July 2025 — For pm4ml/connection-manager-api, delivered secure database connectivity, enhanced audit data integrity, and hardened security posture through dependency updates. Implemented SSL/TLS for MySQL with environment-driven config, certificate verification, and robust defaults, complemented by tests and config changes; fixed audit log to correctly associate actions with the responsible user ID, improving auditability and compliance; updated dependencies to stable versions and added a Grype vulnerability ignore rule to reduce false positives, improving build reliability and security posture. This work reduces risk in data access, enhances traceability, and supports ongoing stability of the connection manager API.
