Don't think its just me having tried this on a second Pi...
I just upgraded a couple of my PoE powered Pi 3b+'s already fitted with PoE hats to 9.2.3. Everything seems to work as expected with the following exception...
The Pi appears to ignore the
entry in config.txt. the fans are still firing off at 50° not the 65° specified.
My previous LibreELEC release (9.2.1) worked exactly as expected with the fan cutting in at 65°
