What changes have occurred in the item trading system and trading after the latest update?

The marketplace system appeared in Rainbow Six Siege relatively recently. With the release of the Y9S2, this system came out of beta and received an official release. Any player who has reached level 25 and enabled two-factor authentication can trade items.
