I am curious why the most recent driver release for the x470 chipset (18.50.0422) only has a single file difference between it and the release from November (18.10.181012). That file difference is the CIMManifest.xml which has Version="18.10-181012a-334539E-AMD" in the older and Version="18.50-181012a-334539E-AMD" in the newer. Every other single file is exactly the same.
(fwiw, looks like there are lots of differences for the RAID chipset drivers from the last set)
