DragonFly 1.6 is released, (see announcement) with highlights including:

• even better pkgsrc integration, with over 93% of pkgsrc‘s 6,000+ packages building on DragonFly
• significant 802.11 improvements including ath(4) support
• clustering progress
• and many other changes.
• See the diary or the release page for exhaustive update detail.

ISO images and/or source updates are available from a number of mirrors, though I suggest the torrent.
