Ahh, so in the changelog:
- UPDATED: Merged GPL 384_8137 and binary blobs 384_7968
for RT-AX88U.
The GPL is the code you compile and the binary blobs are just that.. binaries you get?
So the fixes they mention in the changlog are in the GPL and not the binaries.
Some portions of the code are closed source (like the wireless drivers). These are what I call "binary blobs", as I receive them in pre-compiled form as part of a GPL release. These are model specific, which means if a newer GPL is released for a different (like in this case, 8137 was released for the RT-AX58U), then I can only reuse the open source parts of that release, and must keep the binary components from the last release for the model which I support (in this case for the RT-AX88U, it means 7968).
