What has happened to the miner? I wondered why on new drivers the DEAD error was coming up and looks like the miner has not really been updated this year.

You must give more info about your system, drivers, cards, what algo you mine.
I mine eth on RX580 8Gb latest drivers and Windows 10. All works fine.
My bad bro.
I have Win 10 Pro (1903), vega 56, Adrenalin 20.4.1, usually mine on Saber (TUBE). After going over the settings few times it looks like the miner, only asking as its not had an update on Git for over 4 months which may be just waiting till the devs are back.
