CCE Cluster Version Releases

[artem-lifshits]

To ensure that stable and reliable Kubernetes versions are available during your use of CCE, CCE provides the Kubernetes version support mechanism. A new supported version will be released every half a year with a support period of one year. You must upgrade your Kubernetes clusters before the support period ends.
