** improved ETag/Last-Modified support in `WebRequest`.
* JavaScript view templating built on Nashorn and JDK 1.8, see `ScriptTemplateViewResolver`.
* Custom `@RequestMapping` annotations.
* Public methods in `AbstractHandlerMethodMapping` to register and unregister request mappings at runtime.
* 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.

** 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.
* Heart-beats and a SpEL expression 'selector' header for subscriptions with `SimpleBrokerMessageHandler`.
* STOMP client for use over TCP and WebSocket, see <<websocket-stomp-client>>.
* `@SendTo` and `@SendToUser` can contain destination variable placeholders.
* Jackson's `@JsonView` supported for return values on `@MessageMapping` and `@SubscribeMapping` methods.

`@MessageMapping` and `@SubscribeMapping` methods.
