KernelTrap has a post up about the clustering file system that Matthew Dillon is designing.  That's not news to regular readers here, but there was an interesting comment on the story about an existing clustered filesystem called "Lustre".
iXSystems has bought FreeBSDMall.  Interesting, as now it is a company with its own software and hardware product.  There's only a few others like that, who coincidentally also have offered BSD-based products.  (Seen on BSDNews.)
Matthew Dillon's written up a description of how indexing (via B+trees) will be handled in his as-of-yet-unnamed clustering file system.
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.
AsiaBSDCon 2007 has no DragonFly-specific events happening at this point - Masao Uebayashi posted a neighborly welcome for any DragonFly developers to join the NetBSD discussion and beer party on March 9th, starting at 13:00.
OSNews has a news story up about Matthew Dillon's planned new filesystem, with comments of varying utility.
Sascha Wildner has a version of DragonFly 1.8 compiled using NATA, the new ATA system, available on  (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.
"I'm BSD" - linked by Thomas Spanjaard.
It looks like Matthew Dillon is going for his own filesystem to meet DragonFly's clustering goals.  According to his recent post, it will be a (deep breath) 64-bit fsckless logged filesystem with collapsible snapshots limited only by disk space, local caching, and logical-level multi-master replication.  It should have a lasting effect. ETA: summer release, in some form.
Thomas E. Spanjaard has NATA, the 'new ATA' code from FreeBSD, in the DragonFly source tree.  It's in, but not yet enabled, in release 1.8.  If you want to try it out, or if you have certain newer hardware that demands it, he's written how a document on how to enable NATA, on the wiki.
Seen several places: an article about using NULLFS, the BSD filesystem that enables the mounting of a filesystem over itself.  If that sounds confusing, perhaps you should read the article.  Conveniently, NULLFS in DragonFly was recently re-enabled.
