+Node name and namespace parameters changed
+""""""""""""""""""""""""""""""""""""""""""
+
+The ``Node`` action parameters related to naming have been changed:
+
+- ``node_name`` has been renamed to ``name``
+- ``node_namespace`` has been renamed to ``namespace``
+- ``node_executable`` has been renamed to ``executable``
+- ``exec_name`` has been added for naming the process associated with the node.
+  Previously, users would have used the ``name`` keyword argument.
+
+The old parameters have been deprecated.
+
+These changes were made to make the launch frontend more idiomatic.
+For example, instead of
+
+.. code-block:: xml
+
+   <node pkg="demo_nodes_cpp" exec="talker" node-name="foo" />
+
+we can now write
+
+.. code-block:: xml
+
+   <node pkg="demo_nodes_cpp" exec="talker" name="foo" />
+
+This change also applies to ``ComposableNodeContainer``, ``ComposableNode``, and ``LifecycleNode``.
+For examples, see the `relevant changes to the demos. <https://github.com/ros2/demos/pull/431>`_
