= KEY ====================
    # Breaks back-compat
    ! Feature
    - Bugfix
      + Sub-comment
    . Internal change
==========================

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.EnableExcludes; can be set to 'false' 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
  'false'.
- 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.
  Thanks Javier Marín Ros <javiermarinros@gmail.com> for reporting.
- 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.
! 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 <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.
- 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 <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 injector
