+## Urgent Upgrade Notes 
+
+### (No, really, you MUST read this before you upgrade)
+
+- external-resizer will not call controller-expand if volume is in-use and can not be expanded while in-use. New RBAC rules for listing pods are required. ([#86](https://github.com/kubernetes-csi/external-resizer/pull/86), [@gnufied](https://github.com/gnufied)) . This behaviour is enabled by default but can be disabled by setting `handle-volume-inuse-error` to `false`, which would allow external-resizer to perform volume expansion without checking if volume being expanded is in-use or not([#89](https://github.com/kubernetes-csi/external-resizer/pull/89), [@saikat-royc](https://github.com/saikat-royc)). If CSI driver being used supports online expansion, it might be desirable to set `handle-volume-inuse-error` to `false` - to save costs associated with watching all pods in the cluster.
+- The `--csiTimeout` flag of external-resizer is obsoleted with this release. Instead `--timeout` flag has been introduced for the same purpose. This timeout is used by external-resizer to decide how long it should wait for a response from CSI driver. `timeout` value defaults to 10 seconds. From now on, the deployment  templates or  artifacts has to make use of `--timeout` flag instead of obsoleted `--csiTimeout`  flag. ([#82](https://github.com/kubernetes-csi/external-resizer/pull/82), [@humblec](https://github.com/humblec))

+## Changes by Kind
+
+### Feature
+
+- Adding configurable QPS and Burst to k8s client and use a separate client for leader election. ([#91](https://github.com/kubernetes-csi/external-resizer/pull/91), [@RaunakShah](https://github.com/RaunakShah))
+
+### Bug or Regression
+
+- Ensure that we do not resize recently resized volumes ([#96](https://github.com/kubernetes-csi/external-resizer/pull/96), [@gnufied](https://github.com/gnufied))
+
+### Uncategorized
+
+- Build with Go 1.15 ([#98](https://github.com/kubernetes-csi/external-resizer/pull/98), [@pohly](https://github.com/pohly))
+- Publishing of images on k8s.gcr.io ([#84](https://github.com/kubernetes-csi/external-resizer/pull/84), [@pohly](https://github.com/pohly))

 * `--kubeconfig <path>`: Path to Kubernetes client configuration that the external-resizer uses to connect to Kubernetes API server. When omitted, default token provided by Kubernetes will be used. This option is useful only when the external-resizer does not run as a Kubernetes pod, e.g. for debugging. Either this or `--master` needs to be set if the external-resizer is being run out of cluster.
