### Webhooks

* 🌱 **Fully custom HTTP headers**: You can now [configure Webhooks](/webhook-custom-http-headers) to send with fully custom HTTP headers. Previously, you could only choose custom header keys from a pre-set list. This feature is only enabled for enterprise customers.
* 🍃 **Support HTTP 204 responses**: Webhook events now advance from `pending` to `completed` when your server returns an HTTP 204 status.

### Accounts & Transactions

* 🍃 **Asynchronous redaction of related resources**: Previously, the [Account](/api-reference/accounts/redact-an-account) and [Transaction](/api-reference/transactions/redact-a-transaction) redaction endpoints would redact the primary object (Account or Transaction) as well as any related resources (Inquiries, Verifications, etc.) synchronously. Now these endpoints redact the primary object synchronously and redact any related resources asynchronously. The `account.redacted` and `transaction.redacted` events are only emitted after all objects are redacted. This improves performance.
