Announce: OpenSSH 5.1 released

OpenSSH 5.1 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.

We have also recently completed another Internet SSH usage scan, the 
results of which may be found at http://www.openssh.com/usage.html

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:
