RELEASE NOTES FOR SLURM VERSION 22.05

IMPORTANT NOTES:
If using the slurmdbd (Slurm DataBase Daemon) you must update this first.

NOTE: If using a backup DBD you must start the primary first to do any
database conversion, the backup will not start until this has happened.

The 22.05 slurmdbd will work with Slurm daemons of version 20.11 and above.
You will not need to update all clusters at the same time, but it is very
important to update slurmdbd first and having it running before updating
any other clusters making use of it.

Slurm can be upgraded from version 20.11 or 21.08 to version 22.05 without loss
of jobs or other state information. Upgrading directly from an earlier version
of Slurm will result in loss of state information.

All SPANK plugins must be recompiled when upgrading from any Slurm version
prior to 22.05.

NOTE: PMIx v1.x is no longer supported.
