Can you also please copypaste  min driver notes into our  release notes so
it will be easier for me to track it in case my older gt710 still stuck at
older driver version (not a blocker, I surely can swap headers back to 2020

Thanks and sorry for relative inactivity. I hope to pick up some steam
..... may he after formal New Year date?

Have (good) holidays!
