Aug 1, 2025August 2025 monthly summary for PX4-Autopilot (PX4/PX4-Autopilot). Delivered a targeted stability improvement for altitude hold in auto fixed-bank loiter mode for fixed-wing aircraft. By adjusting altitude handling to NaN and height rate to 0.f, the system achieves more predictable altitude control during autonomous loiter, reducing altitude drift and enhancing mission reliability.

Dec 1, 2024December 2024: PX4-Autopilot RPM sensor enhancements delivered, enabling configurable pulses per revolution and safety filtering, along with a direct RPM input path. This improves measurement accuracy, robustness, and timestamp handling. A targeted refactor of the RPM control path was performed to simplify logic and improve maintainability, with safeguards to prevent publishing invalid data.

Nov 1, 2024November 2024 monthly summary for PX4-PX4-Autopilot: Implemented VTOL backward-transition braking controller with position feedback to stop at the current setpoint, reducing overshoot and improving landing stability. Braking logic was relocated to FlightTaskTransition to improve code organization and maintainability of the VTOL control path. The changes enhance safety-critical transition behavior in real-world landings and demonstrate solid integration of feedback-driven controls within the flight task framework. Commit 079b756f1b79866720c76417b8edd24547894703 documents the change (VTOL: Added position feedback to backward transition braking controller (#23731)).
