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 availability of an updated release of DragonFly BSD, version 1.12.2: "DragonFly BSD 1.12.2 released. A significant number of bug and security fixes have been merged from current to the 1.12 branch over the last two months and we have rolled a new sub-release, 1.12.2, for the benefit of our users. We recommend that 1.12 users upgrade. In addition there is a known issue related to building pkgsrc packages from source which is addressed in the above release notes. Basically the M4 package sources needs to be patched. This applies to HEAD users as well." Changes: "Fix wide symbols (wstring, wint_t etc) support in gcc41 (libstdc++); add libc support for gcc41 stack protector; update bzip2 to 1.0.5...." See the release announcement and release notes for further details and errata issues. Download (MD5): dfly-1.12.2_REL.iso.gz (124MB).
