    by user dirkmueller + RBrownFactory
    - update to 1.1.8:
      * Moved the MemcacheArgs.dead_retry argument and the
        MemcacheArgs.socket_timeout argument which were erroneously added to the
        “set_parameters”, where they have no effect, to be part of the Memcached
        connection arguments MemcachedBackend.dead_retry,
        MemcachedBackend.socket_timeout.
      * Added MemcacheArgs.dead_retry and MemcacheArgs.socket_timeout to the
        dictionary of additional keyword arguments that will be passed directly to
        GenericMemcachedBackend().
      * Added RedisBackend.connection_kwargs parameter, which is a dictionary of
        additional keyword arguments that will be passed directly to StrictRedis() or
        StrictRedis.from_url(), in the same way that this parameter works with the
        RedisSentinelBackend already
