+# Changelog since v1.0.1
+
+## Notable Changes
+
+- Cherry picks PR #172: Added extra verification of source PersistentVolumeClaim before creating snapshot.([#175](https://github.com/kubernetes-csi/external-snapshotter/pull/175), [@xing-yang](https://github.com/xing-yang))
+
+# Changelog since v0.4.1
+
+## Breaking Changes
+
+- Switch to use TypedLocalObjectReference in core API.([#16](https://github.com/kubernetes-csi/external-snapshotter/pull/16), [@xing-yang](https://github.com/xing-yang))
+- Update snapshotter to use CSI spec 1.0.([#58](https://github.com/kubernetes-csi/external-snapshotter/pull/58), [@msau42](https://github.com/msau42))
+- Call CreateSnapshot to check if snapshot is processed instead of ListSnapshots.([#61](https://github.com/kubernetes-csi/external-snapshotter/pull/61), [@xing-yang](https://github.com/xing-yang))
+- Bumping k8s version to 1.13.0-beta.1.([#64](https://github.com/kubernetes-csi/external-snapshotter/pull/64), [@verult](https://github.com/verult))
+- Rename `Ready` to `ReadyToUse` in the `Status` field of `VolumeSnapshot` API object.([#74](https://github.com/kubernetes-csi/external-snapshotter/pull/74), [@xing-yang](https://github.com/xing-yang))
+
+## Actions Required
+
+- CSI plugin must support the 1.0 spec. CSI spec versions < 1.0 are no longer supported.
+    - In CSI v1.0, `SnapshotStatus` is removed from `CreateSnapshotResponse`, and is replaced with a Boolean `ReadyToUse`.
+    - The snapshot controller now calls `CreateSnapshot` instead of `ListSnapshots` to check if snapshot is processed after it is cut. Driver maintainer needs to make changes accordingly in the driver.
+    - In CSI v1.0, .google.protobuf.Timestamp is used instead of int64 to represent the creation time of a snapshot. Driver maintainer needs to make changes accordingly in the driver. The creation time is visible to the admin when running `kubectl describe volumesnapshotcontent` to examine the details of a `VolumeSnapshotContent`.
+
+- The renaming from `Ready` to `ReadyToUse` in the `Status` field of `VolumeSnapshot` API object is visible to the user when running `kubectl describe volumesnapshot` to view the details of a snapshot.
+
+- External-provisioner sidecar container which depends on external-snapshotter APIs needs to be updated whenever there is an API change in external-snapshotter. Compatible sidecar container images for external-provisioner and external-snapshotter need to be used together, i.e., both are v1.0.0 or both are v1.0.1.
+
+## Deprecations
+
+- The following VolumeSnapshotClass parameters are deprecated and will be removed in a future release:
+
