We are pleased to announce the availability of Slurm version 22.05.1.

This includes one significant fix to an regression introduced in 22.05.0 
issue that can lead to over-subscription of licenses. For sites running 
22.05.0 the new "bf_licenses" option to SchedulerParameters will resolve 
this issue, otherwise upgrading to this new maintenance release is 
strongly encouraged.

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