Dürer Lounge in NUE must have been refreshed since the report in 2018 of bubufr
in this post.
The lounge is now upstairs, next to the boarding gates, although there is no view on the apron. I was on traveling on AF1211 departing at 15h40 and the lounge was staffed at that time. The dragons did have a paper list of all passengers of the flight eligible to lounge access.
Not a lot of passagers in there while I was in the lounge, so lot of room available with different type of spaces (armchairs, table, desk...). Food option was quite descent with a good variety of drinks, nice bretzels with other sandwiches and desserts, and of course some sausages/mustard/bread with a recipe to cook your own "Drei im Weckla".
