# Release Notes

## 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](https://github.com/lightningnetwork/lnd/pull/6676).

## `lncli`

* [Add `payment_addr` flag to
  `buildroute`](https://github.com/lightningnetwork/lnd/pull/6576)
  so that the mpp record of the route can be set correctly.

* [Hop hints are now opt in when using `lncli
  addholdinvoice`](https://github.com/lightningnetwork/lnd/pull/6577). Users now
  need to explicitly specify the `--private` flag.

## Database

* [Delete failed payment attempts](https://github.com/lightningnetwork/lnd/pull/6438)
  once payments are settled, unless specified with `keep-failed-payment-attempts` flag.

## Documentation

* [Add minor comment](https://github.com/lightningnetwork/lnd/pull/6559) on
  subscribe/cancel/lookup invoice parameter encoding.
* [Log pubkey for peer related messages](https://github.com/lightningnetwork/lnd/pull/6588).
  
## RPC Server

* [Add previous_outpoints to 
  `GetTransactions` RPC](https://github.com/lightningnetwork/lnd/pull/6321).

* [Fix P2TR support in
  `ComputeInputScript`](https://github.com/lightningnetwork/lnd/pull/6680).

* [Add wallet reserve RPC & field in wallet
  balance](https://github.com/lightningnetwork/lnd/pull/6592).

## Bug Fixes

* Fixed data race found in
  [`TestSerializeHTLCEntries`](https://github.com/lightningnetwork/lnd/pull/6673).

* [Fixed a bug in the `SignPsbt` RPC that produced an invalid response when
  signing a NP2WKH input](https://github.com/lightningnetwork/lnd/pull/6687).

* [Update the `urfave/cli`
  package](https://github.com/lightningnetwork/lnd/pull/6682) because of a flag
  parsing bug.

* [DisconnectPeer no longer interferes with the peerTerminationWatcher. This previously caused
  force closes.](https://github.com/lightningnetwork/lnd/pull/6655)

* [The HtlcSwitch now waits for a ChannelLink to stop before replacing it. This fixes a race
  condition.](https://github.com/lightningnetwork/lnd/pull/6642)

### Code cleanup, refactor, typo fixes

* [Migrate instances of assert.NoError to require.NoError](https://github.com/lightningnetwork/lnd/pull/6636).
