# Release Notes

Hono v4.9.0 is now available!

This release introduces several enhancements and utilities.

The main highlight is the new `parseResponse` utility that makes it easier to work with RPC client responses.

## parseResponse Utility

The new `parseResponse` utility provides a convenient way to parse responses from Hono RPC clients (`hc`). It automatically handles different response formats and throws structured errors for failed requests.

```ts
import { parseResponse, DetailedError } from 'hono/client'

// result contains the parsed response body (automatically parsed based on Content-Type)
const result = await parseResponse(client.hello.$get()).catch(
  // parseResponse automatically throws an error if response is not ok
  (e: DetailedError) => {
    console.error(e)
  }
)
```

This makes working with RPC client responses much more straightforward and type-safe.

Thanks @NamesMT!
