edeliver_fork v1.4.5 Edeliver.Relup.Instructions.ResumeRanchAcceptors

This upgrade instruction resumes the ranch acceptors

which were suspended by the

Edeliver.Relup.Instructions.SuspendRanchAcceptors

instruction at the beginning of the upgrade. Because real suspending of ranch acceptors is not possible because ranch acceptors do not handle sys messages, they were actually terminated and are restarted by this relup instruction.
