## Release process
This repository is configured for [`release-plz`](https://release-plz.dev/).
- Push regular changes to `main`.

- Merging that PR publishes unpublished crates and creates git tags and GitHub releases.
The release workflow expects a `CARGO_REGISTRY_TOKEN` secret with publish access to crates.io.
