- Make EBS volume expansion faster ([#66728](https://github.com/kubernetes/kubernetes/pull/66728), [@gnufied](https://github.com/gnufied))
- Remove unused binary and container image for kube-aggregator. The functionality is already integrated into the kube-apiserver. ([#67157](https://github.com/kubernetes/kubernetes/pull/67157), [@dims](https://github.com/dims))

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods.

many teeth, so she felt that it ought to be treated with respect.

  `Cheshire Puss,' she began, rather timidly, as she did not at
all know whether it would like the name:  however, it only
grinned a little wider.  `Come, it's pleased so far,' thought

- Slow container runtime initialization no longer causes the System WatchDog to kill the kubelet. The Device Manager was treated as unhealthy until it began listening on its port.

* Mirror pods must now indicate the nodeName they are bound to on creation. The mirror pod annotation is now treated as immutable and cannot be added to an existing pod, removed from a pod, or modified.
