tag versions

greetings,

it would be nice if you could `git tag` the versions (i.e. when you update the version in pyproject.toml, etc), and push them (`git push --tags`), so it's possible to track versions without needing to use specific commit hashes.

Start by inspecting pyproject.toml and the project’s current version-update process. Check how the version is released, then ensure each updated version has a corresponding Git tag that is pushed with the release; done means versions can be tracked by tags rather than commit hashes.
