- Kubelet TCP and HTTP probes are now more effective using networking resources:
  conntrack entries, sockets. This is achieved by reducing the `TIME-WAIT` state
  of the connection to 1 second, instead of the defaults 60 seconds. This allows

- The job controller removes running pods when the number of completions is achieved. ([#99963](https://github.com/kubernetes/kubernetes/pull/99963), [@alculquicondor](https://github.com/alculquicondor))

- Achieved 2X performance improvement on both required and preferred PodAffinity. ([#76243](https://github.com/kubernetes/kubernetes/pull/76243), [@Huang-Wei](https://github.com/Huang-Wei))

- Setting loadBalancerClass in load balancer type of service is available with this PR. 
  Users who want to use a custom load balancer can specify loadBalancerClass to achieve it. ([#98277](https://github.com/kubernetes/kubernetes/pull/98277), [@XudongLiuHarold](https://github.com/XudongLiuHarold)) [SIG API Machinery, Apps, Cloud Provider and Network]

#### Forbid Extra Query (Cookie, Header) Parameters

Use Pydantic models to restrict extra values for `Query` parameters (also applies to `Header` and `Cookie` parameters).

To achieve it, use Pydantic's `model_config = {"extra": "forbid"}`:

```python
from typing import Annotated, Literal

from fastapi import FastAPI, Query
from pydantic import BaseModel, Field

app = FastAPI()
