There is:

20090520
	Update ZFS to version 13. ZFS users will need to re-build
                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	kernel and world. 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.

It was committed as part of the ZFS MFC in r192498.

Regards,
