Simple check list from AllenNLP repo: https://github.com/allenai/allennlp/blob/main/setup.py

To create the package for pypi.

1. Create the release branch named: v<RELEASE>-release, for example v4.19-release. For a patch release checkout the
   current release branch.

   If releasing on a special branch, copy the updated README.md on the main branch for the commit you will make
   for the post-release and run `make fix-repo` on the main branch as well.

2. Run `make pre-release` (or `make pre-patch` for a patch release) and commit these changes with the message:
   "Release: <VERSION>" and push.

3. Go back to the main branch and run `make post-release` then `make fix-repo`. Commit these changes with the
   message "v<NEXT_VERSION>.dev.0" and push to main.

# If you were just cutting the branch in preparation for a release, you can stop here for now.

4. Wait for the tests on the release branch to be completed and be green (otherwise revert and fix bugs)

5. On the release branch, add a tag in git to mark the release: "git tag v<VERSION> -m 'Adds tag v<VERSION> for pypi' "
   Push the tag to git: git push --tags origin v<RELEASE>-release

6. Have a core maintainer review and approve the deployment to pypi.
