- `PodLifecycleSleepAction` is now turned on by default allowing users to create containers with sleep lifecycle action with a duration of zero seconds ([#130621](https://github.com/kubernetes/kubernetes/pull/130621), [@sreeram-venkitesh](https://github.com/sreeram-venkitesh)) [SIG Node]

    - `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

- 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))

- Added a one-time random duration of up to 50% of kubelet's `nodeStatusReportFrequency` to help spread the node status update load evenly over time. ([#128640](https://github.com/kubernetes/kubernetes/pull/128640), [@mengqiy](https://github.com/mengqiy))

  `You did,' said the Mock Turtle.

  `Hold your tongue!' added the Gryphon, before Alice could speak

  `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.

- Watch requests that are delegated to aggregated API servers no longer reserve concurrency units (seats) in the API Priority and Fairness dispatcher for their entire duration. ([#105511](https://github.com/kubernetes/kubernetes/pull/105511), [@benluddy](https://github.com/benluddy))

- Kubelet: add `kubelet_volume_metric_collection_duration_seconds` metrics for volume disk usage calculation duration ([#107201](https://github.com/kubernetes/kubernetes/pull/107201), [@pacoxu](https://github.com/pacoxu))
