- Added progress tracking for volume permission and ownership changes. ([#130398](https://github.com/kubernetes/kubernetes/pull/130398), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]

* Fixes spurious 0-length API responses. ([#72856](https://github.com/kubernetes/kubernetes/pull/72856), [@liggitt](https://github.com/liggitt))
* Do not detach volume if mount in progress ([#71145](https://github.com/kubernetes/kubernetes/pull/71145), [@gnufied](https://github.com/gnufied))

- Added `singleProcessOOMKill` flag to the kubelet configuration. Setting that to true enable single process OOM killing in cgroups v2. In this mode, if a single process is OOM killed within a container, the remaining processes will not be OOM killed. ([#126096](https://github.com/kubernetes/kubernetes/pull/126096), [@utam0k](https://github.com/utam0k)) [SIG API Machinery, Node, Testing and Windows]

* `tf.lite`
    * Added support for `stablehlo.scatter`.

* `tf.estimator`
    * The tf.estimator API removal is in progress and will be targeted for the 2.16 release.

## Keras

- StatefulSets should always count `.status.availableReplicas` at the correct time without a delay. This results in faster progress of StatefulSet rollout. ([#136097](https://github.com/kubernetes/kubernetes/pull/136097), [@atiratree](https://github.com/atiratree)) [SIG Apps]

### Other (Cleanup or Flake)

- NONE

- Sync node status during kubelet node shutdown.
  Adds an pod admission handler that rejects new pods when the node is in progress of shutting down. ([#98005](https://github.com/kubernetes/kubernetes/pull/98005), [@wzshiming](https://github.com/wzshiming)) [SIG Node]

- If using cgroups v2, then the cgroup aware OOM killer will be enabled for container cgroups via  `memory.oom.group` .  This causes processes within the cgroup to be treated as a unit and killed simultaneously in the event of an OOM kill on any process in the cgroup. ([#117793](https://github.com/kubernetes/kubernetes/pull/117793), [@tzneal](https://github.com/tzneal)) [SIG Apps, Node...

- The `e2e.test` binary no longer emits JSON structs to document progress. ([#113212](https://github.com/kubernetes/kubernetes/pull/113212), [@pohly](https://github.com/pohly))

SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:
- Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.

kube-scheduler and kube-controller manager now use SO_REUSEPORT socket option when listening on address defined by --bind-address and --secure-port flags, when running on Unix systems (Windows is NOT supported). This allows to run multiple instances of those processes on a single host with the same configuration, which allows to update/restart them in a graceful way, without causing downtime.
