• Added accountType to SCPReceiptDetails.
• Added SCPDeviceTypeWisePosE to SCPDeviceType.
• Deprecated the SCPDiscoveryConfiguration initializers that require that you specify the device type to discover and replaced them with initializers that only require that you specify the discovery method. More specifically, if you use any of these SCPDiscoveryConfiguration initializers, you should replace them with the corresponding versions:
  • initWithDeviceType:simulated: → initWithDiscoveryMethod:simulated:
  • initWithDeviceType:discoveryMethod:simulated: → initWithDiscoveryMethod:simulated:
  • initWithDeviceType:discoveryMethod:locationId:simulated: → initWithDiscoveryMethod:locationId:simulated:
• Added a new interface in the example app to grant easy access to receipts
