This release is now compatible with CPython (2.5 and 2.6), PyPy (1.2), Unladen-Swallow (2.6.1) and Jython (2.5.1). PyGraphviz is no more required, which improves the portability to Windows and MacOS X: SNAKES should now work out of the box if GraphViz is properly installed.

Various bugs have been fixed:

• fixed snakes.plugins.clusters.rename_node
• fixed snakes.nets.Flush.flow
• fixed an uncaught exception in snakes.data.MultiSet.__eq__ and snakes.data.Symbol.__eq__
• hopefully fixed LALR built in ABCD compiler
• fixed hash-related issues

Other changes include:

• moved PLY stuff to snakes.utils.abcd
• snakes.compyler has been completely replaced (PLY dependency removed)

Download  source release tarball here. Ubuntu packages will be available as soon as LauchPad will have finished to build them.

Update: a blocking bug related to empty reduce in __hash__ methods has been fixed, you should update your version (links above updated).
