- Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. ([#88911](https://github.com/kubernetes/kubernetes/pull/88911), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]

    - `scheduler_async_api_call_execution_total`: tracks executed API calls by call type and result (success/error)
    - `scheduler_async_api_call_duration_seconds`: histogram of API call execution duration by call type and result

*_admission_latencies_milliseconds_summary and *_admission_latencies_milliseconds metrics because they were reporting seconds rather than milliseconds. They were also subject to multiple naming guideline violations (units should be in base units and "duration" is the best practice labelling to measure the time a request takes). Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary, as these now report the unit as described, and follow the instrumentation best practices....

- The new feature gate "SidecarContainers" is now available. This feature introduces sidecar containers, a new type of init container that starts before other containers but remains running for the full duration of the pod's lifecycle and will not block pod termination. ([#116429](https://github.com/kubernetes/kubernetes/pull/116429), [@gjkim42](https://github.com/gjkim42)) [SIG API Machinery, Apps, Node, Scheduling and Testing]

- A new sleep action for the `PreStop` lifecycle hook was added, allowing containers to pause for a specified duration before termination. ([#119026](https://github.com/kubernetes/kubernetes/pull/119026), [@AxeZhan](https://github.com/AxeZhan))

- The `WaitFor` and `WaitForWithContext` functions in the wait package have now been marked private. Callers should use the equivalent `Poll*` method with a zero duration interval.

  `You did,' said the Mock Turtle.

  `Hold your tongue!' added the Gryphon, before Alice could speak
again.  The Mock Turtle went on.

  `We had the best of educations--in fact, we went to school
every day--'

  `I'VE been to a day-school, too,' said Alice; `you needn't be
so proud as all that.'

  `With extras?' asked the Mock Turtle a little anxiously.

* PodSecurityPolicy admission information has been added to audit logs. ([#58143](https://github.com/kubernetes/kubernetes/pull/58143), [@CaoShuFeng](https://github.com/CaoShuFeng))
