The wait to see if this version is stable enough to be worth upgrading to. 6.12.1 broke a bunch of docker processes apparently and 6.12.2 fixed those but had its own issues from what I was seeing people post.
May have been people with very esoteric setups. Easy enough to test, nothing is going to break. Just back up usb key before upgrading. If it doesn’t work you just restore the backup, no need for panic.
FWIW both of my 6.12 systems upgraded flawlessly. I run a handful of common dockers on my main system and very few on my backup machine.
I’m toying with upgrading mine to the latest release remotely. I’m on the other side of the world away from my servers right now but not a significant risk imho. Supermicro IPMI makes it pretty risk free.
