Action required for custom scheduler plugin developers:
  Plugins **have to** implement a QueueingHint for Pod/Update event if the rejection from them could be resolved by updating unscheduled Pods themselves.
  Example: suppose you develop a custom plugin that denies Pods that have a `schedulable=false` label. 

- Alpha support for field selectors on custom resources has been added. With the `CustomResourceFieldSelectors` feature gate enabled, the CustomResourceDefinition API now allows specifying `selectableFields`. Listing a field there enables filtering custom resources for that CustomResourceDefinition in list or watch requests. ([#122717](https://github.com/kubernetes/kubernetes/pull/122717), [@jp...

## Кастомная валидация { #custom-validation }

Бывают случаи, когда нужна **кастомная валидация**, которую нельзя выразить параметрами выше.

type BaseOptions struct{}

// RenameOptions represents rename API options, currently its same as BaseOptions
type RenameOptions struct {
	BaseOptions
}

// DiskInfoOptions options for requesting custom results.
type DiskInfoOptions struct {
	DiskID  string `msg:"id"`
	Metrics bool   `msg:"m"`
	NoOp    bool   `msg:"np"`
}

// DiskInfo is an extended type which returns current
// disk usage per path.

但如果你需要，它就在這裡。🤓

如果你想攔截例外並據此回傳自訂回應，請建立一個[自訂例外處理器](../handling-errors.md#install-custom-exception-handlers)。

## 含 `yield` 與 `except` 的相依 { #dependencies-with-yield-and-except }

如果你在含 `yield` 的相依中用 `except` 攔截了例外，且沒有再次拋出它（或拋出新的例外），FastAPI 將無法察覺有例外發生，就像在一般的 Python 中一樣：

## Кастомна валідація { #custom-validation }

Можуть бути випадки, коли вам потрібно провести кастомну валідацію, яку не можна реалізувати за допомогою параметрів, показаних вище.
