Comment 2 Robert-André Mauchin 🐧 2021-05-17 20:17:53 UTC

I'm in the process of updating AOM to version 3.1.1, when it is released.

I am also considering waiting for libjxl to be packaged and for its dependency highway to have its remaining bugs fixed (hopefully within the next two weeks).
libjxl provides the tune=butteraugli function.
