+Version 1.57
+------------
+Improve support for multiple security contexts to the same server. We
+used to use the same "vcnumber" for all connections which could cause
+the server to treat subsequent connections, especially those that
+are authenticated as guest, as reconnections, invalidating the earlier
+user's smb session. This fix allows cifs to mount multiple times to the
+same server with different userids without risking invalidating earlier
+established security contexts. fsync now sends SMB Flush operation
+to better ensure that we wait for server to write all of the data to
+server disk (not just write it over the network). Add new mount
+parameter to allow user to disable sending the (slow) SMB flush on
+fsync if desired (fsync still flushes all cached write data to the server).
+Posix file open support added (turned off after one attempt if server
+fails to support it properly, as with Samba server versions prior to 3.3.2)
+Fix "redzone overwritten" bug in cifs_put_tcon (CIFSTcon may allocate too
+little memory for the "nativeFileSystem" field returned by the server
+during mount).
+
+Version 1.56
+------------
+Add "forcemandatorylock" mount option to allow user to use mandatory
+rather than posix (advisory) byte range locks, even though server would
+support posix byte range locks. Fix query of root inode when prefixpath
+specified and user does not have access to query information about the
+top of the share. Fix problem in 2.6.28 resolving DFS paths to
+Samba servers (worked to Windows). Fix rmdir so that pending search
+(readdir) requests do not get invalid results which include the now
+removed directory. Fix oops in cifs_dfs_ref.c when prefixpath is not reachable
+when using DFS. Add better file create support to servers which support
+the CIFS POSIX protocol extensions (this adds support for new flags
+on create, and improves semantics for write of locked ranges).
+
+Version 1.55
+------------
+Various fixes to make delete of open files behavior more predictable
+(when delete of an open file fails we mark the file as "delete-on-close"
+in a way that more servers accept, but only if we can first rename the
+file to a temporary name). Add experimental support for more safely
+handling fcntl(F_SETLEASE). Convert cifs to using blocking tcp
+sends, and also let tcp autotune the socket send and receive buffers.
+This reduces the number of EAGAIN errors returned by TCP/IP in
+high stress workloads (and the number of retries on socket writes
+when sending large SMBWriteX requests). Fix case in which a portion of
+data can in some cases not get written to the file on the server before the
+file is closed. Fix DFS parsing to properly handle path consumed field,
+and to handle certain codepage conversions better. Fix mount and
+umount race that can cause oops in mount or umount or reconnect.
+
+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. Fix problems with preserving timestamps on copying open
+files (e.g. "cp -a") to Windows servers. For mkdir and create honor setgid bit
+on parent directory when server supports Unix Extensions but not POSIX
+create. Update cifs.upcall version to handle new Kerberos sec flags
+(this requires update of cifs.upcall program from Samba). Fix memory leak
+on dns_upcall (resolving DFS referralls). Fix plain text password
+authentication (requires setting SecurityFlags to 0x30030 to enable
+lanman and plain text though). Fix writes to be at correct offset when
+file is open with O_APPEND and file is on a directio (forcediretio) mount.
+Fix bug in rewinding readdir directory searches. Add nodfs mount option.
