During February 2026, Manuel Muttoni enhanced the micronaut-projects/micronaut-core repository by enabling Authentication as a valid parameter in WebSocket event handlers. This feature allows user authentication information to be passed directly with WebSocket events, supporting secure and context-aware real-time messaging. Manuel approached the task with a focus on backend development and security, leveraging Java and WebSocket technologies to reinforce authentication context propagation throughout the system. The work addressed a core need for secure communication in event-driven architectures, and the implementation was delivered with traceable, collaborative code changes. No major bugs were reported, reflecting a focused and well-executed feature delivery.
