 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.
+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.

-WellRESTed version 4 allows a Router to have a set of middleware to dispatch whenever it finds a route that matches. This middleware runs before the handler for the matched route, and only if a route matches.
+WellRESTed allows a Router to have a set of middleware to dispatch whenever it finds a route that matches. This middleware runs before the handler for the matched route, and only when a route matches.
 
-This feature allows you to build a site where some sections use certain middleware and other do not. For example, suppose your site has a public section that does not require authentication and a section that does require authentication. We can use a different router for each section, and provide authentication middleware on only the router for the private area.
