As I said before, I just deliver the firmware files to the community and
the firmware team creates the actual releases. But my understanding is
that these are from different branches which are built independently
(and might have different features, like in this case the mesh support)
so I would not make any conclusions if any firmware is "better" just
from the numbers alone.
