<Update label="7-21-2026" tags={["API"]}>
  ## <span><Icon icon="wrench" iconType="solid" /> Enhancements </span>

  <b>Error responses now include `clientRequestId` and `correlationId`</b>

  Non-200 error responses from the `/v3` API now include two optional tracing fields. The `clientRequestId` field echoes back the value supplied in the request. The `correlationId` field identifies the request flow when a correlation ID is available. Use them to correlate error responses with the originating request and the request flow. Prove omits `clientRequestId` when the request didn't include one and omits `correlationId` when none is available for the flow. Success responses are unchanged.
</Update>

<Update label="6-23-2026" tags={["Pre-Fill"]}>
  ## <span><Icon icon="wrench" iconType="solid" /> Enhancements </span>

  <b>More accurate PO Box filtering for Pre-Fill</b>

  PO Box detection is now more exact for US Pre-Fill verifications. PO Box addresses are still excluded by default from the addresses returned in `/v3/verify` Pre-Fill responses. Contact your Prove representative if you need PO Box addresses included in your configuration.

  If you have any questions or need further guidance with the iOS SDK update, please submit a support ticket through the Developer Portal or contact your Prove representative.
