- + Sub-comment
- . Internal change
-==========================
-
-4.12.0, released 2019-10-27
-! PHP 7.4 is supported, thank you Witold Wasiczko, Mateuz Turcza and
- Edi Modrić
-- PHPDocs for HTMLModule::addElement() and Bool attr are fixed (thanks
- Mateusz)
-
-4.11.0, released 2019-07-14
-# SafeScripting now matches case-sensitively against its whitelist (previously it was
- case-insensitive.) Thanks Dimitri Gritsajuk <gritsajuk.dimitri@gmail.com>
- for reporting.
-! New directive %Core.AllowParseManyTags which allows parsing of many nested tags.
- Thanks M. Suzuki <msuzuki1986@gmail.com> for contributing the patch.
-! purifyArray now supports multidimensional arrays. Thanks
- Sandro Miguel Marques <sandromiguel@sandromiguel.com> for contributing this patch.
-! initial and inherit settings available for width, height, and the min-/max-
- versions thereof. Thanks Michael Kliewe <info@phpgansta.de> for contributing
- this patch.
-! More color names are supported. Thanks Daijobou for contributing.
-- Compatibility fixes for PHP 7.3, including new CI for PHP 7.3
- (thank you Lukas Neumann <lksnmnn@gmail.com>) and removal of
- reserved words in our constants (thanks Darko Hrgovic <darko@darkodev.com>
-- Compatibility fixes for HHVM. Thanks Mateusz Turcza for contributing
- this fix.
-- HTML Purifier now never defines __autoload, fixing #196. Thanks
- Michael Kliewe for reporting.
-- In some situations, Config.php would report an undefined index: class
- error; this has been fixed. Thanks DiLong Fa for contributing
- this fix.
-- We no longer produce <script /> tags; we always explicitly write
- out the open and close tag. Thanks Dimitri Gritsajuk
- <gritsajuk.dimitri@gmail.com> for contributing this fix.
-- Better compatibility when IDNA constants are not present. Thanks
- Mateusz Turcza <xemlock@gmail.com> for contributing this fix.
-
-4.10.0, released 2018-02-22
-# PHP 5.3 is no longer officially supported by HTML Purifier
- (we did not specifically break support, but we are no longer
- testing on PHP 5.3)
-! Relative CSS length units are now supported
-- A few PHP 7.2 compatibility fixes, thanks John Flatness
- <john@zerocrates.org>
-- Improve portability with old versions of libxml which don't
- support accessing the data of a node
-- IDNA2008 is now used for converting domains to ASCII, fixing
- some rather strange bugs with international domains
-- Fix race condition resulting in E_WARNING when creating
- directories with Serializer
-
-4.9.3, released 2017-06-02
-- Workaround PHP 7.1 infinite loop when opcode cache is enabled.
- Thanks @Xiphin (#134, #135)
-- Don't use autoloader when testing for DOMDocument. Hypothetically,
- this could cause your install to start using DirectLex if you had
- previously been monkeypatching in a custom, autoloaded implementation
- of DOMDocument. Don't do that. Thanks @Izumi-kun (#130)
-
-4.9.2, released 2017-03-12
-- Fixes PHP 5.3 compatibility
-- Fix breakage when decoding decimal entities. Thanks @rybakit (#129)
-
-4.9.1, released 2017-03-08
-! %URI.DefaultScheme can now be set to null, in which case
- all relative paths are removed.
-! New CSS properties: min-width, max-width, min-height, max-height (#94)
-! Transparency (rgba) and hsl/hsla supported where color CSS is present.
- Thanks @fxbt for contributing the patch. (#118)
-- When idn_to_ascii is defined, we might accept malformed
- hostnames. Apply validation to the result in such cases.
-- Close directory when done in Serializer DefinitionCache (#100)
-- Deleted some asserts to avoid linters from choking (#97)
-- Rework Serializer cache behavior to avoid chmod'ing if possible (#32)
-- Embedded semicolons in strings in CSS are now handled correctly!
-- We accidentally dropped certain Unicode characters if there was
- one or more invalid characters. This has been fixed, thanks
- to mpyw <ryosuke_i_628@yahoo.co.jp>
-- Fix for "Don't truncate upon encountering </div> when using DOMLex"
- caused a regression with HTML 4.01 Strict parsing with libxml 2.9.1
- (and maybe later versions, but known OK with libxml 2.9.4). The
- fix is to go about handling truncation a bit more cleverly so that
- we can wrap with divs (sidestepping the bug) but slurping out the
- rest of the text in case it ran off the end. (#78)
-- Fix PREG_BACKTRACK_LIMIT_ERROR in HTMLPurifier_Filter_ExtractStyle.
- Thanks @breathbath for contributing the report and fix (#120)
-- Fix entity decoding algorithm to be more conservative about
- decoding entities that are missing trailing semicolon.
- To get old behavior, set %Core.LegacyEntityDecoder to true.
- (#119)
-- Workaround libxml bug when HTML tags are embedded inside
- script tags. To disable workaround set %Core.AggressivelyRemoveScript
