Very useful information. http://wiki.freebsd.org/ZFS would be a good
place for it.

What I had in mind was the latest MFC regarding ZFS (pool) version 13
on May 20th (two weeks after the 7.2 release):

http://svn.freebsd.org/viewvc/base?view=revision&revision=192498

And the corresponding entry in /usr/src/UPDATING:

"20090520:
        Update ZFS to version 13. ZFS users will need to re-build
        and install both kernel and world simultaneously in order 
        for the ZFS tools to work. Existing pools will continue to work
        without upgrade. If a pool is upgraded it will no longer be
        usable by older kernel revs. ZFS send / recv between 
        pool version 6 and pool version 13 is not supported."

Regargs,
Panagiotis
