Subtitles 1.17.1

• No update offered for a version you already have. If you installed a
  newer Subtitles yourself after the app had found an update, the menu could
  keep offering that older version. It now forgets an update that isn't
  newer than the copy running, and clears it when a check finds nothing new.
• The welcome window's demo lists the new languages. Its Language /
  Models and Translate To menus show Polish and Swedish, and Danish and
  Norwegian under Experimental, as the app's own menus do.
