 *  **OkHttp has an experimental new API for tracking metrics.** The new
    `EventListener` API is designed to help developers monitor HTTP requests'
    size and duration. This feature is an unstable preview: the API is subject

  Jobs that are tracked using this mechanism get the annotation `batch.kubernetes.io/job-tracking`. This is a temporary measure. Two releases after this feature graduates to beta, the annotation won't be added to Jobs anymore. ([#98817](https://github.com/kubernetes/kubernetes/pull/98817), ...

with lower latency than before (2s vs 4s, on average) and rapid updates to pod configuration should take effect sooner.
  
  A new metric `kubelet_known_pods` has been added at ALPHA stability to report the number of pods a Kubelet is tracking in a number of internal states.  Operators may use the metrics to track an excess of pods in the orphaned state that may not be completing.

     * Read operations can thus proceed without locking, but rely on selected uses of volatiles to
     * ensure that completed write operations performed by other threads are noticed. For most
     * purposes, the "count" field, tracking the number of elements, serves as that volatile
     * variable ensuring visibility. This is convenient because this field needs to be read in many
     * read operations anyway:

// using a delete-marker and MetaSys entries. It's used to track tiered content of a

// This kind of tracking is necessary since a version's tiered content is deleted asynchronously.

- Added progress tracking for volume permission and ownership changes. ([#130398](https://github.com/kubernetes/kubernetes/pull/130398), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]

- Removed tracking annotation from validation and defaulting. ([#117633](https://github.com/kubernetes/kubernetes/pull/117633), [@kannon92](https://github.com/kannon92))

* The Prometheus metrics for the kube-apiserver for tracking incoming API requests and latencies now return the subresource label for correctly attributing the type of API call. ([#46354](https://github.com/kubernetes/kubernetes/pull/46354), [@smarterclayton](https://github.com/smarterclayton))
