First, update the version number in version.py using semantic versioning.
Tag your commit with the new version number. For example:
git tag -a v0.1.0 -m "v0.1.0"
Push the tag to GitHub:
git push origin v0.1.0
Install twine and install build:
pip install twine pip install build
Build the package:
python -m build
Upload the package to test.pypi.org:
twine upload --repository testpypi dist/*
Verify you can install it. Then, upload it to pypi.org:
twine upload dist/*
Again, verify it installs correctly. Then, finally, create a new release on GitHub.
