Python 3,7?

Is there any plans to upgrade python3 package to 3.7?

On OpenWrt there is a 3.7 version but not accessible from GL-S1300.

If not is it possible to install it in some way?

I don’t know if there are any plans to upgrade the package at the moment, but if you need it now, you can compile it using the GL SDK from here:

You can also check out this thread to understand the build process for packages in OpenWRT a bit better:

You can apply that to any package.
