This update has a round of item balancing to try to bring some stats in line with being more balanced. A few meta upgrades were tuned as well. I know nobody likes things being nerfed but some values were a bit extreme.
I also have Steamworks integration in this build as the precursor to the new Achievement update hopefully coming this week, barring any huge issues. Lots of folks have been asking for them and I've had them in game, they just didn't link up with Steam yet so you'll start to see achievements coming through to Steam after the Achievement update this week.
