Upgrade steps for this release
As always, prior to upgrading, create a backup of your USB flash device: "Main/Flash/Flash Device Settings" - click "Flash Backup".
Update all of your plugins. This is critical for the NVIDIA and Realtek plugins in part
Upgraded from 6.12.3 to 6.12.4 and it went mostly smoothly as everything is running fine and well now.
However, I followed the instructions and did shutdown the array before upgrading. Upon reboot, unRAID briefly came online (web GUI and all) and then completely crashed. This has happened upgrading to 6.12.0, 6.12.1, 6.12.2, 6.12.4; but NOT 6.12.3. My IPMI records show this for each of the upgrades. This is the ONLY time my machine has EVER crashed; only after the FIRST reboot af
