Month: 2025-05. Focused on delivering Priority-based Coordinated Leader Election feature for kubernetes/enhancements, introducing an optional Priority field in LeaseCandidateSpec to explicitly designate preferred leaders and improve control over leader assignment. Also updated documentation to reflect the new capability (README.md). This work improves leadership determinism and cluster stability in multi-node deployments. No major bugs fixed this month. Technologies demonstrated include API design for distributed systems, documentation, and contribution workflow. Overall business value: clearer leadership policy, safer failover, and smoother upgrades.
