Game Saves: Prior to this update game saves for 2048, Super 2048, and Cookie Clicker was only supported locally in flat-file format. This has been changed and saves are now stored in your database if you have it enabled. The data is fetched when a player joins and cached internally and then uploaded again when they disconnect. The remaining cached data, if any, is uploaded on server shutdown. This is all done asynchronously so you won't notice any performance impacts at all.
A new table is created on reload/restart named "saves". This table stores all saves from every game and every user.
Change: Cookie Clicker now autosaves every 30 seconds instead of 60 seconds.
