Applied about 30 minutes ago, and so far so good. They changed the interface and stats page a little (nothing major, just how the GH/s is presented).

Hash rate is at 1.4TH/s (power step '7'), which is more or less what it was at before...I'll give it a couple hours and check back to see if it stabilized any higher. If it looks good, I'll probably try stepping up the power a bit to see if I can get one or more of the cores to go offline like before (power step '8' and above triggered it for me).
