Stable release: TypeScript coding; Construct Game Services; Better multi-monitor support & lots more.
Glad we're finally getting a universal leaderboard sometime soon, that would be greatly appreciated. My only other recommendation would be cloud save. I think the 2 major issues behind that are the cost of server space plus the development time behind implementing it. I would definitely not mind paying extra to use server space, or just a way to simply implement our own server with a tutorial example. It sucks when players buy consumable iap's and they lose that when they either get a new phone or something happens to their current phone and have to wipe everything.
