14.1.0

This section outlines release notes for the Cluster release 14.1.0 that is introduced in the Container Cloud release 2.25.0. This Cluster release is dedicated for the vSphere provider only. This is the last Cluster release for the vSphere provider based on Mirantis Kubernetes Engine 3.6.6 with Kubernetes 1.24.

Important

The major Cluster release 14.1.0 is the last Cluster release for the vSphere provider based on MCR 20.10 and MKE 3.6.6 with Kubernetes 1.24. Therefore, Mirantis highly recommends updating your existing vSphere-based managed clusters to the Cluster release 16.0.1 that contains newer versions on MCR and MKE with Kubernetes. Otherwise, your management cluster upgrade to Container Cloud 2.25.2 will blocked.

For the update procedure, refer to Operations Guide: Update a patch Cluster release of a managed cluster.

Since Container Cloud 2.25.1, the major Cluster release 14.1.0 is deprecated. Greenfield vSphere-based deployments on this Cluster release are not supported. Use the patch Cluster release 16.0.1 for new deployments instead.
