OpenSSH version 6.7 changelog


 * sshd(8): Support for tcpwrappers/libwrap has been removed.

They've also removed protocol 1 support altogether by now, several old
key exchanges (DH1), keytypes (eg. DSS), etc. It's getting hard to
maintain old boxes over SSH sometimes. 

Since linux boxes pretty much need to be firewalled off from the world
to protect themselves from self-destruction now-a-days, I think people
figure that a firewall is in use for all systems.
