We are pleased to announce the official release of OpenBSD 4.0.
This is our 20th release on CD-ROM (and 21st via FTP). We remain
proud of OpenBSD's record of ten years with only a single remote
hole in the default install. As in our previous releases, 4.0
provides significant improvements, including new features, in nearly
all areas of the system.
