Magic v2 MagicOS8 downloaded

I've just had a popup saying MagicOS8 has been downloaded and would I like to install (I'm in uk).

On the one hand I'm very excited and on the other I nervous. Looks like an oldish version, too 8.0.0.105 where I've seen from other people's screenshots that they have 8.0.0.144 or even 8.0.0.157?

Do you know if we can rollback to old version of we have too many issues with upgrade?

Has anyone installed 8.0.0.105 and would you recommend installing it or avoiding it?
