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

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.
  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 e
