v7.4.3

• Check for updates from anywhere. A button in the top bar (desktop and tablet) shows your
  version and checks GitHub when you press it: it says when you are up to date, or the update bar
  appears. With an update waiting it lights up and opens Settings → Updates. On a phone the
  version at the foot of More is the same button, and "Check for updates" is in the command
  palette (Cmd/Ctrl+K). The web UI updates with its engine, so it has no button.
