Is it easy to create a game now with 1.6 and then later on change the networking part to 2x? And then I mean mostly the client side. Or are there to many big differences.
Client side there will be small differences.
Is the private beta also for people that use smartfox but do not yet have a license?
The private beta is intended for developers/companies that already own one or more commercial license of SmartFoxServer.
This is not because we want to exclude anyone in particular, but the private beta requires that developers are already familiar with SmartFox so they can immediately jump into coding and testing without step by step docs, and long overviews.
