 * [Changed] The private beta API for https://stripe.com/docs/payments/finalize-payments-on-the-server has changed:
   * If you use `IntentConfiguration(..., confirmHandler:)`, the confirm handler now has an additional `shouldSavePaymentMethod: Bool` parameter that you should ignore.
   * If you use `IntentConfiguration(..., confirmHandlerForServerSideConfirmation:)`, use `IntentConfiguration(..., confirmHandler:)` instead. Additionally, the confirm handler's first parameter is now an `STPPaymentMethod` object instead of a String id. Use `paymentMethod.stripeId` to get its id and send it to your server.
+* [Fixed] Fixed PKR currency formatting.
