ArduPilot 4.7.1 stable releases consolidate fixes across air and ground vehicles
Recent context from early September: ArduPilot released 4.7.1 stable builds for Copter, Plane, Rover, Sub and Tracker. Copter's release notes include a fix to speed, velocity and acceleration handling for climbing Arc waypoints in Auto mode, along with additional board support and other maintenance changes.

Point releases often contain the navigation and hardware-support fixes that determine whether a new major branch is ready for operational fleets.
Review the vehicle-specific release notes rather than assuming all 4.7.1 builds contain the same changes. Mission-heavy aircraft should replay representative Auto missions in simulation or controlled testing before rolling the update across a fleet.
