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.

  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.

Misc

• Generate default macaroons independently on wallet unlock or create.

• Restore support for PKCS8-encoded cert private keys.

• Re-encrypt/regenerate all macaroon DB root keys on ChangePassword/GenerateNewRootKey respectively.

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

• Added fuzz tests for signature parsing and conversion.
