+3.0 Migration Guide
+###################
+
+Authorization 3.0 contains new features and a few breaking changes.
+
+Breaking Changes
+================
+
+The following interfaces now have appropriate parameter and return types added:
+
+- ``AuthorizationServiceInterface``
+- ``IdentityInterface``
+- ``BeforePolicyInterface``
+- ``RequestPolicyInterface.php``
+- ``ResolverInterface``
+
+Multiple optional arguments for ``applyScope``
+----------------------------------------------
+
+``IdentityInterface::applyScope`` as well as ``AuthorizationServiceInterface::applyScope``
+allow multiple optional arguments to be added.
+
+Removed methods
+---------------
+
+- ``AuthorizationService::resultTypeCheck`` - has been replaced with an ``assert()`` call
+
