Can anyone explain why Parrot released the 1.6.4 and 1.6.5 firmware? What did you want to fix? I understand that adding new features requires new firmware. Version 1.6.3 has made many new features available, but not much has changed since then.
DJI drones have the ability to (slightly hidden) downgrade their firmware, but it is still a great courage to try out a new firmware ... Many have fallen down, many have become remote bricks (Spark), or simply crashed once (disabling OTG, range reduction / live video reduction).
Parrot cannot undo the firmware update so you have to think hard.
And after many people in this forum complain about new updates, many will update immediately ...
1.6.3 works fine for me and I don't see why I should upgrade. After all, it was the latest and it worked.
If someone reads: Do not update if you are satisfied with the operation! Only if Parrot comes up with something you need, but wait until it turns out there is no mistake ...
