It is likely that `v1alpha2` will be removed in one of the future Kubernetes releases to be able to develop `v1`.

### 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.

   ([#123384](https://github.com/kubernetes/kubernetes/pull/123384), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska))
- In kubeadm, in the new output API 'output.kubeadm.k8s.io/v1alpha3', the UpgradePlan structure that is used when calling 'kubeadm upgrade plan ... -o yaml|json' was modified to include a list of multiple available upgrades.

### Structured logging

SIG Instrumentation standardized the structure of log messages and references to Kubernetes objects. Structured logging makes parsing, processing, storing, querying and analyzing logs easier. New methods in the klog library enforce log message structure.

### EndpointSlices are now enabled by default

but are otherwise ignored.

<pre>
struct {
	x, y float64 ""  // an empty tag string is like an absent tag
	name string  "any string is permitted as a tag"
	_    [4]byte "ceci n'est pas un champ de structure"
}

// A struct corresponding to a TimeStamp protocol buffer.
// The tag strings define the protocol buffer field numbers;
// they follow the convention outlined by the reflect package.

### Structured Logging in Kubelet

* ♻️ Refactor and simplify internal `analyze_param()` to structure data with dataclasses instead of tuple. PR [#12099](https://github.com/fastapi/fastapi/pull/12099) by [@tiangolo](https://github.com/tiangolo).
* ♻️ Refactor and simplify dependencies data structures with dataclasses. PR [#12098](https://github.com/fastapi/fastapi/pull/12098) by [@tiangolo](https://github.com/tiangolo).

### Docs

- Migrate `volume/csi/csi-client.go` logs to structured logging. ([#99441](https://github.com/kubernetes/kubernetes/pull/99441), [@CKchen0726](https://github.com/CKchen0726))
- Migrate statefulset files to structured logging ([#106109](https://github.com/kubernetes/kubernetes/pull/106109), [@h4ghhh](https://github.com/h4ghhh))

## **Action Required Before Upgrading**

### Network

- Fixed code-generator client-gen to work with `api/v1`-like package structure. ([#125162](https://github.com/kubernetes/kubernetes/pull/125162), [@sttts](https://github.com/sttts)) [SIG API Machinery and Apps]
