This presentation gives an overview of the many new features added to the micro-ROS client library and middleware in the last months. In particular, we demonstrate (1.) the use of Micro XRCE-DDS interface for custom transports, (2.) the micro-ROS diagnostics package and the integration with ROS 2 diagnostics, (3.) and the worker concept for execution management in the C client library rclc.
