Comment 8 for bug 1944475

I tested the version of ubuntu-release-upgrader in the -proposed pocket for Hirsute and was able to start a distribution upgrade without interaction. Additionally, I ran 'sudo do-release-upgrade -d --frontend=DistUpgradeViewText' and '--frontend=DistUpgradeViewGtk3' and saw the release notes with the version from -proposed. I'm subsequently setting the bug to verification-done.
