Epic has posted the version notes for the next Unreal Tournament update, tentatively scheduled for January 18th. The most prominent changes will be an update to Unreal Engine 4.15 (which will undoubtedly break all of the community maps again) and Flag Run being added to Quick Match.
The most notable item missing is KazeoHin’s Bio Rifle. From forum posts, it looked like it would be a shoe-in for the next build but alas, we will have to wait a bit longer.
The full version notes can be found HERE.
