Subject: * Split the ssh binary package into openssh-client and openssh-server
   (closes: #39741). openssh-server depends on openssh-client for some  
 common functionality; it didn't seem worth creating yet another package   for
 this. * New transitional ssh package, depending on openssh-client and  
 openssh-server. May be removed once nothing depends on it. * When upgrading
 from ssh to openssh-{client,server}, it's very difficult   for the maintainer
 scripts to find out what version we're upgrading from   without dodgy dpkg
 hackery. I've therefore taken the opportunity to move   a couple of debconf
 notes into NEWS files, namely ssh/ssh2_keys_merged   and
 ssh/user_environment_tell. * In general, upgrading to this version directly
 from woody without first   upgrading to the version in sarge is not currently
 guaranteed to work   very smoothly due to the aforementioned version
 discovery problems.
