I thought we'd squashed this "old client" rumor already?

"And yes, I have seen the same rumors that it’s old, but it’s not entirely true. We tried to include the best we had on a stable approach, but in our eagerness to please we wanted to get a few additional fixes out (hence we pushed the launch back a couple of hours). In order to reach the May 1st date some of those fixes led to unwanted side-effects which weren’t discovered in time."
