Oh, and I notice that capitulation now occurs prior to combat. I thought that was a good idea. Now I realize the problem:
Attackers can take even home planets without contest if they're a little bit lucky.
Hmmmm, I didn't change that. Fleets do their moves first (including trade, colonization, planetary assault), then Planetary Defense, then fleet-fleet battle.
Changing the order around causes all sorts of unintended consequences, as you might imagine... I'm open to discussion about it, if there's a better order I'm glad to hear it.
Hehe, and I've been talking about making these changes for a week!
