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

1.4.0, unknown release date (around Christmas, hopefully)
(major feature release)

1.3.2, unknown release date, may be dropped
(security/bugfix/minor feature release)
! HTMLPurifier object now accepts configuration arrays, no need to manually
  instantiate a configuration object
! Context object now accessible to outside
! Added enduser-youtube.html, explains how to embed YouTube videos. See
  also corresponding smoketest preserveYouTube.php.
! Added purifyArray(), which takes a list of HTML and purifies it all
- printDefinition.php: added labels, added better clarification
. HTMLPurifier_Config::create() added, takes mixed variable and converts into
  a HTMLPurifier_Config object.

1.3.1, released 2006-12-06
! Added HTMLPurifier.func.php stub for a convenient function to call the library
- Fixed bug in RemoveInvalidImg code that caused all images to be dropped
  (thanks to .mario for reporting this)
. Standardized all attribute handling variables to attr, made it plural

1.3.0, released 2006-11-26
# Invalid images are now removed, rather than replaced with a dud
  <img src="" alt="Invalid image" />. Previous behavior can be restored
  with new directive %Core.RemoveInvalidImg set to false.
! (X)HTML Strict now supported
  + Transparently handles inline elements in block context (blockquote)
! Added GET method to demo for easier validation, added 50kb max input size
! New directive %HTML.BlockWrapper, for block-ifying inline elements
! New directive %HTML.Parent, allows you to only allow inline content
! New directives %HTML.AllowedElements and %HTML.AllowedAttributes to let
  users narrow the set of allowed tags
! <li value="4"> and <ul start="2"> now allowed in loose mode
! New directives %URI.DisableExternalResources and %URI.DisableResources
! New directive %Attr.DisableURI, which eliminates all hyperlinking
! New directive %URI.Munge, munges URI so you can use some sort of redirector
  service to avoid PageRank leaks or warn users that they are exiting your site.
! Added spiffy new smoketest printDefinition.php, which lets you twiddle with
  the configuration settings and see how the internal rules are affected.
! New directive %URI.HostBlacklist for blocking links to bad hosts.
  xssAttacks.php smoketest updated accordingly.
- Added missing type to ChildDef_Chameleon
- Remove Tidy option from demo if there is not Tidy available
. ChildDef_Required guards against empty tags
. Lookup table HTMLDefinition->info_flow_elements added
. Added peace-of-mind variable initialization to Strategy_FixNesting
. Added HTMLPurifier->info_parent_def, parent child processing made special
. Added internal documents briefly summarizing future progression of HTML
. HTMLPurifier_Config->getBatch($namespace) added
. More lenient casting to bool from string in HTMLPurifier_ConfigSchema
. Refactored ChildDef classes into their own files

1.2.0, released 2006-11-19
# ID attributes now disabled by default. New directives:
  + %HTML.EnableAttrID - restores old behavior by allowing IDs
  + %Attr.IDPrefix - %Attr.IDBlacklist alternative that munges all user IDs
    so that they don't collide with your IDs
  + %Attr.IDPrefixLocal - Same as above, but for when there are multiple
    instances of user content on the page
  + Profuse documentation on how to use these available in docs/enduser-id.txt
! Added MODx plugin <http://modxcms.com/forums/index.php/topic,6604.0.html>
! Added percent encoding normalization
! XSS attacks smoketest given facelift
! Configuration documentation now has table of contents
! Added %URI.DisableExternal, which prevents links to external websites.  You
  can also use %URI.Host to permit absolute linking to subdomains
! Non-accessible resources (ex. mailto) blocked from embedded URIs (img src)
