ArduPilot 4.7.1 remains the stable maintenance baseline across vehicle types

ArduPilot's current release page lists 4.7.1 for Copter, Plane, Rover, Sub, Tracker and Periph, with the maintenance line released in early September.

A synchronized stable family matters for builders combining autopilot, peripherals and companion systems across different vehicle types.

Archive parameters before upgrading and check board-specific notes. Mature autopilot firmware still needs conservative first-flight validation after a version change.
