If your machine is running fine and great, there should be no need to update the BIOS. It should only be updated if you experience issues, or you have a specific issue that is fixed in the new BIOS.  
I see that there's (finally) a new BIOS upgrade after 2.2.1 and 2.2.2 that broke my machine and necessitated a new motherboard and blocking automatic upgrades.2.2.4 (14th Dec 2021) What happened to 2.2.3? So. What does this version fix? And more importantly; is it safe?I have no intention of installing this one, till I hear the all clear. My machine is fine and running great, so...
Aurora R10, BIOS 2.2.4
