2.27.0¶
The Mirantis Container Cloud major release 2.27.0:
Introduces support for the Cluster release 17.2.0 that is based on the Cluster release 16.2.0 and represents Mirantis OpenStack for Kubernetes (MOSK) 24.2.
Introduces support for the Cluster release 16.2.0 that is based on Mirantis Container Runtime (MCR) 23.0.11 and Mirantis Kubernetes Engine (MKE) 3.7.8 with Kubernetes 1.27.
Does not support greenfield deployments on deprecated Cluster releases of the 17.1.x and 16.1.x series. Use the latest available Cluster releases of the series instead.
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.
