"This update has a hefty load on its shoulders, with Meeble Burrows--the brand-new subterranean battle content--as well as battle- and system-related adjustments tucked tightly into its knapsack. Prepare for your own trek by reading up on some of the included content below!"
Version update is apparently going to be sometime before the end of the month. Meeble Burrows is the obvious highlight and it looks like the only other "main" inclusions are the changes to the Super Kupowers and the PC Collision adjustment, unless they pull some surprises. New 2-hours (or should I say SP abilities) certainly won't make the cut.
