  1. NEWS ( CHANGELOG and HISTORY ) HTMLPurifier
  2. |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
  3. = KEY ====================
  4. # Breaks back-compat
  5. ! Feature
  6. - Bugfix
  7. + Sub-comment
  8. . Internal change
  9. ==========================
  10. 4.6.0, released 2013-11-30
  11. # Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
  12. Please update any verification scripts you may have.
  13. # URI parsing algorithm was made more strict, so only prefixes which
  14. looks like schemes will actually be schemes. Thanks
  15. Michael Gusev <mgusev@sugarcrm.com> for fixing.
  16. # %Core.EscapeInvalidChildren is no longer supported, and no longer does
  17. anything.
  18. ! New directive %Core.AllowHostnameUnderscore which allows underscores
  19. in hostnames.
  20. - Eliminate quadratic behavior in DOMLex by using a proper queue.
  21. Thanks Ole Laursen for noticing this.
  22. - Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
  23. behavior in the rest of the purificaiton pipeline. Thanks Chedburn
  24. Networks for sponsoring this work.
  25. - Made Linkify URL parser a bit less permissive, so that non-breaking
  26. spaces and commas are not included as part of URL. Thanks nAS for fixing.
  27. - Fix some bad interactions with %HTML.Allowed and injectors. Thanks
  28. David Hirtz for reporting.
  29. - Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
  30. for reporting.
  31. 4.5.0, released 2013-02-17
  32. # Fix bug where stacked attribute transforms clobber each other;
  33. this also means it's no longer possible to override attribute
  34. transforms in later modules. No internal code was using this
  35. but this may break some clients.
  36. # We now use SHA-1 to identify cached definitions, instead of MD5.
  37. ! Support display:inline-block
  38. ! Support for more white-space CSS values.
  39. ! Permit underscores in font families
  40. ! Support for page-break-* CSS3 properties when proprietary properties
  41. are enabled.
  42. ! New directive %Core.DisableExcludes; can be set to 'true' to turn off
  43. SGML excludes checking. If HTML Purifier is removing too much text
  44. and you don't care about full standards compliance, try setting this to
  45. 'true'.
  46. - Use prepend for SPL autoloading on PHP 5.3 and later.
  47. - Fix bug with nofollow transform when pre-existing rel exists.
  48. - Fix bug where background:url() always gets lower-cased
  49. (but not background-image:url())
  50. - Fix bug with non lower-case color names in HTML
  51. - Fix bug where data URI validation doesn't remove temporary files.
  52. Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
  53. - Don't remove certain empty tags on RemoveEmpty.
  54. 4.4.0, released 2012-01-18
  55. # Removed PEARSax3 handler.
  56. # URI.Munge now munges URIs inside the same host that go from https
  57. to http. Reported by Neike Taika-Tessaro.
  58. # Core.EscapeNonASCIICharacters now always transforms entities to
  59. entities, even if target encoding is UTF-8.
  60. # Tighten up selector validation in ExtractStyleBlocks.
  61. Non-syntactically valid selectors are now rejected, along with
  62. some of the more obscure ones such as attribute selectors, the
  63. :lang pseudoselector, and anything not in CSS2.1. Furthermore,
  64. ID and class selectors now work properly with the relevant
  65. configuration attributes. Also, mute errors when parsing CSS
  66. with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
  67. ! Added support for 'scope' attribute on tables.
  68. ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
  69. ! Properly handle sub-lists directly nested inside of lists in
  70. a standards compliant way, by moving them into the preceding <li>
  71. ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
  72. limited allowed comments in untrusted situations.
  73. ! Implement iframes, and allow them to be used in untrusted mode with
  74. %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
  75. <brad.froehle@gmail.com> for submitting an initial version of the patch.
  76. ! The Forms module now works properly for transitional doctypes.
  77. ! Added support for internationalized domain names. You need the PEAR
  78. Net_IDNA2 module to be in your path; if it is installed, ensure the
  79. class can be loaded and then set %Core.EnableIDNA to true.
