 Pushing the tag triggers the [Release workflow](.github/workflows/release.yml), which creates a GitHub release using the matching `## vX.Y.Z` section of [CHANGELOG.md](CHANGELOG.md) as the release notes. Add the changelog entry before pushing the tag, otherwise the release falls back to autogenerated notes.
