I might not have updated if it had been my choice, but my Vision app auto-updated and it left me with some funkiness (lag) in my camera FPV. I had to do something, so rather than going back to a previous app version, I just went ahead and updated the camera firmware. Now I'm using the new app with the new firmware. Everything's working just fine. Can't say I see any improvement based on only two 15 minute flights, but certainly no performance or reliability problems.
Dont forget to rename the update file when you put it on the microSD. It wont install if you don't. Also, dont forget to delete the .bak file when the update is complete.