  80. - Color keywords are now case insensitive. Thanks Yzmir Ramirez
  81. <yramirez-htmlpurifier@adicio.com> for reporting.
  82. - Explicitly initialize anonModule variable to null.
  83. - Do not duplicate nofollow if already present. Thanks 178
  84. for reporting.
  85. - Do not add nofollow if hostname matches our current host. Thanks 178
  86. for reporting, and Neike Taika-Tessaro for helping diagnose.
  87. - Do not unset parser variable; this fixes intermittent serialization
  88. problems. Thanks Neike Taika-Tessaro for reporting, bill
  89. <10010tiger@gmail.com> for diagnosing.
  90. - Fix iconv truncation bug, where non-UTF-8 target encodings see
  91. output truncated after around 8000 characters. Thanks Jörg Ludwig
  92. <joerg.ludwig@iserv.eu> for reporting.
  93. - Fix broken table content model for XHTML1.1 (and also earlier
  94. versions, although the W3C validator doesn't catch those violations).
  95. Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
  96. 4.3.0, released 2011-03-27
  97. # Fixed broken caching of customized raw definitions, but requires an
  98. API change. The old API still works but will emit a warning,
  99. see http://htmlpurifier.org/docs/enduser-customize.html#optimized
  100. for how to upgrade your code.
  101. # Protect against Internet Explorer innerHTML behavior by specially
  102. treating attributes with backticks but no angled brackets, quotes or
  103. spaces. This constitutes a slight semantic change, which can be
  104. reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
  105. and Mario Heiderich.
  106. # Protect against cssText/innerHTML by restricting allowed characters
  107. used in fonts further than mandated by the specification and encoding
  108. some extra special characters in URLs. Reported by Neike
  109. Taika-Tessaro and Mario Heiderich.
  110. ! Added %HTML.Nofollow to add rel="nofollow" to external links.
  111. ! More types of SPL autoloaders allowed on later versions of PHP.
  112. ! Implementations for position, top, left, right, bottom, z-index
  113. when %CSS.Trusted is on.
  114. ! Add %Cache.SerializerPermissions option for custom serializer
  115. directory/file permissions
  116. ! Fix longstanding bug in Flash support for non-IE browsers, and
  117. allow more wmode attributes.
  118. ! Add %CSS.AllowedFonts to restrict permissible font names.
  119. - Switch to an iterative traversal of the DOM, which prevents us
  120. from running out of stack space for deeply nested documents.
  121. Thanks Maxim Krizhanovsky for contributing a patch.
  122. - Make removal of conditional IE comments ungreedy; thanks Bernd
  123. for reporting.
  124. - Escape CDATA before removing Internet Explorer comments.
  125. - Fix removal of id attributes under certain conditions by ensuring
  126. armor attributes are preserved when recreating tags.
  127. - Check if schema.ser was corrupted.
  128. - Check if zend.ze1_compatibility_mode is on, and error out if it is.
  129. This safety check is only done for HTMLPurifier.auto.php; if you
  130. are using standalone or the specialized includes files, you're
  131. expected to know what you're doing.
  132. - Stop repeatedly writing the cache file after I'm done customizing a
  133. raw definition. Reported by ajh.
  134. - Switch to using require_once in the Bootstrap to work around bad
  135. interaction with Zend Debugger and APC. Reported by Antonio Parraga.
  136. - Fix URI handling when hostname is missing but scheme is present.
  137. Reported by Neike Taika-Tessaro.
  138. - Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
  139. for reporting.
  140. - Fix harmless notice from indexing into empty string. Thanks Matthijs
  141. Kooijman <matthijs@stdin.nl> for reporting.
  142. - Don't autoclose no parent elements are able to support the element
  143. that triggered the autoclose. In particular fixes strange behavior
  144. of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
  145. Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
  146. 4.2.0, released 2010-09-15
  147. ! Added %Core.RemoveProcessingInstructions, which lets you remove
  148. <? ... ?> statements.
  149. ! Added %URI.DisableResources functionality; the directive originally
  150. did nothing. Thanks David Rothstein for reporting.
  151. ! Add documentation about configuration directive types.
