I somehow recently managed to learn and develop a game using 2.2.2 , but with lot of changes going into Cocos2d-JS 3.0, should I consider using it right now and update my games in progress or should I continue to use the Cocos2d-HTML5 2.2.2
Is there any chance that you will stop supporting the 2.2.2 version?
You can compare the difference in upgrade guide, it covers pretty much every aspects that have been changed in 3.0, I ensure you that Cocos2d-JS 3.0 is very promising, especially if you want to use JSB to deploy your application to native.
