ansible/changelogs/fragments/standardize_connection_vars.yaml

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.