  152. ! Add %CSS.ForbiddenProperties configuration directive.
  153. ! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
  154. to utilize full-screen mode.
  155. ! Add optional support for the <code>file</code> URI scheme, enable
  156. by explicitly setting %URI.AllowedSchemes.
  157. ! Add %Core.NormalizeNewlines options to allow turning off newline
  158. normalization.
  159. - Fix improper handling of Internet Explorer conditional comments
  160. by parser. Thanks zmonteca for reporting.
  161. - Fix missing attributes bug when running on Mac Snow Leopard and APC.
  162. Thanks sidepodcast for the fix.
  163. - Warn if an element is allowed, but an attribute it requires is
  164. not allowed.
  165. 4.1.1, released 2010-05-31
  166. - Fix undefined index warnings in maintenance scripts.
  167. - Fix bug in DirectLex for parsing elements with a single attribute
  168. with entities.
  169. - Rewrite CSS output logic for font-family and url(). Thanks Mario
  170. Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
  171. Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
  172. - Emit an error for CollectErrors if a body is extracted
  173. - Fix bug where in background-position for center keyword handling.
  174. - Fix infinite loop when a wrapper element is inserted in a context
  175. where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.
  176. - Remove +x bit and shebang from index.php; only supported mode is to
  177. explicitly call it with php.
  178. - Make test script less chatty when log_errors is on.
  179. 4.1.0, released 2010-04-26
  180. ! Support proprietary height attribute on table element
  181. ! Support YouTube slideshows that contain /cp/ in their URL.
  182. ! Support for data: URI scheme; not enabled by default, add it using
  183. %URI.AllowedSchemes
  184. ! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
  185. ! Support for Internet Explorer compatibility with %HTML.SafeObject
  186. using %Output.FlashCompat.
  187. ! Handle <ol><ol> properly, by inserting the necessary <li> tag.
  188. - Always quote the insides of url(...) in CSS.
  189. 4.0.0, released 2009-07-07
  190. # APIs for ConfigSchema subsystem have substantially changed. See
  191. docs/dev-config-bcbreaks.txt for details; in essence, anything that
  192. had both namespace and directive now have a single unified key.
  193. # Some configuration directives were renamed, specifically:
  194. %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
  195. %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
  196. %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
  197. %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
  198. As usual, the old directive names will still work, but will throw E_NOTICE
  199. errors.
  200. # The allowed values for class have been relaxed to allow all of CDATA for
  201. doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
  202. %Attr.ClassUseCDATA to false.
  203. # Instead of appending the content model to an old content model, a blank
  204. element will replace the old content model. You can use #SUPER to get
  205. the old content model.
  206. ! More robust support for name="" and id=""
  207. ! HTMLPurifier_Config::inherit($config) allows you to inherit one
  208. configuration, and have changes to that configuration be propagated
  209. to all of its children.
  210. ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
  211. the name attribute when set. Use with care. Thanks Ian Cook for
  212. sponsoring.
  213. ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
  214. tags that contain non-breaking spaces as well other whitespace. You
  215. can also modify which tags should have &nbsp; maintained with
  216. %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
  217. ! Implement %Attr.AllowedClasses, which allows administrators to restrict
  218. classes users can use to a specified finite set of classes, and
  219. %Attr.ForbiddenClasses, which is the logical inverse.
  220. ! You can now maintain your own configuration schema directories by
  221. creating a config-schema.php file or passing an extra argument. Check
  222. docs/dev-config-schema.html for more details.
  223. ! Added HTMLPurifier_Config->serialize() method, which lets you save away
  224. your configuration in a compact serial file, which you can unserialize
  225. and use directly without having to go through the overhead of setup.
  226. - Fix bug where URIDefinition would not get cleared if it's directives got
  227. changed.
  228. - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
  229. - Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
  230. - Make %URI.Munge not apply to links that have the same host as your host.
  231. - Prevent stray </body> tag from truncating output, if a second </body>
  232. is present.
  233. . Created script maintenance/rename-config.php for renaming a configuration
  234. directive while maintaining its alias. This script does not change source code.
