What changes have occurred in the Rainbow Six Siege meta after the latest update?

In attack, the most meta operators are hard breachers Buck and Thermite, capable of dealing a lot of damage and less dependent on teammates, as well as Thatcher, whose EMP grenade is one of the best gadgets in the game. On defense, operators specializing in information gathering such as Valkyrie and Mira, as well as the device neutralizer Jäger, stand out.
