</Warning>

## New features

This release introduces several enhancements across multiple components. The accounting system now includes `sacctmgr ping` as readiness and liveness probe for improved health monitoring. Resource management has been enhanced with separate `slurm-login` pod resource defaults, and job processing now supports skipping specific job IDs when needed.

The Helm charts have received numerous improvements including default `sshd` configuration for login services, default `UnkillableStepProgram` integration in the Slurm chart, and `NVIDIA_DRIVER_CAPABILITIES` set to `all` for compute pods. The sunk controller now includes priority class configuration, and node cleanup is enabled by default in the Slurm Chart. Individual login services can now have metadata set separately, and MySQL memory requests have been updated to `64Gi` in `values-cw` within the slurm chart.

The operator component now supports `allowgaps` in `topology.conf` and exports additional sunk metrics. The Syncer has been enhanced with node state metrics and improved reboot functionality using `production-powerreset`, while the HooksAPI endpoint has been refactored to accept safe reboot requests. Affinity merging is now supported, and the system has been upgraded to Slurm 24.11 for enhanced performance and stability.

## Removed components

Several components have been removed from the codebase including Sentry integration from the operator, Slurm-login codebase, and all related charts. The Slurm-login component has been updated with meta %h support for username hashing.
