 #### CSI raw block volume support

-{{< feature-state for_k8s_version="v1.11" state="alpha" >}}
+{{< feature-state for_k8s_version="v1.14" state="beta" >}}

 Starting with version 1.11, CSI introduced support for raw block volumes, which
 relies on the raw block volume feature that was introduced in a previous version of
 Kubernetes.  This feature will make it possible for vendors with external CSI drivers to
 implement raw block volumes support in Kubernetes workloads.

-CSI block volume support is feature-gated and turned off by default.  To run CSI with
-block volume support enabled, a cluster administrator must enable the feature for each
-Kubernetes component using the following feature gate flags:
-
-```
--feature-gates=BlockVolume=true,CSIBlockVolume=true
-```
+CSI block volume support is feature-gated, but enabled by default. The two
+feature gates which must be enabled for this feature are `BlockVolume` and
+`CSIBlockVolume`.

 Learn how to
 [setup your PV/PVC with raw block volume support](/docs/concepts/storage/persistent-volumes/#raw-block-volume-support).

-#### Developer resources
+#### CSI ephemeral volumes
+
+{{< feature-state for_k8s_version="v1.14" state="alpha" >}}
+
+This feature allows CSI volumes to be directly embedded in the Pod specification instead of a PersistentVolume. Volumes specified in this way are ephemeral and do not persist across Pod restarts.
+
+Example:
+
+```yaml
+kind: Pod
+apiVersion: v1
+metadata:
+  name: my-csi-app
+spec:
+  containers:
+    - name: my-frontend
+      image: busybox
+      volumeMounts:
+      - mountPath: "/data"
+        name: my-csi-inline-vol
+      command: [ "sleep", "1000000" ]
+  volumes:
+    - name: my-csi-inline-vol
+      csi:
+        driver: inline.storage.kubernetes.io
+        volumeAttributes:
+              foo: bar
+```
+
+This feature requires CSIInlineVolume feature gate to be enabled:
+
+```
+--feature-gates=CSIInlineVolume=true
+```
+
+CSI ephemeral volumes are only supported by a subset of CSI drivers. Please see the list of CSI drivers [here](https://kubernetes-csi.github.io/docs/drivers.html).
+
+# Developer resources
 For more information on how to develop a CSI driver, refer to the [kubernetes-csi
 documentation](https://kubernetes-csi.github.io/docs/)

+#### Migrating to CSI drivers from in-tree plugins
+
+{{< feature-state for_k8s_version="v1.14" state="alpha" >}}
+
+The CSI Migration feature, when enabled, directs operations against existing in-tree
+plugins to corresponding CSI plugins (which are expected to be installed and configured). 
+The feature implements the necessary translation logic and shims to re-route the 
+operations in a seamless fashion. As a result, operators do not have to make any 
+configuration changes to existing Storage Classes, PVs or PVCs (referring to 
+in-tree plugins) when transitioning to a CSI driver that supersedes an in-tree plugin.
+
+In the alpha state, the operations and features that are supported include 
+provisioning/delete, attach/detach and mount/unmount of volumes with `volumeMode` set to `filesystem`
+
+In-tree plugins that support CSI Migration and have a corresponding CSI driver implemented 
+are listed in the "Types of Volumes" section above.
