 ### Added
 
+* Change the type of `Extensions` from `Mapping[Str, Any]` to `MutableMapping[Str, Any]`. (#2803)
 * Add `socket_options` argument to `httpx.HTTPTransport` and `httpx.AsyncHTTPTransport` classes. (#2716)
 * The `Response.raise_for_status()` method now returns the response instance. For example: `data = httpx.get('...').raise_for_status().json()`. (#2776)
