NetworkX 2.0b1 released

Hi All,

I am happy to announce the **beta** release of NetworkX 2.0! NetworkX
is a Python package for the creation, manipulation, and study of the
structure, dynamics, and functions of complex networks.

This release supports Python 2.7 and 3.4-3.6 and contains many new
features. This release is the result of over two years of work with
over 600 pull requests by 85 contributors. We have made **major
changes** to the methods in the Multi/Di/Graph classes and before the
2.0 release we need feedback on those changes. If you have code that
imports networkx, please take some time to check that you are able to
update your code to work with the new release.

Please see the draft of the 2.0 release announcement:
In particular, we would like feedback on the migration guide from 1.X to 2.0:

Since it is a beta release, pip won't automatically install it. So
  $ pip install networkx
still installs networkx-1.11 still. But
  $ pip install --pre networkx
will install networkx-2.0b1. If you already have networkx installed
then you need to do
  $ pip install --pre --upgrade networkx

issue `here <>`_.

Best regards,
