- Kubeadm: remove the deprecated flag `--insecure-port` from the kube-apiserver manifest that kubeadm manages. The flag had no effect since 1.20, since the insecure serving of the component was disabled in the same version. ([#102121](https://github.com/kubernetes/kubernetes/pull/102121), [@pacoxu](https://github.com/pacoxu))

 *  Breaking: Decompose the `RecordedRequest.requestLine` into three properties, `method`, `target`,
    and `version`. This better suits HTTP/2 where the request line had to be synthesized from
    component headers.

 *  Breaking: Change `RecordedRequest.body` from a mutable `Buffer` to an immutable `ByteString`.

 *  Breaking: Adopt Okio's new `Socket` interface for `MockResponse.socketHandler`.

// objects are slightly larger due to encryption overhead.

- Component-base/logs: when compiled with Go >= 1.21, component-base will automatically configure the slog default logger together with initializing klog. ([#120696](https://github.com/kubernetes/kubernetes/pull/120696), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture,...

either no local stack frame or no function calls,
the only requirement is to define a Go prototype for the function
in a Go source file in the same package. The name of the assembly
function must not contain the package name component (for example,
function <code>Syscall</code> in package <code>syscall</code> should
use the name <code>·Syscall</code> instead of the equivalent name
<code>syscall·Syscall</code> in its <code>TEXT</code> directive).
