minor_changes: | Connection plugins have been standardized to allow use of ``ansible_<conn-type>_user`` and ``ansible_<conn-type>_password`` variables. Variables such as ``ansible_<conn-type>_pass`` and ``ansible_<conn-type>_username`` are treated with lower priority than the standardized names and may be deprecated in the future. In general, the ``ansible_user`` and ``ansible_password`` vars should be used unless there is a reason to use the connection-specific variables.
