BSD based DragonFly Release 2.2.1 is out

DragonFly 2.2 is out :

The DragonFly 2.2 release is out! The HAMMER filesystem is considered production-ready in this release. It was first released in July 2008. The 2.2 release represents major stability improvements across the board, new drivers, much better pkgsrc support and integration, and a brand new release infrastructure with multiple target options.

Three release options are now available: bare-bones CD ISO, a DVD ISO which includes a fully operational X environment, and a bare-bones bootable USB disk-key image which is less than 512M.
