We are pleased to announce the availability of Slurm versions 24.05.3 and 23.11.10.

Version 24.05.3 fixes a potential database problem when deleting a qos. This bug only existed in 24.05.

Both versions have fixes for jobs potentially being stuck when using cloud nodes when some nodes are powered down, a regression in 23.11.9 and 24.05.2 that caused sattach to crash, and some other minor issues.

Slurm can be downloaded from https://www.schedmd.com/downloads.php .
