Kubernetes patch versions contain bug fixes and security vulnerability patches for a Kubernetes minor version. They are compatible with each other within the same minor version.

If automatic patch version updates are enabled, the cluster will be updated to the latest available patch version during the next cluster maintenance window.

You can enable automatic patch version updates when creating a cluster or for an already created cluster.

In the control panel, on the top menu, click Products and select Managed Kubernetes.
In the Clusters section, open the cluster page → Settings tab.
In the Automation block, enable auto-update for patch versions.
