PX4-Autopilot Main Release Notes

<script setup> import { useData } from 'vitepress' const { site } = useData(); </script>

This page is on a release branch, and hence probably out of date. See the latest version.

This contains changes to PX4 main branch since the last major release (PX v1.16).

::: warning PX4 v1.17 is in alpha/beta testing. Update these notes with features that are going to be in main (PX4 v1.18 or later) but not the PX4 v1.17 release. :::

Upgrade Guide

Other changes

Hardware Support

• TBD

Common

• Remote ID (Open Drone ID) in-flight failsafe: extended COM_ARM_ODID to also trigger a configurable failsafe action (Return, Land, or Terminate) if the Remote ID heartbeat is lost while airborne. Users previously on COM_ARM_ODID=2 retain the same arming behaviour; set to 3 or higher to enable the in-flight action. (PX4-Autopilot#27029)
• QGroundControl Bootloader Update via the SYS_BL_UPDATE parameter has been re-enabled after being broken for a number of releases. (PX4-Autopilot#25032: build: romf: fix generation of rc.board_bootloader_upgrade).
• Feature: Allow prioritization of manual control inputs based on their instance number in ascending or descending order. (PX4-Autopilot#25602: Ascending and descending manual control input priorities).

Control

• Added new flight mode(s): Altitude Cruise (MC), Altitude Cruise (FW). For fixed-wing the mode behaves the same as Altitude mode but you can disable the manual control loss failsafe. (PX4-Autopilot#25435: Add new flight mode: Altitude Cruise).

Estimation

• Added EKF2_POS_LOCK to force constant position fusion while landed, useful for vehicles relying on dead-reckoning sensors (airspeed, optical flow) that provide no aiding on the ground.

Sensors

• Add sbgECom INS driver (PX4-Autopilot#24137)
• Quick magnetometer calibration now supports specifying an arbitrary initial heading (PX4-Autopilot#24637)

Simulation

• SIH: Add option to set wind velocity (PX4-Autopilot#26467)

Debug & Logging

• Asset Tracking: Automatic tracking and logging of external device information including vendor name, firmware and hardware version, serial numbers. Currently supports DroneCAN devices. (PX4-Autopilot#25617)

Ethernet

• TBD

uXRCE-DDS / Zenoh / ROS2

• TBD

MAVLink

• TBD

RC

• Parse ELRS Status and Link Statistics TX messages in the CRSF parser.

Multi-Rotor

• Removed parameters MPC_{XY/Z/YAW}_MAN_EXPO and use default value instead, as they were not deemed necessary anymore. (PX4-Autopilot#25435: Add new flight mode: Altitude Cruise).
• Renamed MPC_HOLD_DZ to MAN_DEADZONE to have it globally available in modes that allow for a dead zone. (PX4-Autopilot#25435: Add new flight mode: Altitude Cruise).
