# DragonFly Release 2.6
-## XX March 2010 (2.6.0)
-
+## 5 April 2010 (2.6.1)
The DragonFly 2.6 release is here!
-Three release options are now available: Our bare-bones CD ISO, a DVD ISO which includes a fully operational X environment, and a bare-bones bootable USB disk-key image (1G disk keys recommended).
+Three 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.
-In addition we will for the first time be shipping a 64-bit ISO. 64-bit support is stable but there will only be limited
-pkgsrc support in this release. Both the bare-bones CD ISO and a bootable USB disk-key image are available for the 64-bit release.
+Two 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.

### pkgsrc packages
doing a UFS install and not the default HAMMER install. We also recommend installing from the CD ISO
and not the DVD ISO. The DVD ISO HAMMER install has bugs (see [[Known Release Issues|issues24]]).
-**DVD ISO HAMMER install bugs (2.6.0 only)** - You will get a 'guard1x fail @...' loader panic.
-See [[Known Release Issues|issues24]] on how to fix.
