* New upstream release (http://www.openssh.com/txt/release-5.6):

  - Added a ControlPersist option to ssh_config(5) that automatically
    starts a background ssh(1) multiplex master when connecting.  This
    connection can stay alive indefinitely, or can be set to automatically
    close after a user-specified duration of inactivity (closes: #335697,
    #350898, #454787, #500573, #550262).
  - Support AuthorizedKeysFile, AuthorizedPrincipalsFile,
    HostbasedUsesNameFromPacketOnly, and PermitTunnel in sshd_config(5)
    Match blocks (closes: #549858).
  - sftp(1): fix ls in working directories that contain globbing
    characters in their pathnames (LP: #530714).
