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

3.1.0, unknown release date
# 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)).
# 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!
! Extra utility classes for testing and non-library operations can
  be found in extras/. Specifically, these are FSTools and ConfigSchema.
  You may find a use for these in your own project, but right now they
  are highly experimental and volatile.
- Autoclose now operates iteratively, i.e. <span><span><div> now has
  both span tags closed.
. 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

3.0.0, released 2008-01-06
# HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained
  until PHP 4 is completely deprecated, but no new features will be added
  to it.
  + Visibility declarations added
  + Constructor methods renamed to __construct()
  + PHP4 reference cruft removed (in progress)
! CSS properties are now case-insensitive
! DefinitionCacheFactory now can register new implementations
! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting <style> from
  documents and cleaning their contents up. Requires the CSSTidy library
  <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
! Experimental support for some proprietary CSS attributes allowed:
  opacity (and all of the browser-specific equivalents) and scrollbar colors.
  Enable by setting %CSS.Proprietary to true.
- Colors missing # but in hex form will be corrected
- CSS Number algorithm improved
- Unit testing and multi-testing now on steroids: command lines,
  XML output, and other goodies now added.
. Unit tests for Injector improved
. New classes:
  + HTMLPurifier_AttrDef_CSS_AlphaValue
  + HTMLPurifier_AttrDef_CSS_Filter
. Multitest now has a file docblock

2.1.3, released 2007-11-05
! tests/multitest.php allows you to test multiple versions by running
  tests/index.php through multiple interpreters using `phpv` shell
  script (you must provide this script!)
- Fixed poor include ordering for Email URI AttrDefs, causes fatal errors
  on some systems.
- Injector algorithm further refined: off-by-one error regarding skip 
  counts for dormant injectors fixed
- Corrective blockquote definition now enabled for HTML 4.01 Strict
- Fatal error when <img> tag (or any other element with required attributes)
  has 'id' attribute fixed, thanks NykO18 for reporting
- Fix warning emitted when a non-supported URI scheme is passed to the
  MakeAbsolute URIFilter, thanks NykO18 (again)
- Further refine AutoParagraph injector. Behavior inside of elements
  allowing paragraph tags clarified: only inline content delimeted by
  double newlines (not block elements) are paragraphed.
- Buggy treatment of end tags of elements that have required attributes
  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
- Phorum mod's HTML Purifier help message expanded (unreleased elsewhere)
- Fix a theoretical class of infinite loops from DirectLex reported
  by Nate Abele
- Work around unnecessary DOMElement type-cast in PH5P that caused errors
  in PHP 5.1
- Work around PHP 4 SimpleTest lack-of-error complaining for one-time-only
  HTMLDefinition errors, this may indicate problems with error-collecting
  facilities in PHP 5
- Make ErrorCollectorEMock work in both PHP 4 and PHP 5
- Make PH5P work with PHP 5.0 by removing unnecessary array parameter typedef
. %Core.AcceptFullDocuments renamed to %Core.ConvertDocumentToFragment 
  to better communicate its purpose
. Error unit tests can now specify the expectation of no errors. Future
  iterations of the harness will be extremely strict about what errors
  are allowed
. Extend Injector hooks to allow for more powerful injector routines
. HTMLDefinition->addBlankElement created, as according to the HTMLModule
  method
. Doxygen configuration file updated, with minor improvements
. Test runner now checks for similarly named files in conf/ directory too.
. Minor cosmetic change to flush-definition-cache.php: trailing newline is
  outputted
. Maintenance script for generating PH5P patch added, original PH5P source
  file also added under version control
. Full unit test runner script title made more descriptive with PHP version
. Updated INSTALL file to state that 4.3.7 is the earliest version we
  are actively testing

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
- Hammer out a bunch of edge-case bugs in the standalone distribution
- Inclusion reflection removed from URISchemeRegistry; you must manually
  include any new schema files you wish to use
- Numerous typo fixes in documentation thanks to Brett Zamir
. Unit test refactoring for one logical test per test function
. Config and context parameters in ComplexHarness deprecated: instead, edit
  the $config and $context member variables
. HTML wrapper in DOMLex now takes DTD identifiers into account; doesn't
  really make a difference, but is good for completeness sake
. merge-library.php script refactored for greater code reusability and
  PHP4 compatibility

2.1.1, released 2007-08-04
- Fix show-stopper bug in %URI.MakeAbsolute functionality
- Fix PHP4 syntax error in standalone version
. Add prefix directory to include path for standalone, this prevents
  other installations from clobbering the standalone's URI schemes
. Single test methods can be invoked by prefixing with __only

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
  for PHP4 (DirectLex).
! Standalone file now available, which greatly reduces the amount of
  includes (although there are still a few files that reside in the
  standalone folder)
! Relative URIs can now be transformed into their absolute equivalents
  using %URI.Base and %URI.MakeAbsolute
! Ruby implemented for XHTML 1.1
! You can now define custom URI filtering behavior, see enduser-uri-filter.html
  for more details
! UTF-8 font names now supported in CSS
- AutoFormatters emit friendly error messages if tags or attributes they
  need are not allowed
- ConfigForm's compactification of directive names is now configurable
- AutoParagraph autoformatter algorithm refined after field-testing
- XHTML 1.1 now applies XHTML 1.0 Strict cleanup routines, namely
  blockquote wrapping
- Contents of <style> tags removed by default when tags are removed
. HTMLPurifier_Config->getSerial() implemented, this is extremely useful
  for output cache invalidation
. ConfigForm printer now can retrieve CSS and JS files as strings, in
  case HTML Purifier's directory is not publically accessible
. Introduce new text/itext configuration directive values: these represent
  longer strings that would be more appropriately edited with a textarea
. Allow newlines to act as separators for lists, hashes, lookups and
  %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;
  run the tests via command line
. URI scheme is munged off if there is no authority and the scheme is the
  default one
. All unit tests inherit from HTMLPurifier_Harness, not UnitTestCase
. Interface for URIScheme changed
. Generic URI object to hold components of URI added, most systems involved
  in URI validation have been migrated to use it
. Custom filtering for URIs factored out to URIDefinition interface for
  maximum extensibility

