Lots of QOL repairs, apparently. I haven’t checked it out yet because the patch is pretty damn big, too (almost 29 gigs). Although… is that big, these days? A game that size would have been starkly incomprehensible to me, twenty years ago, let alone a patch.
PS: The Cyberpunk 2077 patch is so late because some hackers decided to try and do some ransomware. …And there’s been nothing on that story since. It’s interesting, really.
