Spitfire 0.5.9 release notes
Released: 2026-09-30
- Runners installed without Docker (systemd, the Windows service) update themselves: 'Update' next to an older runner on the Runners page ('Update all' when there are several). The runner downloads the new release from the controller over the gRPC port, checks Spitfire's signature itself, accepts nothing unsigned or older, and restarts; a runner in a run is not updated.
- Existing runners installed without Docker get this after running their install command once more. Docker and Kubernetes runners keep updating with their image.
Updating
Your installation tells you about a new release itself: admins see its notes and the update command for that installation at the top of the UI. The command backs up the database first and keeps the settings (Updating). You can also follow new releases with the RSS feed.
