+* New `RequestBodyAdvice` extension point and a built-in implementation to support Jackson's `@JsonView`
+  on`@RequestBody` method arguments.
+* `HandlerMethod` as a method argument on `@ExceptionHandler` methods, especially
+  handy in `@ControllerAdvice` components.
+* `java.util.concurrent.CompletableFuture` as an @Controller method return value type.
+* Byte-range request support in `HttpHeaders` and for serving static resource.
+* `@ResponseStatus` detected on nested exceptions.

+* Custom "baseUrl" alternative for methods in MvcUriComponentsBuilder.
+
+
+=== WebSocket Messaging Improvements

+** new `SimpUserRegistry` exposed as a bean named "userRegistry".
+** sharing of presence information across cluster of servers (see broker relay config options).
+* Resolve user destinations across cluster of servers (see broker relay config options).
+* `StompSubProtocolErrorHandler` extension point to customize and control STOMP ERROR frames to clients.
+* Global `@MessageExceptionHandler` methods via `@ControllerAdvice` components.

+* Jackson's `@JsonView` supported for return values on `@MessageMapping` and `@SubscribeMapping` methods.
