Just in time for the new servers I'm about to set up, FreeBSD 7.1 is out. Release notes here. Significant changes in this release include availability of DVD-sized install media on the download mirrors, and making the ULE scheduler the default in the i386 and AMD64 kernels (ULE was available before as an option, but the default was the older 4.4BSD scheduler). The new scheduler improves performance significantly for many workloads on multi-processor systems.
