The developers have begun a restructuring of the code.
It base to make parts of Open SSH as a library to access.
The Open-BSD developers write here about this new released:
OpenSSH 6.7 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.
