I'd write:
| - In Kubernetes version 1.21 kube-dns usage with kubeadm has been removed | |
| - In Kubernetes version 1.21 support for using `kube-dns` with kubeadm was removed. | |
| You can use CoreDNS with kubeadm even where the related Service is named `kube-dns`. |
and I'd put that statement at the end of the list. Readers are likely to be more interested in what is supported.
