I dunno about the next version, right now I am very caught up (Well I am always caught up but this time its more serious). I'll post it as soon as possible.
I haven't made a complete list of improvements because there was at least 400 changes which would make me go mad to track and write them down. Sorry...Maybe soon.
Yes it improves the AI.
1) It changes the AI development tactics of all nations.
2) New mod version makes AI cast spells more intelligibly.
Feel free to ask anymore doubts or questions . I am at your side .
