Important: MSR 2.9.x reaches End of Life (EOL) on 2026-DEC-01. Mirantis strongly recommends upgrading to the latest supported version to continue receiving updates, fixes, and support.

Warning

MKE 3.4.1 was discontinued shortly after release due to an issue that prevents service creation from MKE client bundles and CI/CD pipeline deployment. This issue can interrupt MSR availability. The new features, product enhancements, and bug fixes planned for MKE 3.4.1 are a part of MKE 3.4.2, which also resolves the service prevention issue.

Mirantis strongly recommends that customers who deployed MKE 3.4.1 upgrade to MKE 3.4.2.
