The 1.12 release is out now, and should be available on any of the mirrors. I’m blockquoting the announcement:

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.