- to false. (#83)
-# By default, when a link has a target attribute associated
- with it, we now also add rel="noopener" in order to
- prevent the new window from being able to overwrite
- the original frame. To disable this protection,
- set %HTML.TargetNoopener to FALSE.
-
-4.9.0 was cut on Git but never properly released; when we did the
-real release we decided to skip this version number.
-
-4.8.0, released 2016-07-16
-# By default, when a link has a target attribute associated
- with it, we now also add rel="noreferrer" in order to
- prevent the new window from being able to overwrite
- the original frame. To disable this protection,
- set %HTML.TargetNoreferrer to FALSE.
-! Full PHP 7 compatibility, the test suite is ALL GO.
-! %CSS.AllowDuplicates permits duplicate CSS properties.
-! Support for 'tel' URIs.
-! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
- The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
- yet supported.
-! %Attr.ID.HTML5 turns on HTML5-style ID handling.
-- alt truncation could result in malformed UTF-8 sequence. Don't
- truncate. Thanks Brandon Farber for reporting.
-- Linkify regex is smarter, based off of Gruber's regex.
-- IDNA supported natively on PHP 5.3 and later.
-- Non all-numeric top-level names (e.g., foo.1f, 1f) are now
- allowed.
-- Minor bounds error fix to squash a PHP 7 notice.
-- Support non-/tmp temporary directories for data:// validation
-- Give a better error message when a user attempts to allow
- ul/ol without allowing li.
-- On some versions of PHP, the Serializer DefinitionCache could
- infinite loop when the directory exists but is not listable. (#49)
-- Don't match for <body> inside comments with
- %Core.ConvertDocumentToFragment. (#67)
-- SafeObject is now less case sensitive. (#57)
-- AutoFormat.RemoveEmpty.Predicate now correctly renders in
- web form. (#85)
-
-4.7.0, released 2015-08-04
-# opacity is now considered a "tricky" CSS property rather than a
- proprietary one.
-! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
- an element should be considered "empty" (maybe preserve if it
- has attributes), and modify iframe support so that the iframe
- is removed if it is missing a src attribute. Thanks meeva for
- reporting.
-- Don't truncate upon encountering </div> when using DOMLex. Thanks
- Myrto Christina for finally convincing me to fix this.
-- Update YouTube filter for new code.
-- Fix parsing of rgb() values with spaces in them for 'border'
- attribute.
-- Don't remove foo="" attributes if foo is a boolean attribute. Thanks
- valME for reporting.
-
-4.6.0, released 2013-11-30
-# Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
- Please update any verification scripts you may have.
-# URI parsing algorithm was made more strict, so only prefixes which
- looks like schemes will actually be schemes. Thanks
- Michael Gusev <mgusev@sugarcrm.com> for fixing.
-# %Core.EscapeInvalidChildren is no longer supported, and no longer does
- anything.
-! New directive %Core.AllowHostnameUnderscore which allows underscores
- in hostnames.
-- Eliminate quadratic behavior in DOMLex by using a proper queue.
- Thanks Ole Laursen for noticing this.
-- Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
- behavior in the rest of the purificaiton pipeline. Thanks Chedburn
- Networks for sponsoring this work.
-- Made Linkify URL parser a bit less permissive, so that non-breaking
- spaces and commas are not included as part of URL. Thanks nAS for fixing.
-- Fix some bad interactions with %HTML.Allowed and injectors. Thanks
- David Hirtz for reporting.
-- Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
- for reporting.
-
-4.5.0, released 2013-02-17
-# Fix bug where stacked attribute transforms clobber each other;
- this also means it's no longer possible to override attribute
- transforms in later modules. No internal code was using this
- but this may break some clients.
-# We now use SHA-1 to identify cached definitions, instead of MD5.
-! Support display:inline-block
-! Support for more white-space CSS values.
-! Permit underscores in font families
-! Support for page-break-* CSS3 properties when proprietary properties
- are enabled.
-! New directive %Core.DisableExcludes; can be set to 'true' to turn off
- SGML excludes checking. If HTML Purifier is removing too much text
- and you don't care about full standards compliance, try setting this to
- 'true'.
-- Use prepend for SPL autoloading on PHP 5.3 and later.
-- Fix bug with nofollow transform when pre-existing rel exists.
-- Fix bug where background:url() always gets lower-cased
- (but not background-image:url())
-- Fix bug with non lower-case color names in HTML
-- Fix bug where data URI validation doesn't remove temporary files.

