* Adds a new `kubeadm config` command that lets users tell `kubeadm upgrade` what kubeadm configuration to use and lets users view the current state. ([#50980](https://github.com/kubernetes/kubernetes/pull/50980), [@luxas](https://github.com/luxas))

The extra functions here are stubs to satisfy the references in the C
code generated for gcc. The build process links this stub, along with
_cgo_export.c and *.cgo2.c, into a dynamic executable and then lets
cgo examine the executable. Cgo records the list of shared library
references and resolved names and writes them into a new file
_cgo_import.go, which looks like:

	//go:cgo_dynamic_linker "/lib64/ld-linux-x86-64.so.2"

    val response2 = responses.take()
    assertThat(response2).isEqualTo("DEF")
    assertThat(server.takeRequest().exchangeIndex).isEqualTo(1)
    assertThat(server.takeRequest().exchangeIndex).isEqualTo(0)

    // Let the first request proceed. It should discard the the held HTTP/2 connection and get a new
    // one.
    latch.countDown()
    val response3 = responses.take()
    assertThat(response3).isEqualTo("ABC")

* Add kubelet --network-plugin-mtu flag for MTU selection ([#30376](https://github.com/kubernetes/kubernetes/pull/30376), [@justinsb](https://github.com/justinsb))
* Let Services preserve client IPs and not double-hop from external LBs (alpha) ([#29409](https://github.com/kubernetes/kubernetes/pull/29409), [@girishkalele](https://github.com/girishkalele))

- TaintNodeByCondition has been moved to Beta and is enabled by default.
- Scheduler throughput has been improved by ~50% in large clusters (>2000 nodes).

### SIG-service-catalog
- The Originating Identity feature, which lets the broker know which user that performed an action, is now GA.

- Added alpha support for field selectors on custom resources.
  Provided that the `CustomResourceFieldSelectors` feature gate is enabled, the CustomResourceDefinition
  API now lets you specify `selectableFields`. Listing a field there allows filtering custom resources for that
