We have not done a release in a while. Not because we stopped,
rather the opposite (customer deliverables).

We don't talk about it much here because we're keeping intentional
distance between the projects, but it's no secret most of the engineers
behind j-core work for https://se-instruments.com. (We're making sensor
systems to allow renewable energy to displace fossil fuels in utility
grids. At our last big conference the banner said "fault resolution to 3
meters". Except in Japanese, because it was "Smart Energy Week" at
"Tokyo Big Site".)

For context why this is such an exciting area to be in right now, here's
a Stanford professor named Tony Seba (no relation to us, never met him,
he's just a business-side domain expert in this space) teaching a class
in 2013, then giving a book talk last year, then having his book talk
analyzed by a mutual fund in india earlier this year:

The j-core project is a separate fully open source entity, but there's
some serious resource contention going on right now staffing-wise. Sorry
about that.

Make of that what you will, but I tend to believe Rob. He has a good
track record on deliverables. (You might know Toybox, Rob & friends'
answer to BusyBox, https://en.wikipedia.org/wiki/Toybox . Rob and Bruce
Perens used to work together on BusyBox, but had some sort of falling
out. https://lwn.net/Articles/202120/ No offence whatsoever intended
to either of these good gentlemen.)
