v0.3.0-alpha.21
Pre-release0.3.0-alpha.21 (2026-10-12)
Fixed
- runtime: recover cleanly after Docker engine restarts (6a3800c)
Upgrade notes
- Fixes controller startup when Steam mounts were nested inside a read-only ROM library with missing mountpoints. Steam peer mounts preserve relative library links and owned-game detection.
- Adds bounded recovery for confirmed Arr and Cleanuparr database startup failures after Docker engine restarts, including current-start file logs when Docker logging is disabled.
- Adds an optional read-only RomM staging folder without replacing or automatically scanning the active library. RomM retains read-write access to its active library and Steam folders for UI uploads; the controller's separate library views remain read-only unless its importer is enabled.
Use Update Stackarr or stackarr update app to pull the release and recreate the controller with the updated mount layout. A plain container restart does not change its configured bind mounts. This release does not require a database migration or move game files; keep existing backups and library-path settings.
Validation includes the full application tests, lint/type checks, a Linux AMD64 image smoke build, and a published ARM64 runtime check on macOS with OrbStack. Both published architecture manifests are verified in Docker Hub and GHCR. This remains an alpha release: report platform-specific issues with the version/digest, host OS, Docker runtime, and architecture using the platform test form.
