From overclock.net:
"I'd also recommend that for i7 SMP users, you
don't switch to this client just yet. We're not yet certain how -bigadv will work on this client at the moment, but will post something when we find out. TC Folders, as you've been told, don't switch to this client until you get a message from me. I highly doubt you'll be able to assign separate passkeys within the client, so we need to see how things go. "
