For those people testing HAMMER, the HAMMER on-media format has
    changed so you will have to newfs any HAMMER filesystems.

    I know I have said this before, but there's a very good chance that no
    more on-media changes will be made after this point.  The official
    freeze of the on-media format will not occur until the 2.0 release,
    however.

    The testing of the reblocking and pruning code continues.  There
    are still a handful of bugs related to parallel operations while
    reblocking and pruning which I expect to be worked out this week.