-- Don't remove certain empty tags on RemoveEmpty.
-
-4.4.0, released 2012-01-18
-# Removed PEARSax3 handler.
-# URI.Munge now munges URIs inside the same host that go from https
- to http. Reported by Neike Taika-Tessaro.
-# Core.EscapeNonASCIICharacters now always transforms entities to
- entities, even if target encoding is UTF-8.
-# Tighten up selector validation in ExtractStyleBlocks.
- Non-syntactically valid selectors are now rejected, along with
- some of the more obscure ones such as attribute selectors, the
- :lang pseudoselector, and anything not in CSS2.1. Furthermore,
- ID and class selectors now work properly with the relevant
- configuration attributes. Also, mute errors when parsing CSS
- with CSS Tidy. Reported by Mario Heiderich and Norman Hippert.
-! Added support for 'scope' attribute on tables.
-! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links.
-! Properly handle sub-lists directly nested inside of lists in
- a standards compliant way, by moving them into the preceding <li>
-! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for
- limited allowed comments in untrusted situations.
-! Implement iframes, and allow them to be used in untrusted mode with
- %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle
- <brad.froehle@gmail.com> for submitting an initial version of the patch.
-! The Forms module now works properly for transitional doctypes.
-! Added support for internationalized domain names. You need the PEAR
- Net_IDNA2 module to be in your path; if it is installed, ensure the
- class can be loaded and then set %Core.EnableIDNA to true.
-- Color keywords are now case insensitive. Thanks Yzmir Ramirez
- <yramirez-htmlpurifier@adicio.com> for reporting.
-- Explicitly initialize anonModule variable to null.
-- Do not duplicate nofollow if already present. Thanks 178
- for reporting.
-- Do not add nofollow if hostname matches our current host. Thanks 178
- for reporting, and Neike Taika-Tessaro for helping diagnose.
-- Do not unset parser variable; this fixes intermittent serialization
- problems. Thanks Neike Taika-Tessaro for reporting, bill
- <10010tiger@gmail.com> for diagnosing.
-- Fix iconv truncation bug, where non-UTF-8 target encodings see
- output truncated after around 8000 characters. Thanks Jörg Ludwig
- <joerg.ludwig@iserv.eu> for reporting.
-- Fix broken table content model for XHTML1.1 (and also earlier
- versions, although the W3C validator doesn't catch those violations).
- Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
-
-4.3.0, released 2011-03-27
-# Fixed broken caching of customized raw definitions, but requires an
- API change. The old API still works but will emit a warning,
- see http://htmlpurifier.org/docs/enduser-customize.html#optimized
- for how to upgrade your code.
-# Protect against Internet Explorer innerHTML behavior by specially
- treating attributes with backticks but no angled brackets, quotes or
- spaces. This constitutes a slight semantic change, which can be
- reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro
- and Mario Heiderich.
-# Protect against cssText/innerHTML by restricting allowed characters
- used in fonts further than mandated by the specification and encoding
- some extra special characters in URLs. Reported by Neike
- Taika-Tessaro and Mario Heiderich.
-! Added %HTML.Nofollow to add rel="nofollow" to external links.

