[Tim Wickberg]

We are pleased to announce the availability of Slurm version 17.11.6.

This includes over 50 fixes made since 17.11.5 was released eight weeks 
ago, including a race condition within the slurmstepd that can lead to 
hung extern steps.

Slurm can be downloaded from https://www.schedmd.com/downloads.php
