[slurm-users] Slurm versions 20.02.1 and 19.05.6 are now available

[Tim Wickberg]

We are pleased to announce the availability of Slurm versions 20.02.1 
and 19.05.6.

This includes a series of minor fixes since the last maintenance 
releases for both branches.

Please note that the 19.05.6 release is expected to be the the last 
maintenance release of that branch (barring any critical security 
issues) as our support team has shifted their attention to the 20.02 
release. Also note that support for the 18.08 release ended in 
Februrary; SchedMD customers are encourage to upgrade to a supported 
major release (20.02 or 19.05) at their earliest convenience.

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