DragonFly BSD 2.0 was released yesterday by the development team. DragonFly BSD is a fork of FreeBSD 4.8 and offers an alternative to the FreeBSD 5.0 series.

DragonFly BSD was created in 2003 by FreeBSD developer Matthew Dillon who differed with the FreeBSD team over the threading and symmetric multiprocessing approach taken with FreeBSD 5.0.

DragonFly BSD is available as a Live CD so users can test out the OS before installing to hard disk.

Among the changes included in this release are the first Hammer filesystem which features crash recovery on mount (without fsck) and queueless incremental mirroring.

A number of kernel changes have also been included as well as new drivers, better USB survivability and newer versions of contributed software such as BIND, OpenSSH, tnftpd, and GCC.
