Update recommendations

[aLiEnHeAd]

Hi!
First of all: My system (Z-Way v4.1.4) is running flawlessly at the moment, but I also want to be a litte bit more "future-proof" when z-wave.me comes to an end.
In expert mode it says, I have a new licence available, which probably enables long range and "Fast communications" (btw what's that?).
Can I savely apply this?
My RazBerry7Pro Firmware is version 7.28. Would you recommend to update it?

I came here because I got an error that the GPG signature had expired when trying to update and then found out the project is changing.

I'd too like some alternatives for the future.
