1.17.0

Released: October 11, 2025

• [change] [tests] The top-level test runner has been changed to use nox, adding a noxfile.py as well as some included modules. The tox.ini file remains in place so that tox runs will continue to function in the near term, however it will be eventually removed and improvements and maintenance going forward will be only towards noxfile.py.

• [change] [general] The minimum Python version is now 3.10, as Python 3.9 is EOL.
