 Currently we release in a semi-automated way:
 
+- PR & merge an updated [Changelog](CHANGELOG.md).
 - Run `cargo release --no-push --no-publish --no-confirm -x patch` locally to
   bump the versions, and PR the change on a branch
 - After merging, go to [Draft a new
   release](https://github.com/prql/prql/releases/new), write up release notes,
   select a new tag to be created, and hit the "Publish" button.
 - From there, all packages are published automatically based on our [release
   workflow](.github/workflows/release.yaml).
+- Add in the sections for a new Changelog:

 We may make this more automated in future; e.g. automatic changelog creation.
