+
+- Increment the version number using [the `hatch version` command](https://hatch.pypa.io/latest/version/#updating).
+- Commit the changes and create a PR.

+  - Set the tag name as `vX.Y.Z`, matching the version reported by hatch.
+  - Write some release notes (possibly using the `Generate release notes` button).
+  - Publish the release!
+- Sit back and relax while the release gets built and published.
+- Check that the new version is available on [PyPI](https://pypi.org/project/pyorderly/#history).
