- Existing PVs are converted to use volume topology if migration is enabled. ([#83394](https://github.com/kubernetes/kubernetes/pull/83394), [@bertinatto](https://github.com/bertinatto))

   * awkward. This method lets you get a plain-old-{@code Map} out of a {@code Properties}.

   * @param properties a {@code Properties} object to be converted
   * @return an immutable map containing all the entries in {@code properties}
   * @throws ClassCastException if any key in {@code properties} is not a {@code String}

  - `priority_level_seat_count_watermarks` is removed.
  - `priority_level_request_count_samples` is replaced with `priority_level_request_utilization`, which samples every nanosecond rather than every millisecond; the old metric conveyed utilization despite its name.
  - `priority_level_request_count_watermarks` is removed.

* DaemonSet’s spec.templateGeneration has been deprecated.  ([#45924](https://github.com/kubernetes/kubernetes/pull/45924), [@janetkuo](https://github.com/janetkuo))

### Structured logging graduate to Beta

Structured logging reached its Beta milestone. Most log messages from kubelet and kube-scheduler have been converted. Users are encouraged to try out JSON output or parsing of the structured text format and provide feedback on possible solutions for the open issues, such as handling of multi-line strings in log values.

- The systemd config files are now reloaded before kubelet starts, so changes can take effect([#65702](https://github.com/kubernetes/kubernetes/pull/65702), [@mborsz](https://github.com/mborsz))
- Hostnames are now converted to lowercase before being used for node lookups in the kubernetes-worker charm. ([#65487](https://github.com/kubernetes/kubernetes/pull/65487), [@dshcherb](https://github.com/dshcherb))

* Fixes panic if a kubelet is run against an older kube-apiserver ([#74529](https://github.com/kubernetes/kubernetes/pull/74529), [@liggitt](https://github.com/liggitt))
* The resource group name in Azure providerID is not converted to lower cases. ([#74882](https://github.com/kubernetes/kubernetes/pull/74882), [@feiskyer](https://github.com/feiskyer))

### Feature

- 'Added selector validation to `HorizontalPodAutoscaler`: when multiple HPAs
  select the same set of Pods, scaling now will be disabled for those HPAs with
  the reason `AmbiguousSelector`. This change also covers a case when multiple HPAs
  point to the same deployment.'

### Bug or Regression

- A PV set from in-tree source will have ordered requirement values in NodeAffinity when converted to CSIPersistentVolumeSource ([#88987](https://github.com/kubernetes/kubernetes/pull/88987), [@jiahuif](https://github.com/jiahuif)) [SIG Storage]
