The Xbox One October firmware update is now available for download, with improvements that has been made to the snap feature, and now with your achievements you can add captions when sharing with your friends. The new friends section on the home page menu has also seen an update. Friends are now not hidden away and now there is a monthly global leaderboard to show off your achievement points for that month.
But the biggest and most important update is the DLNA support. There is now also a MKV playback via the USB or DLNA. To put it short, its the update everyone has been looking for.
