### Update a Hero with `HeroUpdate` { #update-a-hero-with-heroupdate }

We can **update a hero**. For this we use an HTTP `PATCH` operation.

And in the code, we get a `dict` with all the data sent by the client, **only the data sent by the client**, excluding any values that would be there just for being the default values. To do it we use `exclude_unset=True`. This is the main trick. 🪄

 *  New: `okhttp-sse` is an early preview of Server-Sent Events (SSE). This feature is incomplete
    and is only suitable for experimental use.
 *  New: MockWebServer now supports client authentication (mutual TLS). Call `requestClientAuth()`
    to permit an optional client certificate or `requireClientAuth()` to require one.
 *  New: `RecordedRequest.getHandshake()` returns the HTTPS handshake of a request sent to
    `MockWebServer`.
