If you run prek in GitHub CI, please try [`j178/prek-action@v2.0.0-beta.4`](https://github.com/j178/prek-action/releases/tag/v2.0.0-beta.4). The 2.0 beta series rewrites the action in TypeScript, adds semver range support for `prek-version`, and verifies downloaded prek archives with published SHA-256 checksums.

## Verifying GitHub Artifact Attestations

The artifacts in this release have attestations generated with GitHub Artifact Attestations. These can be verified by using the [GitHub CLI](https://cli.github.com/manual/gh_attestation_verify):
```sh
gh attestation verify <file-path of downloaded artifact> --repo j178/prek
```

You can also download the attestation from [GitHub](https://github.com/j178/prek/attestations) and verify against that directly:
```sh
gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>
```
