I understand about the release notes popup. Unfortunately as an extension author, it's one of the only ways I have to actually communicate to users. Most don't follow the Page on Facebook. So when I make significant changes, I may pop up an update page. But this definitely doesn't happen for minor releases. I hope you and others understand. I spend MANY hours of my life on this for free, and IMO it's not too much of an intrusion to be able to keep people informed every so often.
