New Features

Functional Enhancements

RPC Additions

• When querying ForwardingEvents logs, the response now include the incoming and outgoing htlc indices of the payment circuit. The indices are only available for forwarding events saved after v0.20.

With the option to specify multiple channels this control can be extended to multiple hops leading to the node.

lncli Additions
