# Bug Fixes
* [LND now sets the `BADONION`](https://github.com/lightningnetwork/lnd/pull/7937)
bit when sending `update_fail_malformed_htlc`. This avoids a force close
with other implementations.
# New Features
## Functional Enhancements
sweeper: relax anchor sweeping when there's no deadline pressure (#7965) * sweep: use longer variable name for clarity in `addToState` * sweeper: add more docs and debug logs * sweep: prioritize smaller inputs when adding wallet UTXOs This commit sorts wallet UTXOs by their values when using them for sweeping inputs. This way we'd avoid locking large UTXOs when sweeping inputs and also provide an opportunity to aggregate wallet UTXOs. * contractcourt+itest: relax anchor sweeping for CPFP purpose This commit changes from always sweeping anchor for a local force close to only do so when there is an actual time pressure. After this change, a forced anchor sweeping will only be attempted when the deadline is less than 144 blocks. * docs: update release notes * itest: update test `testMultiHopHtlcLocalChainClaim` to skip CPFP Since we now only perform CPFP when both the fee rate is higher and the deadline is less than 144, we need to update the test to reflect that Bob will not CPFP the force close tx for the channle Alice->Bob. * itest: fix `testMultiHopRemoteForceCloseOnChainHtlcTimeout` * itest: update related tests to reflect anchor sweeping This commit updates all related tests to reflect the latest anchor sweeping behavior. Previously, anchor sweeping is always attempted as CPFP when a force close is broadcast, while now it only happens when the deadline is less than 144. For non-CPFP purpose sweeping, it will happen after one block is mined after the force close transaction is confirmed as the anchor will be resent to the sweeper with a floor fee rate, hence making it economical to sweep.

- Previously, when a channel was force closed locally, its anchor was always
force-swept when the CPFP requirements are met. This is now
[changed](https://github.com/lightningnetwork/lnd/pull/7965) to only attempt
CPFP based on the deadline of the commitment transaction. The anchor output
will still be offered to the sweeper during channel force close, while the
actual sweeping won't be forced(CPFP) unless a relevant HTLC will timeout in
144 blocks. If CPFP before this deadline is needed, user can use `BumpFee`
instead.

gomod: update btcwallet version (#8019)
2023-10-16 09:14:56 +02:00
- When facing a large mempool, users may experience deteriorated performance,
which includes slow startup and shutdown, clogging RPC response when calling
`getinfo`, and CPU spikes. This is now improved with [the upgrade to the
latest `btcwallet`](https://github.com/lightningnetwork/lnd/pull/8019). In
addition, it's strongly recommended to upgrade `bitcoind` to version `v24.0`
and above to take advantage of the new RPC method `gettxspendingprevout`,
which will further decrease CPU usage and memory consumption.
