The existing action versions run on Node runtimes GitHub no longer supports, and set-output is deprecated.

• actions/checkout v2 → v7
• docker/setup-qemu-action v1 → v4
• docker/setup-buildx-action v1 → v4
• docker/login-action v1 → v4
• docker/build-push-action v2 → v7
• set-output → $GITHUB_OUTPUT

All inputs in use are unchanged in the new versions. Note that build-push-action v4+ attaches provenance attestations by default, which show up as an extra unknown/unknown entry in the image manifest.

Independent of #21; whichever merges second will need a trivial rebase on default.yml.

Declare the workflow's token permissions explicitly.

The GHCR login passes GITHUB_TOKEN, and the build pushes on non-PR events. Without a workflow-level permissions block, these operations depend on repository or organization defaults. A default without packages: write can block publishing, while a broader default can grant more access than this job needs.

Declare least-privilege GITHUB_TOKEN permissions.

This workflow logs in to GHCR with GITHUB_TOKEN and pushes images on non-PR runs, but it does not declare a permissions block. zizmor reports the resulting default permissions as excessive. Add contents: read and packages: write at the smallest applicable scope. GitHub documents these scopes for checkout and package publishing. (docs.github.com)
