>  -- Add SchedulerParameters option of bf_hetjob_prio=[min|avg|max] to alter the
>     job sorting algorithm for scheduling heterogeneous jobs.
>  -- Fix initialization of assoc_mgr_locks and slurmctld_locks lock structures.
>  -- Fix segfault with job arrays using X11 forwarding.
>  -- Revert regression caused by e0ee1c7054 which caused negative values and
>     values starting with a decimal to be invalid for PriorityWeightTRES and
>     TRESBillingWeight.
>  -- Fix possibility to update a job's reservation to none.
>  -- Suppress connection errors to primary slurmdbd when backup dbd is active.
>  -- Suppress connection errors to primary db when backup db kicks in
>  -- Add missing fields for sacct --completion when using jobcomp/filetxt.

>  -- Remove unused -b flag from getopt call in sbatch.
>  -- Disable reporting of node TRES in sreport.
>  -- Re-enabling features combined by OR within parenthesis for non-knl setups.

>  -- Fix nodes not getting reboot RPC when job requires reboot of nodes.
>  -- Fix failing update the partition list of a job.
>  -- Use slurm.conf gres ids instead of gres.conf names to get a gres type name.
>  -- Add mitigation for a potential heap overflow on 32-bit systems in xmalloc.
>     CVE-2019-6438.
