## 2.2.0 (2018-08-30)

### Notes about upgrading from v2.1

* The `argo install` and `argo uninstall` commands have been removed from the CLI. Instead, plain
kubernetes manifests are provided to be installed using `kubectl apply`, or downstreamed into other
tools (e.g. helm chart, ksonnet prototype, kustomize, etc...).
* In 2.1, argo would install into the kube-system namespace by default. The new install instructions
have been updated to install into a different namespace, `argo`. In order to move to the recommended
installation location, you should delete the v2.1 resources from kube-system before applying the
new manifests to the `argo` namespace.

    The following commands migrates the workflow-controller-configmap from the `kube-system` to the
`argo` namespace, and deletes all argo resources from the `kube-system` namespace. Note that this
will delete the argo-ui service, resulting in the LoadBalancer being deleted (if created).

    ```
    kubectl get cm workflow-controller-configmap -o yaml -n kube-system --export | kubectl apply -n argo -f -
    kubectl delete -n kube-system cm workflow-controller-configmap
    kubectl delete -n kube-system deploy workflow-controller argo-ui
    kubectl delete -n kube-system sa argo argo-ui
    kubectl delete -n kube-system svc argo-ui
    ```

* In 2.1, the argoexec sidecar image was configured in the workflow-controller-configmap. This is
now configured using a new `--executor-image` flag in the `workflow-controller` deployment. This is
the preferred way to configure the executor image, since upgrades can now be performed without
changing the workflow-controller configmap. The executorImage setting in the config is deprecated
and may be removed/ignored in a future release.
