Release Notes

Bug Fixes

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.

  • The lncli addinvoice --blind command now has the option to include a chained channels incoming list --blinded_path_incoming_channel_list which gives users the control of specifying the channels they prefer to receive the payment on. With the option to specify multiple channels this control can be extended to multiple hops leading to the node.

  • The lnrpc.ForwardingHistory RPC method now supports filtering by incoming_chan_ids and outgoing_chan_ids. This allows to retrieve forwarding events for specific channels.
