My kids’ school uses a web portal to add money to their lunch accounts. My only task when I open this website is to pick an amount and click submit and give them my money.

Whose idea was it to show me a “what’s new” popup of all the jira tickets they closed in the last sprint?

What’s new? Nothing is new. It works just like it used to. Just take my money and leave me alone, please.

But if you have (through whatever process) sent them a complaint that, say, "it doesn't work right using Firefox X.Y running on Windows 7", then those release notes might in fact be interesting to you. So there actually is a reason for you to be able to see them. Not for them to get in your way, though. 99% of the people won't care.
