We released nixpkgs-review 3.0.0 recently.
One prominent feature is the support for using evaluation results directly from github actions
instead of having to run evaluation locally or rely on the slower ofborg results.
Thanks to @GaetanLepage for working on this.
To use this feature you however need to provide a GITHUB_TOKEN.
You can obtain one using the gh:
$ export GITHUB_TOKEN=$(gh auth token)
$ nixpkgs-review pr <pr_number>
We hope to integrate this tool better in future versions.
