable by setting %CSS.Proprietary to true.

648 ! tests/multitest.php allows you to test multiple versions by running
649 tests/index.php through multiple interpreters using `phpv` shell
650 script (you must provide this script!)
651 - Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
653 - Injector algorithm further refined: off-by-one error regarding skip
654 counts for dormant injectors fixed
655 - Corrective blockquote definition now enabled for HTML 4.01 Strict

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

677 - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
678 . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
679 to better communicate its purpose
680 . Error unit tests can now specify the expectation of no errors. Future
681 iterations of the harness will be extremely strict about what errors
683 . Extend Injector hooks to allow for more powerful injector routines
684 . HTMLDefinition->addBlankElement created, as according to the HTMLModule
686 . Doxygen configuration file updated, with minor improvements
687 . Test runner now checks for similarly named files in conf/ directory too.

700 require_once 'HTMLPurifier/Lexer/PH5P.php';
701 $config->set('Core', 'LexerImpl', 'PH5P');
702 Note that this Lexer introduces some classes not in the HTMLPurifier
703 namespace. Also, this is PHP5 only.
704 ! CSS property border-spacing implemented
705 - Fix non-visible parsing error in DirectLex with empty tags that have
706 slashes inside attribute values.
707 - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
708 accepted as valid CSS. Usually non-visible, because this styling is the
709 default for tables in most browsers. Thanks Brett Zamir for pointing
711 - Fix validation errors in configuration form
712 - Hammer out a bunch of edge-case bugs in the standalone distribution
713 - Inclusion reflection removed from URISchemeRegistry; you must manually
714 include any new schema files you wish to use
715 - Numerous typo fixes in documentation thanks to Brett Zamir
716 . Unit test refactoring for one logical test per test function
717 . Config and context parameters in ComplexHarness deprecated: instead, edit
718 the $config and $context member variables
719 . HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
720 really make a difference, but is good for completeness sake
721 . merge-library.php script refactored for greater code reusability and
724 2.1.1, released 2007-08-04
725 - Fix show-stopper bug in %URI.MakeAbsolute functionality

727 . Add prefix directory to include path for standalone, this prevents
728 other installations from clobbering the standalone's URI schemes
729 . Single test methods can be invoked by prefixing with __only
731 2.1.0, released 2007-08-02
732 # flush-htmldefinition-cache.php superseded in favor of a generic
733 flush-definition-cache.php script, you can clear a specific cache
734 by passing its name as a parameter to the script
735 ! Phorum mod implemented for HTML Purifier
736 ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
737 trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
738 for PHP4 (DirectLex).
739 ! Standalone file now available, which greatly reduces the amount of
740 includes (although there are still a few files that reside in the
742 ! Relative URIs can now be transformed into their absolute equivalents
743 using %URI.Base and %URI.MakeAbsolute

756 for output cache invalidation
757 . ConfigForm printer now can retrieve CSS and JS files as strings, in
758 case HTML Purifier's directory is not publically accessible
759 . Introduce new text/itext configuration directive values: these represent
760 longer strings that would be more appropriately edited with a textarea
761 . Allow newlines to act as separators for lists, hashes, lookups and
763 . ConfigForm generates textareas instead of text inputs for lists, hashes,
764 lookups, text and itext fields
765 . Hidden element content removal genericized: %Core.HiddenElements can
766 be used to customize this behavior, by default <script> and <style> are
768 . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
769 . Custom ChildDef added to default include list
770 . URIScheme reflection improved: will not attempt to include file if class
771 already exists. May clobber autoload, so I need to keep an eye on it
772 . ConfigSchema heavily optimized, will only collect information and validate
773 definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
774 . AttrDef_URI unit tests and implementation refactored
775 . benchmarks/ directory now protected from public view with .htaccess file;

784 maximum extensibility
786 2.0.1, released 2007-06-27
787 ! Tag auto-closing now based on a ChildDef heuristic rather than a
788 manually set auto_close array; some behavior may change
789 ! Experimental AutoFormat functionality added: auto-paragraph and
790 linkify your HTML input by setting %AutoFormat.AutoParagraph and
791 %AutoFormat.Linkify to true
792 ! Newlines normalized internally, and then converted back to the
793 value of PHP_EOL. If this is not desired, set your newline format
794 using %Output.Newline.
795 ! Beta error collection, messages are implemented for the most generic
796 cases involving Lexing or Strategies
797 - Clean up special case code for <script> tags

817 . Interlinking in configuration documentation added using
818 Injector_PurifierLinkify
819 . Directives now keep track of aliases to themselves

823 much easier selective embedding of configuration values
824 . Doctype objects now accept public and system DTD identifiers
825 . %HTML.Doctype is now constrained by specific values, to specify a custom
826 doctype use new %HTML.CustomDoctype
827 . ConfigForm truncates long directives to keep the form small, and does
828 not re-output namespaces
830 2.0.0, released 2007-06-20
831 # Completely refactored HTMLModuleManager, decentralizing safety
833 # Transform modules changed to Tidy modules, which offer more flexibility
834 and better modularization
835 # Configuration object now finalizes itself when a read operation is
836 performed on it, ensuring that its internal state stays consistent.
837 To revert this behavior, you can set the $autoFinalize member variable
838 off, but it's not recommended.
839 # New compact syntax for AttrDef objects that can be used to instantiate
840 new objects via make()
841 # Definitions (esp. HTMLDefinition) are now cached for a significant
842 performance boost. You can disable caching by setting %Core.DefinitionCache
843 to null. You CANNOT edit raw definitions without setting the corresponding
844 DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
845 # Contents between <script> tags are now completely removed if <script>

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

939 1.5.0, released 2007-03-23
940 ! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
941 doesn't actually do anything yet, but keep your eyes peeled.
942 ! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
943 ! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
