So sad, almost want to cry...
So 2.5 came and went, 2.6 is here but no solo geth|parity mining.../frowny face & upset tummy.
I think I am the only person asking for it, so not surprised. But will I be surprised with 2.7b?!?
The good news is that there are other requests for solo mining

No promises but there might be an experimental support for it in 2.7.
I will take experimental any day of the week!
