Oct 1, 2025October 2025 (ArduPilot/ardupilot) focused on stabilizing GCS telemetry for high-latency links. Implemented a targeted stability improvement by avoiding the initialization of MAVLink stream rates for high-latency connections, reducing spurious rate negotiations and improving connection reliability in remote or long-distance operations. This low-risk, well-scoped fix aligns with reliability and mission success goals and preserves normal behavior for standard latency links. Overall, the work enhances robustness of GCS communication under challenging network conditions, contributing to safer and more predictable missions.

Dec 1, 2024December 2024 — ArduPilot/ardupilot: Delivered two feature improvements that enhance autonomous rover navigation and tuning workflows, with direct business value in safety, precision, and configurability. Circle Mode Navigation now uses dynamic on-track thresholds and reduces the minimum circle radius to 0.1m, enabling tighter circle following and better performance in constrained environments. Rover QuickTune now supports a configurable minimum tuning speed via RTUN_SPEED_MIN and includes documentation updates to reflect usage. No major bugs fixed this month; the focus was on delivering impactful features with traceable commits and clear user documentation. These changes improve path fidelity, tuning efficiency, and deployment readiness for field operations.
