- Update VERSION to 5.0.0-rc.1
- Add prerelease detection to create-release workflow
- Mark RC releases as prereleases on GitHub (not 'latest')
- Update publish-docker workflow to skip :latest tag for RCs
- Support -rc.N, -alpha.N, and -beta.N version suffixes
- Preflight builds multi-arch images to staging tags on GHCR
- Publish workflow just retags staging → final (no rebuild)
- Reduces publish time from ~10min to ~1min
Docker images now build only after release is published, not during
the draft creation phase. This prevents users from getting updates
before the release is reviewed and approved.
