-Foxy to Galactic
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-hardware_interface
-**************************************
-Between Foxy and Galactic we made substantial changes to the interface of hardware components to enable management of their lifecycle.
-The following list shows a set of quick changes to port existing hardware components to Galactic:
-
-1. Rename ``configure`` to ``on_init`` and change return type to ``CallbackReturn``
-
-2. If using BaseInterface as base class then you should remove it. Specifically, change:
-
-  .. code-block:: c++
-
-    hardware_interface::BaseInterface<hardware_interface::[Actuator|Sensor|System]Interface>
-
-  to
-
-  .. code-block:: c++
-
-    hardware_interface::[Actuator|Sensor|System]Interface
-
-3. Remove include of headers ``base_interface.hpp`` and ``hardware_interface_status_values.hpp``
-
-4. Add include of header ``rclcpp_lifecycle/state.hpp`` although this may not be strictly necessary
-
-5. replace first three lines in ``on_init`` to
-
-  .. code-block:: c++
-
-    if (hardware_interface::[Actuator|Sensor|System]Interface::on_init(info) != CallbackReturn::SUCCESS)
-    {
-      return CallbackReturn::ERROR;
-    }
-
-
-6. Change last return of ``on_init`` to ``return CallbackReturn::SUCCESS;``
-
-7. Remove all lines with ``status_ = ...`` or ``status::...``
-
-8. Rename ``start()`` to ``on_activate(const rclcpp_lifecycle::State & previous_state)`` and
-   ``stop()`` to ``on_deactivate(const rclcpp_lifecycle::State & previous_state)``
-
-9. Change return type of ``on_activate`` and ``on_deactivate`` to ``CallbackReturn``
-
-10. Change last return of ``on_activate`` and ``on_deactivate`` to ``return CallbackReturn::SUCCESS;``
-
-11. If you have any ``return_type::ERROR`` in ``on_init``, ``on_activate``, or ``in_deactivate`` change to ``CallbackReturn::ERROR``
-
-12. If you get link errors with undefined refernences to symbols in ``rclcpp_lifecycle::node_interfaces::LifecycleNodeInterface``, then add
-    ``rclcpp_lifecyle`` package dependency to ``CMakeLists.txt`` and ``package.xml``
