When cross-compiling, you must specify a C cross-compiler for cgo to
use. You can do this by setting the generic CC_FOR_TARGET or the
more specific CC_FOR_${GOOS}_${GOARCH} (for example, CC_FOR_linux_arm)
environment variable when building the toolchain using make.bash,
or you can set the CC environment variable any time you run the go tool.

- Append the image pull error for the pods `status.containerStatuses[*].state.waiting.message` when
  in image pull back-off (`reason` is `ImagePullBackOff`) instead of the generic `Back-off pulling image…` message. ([#127918](https://github.com/kubernetes/kubernetes/pull/127918), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node and Testing]

    * The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.
* The apiserver, including both the kube-apiserver and apiservers built with the generic apiserver library, will now return 413 RequestEntityTooLarge error if a json patch contains more than 10,000 operations.

- Clients may now request that API objects are converted to the `v1.Table` and `v1.PartialObjectMetadata` forms for generic access to objects. ([#77448](https://github.com/kubernetes/kubernetes/pull/77448), [@smarterclayton](https://github.com/smarterclayton))
