As far as I know, the most recent firmware is 01.01.05.40.
I haven't tested for anything yet. I lived in Thailand and was wondering if DJI would still change or refund the camera if there was a problem. We don't have an official store here, so I purchased it from a dealer, and I'm not sure how is their policy is.

I think dealers have different policies in different countries. You should prolly ask the dealer.

Maybe you have a new features

Does it have HDR and RockSteady+ ?

there are two firmwares just telling all half the story wins all over

I don't have a ruler that comb is 6inchs long, then I place twice of its lenght
30cm = roughly 12inchs

yes, the video looks fine to my eye but I don't know if it should perform better because I don't have anything else to compare

thank you. let's see hows it work in real world

The outdoor video looks really nice even in 720p on my MacBook Pro screen. And at 1080p even them telephone wires are so sharp they burned a hole on my retina.
