Release Notes

Routing

• The default CLTV delta delay has been increased from 40 blocks to 80 blocks.

Wallet

• The logging around transaction broadcast failures has been improved by always logging the causing error and the raw transaction as hex.

lncli

• The lncli wallet psbt fund command now allows users to specify the --min_confs flag.

• Add time_lock_delta overflow check for UpdateChannelPolicy that ensure time_lock_delta is greater or equal than 0 and less or equal than 65535

• Added ability to backup, verify and restore single channels to and from a file on disk.

• Add a fundmax flag to openchannel to allow for the allocation of all funds in a wallet towards a new channel opening.

Watchtowers

• Fix Address iterator panic
• Allow caller to filter sessions at the time of reading them from disk
• Clean up sessions once all channels for which they have updates for are closed. Also start sending the DeleteSession message to the tower.
• Don't load exhausted sessions when not needed. Also add a new exclude_exhausted_sessions boolean flag to the relevant lncli wtclient commands.
• Recover from StateUpdateCodeClientBehind error after data loss.

Build

• ldflags were being incorrectly passed

Misc

• Return FEE_INSUFFICIENT before checking balance for incoming low-fee HTLCs..

• Optimize script allocation size in order to save memory.

• When resolving outgoing HTLCs onchain, the HTLC timeout resolver will now monitor mempool for faster preimage extraction.

Spec

• Add test vectors for option_zero_fee_htlc_tx

RPC

• A debug log has been added to lnrpc so the node operator can know whether a certain request has happened or not.

• Add peer_scid_alias to the response of listchannels

• Message funding_locked has been renamed to channel_ready internally to match the specs update. This should not change anything for the users since the message type(36) stays unchanged, except in the logging all the appearance of funding_locked replated experssion is replaced with channel_ready.

Bug Fixes

• Fix a bug where lnd crashes when psbt data is not fully available.

• Put back P2TR as default change type in batch_open_channel.

• Fix log output.

• Channels opened with custom fee policies are now able to forward payments correctly without needing to restart first.

• Fix a bug where the funding manager would error out if no persisted initial forwarding policy is found for a channel.

• The internal rebroacaster will no longer continue to rebroadcast stale sweeper transactions (have a conflict mined or in the mempool).
