In April 2026, delivered a reliability improvement for file copying in nodejs/node by integrating an upstream libuv change that treats futimens() as a best-effort operation. This prevents timestamp-setting failures from aborting copy on file systems that don’t support timestamps (e.g., CIFS/SMB shares), leading to more robust file handling across environments. The change was applied via a cherry-picked libuv commit and aligns with upstream fixes, reducing copy-time failures in CI and deployment workflows while maintaining cross-platform compatibility. No new user-facing features; the work focuses on stability, reliability, and maintainability of core I/O operations.
