minor_changes:
- "docker_container, docker_network, docker_volume - return facts as regular variables ``container``,
   ``network`` respectively ``volume`` additionally to facts. This is now the preferred way to
   obtain results. The facts will be removed in Ansible 2.12."
- "docker_service - return results as regular variable ``services``; this is a dictionary mapping
   service names to container dictionaries. The old ansible facts are still returned, but it is
   recommended to use ``register`` and ``services`` in the future. The facts will be removed in
   Ansible 2.12."
