The new release touches pretty much every subsystem and overhauls quite a lot of them, so most bugs that were present would not be present anymore (and new bugs will be present, whee!). Anything to do with AI logic isn't really touched yet, though Badger and I have been working on some things based on your comments here, Magnus -- so thanks for that.
I expect many many bugs in the new version when that first comes out, and I'm going to be intentionally breaking savegames for another two weeks or so, several times a week, as yet more major changes in the Era of Discovery come out. My intent is that by about September 7th we're stable again in terms of not majorly redoing tons of ships to the point that older savegames wouldn't make sense, etc.
When the new version comes out tomorrow, it won't have all the proper stats and abilities on every ship, and it won't have procedural ship code in there yet. As we process those various things, it will change the game to the point that each release needs to be started fresh for a bit, anyway.
