- 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

- Fix: Bug in `kube-proxy` latency metrics to calculate only the latency value for the `Endpoints` that are created after it starts running. This is needed because all the `Endpoints` objects are processed on restarts, independently when they were. ([#100861](https://github.com/kubernetes/kubernetes/pull/100861), [@aojea](https://github.com/aojea))

- Promote StatefulSet minReadySeconds to GA. This means `--feature-gates=StatefulSetMinReadySeconds=true` are not needed on kube-apiserver and kube-controller-manager binaries and they'll be removed soon following policy at https://kubernetes.io/docs/reference/using-api/deprecation-policy/#deprecation ([#110896](https://github.com/kubernetes/kubernetes/pull/110896),...

* Include CRD for BGPConfigurations, needed for calico 2.x to 3.x upgrade. ([#71868](https://github.com/kubernetes/kubernetes/pull/71868), [@satyasm](https://github.com/satyasm))

- HTTP/2 connection health check is enabled by default in all Kubernetes clients to fix persistently broken connections (https://github.com/kubernetes/client-go/issues/374). If needed, users can tune the feature via the HTTP2_READ_IDLE_TIMEOUT_SECONDS and HTTP2_PING_TIMEOUT_SECONDS environment variables. The feature is disabled if HTTP2_READ_IDLE_TIMEOUT_SECONDS is set to 0. ([#100376](https://github.com/kubernetes/kubernetes/pull/100376),...

                # By placing the middleware and the AsyncExitStack here, inside all
                # user middlewares, the same context is used.
                # This is currently not needed, only for closing files, but used to be
                # important when dependencies with yield were closed here.
                Middleware(AsyncExitStackMiddleware),  # ty: ignore[invalid-argument-type]

- When invoked with `-list-images`, the `e2e.test` binary now also lists the images that might be needed for storage tests. ([#108458](https://github.com/kubernetes/kubernetes/pull/108458), [@pohly](https://github.com/pohly))

### **CLI**

*   Swagger 1.2 validation is removed for kubectl. The options `--use-openapi` and `--schema-cache-dir` are also removed because they are no longer needed. ([#53232](https://github.com/kubernetes/kubernetes/pull/53232),[ @apelisse](https://github.com/apelisse))
