There are multiple supported releases, and you can upgrade from any of the last 3 releases at present, which are released every 6 months. 

Major releases are more disruptive, and there is support for the previous versions to provide continuity of support.

Hi slurm team,

I would ask some clarifications with slurm releases. Why two versions of slurm are available ?

I speak of 24.05.7 versus 24.11.3 on https://www.schedmd.com/slurm-support/release-announcements  and announces made on this list ?

I'm managing small clusters in a french public research lab and I've successfully updated (lets says re-installed as it was very old) an old one with slurm-24.05.3 some month ago.
Now I'm trying to deploy a second cluster with the same approach and I've selected 24.11.3-1 (but why not using 24.05.7 ?).

Moreover I have some difficulties for deploying 24.11.3 : I've built the rpm with:

rpmbuild \
 --define '_prefix /usr' \
 --with pmix --with ucx --with mysql --with hwloc \
 -ta slurm-24.11.3.tar.bz2

but some packages wont install:

$ dnf list --showduplicates  slurm-slurmd

Available Packages
slurm-slurmd.x86_64                                     24.11.3-1.el9                                      bb-local

$ sudo dnf install slurm-slurmd
Last metadata expiration check: 0:33:03 ago on Tue Apr  1 18:03:25 2025.
Error:
 Problem: conflicting requests
  - nothing provides is needed by slurm-slurmd-24.11.3-1.el9.x86_64 from bb-local
  - nothing provides installed needed by slurm-slurmd-24.11.3-1.el9.x86_64 from bb-local
  - nothing provides not needed by slurm-slurmd-24.11.3-1.el9.x86_64 from bb-local
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

I think I will try to build 24.05.7 or 24.05.3 as a next try but I'm interested in any advices.

Thank you

Patrick
