Pynauty 1.1.0 has been released.

Changes in this version:

  - Built with nauty27r3

  - Works with Python 3.7 - 3.10

  - Frank Bryce fixed the issue of misleadingly accepting multigraphs.

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.
