I am in Darlington. We get to South Shields fairly frequently with the Grandson, who loves the fairground.
When they upgrade FF6, which is going to happen in the next 24hrs, to version 6.5, our good friend "DS2ATC" will work his magic on it as soon as he can, but he is busy this week as stated above.
Generally I continue to run on the old version for a good few days to see if anyone on the forum comes up with issues. Its not going to cause you any drama not upgrading it.
Firmware upgrades for the Anafi and Flight Controller, wont affect what has been done in FF6, unless Parrot have decided to close that backdoor, but to be honest they dont seem to be as touchy as DJI, so we may be ok.
