	- Bug fixes in preparation for production release

	- There is no longer any real reason to bundle the testing modules
	  except as a potential source of more bugs.

	  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_01 Sun 18 May 2008
        - 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.

	  which triggered a bug in the tokenizer during
	  CPAN::Metrics tinderboxing.
	- All open() calls now use three-argument form
	- Upgrading explicit Perl dependency to 5.006,
	  because of the previous item.
	- Better support for labels, including tricky ones like "BEGIN : { ... }"

	  (Did not apply the patch, but fixed a bug noted as an aside in the report)
	- PPI::Document::File was returning a plain PPI::Document object, fixed.

	- PPI is now Editor-compatible.
	- You can create a PPI::Document from random ASCII line noise!

	  detectably-failing 3-or-less character long Perl programs
	  (not inclusive of latin-1 or Unicode). (Audrey Tang)
	- Fixed bug for incomplete <READLINE> quotes at EOF
	  (there may be a few more similar cases)

1.103    Thu Oct  6 2005
	- Small bug fix that shouldn't have escaped
