> * Changes in Slurm 17.11.4
> ==========================
>  -- Add fatal_abort() function to be able to get core dumps if we hit an
>     "impossible" edge case.
>  -- Link slurmd against all libraries that slurmstepd links to.
>  -- Fix limits enforce order when they're set at partition and other levels.
>  -- Add slurm_load_single_node() function to the Perl API.
>  -- slurm.spec - change dependency for --with lua to use pkgconfig.
>  -- Fix small memory leaks in node_features plugins on reconfigure.
>  -- slurmdbd - only permit requests to update resources from operators or
>     administrators.
>  -- Fix handling of partial writes in io_init_msg_write_to_fd() which can
>     lead to job step launch failure under higher cluster loads.
>  -- MYSQL - Fix to handle quotes in a given work_dir of a job.
>  -- sbcast - fix a race condition that leads to "Unspecified error".
>  -- Log that support for the ChosLoc configuration parameter will end in Slurm
>     version 18.08.
>  -- Fix backfill performance issue where bf_min_prio_reserve was not respected.
>  -- Fix MaxQueryTimeRange checks.
>  -- Print MaxQueryTimeRange in "sacctmgr show config".
>  -- Correctly check return codes when creating a step to check if needing to
>     wait to retry or not.
>  -- Fix issue where a job could be denied by Reason=MaxMemPerLimit when not
>     requesting any tasks.
>  -- In perl tools, fix for regexp that caused extra incorrectly shown results.
>  -- Add some extra locks in fed_mgr to be extra safe.
>  -- Minor memory leak fixes in the fed_mgr on slurmctld shutdown.
>  -- Make sreport job reports also report duplicate jobs correctly.
>  -- Fix issues restoring certain Partition configuration elements, especially
>     when ReconfigFlags=KeepPartInfo is enabled.
>  -- Don't add TRES whose value is NO_VAL64 when building string line.
>  -- Fix removing array jobs from hash in slurmctld.
>  -- Print out missing user messages from jobsubmit plugin when srun/salloc are
>     waiting for an allocation.
>  -- Handle --clusters=all as case insensitive.
>  -- Only check requested clusters in federation when using --test-only
>     submission option.
>  -- In the federation, make it so you can cancel stranded sibling jobs.
>  -- Silence an error from PSS memory stat collection process.
>  -- Requeue jobs allocated to nodes requested to DRAIN or FAIL if nodes are
>     POWER_SAVE or POWER_UP, preventing jobs to start on NHC-failed nodes.
>  -- Make MAINT and OVERLAP resvervation flags order agnostic on overlap test.
>  -- Preserve node features when slurmctld daemons reconfigured including active
>     and available KNL features.
>  -- Prevent creation of multiple io_timeout threads within srun, which can
>     lead to fatal() messages when those unexpected and additional mutexes are
>     destroyed when srun shuts down.
>  -- burst_buffer/cray - Prevent use of "#DW create_persistent" and
>     "#DW destroy_persistent" directives available in Cray CLE6.0UP06. This
>     will be supported in Slurm version 18.08. Use "#BB" directives until then.
>  -- Fix task/cgroup affinity to behave correctly.
>  -- FreeBSD - fix build on systems built with WITHOUT_KERBEROS.
>  -- Fix to restore pn_min_memory calculated result to correctly enforce
>     MaxMemPerCPU setting on a partition when the job uses --mem.
>  -- slurmdbd - prevent infinite loop if a QOS is set to preempt itself.
>  -- Fix issue with log rotation for slurmstepd processes.
