API Changes
Returning dictionaries

Several of the algorithms and the degree() method now return dictionaries keyed
by node instead of lists. In some cases there was a with_labels keyword which is
no longer necessary. For example,

>>> G=nx.Graph()
>>> G.add_edge('a','b')
>>> G.degree() # returns dictionary of degree keyed by node
{'a': 1, 'b': 1}

Asking for the degree of a single node still returns a single number

>>> G.degree('a')
1

The following now return dictionaries by default (instead of lists) and the
with_labels keyword has been removed:

        * Graph.degree(), MultiGraph.degree(), DiGraph.degree(),
DiGraph.in_degree(), DiGraph.out_degree(), MultiDiGraph.degree(),
MultiDiGraph.in_degree(), MultiDiGraph.out_degree().
        * clustering(), triangles()
        * node_clique_number(), number_of_cliques(), cliques_containing_node()
        * eccentricity()

The following now return dictionaries by default (instead of lists)

        * pagerank()
        * hits()

Adding nodes

add_nodes_from now accepts (node,attrdict) two-tuples

>>> G=nx.Graph()
>>> G.add_nodes_from([(1,{'color':'red'})])

Examples

        * Mayvi2 drawing
        * Blockmodel
        * Sampson?s monastery
        * Ego graph

Bug fixes

        * Support graph attributes with union, intersection, and other graph
operations
        * Improve subgraph speed (and related algorithms such as
connected_components_subgraphs())
        * Handle multigraphs in more operators (e.g. union)
        * Handle double-quoted labels with pydot
        * Normalize betweeness_centrality for undirected graphs correctly
        * Normalize eigenvector_centrality by l2 norm
        * read_gml() now returns multigraphs
