 * The ``--controller-type`` or ``-t`` spawner arg is removed. Now the controller type is defined in the controller configuration file with ``type`` field (`#1639 <https://github.com/ros-controls/ros2_control/pull/1639>`_).
 * The ``--namespace`` or ``-n`` spawner arg is deprecated. Now the spawner namespace can be defined using the ROS 2 standard way (`#1640 <https://github.com/ros-controls/ros2_control/pull/1640>`_).
 * Added support for the wildcard entries for the controller configuration files (`#1724 <https://github.com/ros-controls/ros2_control/pull/1724>`_).
+* The spawner now supports the ``--controller-ros-args`` argument to pass the ROS 2 node arguments to the controller node to be able to remap topics, services and etc (`#1713 <https://github.com/ros-controls/ros2_control/pull/1713>`_).
 * The spawner now supports parsing multiple ``-p`` or ``--param-file`` arguments, this should help in loading multiple parameter files for a controller or for multiple controllers (`#1805 <https://github.com/ros-controls/ros2_control/pull/1805>`_).
 * ``--switch-timeout`` was added as parameter to the helper scripts ``spawner.py`` and ``unspawner.py``. Useful if controllers cannot be switched immediately, e.g., paused simulations at startup (`#1790 <https://github.com/ros-controls/ros2_control/pull/1790>`_).
 * ``ros2_control_node`` can now handle the sim time used by different simulators, when ``use_sim_time`` is set to true (`#1810 <https://github.com/ros-controls/ros2_control/pull/1810>`_).
