NEW • BSD Release: DragonFly BSD 2.0 |
 |
Matthew Dillon announced the availability of DragonFly BSD 2.0: "2.0 is our eighth major DragonFly release. DragonFly's policy is to only commit bug fixes to release branches." Changes in this release include: the HAMMER filesystem featuring crash recovery on-mount (without fsck) and queueless incremental mirroring, numerous kernel changes like native fairq-queue implementation and native connection state recovery, various hardware changes like added drivers and better USB survivability, userland changes like blacklist for weak Debian-generated SSH keys and improved manual pages and documentation, a lot of contributed software like new versions of BIND, OpenSSH, tnftpd, and GCC. Fortran was removed from the base system, along with other old stuff like legacy device drivers. See the rather brief release announcement and the detailed 2.0 release notes for more information. Download (MD5): dfly-2.0.0_REL.iso.gz (129MB, torrent).

| About DragonFly
|
| DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series.

BSD Release: DragonFly BSD 3.4.1 |
|
Justin Sherrill has announced the release of DragonFly BSD 3.4.1, a UNIX-like operating system created in 2003 as a fork of FreeBSD 4.8: "Version 3.4 of DragonFly BSD is officially out." Big ticket items of the release include: "Experimental packaging system - dports uses the FreeBSD ports system to build ports for DragonFly and uses pkgng to manage the binary packages produced from those ports; The DragonFly snapshots are built using dports and also have Xfce for the desktop; performance improvements under extreme load - improvements in poudriere performance, tmpfs performance and CPU usage; new default compiler - the two base compilers have swapped roles, GCC 4.7, introduced as an alternative compiler with release 3.2, is now the primary compiler used to build DragonFly; new USB stack - USB4BSD." See the brief release announcement and read the detailed release notes for a full list of new features and improvements.

BSD Release: DragonFly BSD 3.2.1 |
|
Justin Sherrill has announced the release of DragonFly BSD 3.2.1, an updated version of the BSD operating system originally forked from FreeBSD 4: "The 3.2.1 release of DragonFly BSD is available now. Significant work has gone into the scheduler to improve performance, using postgres benchmarking as a measure. See the PDF of graphed results to see the improvements. DragonFly should be now one of the best selections for PostgreSQL and other databases. USB4BSD has been incorporated into this release. More USB devices are compatible with DragonFly, and xhci (USB 3.0) users may be able to take full advantage of their newer hardware. Since this is a new feature, it is available in 3.2 but not built by default. See the release announcement and the release notes for further information.

BSD Release: DragonFly BSD 2.6.1 |
|
Matthew Dillon has announced the release of DragonFly BSD 2.6.1, a BSD operating system originally forked from the FreeBSD 4.x code base: "The DragonFly 2.6 release is here! Three release options are now available for 32-bit: our bare-bones CD ISO image, a bare-bones bootable USB disk-key image (minimum 1G USB stick needed), and a GUI bootable USB disk-key image with a full X environment. The GUI USB image replaces the DVD ISO image we had in the previous release, to work around issues with DVDs simply being too slow to boot an X environment from. Two release options are available for 64-bit: our bare-bones CD ISO image and our bare-bones bootable USB disk-key image. The 64-bit release is now fully supported."

BSD Release: DragonFly BSD 2.4 |
|
Matthew Dillon has announced the release of DragonFly BSD 2.4, a general-purpose operating system originally forked from FreeBSD 4.x: "The DragonFly 2.4 release is here! Three release options are now available: a bare-bones CD image, a DVD image which includes a fully operational X environment, and a bare-bones bootable USB disk-key image. In addition we will for the first time be shipping a 64-bit ISO image. 64-bit support is stable but there will only be limited 'pkgsrc' support in this release. DragonFly BSD 2.4 is a bigger release than normal. The single most invasive change is the introduction of DEVFS. The /dev file system is now mounted by the kernel after it mounts the root file system. All major and minor numbers have changed and the old /dev is no longer meaningful."
