- Fix panic in JSON logging format caused by missing Duration encoder ([#101158](https://github.com/kubernetes/kubernetes/pull/101158), [@serathius](https://github.com/serathius)) [SIG API Machinery, Cluster Lifecycle and Instrumentation]

*_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. ([#115116](https://github.com/kubernetes/kubernetes/pull/115116), [@smarterclayton](https://github.com/smarterclayton))

- 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))

* PodSecurityPolicy admission information has been added to audit logs. ([#58143](https://github.com/kubernetes/kubernetes/pull/58143), [@CaoShuFeng](https://github.com/CaoShuFeng))
* TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. ([#63999](https://github.com/kubernetes/kubernetes/pull/63999), [@mikedanese](https://github.com/mikedanese))

- 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))
