2.42 Beta was already with AGESA 22.214.171.124, and based on the naming of ASRock BIOS tradition, this should be the retail version (dated as Dec-11-2019) succeeding 2.30 on their website, thanks for sharing in advance.
Thank you for posting. I finally got around to doing a Test of my new Board & CPU PRE-Build. I went ahead and updated the bios and I can confirm Posting with the new bios. I will confirm everything is working as expected when I swap this mobo and cpu into my build later.
