[ssh.1 ssh_config.5 sshd.8]
     Remove mentions of weird "addr/port" alternate address format for IPv6
     addresses combinations. It hasn't worked for ages and we have supported
     the more commen "[addr]:port" format for a long time. ok jmc@ markus@

[auth-options.c auth-options.h auth.c auth.h auth2-pubkey.c]
     [key.c servconf.c servconf.h sshd.8 sshd_config.5]
     add some optional indirection to matching of principal names listed
     in certificates. Currently, a certificate must include the a user's name
     to be accepted for authentication. This change adds the ability to
     specify a list of certificate principal names that are acceptable.

     When authenticating using a CA trusted through ~/.ssh/authorized_keys,
     this adds a new principals="name1[,name2,...]" key option.

     For CAs listed through sshd_config's TrustedCAKeys option, a new config
     option "AuthorizedPrincipalsFile" specifies a per-user file containing
     the list of acceptable names.

     If either option is absent, the current behaviour of requiring the
     username to appear in principals continues to apply.

     These options are useful for role accounts, disjoint account namespaces
     and "user@realm"-style naming policies in certificates.

     [sshconnect2.c sshd.8 sshd.c sshd_config.5]
     Add support for certificate key types for users and hosts.

     OpenSSH certificate key types are not X.509 certificates, but a much
     simpler format that encodes a public key, identity information and
     some validity constraints and signs it with a CA key. CA keys are
     regular SSH keys. This certificate style avoids the attack surface
     of X.509 certificates and is very easy to deploy.

     Certified host keys allow automatic acceptance of new host keys
     when a CA certificate is marked as sh/known_hosts.
     see VERIFYING HOST KEYS in ssh(1) for details.

     Certified user keys allow authentication of users when the signing
     CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS
     FILE FORMAT" in sshd(8) for details.

     Certificates are minted using ssh-keygen(1), documentation is in
     the "CERTIFICATES" section of that manpage.

     Documentation on the format of certificates is in the file
     PROTOCOL.certkeys

     Add support for tun(4) forwarding over OpenSSH, based on an idea and
     initial channel code bits by markus@. This is a simple and easy way to
     use OpenSSH for ad hoc virtual private network connections, e.g.
     administrative tunnels or secure wireless access. It's based on a new
     ssh channel and works similar to the existing TCP forwarding support,
     except that it depends on the tun(4) network interface on both ends of
     the connection for layer 2 or layer 3 tunneling. This diff also adds
     support for LocalCommand in the ssh(1) client.
