We are pleased to announce the official release of OpenBSD 5.2. This is our 32nd release on CD-ROM. 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, 5.2 provides significant improvements, including new features, in nearly all areas of the system. The most significant change in this release is the replacement of the user-level uthreads by kernel-level rthreads, allowing multithreaded programs to utilize multiple CPUs/cores. Some highlights: GNOME 3.4.2, KDE 3.5.10, Xfce 4.10, MySQL 5.1.63, PostgreSQL 9.1.4, Postfix 2.9.3, Mozilla Firefox 3.5.19, 3.6.28 and 13.0.1, Mozilla Thunderbird 13.0.1, LibreOffice 3.5.5...
