[cap-ang]

List of Changes

• Add new status PAYING when DELETE receipt/timer is received (called at time of ClosePayment inbound)

Motivation and Context

For the DWISP component, it is necessary to have a status that indicates that a payment is between the ClosePayment and paSendRTV2 since should not be sent a receipt-ko, although SPO is sent late, for payments awaiting SendPaymentOutcome and thus a paSendRTV2

How Has This Been Tested?
