I am running Armbian on four HardKernel HC2's and everything is working perfectly. The four SBC's are running a Moosefs cluster running Ubuntu 18.04 and Armbian 5.85, and this leads to my questions:
I am trying to decide whether to upgrade as apt is proposing moving to 5.89 The change log does not currently list 5.89 and shows 5.87 as the newest. Am I missing something?
When I look at previous change logs it is difficult to decipher which fixes impact the HC2/HC1/XU4. Is there an easy way to tell?
How do you decide when to upgrade?
Is it even worth upgrading when running more mature boards like this one? My boards run inside a private network behind a firewall, and my #1 priority is stability and reliability.
