-# Release checklist
-# 1. Change the version in __init__.py and setup.py.
-# 2. Commit these changes with the message: "Release: Release"
-# 3. Add a tag in git to mark the release: "git tag RELEASE -m 'Adds tag RELEASE for PyPI'"
-#    Push the tag to git: git push --tags origin main
-# 4. Run the following commands in the top-level directory:
-#      python setup.py bdist_wheel
-#      python setup.py sdist
-# 5. Upload the package to the PyPI test server first:
-#      twine upload dist/* -r pypitest
-#      twine upload dist/* -r pypitest --repository-url=https://test.pypi.org/legacy/
-# 6. Check that you can install it in a virtualenv by running:
-#      pip install -i https://testpypi.python.org/pypi diffusers
-#      diffusers env
-#      diffusers test
-# 7. Upload the final version to the actual PyPI:
-#      twine upload dist/* -r pypi
-# 8. Add release notes to the tag in GitHub once everything is looking hunky-dory.
-# 9. Update the version in __init__.py, setup.py to the new version "-dev" and push to main.
