* check_stanza does not require stanza_class parameter. Introspection! * check_message, check_iq, and check_presence removed -- use check instead. * stream_send_stanza, stream_send_message, stream_send_iq, and stream_send_presence removed -- use send instead. * Use recv instead of recv_message, recv_presence, etc. * check_jid instead of check_JID * stream_start may accept multi=True to return a new SleekTest instance for testing multiple streams at once.
