Well, Mark, you can check the full changelog that Isaac and I finalized
here; our primary focus at the current moment are longstanding bugs listed in the bugs forum, and several of the "this feature is coming in X version" posts that're lingering about still. As you can see from the full changelog, a lot of data was handled and modified from 7.5.8.
I updated my initial post in this thread to reflect the finalized changelog that we issued for 7.5.9 once we sent it off.
