 ### Improved ROS 2 Interface via uXRCE-DDS
 
-We updated the ROS 2 interface, replacing [Fast-RTPS](https://docs.px4.io/v1.13/en/middleware/micrortps.html) with [uXRCE-DDS](../ros2/user_guide.md), resulting in an improved experience across the board.

 The change also avoids the need for `_rtps` build targets, enabling the interface on even more targets by default.
