- When the `PodObservedGenerationTracking` feature gate was set, the kubelet populated `status.observedGeneration` to reflect the latest `metadata.generation` it observed for the pod.

 *  New: Support request bodies on HTTP/1.1 connection upgrades.
 *  New: `EventListener.plus()` makes it easier to observe events in multiple listeners.
 *  Fix: Don't spam logs with _‘Method isLoggable in android.util.Log not mocked.’_ when using
    OkHttp in Robolectric and Paparazzi tests.
 *  Upgrade: [Kotlin 2.2.21][kotlin_2_2_21].

- Introduced compressible resource setting on system reserved and kube reserved slices. ([#125982](https://github.com/kubernetes/kubernetes/pull/125982), [@harche](https://github.com/harche))

- Kube-apiserver: Fixed a possible `v1.34` performance regression calculating object size statistics for resources not served from the watch cache, typically only `Events`. ([#133873](https://github.com/kubernetes/kubernetes/pull/133873), [@serathius](https://github.com/serathius)) [SIG API Machinery and Etcd]

  - Added user-owned fields in `ResourceClaim` to specify resource requirements against each device capacity.
  - Added scheduler-owned field in `ResourceClaim.Status` to specify how much device capacity is reserved for a specific request.
  - Added an additional identifier to `ResourceClaim.Status` for the device supports multiple allocations.
