+## Features
+### Make workspace PVC's Access mode configurable [#1019](https://github.com/devfile/devworkspace-operator/issues/1019)
+It is now possible to configure the storage access mode of per-user and per-workspace PVCs from the global `DevWorkspaceOperatorConfig`. For example:
+```
+apiVersion: controller.devfile.io/v1alpha1
+kind: DevWorkspaceOperatorConfig
+metadata:
+  name: devworkspace-operator-config
+  namespace: $OPERATOR_INSTALL_NAMESPACE
+config:
+  workspace:
+    imagePullPolicy: Always
+    storageAccessMode:
+    - ReadWriteMany
+```
+
