Docker CE / Kubernetes

Hi, i want to learn using Kubernets. In Docker CE i have installed Kubernetes and running minikube. Minikube is the latest version. But Kubernetes is version v1.10.3 ? I have seen that the latest version is v1.10.8. Does that have something to say? Is it ok to use Kubernets from docker CE ? or Is it recommended to use latest version of Kubernetes ?

Thanx for the feedback

I need to upgrade my version of k8s, but havent figured out how to do this inside the moby VM. Not sure when Docker CE will push new version with never k8s
