+# UPGRADE GUIDE
+
+## 1.0.0 (voltaire)
+
+* `@REST\Association` has been renamed to `@REST\ExposedAssociation`
+* Routing changes
+  * Router can now be used in child-routes.
+  * Routes of type `ResourceGraphRoute` **must not** contain a literal prefix.
+  * For example, this route is invalid: `/api/v3/data/users` (it will never match)
+  * Static (literal) parts of the route **must** now be defined separately as part of parent route, for example:
+
+````php
+// routes => array(
+    // this will work with: /api/v3/data/users
+    'rest-data' => array(
+        'type'         => 'Literal',
+        'options' => array(
+            'route'    => '/api/v3/data'
+        ),
+        'child_routes' => array(
+            'users'    => array(
+                'type'    => 'ResourceGraphRoute',
+                'options' => array(
+                    'route'    => '/users',
+                    'resource' => 'Application\Repository\UserRepository'
+                )
+            ),
+        )
+    )
+````
+
+* Configuration changes
+  * `resource_metadata` key is now removed and all sub-keys have been moved to the main configuration array
+    (i.e. `[zfr_rest][resource_metadata][cache]` becomes `[zfr_rest][cache]`
+  * `cache` now expects a name of a service which will be loaded from ServiceManager. The service must
+    implement `Metadata\Cache\CacheInterface`
