* New upstream release (LP: #535029).

  - After a transition period of about 10 years, this release disables SSH
    protocol 1 by default.  Clients and servers that need to use the
    legacy protocol must explicitly enable it in ssh_config / sshd_config
    or on the command-line.
  - Remove the libsectok/OpenSC-based smartcard code and add support for
    PKCS#11 tokens.  This support is enabled by default in the Debian
    packaging, since it now doesn't involve additional library
    dependencies (closes: #231472, LP: #16918).
  - Add support for certificate authentication of users and hosts using a
    new, minimal OpenSSH certificate format (closes: #482806).
  - Added a 'netcat mode' to ssh(1): "ssh -W host:port ...".
  - Add the ability to revoke keys in sshd(8) and ssh(1).  (For the Debian
    package, this overlaps with the key blacklisting facility added in
    openssh 1:4.7p1-9, but with different file formats and slightly
    different scopes; for the moment, I've roughly merged the two.)
  - Various multiplexing improvements, including support for requesting
    port-forwardings via the multiplex protocol (closes: #360151).
  - Allow setting an explicit umask on the sftp-server(8) commandline to
    override whatever default the user has (closes: #496843).
  - Many sftp client improvements, including tab-completion, more options,
    and recursive transfer support for get/put (LP: #33378).  The old
    mget/mput commands never worked properly and have been removed
    (closes: #270399, #428082).
  - Do not prompt for a passphrase if we fail to open a keyfile, and log
    the reason why the open failed to debug (closes: #431538).
  - Prevent sftp from crashing when given a "-" without a command.  Also,
    allow whitespace to follow a "-" (closes: #531561).
