* New upstream release (http://www.openssh.org/txt/release-5.9).

  - Introduce sandboxing of the pre-auth privsep child using an optional
    sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables
    mandatory restrictions on the syscalls the privsep child can perform.
  - Add new SHA256-based HMAC transport integrity modes from
    http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt.
  - The pre-authentication sshd(8) privilege separation slave process now
    logs via a socket shared with the master process, avoiding the need to
    maintain /dev/log inside the chroot (closes: #75043, #429243,
    #599240).
  - ssh(1) now warns when a server refuses X11 forwarding (closes:
    #504757).
  - sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths,
    separated by whitespace (closes: #76312).  The authorized_keys2
    fallback is deprecated but documented (closes: #560156).
  - ssh(1) and sshd(8): set IPv6 traffic class from IPQoS, as well as IPv4
    ToS/DSCP (closes: #498297).
  - ssh-add(1) now accepts keys piped from standard input.  E.g. "ssh-add
    - < /path/to/key" (closes: #229124).
  - Clean up lost-passphrase text in ssh-keygen(1) (closes: #444691).
  - Say "required" rather than "recommended" in unprotected-private-key
    warning (LP: #663455).
