clean up sockets at step termination. * Fix 'scontrol hold' to work with 'JobName'. * sbatch - handle --uid/--gid in #SBATCH directives properly. * Fix race condition in job termination on slurmd. * Print specific error messages if trying to run use certain priority/multifactor factors that cannot work without SlurmDBD. * Avoid partial GRES allocation when --gpus-per-job is not satisfied. * Cray - Avoid referencing a variable outside of it's correct scope when dealing with creating steps within a het job. * slurmrestd - correctly handle larger addresses from accept(). * Avoid freeing wrong pointer with SlurmctldParameters=max_dbd_msg_action with another option after that. * Restore MCS label when suspended job is resumed. * Fix insufficient lock levels. * slurmrestd - use errno from job submission. * Fix 'user' filter for sacctmgr show transactions. * Fix preemption logic. * Fix no_consume GRES for exclusive (whole node) requests. * Fix regression in 20.02 that caused an infinite loop in slurmctld when requesting --distribution=plane for the job. * Fix parsing of the --distribution option. * Add CONF READ_LOCK to _handle_fed_send_job_sync. * prep/script - always call slurmctld PrEp callback in _run_script(). * Fix node estimation for jobs that use GPUs or --cpus-per-task. * Fix jobcomp, job_submit and cli_filter Lua implementation plugins causing slurmctld and/or job submission CLI tools segfaults due to bad return handling when the respective Lua script failed to load. * Fix propagation of gpu options through hetjob components. * Add SLURM_CLUSTERS environment variable to scancel. * Fix packing/unpacking of 'unlinked' jobs. * Connect slurmstepd's stderr to srun for steps launched with --pty. * Handle MPS correctly when doing exclusive allocations. * slurmrestd -

changed the 'PROMISCUOUS' flag to 'MAGNETIC' * Early return from epilog_set_env in case of no_consume. * Fix cons_common/job_test start time discovery logic to prevent skewed results between 'will run test' executions. * Ensure TRESRunMins limits are maintained during 'scontrol reconfigure'. * Improve error message when host lookup fails.
