-	- call on_next_submit callback even fro aio_group - impact unknown,
+3.1  Thu Oct  2 13:34:40 CEST 2008
+	- pre-deref the passed callback object, for increased speed
+          and decreased memory usage.
+	- call on_next_submit callback even for aio_group - impact unknown,
           but seems more correct.
+        - $req->cb now returns the original callback.
         - (libeio) pass EIO_GROUP/aio_group requests through the queue without
           requiring a thread switch.
+        - (libeio) status code of aio_futime and aio_utime was always passed 0.
         - do some other µ-optimisations.
