asserts that <code>x</code> is not <code>nil</code>

More precisely, if <code>T</code> is not an interface type, <code>x.(T)</code> asserts
that the dynamic type of <code>x</code> is <a href="#Type_identity">identical</a>

- OIDC authentication will now fail if the username asserted based on a CEL expression config is the empty string.  Previously the request would be authenticated with the username set to the empty string. ([#123568](https://github.com/kubernetes/kubernetes/pull/123568), [@enj](https://github.com/enj))

- The `apiserver_request_total` metric is promoted to stable status and no longer has a content-type dimensions, so any alerts/charts which presume the existence of this will fail. This is however, unlikely to be the case since it was effectively an unbounded dimension in the first place. ([#99788](https://github.com/kubernetes/kubernetes/pull/99788), [@logicalhan](https...

### SIG API Machinery

[SIG API Machinery][] is responsible for all aspects of the API server: API registration and discovery, generic API CRUD semantics, admission control, encoding/decoding, conversion, defaulting, persistence layer (etcd), OpenAPI, third-party resources, garbage collection, and client libraries.

### Contextual Logging in Alpha

Kubernetes 1.24 has introduced [contextual logging](https://github.com/kubernetes/enhancements/issues/3077)
that enables the caller of a function to control all aspects of logging (output formatting, verbosity, additional values and names).

### Avoiding Collisions in IP allocation to Services

Kubernetes 1.24 introduced a new opt-in feature that allows you to
