+ AI will play harder in campaign at lower levels (AI was designed to be somewhat nerfed on the early missions of the campaign to give players a gentle introduction.
+ Various improvements to the Terran Alliance and Arcean AIs.
+ Made some tweaks to show ships are designed such that even if they prefer to build ships with a particular weapon system, they will also bear in mind what types of weapons they have already researched (i.e. they may WANT to put beam weapons but if they only have Laser I but have Black Hole Generators for mass drivers it'll still build Black Hole Generators on their ships rather than just tossing a bunch of lasers on a ship simply because they prefer beam weapons at that point. It did this before but now it has a better algorithm)
