# Bug Fixes
* `closedchannels` now [successfully reports](https://github.com/lightningnetwork/lnd/pull/8800)
settled balances even if the delivery address is set to an address that
LND does not control.
* [SendPaymentV2](https://github.com/lightningnetwork/lnd/pull/8734) now cancels
the background payment loop if the user cancels the stream context.
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/8822) that caused
LND to read the config only partially and continued with the startup.
2024-07-18 08:52:42 +02:00
* [Avoids duplicate wallet addresses being
created](https://github.com/lightningnetwork/lnd/pull/8921) when multiple RPC
calls are made concurrently.
2024-07-11 22:26:15 +02:00
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/8896) that caused
LND to use a default fee rate for the batch channel opening flow.
2024-07-23 11:27:50 +02:00
* [Fixed](https://github.com/lightningnetwork/lnd/pull/8497) a case where LND
would not shut down properly when interrupted via e.g. SIGTERM. Moreover, LND
now shutsdown correctly in case one subsystem fails to startup.
2024-07-18 08:52:42 +02:00
* The fee limit for payments [was made
compatible](https://github.com/lightningnetwork/lnd/pull/8941) with inbound
fees.
2024-07-29 11:21:42 +02:00
* [Fixed](https://github.com/lightningnetwork/lnd/pull/8946) a case where
bumping an anchor channel closing was not possible when no HTLCs were on the
commitment when the channel was force closed.
* [Fixed](https://github.com/lightningnetwork/lnd/pull/8174) old payments that
are stuck inflight. Though the root cause is unknown, it's possible the
network result for a given HTLC attempt was not saved, which is now fixed.
Check
[here](https://github.com/lightningnetwork/lnd/pull/8174#issue-1992055103)
for the details about the analysis, and
[here](https://github.com/lightningnetwork/lnd/issues/8146) for a summary of
the issue.

# New Features
## Functional Enhancements
## RPC Additions
* The [SendPaymentRequest](https://github.com/lightningnetwork/lnd/pull/8734)
message receives a new flag `cancelable` which indicates if the payment loop
is cancelable. The cancellation can either occur manually by cancelling the
send payment stream context, or automatically at the end of the timeout period
if the user provided `timeout_seconds`.
2024-07-30 17:32:11 +08:00
* The [SendCoinsRequest](https://github.com/lightningnetwork/lnd/pull/8955) now
takes an optional param `Outpoints`, which is a list of `*lnrpc.OutPoint`
that specifies the coins from the wallet to be spent in this RPC call. To
send selected coins to a given address with a given amount,
```go
req := &lnrpc.SendCoinsRequest{
Addr: ...,
Amount: ...,
Outpoints: []*lnrpc.OutPoint{
selected_wallet_utxo_1,
selected_wallet_utxo_2,
},
}
SendCoins(req)
```
To send selected coins to a given address without change output,
```go
req := &lnrpc.SendCoinsRequest{
Addr: ...,
SendAll: true,
Outpoints: []*lnrpc.OutPoint{
selected_wallet_utxo_1,
selected_wallet_utxo_2,
},
}
SendCoins(req)
```
2024-07-06 14:01:40 +08:00
## lncli Additions
* [Added](https://github.com/lightningnetwork/lnd/pull/8491) the `cltv_expiry`
argument to `addinvoice` and `addholdinvoice`, allowing users to set the
`min_final_cltv_expiry_delta`.
* The [`lncli wallet estimatefeerate`](https://github.com/lightningnetwork/lnd/pull/8730)
command returns the fee rate estimate for on-chain transactions in sat/kw and
sat/vb to achieve a given confirmation target.
2024-07-30 17:32:11 +08:00
* [`sendcoins` now takes an optional utxo
flag](https://github.com/lightningnetwork/lnd/pull/8955). This allows users
to specify the coins that they want to use as inputs for the transaction. To
send selected coins to a given address with a given amount,
```sh
sendcoins --addr YOUR_ADDR --amt YOUR_AMT --utxo selected_wallet_utxo1 --utxo selected_wallet_utxo2
```
To send selected coins to a given address without change output,
```sh
sendcoins --addr YOUR_ADDR --utxo selected_wallet_utxo1 --utxo selected_wallet_utxo2 --sweepall
```

