Feb 1, 2026

February 2026 monthly summary focusing on Kubernetes repository hygiene, observability, and documentation. Delivered two key features: (1) Documentation cleanup and client-go references removal, reducing coupling and clarifying guidance in README and YAML files; (2) New Kubernetes metrics and related documentation updates, introducing metrics for stale sync handling in controllers and API server performance, and aligning documentation with accurate categorization. Major commits included removal of client-go references and a rebase/regenerate cycle for metrics work. These efforts improved maintainability, observability, and operational reliability across the kubernetes/kubernetes repository.
