-=== Content negotiation improvements
-A `ContentNegotiationStrategy` is now available for resolving the requested media types
-from an incoming request. The available implementations are based on the file extension,

 ==== Configuring Content Negotiation
-Staring with Spring Framework 3.2, you can configure how Spring MVC determines the
-requested media types from the client for request mapping as well as for content
-negotiation purposes. The available options are to check the file extension in the
-request URI, the "Accept" header, a request parameter, as well as to fall back on a
-default content type. By default, file extension in the request URI is checked first and
-the "Accept" header is checked next.

 For file extensions in the request URI, the MVC Java config and the MVC namespace,
 automatically register extensions such as `.json`, `.xml`, `.rss`, and `.atom` if the
 corresponding dependencies such as Jackson, JAXB2, or Rome are present on the classpath.
 Additional extensions may be not need to be registered explicitly if they can be
 discovered via `ServletContext.getMimeType(String)` or the __Java Activation Framework__
-(see `javax.activation.MimetypesFileTypeMap`).
