- Kube-apiserver: resolved a regression that treated `304 Not Modified` responses from aggregated API servers as internal errors ([#112530](https://github.com/kubernetes/kubernetes/pull/112530), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

* Auto-generate a "server" in OpenAPI `servers` when there's a `root_path` instead of prefixing all the `paths`:
    * Add a new parameter for `FastAPI` classes: `root_path_in_servers` to disable the auto-generation of `servers`.
    * New docs about `root_path` and `servers` in [Additional Servers](https://fastapi.tiangolo.com/advanced/behind-a-proxy/#additional-servers).

### Deprecation

- API server's deprecated `--service-account-api-audiences` flag was removed.  Use `--api-audiences` instead. ([#108624](https://github.com/kubernetes/kubernetes/pull/108624), [@ialidzhikov](https://github.com/ialidzhikov))

- Scheduler now waits for handlers to finish syncing before the scheduling cycles start. ([#116729](https://github.com/kubernetes/kubernetes/pull/116729), [@AxeZhan](https://github.com/AxeZhan))
- Set metrics-server's metric-resolution to 15s. ([#117121](https://github.com/kubernetes/kubernetes/pull/117121), [@dgrisonnet](https://github.com/dgrisonnet)) [SIG Cloud Provider and Instrumentation]

- The `RemoteRequestHeaderUID` feature moves to beta and is now enabled by default. This makes the kube-apiserver propagate UIDs in the `X-Remote-Uid` header in requests to the aggregated API servers. The header is not honored by default for incoming requests, but that can be enabled by setting the `--requestheader-uid-headers` flag explicitly. ([#130560](https://github.com/kubernetes/kubernetes/pull/130560), [@stlaz](https://github.com/stlaz))...

- Kube-apiserver: Each unique set of etcd server overrides specified with `--etcd-servers-overrides` surfaced health checks named `etcd-override-<index>` and `etcd-override-readiness-<index>`. These checks were still excluded by the `?exclude=etcd` and `?exclude=etcd-readiness` directives. ([#129438](https://github.com/kubernetes/kube...
