Subtitles 1.17.0

• Polish and Swedish. Both are in Language / Models, and in Translate
  To. They use the same 633 MB download as Multilingual, so if you already
  use Multilingual there is nothing more to download. Swedish can't be
  translated to or from Russian, Ukrainian, Polish, Arabic or Hindi, which
  Apple's translation doesn't offer for it; every other pair works.
• Danish and Norwegian, as experimental. They are under a new
  Experimental heading in Language / Models. Expect more mistakes than in
  the other languages, and choose them there rather than leaving them to
  Multilingual, which can mistake them for German, English or Swedish.
  Like Swedish, they can't be translated to or from Russian, Ukrainian,
  Polish, Arabic or Hindi.
• Subtitles in four more languages. The app's menus, windows and
  messages are now in Polish, Swedish, Danish and Norwegian too, chosen
  under Settings ▸ Language or following your Mac.
• Translate To shows what can't be translated. A language that can't
  be translated from the language being spoken is greyed out: the one you
  chose, or with Multilingual the one last heard. If the speaker changes to
  a language that can't be translated into your choice, the captions stay
  in the original language while they speak.
