2.23.0

The Mirantis Container Cloud GA release 2.23.0:

• Introduces support for the Cluster release 11.7.0 that is based on Mirantis Container Runtime 20.10.13 and Mirantis Kubernetes Engine 3.5.7 with Kubernetes 1.21.

• Supports the Cluster release 12.5.0 that is based on the Cluster release 11.5.0 and represents Mirantis OpenStack for Kubernetes (MOSK) 22.5.

• Does not support greenfield deployments on deprecated Cluster releases 11.6.0, 8.10.0, and 7.11.0. Use the latest available Cluster releases of the series instead.

  Caution

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