<p>
An array is a numbered sequence of elements of a single
type, called the element type.
The number of elements is called the length of the array and is never negative.

### 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 ([#117268](https://github.com/kubernetes/kubernetes/pull/117268), [@tnqn](https://github.com/tnqn)) [SIG Apps and Network]

### 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]

- Added multiplication functionality to `Quantity`. ([#117411](https://github.com/kubernetes/kubernetes/pull/117411), [@tenzen-y](https://github.com/tenzen-y))
- Added new feature gate called `RuntimeClassInImageCriApi` to address `kubelet` changes needed for KEP 4216.
  Noteable changes:
  1. Populate new `RuntimeHandler` field in CRI's `ImageSpec` struct during image pulls from container runtimes.

#### Cluster Discovery/Bootstrap

* [beta] The authentication and verification mechanism called Bootstrap Tokens is improved. Use Bootstrap Tokens to easily add new node identities to a cluster. ([#130](https://github.com/kubernetes/enhancements/issues/130), [@luxas](https://github.com/luxas), [@jbeda](https://github.com/jbeda)).

    * If you depended on that previous behavior, you might need to update your code. As always, make sure your tests pass before merging the upgrade.
