-DragonFly is an operating system and environment originally based on -FreeBSD. DragonFly branched from FreeBSD in 2003 in order to develop -a radically different approach to concurrency, SMP, and most other -kernel subsystems. -
- -DragonFly belongs to the same class of operating system as BSD and Linux and is based on the same UNIX ideals and APIs. DragonFly gives the BSD base an opportunity to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series.
-From 2003 to early 2007 the DragonFly project focused on rewriting most -of the major kernel subsystems in order to support the second phase of -the project. This involved a great deal of work in nearly every subsystem, -particularly the filsystem APIs and kernel core.

We have also adopted the PkgSrc system for management of all non-base-system third-party applications in order to pool our resources with other BSD projects using the system.
+In the 2007-2008 time-frame a new filesystem called HAMMER was developed +for DragonFly. HAMMER sees its first light of day in the July 2008 +2.0 release.
