- 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.

- Azure File CSI migration is now GA. ([#113160](https://github.com/kubernetes/kubernetes/pull/113160), [@andyzhangx](https://github.com/andyzhangx))
- Changed `preemption_victims` metric bucket from `LinearBuckets` to `ExponentialBuckets`. ([#112939](https://github.com/kubernetes/kubernetes/pull/112939), [@lengrongfu](https://github.com/lengrongfu))

  - false/ignore - perform no validation, silently dropping invalid fields from the object. ([#108350](https://github.com/kubernetes/kubernetes/pull/108350), [@kevindelgado](https://github.com/kevindelgado))

* Third Party Resource tests in the e2e suite were incorrectly marked as part of the conformance bucket.  They are alpha and are not required for conformance. ([#52823](https://github.com/kubernetes/kubernetes/pull/52823), [@smarterclayton](https://github.com/smarterclayton))

* Kubernetes version command line parameter in kubeadm has been updated to drop an unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest...

- Kubelet metrics have been changed to buckets. 
  For example the exec/{podNamespace}/{podID}/{containerName} is now just exec. ([#87913](https://github.com/kubernetes/kubernetes/pull/87913), [@cheftako](https://github.com/cheftako)) [SIG Node]
