My first reaction was who cares, aren't all updates in the notifications? But nooo!! I was thinking of the PS4. On PS5 it does notify about updates, but all it says is "Updated", or "Ready to Use", or "Ready to Play".
Having update notes directly from context menu on the game's icon would be nice.
GTSport is awesome for this, it pops a window with all the update notes, images of new stuff, long explanations of new features, red dots in the menus where thre's been new stuff added you didn't look at, it has a list of bug fixes, improvements, car nerfing (*cough*performance rebalanced*cough*) etc... Would be great if they did that at least for all online games that are evolving games that received frequent updates like that.
Bug fixes are nice but I don't really need to know it's not like I'll skip a bug fix. Any feature changes or enhancements should be documented.
