MariaDB Enterprise Kubernetes Operator 25.10.5

MariaDB Enterprise Operator 25.10.5 is a Stable LTS (GA) release of MariaDB Enterprise Operator, released on 2026-05-19

Release date: 19 May 2026

If you are running in a version prior to 25.10.x, please follow the UPDATE GUIDE to ensure a safe transition.

This is a patch release which includes the following fixes:

• K8SDKR-210: Resolved a critical issue where a single failed job in a scheduled PhysicalBackup would cause a permanent deadlock, preventing any subsequent scheduled backups from executing until the failed job was manually deleted. The operator has been updated to explicitly skip failed jobs during schedule evaluation, preventing execution blocks. Additionally, backup jobs now leverage dynamic podAffinity rather than static nodeSelector pinning, allowing them to dynamically track and schedule onto whichever node the MariaDB pod is currently running on—even after node replacements or failovers. Finally, a new FailedJobsHistoryLimit configuration has been introduced to automatically clean up old failed jobs and prevent resource accumulation.
