All is well. cpuminer-opt development is winding down, running out of ideas. I have one more release coming with some new optimizations
and propagating existing optimizations to another algo or 2 that doesn't yet have ASICs. After that I don't know.

If you want to talk, send me an email or PM.

----------

Before the next release I'd still like some data for zen4 in case the builds need to be tweaked.
