[Nauty] pynauty-1.0.2 released

[Peter Dobsan]

Announcement:

pynauty-1.0.2 built with nauty27r1 has been released.

Changes in this version:

  - Sam Morley-Short added a new function `canon_label(g)` to find the
    canonical labeling of vertices.

Pynauty can be used to compare graphs for isomorphism and to determine
their automorphism group in a Python programming environment.  Pynauty
is a Python/C extension module using library components from the Nauty
package by Brendan McKay.

It is available from PyPi and the sources are on GitHub.
You can install it using pip:

    pip install --upgrade pynauty

Many binary wheels are provided for recent Linux and macOS systems.
When your system is not compatible with any of the provided binary
wheels `pip` attempts to build the wheel of the extension module on your
local machine.

The package comes with HTML documentation and a comprehensive test suit.
