+ Ssh crashed if a message was sent on a channel with
+ packet_size = 0.</p>
+ <p>
+ A new option for ssh:daemon is also introduced:
+ <c>minimal_remote_max_packet_size</c>. This option sets
+ the least max packet size declaration that the daemon
+ will accept from a client. The default value is 0 to
+ maintain compatibility with OpenSSH and the rfc:s.</p>

+ Fixes the bug that once the <c>rekey_limit</c> bytes (by
+ default, 1GB) had been transmitted the connection was
+ rekeyed every minute, not after the next transferred
+ 'rekey_limit' chunk.</p>

+ The options <c>system_dir</c> and <c>user_dir</c> assumes
+ that the value is a path to a directory which is
+ readable. This is now checked early, so <c>ssh:daemon</c>
+ and <c>ssh:connect</c> will fail with an error message

+ Better usage of binary matching in ssh_auth.erl and

+ <p>
+ A new option 'preferred_algorithms' is available for
+ <c>ssh:daemon</c> and <c>ssh:connect</c>.</p>
+ <p>
+ This option defines the algorithms presented to the peer
+ in the algorithm negotiation phase of the ssh protocol. </p>
+ <p>
+ The default list can be obtained from the new function
+ <c>ssh:default_algorithms/0</c>.</p>

+ *** INCOMPATIBILITY with removed undocumented options
+ 'role' and 'compression' ***</p>

+ The internal group to user_drv protocol has been changed
+ to be synchronous in order to guarantee that output sent
+ to a process implementing the user_drv protocol is
+ printed before replying. This protocol is used by the
+ standard_output device and the ssh application when
+ acting as a client. </p>
+ <p>
+ This change changes the previous unlimited buffer when
+ printing to standard_io and other devices that end up in
+ user_drv to 1KB.</p>

+ If ssh_connection:subsystem/4 fails we do not want to
+ crash but rather terminate gracefully.</p>

+ <p>
+ New option <c>id_string</c> for <c>ssh:daemon</c> and
+ <c>ssh:connect</c> for limiting banner grabbing attempts.</p>
+ <p>
+ The possible values are: <c>{id_string,string()}</c> and
+ <c>{id_string,random}</c>. The latter will make ssh
+ generate a random nonsence id-string for each new
+ connection.</p>

+ To enable the ssh daemon to run in a virtualized
+ environment, where there can be more that one server that
+ has the same ip-address and port, we add a new option
+ profile.</p>

+ A new option for handling the SSH_MSG_DEBUG message's
+ printouts. A fun could be given in the options that will
+ be called whenever the SSH_MSG_DEBUG message arrives.
+ This enables the user to format the printout or just
+ discard it.</p>

+ Testcase improvements and corrections:</p>
+ <p>
+ * Add testcases for the <c>disconnectfun</c> option on
+ both server and client sides</p>
+ <p>
+ * Timeout testcases adjusted for slow machines where they
+ sometimes failed</p>

+ Own Id: OTP-12789</p>
+ </item>
+ <item>
+ <p>
+ A new option unknown_msgfun/2 for ssh:connect and
+ ssh:daemon for handling unknown messages. With the option
+ it is possible to intercept before an INFO log message is
+ generated.</p>
+ <p>
+ One usage is to filter out messages that are not wanted
+ in the error logger as info reports. An example of such a
+ message is the 'etimedout' tcp error message that will be
+ received if a connection has keep_alive and the peer is
+ restarted.</p>
