- Expose `rest_client_rate_limiter_duration_seconds` metric to component-base to track client side rate limiter latency in seconds. Broken down by verb and URL.

- `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]

- DRA: The scheduler plugin prevented abnormal filter runtimes by timing out after 10 seconds. This was configurable via the plugin configuration's `FilterTimeout`. Setting it to zero disabled the timeout and restored the behavior of Kubernetes <= 1.33. ([#132033](https://github.com/kubernetes/kubernetes/pull/132033), [@pohly](https://github.com/pohly))...

### Bug or Regression

- Fix Topology Aware Hints not working when the `topology.kubernetes.io/zone` label is added after Node creation
  - Fix a data race in TopologyCache when `AddHints` and `SetNodes` are called concurrently ([#117269](https://github.com/kubernetes/kubernetes/pull/117269), [@tnqn](https://github.com/tnqn)) [SIG Apps and Network]

* GCE/GKE load balancer health check default interval changes from 2 seconds to 8 seconds, unhealthyThreshold to 3. ([#70099](https://github.com/kubernetes/kubernetes/pull/70099), [@grayluck](https://github.com/grayluck))
    * Health check parameters are configurable to be bigger than default values.

* CSI detach timeout increased from 10 seconds to 2 minutes ([#84321](https://github.com/kubernetes/kubernetes/pull/84321), [@cduchesne](https://github.com/cduchesne))

- Kubelets configured to rotate client certificates now publish a `certificate_manager_server_ttl_seconds` gauge metric indicating the remaining seconds until certificate expiration. ([#91148](https://github.com/kubernetes/kubernetes/pull/91148), [@liggitt](https://github.com/liggitt)) [SIG Auth and Node]

- A new kubelet metric `image_pull_duration_seconds` was added. The metric tracks the duration (in seconds) it takes for an image to be pulled, including the time spent in the waiting queue of image puller. The metric is broken down by bucketed image size.
