Release Notes

Protocol Extensions

Zero-Conf Channel Opens

• Introduces support for zero-conf channel opens and non-zero-conf option_scid_alias channels.

Build system

• Add the release build directory to the .gitignore file to avoid the release binary digest to be different whether that folder exists or not.

lncli

• Add payment_addr flag to buildroute so that the mpp record of the route can be set correctly.

• Hop hints are now opt in when using lncli addholdinvoice. Users now need to explicitly specify the --private flag.

• Add chan_point flag to updatechanstatus and abandonchannel to offer a convenient way to specify the channel to be updated.

• Add ignore_pair flag to queryroutes to allow a user to request that specific directional node pairs be ignored during the route search.

Database

• Delete failed payment attempts once payments are settled, unless specified with keep-failed-payment-attempts flag.

Documentation

• Add minor comment on subscribe/cancel/lookup invoice parameter encoding.
• Log pubkey for peer related messages.

RPC Server

• Add previous_outpoints to GetTransactions RPC.

• Fix P2TR support in ComputeInputScript.

• Add wallet reserve RPC & field in wallet balance.

• The RPC middleware interceptor now also allows requests to be replaced instead of just responses. In addition to that, errors returned from lnd can now also be intercepted and changed by the middleware.

• The signrpc.SignMessage and signrpc.VerifyMessage now supports Schnorr signatures.

• A new flag skip_temp_err is added to SendToRoute. Set it to true so the payment won't be failed unless a terminal error has occurred, which is useful for constructing MPP.

• Add a message to the RPC MW registration flow so that the server can indicate to the client that it has completed the RPC MW registration.

Bug Fixes

• Fixed data race found in TestSerializeHTLCEntries.

• Fixed a bug in the SignPsbt RPC that produced an invalid response when signing a NP2WKH input.

• Update the urfave/cli package because of a flag parsing bug.

• DisconnectPeer no longer interferes with the peerTerminationWatcher. This previously caused force closes.

• The HtlcSwitch now waits for a ChannelLink to stop before replacing it. This fixes a race condition.

• Integration tests now always run with nodes never deleting failed payments.

• Fixes a key scope issue preventing new remote signing setups to be created with v0.15.0-beta.

• Re-initialise registered middleware index lookup map after removal of a registered middleware

Code Health

Code cleanup, refactor, typo fixes

• Migrate instances of assert.NoError to require.NoError.

• Enforce the order of rpc interceptor execution to be the same as the order in which they were registered.

Tooling and documentation

• An .editorconfig file was added to autoconfigure most text editors to respect the 80 character line length and to use 8 spaces as the tab size. Rules for Visual Studio Code were also added. And finally, the code formatting rules were extracted into their own document.
