doc/release/release_2.8.rst
Release date: 9 April 2022
Supports Python 3.8, 3.9, and 3.10
NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.
For more information, please visit our website <https://networkx.org/>_
and our :ref:gallery of examples <examples_gallery>.
Please send comments and questions to the networkx-discuss mailing list <http://groups.google.com/group/networkx-discuss>_.
This release is the result of over five weeks of work with 48 pull requests by
18 contributors. This is the last release before NetworkX 3.0. For a preview of the
upcoming 3.0 release, please see the draft of our
migration guide <https://networkx.org/documentation/latest/release/migration_guide_from_2.x_to_3.0.html>_
for people moving from 2.X to 3.0.
Correction to the treatment of directed graphs for average_neighbor_degree
which used to sum the degrees of outgoing neighbors only but then divide by
the number of "in" or "out" or "in+out" neighbors. So it wasn't even an average.
The correction makes it an average degree of whatever population of neighbors
is specified by source = "in" or "out" or "in+out".
For example:
>>> G = nx.path_graph(3, create_using=nx.DiGraph)
>>> print(nx.average_neighbor_degree(G, source="in", target="in"))
{0: 0.0, 1: 1.0, 2: 1.0}
This used to produce {0: 0.0, 1: 1.0, 2: 0.0}
Note: node 0 and 2 were treated nonsensically.
Node 0 had calculated value 1/0 which was converted to 0.
(numerator looking at successors while denominator counting predecessors)
Node 2 had caluated value 0/1 = 0.0 (again succs on top, but preds in bottom)
Now node 0 has calculated value 0.0/0 which we treat as 0.0. And node 2 has calculated value 1/1 = 1.0. Both handle the same nbrhood on top and bottom.
#5394 <https://github.com/networkx/networkx/pull/5394>_]
The function min_weight_matching no longer acts upon the parameter maxcardinality
because setting it to False would result in the min_weight_matching being no edges
at all. The only reasonable option is True. The parameter will be removed completely in v3.0.#5227 <https://github.com/networkx/networkx/pull/5227>_]
Deprecate the n_communities parameter name in greedy_modularity_communities
in favor of cutoff.#5422 <https://github.com/networkx/networkx/pull/5422>_]
Deprecate extrema_bounding. Use the related distance measures with
usebounds=True instead.#5427 <https://github.com/networkx/networkx/pull/5427>_]
Deprecate dict_to_numpy_array1 and dict_to_numpy_array2 in favor of
dict_to_numpy_array, which handles both.#5428 <https://github.com/networkx/networkx/pull/5428>_]
Deprecate utils.misc.to_tuple.to_tuple (#5430)
