Drop Python 3.9 support after EoL #1002

shalini9894 · 2025-11-21T21:14:01Z

Update classifiers, python_requires, CI workflows, tox envs, and release notes to require Python 3.10+

This PR removes support for Python 3.9 now that it has reached EoL.

Changes:

Update setup.py classifiers to remove Programming Language :: Python :: 3.9.
Set python_requires to >=3.10.
Update GitHub Actions workflows (main.yml, deploy-code.yml) to stop testing/building on 3.9 and use 3.10+.
Update tox.ini envlist to drop the py39 environment.
Add a release note explaining that Python 3.9 is no longer supported and the minimum required version is now 3.10.

Fixes #991

Update classifiers, python_requires, CI workflows, tox envs, and release notes to require Python 3.10+

The CI config requires the Python version to be specified as a string, eg '3.10' (see suggestion comments), otherwise it automatically reads 3.1, which is what is being run by CI in some instances. Once this is fixed, the rest of the PR looks good to go. Thanks for this contribution!

I have applied all the suggestions, and 3.10 is now consistently quoted in the workflows.

Hi @edoaltamura I implemented the suggestions. Please let me know if there is any changes required. Thank you.

@shalini9894 thanks! The changes fixed the py version in CI tests. The coverage files are not matching though somehow - see below.