- from running out of stack space for deeply nested documents.
- Thanks Maxim Krizhanovsky for contributing a patch.
-- Make removal of conditional IE comments ungreedy; thanks Bernd
- for reporting.
-- Escape CDATA before removing Internet Explorer comments.
-- Fix removal of id attributes under certain conditions by ensuring
- armor attributes are preserved when recreating tags.
-- Check if schema.ser was corrupted.
-- Check if zend.ze1_compatibility_mode is on, and error out if it is.
- This safety check is only done for HTMLPurifier.auto.php; if you
- are using standalone or the specialized includes files, you're
- expected to know what you're doing.
-- Stop repeatedly writing the cache file after I'm done customizing a
- raw definition. Reported by ajh.
-- Switch to using require_once in the Bootstrap to work around bad
- interaction with Zend Debugger and APC. Reported by Antonio Parraga.
-- Fix URI handling when hostname is missing but scheme is present.
- Reported by Neike Taika-Tessaro.
-- Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro
- for reporting.
-- Fix harmless notice from indexing into empty string. Thanks Matthijs
- Kooijman <matthijs@stdin.nl> for reporting.
-- Don't autoclose no parent elements are able to support the element
- that triggered the autoclose. In particular fixes strange behavior
- of stray <li> tags. Thanks pkuliga@gmail.com for reporting and
- Neike Taika-Tessaro <pinkgothic@gmail.com> for debugging assistance.
-
-4.2.0, released 2010-09-15
-! Added %Core.RemoveProcessingInstructions, which lets you remove
- <? ... ?> statements.
-! Added %URI.DisableResources functionality; the directive originally
- did nothing. Thanks David Rothstein for reporting.
-! Add documentation about configuration directive types.
-! Add %CSS.ForbiddenProperties configuration directive.
-! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
- to utilize full-screen mode.
-! Add optional support for the <code>file</code> URI scheme, enable
- by explicitly setting %URI.AllowedSchemes.
-! Add %Core.NormalizeNewlines options to allow turning off newline
- normalization.
-- Fix improper handling of Internet Explorer conditional comments
- by parser. Thanks zmonteca for reporting.
-- Fix missing attributes bug when running on Mac Snow Leopard and APC.
- Thanks sidepodcast for the fix.
-- Warn if an element is allowed, but an attribute it requires is
- not allowed.
-
-4.1.1, released 2010-05-31
-- Fix undefined index warnings in maintenance scripts.
-- Fix bug in DirectLex for parsing elements with a single attribute
- with entities.
-- Rewrite CSS output logic for font-family and url(). Thanks Mario
- Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
- Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
-- Emit an error for CollectErrors if a body is extracted
-- Fix bug where in background-position for center keyword handling.
-- Fix infinite loop when a wrapper element is inserted in a context
- where it's not allowed. Thanks Lars <lars@renoz.dk> for reporting.

