1.6 will also default to protobuf encoding if using etcd3.  **This change is
irreversible.**  To rollback, you must restore from a backup made before the
protobuf/etcd3 switch, and any changes since the backup will be lost.  As 1.5
does not support protobuf encoding, if you roll back to 1.5 after upgrading to
protobuf you will be forced to restore from backup, and you will lose any changes
since you converted to protobuf.  After conversion to protobuf, you should

- Modified the node-local `podresources` API endpoint to consider only active pods. Since this changes long-standing behavior, the `KubeletPodResourcesListUseActivePods` feature gate (enabled by default) can be disabled to restore the previous behavior. Users encountering regressions are encouraged to file an issue if they rely on the old behavior.

### Changed

    *   Passes sourcesReady from kubelet to the device plugin to avoid removing inactive pods during the grace period of kubelet restart.
    *   Extends the gpu_device_plugin e2e_node test to verify that scheduled pods can continue to run even after a device plugin deletion and kubelet restart.
*   The NodeController no longer supports kubelet 1.2. ([#48996](https://github.com/kubernetes/kubernetes/pull/48996),[ @k82cn](https://github.com/k82cn))

### Action Required

* ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid. ([#65410](https://github.com/kubernetes/kubernetes/pull/65410), [@nikhita](https://github.com/nikhita))
