   ROS2_control in Lyrical Luth: what's new

   This update removes deprecated handle and export APIs, introduces new data types for handles including float32 and integer variants, adds flexible interface configuration types like INDIVIDUAL_BEST_EFFORT, and updates joint_trajectory_controller behavior to support trajectory replacement and deceleration on cancel. The post outlines breaking changes such as the removal of action_execution_timeout and the deprecation of specific group controllers in favor of forward_command_controller, alongside new features like positions_upsampling for learned policies and improved odometry setting services for mobile robots.
