+    [BUG FIXES]
+    - Merged the pull-request #13, which fixed an issue where
+      the behavior of role method confliction was different
+      from Moose. This change might affect your existing code
+      so the major version has incremented.
+      See t/030_roles/role_conflict_and_inheritance.t for details.
