Project status
- The source appears to have resumed maintenance recently, with an upstream push on 2026-07-01 and a corresponding update to v4.0.0 on 2026-07-01, but it had a long gap since the last documented update (v3.0.2 in 2023).
- Update cadence looks sporadic rather than continuous, with a multi-year quiet period before the 2026-07-01 updates, followed by no additional updates shown after that date up to 2026-08-12.
