+UPGRADE FROM 1.0 TO 1.1
+=======================
+
+Deprecated `RoutingBundle\Document\Route` and `RedirectRoute` in favor of
+`RoutingBundle\Doctrine\Phpcr\Route` resp. `RedirectRoute`.
+
+PHPCR specific configurations moved into
+
+    dynamic:
+        phpcr_provider:
+            use_sonata_admin: auto
+            manager_registry: ~
+            manager_name: ~
+            route_basepath: ~
+            content_basepath: ~
+
+You need to at least set `phpcr_provider: ~` to have the PHPCR provider loaded.
+
+Dropped redundant unused `routing_repositoryroot` configuration.
