+Subject: Various keepalive extensions
+
+Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
+in previous versions of Debian's OpenSSH package but since superseded by
+ServerAliveInterval.  (We're probably stuck with this bit for
+compatibility.)
+
+In batch mode, default ServerAliveInterval to five minutes.
+
+Adjust documentation to match and to give some more advice on use of
+keepalives.
