revert perpetrate usually and propulsion
git checkout maestro git revert a8172f36 #hash of the perpetrate you privation to destruct # this introduces a fresh perpetrate (opportunity, it's hash is 86b48ba) which removes adjustments, launched successful the perpetrate successful motion (however these modifications are inactive available successful the past) git propulsion root maestro
