## Upgrade Guide

## Other changes

### Hardware Support

- **[New Hardware]** boards: [MicoAir743-Lite FC](../flight_controller/micoair743-lite.md) <!-- CHECK is this version and add PR link (or fix up doc version tag and move this) -->
- **[New Hardware]** boards: [RadiolinkPIX6 FC](../flight_controller/radiolink_pix6.md) <!-- CHECK is this version and add PR! -->
- **[New Hardware]** boards: [AP-H743-R1 FC](../flight_controller/x-mav_ap-h743r1.md) <!-- CHECK is this version and add PR! -->

<!--

### Common

- [QGroundControl Bootloader Update](../advanced_config/bootloader_update.md#qgc-bootloader-update-sys-bl-update) via the [SYS_BL_UPDATE](../advanced_config/parameter_reference.md#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](https://github.com/PX4/PX4-Autopilot/pull/25032)).
-->

### 제어

<!--

- Added new flight mode(s): [Altitude Cruise (MC)](../flight_modes_mc/altitude_cruise.md), 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](https://github.com/PX4/PX4-Autopilot/pull/25435)).

-->

- <Badge type="warning" text="Experimental" /> [MC Neural Network Module](../advanced/neural_networks.md)

### Estimation

- TBD

<!--

### Sensors

- Add [sbgECom INS driver](../sensor/sbgecom.md) ([PX4-Autopilot#24137](https://github.com/PX4/PX4-Autopilot/pull/24137))
- Quick magnetometer calibration now supports specifying an arbitrary initial heading ([PX4-Autopilot#24637](https://github.com/PX4/PX4-Autopilot/pull/24637))

-->

### 시뮬레이션

- Overhaul rover simulation:
  - Add synthetic differential rover model: [PX4-gazebo-models#107](https://github.com/PX4/PX4-gazebo-models/pull/107)
  - Add synthetic mecanum rover model: [PX4-gazebo-models#113](https://github.com/PX4/PX4-gazebo-models/pull/113)
  - Update synthetic ackermann rover model: [PX4-gazebo-models#117](https://github.com/PX4/PX4-gazebo-models/pull/117)

- [Simulation-in-Hardware (SIH)](../sim_sih/index.md#compatibility) <!-- Listed in https://docs.px4.io/main/en/sim_sih/#compatibility : Check the PRs -->
  - New simulation: MC Hexacopter X
  - New simulation: Ackermann Rover

### Debug & Logging

- TBD

### Ethernet

- TBD

### uXRCE-DDS / Zenoh / ROS2

- [PX4 ROS 2 Interface Library](../ros2/px4_ros2_control_interface.md) support for [Fixed Wing lateral/longitudinal setpoint](../ros2/px4_ros2_control_interface.md#fixed-wing-lateral-and-longitudinal-setpoint-fwlaterallongitudinalsetpointtype) (`FwLateralLongitudinalSetpointType`) and [VTOL transitions](../ros2/px4_ros2_control_interface.md#controlling-a-vtol). ([PX4-Autopilot#24056](https://github.com/PX4/PX4-Autopilot/pull/24056)).
- [UXRCE_DDS: Simple index based namespace (UXRCE_DDS_NS_IDX)](../middleware/uxrce_dds.md#customizing-the-namespace)
- [Zenoh (PX4 ROS 2 rmw_zenoh)](../middleware/zenoh.md)

### 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](https://github.com/PX4/PX4-Autopilot/pull/25435)).
- 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](https://github.com/PX4/PX4-Autopilot/pull/25435)).
-->

### 수직이착륙기(VTOL)

- TBD

### Fixed-wing

- [Fixed Wing Takeoff mode](../flight_modes_fw/takeoff.md) will now keep climbing with level wings on position loss.
  A target takeoff waypoint can be set to control takeoff course and loiter altitude. ([PX4-Autopilot#25083](https://github.com/PX4/PX4-Autopilot/pull/25083)).
- Automatically suppress angular rate oscillations using [Gain compression](../features_fw/gain_compression.md). ([PX4-Autopilot#25840: FW rate control: add gain compression algorithm](https://github.com/PX4/PX4-Autopilot/pull/25840))

### 탐사선

- Removed deprecated rover module ([PX4-Autopilot#25054](https://github.com/PX4/PX4-Autopilot/pull/25054)).
- Add support for [Apps & API](../flight_modes_rover/api.md) including [Rover Setpoints](../ros2/px4_ros2_control_interface.md#rover-setpoints) ([PX4-Autopilot#25074](https://github.com/PX4/PX4-Autopilot/pull/25074), [PX4-ROS2-Interface-Lib#140](https://github.com/Auterion/px4-ros2-interface-lib/pull/140)).
- Update [rover simulation](../frames_rover/index.md#simulation) ([PX4-Autopilot#25644](https://github.com/PX4/PX4-Autopilot/pull/25644)) (see [Simulation](#simulation) release note for details).

### ROS 2

- TBD
