FreeBSD 8.0 is the next expected release of FreeBSD, having been branched from the trunk in August 2009. It will feature superpages, Xen DomU support, network stack virtualization, stack-smashing protection, TTY layer rewrite, much improved ZFS support, a new USB stack, multicast updates including IGMPv3, and rewritten NFS client/server introducing NFSv4. Inclusion of improved device mmap() extensions will allow the technical implementation of a 64-bit Nvidia display driver for the x86-64 platform. FreeBSD 8.0 release date has slipped to early November 2009.[38]