-
-4.1.0, released 2010-04-26
-! Support proprietary height attribute on table element

- %URI.AllowedSchemes
-! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
-! Support for Internet Explorer compatibility with %HTML.SafeObject

-! Handle <ol><ol> properly, by inserting the necessary <li> tag.
-- Always quote the insides of url(...) in CSS.
-
-4.0.0, released 2009-07-07
-# APIs for ConfigSchema subsystem have substantially changed. See
- docs/dev-config-bcbreaks.txt for details; in essence, anything that
- had both namespace and directive now have a single unified key.
-# Some configuration directives were renamed, specifically:
- %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
- %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
- %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
- %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
- As usual, the old directive names will still work, but will throw E_NOTICE
- errors.
-# The allowed values for class have been relaxed to allow all of CDATA for
- doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set
- %Attr.ClassUseCDATA to false.
-# Instead of appending the content model to an old content model, a blank
- element will replace the old content model. You can use #SUPER to get
- the old content model.
-! More robust support for name="" and id=""
-! HTMLPurifier_Config::inherit($config) allows you to inherit one
- configuration, and have changes to that configuration be propagated
- to all of its children.
-! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
- the name attribute when set. Use with care. Thanks Ian Cook for
- sponsoring.
-! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
- tags that contain non-breaking spaces as well other whitespace. You
- can also modify which tags should have &nbsp; maintained with
- %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
-! Implement %Attr.AllowedClasses, which allows administrators to restrict
- classes users can use to a specified finite set of classes, and
- %Attr.ForbiddenClasses, which is the logical inverse.
-! You can now maintain your own configuration schema directories by
- creating a config-schema.php file or passing an extra argument. Check
- docs/dev-config-schema.html for more details.
-! Added HTMLPurifier_Config->serialize() method, which lets you save away
- your configuration in a compact serial file, which you can unserialize
- and use directly without having to go through the overhead of setup.
-- Fix bug where URIDefinition would not get cleared if it's directives got
- changed.
-- Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
-- Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
-- Make %URI.Munge not apply to links that have the same host as your host.
-- Prevent stray </body> tag from truncating output, if a second </body>
- is present.
-. Created script maintenance/rename-config.php for renaming a configuration
- directive while maintaining its alias. This script does not change source code.
-. Implement namespace locking for definition construction, to prevent
- bugs where a directive is used for definition construction but is not
- used to construct the cache hash.
-
-3.3.0, released 2009-02-16
-! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
-! Implement generic property list classess
-- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
- does not do the "right thing" with characters not supported in the output
- set.
-- Spellcheck UTF-8: The Secret To Character Encoding
-- Fix improper removal of the contents of elements with only whitespace. Thanks
- Eric Wald for reporting.
-- Fix broken test suite in versions of PHP without spl_autoload_register()
-- Fix degenerate case with YouTube filter involving double hyphens.
- Thanks Pierre Attar for reporting.
-- Fix YouTube rendering problem on certain versions of Firefox.
-- Fix CSSDefinition Printer problems with decorators
-- Add text parameter to unit tests, forces text output
-. Add verbose mode to command line test runner, use (--verbose)
-. Turn on unit tests for UnitConverter
-. Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
-. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
- tested on Linux.
-. Removed trailing whitespace from all text files, see
- remote-trailing-whitespace.php maintenance script.
-. Convert configuration to use property list backend.
-
-3.2.0, released 2008-10-31
-# Using %Core.CollectErrors forces line number/column tracking on, whereas
- previously you could theoretically turn it off.
-# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
- use handleEnd() instead.
-! %Output.AttrSort for when you need your attributes in alphabetical order to
- deal with a bug in FCKEditor. Requested by frank farmer.
-! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
-! Proper support for name attribute. It is now allowed and equivalent to the id
- attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
- is heavy (for all doctypes).
-! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
- use on hand-written HTML.
-! Add error-cases for unsupported elements in MakeWellFormed. This enables
- the strategy to be used, standalone, on untrusted input.
-! %Core.AggressivelyFixLt is on by default. This causes more sensible
- processing of left angled brackets in smileys and other whatnot.
-! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
- 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
- the --only-phpt parameter, although for backwards-compatibility the flag
- will still work.
-! AutoParagraph auto-formatter will now preserve double-newlines upon output.
- Users who are not performing inbound filtering, this may seem a little
- useless, but as a bonus, the test suite and handling of edge cases is also
- improved.
-! Experimental implementation of forms for %HTML.Trusted
-! Track column numbers when maintain line numbers is on
-! Proprietary 'background' attribute on table-related elements converted into
- corresponding CSS. Thanks Fusemail for sponsoring this feature!
-! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
- supertype.
-! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
- time of operation varies slightly from notifyEnd() as *all* end tokens are
- processed by the injector before they are subject to the well-formedness rules.
-! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
- basename of image when not present.
-! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
-- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
- the other involving an undefined $is_folder error.
-- Throw error when %Core.Encoding is set to a spurious value. Previously,
- this errored silently and returned false.
-- Redirected stderr to stdout for flush error output.
-- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
- available.
-- Do not re-munge URL if the output URL has the same host as the input URL.
- Requested by Chris.
-- Fix error in documentation regarding %Filter.ExtractStyleBlocks
-- Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
-- Fix bug with inline elements in blockquotes conflicting with strict doctype
-- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
-- Fix bug where dots and double-dots in absolute URLs without hostname were
- not collapsed by URIFilter_MakeAbsolute.
-- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
- by reordering their addition.
-- Will now throw exception on many error conditions during lexer creation; also
- throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
- is being used.
-- Detect if domxml extension is loaded, and use DirectLEx accordingly.
-- Improve handling of big numbers with floating point arithmetic in UnitConverter.
- Reported by David Morton.
-. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
- for more interesting filter-backtracking
-. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
- index to reprocess tokens.
-. StringHashParser now allows for multiline sections with "empty" content;
- previously the section would remain undefined.
-. Added --quick option to multitest.php, which tests only the most recent
- release for each series.
-. Added --distro option to multitest.php, which accepts either 'normal' or
- 'standalone'. This supercedes --exclude-normal and --exclude-standalone
-
-3.1.1, released 2008-06-19
-# %URI.Munge now, by default, does not munge resources (for example, <img src="">)
- In order to enable this again, please set %URI.MungeResources to true.
-! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
- and height/width HTML with %HTML.MaxImgLength.
-! %URI.MungeSecretKey for secure URI munging. Thanks Chris
- for sponsoring this feature. Check out the corresponding documentation
- for details. (Att Nightly testers: The API for this feature changed before
- the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
- %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
-! Implemented post URI filtering. Set member variable $post to true to set
- a URIFilter as such.
-! Allow modules to define injectors via $info_injector. Injectors are
- automatically disabled if injector's needed elements are not found.
-! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
- Thanks Chris for sponsoring. If you've been using ad hoc code from the
- forums, PLEASE use this instead.
-! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
- embedded, tag name, attribute name, CSS property name). See %URI.Munge
- for more details. Requested by Jochem Blok.
-- Disable percent height/width attributes for img.
-- AttrValidator operations are now atomic; updates to attributes are not
- manifest in token until end of operations. This prevents naughty internal
- code from directly modifying CurrentToken when they're not supposed to.
- This semantics change was requested by frank farmer.
-- Percent encoding checks enabled for URI query and fragment
-- Fix stray backslashes in font-family; CSS Unicode character escapes are
- now properly resolved (although *only* in font-family). Thanks Takeshi Terada
- for reporting.
-- Improve parseCDATA algorithm to take into account newline normalization
-- Account for browser confusion between Yen character and backslash in
- Shift_JIS encoding. This fix generalizes to any other encoding which is not
- a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
-- Fix missing configuration parameter in Generator calls. Thanks vs for the
- partial patch.
-- Improved adherence to Unicode by checking for non-character codepoints.
- Thanks Geoffrey Sneddon for reporting. This may result in degraded
- performance for extremely large inputs.
-- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
- for reporting.
-. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
- handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
- this class.
-. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
- to __construct($min, $max). __construct(true) is equivalent to
- __construct('0').
-. Added HTMLPurifier_AttrDef_Switch class
-. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
- up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
- get this called with the configuration object. All modules now
- use this rather than __construct(), although legacy code using constructors
- will still work--the new format, however, lets modules access the
- configuration object for HTML namespace dependant tweaks.
-. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
-. ConfigSchema data-structure heavily optimized; on average it uses a third
- the memory it did previously. The interface has changed accordingly,
- consult changes to HTMLPurifier_Config for details.
-. Variable parsing types now are magic integers instead of strings
-. Added benchmark for ConfigSchema
-. HTMLPurifier_Generator requires $config and $context parameters. If you
- don't know what they should be, use HTMLPurifier_Config::createDefault()
- and new HTMLPurifier_Context().
-. Printers now properly distinguish between output configuration, and
- target configuration. This is not applicable to scripts using
- the Printers for HTML Purifier related tasks.
-. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
- fatal errors will ensue.
-. URIFilter->prepare can return false in order to abort loading of the filter
-. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
- an external resource.
-. %URI.Munge functionality factored out into a post-filter class.
-. Added CurrentCSSProperty context variable during CSS validation
-
-3.1.0, released 2008-05-18
-# Unnecessary references to objects (vestiges of PHP4) removed from method
- signatures. The following methods do not need references when assigning from
- them and will result in E_STRICT errors if you try:
- + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
- + HTMLPurifier_ConfigSchema::instance()
- + HTMLPurifier_DefinitionCacheFactory::instance()
- + HTMLPurifier_DefinitionCacheFactory->create()
- + HTMLPurifier_DoctypeRegistry->register()
- + HTMLPurifier_DoctypeRegistry->get()
- + HTMLPurifier_HTMLModule->addElement()
- + HTMLPurifier_HTMLModule->addBlankElement()
- + HTMLPurifier_LanguageFactory::instance()
-# Printer_ConfigForm's get*() functions were static-ified
-# %HTML.ForbiddenAttributes requires attribute declarations to be in the
- form of tag@attr, NOT tag.attr (which will throw an error and won't do
- anything). This is for forwards compatibility with XML; you'd do best
- to migrate an %HTML.AllowedAttributes directives to this syntax too.
-! Allow index to be false for config from form creation
-! Added HTMLPurifier::VERSION constant
-! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
- and allows for version numbers like "3.1.0-dev".
-! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
-! HTML Purifier's URI handling is a lot more robust, with much stricter
- validation checks and better percent encoding handling. Thanks Gareth Heyes
- for indicating security vulnerabilities from lax percent encoding.
-! Bootstrap autoloader deals more robustly with classes that don't exist,
- preventing class_exists($class, true) from barfing.
-- InterchangeBuilder now alphabetizes its lists
-- Validation error in configdoc output fixed
-- Iconv and other encoding errors muted even with custom error handlers that
- do not honor error_reporting