  235. . Implement namespace locking for definition construction, to prevent
  236. bugs where a directive is used for definition construction but is not
  237. used to construct the cache hash.
  238. 3.3.0, released 2009-02-16
  239. ! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
  240. ! Implement generic property list classess
  241. - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
  242. does not do the "right thing" with characters not supported in the output
  243. set.
  244. - Spellcheck UTF-8: The Secret To Character Encoding
  245. - Fix improper removal of the contents of elements with only whitespace. Thanks
  246. Eric Wald for reporting.
  247. - Fix broken test suite in versions of PHP without spl_autoload_register()
  248. - Fix degenerate case with YouTube filter involving double hyphens.
  249. Thanks Pierre Attar for reporting.
  250. - Fix YouTube rendering problem on certain versions of Firefox.
  251. - Fix CSSDefinition Printer problems with decorators
  252. - Add text parameter to unit tests, forces text output
  253. . Add verbose mode to command line test runner, use (--verbose)
  254. . Turn on unit tests for UnitConverter
  255. . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
  256. . Fix newline errors that caused spurious failures when CRLF HTML Purifier was
  257. tested on Linux.
  258. . Removed trailing whitespace from all text files, see
  259. remote-trailing-whitespace.php maintenance script.
  260. . Convert configuration to use property list backend.
  261. 3.2.0, released 2008-10-31
  262. # Using %Core.CollectErrors forces line number/column tracking on, whereas
  263. previously you could theoretically turn it off.
  264. # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
  265. use handleEnd() instead.
  266. ! %Output.AttrSort for when you need your attributes in alphabetical order to
  267. deal with a bug in FCKEditor. Requested by frank farmer.
  268. ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
  269. ! Proper support for name attribute. It is now allowed and equivalent to the id
  270. attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
  271. is heavy (for all doctypes).
  272. ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
  273. use on hand-written HTML.
  274. ! Add error-cases for unsupported elements in MakeWellFormed. This enables
  275. the strategy to be used, standalone, on untrusted input.
  276. ! %Core.AggressivelyFixLt is on by default. This causes more sensible
  277. processing of left angled brackets in smileys and other whatnot.
  278. ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
  279. 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
  280. the --only-phpt parameter, although for backwards-compatibility the flag
  281. will still work.
  282. ! AutoParagraph auto-formatter will now preserve double-newlines upon output.
  283. Users who are not performing inbound filtering, this may seem a little
  284. useless, but as a bonus, the test suite and handling of edge cases is also
  285. improved.
  286. ! Experimental implementation of forms for %HTML.Trusted
  287. ! Track column numbers when maintain line numbers is on
  288. ! Proprietary 'background' attribute on table-related elements converted into
  289. corresponding CSS. Thanks Fusemail for sponsoring this feature!
  290. ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
  291. supertype.
  292. ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
  293. time of operation varies slightly from notifyEnd() as *all* end tokens are
  294. processed by the injector before they are subject to the well-formedness rules.
  295. ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
  296. basename of image when not present.
  297. ! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
  298. - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
  299. the other involving an undefined $is_folder error.
  300. - Throw error when %Core.Encoding is set to a spurious value. Previously,
  301. this errored silently and returned false.
  302. - Redirected stderr to stdout for flush error output.
  303. - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
  304. available.
  305. - Do not re-munge URL if the output URL has the same host as the input URL.
  306. Requested by Chris.
  307. - Fix error in documentation regarding %Filter.ExtractStyleBlocks
  308. - Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
  309. - Fix bug with inline elements in blockquotes conflicting with strict doctype
  310. - Detect if HTML support is disabled for DOM by checking for loadHTML() method.
  311. - Fix bug where dots and double-dots in absolute URLs without hostname were
  312. not collapsed by URIFilter_MakeAbsolute.
  313. - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
  314. by reordering their addition.
  315. - Will now throw exception on many error conditions during lexer creation; also
  316. throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
  317. is being used.
  318. - Detect if domxml extension is loaded, and use DirectLEx accordingly.
  319. - Improve handling of big numbers with floating point arithmetic in UnitConverter.
