Can anyone provide a list of the last few firmware versions and their changes? I have an EVO with version 1.11. I think I would like to upgrade it to get the enhanced exercise options but didn't know what else changed and what is the latest version number (1.20?). My dealer charges so I want to make sure I want it first.

Are you doing your own maintenance or are they? If they're charging for firmware upgrades while they are already there for maintenance, I'd find a new dealer...

That being said, the last version that really does any good would be 1.17 (so far). After that they were updates for the 2800 Aux Shutdown Alarm wiring and switches.

You would want to be above 1.11 though. There were several improvements like a slip ring frost warmup, cold weather start timers and such that were between 1.11 and 1.17.
