Concise monthly summary for 2025-04 focusing on delivering business value and technical accomplishments across two repositories: Unleash/unleash and Unleash/unleash-edge.

March 2025 delivered measurable improvements across edge security, build reliability, observability, and product quality, enabling broader platform support and faster release cycles. Key features include advanced certificate-based client authentication with flexible formats, new IP allow/deny middleware for edge security with scoped enforcement, and modernization of CI/CD pipelines with updated toolchains and cross-target builds (including AArch64 support). Observability and reliability were strengthened via a new request timing middleware, Prometheus metric enhancements for precise latency visibility, and hardened TLS error handling. UI and code quality improvements in Unleash improved admin UX and maintainability, including an admin menu hook, strict null checks, and an ADR for logging levels. In the Java client, release automation and guardrail improvements were implemented to streamline releases and reduce risk of metric-related null errors.
