Where in the Store can we find the update notes? (Store mini-rant)

I know they’re at http://www.ultra-combo.com/patch-notes-3-04/ but I’m referring to in the Windows Store specifically. I mean, usually I have to go to the app’s Store page (by the way, accessing the Killer Instinct page last night crashed the Store…way to go MS!) and hope that the update notes are there, but why can’t we just see the update notes (for ALL apps, not just KI) right there in the same place we click “Update”, like the App Store on iOS?

And how about listing the actual size, too. Don’t assume it’s 0.1MB total and gradually increase it on me. Hell I was afraid I’d have to redownload the game again since I wasn’t sure how updates work on the Windows Store.
