Hi,
From what I have seen, there is a new OsmAnd~ version available and F-Droid has it flagged as manual update.
Let’s hope that the build problems mentioned by the maintainer are no longer existing, to make life easier and that he will have some time available in the upcoming days/weeks to check it out.
Anyway, thanks a lot for keeping F-Droid up and running 
Have a great day!
