Personally, I dont see any major changes after the update. Im sure there are some bugs fixed or mE flaws but overall, very much the same game since launch. The major downsides of the game are still there. Still same strange designer choices like the player database is absolutley useless because you cant use the arrow keys and things like that.
The game isn't 100% fixed, still issues which are bugging people, but for me, the game is now playable, the UI is still horrible and needs work, but overall in my opinion the game is worth buying.
