Wonder if you can elaborate on what one gains by moving
from protocol 7 to either 8 or 9. thanks!

FLARM provides extremely good backwards compatibility;
a display device can request an older protocol and it just works.
Butterfly code had a few minor issues that cropped up over the years,
like parsing assumptions that used to be OK but became invalid over time.
Butterfly now requests version 7 which all operational devices support.
Details of changes in 8 and 9 are in the protocol documentation chapter 6;
not important for most users (especially in USA) nor for Butterfly.

Hope that helps!
