+	b10-auth now also experimentally supports statistics counters of
+	the rcode reponses it sends. The counters can be shown as
+	rcode.<code name>, where code name is the lowercase textual
+	representation of the rcode (e.g. "noerror", "formerr", etc.).
+	Same note applies as for opcodes, see changelog entry 364.
