* 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.
