Month 2025-11 – OpenConext-engineblock focused on system stability and deployability improvements through configuration refactoring, environment-specific overrides, and dependency upgrades. The changes remove hardcoded parameters, clarify which configuration is active across environments, and centralize static values in framework.yaml to improve consistency and traceability. In parallel, Composer dependencies were updated to maintain security and compatibility. These efforts reduce deployment risk, improve environment parity (dev/stage/prod), and simplify future upgrades.
