Well,

As Evan pointed out the release notes for my v6.02 says it's good til Mar 2017. Latest v6.06 say nothing about compatibility of earlier versions. The FLARM web site is ambiguous about this.

It will literally take me 20 minutes to haul the fuselage out and upgrade. I don't have a problem with that.

FLARM really needs to get their act together and make it LOUD AND CLEAR stating what is and is not compatible.
