Release notes:

(http://www.openssh.com/txt/release-6.2)

ssh(1)/sshd( 8 ) : Added support for AES-GCM authenticated encryption in
SSH protocol 2. The new cipher is available as aes128-gcm@openssh.com
and aes256-gcm@openssh.com. It uses an identical packet format to the
AES-GCM mode specified in RFC 5647, but uses simpler and different
selection rules during key exchange.

* ssh(1)/sshd(8 ) : Added support for encrypt-then-mac (EtM) MAC modes
for SSH protocol 2. These modes alter the packet format and compute
the MAC over the packet length and encrypted packet rather than over
the plaintext data. These modes are considered more secure and are
used by default when available.

* ssh(1)/sshd(8 ) : Added support for the UMAC-128 MAC as
"umac-128@openssh.com" and "umac-128-etm@openssh.com". The latter
being an encrypt-then-mac mode.
