The update went fine . I'll have to do more investigating , and/or translate the Japanese or wait for the English translation , to learn about all the changes . The ones I've noticed so far and really like are as follows :

1- Ability to extend the 90s range check by hitting a RESET button before the 90s is up .
2- I can finally sort my model names !
3- Functions can be named to be more meaningful ( now which aux is my nose gear door....? )
4- Changing modulation and RX type less cumbersome than in the past.

So far so good . I recommend it to any 14MZ owners !
