-Changes from Version 3
-======================
-
-If your project uses WellRESTed version 3, you can most likely upgrade to to version 4 without making any changes to your code. However, there are a few changes that may affect some users, particularly users who have subclassed ``WellRESTed\Server`` or used custom implementations of other ``WellRESTed`` classes.
-
-Server Configuration
-^^^^^^^^^^^^^^^^^^^^
-
-Version 4 allows for easier customization of the server than version 3. Previously, to customize the Server, you would need to subclass Server and override protected methods that provided a default request, response, transmitter, etc. The Server in version 4 now provides the following setters for providing custom behavior:
-
-- ``setAttributes(array $attributes)``
-- ``setDispatcher(DispatcherInterface $dispatcher)``
-- ``setPathVariablesAttributeName(string $name)``
-- ``setRequest(ServerRequestInterface $request)``
-- ``setResponse(ResponseInterface $response)``
-- ``setTransmitter(TransmitterInterface $transmitter)``

-Message Customization
----------------------
+.. warning::
 
-In the example above, we passed a custom dispatcher to the server. You can also customize your server in other ways. For example, when the server reaches these end of its stack of middleware and has not had the response handled, it returns a blank 404 error response. You can customize this by passing a response to the server's ``setUnhandledResponse`` method.
-
-.. code-block:: php
-
-    $unhandled = (new Response(404))
-        ->withHeader('text/html')
-        ->withBody($fancy404message);
-    
-    $server->setUnhandledResponse($unhandled);
+    When you supply a custom Dispatcher, be sure to call ``Server::setDispatcher`` before you create any routers with ``Server::createRouter`` to allow the ``Server`` to pass you customer ``Dispatcher`` on to the newly created ``Router``.
