 * The ``ros2_control_node`` node now accepts the ``thread_priority`` parameter to set the scheduler priority of the controller_manager's RT thread (`#1820 <https://github.com/ros-controls/ros2_control/pull/1820>`_).
 * The ``ros2_control_node`` node has a new ``lock_memory`` parameter to lock memory at startup to physical RAM in order to avoid page faults (`#1822 <https://github.com/ros-controls/ros2_control/pull/1822>`_).
 * The ``ros2_control_node`` node has a new ``cpu_affinity`` parameter to bind the process to a specific CPU core. By default, this is not enabled. (`#1852 <https://github.com/ros-controls/ros2_control/pull/1852>`_).
+* The ``--controller-manager-call-timeout`` was added as parameter to the helper scripts ``spawner.py``. Useful when the CPU load is high at startup and the service call does not return immediately (`#1808 <https://github.com/ros-controls/ros2_control/pull/1808>`_).
