- Kube-proxy: delete stale conntrack UDP entries for loadbalancer ingress IP. ([#104151](https://github.com/kubernetes/kubernetes/pull/104151), [@aojea](https://github.com/aojea)) [SIG Network]
- Metrics changes: Fix exposed buckets of `scheduler_volume_scheduling_duration_seconds_bucket` metric ([#100720](https://github.com/kubernetes/kubernetes/pull/100720), [@dntosas](https://github.com/dntosas)) [SIG Apps, Instrumentation, Scheduling and Storage]

- Metric buckets for `pod_start_duration_seconds` were changed to `{0.5, 1, 2, 3, 4, 5, 6, 8, 10, 20, 30, 45, 60, 120, 180, 240, 300, 360, 480, 600, 900, 1200, 1800, 2700, 3600}`. ([#120680](https://github.com/kubernetes/kubernetes/pull/120680), [@ruiwen-zhao](ht...

    * - Don't generate empty record for externalName service.
    * - Add validation for upstreamNameserver port.
    * - Update go version to 1.9.3.
* Fix mounting of UNIX sockets(and other special files) in subpaths ([#61480](https://github.com/kubernetes/kubernetes/pull/61480), [@gnufied](https://github.com/gnufied))

- Kubelet metrics have been changed to buckets. 
  For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]

### Feature

- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ...

*   TensorBoard disables all runs by default if there are more than 40 runs.
*   Removed old doc generator code.
*   GCS file system integration now supports domain buckets, e.g
    gs://bucket.domain.com/path.
*   Add `tf.summary.text` for outputting text to TensorBoard.
*   The "run" command of tfdbg's command-line interface now supports filtering
