 Migration Guides: Kilted Kaiju to Lyrical Luth
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
 This list summarizes important changes between Kilted Kaiju (previous) and Lyrical Luth (current) releases, where changes to user code might be necessary.
+
+
+effort_controllers
+*****************************
+* ``effort_controllers/JointGroupEffortController`` is deprecated. Use :ref:`forward_command_controller <forward_command_controller_userdoc>` instead by adding the ``interface_name`` parameter and set it to ``effort``. (`#1913 <https://github.com/ros-controls/ros2_controllers/pull/1913>`_).
+
+position_controllers
+*****************************
+* ``position_controllers/JointGroupPositionController`` is deprecated. Use :ref:`forward_command_controller <forward_command_controller_userdoc>` instead by adding the ``interface_name`` parameter and set it to ``position``. (`#1913 <https://github.com/ros-controls/ros2_controllers/pull/1913>`_).
+
+velocity_controllers
+*****************************
+*  ``velocity_controllers/JointGroupVelocityController`` is deprecated. Use :ref:`forward_command_controller <forward_command_controller_userdoc>` instead by adding the ``interface_name`` parameter and set it to ``velocity``. (`#1913 <https://github.com/ros-controls/ros2_controllers/pull/1913>`_).

 forward_command_controller
 ==========================
 
-This is a base class implementing a feedforward controller. Specific implementations of this base class can be found in:
+A selection of controllers that forward commands of different types.
 
-* :ref:`position_controllers_userdoc`
-* :ref:`velocity_controllers_userdoc`
-* :ref:`effort_controllers_userdoc`
+forward_command_controller and multi_interface_forward_command_controller
+#########################################################################
+Both controllers forward ``std_msgs::msg::Float64MultiArray`` to a set of interfaces, which can be parameterized as follows: While ``forward_command_controller/ForwardCommandController`` only claims a single interface type per joint (``joint[i] + "/" + interface_name``), the ``forward_command_controller/MultiInterfaceForwardCommandController`` claims the combination of all interfaces specified in the ``interface_names`` parameter (``joint[i] + "/" + interface_names[j]``).
 
 Hardware interface type
 -----------------------
 
-This controller can be used for every type of command interface.
+This controller can be used for every type of command interface, not only limited to joints.
