CCE provides highly scalable, high-performance, enterprise-class Kubernetes clusters. This section describes the Kubernetes version policy of CCE clusters.

The CCE console supports clusters of the latest two commercially used versions:
- a: Clusters created using the console or APIs
- b: Clusters created only using APIs
Phases of CCE Cluster Versions
- In commercial use: The cluster version has been fully verified and is stable and reliable. You can use clusters of this version in the production environment, and the CCE SLA is valid for such clusters.
- EOS: After the cluster version EOS, CCE does not support the creation of new clusters or provide technical support including new feature updates, vulnerability or issue fixes, new patches, work order guidance, and online checks for the EOS cluster version. The CCE SLA is not valid for such clusters.
CCE Cluster Versions
CCE clusters are updated according to the versions available in the Kubernetes community. This means that a CCE cluster version is made up of both the Kubernetes community version number and the CCE patch version number. The CCE cluster version is in the format for vX.Y.Z-rN, such as v1.28.2-r0.
- A Kubernetes version is in the format of X.Y, which inherits the community version policy. The major Kubernetes version is represented by X, while the minor Kubernetes version is represented by Y. For details, see the Kubernetes version policies.
- A CCE patch version is in the format of Z-rN, for example, v1.28. New patches are released on an irregular basis for Kubernetes versions that are still in the maintenance period. If a new patch version offers new features that were not present in the previous version, the Z number will increase. If a new patch version provides bug fixes, vulnerability fixes, or scenario optimization compared to the previous version, the N number will increase.
