SLURM versions 2.2.4 and 2.3.0-pre4 are now available form SourceForge:
https://sourceforge.net/projects/slurm/files/
Version 2.2.4 contains a variety of bug fixes as noted below.
Verion 2.3.0-pre4 includes the bug fixes found in version 2.2.4 plus many
enhancements, but should be considered still under development and not
intended for production use.

* Changes in SLURM 2.2.4
========================
-- For batch jobs for which the Prolog fails, substitute the job ID for any
"%j" in the job's output or error file specification.
-- Add licenses field to the sview reservation information.
-- BLUEGENE - Fix for handling extremely overloaded system on Dynamic system
dealing with starting jobs on overlapping blocks. Previous fallout
was job would be requeued. (happens very rarely)
-- In accounting_storage/filetxt plugin, substitute spaces within job names,
step names, and account names with an underscore to insure proper parsing.
-- When building contribs/perlapi ignore both INSTALL_BASE and PERL_MM_OPT.
Use PREFIX instead to avoid build errors from multiple installation
specifications.
-- Add job_submit/cnode plugin to support resource reservations of less than
a full midplane on BlueGene computers. Treat cnodes as liceses which can
be reserved and are consumed by jobs. This reservation mechanism for less
than an entire midplane is still under development.
-- Clear a job's "reason" field when a held job is released.
-- When releasing a held job, calculate a new priority for it rather than
just setting the priority to 1.
-- Fix for sview started on a non-bluegene system to pick colors correctly
when talking to a real bluegene system.
-- Improve sched/backfill's expected start time calculation.
-- Prevent abort of sacctmgr for dump command with invalid (or no) filename.
-- Improve handling of job updates when using limits in accounting, and
updating jobs as a non-admin user.
-- Fix for "squeue --states=all" option. Bug would show no jobs.
-- Schedule jobs with reservations before those without reservations.
-- Fix squeue/scancel to query correctly against accounts of different case.
-- Abort an srun command when it's associated job gets aborted due to a
dependency that can not be satisfied.
-- In jobcomp plugins, report start time of zeroif pending job is cancelled.
Previously may report expected start time.
-- Fixed sacctmgr man to state correct variables.
-- Select nodes based upon their Weight when job allocation requests include
a constraint field with a count (e.g. "srun --constraint=gpu*2 -N4 a.out").
-- Add support for user names that are entirely numeric and do not treat them
as UID values. Patch from Dennis Leepow.
-- Patch to un/pack double values properly if negative value. Patch from
Dennis Leepow.
-- Do not reset a job's priority when requeued or suspended.
-- Fix problemm that could let new jobs start on a node in DRAINED state.
-- Fix cosmetic sacctmgr issue where if the user you are trying to add
doesn't exist in the /etc/passwd file and the account you are trying
to add them to doesn't exist it would print (null) instead of the bad
account name.
-- Fix associations/qos for when adding back a previously deleted object
the object will be cleared of all old limits.
-- BLUEGENE - Added back a lock when creating dynamic blocks to be more thread
safe on larger systems with heavy load.
* Changes in SLURM 2.3.0.pre4
=============================
-- Add GraceTime to Partition and QOS data structures. Preempted jobs will be
given this time interval before termination. Work by Bill Brophy, Bull.
-- Add the ability for scontrol and sview to modify slurmctld DebugFlags
values.
-- Various Cray-specific patches:
- Fix a bug in distinguishing XT from XE.
- Avoids problems with empty nodenames on Cray.
- Check whether ALPS is hanging on to nodes, which happens if ALPS has not
yet cleaned up the node partition.
- Stops select/cray from clobbering node_ptr->reason.
- Perform 'safe' release of ALPS reservations using inventory and apkill.
- Compile-time sanity check for the apbasil and apkill files.
- Changes error handling in do_basil_release() (called by
select_g_job_fini()).
- Warn that salloc --no-shell option is not supported on Cray systems.
-- Add a reservation flag of "License_Only". If set, then jobs using the
reservation may use the licenses associated with it plus any compute nodes.
Otherwise the job is limited to the compute nodes associated with the
reservation.
-- Change slurm.conf node configuration parameter from "Procs" to "CPUs".
Both parameters will be supported for now.
-- BLUEGENE - fix for when user requests only midplane names with no count at
job submission time to process the node count correctly.
-- Fix job step resource allocation problem when both node and tasks counts
are specified. New logic selects nodes with larger CPU counts as needed.
-- BGQ - make it so srun wraps runjob (still under construction, but works
for most cases)
-- Permit a job's QOS and Comment field to both change in a single RPC. This
was previously disabled since Moab stored the QOS within the Comment field.
-- Add support for jobs to expand in size. Submit additional batch job with
the option "--dependency=expand:<jobid>". See web page "faq.html#job_size"
for details. Restrictions to be removed in the future.
-- Added --with-alps-emulation to configure, and also an optional cray.conf
to setup alps location and database information.
-- Modify PMI data types from 16-bits to 32-bits in order to support MPICH2
jobs with more than 65,536 tasks. Patch from Hongjia Cao, NUDT.
-- Set slurmd's soft process CPU limit equal to it's hard limit and notify the
user if the limit is not infinite.
-- Added proctrack/cgroup and task/cgroup plugins from Matthieu Hautreux, CEA.
-- Fix slurmctld restart logic that could leave nodes in UNKNOWN state for a
longer time than necessary after restart.
