Pull requests
-------------

Unless the change is a trivial fix such as for a typo, it's generally best to
start by opening a new issue describing the bug or feature you're intending to
fix. Even if you think it's relatively minor, it's helpful to know what people
are working on. And as mentioned above, API changes should be discussed
thoroughly before moving to code.

- New flag `--show-hidden-metrics-for-version` in kube-proxy, kubelet, kube-controller-manager, and kube-scheduler can be used to show all hidden metrics that are deprecated in the previous minor release. ([#85279](https://github.com/kubernetes/kubernetes/pull/85279), [@RainbowMango](https://github.com/RainbowMango)) [SIG Cluster Lifecycle and Network]

#### Features graduated to beta:

- The RuntimeClass scheduler can now simplify steering Linux or Windows pods to appropriate nodes
- All Windows nodes now get the new label `node.kubernetes.io/windows-build` that reflects the Windows major, minor, and build number that are needed to match compatibility between Windows containers and Windows worker nodes.


## Deprecations and Removals

* kubectl: This client version requires the `apps/v1` APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away. ([#61419](https://github.com/kubernetes/kubernetes/pull/61419), [@enisoc](https://github.com/enisoc))

- Adds `create ingress` command to `kubectl` ([#78153](https://github.com/kubernetes/kubernetes/pull/78153), [@amimof](https://github.com/amimof)) [SIG CLI and Network]
- Adds a headless service on node-local-cache addon. ([#88412](https://github.com/kubernetes/kubernetes/pull/88412), [@stafot](https://github.com/stafot)) [SIG Cloud Provider and Network]

- Kubectl version changed to write a warning message to stderr if the client and server version difference exceeds the supported version skew of +/-1 minor version. ([#98250](https://github.com/kubernetes/kubernetes/pull/98250), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]
