First, update the version number throughout the repo and push the change:
./tools/makever.py --version X.Y.Z
git commit -a -m "Update version"
git push
GitHub CI Actions are used to automatically build a draft package whenever a tag is pushed to repo:
git tag X.Y.Z
git push origin X.Y.Z
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
At this point, a GitHub Action will run that will download the new combined JSON file from the tag and update the global release with it.
