+
+For code owners who wish to publish a release, make sure to follow these guidelines:

+1. Merge a PR that edits `pyproject.toml` to specify the new semver version.
+2. From the updated `main` branch, make a new tag with `git tag vX.Y.Z`.
+3. Push that tag to the remote repository with `git push --tags`.
+4. Go to the `releases` tab in Github and add the new tag as a release.
+5. Click the "Generate Release Notes" button to generate release notes.
+6. Add a brief summary under the "What's Changed" heading and create a "PRs" heading for the generated list of "PRs".
