- Kube-controller-manager: the dynamic resource controller steps in when a pod got created such that the scheduler ignores it (i.e. spec.nodeName is set) and then takes care of triggering delayed resource claim allocation and/or reserving a claim for the pod. ([#118209](https://github.com/kubernetes/kubernetes/pull/118209),...

performing the TLS Bootstrap properly. Earlier, `kubeadm join` only did the discovery part and exited successfully without checking that the kubelet actually started properly and performed the TLS bootstrap correctly. Now, as kubeadm runs some post-join steps (for example, annotating the Node API object with the CRISocket), `kubeadm join` is now waiting for the kubelet to perform the TLS Bootstrap, and then uses that credential to perform further actions. This also improves the UX, as `kubeadm` will exit...

- A new sleep action for the `PreStop` lifecycle hook was added, allowing containers to pause for a specified duration before termination. ([#119026](https://github.com/kubernetes/kubernetes/pull/119026), [@AxeZhan](https://github.com/AxeZhan))

- If a pod has a running instance, the stats of its previously terminated instances will not show up in the kubelet summary stats any more for CRI runtimes such as containerd and cri-o. This keeps the behavior consistent with Docker integration, and fixes an issue that some container Prometheus metrics don't work when there are summary stats for multiple instances of the same pod. ([#77426](https://github.com/kubernetes/kubernetes/pull/77426),...

- Fixes a bug that when there is a "connection refused" error, the reflector's ListAndWatch func will return directly but what expected is that sleep 1 second and rewatch since the specified resourceVersion.

In v1.9 SIG AWS has improved stability of 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.