  320. Reported by David Morton.
  321. . Strategy_MakeWellFormed now operates in-place, saving memory and allowing
  322. for more interesting filter-backtracking
  323. . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
  324. index to reprocess tokens.
  325. . StringHashParser now allows for multiline sections with "empty" content;
  326. previously the section would remain undefined.
  327. . Added --quick option to multitest.php, which tests only the most recent
  328. release for each series.
  329. . Added --distro option to multitest.php, which accepts either 'normal' or
  330. 'standalone'. This supercedes --exclude-normal and --exclude-standalone
  331. 3.1.1, released 2008-06-19
  332. # %URI.Munge now, by default, does not munge resources (for example, <img src="">)
  333. In order to enable this again, please set %URI.MungeResources to true.
  334. ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
  335. and height/width HTML with %HTML.MaxImgLength.
  336. ! %URI.MungeSecretKey for secure URI munging. Thanks Chris
  337. for sponsoring this feature. Check out the corresponding documentation
  338. for details. (Att Nightly testers: The API for this feature changed before
  339. the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
  340. %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
  341. ! Implemented post URI filtering. Set member variable $post to true to set
  342. a URIFilter as such.
  343. ! Allow modules to define injectors via $info_injector. Injectors are
  344. automatically disabled if injector's needed elements are not found.
  345. ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
  346. Thanks Chris for sponsoring. If you've been using ad hoc code from the
  347. forums, PLEASE use this instead.
  348. ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
  349. embedded, tag name, attribute name, CSS property name). See %URI.Munge
  350. for more details. Requested by Jochem Blok.
  351. - Disable percent height/width attributes for img.
  352. - AttrValidator operations are now atomic; updates to attributes are not
  353. manifest in token until end of operations. This prevents naughty internal
  354. code from directly modifying CurrentToken when they're not supposed to.
  355. This semantics change was requested by frank farmer.
  356. - Percent encoding checks enabled for URI query and fragment
  357. - Fix stray backslashes in font-family; CSS Unicode character escapes are
  358. now properly resolved (although *only* in font-family). Thanks Takeshi Terada
  359. for reporting.
  360. - Improve parseCDATA algorithm to take into account newline normalization
  361. - Account for browser confusion between Yen character and backslash in
  362. Shift_JIS encoding. This fix generalizes to any other encoding which is not
  363. a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
  364. - Fix missing configuration parameter in Generator calls. Thanks vs for the
  365. partial patch.
  366. - Improved adherence to Unicode by checking for non-character codepoints.
  367. Thanks Geoffrey Sneddon for reporting. This may result in degraded
  368. performance for extremely large inputs.
  369. - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
  370. for reporting.
  371. . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
  372. handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
  373. this class.
  374. . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
  375. to __construct($min, $max). __construct(true) is equivalent to
  376. __construct('0').
  377. . Added HTMLPurifier_AttrDef_Switch class
  378. . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
  379. up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
  380. get this called with the configuration object. All modules now
  381. use this rather than __construct(), although legacy code using constructors
  382. will still work--the new format, however, lets modules access the
  383. configuration object for HTML namespace dependant tweaks.
  384. . AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
  385. . ConfigSchema data-structure heavily optimized; on average it uses a third
  386. the memory it did previously. The interface has changed accordingly,
  387. consult changes to HTMLPurifier_Config for details.
  388. . Variable parsing types now are magic integers instead of strings
  389. . Added benchmark for ConfigSchema
  390. . HTMLPurifier_Generator requires $config and $context parameters. If you
  391. don't know what they should be, use HTMLPurifier_Config::createDefault()
  392. and new HTMLPurifier_Context().
  393. . Printers now properly distinguish between output configuration, and
  394. target configuration. This is not applicable to scripts using
  395. the Printers for HTML Purifier related tasks.
  396. . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
  397. fatal errors will ensue.
  398. . URIFilter->prepare can return false in order to abort loading of the filter
  399. . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
  400. an external resource.
  401. . %URI.Munge functionality factored out into a post-filter class.
