I've kind of lost track, has it been that long since 3.10.50-1?

Hmm.

I have to admit that after bug 442 seemed fixed, I put cerowrt down
and focused on A) catching up on sleep, B) fixing some sorely busted
infrastructure, and C) getting in some paid work (to make up for the
extra year spent on cero) and D) find ways to get more solid funding
overall, specifically for making wifi fast and E) catching up on
sleep.

I have now built cero not once for over 45 days, and have actually
been to a few social events, and other "normal" things. I have, in
fact, taken off several weekends in a row, for the first time in 3
years. Last week featured my first stage appearance in years at the
sffringe festival, in fact.

I'd dearly like SQM to make BB, but that requires some focused effort
that I don't have in me yet.

Yes, my plan is to rebase on BB once frozen, and do stable updates. At
the moment, however, only trivial bugs in cero remain in the 3.10.50-1
build and I, at least,  can live with them a while longer.

Whether or not we continue onwards to track homenet, adopt new
hardware, or do anything else with this project is up to y'all, and to
funding.

I'd really like to hand off the build engineering process to someone
else, and be able to work more closely with the wifi stack instead, in
particular.

Where would you like it to go?
