Hi!
Thank you Hans for the very quick fix on the libertinus font!
It works very nicely. I played with the test file you sent me, and I
find that in the .lfg file, the up parameter set to 0.06 instead of
0.1 looks better to me.

PS I do not use them, but I noticed that the quadruple prime f''''
still uses small primes.
