 ********************
 * The changes from `(PR #1694) <https://github.com/ros-controls/ros2_control/pull/1694>`__ will affect how the controllers will be loading the parameters. Defining parameters in a single yaml file and loading it to the controller_manager node alone will no longer work.
   In order to load the parameters to the controllers properly, it is needed to use ``--param-file`` option from the spawner. This is because the controllers will now set ``use_global_arguments`` from `NodeOptions <https://docs.ros.org/en/rolling/p/rclcpp/generated/classrclcpp_1_1NodeOptions.html#_CPPv4N6rclcpp11NodeOptions20use_global_argumentsEb>`__ to false, to avoid getting influenced by global arguments.
+* With (`#1683 <https://github.com/ros-controls/ros2_control/pull/1683>`_) the ``rclcpp_lifecycle::State & get_state()`` and ``void set_state(const rclcpp_lifecycle::State & new_state)`` are replaced by ``rclcpp_lifecycle::State & get_lifecycle_state()`` and ``void set_lifecycle_state(const rclcpp_lifecycle::State & new_state)``. This change affects controllers and hardware. This is related to (`#1240 <https://github.com/ros-controls/ros2_control/pull/1240>`_) as variant support introduces ``get_state`` and ``set_state`` methods for setting/getting state of handles.
