1.6 Sat Jan 18 15:47:26 GMT 2003
	- moved tests to Test::More

	- removed GraphViz::Remote as it was no longer working
	- new no_overlap graph attribute which tells the graph solver
	  to not overlap the nodes (idea by Chris Ball)
	- added patches by Barrie Slaymaker to make GraphViz
	  work under Win32!
	- this is the Flight 63 edition

1.4 Wed Oct  3 07:57:42 BST 2001
	- added new filehandle, scalar reference, and code reference
	  scheme to as_* to allow streaming of data, rather than
	  accumulating potentially very large output in memory (based
	  on patch by Dave Rolsky)
	- new pagewidth and pageheight graph attributes for creating
	  PostScript mosaics of large graphs (idea by Nelson Loyola)

1.3 Sun Aug 19 15:43:02 BST 2001
	- labels can now contain quotes
	- fixed bug: labels can now start with a number
	- fixed bug in Devel::GraphVizProf so that packages
	  are now grouped seperately (lines with the same text used to
	  be grouped together)
	- fixed undefined warning in GraphViz::Parse::RecDescent
	- increased coverage of tests
	- new 'rank' node attribute allows nodes to be ranked
          at the same level
	- make empty cluster names do nothing (patch by Barrie
	  Slaymaker)

1.2 Fri Aug 10 18:54:21 BST 2001
        - removed the images in the examples directory and added
          a file (make_all.pl) to, errr, make all the images
	- This is the HAL2001 edition

1.1 Tue Jul 24 23:54:42 BST 2001
	- added extra parameter to as_* to allow easy saving of
	  images: $graph->as_png("pretty.png")
	- added new GraphViz::Parse::Yapp module to visualise
	  Parse::Yapp grammars
	- added new GraphViz::Parse::Yacc module to visualise
	  Parse::Yacc grammars

1.00 Thu Jun 14 15:10:28 BST 2001
	- finally released as version 1.00!
	- added a reference to brian d foy's DDJ article on
	  Devel::GraphVizProf
	- put the entire Perl regular expression test suite through
	  GraphViz::Regex and fixed all the bugs
        - no longer sort nodes by default (idea by Stephen Riehm),
          which makes graphs just work better. Not documented, do
          you want it to be?

0.14 Thu May  3 17:57:57 BST 2001
	- added support for InterpLit node in RecDescent grammars
	- added cumulative effect for node attributes (patch by Diego
	  Zamboni)
	- changed the quoting rules again to make it easier to read
	  the dot files (idea by Diego Zamboni)
	- make add_edge() automatically add any nodes specified for
	  the edge that have not been previously added to stop the
	  Graph module complaining (patch by Diego Zamboni)
	- new 'node', 'edge', and 'graph' graph attributes to specify
	  global node, edge, and graph attributes (patch by Diego
	  Zamboni)
	- removed t/regex.t and documented that GraphViz::Regex may
	  not work on various perls
	- added GraphViz::Regex_YAPE module, another way to graph
	  a regular expression
