Request body: limited chunk extensions and trailer headers. Previously, arbitrary amounts of chunk extensions and trailer headers were accepted and skipped. Despite being under limit_conn / limit_req limits (if configured), this can be a DoS vector, so it is now limited by the client_max_body_size limit. Reported by Bartek Nowotarski.
