-        The configuration option `config.serve_static_assets` has been renamed
-        to `config.serve_static_files` to clarify its role (it merely enables
-        serving everything in the `public` folder and is unrelated to the asset
-        pipeline). The `serve_static_assets` alias will be removed in Rails 5.0.
-        Please migrate your configuration files accordingly.
