Hi Rudolf, I have been investigating the status with the AMD release management, but I have not been given approval to publish any other microcode. I have been trying to track down why there might be a version in the wild that I have not been given for public publishing. It might have come from a BIOS update and not a OS microcode load but I don't have the definitive details on that either. I will publish whatever is released to me as soon as possible.
