DST changes, maybe

If you are running a DragonFly system older than version 1.6, and you are in North America using something other than UTC time, you will need to manually update your tzinfo files to reflect the changed (in 2005, taking effect this year) Daylight Savings Time start and stop dates.  If you are on UTC or are running 1.6+, you are fine.

1.8 ISO with NATA

Sascha Wildner has a version of DragonFly 1.8 compiled using NATA, the new ATA system, available on leaf.dragonflybsd.org.  (Link goes directly to a bzipped ISO)  Try it if you’ve had trouble getting DragonFly to install on a system with a very new SATA controller.
