The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX.
Theo de Raadt has announced the release of OpenBSD 4.4, a BSD operating system with a strict security philosophy and advanced security features: "We are pleased to announce the official release of OpenBSD 4.4. This is our 24th release on CD-ROM (and 25th via FTP). We remain proud of OpenBSD's record of more than ten years with only two remote holes in the default install. As in our previous releases, 4.4 provides significant improvements, including new features, in nearly all areas of the system: new or extended platforms for sparc64, socppc, landisk; improved hardware support; new tools and functionality; assorted improvements and code cleanup; install and upgrade process changes; OpenSSH 5.1; over 4,500 ports, minor robustness improvements in package tools (Firefox 3, GNOME 2.20.3, Inkscape 0.46, KDE 3.5.8, OpenOffice.org 2.4.1, Xfce 4.4.2...."
