DragonFly是一份作为FreeBSD-4.x系列在逻辑上的延续而设计的操作系统及应用环境。这些操作系统与Linux可归为相同的类别，因为它们都基于UNIX理念及应用程序接口。DragonFly是这条发展道路上的一个分支，可以说，是给了BSD一个向着不同于FreeBSD-5系列的崭新方向而发展的机会。

Matthew Dillon has announced the release of DragonFly BSD 2.2, a BSD operating system originally forked from FreeBSD 4.8: "TheDragonFly 2.2 release is here! The HAMMER filesystem is consideredproduction-ready in this release; it was first released in July 2008.The 2.2 release represents major stability improvements across theboard, new drivers, much better pkgsrc support and integration, and abrand new release infrastructure with multiple target options. Threerelease options are now available - our bare-bones CD ISO, a DVD ISOwhich includes a fully operational X environment, and a bare-bonesbootable USB disk-key image (less than 512M). We offer over 7,300pre-built pkgsrc packages for this release. The pkg_radd(1) utility maybe used to download pre-built binary packages. By default, this scriptwill query the main package site for a random redirect to one of ourmirrors." Read the detailed release notes for further information.
