FreeBSD 4.x Forked Into DragonFly
DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. Prominent former FreeBSD developer Matthew Dillon is a major player in the development. According to the website, DragonFly gives "the BSD base an opportunity to grow in entirely new direction from the one taken in the FreeBSD-5 series."
