We have over 21,000 people on here. If you look at how many people report in Alpha/Beta/RC. Very little. Therefore, "most people" update to the latest (beta) is misleading.
Example: I found a minor bug in an important feature in UNA 9.0.0-RC2 which forced UNA to update to RC3 in less than 24 hours. https://una.io/page/view-discussion?id=461 and several RCs as far as to RC11 before final release. We still got bugs in 10.0.0-RCs as well. So, bugs in RCs is nothing new.
Already saw this issue before this post. Alex T mentioned a bug and yet you ask "why release?" is as whining as tantrum. A bug that you are having issue with is Studio App Market: Issues with modules updates. Pretty sure, the team did not see that coming until just after released. Refresh don't always work. If that's the case, I gave a clue on clearing browser's cache.
I do not have Auto-Update and on self-host... a few hiccups here and there. Overall, all modules updated. Sorry that some of yous failed and sharing sorrows while some of us succeeded and gloating.
On the bright side, thrilled to see some new features and bugs addressed. Keep on examining to squash 'em buggers!
