OpenBSD 4.6 Released
pgilman writes "The release of OpenBSD 4.6 was announced today. Highlights of the new release include a new privilege-separated smtpd; numerous improvements to packet filtering, software RAID, routing daemons, and the TCP stack; a new installer; and lots more. Grab a CD set or download from a mirror, and please support the project (which also brings you OpenSSH and lots of other great free software) if you can."
OpenBSD's FAQ explains their choices regarding ISO images.
I like to install OpenBSD from a floppy image - only 1.44 MB! I then choose an FTP mirror and install whatever parts I want on the fly.
