How big are the changes in v3? I have been away for awhile and my app was coded when 2.1.3 was the latest and now i want to add the Facebook SDK but i fear that it will not work with 2.1.3? Can anybody confirm or deny? Essentially i want to know if i can track mobile app installs from Facebook ads with the new Facebook SDK on cocos2d-x 2.1.3 and if not how much of a difference from 2.1.3 to 3 is?
Updating cocos2dx from v2.1.3 to v3
