# Release Notes: v2023-08-01

> Changes and Improvements made in the version 2023-08-01

Following are the key changes made in the version 2023-08-01:

<Steps>
  <Step title="New header in API Response">
    New header "x-deprecated-at" is added in the API response which will let you
    know the date when the used version is going to get deprecated.
  </Step>

  <Step title="Cashfree IDs type change [BREAKING]">
    All cashfree IDs like `cf_order_id`, `cf_payment_id`, `cf_refund_id` etc are
    now in **string** format instead of **integer** (in older versions).
  </Step>

  <Step title="Order Entity Changes">
    1. We have removed payments, refunds, settlements urls from order entity. 2.
       `customer_uid` part of customer\_details in order entity. This is the unique
       identifier of the customer created at Cashfree. You can create customer at
       cashfree using [Create Customer API](/api-reference/payments/previous/v2023-08-01/customers/create) 3.
       `order_status` can have two more values - "TERMINATED" and
       "TERMINATION\_REQUESTED". Find the complete list of order statuses
       [here](/v4/docs/transaction-lifecycle#order-state-details) 4. No longer
       support for `notify_url` in Create Order API. You can [configure
       webhooks](/api-reference/payments/previous/v2023-08-01/payments/webhooks) from dashboard instead.
  </Step>

  <Step title="New Order Termination API">
    We have released a new API to terminate an Order. Find API details - [Order
    Termination API.](/v4/reference/pgterminateorder)
  </Step>

  <Step title="New Customer APIs">
    We have released Customer APIs to let merchants create and manager their
    customers. Find more about this here - [Customer
    Management](/api-reference/payments/previous/v2023-08-01/customers/create)
  </Step>

  <Step title="New SPOS APIs">
    Find newly released [SPOS APIs](/v4/reference/create-terminal-transaction)
  </Step>

  <Step title="CF Refund IDs">
    Earlier cf\_refund\_id used to start with a prefix "refund\_". In this
    version, you will not get that prefix and cf\_refund\_id will be directly be
    the id without any prefix. Example - OLD cf\_refund\_id = "refund\_41805719" ,
    NEW cf\_refund\_id = "41805719"
  </Step>
