    """Method called to retrieve the latest uploads to a given backend,
    via, for example, RSS or an API.
    Not all backends may support this.  It can be used to look for updates
    much more quickly than scanning all known projects.

        :obj:`list`: A list of 4-tuples, containing the project name, homepage, the
        backend, and the version.

            when the versions cannot be retrieved correctly

            support batch updates.
