 Change history of go-restful
 =
+2016-11-26
+- Default change! now use CurlyRouter (was RouterJSR311)
+- Default change! no more caching of request content
+- Default change! do not recover from panics
+
+2016-09-22
+- fix the DefaultRequestContentType feature
+
 2016-02-14
 - take the qualify factor of the Accept header mediatype into account when deciding the contentype of the response
 - add constructors for custom entity accessors for xml and json

 This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
 
-	restful.DefaultContainer.Router(CurlyRouter{})
-
-The default router is the RouterJSR311 which is an implementation of its spec (http://jsr311.java.net/nonav/releases/1.1/spec/spec.html).
-However, it uses regular expressions for all its routes which, depending on your usecase, may consume a significant amount of time.
-The CurlyRouter implementation is more lightweight that also allows you to use wildcards and expressions, but only if needed.
-
-	restful.DefaultContainer.DoNotRecover(true)
+	restful.DefaultContainer.DoNotRecover(false)
 
 DoNotRecover controls whether panics will be caught to return HTTP 500.
-If set to true, Route functions are responsible for handling any error situation.
-Default value is false; it will recover from panics. This has performance implications.
-
-	restful.SetCacheReadEntity(false)
-
-SetCacheReadEntity controls whether the response data ([]byte) is cached such that ReadEntity is repeatable.
-If you expect to read large amounts of payload data, and you do not use this feature, you should set it to false.
+If set to false, the container will recover from panics.
+Default value is true
