  - |
    The default value of ``swift::proxy::pipeline`` has been updated to enable
    some fundamental middlewares by default.
    Because of this change, the following classes should be included unless
    the pipeline parameter is explicitly set.

    - ``swift::proxy::catch_errors``
    - ``swift::proxy::gatekeeper``
    - ``swift::proxy::proxy_logging``
    - ``swift::proxy::listing_formats``
    - ``swift::proxy::copy``
