small updates are done in firmware, regarding minor bugs, and some features like delay to restart the unit, cancel-able delays, etc. which firmware you have exactly? when the controller powers up it shows it for a while.

In the software there is not any update at all.



I have not been playing with these for the last 5 years, except a board redesign about 3 years ago, in a time I had a lot of free time to spent.
