So, having a nice PR title will not only look nice in GitHub, but also in the release notes. 📝

## Add Labels to PRs

The same GitHub Action [latest-changes](https://github.com/tiangolo/latest-changes) uses one label in the PR to decide the section in the release notes to put this PR in.

Make sure you use a supported label from the [latest-changes list of labels](https://github.com/tiangolo/latest-changes#using-labels):
