+## 0.21.1
+
+**Release date:** 2022-02-23
+
+This prerelease comes with a workaround for an
+[upstream bug in Kubernetes](https://github.com/kubernetes/kubernetes/issues/108008),
+where the keys set in a Secret with `stringData` are not removed from the cluster
+when the keys are deleted from the manifest.
+
+Improvements:
+- Convert `stringData` to `data` before applying Secrets
+  [#576](https://github.com/fluxcd/kustomize-controller/pull/576)
+- Update dependencies
+  [#574](https://github.com/fluxcd/kustomize-controller/pull/574)

-Note that due to the way [Kubernetes server-side apply](https://kubernetes.io/docs/reference/using-api/server-side-apply/)
-works, the kustomize-controller can only revert
-changes made to fields it manages. This means that `kubectl edit` changes will only be reverted if
-those fields are present in git.
+If you use kubectl to edit an object managed by Flux,
+all changes will be undone when kustomize-controller reconciles a
+Flux Kustomization containing that object.
+n order for kustomize-controller to preserve fields added with kubectl,
+you have to specify a field manager named `flux-client-side-apply` e.g.:
+
+```sh
+kubectl apply --field-manager=flux-client-side-apply

+Note that the fields defined in manifests will always be overridden,
+the above procedure works only for adding new fields that don’t overlap with the desired state.
