Release Notes

DB

• Split channeldb UpdateInvoice implementation logic in different update types.

Watchtowers

• Let the task pipeline only carry wtdb.BackupIDs instead of the entire retribution struct. This reduces the amount of data that needs to be held in memory.
• Replace in-mem task pipeline with a disk-overflow queue

Misc

• Ensure that both the byte and string form of a TXID is populated in the lnrpc.Outpoint message.

• Fix Benchmark Test (BenchmarkReadMessage/Channel_Ready) in the lnwire package

• Fix unit test flake (TestLightningWallet) in the neutrino package via version bump of btcsuite/btcwallet

RPC

• SendOutputs now adheres to the anchor channel reserve requirement.

• Enforce provided fee rate is no less than the relay or minimum mempool fee when calling OpenChannel, CloseChannel, SendCoins, and SendMany.

• The UpdateNodeAnnouncement API can no longer be used to set/unset protocol features that are defined by LND.

• Neutrinorpc getblockhash has been deprecated. Endpoint has been moved to the chainrpc sub-server.

  Custom node announcement feature bits can also be specified in config using the dev build tag and --protocol.custom-nodeann, --protocol.custom-init and --protocol.custom-invoice flags to set feature bits for various feature "sets", as defined in BOLT 9.

• OpenChannel now accepts an optional memo argument for specifying a helpful note-to-self containing arbitrary useful information about the channel.

Misc

• Generate default macaroons independently on wallet unlock or create.

• Restore support for PKCS8-encoded cert private keys.

Code Health

• Updated our fork for serializing protobuf as JSON to be based on the latest version of google.golang.org/protobuf instead of the deprecated github.com/golang/protobuf/jsonpb module.

Testing

• Started running fuzz tests in CI.

• Derandomized the BOLT 8 fuzz tests.

• Added fuzz tests for signature parsing and conversion.

• Simplify fuzz tests using the require package.

lncli

• Added ability to use ENV variables to override lncli global flags. Flags will have preference over ENVs.

Bug Fix

• Make sure payment stream returns all the events by subscribing it before sending.
