Changes since 2009.5.1

• Fixed a bug where the Show instance and read function for DotEdge had the from/to nodes the wrong way round. This was not immediately noticed since the Graph -> DotGraph functions created them the wrong way round, so for those users who only used these this was not apparent. Spotted by Neil Brown.

• Greatly improved Attribute usage: almost all attributes are now covered with allowed values.

• Extend DotGraph to include whether a graph is strict or not and if it has an ID. Also move the directedGraph field.

• Make "Dot" refer to the actual dot command and DotArrow refer to the ArrowType (rather than DotCmd and Dot as before).

• Make the Data.GraphViz.ParserCombinators module available to end users again, but not re-exported by Data.GraphViz; it has a warning message up the top not to be used. It is there purely for documentative purposes.

• Use extensible-exceptions so that base < 4 is once again supported.

• Follow the PVP rather than using dates for versions: http://www.haskell.org/haskellwiki/Package_versioning_policy

Changes since 2008.9.20:

• Support polyparse >= 1.1 (as opposed to < 1.3)

• Require base == 4.* (i.e. GHC 6.10.*) due to new exception handling.

• Include functions from Graphalyze-0.5 for running GraphViz commands, etc.

• Module re-organisation.

• The Data.GraphViz.ParserCombinators module is no longer available to end users.

• Improved Haddock documentation.

Changes since 2008.9.6

• Differentiate between undirected and directed graphs (previously only directed graphs were supported).

• Clustering support was added.
