Version 1.8 notes and API changes

This page reflects API changes from networkx-1.7 to networkx-1.8.

Please send comments and questions to the networkx-discuss mailing list: http://groups.google.com/group/networkx-discuss .

• Laplacian functions now all return matrices. To get a numpy array from a matrix use L = nx.laplacian_matrix(G).A
• is_directed_acyclic_graph() now returns false on undirected graphs (instead of raising exception)
• cycles returned from simple_cycles() do not include repeated last node
