 ### Network retries
 
-Automatic network retries can be enabled with the `maxNetworkRetries` config option.
-This will retry requests `n` times with exponential backoff if they fail due to an intermittent network problem.
-[Idempotency keys](https://stripe.com/docs/api/idempotent_requests) are added where appropriate to prevent duplication.
+As of [v13](https://github.com/stripe/stripe-node/releases/tag/v13.0.0) stripe-node will automatically do one reattempt for failed requests that are safe to retry. Automatic network retries can be disabled by setting the `maxNetworkRetries` config option to `0`. You can also set a higher number to reattempt multiple times, with exponential backoff. [Idempotency keys](https://stripe.com/docs/api/idempotent_requests) are added where appropriate to prevent duplication.
