In order to optimize it, I've had to recode some parts, so if you are a bit far in the game (namely if you have used a lot of technics beyond the 100 marks and/or if you've completed a lot of guild quests in general above 3 pts), you might want to keep a copy of your old version just to stay on the safe side - some perks might also no longer work.
However, if you're not too far in the game, or have yet to play it, make sure to use the newest versions!
