It appears a new update for the Xbox One controller has appeared for those who are in Microsoft's Xbox Preview Program, using the New Xbox Experience (NXE).

　　Players aren't exactly sure on what the update includes, but according players on both Reddit and Neogaf, the update fixes some connection issues that members using the NXE were having.

　　NXE were unable to 'quick connect' their controller to the Xbox One after a new update rolled out. This firmware update (2.3.2381.0) seems to fix that issue. After the update, NXE users were again able to connect their controller to the Xbox One within mere seconds.
