Just had a big patch that added or fixed a bunch of stuff.
The one I was excited about was the AI patching to make it more competitive. So far, it works to an extent (perhaps it works differently at different levels). It's supposed to make the AI upgrade their military units (or produce more modern units). In my first game with it, the AI seemed to do that for a while, but now that I've gotten on a roll militarily, I'm finding my competitive is still about two eras back (and not particularly well prepared).
Edit- by the way, that whole first post is the way it automatically displays when you link reddit now.
