tox.ini:3

• Python 3.13 is not yet released as a stable version. Including py313 in the test matrix may cause CI failures. Consider removing py313 until Python 3.13 is officially released.

envlist = py38, py39, py310, py311, py312, py313

.github/workflows/tox.yml:18

• Python 3.13 is not yet available in GitHub Actions runners. This will cause the CI workflow to fail when trying to set up Python 3.13. Remove '3.13' from the matrix until it's officially supported.
