+# Release notes for v4.1.0
+
+# Changelog since v4.0.2
+
+## Changes by Kind
+
+### Feature
+ - Mock driver: optionally proxy connections instead of handling them directly ([#314](https://github.com/kubernetes-csi/csi-test/pull/314), [@pohly](https://github.com/pohly))
+ - csi-sanity: clean up sourced volumes prior to deleting sourcing resources ([#297](https://github.com/kubernetes-csi/csi-test/pull/297), [@timoreimann](https://github.com/timoreimann))
+
+### Bug or Regression
+ - Add kubelet pod and csi plugin directories to mock driver manifest ([#308](https://github.com/kubernetes-csi/csi-test/pull/308), [@msau42](https://github.com/msau42))
+ - Log output from klog/v2 at higher log levels is now available ([#313](https://github.com/kubernetes-csi/csi-test/pull/313), [@pohly](https://github.com/pohly))
+ - Mock driver: fix formatting of error message for invalid starting token ([#322](https://github.com/kubernetes-csi/csi-test/pull/322), [@pohly](https://github.com/pohly))
+ - Updates the mock driver to create the target directory in `NodePublishVolume`, and remove it in `NodeUnpublishVolume`. ([#303](https://github.com/kubernetes-csi/csi-test/pull/303), [@huffmanca](https://github.com/huffmanca))
+
+### Other (Cleanup or Flake)
