+## Changed
+
+### Bug Fixes
+
+* Install `cri-tools` (`crictl`) on Amazon Linux 2. This fixes the issue with provisioning Kubernetes and Amazon EKS-D clusters on Amazon Linux 2 ([#1282](https://github.com/kubermatic/kubeone/pull/1282))
+
# [v1.2.0](https://github.com/kubermatic/kubeone/releases/tag/v1.2.0) - 2021-03-18
## Attention Needed
```
For the configuration file reference, run `kubeone config print --full`.
+## Known Issues
+
+* Provisioning a Kubernetes or Amazon EKS-D cluster on Amazon Linux 2 will fail due to missing `crictl` binary. This bug has been fixed in the [v1.2.1 release](https://github.com/kubermatic/kubeone/releases/tag/v1.2.1).
+* Upgrading an Amazon EKS-D cluster will fail due to kubeadm preflight checks failing. We're investigating the issue and you can follow the progress by checking the issue [#1284](https://github.com/kubermatic/kubeone/issues/1284).
+
## Added
* Add support for Kubernetes 1.20