  402. . Added CurrentCSSProperty context variable during CSS validation
  403. 3.1.0, released 2008-05-18
  404. # Unnecessary references to objects (vestiges of PHP4) removed from method
  405. signatures. The following methods do not need references when assigning from
  406. them and will result in E_STRICT errors if you try:
  407. + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
  408. + HTMLPurifier_ConfigSchema::instance()
  409. + HTMLPurifier_DefinitionCacheFactory::instance()
  410. + HTMLPurifier_DefinitionCacheFactory->create()
  411. + HTMLPurifier_DoctypeRegistry->register()
  412. + HTMLPurifier_DoctypeRegistry->get()
  413. + HTMLPurifier_HTMLModule->addElement()
  414. + HTMLPurifier_HTMLModule->addBlankElement()
  415. + HTMLPurifier_LanguageFactory::instance()
  416. # Printer_ConfigForm's get*() functions were static-ified
  417. # %HTML.ForbiddenAttributes requires attribute declarations to be in the
  418. form of tag@attr, NOT tag.attr (which will throw an error and won't do
  419. anything). This is for forwards compatibility with XML; you'd do best
  420. to migrate an %HTML.AllowedAttributes directives to this syntax too.
  421. ! Allow index to be false for config from form creation
  422. ! Added HTMLPurifier::VERSION constant
  423. ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
  424. and allows for version numbers like "3.1.0-dev".
  425. ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
  426. ! HTML Purifier's URI handling is a lot more robust, with much stricter
  427. validation checks and better percent encoding handling. Thanks Gareth Heyes
  428. for indicating security vulnerabilities from lax percent encoding.
  429. ! Bootstrap autoloader deals more robustly with classes that don't exist,
  430. preventing class_exists($class, true) from barfing.
  431. - InterchangeBuilder now alphabetizes its lists
  432. - Validation error in configdoc output fixed
  433. - Iconv and other encoding errors muted even with custom error handlers that
  434. do not honor error_reporting
  435. - Add protection against imagecrash attack with CSS height/width
  436. - HTMLPurifier::instance() created for consistency, is equivalent to getInstance()
  437. - Fixed and revamped broken ConfigForm smoketest
  438. - Bug with bool/null fields in Printer_ConfigForm fixed
  439. - Bug with global forbidden attributes fixed
  440. - Improved error messages for allowed and forbidden HTML elements and attributes
  441. - Missing (or null) in configdoc documentation restored
  442. - If DOM throws and exception during parsing with PH5P (occurs in newer versions
  443. of DOM), HTML Purifier punts to DirectLex
  444. - Fatal error with unserialization of ScriptRequired
  445. - Created directories are now chmod'ed properly
  446. - Fixed bug with fallback languages in LanguageFactory
  447. - Standalone testing setup properly with autoload
  448. . Out-of-date documentation revised
  449. . UTF-8 encoding check optimization as suggested by Diego
  450. . HTMLPurifier_Error removed in favor of exceptions
  451. . More copy() function removed; should use clone instead
  452. . More extensive unit tests for HTMLDefinition
  453. . assertPurification moved to central harness
  454. . HTMLPurifier_Generator accepts $config and $context parameters during
  455. instantiation, not runtime
  456. . Double-quotes outside of attribute values are now unescaped
  457. 3.1.0rc1, released 2008-04-22
  458. # Autoload support added. Internal require_once's removed in favor of an
  459. explicit require list or autoloading. To use HTML Purifier,
  460. you must now either use HTMLPurifier.auto.php
  461. or HTMLPurifier.includes.php; setting the include path and including
  462. HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
  463. as well to register our autoload handler (or modify your autoload function
  464. to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
  465. HTMLPurifier.safe-includes.php for a less performance friendly but more
  466. user-friendly library load.
  467. # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
  468. information is stored in the ConfigSchema directory, and the
  469. maintenance/generate-schema-cache.php generates the schema.ser file, which
  470. is now instantiated. Support for userland schema changes coming soon!
  471. # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
  472. alias; to get rid of these errors just modify your configuration to use
  473. the new directive name.
