+Version 1.54
+------------
+Fix premature write failure on congested networks (we would give up
+on EAGAIN from the socket too quickly on large writes).
+Cifs_mkdir and cifs_create now respect the setgid bit on parent dir.
+Fix endian problems in acl (mode from/to cifs acl) on bigendian
+architectures.
 Version 1.53
 ------------
 DFS support added (Microsoft Distributed File System client support needed