# Improvements
## Functional Updates
2024-07-19 16:12:06 +08:00
* A new field, `min_relay_feerate`, is [now
expected](https://github.com/lightningnetwork/lnd/pull/8891) in the response
from querying the external fee estimation URL. The new response should have
the format,
```json
{
"fee_by_block_target": {
"2": 5076,
"3": 4228,
"26": 4200
},
"min_relay_feerate": 1000
}
```
All units are `sats/kvB`. If the new field `min_relay_feerate` is not set,
the default floor feerate (1012 sats/kvB) will be used.
2024-07-29 14:12:37 -04:00
* Commitment fees are now taken into account when [calculating the fee
exposure threshold](https://github.com/lightningnetwork/lnd/pull/8824).
2024-07-22 10:35:14 +02:00
* [Allow](https://github.com/lightningnetwork/lnd/pull/8845) multiple etcd hosts
to be specified in db.etcd.host.
2024-07-06 14:01:40 +08:00
## RPC Updates
* [`xImportMissionControl`](https://github.com/lightningnetwork/lnd/pull/8779)
now accepts `0` failure amounts.
* [`ChanInfoRequest`](https://github.com/lightningnetwork/lnd/pull/8813)
adds support for channel points.
2024-07-02 12:25:18 +02:00
* [BuildRoute](https://github.com/lightningnetwork/lnd/pull/8886) now supports
inbound fees.
2024-07-06 14:01:40 +08:00
## lncli Updates
* [`importmc`](https://github.com/lightningnetwork/lnd/pull/8779) now accepts
`0` failure amounts.
* [`getchaninfo`](https://github.com/lightningnetwork/lnd/pull/8813) now accepts
a channel outpoint besides a channel id.
* [Fixed](https://github.com/lightningnetwork/lnd/pull/8823) how we parse the
`--amp` flag when sending a payment specifying the payment request.
## Code Health
2024-06-13 09:44:30 +02:00
* [Added](https://github.com/lightningnetwork/lnd/pull/8836) a new failure
reason `FailureReasonCanceled` to the list of payment failure reasons. It
indicates that a payment was manually cancelled by the user.
2024-08-05 11:38:29 +02:00
* [Update the version](https://github.com/lightningnetwork/lnd/pull/8974) of
[falafel](https://github.com/lightninglabs/falafel) used to generate JSON/wasm
stubs. This latest version of falafel also supports proto3 optional fields.

2024-07-06 14:01:40 +08:00
## Breaking Changes
## Performance Improvements
* Mission Control Store [improved performance during DB
flushing](https://github.com/lightningnetwork/lnd/pull/8549) stage.
# Technical and Architectural Updates
## BOLT Spec Updates
* Start assuming that all hops used during path-finding and route construction
[support the TLV onion
format](https://github.com/lightningnetwork/lnd/pull/8791).
* Allow channel fundee to send a [minimum confirmation depth of
0](https://github.com/lightningnetwork/lnd/pull/8796) for a non-zero-conf
channel. We will still wait for the channel to have at least one confirmation
and so the main change here is that we don't error out for such a case.
2024-05-14 15:39:09 +02:00
* [Groundwork](https://github.com/lightningnetwork/lnd/pull/8752) in preparation
for implementing route blinding receives.
2024-07-02 14:23:18 +02:00
* [Generate and send to](https://github.com/lightningnetwork/lnd/pull/8735) an
invoice with blinded paths. With this, the `--blind` flag can be used with
the `lncli addinvoice` command to instruct LND to include blinded paths in the
invoice.
2024-07-10 12:14:31 +02:00
* Add the ability to [send to use multiple blinded payment
paths](https://github.com/lightningnetwork/lnd/pull/8764) in an MP payment.
2024-08-05 14:39:44 +02:00
* [Improve route blinding invoice generation
UX](https://github.com/lightningnetwork/lnd/pull/8976) by making various
params configurable on a per-RPC basis.
2024-07-06 14:01:40 +08:00
## Testing
## Database
* [Migrate](https://github.com/lightningnetwork/lnd/pull/8855) incorrectly
stored invoice expiry values. This migration only affects users of native SQL
invoice database. Invoices with incorrect expiry values will be updated to
24-hour expiry, which is the default behavior in LND.
* [Fixed](https://github.com/lightningnetwork/lnd/pull/8854) pagination issues
in SQL invoicedb queries.
2024-08-01 16:54:21 +02:00
* [Check](https://github.com/lightningnetwork/lnd/pull/8938) leader status with
our health checker to correctly shut down LND if network partitioning occurs
towards the etcd cluster.
2024-07-06 14:01:40 +08:00
## Code Health
* [Move graph building and
maintaining](https://github.com/lightningnetwork/lnd/pull/8848) duties from
the `routing.ChannelRouter` to the new `graph.Builder` sub-system and also
remove the `channeldb.ChannelGraph` pointer from the `ChannelRouter`.
2024-07-06 14:01:40 +08:00
## Tooling and Documentation
2024-07-16 03:39:52 +08:00
* [`lntest.HarnessTest` no longer exposes `Miner`
instance](https://github.com/lightningnetwork/lnd/pull/8892). Instead, it's
changed into a private `miner` instance and all mining related assertions are
now only accessible via the harness.
