MariaDB Enterprise Kubernetes Operator 26.03.1

MariaDB Enterprise Operator 26.03.1 is a Stable (GA) release of MariaDB Enterprise Operator, released on 2026-03-13

Release date: 13 March 2026

If you are running in a version prior to 26.03.x, please follow the UPDATE GUIDE to ensure a safe transition.

This is a patch release which includes the following fixes:

• K8SDKR-168: Transparent Data Encryption (TDE) is now compatible with physical backups managed by the PhysicalBackup resource. The operator propagates the env, volumes and volumeMounts from the MariaDB resource to the PhysicalBackup jobs. This allows the backup jobs to have access to the TDE key and the VAULT_TOKEN environment variable, so mariadb-backup can function normally with TDE enabled.
