## Release notes for kOps 1.20 series
# Significant changes
* Default container runtime is now set to `containerd` for new clusters running Kubernetes 1.20.0+.
* Added experimental Azure support. To get started check the [docs](https://kops.sigs.k8s.io/getting_started/azure/)
* Default settings for AWS instances are updated to take advantage of recent performance and security features:
* Default etcd volumes encryption changes to enabled for newly created clusters
* Default root volume encryption changes to enabled
* Default etcd volumes type changes from `gp2` to `gp3`
* Default root volume type changes from `gp2` to `gp3`
* Added [template funtions](https://kops.sigs.k8s.io/operations/cluster_template/#template-functions) for kubernetes version based on channel data.
* kOps now use helm3 functions for merging template `--set` and `--values` arguments. This has slightly different behaviour than previous helm2-like logic.
* Following kubeadm, control plane nodes are now labelled with `node-role.kubernetes.io/control-plane=""`
* Default node image for GCE changed from COS to Ubuntu for K8s versions >= 1.18.0. This is to more closely align with the AWS implementation (the most mature support) and because COS limits the ability to modify files on its disk.
# Breaking changes
* Support for Kubernetes 1.11 and 1.12 has been removed.
* Support for Terraform version 0.11 has been removed.
* Support for the feature flag `Terraform-0.12` has been removed. All generated Terraform HCL2/JSON files will support versions `0.12.26+` and `0.13.0+`.
# Required Actions
* If you are using the Calico network plugin in a cross-subnet setup, you may have to manually remove the AWS Source/Dest Check controller (`k8s-ec2-srcdst`) deployment that was previously deprecated and replaced with the new [awsSrcDstCheck](https://docs.projectcalico.org/reference/resources/felixconfig#spec) feature.
* If you are using self-hosted channels files, you have to add the new `architectureID` field, with one of the `amd64` or `arm64` values.
* If you are running `kops toolbox template` in an airgapped environment, you have to set `--channel` to point to a local channel file.
* If your workload targets control plane nodes, you need to change them to select the `node-role.kubernetes.io/control-plane=""` label. You should also add the `node-role.kubernetes.io/control-plane:NoSchedule` toleration to these workloads. This taint will not be added to control plane nodes before kOps 1.22.
# Deprecations
* Support for Kubernetes versions 1.13 and 1.14 are deprecated and will be removed in kOps 1.21.
* The [manifest based metrics server addon](https://github.com/kubernetes/kops/tree/master/addons/metrics-server) has been deprecated in favour of a configurable addon.
* The [manifest based cluster autoscaler addon](https://github.com/kubernetes/kops/tree/master/addons/cluster-autoscaler) has been deprecated in favour of a configurable addon.
* The `node-role.kubernetes.io/master` and `kubernetes.io/role` labels are deprecated and will be removed from control plane nodes in kOps 1.22
* The experimental node-authorizer that could be enabled using `nodeAuthorization` has been removed. Setting this value is now forbidden.
* Due to lack of maintainers, the Aliyun/Alibaba Cloud support has been deprecated. The current implementation will be left as-is until the implementation needs updates or otherwise becomes incompatible. At that point, it will be removed. We very much welcome anyone willing to contribute to this cloud provider.
* Support for AWS LaunchConfiguration has been deprecated and will be removed in kOps 1.21.
