Yesterday, November 13th 2017, Valve pushed a new CS:GO update. This update will have some major changes in matchmaking by adding Trust Factor instead of prime by default, although players who wish, can still use the old prime system. Also, this patch will end Operation Hydra and make Matchmaking 2v2 (Wingman) and Flying Scoutsman permanent game modes.

The patch also delivered a new designed set of badges to matchmaking ranks.
