First, update the version number throughout the repo and add the tag:
./version.sh X.Y.Z
Verify things have gone well and then push the change and tag:
git commit -a -m "Update version"
git push
git tag X.Y.Z
git push origin X.Y.Z
GitHub CI Actions are used to automatically build a draft package whenever a tag is pushed to repo.
This will generate a draft release with a bulleted-list of git changes.
Edit the list and title as desired, then use the Publish button on the web interface to publish the release
