- You can now have different operation names for different storage operations. This still prevents two operations on same volume from happening concurrently but if the operation changes, it resets the exponential backoff.

- List operations against the API now return internal server errors instead of partially complete lists when a value cannot be transformed from storage. The updated behavior is consistent with all other operations that require transforming data from storage such as watch and get.

With the release of Kubernetes 1.18, an alpha version of CSI Proxy for Windows is getting released. CSI proxy enables non-privileged (pre-approved) containers to perform privileged storage operations on Windows. CSI drivers can now be supported in Windows by leveraging CSI proxy.
SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:

* Time for attach/detach retry operations has been decreased from 10-12s to 2-6s ([#56974](https://github.com/kubernetes/kubernetes/pull/56974), [@gnufied](https://github.com/gnufied))

### Auth

* Contexts must be named in kubeconfigs. ([#56769](https://github.com/kubernetes/kubernetes/pull/56769), [@dixudx](https://github.com/dixudx))

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89239](https://github.com/kubernetes/kubernetes/pull/89239), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]

* Use separate client for leader election in scheduler to avoid starving leader election by regular scheduler operations. ([#53793](https://github.com/kubernetes/kubernetes/pull/53793), [@wojtek-t](https://github.com/wojtek-t))

    * of DaemonSet Pod already exists, it will be replaced.
    * DaemonSet controller will only perform these operations when creating DaemonSet Pods;
    * and those operations will only modify the Pods of DaemonSet, no changes are made to the
    * `.spec.template` of DaemonSet.

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89240](https://github.com/kubernetes/kubernetes/pull/89240), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]
