+# v1.1.0 - Changelog since v1.0.0
+
+## Changes by Kind
+
+## Feature
+
+- Improved Windows Support
+  - Update driver to use CSI proxy beta for Windows ([#607](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/607), [@jingxu97](https://github.com/jingxu97))
+  - Add volume expansion support for Windows in GCE PD CSI driver ([#637](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/637), [@jingxu97](https://github.com/jingxu97))
+  - Add defensive check for Windows. GCE PD CSI driver only support ntfs for Windows. If other fstype is passed, return error. ([#641](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/641), [@jingxu97](https://github.com/jingxu97))
+  - Modify NodeUnstageVolume call for Windows to use csi_proxy dismount call. With CSI proxy v0.2.2+, this will also result in flush of data cache before mount point removal. ([#633](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/633), [@jingxu97](https://github.com/jingxu97))
+  - Add VolumeStats for Windows ([#627](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/627), [@jingxu97](https://github.com/jingxu97))

+- Update GCE PD CSI Driver Docker base image to `k8s.gcr.io/build-image/debian-base-amd64:v2.1.3` (previously `gcr.io/google-containers/debian-base-amd64:v2.0.0`) to address CVEs. ([#596](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/596), [@saad-ali](https://github.com/saad-ali))
+  - Also cherry picked to 1.0.1.

+## Tests
+
+- PD CSI e2e test infra should take GKE node version as an optional input argument. ([#603](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/603), [@saikat-royc](https://github.com/saikat-royc))
+- Collect managed pd csi driver logs from node ([#619](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/619), [@saikat-royc](https://github.com/saikat-royc))

+- Enable volume expansion test for GKE managed driver ([#584](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/584), [@saikat-royc](https://github.com/saikat-royc))
+- Provide a knob to run intree and csi plugin tests ([#629](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/629), [@saikat-royc](https://github.com/saikat-royc))
+- Fix CI script focus string ([#630](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/630), [@saikat-royc](https://github.com/saikat-royc))
+- Build only linux container image for tests on Linux  ([#636](https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/pull/636), [@jingxu97](https://github.com/jingxu97))
