Mar 1, 2026March 2026 (2026-03) monthly summary for woodpecker-ci/woodpecker: Stabilized Kubernetes backend execution by introducing cancellation handling for goroutines and ensuring clean shutdown of work started by WaitStep and TailStep during cancellation. This reduces resource leaks, mitigates OOMKilled risks, and improves overall agent stability in Kubernetes-backed CI workflows. The work aligns with existing guidance to react to ctx.Done rather than relying on pod deletion events, strengthening the cancellation pattern and reliability of the runtime.
