1.204_05 Tue 21 Jul 2009
	Summary:
	- Bug fixes in preparation for production release

	Details:
	- There is no longer any real reason to bundle the testing modules
	  except as a potential source of more bugs.
	- Removed quantifier ? on zero-length ^ in /^?for(?:each)?\z/
	- Run-time load PPI::Document instal of compile-time loading it
	- Tweak a few load orders to get PPI::Util loaded earlier.
	- Fixed location access methods on PPI::Element
	- New PPI::Statement::Include::version_literal() method.

1.204_04 Thu 16 Jul 2009
	Summary:
	- Dependency tweaks

	Details:
	- Because we bundle Test::ClassAPI, we need to explicitly match its
	  dependencies. Bumped Params::Util to 1.00.
	- Bumped a couple of deps a couple of revisions to get better XS.

1.204_03 Tue 14 Jul 2009
	Summary:
	- More bug fixing, clean up, and optimisation
	- Cleaning up contributed APIs
	- Adding some demonstration classes

	Details:
	- Implemented PPI::Transform::UpdateCopyright
	- Removed the use of 'use base'
	- Various minor simplifications
	- Renamed PPI::Statement::Switch to ::Given
	- Renamed PPI::Structure::WhenMatch to ::When
	- Converted the Lexer internals to use exception-based error
	  handling.
	- Take advantage of the removal of all those "or return undef"
	  to simplify the Lexer code, remove variable declarations, and
	  inline calls to several hot-code-path functions. The Lexer
	  should be significantly faster (FSDO "significant").
	- The v6 key on Tokenizer broke support for Perl 5.6
	  (perl thought it was a numeric v-string)

1.204_02 Sun 10 May 2009
	Summary:
	- Various bug fixing and stabilisation work
	- It's a perl 5.10 extravaganza!

	Details:
	- Updated Module::Install to 0.87
	- Added Test::NoWarnings to the test suite
	- Added support for qw{foo} in addition to for ('foo')
	- Added support for vstrings again
	- Now supports the 5.10 "state" keyword.
	  (As far as PPI is concerned it's a synonym for "my")
	- Now supports switch statements.
	- Now supports the smart match operator (~~).
	- Now supports keeping track of line numbers and file names as
	  affected by the #line directive.
	- Now supports UNITCHECK blocks.

	  logical_line_number(), and logical_filename() implemented.
	- Support for Unicode byte order marks (PPI::Token::BOM) added.
	- Token::Word::method_call() implemented.
	- Element::descendant_of() and Element::ancestor_of() implemented.
	- Statement::specialized() implemented.
	- Now can handle files named "0".

1.204_01 Sun 18 May 2008
        Summary:
        - Unicode cleanup and bug fixing
	- Taking the opportunity to do some house cleaning while the
	  code base is relatively stable, before things get crazy again.

        - Moved capability detection into PPI::Util
