+
+### Bug or Regression
+ - Fix capacity information updates when topology changes. Only affected central deployment and network attached storage, not deployment on each node. This broke in v2.2.0 as part of a bug fix for capacity informer handling. ([#617](https://github.com/kubernetes-csi/external-provisioner/pull/617), [@bai3shuo4](https://github.com/bai3shuo4))
+ - Fixed reporting of metrics when a migratable CSI driver is used. ([#620](https://github.com/kubernetes-csi/external-provisioner/pull/620), [@jsafrane](https://github.com/jsafrane))
