- Added support for kube-proxy iptables mode to track packets that were wrongfully marked invalid by conntrack and subsequently dropped by introducing `kubeproxy_iptables_ct_state_invalid_dropped_packets_total` metric. ([#122812](https://github.com/kubernetes/kubernetes/pull/122812), [@aroradaman](https://g...

- Updated apiserver metric `request_filter_duration_seconds` to include a 10s, 15s and 30s bucket.
Updated apiserver metric `request_wait_duration_seconds` to include a 15s bucket. ([#118945](https://github.com/kubernetes/kubernetes/pull/118945), [@andrewsykim](https://github.com/andrewsykim))

<p>
A <i>block</i> is a possibly empty sequence of declarations and statements
within matching brace brackets.

In addition to explicit blocks in the source code, there are implicit blocks:

                to the location where the OpenAPI document is being served. Variable
                substitutions will be made when a variable is named in `{`brackets`}`.
                * `description`: An optional string describing the host designated by
                the URL. [CommonMark syntax](https://commonmark.org/) MAY be used for
                rich text representation.

- 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. ([#121719](https://github.com/kubernetes/kubernetes/pull/121719), [@ruiwen-zhao](https://github.com/ruiwen-zhao))

- 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))
