* Added Linux 3.7 compatibility
* Added SMB integration 'zfs set sharesmb=on ...'
* Added "-o ashift" to 'zpool add' and 'zpool attach'
* Added vev_id support for device link aliases
* Allow zpools to be created on top of zvols
* Allow GPT+EFI vdevs for root pools
* Fixed renaming zvols with snapshots
* Fixed deadlock observed under a heavy rsync workloads
* Fixed ELOOP error on auto-mounted snapshots
* Fixed SELinux security xattr support
* Fixed incorrect mtime/ctime update for mmaped I/O
* Fixed get/set users/groups in quota props via numeric id
* Improved AF hard disk detection
* Improved performance when unlinking files with xattrs

Might be better asked on the zol mailing list? I'm waiting for the ubuntu repo to update then I'm upgrading my rc12 system. Not using zfs root tho...

You've been able to "hack" this for a while, but it now looks as if it's become a supported option with the ZoL package.

There's some instructions here

Here's a "hack" for Fedora

Have to add though that I haven't bothered doing this myself, at least not yet anyway! (just don't have the pressing need TBH - will probably get round to it at some point though )

ZFS on Linux (ZOL) has been able to do root pools for awhile. The difference now is that it can also do it on GPT+EFI systems. Personally its a feature I haven't used as I run my system disk as ext3 and only use ZFS for storage purposes (also makes it easier to recover if a kernel update breaks ZFS as well).
