### API Change

- Added `omitempty` and `opt` tag to the API `v1beta2` AdminAccess type in the `DeviceRequestAllocationResult` struct. ([#132338](https://github.com/kubernetes/kubernetes/pull/132338), [@PatrickLaabs](https://github.com/PatrickLaabs))

these http/2 attacks may choose to disable the kube-apiserver mitigation to avoid disrupting load balancer -> kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may opt to disable the kube-apiserver mitigation to prevent performance regressions for unauthenticated clients. Authenticated requests rely on the fix in golang.org/x/net `v0.17.0` alone. https://issue.k8s.io/121197 tracks further mitigation of http/2 attacks...

### Bug or Regression

- Respect annotation size limit for server-side apply updates to the client-side apply annotation. Also, fix opt-out of this behavior by setting the client-side apply annotation to the empty string.
