  | -------------------- | ----------------------------------------------------------------- | ------- | ---------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
  | Party Reference      | `grandcentral-party-reference-api`                                | 2.3.0   | Added groups and identifiers to the party reference schema             | The party reference schema now includes party groups and identifiers. The `partyRelationship` schema includes directory information and is aligned with the party event specification.                                                                                                                                                                                                                                                                                                                                                    |
  | Loan                 | `grandcentral-loan-api`                                           | 1.3.1   | Extended the loan API card linkage endpoints for credit card use cases | The loan API card linkage request and response formats are restructured to support credit card use cases, with added pagination and `customFields`. The balances query parameter accepts multiple `loanIds`. On fee arrangements, the `feeCustomFields` property is renamed to `customFields` to match the standard property used elsewhere in the loan API.                                                                                                                                                                              |
  | Product Matching     | `grandcentral-product-matching-api`                               | 1.0.8   | Added settlement account details to the maturity calculation request   | The `maturityCalculationRequest` now accepts an optional `settlementAccount` with `payInAccount` and `payOutAccount`, each using the `accountIdentification` shape (`bban`, `iban`, `upic`, or `accountNumber`). When you provide `settlementAccount`, both `payInAccount` and `payOutAccount` are required, and each must be a non-empty `accountIdentification` object.                                                                                                                                                                 |
  | Fraud Detection      | `grandcentral-fraud-detection-api`                                | 1.4.0   | Added a session-events streaming endpoint to the fraud detection API   | The fraud detection API adds `POST /stream/session-events` for real-time session-events streaming. The change includes a new `feedzaiStreaming` vendor block and extended device, browser, and decision schemas.                                                                                                                                                                                                                                                                                                                          |
  | Direct Debit Mandate | `grandcentral-direct-debit-mandate-api`                           | 1.0.6   | Added mandate status and custom fields to the direct debit mandate API | The `directDebitMandateReference` schema adds `directDebitMandateStatus` to capture record state. The API adds `customFields` to the search request, search response, get-by-id response, and terminate request schemas, using a reusable custom field schema for key-value pairs.                                                                                                                                                                                                                                                        |
