Changes:
In addition, Version 2.0 now uses dynamic memory allocation which allows nauty to work on graphs on any size.
New Features:
The function GenerateGraphs gives access to the graph generation program written by B. McKay. This feature is only available on Unix platforms as graphs are generated (and read from) within a Unix pipe.
The graph generation program allows users to generate any isomorph-free collection of graphs responding to several criteria like, among others, the connectedness of the graphs, or whether they are 3 or 4-cycle free.
