Hades 2 patch brings new stuff even if you've played early access

If you're anything like me, a sicko who has put 200 hours into the early access version of Hades 2, then you might have gone into 1.0 with conservative expectations. There's going to be new stuff, you may have thought, but unless you start over, you've probably already seen the bulk of the game, its relationships, and its combat. Right?
