I am getting the following error
“The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.”
when I try to upgrade with the file openwrt-ar300m-4.3.7-0913-1694589403.tar for v4.3.7 downloaded here GL.iNet download center

As stated in the other thread. You may need to go to 3.216 before going to the latest 4.3.7.

Ok, I was able to incrementally upgrade, the UI and different version naming confused me, thanks!
