FreeBSD 7.1-RELEASE Released!
Tuesday, January 6th, 2009The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 7.1-RELEASE. This is the second release from the 7-STABLE branch which improves on the functionality of FreeBSD 7.0 and introduces some new features. Some of the highlights:

- Boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices.
- The cpuset(2) system call and cpuset(1) command have been added, providing an API for thread to CPU binding and CPU resource grouping and assignment.
- KDE updated to 3.5.10, GNOME updated to 2.22.3.
- DVD-sized media for the amd64 and i386 architectures
