Feb 1, 2026February 2026 monthly summary for the marimo-team/marimo project focusing on stability and reliability of real-time session handling. The primary effort this month was a critical bug fix to WebSocket session TTL behavior, ensuring an actively used session is not terminated when a new consumer reconnects to the same session. Implemented safety checks in the WebSocketHandler to verify connection state before closing a session, reducing accidental disruptions for connected clients.
