Civ 1.3 patch changes?

Is anyone else noticing a big change in the AI? I didn't really notice it with the Blackbeard 1.3 release, but then they put out the patch to lessen the AI sanctions. It just seems a lot has changed.

One thing I've noticed is Wonder building progression is much different. The AI prioritizes the Gate of All Nations almost every game (sub 50 turn builds on it continually). But it's other ones as well. The other thing I noticed is they are HYPER aggressive now. The last 2 games I've played had 4 different AIs war deck me in both games. These are really early wars.... like pre turn 40-45.

I don't really see anything in the patch notes that would indicate much of a change. Maybe bad luck?
