Next Release
============
Release date: TBD
Supports Python 3.7, 3.8, and 3.9.
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 `gallery of examples
<https://networkx.org/documentation/latest/auto_examples/index.html>`_.
Please send comments and questions to the `networkx-discuss mailing list
<http://groups.google.com/group/networkx-discuss>`_.
Highlights
----------
This release is the result of X of work with over X pull requests by
X contributors. Highlights include:
- Dropped support for Python 3.6.
- NumPy, SciPy, Matplotlib, and pandas are now default requirements.
Improvements
------------
- [`#4319 <https://github.com/networkx/networkx/pull/4319>`_]
pagerank uses scipy by default now.
- [`#4317 <https://github.com/networkx/networkx/pull/4317>`_]
New ``source`` argument to ``has_eulerian_path`` to look for path starting at
source.
- [`#4640 <https://github.com/networkx/networkx/pull/4640>`_]
``prefix_tree`` now uses a non-recursive algorithm. The original recursive
algorithm is still available via ``prefix_tree_recursive``.
- [`#4659 <https://github.com/networkx/networkx/pull/4659>`_]
New ``initial_graph`` argument to ``barabasi_albert_graph`` and
``dual_barabasi_albert_graph`` to supply an initial graph to the model.
API Changes
-----------
- [`#4190 <https://github.com/networkx/networkx/pull/4190>`_]
Removed ``tracemin_chol``. Use ``tracemin_lu`` instead.
- [`#4216 <https://github.com/networkx/networkx/pull/4216>`_]
In `to_*_array/matrix`, nodes in nodelist but not in G now raise an exception.
Use G.add_nodes_from(nodelist) to add them to G before converting.
- [`#4360 <https://github.com/networkx/networkx/pull/4360>`_]
Internally `.nx_pylab.draw_networkx_edges` now always generates a
list of `matplotlib.patches.FancyArrowPatch` rather than using
a `matplotlib.collections.LineCollection` for un-directed graphs. This
unifies interface for all types of graphs. In
addition to the API change this may cause a performance regression for
large graphs.
- [`#4384 <https://github.com/networkx/networkx/pull/4384>`_]
Added edge_key parameter for MultiGraphs in to_pandas_edgelist
- [`#4466 <https://github.com/networkx/networkx/pull/4466>`_]
`relabel_nodes` used to raise a KeyError for a key in `mapping` that is not
a node in the graph, but it only did this when `copy` was `False`. Now
any keys in `mapping` which are not in the graph are ignored.
- [`#4573 <https://github.com/networkx/networkx/pull/4573>`_]
`label_propagation_communities` returns a `dict_values` object of community
sets of nodes instead of a generator of community sets. It is still iterable,
so likely will still work in most user code and a simple fix otherwise:
e.g., add `iter( ... )` surrounding the function call.
- [`#4545 <https://github.com/networkx/networkx/pull/4545>`_]
`prefix_tree` used to return `tree, root` but root is now always 0
instead of a UUID generate string. So the function returns `tree`.
- [`#4545 <https://github.com/networkx/networkx/pull/4545>`_]
The variable `NIL` ="NIL" has been removed from `networkx.generators.trees`
- [`#3620 <https://github.com/networkx/networkx/pull/3620>`_]
The function `naive_greedy_modularity_communities` now returns a
list of communities (like `greedy_modularity_communities`) instead
of a generator of communities.
Deprecations
------------
- [`#4238 <https://github.com/networkx/networkx/pull/4238>`_]
Deprecate ``to_numpy_matrix`` and ``from_numpy_matrix``.
- [`#4279 <https://github.com/networkx/networkx/pull/4279>`_]
Deprecate ``networkx.utils.misc.is_iterator``.
Use ``isinstance(obj, collections.abc.Iterator)`` instead.
- [`#4280 <https://github.com/networkx/networkx/pull/4280>`_]
Deprecate ``networkx.utils.misc.is_list_of_ints`` as it is no longer used.
See ``networkx.utils.misc.make_list_of_ints`` for related functionality.
- [`#4281 <https://github.com/networkx/networkx/pull/4281>`_]
Deprecate ``read_yaml`` and ``write_yaml``.
- [`#4282 <https://github.com/networkx/networkx/pull/4282>`_]
Deprecate ``read_gpickle`` and ``write_gpickle``.
- [`#4298 <https://github.com/networkx/networkx/pull/4298>`_]
Deprecate ``read_shp``, ``edges_from_line``, and ``write_shp``.
- [`#4319 <https://github.com/networkx/networkx/pull/4319>`_]
Deprecate ``pagerank_numpy``, ``pagerank_scipy``.
- [`#4355 <https://github.com/networkx/networkx/pull/4355>`_]
Deprecate ``copy`` method in the coreview Filtered-related classes.
- [`#4384 <https://github.com/networkx/networkx/pull/4384>`_]
Deprecate unused ``order`` parameter in to_pandas_edgelist.
