          body: |
            LoopStructural released a new minor version (${{ steps.latest.outputs.version }}).
            This bumps the `~=` pin in `requirements/embedded.txt` and
            `requirements/testing.txt` accordingly.

            Verify the `qgis-compat` CI job passes before merging.
