• Added error, SCPErrorInvalidRequiredParameter, reported when a required parameter was invalid or missing. This does not replace more specific errors like SCPErrorNilPaymentIntent and SCPErrorProcessInvalidPaymentIntent, but will be returned when other unexpected inputs were invalid, such as passing a nil or empty string as the client secret into retrievePaymentIntent:completion:.
• Bug fix: Previously, SCPErrorUnexpectedSdkError was returned when retrying processPaymentIntent: after a previous processPaymentIntent: completed with an error. Now, this behavior should not fail.
• Bug fix: Location requests no longer time out if Terminal is initialized on a background thread. Previously, even if the device had an accurate location a location request could time out and cause a 5 second delay during processPayment. This was reported in #143.
