* Enable lazy inode table and journal initialization for ext3 and ext4 ([#38865](https://github.com/kubernetes/kubernetes/pull/38865), [@codablock](https://github.com/codablock))
* Kubelet will no longer set hairpin mode on every interface on the machine when an error occurs in setting up hairpin for a specific interface. ([#36990](https://github.com/kubernetes/kubernetes/pull/36990), [@bboreham](https://github.com/bboreham))

### Kubernetes Node system swap support

* Adds the Categories []string field to API resources, which represents the list of group aliases (e.g. "all") that every resource belongs to. ([#43338](https://github.com/kubernetes/kubernetes/pull/43338), [@fabianofranz](https://github.com/fabianofranz))

- Fix kubelet NodeLease potential performance issues. Kubelet now will try to update lease using cached one instead of get from API Server every time. ([#81174](https://github.com/kubernetes/kubernetes/pull/81174), [@answer1991](https://github.com/answer1991))

# Dependencies { #dependencies }

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection" { #what-is-dependency-injection }

    @Timeout(value = 1, unit = TimeUnit.SECONDS) // Very short timeout
    void testBroadcastTimeout() {
        // Configure for broadcast-only resolution with very short timeout
        when(mockConfig.getResolveOrder()).thenReturn(Arrays.asList(ResolverType.RESOLVER_BCAST));
        when(mockConfig.getNetbiosSoTimeout()).thenReturn(50); // Very short
        when(mockConfig.getNetbiosRetryCount()).thenReturn(1);

* new dhcp-domain parameter to be used for figuring out the hostname of a node ([#61890](https://github.com/kubernetes/kubernetes/pull/61890), [@dims](https://github.com/dims))
* Disable ipamperf integration tests as part of every PR verification. ([#61863](https://github.com/kubernetes/kubernetes/pull/61863), [@satyasm](https://github.com/satyasm))

That's what all the systems with "login with Facebook, Google, X (Twitter), GitHub" use underneath.

### OAuth 1 { #oauth-1 }

There was an OAuth 1, which is very different from OAuth2, and more complex, as it included direct specifications on how to encrypt the communication.

It is not very popular or used nowadays.

OAuth2 doesn't specify how to encrypt the communication, it expects you to have your application served with HTTPS.

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.
