Version 1.4 notes and API changes

We have made some API changes, detailed below, to add clarity. This page reflects changes from networkx-1.3 to networkx-1.4. For changes from earlier versions to networkx-1.0 see Version 1.0 API changes.

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

Algorithms changed

Shortest path

astar_path(), astar_path_length(), shortest_path(), shortest_path_length(),

bidirectional_shortest_path(), dijkstra_path(), dijkstra_path_length(),

bidirectional_dijkstra()

These algorithms now raise an exception when a source and a target are specified and no path exist between these two nodes. The exception is a NetworkXNoPath exception.