2.0.1, released 2007-06-27
! Tag auto-closing now based on a ChildDef heuristic rather than a
  manually set auto_close array; some behavior may change
! 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.
! Beta error collection, messages are implemented for the most generic
  cases involving Lexing or Strategies
- Clean up special case code for <script> tags
- Reorder includes for DefinitionCache decorators, fixes a possible
  missing class error
- Fixed bug where manually modified definitions were not saved via cache
  (mostly harmless, except for the fact that it would be a little slower)
- Configuration objects with different serials do not clobber each
  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
- Stray xmlns attributes removed from configuration documentation
- configForm.php smoketest no longer has XSS vulnerability due to
  unescaped print_r output
- Printer adheres to configuration's directives on output format
- Fix improperly named form field in ConfigForm printer
. Rewire some test-cases to swallow errors rather than expect them
. HTMLDefinition printer updated with some of the new attributes
. DefinitionCache keys reordered to reflect precedence: version number,
  hash, then revision number
. %Core.DefinitionCache renamed to %Cache.DefinitionImpl
. Interlinking in configuration documentation added using
  Injector_PurifierLinkify
. Directives now keep track of aliases to themselves
. Error collector now requires a severity to be passed, use PHP's internal
  error constants for this
. HTMLPurifier_Config::getAllowedDirectivesForForm implemented, allows
  much easier selective embedding of configuration values
. Doctype objects now accept public and system DTD identifiers
. %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

2.0.0, released 2007-06-20
# Completely refactored HTMLModuleManager, decentralizing safety
  information
# Transform modules changed to Tidy modules, which offer more flexibility
  and better modularization
# Configuration object now finalizes itself when a read operation is
  performed on it, ensuring that its internal state stays consistent.
  To revert this behavior, you can set the $autoFinalize member variable 
  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
  to null. You CANNOT edit raw definitions without setting the corresponding
  DefinitionID directive (%HTML.DefinitionID for HTMLDefinition).
# Contents between <script> tags are now completely removed if <script>
  is not allowed
# Prototype-declarations for Lexer removed in favor of configuration
  determination of Lexer implementations.

  honor error_reporting is used
- StrictBlockquote child definition refrains from wrapping whitespace
  in tags now.

  false positives
. Unit test for ElementDef created, ElementDef behavior modified to
  be more flexible

. AttrTypes now has accessor functions that should be used instead
  of directly manipulating info
. TagTransform_Center deprecated in favor of generic TagTransform_Simple

  + hspace and vspace in img
  + size and noshade in hr
  + nowrap in td
  + clear in br
  + align in caption, table, img and hr
  + type in ul, ol and li
! DirectLex now preserves text in which a < bracket is followed by
  a non-alphanumeric character. This means that certain emoticons
  are now preserved.
! %Core.RemoveInvalidImg is now operational, when set to false invalid
  images will hang around with an empty src
! target attribute in a tag supported, use %Attr.AllowedFrameTargets
  to enable
! CSS property white-space now allows nowrap (supported in all modern
  browsers) but not others (which have spotty browser implementations)
! XHTML 1.1 mode now sort-of works without any fatal errors, and
  lang is now moved over to xml:lang.
! Attribute transformation smoketest available at smoketests/attrTransform.php
! Transformation of font's size attribute now handles super-large numbers
- Possibly fatal bug with __autoload() fixed in module manager
- Invert HTMLModuleManager->addModule() processing order to check
  prefixes first and then the literal module

  an empty string in them.
- Merging in attribute lists now works.
. Demo script removed: it has been added to the website's repository
. Basic.php script modified to work out of the box
. Refactor AttrTransform classes to reduce duplication
. AttrTransform_TextAlign axed in favor of a more general
  AttrTransform_EnumToCSS, refer to HTMLModule/TransformToStrict.php to
  see how the new equivalent is implemented

  %Attr.IDBlacklistRegexp
- Error messages are emitted when you attempt to "allow" elements or
  attributes that HTML Purifier does not support
- Fix segfault in unit test. The problem is not very reproduceable and
  I don't know what causes it, but a six line patch fixed it.

1.5.0, released 2007-03-23
! Added a rudimentary I18N and L10N system modeled off MediaWiki. It
  doesn't actually do anything yet, but keep your eyes peeled.
! docs/enduser-utf8.html explains how to use UTF-8 and HTML Purifier
! Newly structured HTMLDefinition modeled off of XHTML 1.1 modules.
  I am loathe to release beta quality APIs, but this is exactly that;
  don't use the internal interfaces if you're not willing to do migration
  later on.

. Added support for IDREF attributes (i.e. for)
. Renamed HTMLPurifier_AttrDef_Class to HTMLPurifier_AttrDef_Nmtokens

  is false when you're not inline and an integer of the parent that
  caused you to become inline when you are (so possibly zero)
. Removed ElementDef->type in favor of ElementDef->descendants_are_inline
  and HTMLDefinition->content_sets
. StrictBlockquote now reports what elements its supposed to allow,
  rather than what it does allow
. Removed HTMLDefinition->info_flow_elements in favor of
  HTMLDefinition->content_sets['Flow']
. Removed redundant "exclusionary" definitions from DTD roster
. StrictBlockquote now requires a construction parameter as if it
  were an Required ChildDef, this is the "real" set of allowed elements
. AttrDef partitioned into HTML, CSS and URI segments
