We've relaxed parameter validation rules in the [DDoS Protection API](https://www.fastly.com/documentation/reference/api/ddos-protection/) to allow for easier addition of new values without requiring API updates. This affects the `ddos_protection_action` parameter in the [events](https://www.fastly.com/documentation/reference/api/ddos-protection/#ddos-protection-event-list) and [event rules](https://www.fastly.com/documentation/reference/api/ddos-protection/#ddos-protection-event-rule-list) endpoints, as well as the `ddos_protection_traffic_attribute` parameter in the [traffic stats](https://www.fastly.com/documentation/reference/api/ddos-protection/#ddos-protection-traffic-stats-rule-get) endpoint. Supported values will be documented in each endpoint's description.
