November 2024 delivered notable UX and protocol improvements across mavlink/qgroundcontrol and Auterion/mavlink. Key features include UI-driven gimbal control with configurable sensitivity and GimbalIndicator UI polish; multi-GCS indicators and settings UI with new assets and icons; and a multi-GCS prototype with protocol refinements to ease adoption. A critical MAVLink ID conflict was resolved by updating OPERATOR_CONTROL to 32100 to maintain compatibility with ArduPilot. These efforts enhance operator control, multi-GCS feedback, and cross-repo interoperability, laying groundwork for broader multi-GCS usage and faster onboarding for customers.
