+## Urgent Upgrade Notes 
+
+### (No, really, you MUST read this before you upgrade)
+
+- Update volumeAttachment to v1
+
+  RBAC policy was updated to allow the external-attacher to patch VolumeAttachment.Status ([#200](https://github.com/kubernetes-csi/external-attacher/pull/200), [@cwdsuzhou](https://github.com/cwdsuzhou))
+ - Use GA version of CSINode object. The external-attacher now requires Kubernetes 1.17. ([#193](https://github.com/kubernetes-csi/external-attacher/pull/193), [@bertinatto](https://github.com/bertinatto))
+
+## Changes by Kind
+
+### Feature
+
+- Added support for migration of Kubernetes in-tree VMware volumes to CSI. ([#236](https://github.com/kubernetes-csi/external-attacher/pull/236), [@divyenpatel](https://github.com/divyenpatel))
+
+### Bug or Regression
+
+- Fixes an issue in volume attachment reconciler when the CSI driver supports LIST_VOLUMES_PUBLISHED_NODES but does not implement CSI migration. ([#244](https://github.com/kubernetes-csi/external-attacher/pull/244), [@yuga711](https://github.com/yuga711))
+- Use dedicated Kubernetes client for leader election that does not get throttled when the external-attacher is under heavy load. ([#242](https://github.com/kubernetes-csi/external-attacher/pull/242), [@jsafrane](https://github.com/jsafrane))
+
+### Other (Cleanup or Flake)
+
+- Removed support of go dep. ([#239](https://github.com/kubernetes-csi/external-attacher/pull/239), [@jsafrane](https://github.com/jsafrane))
+
+### Uncategorized
+
+- Build with Go 1.15 ([#246](https://github.com/kubernetes-csi/external-attacher/pull/246), [@pohly](https://github.com/pohly))
+- Publishing of images on k8s.gcr.io ([#231](https://github.com/kubernetes-csi/external-attacher/pull/231), [@pohly](https://github.com/pohly))
+- Updated client-go to v0.18 ([#221](https://github.com/kubernetes-csi/external-attacher/pull/221), [@humblec](https://github.com/humblec))

+The external-attacher is a sidecar container that attaches volumes to nodes by calling `ControllerPublish` and `ControllerUnpublish` functions of CSI drivers. It is necessary because internal Attach/Detach controller running in Kubernetes controller-manager does not have any direct interfaces to CSI drivers.
 
 ## Terminology
 
@@ -13,15 +13,16 @@ In Kubernetes, the term *attach* means 3rd party volume attachment to a node. Th
 It is **not** an attach/detach operation performed by a code running on a node, such as an attachment of iSCSI or Fibre Channel volumes. These are typically performed during `NodeStage` and `NodeUnstage` CSI calls and are not done by the external-attacher.
 
 ## Overview
+
 The external-attacher is an external controller that monitors `VolumeAttachment` objects created by controller-manager and attaches/detaches volumes to/from nodes (i.e. calls `ControllerPublish`/`ControllerUnpublish`. Full design can be found at Kubernetes proposal at [container-storage-interface.md](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/storage/container-storage-interface.md)

 * `--csi-address <path to CSI socket>`: This is the path to the CSI driver socket inside the pod that the external-attacher container will use to issue CSI operations (`/run/csi/socket` is used by default).
 
 * `--leader-election`: Enables leader election. This is useful when there are multiple replicas of the same external-attacher running for one CSI driver. Only one of them may be active (=leader). A new leader will be re-elected when current leader dies or becomes unresponsive for ~15 seconds.

 ### CSI error and timeout handling
+
 The external-attacher invokes all gRPC calls to CSI driver with timeout provided by `--timeout` command line argument (15 seconds by default).
 
 * `ControllerPublish`: The call might have timed out just before the driver attached a volume and was sending a response. From that reason, timeouts from `ControllerPublish` is considered as "*volume may be attached*" or "*volume is being attached in the background*." The external-attacher will re-try calling `ControllerPublish` after exponential backoff until it gets either successful response or final (non-timeout) error that the volume cannot be attached.
@@ -92,6 +96,7 @@ The external-attacher invokes all gRPC calls to CSI driver with timeout provided
 Correct timeout value depends on the storage backend and how quickly it is able to processes `ControllerPublish` and `ControllerUnpublish` calls. The value should be set to accommodate majority of them. It is fine if some calls time out - such calls will be re-tried after exponential backoff (starting with `--retry-interval-start`), however, this backoff will introduce delay when the call times out several times for a single volume (up to `--retry-interval-max`).
 
 ### Periodic re-sync
+
 When CSI driver supports `LIST_VOLUMES` and `LIST_VOLUMES_PUBLISHED_NODES` capabilities, the external attacher periodically syncs volume attachments requested by Kubernetes with the actual state reported by CSI driver. Volumes detached by any 3rd party, but still required to be attached by Kubernetes, will be re-attached back. Frequency of this re-sync is controlled by `--reconcile-sync` command line parameter.
