def get_invalid_none():
    if flag:
        return {"name": "foo"}
    # if flag is False, at this point the function will implicitly return None
```

If you have *path operations* using `response_model` that need to be allowed to return `None`, make it explicit in `response_model` using `Union[Something, None]`:

```Python
from typing import Union

from fastapi import FastAPI

	// destination are same objects. Apply this restriction also when
	// metadataOnly is true indicating that we are not overwriting the object.
	// if encryption is enabled we do not need explicit "REPLACE" metadata to
	// be enabled as well - this is to allow for key-rotation.
	if !isDirectiveReplace(r.Header.Get(xhttp.AmzMetadataDirective)) && !isDirectiveReplace(r.Header.Get(xhttp.AmzTagDirective)) &&

  - The deprecated versionless API group accessors (like `clientset.Apps()`) have been removed. Use an explicit version instead (like `clientset.AppsV1()`) ([#74422](https://github.com/kubernetes/kubernetes/pull/74422), [@liggitt](https://github.com/liggitt))

- Added new -f flag into debug command to be used passing pod or node files instead explicit names. ([#111453](https://github.com/kubernetes/kubernetes/pull/111453), [@ardaguclu](https://github.com/ardaguclu))

- The command line flag `enable-taint-manager` for kube-controller-manager is deprecated and will be removed in 1.26. The feature that it supports, taint based eviction, is enabled by default and will continue to be implicitly enabled when the flag is removed.

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

#### kube-apiserver:
- in an `--encryption-provider-config` config file, an explicit `cacheSize: 0` parameter previously silently defaulted to caching 1000 keys. In Kubernetes 1.18, this now returns a config validation error. To disable caching, you can specify a negative cacheSize value in Kubernetes 1.18+.

* Restored old behavior to the `--template` flag in `get.go`. In old releases, providing a `--template` flag value and no `--output` value implicitly assigned a default value ("go-template") to `--output`, printing using the provided template argument.
([#65377](https://github.com/kubernetes/kubernetes/pull/65377),[@juanvallejo](https://github.com/juanvallejo))

* bump(golang.org/x/oauth2): a6bd8cefa1811bd24b86f8902872e4e8225f74c4 ([#45056](https://github.com/kubernetes/kubernetes/pull/45056), [@ericchiang](https://github.com/ericchiang))
* apimachinery: make explicit that meta.KindToResource is only a guess ([#45272](https://github.com/kubernetes/kubernetes/pull/45272), [@sttts](https://github.com/sttts))
