OpenSSH 6.1 has just been released. It will be available from the
mirrors listed at http://www.openssh.com/ shortly.

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0
implementation and includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:

Changes since OpenSSH 6.0
=========================

This is primarily a bugfix release.

Features:

 * sshd(8): This release turns on pre-auth sandboxing sshd by default for
   new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
 * ssh-keygen(1): Add options to specify starting line number and number of
   lines to process when screening moduli candidates, allowing processing
   of different parts of a candidate moduli file in parallel
 * sshd(8): The Match directive now supports matching on the local (listen)
   address and port upon which the incoming connection was received via
   LocalAddress and LocalPort clauses.
 * sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
   and {Allow,Deny}{Users,Groups}
 * Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
 * ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
 * sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
   an argument to refuse all port-forwarding requests.
 * sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
 * ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
 * sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
   to append some arbitrary text to the server SSH protocol banner.

Bugfixes:

 * ssh(1)/sshd(8): Don't spin in accept() in situations of file
   descriptor exhaustion. Instead back off for a while.
 * ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
   they were removed from the specification. bz#2023,
 * sshd(8): Handle long comments in config files better. bz#2025
 * ssh(1): Delay setting tty_flag so RequestTTY options are correctly
   picked up. bz#1995
 * sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
   on platforms that use login_cap.

Portable OpenSSH:

 * sshd(8): Allow sshd pre-auth sandboxing to fall-back to the rlimit
   sandbox from the Linux SECCOMP filter sandbox when the latter is
   not available in the kernel.
 * ssh(1): Fix NULL dereference when built with LDNS and using DNSSEC to
   retrieve a CNAME SSHFP record.
 * Fix cross-compilation problems related to pkg-config. bz#1996
