Well, I've been playing 1.7 for a bit now. Besides the other bugs already mentioned, I keep hoping for fixes for the following:
1. Something about the simultaneous turns makes the AI ranged units end up occupying the same square during tactical combat. This game is too good to not fix this.
2. Path to Exile Quest: The Hailstone Staff reward is not good enough any more with the new Mage-centric weapons. It is 12 Attack with -6 Init. This reward should be some Champion only item like the Mage's Staff, but preferably something a bit better.
I'll keep updating as I find more.
