Release checklist

Jazzband guidelines: https://jazzband.co/about/releases

Get main to the appropriate code release state. GitHub Actions should pass on main.
Edit release draft, adjust text if needed: https://github.com/jazzband/prettytable/releases
Check next tag is correct, amend if needed
Publish release
Once GitHub Actions has built and uploaded distributions, check files at Jazzband and release to PyPI
Check installation:

pip uninstall -y prettytable
pip install -U prettytable
python3 -c "import prettytable; print(prettytable.__version__)"
