[slurm-users] Slurm versions 18.08.6 is now available, as well as 19.05.0pre2, and Slurm on GCP update

[Tim Wickberg]

We are pleased to announce the availability of Slurm version 18.08.6, as 
well as the second 19.05 release preview version 19.05.0pre2.

The 18.08.6 includes over 50 fixes since the last maintenance release 
was made five weeks ago.

The second preview of the 19.05 release - 19.05.0pre1 - is meant to 
highlight additional functionality coming with the new select/cons_tres 
plugin, alongside other recent development work. Please consult the 
RELEASE_NOTES file for a detailed list of changes made to date.

Please note that preview releases are meant for testing and development 
only, and should not be used in production, are not supported, and that 
you cannot migrate to a newer release from these without potential loss 
of data and your job queues.

I'd also like to call attention to some of our recent work in 
partnership with Google. There's a blog post today highlighting some of 
this recent work both on Slurm and with the slurm-gcp integration 
scripts (https://github.com/SchedMD/slurm-gcp):
