EulerOS 2.9 reached end-of-maintenance on December 31, 2025. We continued to provide updates beyond the standard support window, up until our June update (BM#3), but starting with this August update (BM#4), we will no longer deliver updates for EulerOS 2.9.

If you are running EulerOS 2.9, please migrate to HCE OS 2 or Ubuntu 22.04 to receive future security patches and kernel updates.

Perform a node rollout or node reset to ensure all nodes run the most current kernel and packages with security fixes applied.
