2.29.0

The Mirantis Container Cloud major release 2.29.0:

• Introduces support for the Cluster release 17.4.0 that is based on the Cluster release 16.4.0 and represents MOSK 25.1.

• Introduces support for the Cluster release 16.4.0 that is based on Mirantis Container Runtime (MCR) 25.0.8 and Mirantis Kubernetes Engine (MKE) 3.7.19 with Kubernetes 1.27.

• Does not support greenfield deployments on deprecated Cluster releases of the 17.3.x and 16.3.x series. 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.
