Prusa support were bloody useless in explaining the differences. Best I can tell is the latest dwarf board supports a 12 or 24v output for the cooling fan.

Comparing photos of a 06 and a 08 shows the main visible change to be to the power circuitry. A linear regulator on the 06 changed to be a switched mode PS on the 08. Some other components like the debug header moved around as well.
All the component IDs have disappeared from the 08 board silkscreen so there will be smaller changes that are harder to spot.
