Making a release

Note

VERSION needs to be formatted following the v{major}.{minor}.{patch} convention. We need to follow this convention to be able to retrieve versioned scripts.

Major/Minor Release

1. Ensure your local repository is up to date with the upstream repository

git checkout main
git pull origin main

Warning

Do not merge other pull requests into main until the release is done. This is to ensure that the release is stable and does not include any untested changes. Announce internally (#trl-internal) to other maintainers that you are doing a release and that they must not merge PRs until the release is done.

2. Create a release branch from main

git checkout -b release-v{major}.{minor}

3. Change the version in the following files

  • .github/workflows/tests_latest.yml:

    - with: { ref: v{major}.{minor-1}-release }
+ with: { ref: v{major}.{minor}-release }

  • CITATION.cff

    - version: '{major}.{minor-1}'
+ version: '{major}.{minor}'

  • VERSION

    - {major}.{minor}.0.dev0
+ {major}.{minor}.0

4. Commit and push these changes

git add .github/workflows/tests_latest.yml CITATION.cff VERSION
git commit -m 'Release: {major}.{minor}'
git push origin release-v{major}.{minor}

5. Create a pull request

from release-v{major}.{minor} to main, named Release: v{major}.{minor}, wait for tests to pass, and request a review.

6. Once the pull request is approved, merge it into main

It will automatically publish the new version of the package on PyPI.

7. Add a tag in git to mark the release

git checkout main
git pull origin main
git tag -a v{major}.{minor}.0 -m 'Adds tag v{major}.{minor}.0 for PyPI'
git push origin v{major}.{minor}.0

8. Create a branch v{major}.{minor}-release for future patch releases

git checkout -b v{major}.{minor}-release
git push origin v{major}.{minor}-release

This ensures that future patch releases (v{major}.{minor}.1, v{major}.{minor}.2, etc.) can be made separately from main.

9. Create a GitHub Release

  1. Go to the repo’s releases section on GitHub.
  2. Click Draft a new release.
  3. Select the v{major}.{minor}.0 tag you just created in step 7.
  4. Add a title (v{major}.{minor}.0) and a short description of what’s new.
  5. Click Publish Release.

10. Bump to dev version

  1. Create a branch bump-dev-version-{major}.{minor+1} from main and checkout to it.
git checkout -b bump-dev-version-{major}.{minor+1}
  1. Change the version in file VERSION:
- {major}.{minor}.0
+ {major}.{minor+1}.0.dev0
  1. Commit and push these changes
git add VERSION
git commit -m '⬆️ Bump dev version'
git push origin bump-dev-version-{major}.{minor+1}

  1. Create a pull request from bump-dev-version-{major}.{minor+1} to main, named ⬆️ Bump dev version, and request urgent review.

  2. Once the pull request is approved, merge it into main.

  3. The codebase is now ready for the next development cycle, inform the team in the #trl-internal channel.

Making a patch release

1. Ensure your local repository is up to date with the upstream repository

git checkout v{major}.{minor}-release
git pull origin main

2. Cherry-pick the changes you want to include in the patch release

git cherry-pick <commit-hash-0>
git cherry-pick <commit-hash-1>
...

3. Change the version in the file VERSION

- {major}.{minor}.{patch-1}
+ {major}.{minor}.{patch}

4. Commit and push these changes

git add VERSION
git commit -m 'Release: {major}.{minor}.{patch}'
git push origin v{major}.{minor}-release

5. Wait for the CI to pass

The CI will automatically publish the new version of the package on PyPI.

6. Add a tag in git to mark the release

git tag -a v{major}.{minor}.{patch} -m 'Adds tag v{major}.{minor}.{patch} for PyPI'
git push origin v{major}.{minor}.{patch}

7. Create a GitHub Release

  1. Go to the repo’s releases section on GitHub.
  2. Click Draft a new release.
  3. Select the v{major}.{minor}.{patch} tag you just created in step 7.
  4. Add a title (v{major}.{minor}.{patch}) and a short description of what’s new.
  5. Click Publish Release.