-- Fixed and revamped broken ConfigForm smoketest
-- Bug with bool/null fields in Printer_ConfigForm fixed
-- Bug with global forbidden attributes fixed
-- Improved error messages for allowed and forbidden HTML elements and attributes
-- Missing (or null) in configdoc documentation restored
-- If DOM throws and exception during parsing with PH5P (occurs in newer versions
- of DOM), HTML Purifier punts to DirectLex
-- Fatal error with unserialization of ScriptRequired
-- Created directories are now chmod'ed properly
-- Fixed bug with fallback languages in LanguageFactory
-- Standalone testing setup properly with autoload
-. Out-of-date documentation revised
-. UTF-8 encoding check optimization as suggested by Diego
-. HTMLPurifier_Error removed in favor of exceptions
-. More copy() function removed; should use clone instead
-. More extensive unit tests for HTMLDefinition
-. assertPurification moved to central harness
-. HTMLPurifier_Generator accepts $config and $context parameters during
- instantiation, not runtime
-. Double-quotes outside of attribute values are now unescaped
-
-3.1.0rc1, released 2008-04-22
-# Autoload support added. Internal require_once's removed in favor of an
- explicit require list or autoloading. To use HTML Purifier,
- you must now either use HTMLPurifier.auto.php
- or HTMLPurifier.includes.php; setting the include path and including
- HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
- as well to register our autoload handler (or modify your autoload function
- to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
- HTMLPurifier.safe-includes.php for a less performance friendly but more
- user-friendly library load.
-# HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
- information is stored in the ConfigSchema directory, and the
- maintenance/generate-schema-cache.php generates the schema.ser file, which
- is now instantiated. Support for userland schema changes coming soon!
-# HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
- alias; to get rid of these errors just modify your configuration to use
- the new directive name.
-# HTMLPurifier->addFilter is deprecated; built-in filters can now be
- enabled using %Filter.$filter_name or by setting your own filters using
- %Filter.Custom
-# Directive-level safety properties superceded in favor of module-level
- safety. Internal method HTMLModule->addElement() has changed, although
- the externally visible HTMLDefinition->addElement has *not* changed.
-! Extra utility classes for testing and non-library operations can
- be found in extras/. Specifically, these are FSTools and ConfigDoc.
- You may find a use for these in your own project, but right now they
- are highly experimental and volatile.
-! Integration with PHPT allows for automated smoketests
-! Limited support for proprietary HTML elements, namely <marquee>, sponsored
- by Chris. You can enable them with %HTML.Proprietary if your client
- demands them.
-! Support for !important CSS cascade modifier. By default, this will be stripped
- from CSS, but you can enable it using %CSS.AllowImportant
-! Support for display and visibility CSS properties added, set %CSS.AllowTricky
- to true to use them.
-! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
- Developer error (not enduser error) can cause these to be triggered.
-! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
-! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
- mucking around with HTMLPurifier_CSSDefinition
-! ConfigDoc output has been enhanced with version and deprecation info.
-! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
-- Autoclose now operates iteratively, i.e. <span><span><div> now has
- both span tags closed.
-- Various HTMLPurifier_Config convenience functions now accept another parameter
- $schema which defines what HTMLPurifier_ConfigSchema to use besides the
- global default.
-- Fix bug with trusted script handling in libxml versions later than 2.6.28.
-- Fix bug in ExtractStyleBlocks with comments in style tags
-- Fix bug in comment parsing for DirectLex
-- Flush output now displayed when in command line mode for unit tester

