+1. Update `SERIAL` in `bin/package-version` to add a post-release tag to the upstream uWSGI version
 2. Run `make update` to update uWSGI. uWSGI should be pinned to the [latest release](https://github.com/unbit/uwsgi/releases).
 3. Push changes and wait for GH Actions to finish.
 4. If GH Actions succeeds, tag the commit with the uWSGI version number and push the tag.
