Stretch was released, could this move forward now? I think this [0] patch may help fix/diagnose a bug I observed in the current version of the package in sid.

That beta is actually older than the newest release (1.7.3.2). I wonder if this is a bug in the tracker that contributed to the new release being overlooked for so long. 1: https://tracker.debian.org/pkg/socat
