If GRES are configured with file IDs, then "scontrol -d show node" will
    not only identify the count of currently allocated GRES, but their specific
    index numbers (e.g. "GresUsed=gpu:alpha:2(IDX:0,2),gpu:beta:0(IDX:N/A)").

No change in logic, just clearer messages

Added SchedulingParameters option of "bf_job_part_count_reserve". Jobs below
    the specified threshold will not have resources reserved for them.

filling up memory when the database/DBD is down.

sched/backfill plugin: Make malloc match data type (defined as uint32_t and
    allocated as int). No failures observed, if type "int" is smaller than
    "uint32_t", it could result in an invalid memory reference.

Fix API call: slurm_job_cpus_allocated_str_on_node_id() and
in turn slurm_job_cpus_allocated_str_on_node() to return correct
results for anything but first node. This was caused by missed logic
to calculate fist bit belongs to particular node. Lookup was always
starting from bit 0.

After one second of wall time, simulate the termination of all remaining
   running jobs in order to respond in a reasonable time frame.
bug 3275

Modify backfill algorithm to improve performance with large numbers of
    running jobs. Group running jobs that end in a "similar" time frame using a
    time window that grows exponentially rather than linearly. The original
    window sizes were (in units of minutes):
    0, 1, 2, 3, 4, 5, 6, 7, ... minutes
    The new window sizes are:
    0.5, 1, 2, 4, 8, 16, 32, ... minutes
    This can dramatically reduce the number of instances where the very time
    consuming "can the pending job run now" operation is executed, especailly
    if there are 1000+ running jobs.

Modify several NEWS items for greater clarity.

Dead code, except for four uses of safe_pack8 and one safe_pack16.
Convert those to the pack8/16 calls directly.

On some distributions (notably Ubuntu xenial), the mariadb client
dev package doesn't include a compatibility link for mysql_config.
This patch makes configure look for mariadb_config as an alternative
and allows building the mysql plugins against mariadb client libs.

This changes a <= to <, although it doesn't really change functionality
  in practice.

Add new PriorityFlags option of INCR_ONLY, which prevents a job's priority
    from being decremented.

Rework 84966568, 5510e7d3 so that it reduces the number

Prevent a scrollbar from appearing on the SchedMD logo in the top left.

If a node is booting for some job, don't allocate additional jobs to the
    node until the boot completes.

It isn't advised.  Do one then the other.  Basically if you are using the
mysql plugin make sure you add the cluster to the system as the mysql
plugin doesn't do that explicitly.
