v1.45.1

Changed

• The update page is one page now. Opening it shows your version and a
  turning ring while it checks - the check has always started on arrival, but
  nothing on screen said so. If something newer exists, the offer appears under
  your version instead of replacing it: the download icon, the version you are
  on and the one on offer, and Install at the bottom of the screen.
• The card is labelled "Version" rather than "Installed version".
