Some major user-visible changes include:
+Samba now includes support for version 2.1 of the SMB protocol,
+the SMB2 version of Windows 7 and 2008R2, including dynamic
+reauthentication and support for multi-credit (large MTU).
+Consequently, Samba negotiates SMB 2.1 by default: The value "SMB2"
+for the configuration parameter "max protocol" has been changed to
+be an alias for SMB 2.1. Previously, the default SMB2 version of
+Samba was the original version 2.0 of SMB that was shipped with
+Windows Vista and 2008.
