The posting of the Destiny 2 update 2.2.0 patch notes signals that the new season is upon us, meaning that players can finally get an up-close look at all that's changing now that the man they call the Drifter has stepped into the spotlight.   

There's a lot going on here, much of it the usual tuning and tweaks—shotgun rate of fire values have been adjusted based on frame type, for instance, while a Curse of Osiris shader called Metallic Sunrise has been renamed to Mercurian Sunrise, because I guess somebody forgot and made a Metallic Sunrise shader for Forsaken—but there some big changes to the way the game's most notorious weapons work.
