+Version 1.61
+------------
+Fix append problem to Samba servers (files opened with O_APPEND could
+have duplicated data). Fix oops in cifs_lookup. Workaround problem
+mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
+Disable use of server inode numbers when server only
+partially supports them (e.g. for one server querying inode numbers on
+FindFirst fails but QPathInfo queries works).
+
 Version 1.60
 -------------
 Fix memory leak in reconnect.  Fix oops in DFS mount error path.
