- Fixed missing delete events on informer re-lists to ensure all delete events were correctly emitted and using the latest known object state, so that all event handlers and stores always reflect the actual apiserver state as best as possible ([#115620](https://github.com/kubernetes/kubernetes/pull/115620), [@odinuge](https://github.com/odinuge))

EBS support across the board. If a Volume is “stuck” in the attaching state to a node for too long a unschedulable taint will be applied to the node, so a Kubernetes admin can [take manual steps to correct the error](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-attaching-volume.html). Users are encouraged to ensure they are monitoring for the taint, and should consider automatically terminating instances in this state.

In addition, support for NVMe disks has been added to Kubernetes,...

* GCE: Fixes ILB sync on legacy networks and auto networks with unique subnet names ([#53410](https://github.com/kubernetes/kubernetes/pull/53410), [@nicksardo](https://github.com/nicksardo))
* Fix the bug that query Kubelet's stats summary with CRI stats enabled results in error. ([#53107](https://github.com/kubernetes/kubernetes/pull/53107), [@Random-Liu](https://github.com/Random-Liu))

    * With this feature, users can config kube-addon-manager to whitelist those resources to fix this issue.

- Optimized calculating stats when only CPU and Memory stats are returned from Kubelet stats/summary http endpoint.  ([#68841](https://github.com/kubernetes/kubernetes/pull/68841), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
