The update banner can no longer get stuck behind the scenes

When we ship an improvement, your open windows download it quietly in the background and show a small “Update ready — tap to refresh” banner. That banner had a blind spot: occasionally the new version finished downloading and then sat waiting for a go-ahead signal that never arrived. No signal, no banner — and no banner meant no tap, which was the very thing that would have un-stuck it.

The app no longer waits to be told. It now checks directly whether a finished update is sitting there ready — both right when a window opens and the moment a download completes — and offers the banner immediately. Tapping it puts you on the latest version, same as always. And the old rule still holds: the app never reloads itself; that only ever happens when you tap.
