## Changelog since v1.20.11

## Changes by Kind

### API Change

- Kube-apiserver: Fixes handling of CRD schemas containing literal null values in enums (#104990, @liggitt) [SIG API Machinery, Apps and Network]

### Bug or Regression

Definicja schematu zawiera ścieżki API, możliwe parametry, które są przyjmowane przez endpointy, itp.

#### "Schemat" danych

Termin "schemat" może również odnosić się do wyglądu niektórych danych, takich jak zawartość JSON.

W takim przypadku będzie to oznaczać atrybuty JSON, ich typy danych itp.

#### OpenAPI i JSON Schema

- Fixed nil pointer error in `NodeVolumeLimits` csi logging ([#115179](https://github.com/kubernetes/kubernetes/pull/115179), [@sunnylovestiramisu](https://github.com/sunnylovestiramisu))
- Fixed panic validating custom resource definition schemas that set `multipleOf` to 0 ([#114869](https://github.com/kubernetes/kubernetes/pull/114869), [@liggitt](https://github.com/liggitt))

* Eviction thresholds set to 0% or 100% will turn off eviction. ([#59681](https://github.com/kubernetes/kubernetes/pull/59681), [@mtaufen](https://github.com/mtaufen))

* CustomResourceDefinitions: OpenAPI v3 validation schemas containing `$ref`references are no longer permitted. Before upgrading, ensure CRD definitions do not include those `$ref` fields. ([#58438](https://github.com/kubernetes/kubernetes/pull/58438), [@carlory](https://github.com/carlory))

        * In responses, the `set` will be converted to a `list`.
        * The generated schema will specify that the `set` values are unique (using JSON Schema's `uniqueItems`).
* `bytes`:
    * Standard Python `bytes`.
    * In requests and responses will be treated as `str`.
    * The generated schema will specify that it's a `str` with `binary` "format".
* `Decimal`:
    * Standard Python `Decimal`.

- Added support for CEL(Common Expression Language) expressions and `additionalProperties` to be used under nested quantifiers in CRD schemas. ([#124381](https://github.com/kubernetes/kubernetes/pull/124381), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]
- Added support for building Windows kube-proxy container image.

			cacheStore.Store(embeddedCacheKey, true)
			if field.EmbeddedSchema, err = getOrParse(fieldValue.Interface(), cacheStore, embeddedNamer{Table: schema.Table, Namer: schema.namer}); err != nil {
				schema.err = err
			}

			for _, ef := range field.EmbeddedSchema.Fields {
				ef.Schema = schema
				ef.OwnerSchema = field.EmbeddedSchema
				ef.BindNames = append([]string{fieldStruct.Name}, ef.BindNames...)

이 모든 것은 개발자들에게 최고의 개발 경험을 제공하기 위해 설계되었습니다.

## 필요조건

여러 대안을 테스트한 후, [Pydantic](https://docs.pydantic.dev/)을 사용하기로 결정했습니다.

이후 저는 **Pydantic**이 JSON Schema와 완벽히 호환되도록 개선하고, 다양한 제약 조건 선언을 지원하며, 여러 편집기에서의 자동 완성과 타입 검사 기능을 향상하기 위해 기여했습니다.

또한, 또 다른 주요 필요조건이었던 [Starlette](https://www.starlette.io/)에도 기여했습니다.

## 개발

That's because it is using the same name as in the OpenAPI spec. So that if you need to investigate more about any of these security schemes you can just copy and paste it to find more information about it.

///

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".

It could be called as:
