*  Fix: Prefer the server's response body on all conditional cache misses. Previously we would
    return the cached response's body if it had a newer `Last-Modified` date.
 *  Fix: Update the stored timestamp on conditional cache hits.
 *  New: Optimized HTTP/2 request header encoding. More headers are HPACK-encoded and string
    literals are now Huffman-encoded.
 *  New: Expose `Part` headers and body in `Multipart`.

* Handle federated service name lookups in kube-dns. ([#25727](https://github.com/kubernetes/kubernetes/pull/25727), [@madhusudancs](https://github.com/madhusudancs))
* Support sort-by timestamp in kubectl get ([#25600](https://github.com/kubernetes/kubernetes/pull/25600), [@janetkuo](https://github.com/janetkuo))

* Upgrade Stackdriver Logging Agent addon image to 0.6-1.6.0-1 to use Fluentd v1.2. This provides nanoseconds timestamp granularity for logs. ([#70954](https://github.com/kubernetes/kubernetes/pull/70954), [@qingling128](https://github.com/qingling128))

  `terminating` is true when an endpoint is terminating. For pods this is any endpoint with a deletion timestamp. ([#92968](https://github.com/kubernetes/kubernetes/pull/92968), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Add dual-stack Services (alpha).  This is a BREAKING CHANGE to an alpha API.

- Fixed bug that kubelet resource metric `container_start_time_seconds` had timestamp equal to container start time. ([#120518](https://github.com/kubernetes/kubernetes/pull/120518), [@saschagrunert](https://github.com/saschagrunert)) [SIG Instrumentation, Node and Testing]

- Annotation `batch.kubernetes.io/cronjob-scheduled-timestamp` added to Job objects scheduled from CronJobs is promoted to stable. ([#128336](https://github.com/kubernetes/kubernetes/pull/128336), [@soltysh](https://github.com/soltysh))

  * Fix a bug where container cannot run as root when SecurityContext.RunAsNonRoot is false. ([#47009](https://github.com/kubernetes/kubernetes/pull/47009), [@yujuhong](https://github.com/yujuhong))

  * Fix the Kubelet PLEG update timestamp to better reflect the health of the component when the container runtime request hangs. ([#45496](https://github.com/kubernetes/kubernetes/pull/45496), [@andyxning](https://github.com/andyxning))

- Fixed the bug where Events failed to be created when the referenced object name was not a valid Event name. Now, a UUID is used as the name instead of the referenced object name and the timestamp suffix. ([#129790](https://github.com/kubernetes/kubernetes/pull/129790), [@aojea](https://github.com/aojea))
