We would like to upgrade the Kubernetes version to \>=1.15.2. Currently, we are running the replicated version `2.48.0` in our cluster. As per [replicated Kubernetes Documentation](https://help.replicated.com/docs/kubernetes/customer-installations/installing/#compatible-kubernetes-versions) replicated version \>= 2.38.0 is pinned/hardcoded with 1.15.3. Re-running `install.sh` script with `kubernetes-upgrade-patch-version` also doesn’t make any difference. Following [Official Kubernetes Upgrade documentation](https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/) also doesn’t help.  
It would be a great help if there are ways to upgrade the Kubernetes cluster to the latest stable version(1.19+) or at least 1.18+.

1.15.3 is the latest version of Kubernetes available with Replicated currently, but 1.15.12 will be available in an upcoming release.

@areed as per the [Announcement in Kubernetes community forum.](https://discuss.kubernetes.io/t/security-advisory-cve-2019-11254-denial-of-service-vulnerability-from-malicious-yaml-payloads/10345) Kubernetes versions \< 1.15.10 / 1.16.x \< 1.16.7 / 1.17.x \< 1.17.3 are prone to DOS attacks. So we might need to address the issue by upgrading ASAP. An idea on a release date would help us to plan the activities well in advance and to communicate with the customer as well.

Thanks a lot @dmitriy. I hope future releases will target Kubernetes versions 1.16.x \< 1.16.7 / 1.17.x \< 1.17.3
