[slurm-announce] Slurm version 17.11.8 available

[Tim Wickberg]

We are pleased to announce the availability of Slurm version 17.11.8.

This includes over 30 fixes made since 17.11.7 was released at the end 
of May. This includes a change to the slurmd.service file used with 
systemd, this fix prevents systemd from destroying the cgroup 
hierarchies slurmd/slurmstepd have created whenever 'systemctl 
daemon-reload' is called (e.g., by yum/rpm).

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