All the information was released in Asobo’s Dev Blog yesterday.
It’s a USA World Update, not North America (straight from Asobo - it’s community referring to it as North America Update. Asobo have never claimed to be doing anything but USA).
And there’s no way to force the updates yourself. Once they release the core patch that you’ll get either from Steam or the MS Store, THAT will be the new version of the game required for all those other updates to download.
