What are the features differences and/or fixes for a Mavic Air between 4.34 and 4.39?

Just to be clear, firmware is the software that runs on the Mavic Air itself.  It sounds like you are actually talking about the DJI Go 4 app.  For version history details, you can go to the iTunes page for the app and click on the "Version History" link on that page.

Aint no Mavic Air FW with those reference numbers??

What you're asking is in regards to the Go4 app and not firmware.

Yes, I am referring to the DJI Go app.
I am running 4.33 and I see that the latest one is 4.39 (for IOS).
What are the difference between them?

Thanks.
I just checked the link and see that for the most part the differences are not related to the Air.
There is also a bunch of generic stuff.
I was hoping to see new features or stuff like that.

As for as I can tell it’s no real difference.
