* Changes in Slurm 21.08.7
==========================
-- openapi/v0.0.37 - correct calculation for bf_queue_len_mean in /diag.
-- Optimize sending down nodes in maintenance mode to the database when
removing reservations.
-- Avoid shrinking a reservation when overlapping with downed nodes.
-- Fix 'planned time' in rollups for jobs that were still pending when the
rollup happened.
-- Prevent new elements from a job array from causing rerollups.
-- Only check TRES limits against current usage for TRES requested by the job.
-- Do not allocate shared gres (MPS) in whole-node allocations
-- Fix minor memory leak when dealing with configless setups.
-- Constrain slurmstepd to job/step cgroup like in previous versions of Slurm.
-- Fix warnings on 32-bit compilers related to printf() formats.
-- Fix memory leak when freeing kill_job_msg_t.
-- Fix memory leak when using data_t.
-- Fix reconfigure issues after disabling/reenabling the GANG PreemptMode.
-- Fix race condition where a cgroup was being deleted while another step
was creating it.
-- Set the slurmd port correctly if multi-slurmd
-- openapi/v0.0.37 - Fix misspelling of account_gather_frequency in spec.
-- openapi/v0.0.37 - Fix misspelling of cluster_constraint in spec.
-- Fix FAIL mail not being sent if a job was cancelled due to preemption.
-- slurmrestd - move debug logs for HTTP handling to be gated by debugflag
NETWORK to avoid unnecessary logging of communication contents.
-- Fix issue with bad memory access when shrinking running steps.
-- Fix various issues with internal job accounting with GRES when jobs are
shrunk.
-- Fix ipmi polling on slurmd reconfig or restart.
-- Fix srun crash when reserved ports are being used and het step fails
to launch.
-- openapi/dbv0.0.37 - fix DELETE execution path on /user/{user_name}.
-- slurmctld - Properly requeue all components of a het job if PrologSlurmctld
fails.
-- rlimits - remove final calls to limit nofiles to 4096 but to instead use
the max possible nofiles in slurmd and slurmdbd.
-- Fix slurmctld memory leak after a reconfigure with configless.
-- Fix slurmd memory leak when fetching configless files.
-- Allow the DBD agent to load large messages (up to MAX_BUF_SIZE) from state.
-- Fix minor memory leak with cleaning up the extern step.
-- Fix potential deadlock during slurmctld restart when there is a completing
job.
-- slurmstepd - reduce user requested soft rlimits when they are above max
hard rlimits to avoid rlimit request being completely ignored and
processes using default limits.
-- Fix memory leaks when job/step specifies a container.
-- Fix Slurm user commands displaying available features as active features
when no features were active.
-- Don't power down nodes that are rebooting.
-- Clear pending node reboot on power down request.
