Apr 1, 2026April 2026 — Woodpecker CI: Code Quality and Logging Cleanliness improvements and SSE streaming stability fixes. Delivered a feature to streamline logging by removing unnecessary dev/test outputs, and fixed a panic in SSE stream handlers due to sends on closed channels; introduced synchronization to handle concurrent disconnections, improving streaming reliability. These changes reduce noise, prevent runtime panics, and boost overall CI streaming experience.

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.

Oct 1, 2025October 2025: Implemented a critical robustness fix in woodpecker-ci/woodpecker by addressing a panic in injectSecretRecursive when encountering nil values. Added regression tests to cover complex types with nil values, ensuring stability across secret injection paths. The change reduces production risk and improves reliability of pipelines that depend on secret handling.
