Welcome to the Forum, @aviator736cy! 
That’s now the production version:
Note:
It may be possible to get that same version from the beta channel by enabling that in the app ( Account ➜ About ➜ Beta Program ➜ select device types you want to enable for beta firmware download), but I don’t know if that would get you there any more quickly or not. Please be aware that you also want to be current with the production app (at least v3.9+).
