+  - "proxmox inventory plugin - the current default ``true`` of the ``want_proxmox_nodes_ansible_host`` option has been deprecated.
+     The default will change to ``false`` in community.general 6.0.0. To keep the current behavior, explicitly set
+     ``want_proxmox_nodes_ansible_host`` to ``true`` in your inventory configuration. We suggest to already switch to the new
+     behavior by explicitly setting it to ``false``, and by using ``compose:`` to set ``ansible_host`` to the correct value.
+     See the examples in the plugin documentation for details (https://github.com/ansible-collections/community.general/pull/4466)."

           - Whether to set C(ansbile_host) for proxmox nodes.
           - When set to C(true) (default), will use the first available interface. This can be different from what you expect.
-        default: true
+          - This currently defaults to C(true), but the default is deprecated since community.general 4.8.0.
+            The default will change to C(false) in community.general 6.0.0. To avoid a deprecation warning, please
+            set this parameter explicitly.
