-The OAuth role won't update on an upgrade. However the Alpha role and sql_lab roles (Of which OAuth is largely the union of) may change. Looking for differences between OAuth and the union of Alpha and sql_lab roles may be the solution to new permissions problems.
+The OAuth role won't update on an upgrade. However the Alpha role and sql_lab roles may change. If a permissions problem manifests following an upgrade, looking for differences between the current and former Alpha and sql_lab roles may show a permission that can be added to OAuth to solve the issue.
