That would be commit 367f6b950f62adef04c8c877f5e29889e6e22c64, which 
only included minor changes to the e-Up module, so that can be ruled out 
as the causing commit.

Did you check your network wifi SQ & reconnect settings?

Not that they would make any difference from that commit, but maybe it's 
not the commit but some random Wifi fluctuation causing an occasional 
switch to cellular.

That should be clearly visible in the logs though.
