DragonFlyBSD 1.12 has been released. "This release is primarily a maintainance update. A lot of work has been done all over the kernel and userland. There are no new big-ticket items though we have pushed the MP lock further into the kernel. The 2.0 release is scheduled for mid-year. Of the current big-ticket item work, the new HAMMER filesystem is almost to the alpha stage of development and is expected to be production ready by the mid-year 2.0 release."
