 * 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>`_).
