- When a CNI plugin returns dual-stack pod IPs, kubelet will now try to respect the
  "primary IP family" of the cluster by picking a primary pod IP of the same family

- Updated static pods are restarted 2s faster by correcting a safe but non-optimal ordering bug. ([#116690](https://github.com/kubernetes/kubernetes/pull/116690), [@smarterclayton](https://github.com/smarterclayton))...

- The --storage-versions flag of kube-apiserver is now deprecated. This flag should be omitted to ensure the default storage versions are used. Otherwise the cluster is not safe to upgrade to a version newer than 1.12. This flag will be removed in 1.13.

    *   The default admin and edit roles now include read/write permissions
    *   The view role includes read permissions on poddisruptionbudget.policy resources.
*   RBAC rules can now match the same subresource on any resource using the form `*/(subresource)`. For example, `*/scale` matches requests to `replicationcontroller/scale`. ([#53722](https://github.com/kubernetes/kubernetes/pull/53722),[ @deads2k](https://github.com/deads2k))

### Storage
- Bump CSI version to 1.2.0 ([#84832](https://github.com/kubernetes/kubernetes/pull/84832), [@gnufied](https://github.com/gnufied))
- CSI Migration: Fixes issue where all volumes with the same inline volume inner spec name were staged in the same path. Migrated inline volumes are now staged at a unique path per unique volume. ([#84754](https://github.com/kubernetes/kubernetes/pull/84754), [@davidz627](https://github.com/davidz627))

- Reverts breaking change to inline AzureFile volumes in v1.18.15-v1.18.17; referenced secrets are now correctly searched for in the same namespace as the pod as in previous releases. ([#100397](https://github.com/kubernetes/kubernetes/pull/100397), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

* fix CreateVolume func: use search mode instead ([#54687](https://github.com/kubernetes/kubernetes/pull/54687), [@andyzhangx](https://github.com/andyzhangx))
* remove time waiting after create storage account (save 25s) ([#56679](https://github.com/kubernetes/kubernetes/pull/56679), [@andyzhangx](https://github.com/andyzhangx))
