. Internal change
==========================
4.5.0, unknown release date
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
! 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
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
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
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 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.
! More types of SPL autoloaders allowed on later versions of PHP.
! Implementations for position, top, left, right, bottom, z-index
when %CSS.Trusted is on.
! Add %Cache.SerializerPermissions option for custom serializer
directory/file permissions
! Fix longstanding bug in Flash support for non-IE browsers, and
allow more wmode attributes.
! Add %CSS.AllowedFonts to restrict permissible font names.
- Switch to an iterative traversal of the DOM, which prevents us
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 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 tags. Thanks pkuliga@gmail.com for reporting and
Neike Taika-Tessaro 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 file
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 for reporting and Takeshi
Terada 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 for reporting.
- Remove +x bit and shebang from index.php; only supported mode is to
explicitly call it with php.
- Make test script less chatty when log_errors is on.
4.1.0, released 2010-04-26
! Support proprietary height attribute on table element
! Support YouTube slideshows that contain /cp/ in their URL.
! Support for data: URI scheme; not enabled by default, add it using
%URI.AllowedSchemes
! Support flashvars when using %HTML.SafeObject and %HTML.SafeEmbed.
! Support for Internet Explorer compatibility with %HTML.SafeObject
using %Output.FlashCompat.
! Handle properly, by inserting the necessary - 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 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 http://foo
- Make %URI.Munge not apply to links that have the same host as your host.
- Prevent stray
