February 2025 monthly summary: This sprint delivered key API governance and observability enhancements across wso2/apk and wso2/product-apim-tooling. Key features delivered include GraphQL API integration and stability improvements in the go-enforcer, API routing/scope/versioning enhancements, API definition handling improvements for gRPC/GraphQL, metrics and observability via Prometheus-ready metrics in gateway enforcer, and a multi-environment JWT requirements flag to support flexible deployments. Major bugs fixed include a custom rate-limiting metadata namespace bug (with organization ID as metadata), scope validation bug, semantic versioning regex matching issue, and API definition go-integration test failures. The combination of these changes improves API reliability, policy enforcement precision, and operational visibility, enabling safer deployments and faster iteration. In addition, operational maintenance included renewing the internal key certificate used by the APIM APK issuer to maintain secure operation. Technologies demonstrated: Go, GraphQL, gRPC, API routing and versioning, semantic versioning, Prometheus metrics, testing, multi-environment deployment strategies, and observability best practices.
