Oh, I forgot to document one other change:

Fighter Carriers (ship types) now require their own tech area, as well as Ship Construction. This was done because it makes sense, offers interesting decision (research carriers, or make do with other ways to deploy fighters), and also because it solves the bug where analyzing a light carrier would give an empire (which lacked fighter tech) level 2 knowledge of fighter technology.
