2.14.0

The Mirantis Container Cloud GA release 2.14.0:

• Introduces support for the Cluster release 7.4.0 that is based on Mirantis Container Runtime 20.10.6 and the updated version of Mirantis Kubernetes Engine 3.4.6 with Kubernetes 1.20.

• Introduces support for the Cluster release 5.21.0 that is based on the updated version of Mirantis Kubernetes Engine 3.3.13 with Kubernetes 1.18 and Mirantis Container Runtime 20.10.6.

• Supports the Cluster release 6.20.0 that is based on the Cluster release 5.20.0 and represents Mirantis OpenStack for Kubernetes (MOS) 21.6.

• Supports deprecated Cluster releases 5.20.0, 6.19.0, and 7.3.0 that will become unsupported in the following Container Cloud releases.

  Caution

  Make sure to update the Cluster release version of your managed cluster before the current Cluster release version becomes unsupported by a new Container Cloud release version. Otherwise, Container Cloud stops auto-upgrade and eventually Container Cloud itself becomes unsupported.
