..versionadded:: 2.5
In Ansible 2.5, a new jinja2 function called ``query`` was added for invoking lookup plugins. The difference between ``lookup`` and ``query`` is largely that ``query`` will always return a list.
The default behavior of ``lookup`` is to return a string of comma separated values. ``lookup`` can be explicitly configured to return a list using ``wantlist=True``.
This was done primarily to provide an easier and more consistent interface for interacting with the new ``loop`` keyword, while maintaining backwards compatibiltiy with other uses of ``lookup``.