  474. # HTMLPurifier->addFilter is deprecated; built-in filters can now be
  475. enabled using %Filter.$filter_name or by setting your own filters using
  476. %Filter.Custom
  477. # Directive-level safety properties superceded in favor of module-level
  478. safety. Internal method HTMLModule->addElement() has changed, although
  479. the externally visible HTMLDefinition->addElement has *not* changed.
  480. ! Extra utility classes for testing and non-library operations can
  481. be found in extras/. Specifically, these are FSTools and ConfigDoc.
  482. You may find a use for these in your own project, but right now they
  483. are highly experimental and volatile.
  484. ! Integration with PHPT allows for automated smoketests
  485. ! Limited support for proprietary HTML elements, namely <marquee>, sponsored
  486. by Chris. You can enable them with %HTML.Proprietary if your client
  487. demands them.
  488. ! Support for !important CSS cascade modifier. By default, this will be stripped
  489. from CSS, but you can enable it using %CSS.AllowImportant
  490. ! Support for display and visibility CSS properties added, set %CSS.AllowTricky
  491. to true to use them.
  492. ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
  493. Developer error (not enduser error) can cause these to be triggered.
  494. ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
  495. ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
  496. mucking around with HTMLPurifier_CSSDefinition
  497. ! ConfigDoc output has been enhanced with version and deprecation info.
  498. ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
  499. - Autoclose now operates iteratively, i.e. <span><span><div> now has
  500. both span tags closed.
  501. - Various HTMLPurifier_Config convenience functions now accept another parameter
  502. $schema which defines what HTMLPurifier_ConfigSchema to use besides the
  503. global default.
  504. - Fix bug with trusted script handling in libxml versions later than 2.6.28.
  505. - Fix bug in ExtractStyleBlocks with comments in style tags

  527. line only!)
  528. . htmlpurifier_add_test() preferred method to translate test files in to
  529. classes, because it handles PHPT files too.
  530. . Debugger class is deprecated and will be removed soon.
  531. . Command line argument parsing for testing scripts revamped, now --opt value
  532. format is supported.
  533. . Smoketests now cleanup after magic quotes
  534. . Generator now can output comments (however, comments are still stripped
  535. from HTML Purifier output)

  537. HTMLPurifier_VarParser->parse()
  538. . Integers auto-cast into float type by VarParser.

  556. documents and cleaning their contents up. Requires the CSSTidy library
  557. <http://csstidy.sourceforge.net/>. You can access the blocks with the
  558. 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
  559. The output CSS can also be "scoped" for a specific element, use:
  560. %Filter.ExtractStyleBlocksScope
  561. ! Experimental support for some proprietary CSS attributes allowed:
  562. opacity (and all of the browser-specific equivalents) and scrollbar colors.
  563. Enable by setting %CSS.Proprietary to true.
  564. - Colors missing # but in hex form will be corrected
  565. - CSS Number algorithm improved

  585. MakeAbsolute URIFilter, thanks NykO18 (again)
  586. - Further refine AutoParagraph injector. Behavior inside of elements
  587. allowing paragraph tags clarified: only inline content delimeted by

  598. in PHP 5.1
  599. - Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
  600. HTMLDefinition errors, this may indicate problems with error-collecting
  601. facilities in PHP 5
  602. - Make ErrorCollectorEMock work in both PHP 4 and PHP 5
  603. - Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
  604. . %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment
  605. to better communicate its purpose
  606. . Error unit tests can now specify the expectation of no errors. Future
  607. iterations of the harness will be extremely strict about what errors
  608. are allowed
  609. . Extend Injector hooks to allow for more powerful injector routines
  610. . HTMLDefinition->addBlankElement created, as according to the HTMLModule
  611. method

  625. require_once 'HTMLPurifier/Lexer/PH5P.php';
  626. $config->set('Core', 'LexerImpl', 'PH5P');
  627. Note that this Lexer introduces some classes not in the HTMLPurifier
  628. namespace. Also, this is PHP5 only.
