The new version brings ULE as the default scheduler, DTrace inside the kernel framework, booting from USB devices, improved NFS Lock Manager (NLM) client, a new cpuset(2) system call and cpuset(1) command that brings an API for thread to CPU binding and last but not least DVD-sized media (only i386 and amd64). Until now there were only CD ISO images available.