- on the same element without emitting errors.
-- Fixed fatal error in PH5P lexer with invalid tag names
-. Plugins now get their own changelogs according to project conventions.
-. Convert tokens to use instanceof, reducing memory footprint and
- improving comparison speed.
-. Dry runs now supported in SimpleTest; testing facilities improved
-. Bootstrap class added for handling autoloading functionality
-. Implemented recursive glob at FSTools->globr
-. ConfigSchema now has instance methods for all corresponding define*
- static methods.
-. A couple of new historical maintenance scripts were added.
-. HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
-. tests/index.php can now be run from any directory.
-. HTMLPurifier_Token subclasses split into seperate files
-. HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
-. HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
-. New --php=php flag added, allows PHP executable to be specified (command
- line only!)
-. htmlpurifier_add_test() preferred method to translate test files in to
- classes, because it handles PHPT files too.
-. Debugger class is deprecated and will be removed soon.
-. Command line argument parsing for testing scripts revamped, now --opt value
- format is supported.
-. Smoketests now cleanup after magic quotes
-. Generator now can output comments (however, comments are still stripped
- from HTML Purifier output)
-. HTMLPurifier_ConfigSchema->validate() deprecated in favor of
- HTMLPurifier_VarParser->parse()

-. copy() methods removed in favor of clone keyword
-
-3.0.0, released 2008-01-06

- <http://csstidy.sourceforge.net/>. You can access the blocks with the
- 'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
- The output CSS can also be "scoped" for a specific element, use:
- %Filter.ExtractStyleBlocksScope

- fixed (does not manifest on default tag-set)
-- Spurious internal content reorganization error suppressed
-- HTMLDefinition->addElement now returns a reference to the created
- element object, as implied by the documentation

-
-2.1.2, released 2007-09-03
-! Implemented Object module for trusted users
-! Implemented experimental HTML5 parsing mode using PH5P. To use, add
- this to your code:
- require_once 'HTMLPurifier/Lexer/PH5P.php';
- $config->set('Core', 'LexerImpl', 'PH5P');
- Note that this Lexer introduces some classes not in the HTMLPurifier
- namespace. Also, this is PHP5 only.
-! CSS property border-spacing implemented
-- Fix non-visible parsing error in DirectLex with empty tags that have
- slashes inside attribute values.
-- Fix typo in CSS definition: border-collapse:seperate; was incorrectly
- accepted as valid CSS. Usually non-visible, because this styling is the
- default for tables in most browsers. Thanks Brett Zamir for pointing
- this out.
-- Fix validation errors in configuration form

-
-2.1.0, released 2007-08-02
-# flush-htmldefinition-cache.php superseded in favor of a generic
- flush-definition-cache.php script, you can clear a specific cache
- by passing its name as a parameter to the script
-! Phorum mod implemented for HTML Purifier
-! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
- trigger HTML removal in PHP5 (DOMLex). This directive is not necessary

- %HTML.Allowed
-. ConfigForm generates textareas instead of text inputs for lists, hashes,
- lookups, text and itext fields
-. Hidden element content removal genericized: %Core.HiddenElements can
- be used to customize this behavior, by default <script> and <style> are
- hidden
-. Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
-. Custom ChildDef added to default include list
-. URIScheme reflection improved: will not attempt to include file if class
- already exists. May clobber autoload, so I need to keep an eye on it
-. ConfigSchema heavily optimized, will only collect information and validate
- definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
-. AttrDef_URI unit tests and implementation refactored
-. benchmarks/ directory now protected from public view with .htaccess file;

-! Experimental AutoFormat functionality added: auto-paragraph and
- linkify your HTML input by setting %AutoFormat.AutoParagraph and
- %AutoFormat.Linkify to true
-! Newlines normalized internally, and then converted back to the
- value of PHP_EOL. If this is not desired, set your newline format
- using %Output.Newline.

- cases involving Lexing or Strategies
-- Clean up special case code for <script> tags

- others when revision numbers are unequal
-- Improve Serializer DefinitionCache directory permissions checks
-- DefinitionCache no longer throws errors when it encounters old
- serial files that do not conform to the current style

-. %HTML.Doctype is now constrained by specific values, to specify a custom
- doctype use new %HTML.CustomDoctype
-. ConfigForm truncates long directives to keep the form small, and does
- not re-output namespaces
-

-# Completely refactored HTMLModuleManager, decentralizing safety
- information
-# Transform modules changed to Tidy modules, which offer more flexibility
- and better modularization

- off, but it's not recommended.
-# New compact syntax for AttrDef objects that can be used to instantiate
- new objects via make()
-# Definitions (esp. HTMLDefinition) are now cached for a significant
- performance boost. You can disable caching by setting %Core.DefinitionCache
