NetworkX 1.4
============
Release date: 23 January 2011
New features
------------
- :mod:`k-shell,k-crust,k-corona <networkx.algorithms.core>`
- :mod:`read GraphML files from yEd <networkx.readwrite.graphml>`
- :mod:`read/write GEXF format files <networkx.readwrite.gexf>`
- :mod:`find cycles in a directed graph <networkx.algorithms.cycles>`
- :mod:`DFS <networkx.algorithms.traversal.depth_first_search>` and :mod:`BFS <networkx.algorithms.traversal.breadth_first_search>` algorithms
- :mod:`chordal graph functions <networkx.algorithms.chordal.chordal_alg>`
- :mod:`Prim's algorithm for minimum spanning tree <networkx.algorithms.mst>`
- :mod:`r-ary tree generator <networkx.generators.classic>`
- :mod:`rich club coefficient <networkx.algorithms.richclub>`
- NumPy matrix version of :mod:`Floyd's algorithm for all-pairs shortest path <networkx.algorithms.shortest_paths.dense>`
- :mod:`read GIS shapefiles <networkx.readwrite.nx_shp>`
- :mod:`functions to get and set node and edge attributes <networkx.classes.function>`
- and more, see https://networkx.lanl.gov/trac/query?status=closed&group=milestone&milestone=networkx-1.4
API changes
-----------
- :mod:`gnp_random_graph() <networkx.generators.random_graphs>` now takes a
directed=True|False keyword instead of create_using
- :mod:`gnm_random_graph() <networkx.generators.random_graphs>` now takes a
directed=True|False keyword instead of create_using
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.
