*   Use `after_destroy_commit` instead of `before_destroy` for purging
    attachments when a record is destroyed.

*   Force `:attachment` disposition for specific, configurable content types.
    This mitigates possible security issues such as XSS or phishing when
    serving them inline. A list of such content types is included by default,
    and can be configured via `content_types_to_serve_as_binary`.
