Dif between G1.5 and 4.0

[Bull.]

I send my 4 fly to Impact Paintball to upgrade the soft, it returns with the 4.0. One and a half week later, when I consulted the performance angel site to see the specs of my new soft a new version is available now.
I´ve 2 questions:
1) Can anybody tell the de difference between g1.5 and 4.0?
2) MT´s don´t know when a new version of something / whatever is going to be available in few days?

ok we know weeks in advance unless something changes over night. that is what has happened to you. g1.5 is g7 software 4.0 is fly

I bought an 4 fly rasta and before use it I send it to Jim to upgrade the soft and it came back with the LP 4.0. The other backman of my team, ICEFA of Moonwalkers from Argentina, send his 4 fly board (only) to Bob to do the same thing and it returns back with the g1.5 v.

I check out the site of fix my angel and there figure that the g1.5 is for 4 fly boards too. So my dude is: Jim upgraded my board with an old soft version or not? If not, why at fix my angel figure that the g1.5 is for flys too?
