FreeBSD 7.1-RELEASE Announcement

The 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:

• The ULE scheduler is now the default in GENERIC kernels for amd64 and i386 architectures. The ULE scheduler significantly improves performance on multicore systems for many workloads.

• Support for using DTrace inside the kernel has been imported from OpenSolaris. DTrace is a comprehensive dynamic tracing framework.

• A new and much-improved NFS Lock Manager (NLM) client.

• 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
