December 2025: Implemented Gateway Development Mode Configuration in freifunk-berlin/bbb-configs. Added a development flag to gateway configuration and updated templates to conditionally include gateways based on their development status, enabling safer testing and flexible network setup. This change reduces deployment risk in test environments, accelerates experimentation, and enhances configurability for operators. No major bugs reported this month; focus remained on delivering a robust, maintainable feature with clear rollback. Demonstrates strong configuration management, templating, and Git-based collaboration to support scalable network operations.
