Not all users necessarily update to the most recent firmware. I am aware that the most firmware, for example, breaks certain commands. As an example, EDITMAT doesn't work properly and is somewhat crucial in displaying the results in a solver app I wrote. So I have kept one of my Primes on an older firmware for this reason.
