8776a914 1# DragonFly Release 2.6
8a77bc5d 2## 5 April 2010 (2.6.1)
8776a914 3
4The DragonFly 2.6 release is here!
5
8a77bc5d 6Three release options are now available for 32-bit: Our bare-bones CD ISO, 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 has in the previous release to work around issues with DVDs simply being too slow to boot an X environment from.
8776a914 7
8a77bc5d 8Two release options are available for 64-bit: Our base-bones CD ISO and our bare-bones bootable USB disk-key image. The 64-bit release is now fully supported.

23### pkgsrc packages
24
25We offer over 8000 pre-built [pkgsrc](http://www.pkgsrc.org) packages for this release. The [pkg_radd(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_radd&section=ANY) utility may be used to download pre-built binary packages. By default this script will query the main package site for a random redirect to one of our mirrors. The path can be overridden by setting BINPKG_SITES in `/etc/settings.conf`.
26
27To get a list of all packages, let [pkg_search(1)](http://leaf.dragonflybsd.org/cgi/web-man?command=pkg_search&section=ANY) download the summary file for that release:
28
29 # pkg_search -d
30
31We supply a Makefile in /usr to track the pkgsrc tree. We also supply a GIT mirror of the NetBSD pkgsrc CVS repo as
32well as the pkgsrc/wip (work in progress) repo at git://git.dragonflybsd.org/pkgsrc.git and we recommend that
33users use it instead of pulling from NetBSD with CVS. Our GIT mirror is updated four times a day.

35## DragonFly 2.6.x Special Installation and Upgrade Notes
36
37**VirtualBox and VMWare users** - Unless your virtual hard disk is 50G or larger we recommend
38doing a UFS install and not the default HAMMER install. We also recommend installing from the CD ISO
39and not the DVD ISO. The DVD ISO HAMMER install has bugs (see [[Known Release Issues|issues24]]).
