#### `Header` Parameter Models

Use Pydantic models for `Header` parameters:

```python
from typing import Annotated

from fastapi import FastAPI, Header
from pydantic import BaseModel

app = FastAPI()


class CommonHeaders(BaseModel):
    host: str
    save_data: bool

pkg math/bits, func Rem(uint, uint, uint) uint
pkg math/bits, func Rem32(uint32, uint32, uint32) uint32
pkg math/bits, func Rem64(uint64, uint64, uint64) uint64
pkg mime/multipart, method (*Reader) NextRawPart() (*Part, error)
pkg net/http, method (Header) Values(string) []string
pkg net/http, type Transport struct, DialTLSContext func(context.Context, string, string) (net.Conn, error)
pkg net/http/httptest, type Server struct, EnableHTTP2 bool

pkg syscall (freebsd-riscv64), type InterfaceAddrMessage struct, Header IfaMsghdr #53466
pkg syscall (freebsd-riscv64), type InterfaceAnnounceMessage //deprecated #53466
pkg syscall (freebsd-riscv64), type InterfaceAnnounceMessage struct #53466
pkg syscall (freebsd-riscv64), type InterfaceAnnounceMessage struct, Header IfAnnounceMsghdr #53466
pkg syscall (freebsd-riscv64), type InterfaceMessage //deprecated #53466

# Release 2.17.1

### Bug Fixes and Other Changes

* Add necessary header files in the aar library. These are needed if developers build apps with header files unpacked from tflite aar files from maven.
* Implement Name() for GCSWritableFile to fix the profiler trace viewer cache file generation.
