The thorough revision of culture didn't happen. All I managed was to get links to particular nations updated, without going into many more specifics. I also didn't do much with anthropology or personal studies except complete their sets of links to earlier history, and I didn't touch science at all. I also did a few technical changes, revising the file structure, and published the whole update to the web.
So, I'll be starting the cycle back over, mostly with history, although I may look at other areas just for the sake of variety.