  629. ! CSS property border-spacing implemented
  630. - Fix non-visible parsing error in DirectLex with empty tags that have
  631. slashes inside attribute values.
  632. - Fix typo in CSS definition: border-collapse:seperate; was incorrectly
  633. accepted as valid CSS. Usually non-visible, because this styling is the
  634. default for tables in most browsers. Thanks Brett Zamir for pointing
  635. this out.
  636. - Fix validation errors in configuration form
  637. - Hammer out a bunch of edge-case bugs in the standalone distribution

  653. . Single test methods can be invoked by prefixing with __only
  654. 2.1.0, released 2007-08-02
  655. # flush-htmldefinition-cache.php superseded in favor of a generic
  656. flush-definition-cache.php script, you can clear a specific cache
  657. by passing its name as a parameter to the script
  658. ! Phorum mod implemented for HTML Purifier
  659. ! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
  660. trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
  661. for PHP4 (DirectLex).

  678. . HTMLPurifier_Config->getSerial() implemented, this is extremely useful
  679. for output cache invalidation
  680. . ConfigForm printer now can retrieve CSS and JS files as strings, in
  681. case HTML Purifier's directory is not publically accessible
  682. . Introduce new text/itext configuration directive values: these represent
  683. longer strings that would be more appropriately edited with a textarea
  684. . Allow newlines to act as separators for lists, hashes, lookups and
  685. %HTML.Allowed
  686. . ConfigForm generates textareas instead of text inputs for lists, hashes,
  687. lookups, text and itext fields
  688. . Hidden element content removal genericized: %Core.HiddenElements can
  689. be used to customize this behavior, by default <script> and <style> are
  690. hidden
  691. . Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
  692. . Custom ChildDef added to default include list
  693. . URIScheme reflection improved: will not attempt to include file if class
  694. already exists. May clobber autoload, so I need to keep an eye on it
  695. . ConfigSchema heavily optimized, will only collect information and validate
  696. definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
  697. . AttrDef_URI unit tests and implementation refactored
  698. . benchmarks/ directory now protected from public view with .htaccess file;
  699. run the tests via command line

  701. default one
  702. . All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
  703. . Interface for URIScheme changed
  704. . Generic URI object to hold components of URI added, most systems involved
  705. in URI validation have been migrated to use it
  706. . Custom filtering for URIs factored out to URIDefinition interface for
  707. maximum extensibility
  708. 2.0.1, released 2007-06-27
  709. ! Tag auto-closing now based on a ChildDef heuristic rather than a
  710. manually set auto_close array; some behavior may change
  711. ! Experimental AutoFormat functionality added: auto-paragraph and
  712. linkify your HTML input by setting %AutoFormat.AutoParagraph and
  713. %AutoFormat.Linkify to true
  714. ! Newlines normalized internally, and then converted back to the
  715. value of PHP_EOL. If this is not desired, set your newline format

  739. . Interlinking in configuration documentation added using
  740. Injector_PurifierLinkify
  741. . Directives now keep track of aliases to themselves
  742. . Error collector now requires a severity to be passed, use PHP's internal
  743. error constants for this
  744. . HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
  745. much easier selective embedding of configuration values
  746. . Doctype objects now accept public and system DTD identifiers
  747. . %HTML.Doctype is now constrained by specific values, to specify a custom
  748. doctype use new %HTML.CustomDoctype

  753. information
  754. # Transform modules changed to Tidy modules, which offer more flexibility
  755. and better modularization
  756. # Configuration object now finalizes itself when a read operation is
  757. performed on it, ensuring that its internal state stays consistent.
  758. To revert this behavior, you can set the $autoFinalize member variable
  759. off, but it's not recommended.
  760. # New compact syntax for AttrDef objects that can be used to instantiate
  761. new objects via make()
  762. # Definitions (esp. HTMLDefinition) are now cached for a significant
  763. performance boost. You can disable caching by setting %Core.DefinitionCache
  764. to null. You CANNOT edit raw definitions without setting the corresponding
  765. DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
  766. # Contents between <script> tags are now completely removed if <script>
  767. is not allowed
