Link zur englischen Version dieser Seite auf der man die im Text angesprochene .zip auch findet.
I had trouble finding the current firmware because a search engine pointed me to the German site. And that said "unpack the .zip zu the card10" but no link to any .zip was on the page. Because I am sure nobody wants to update the German page every time the firmware is updated I pointed the user to the English page so she hopefully finds the current version even if she doesn't speak English :)
