# Release Notes
2021-10-04 09:33:12 +02:00
## Payments
Support according to the
[spec ](https://github.com/lightningnetwork/lightning-rfc/pull/912 ) has been
added for [payment metadata in
invoices](https://github.com/lightningnetwork/lnd/pull/5810). If metadata is
present in the invoice, it is encoded as a tlv record for the receiver.
This functionality unlocks future features such as [stateless
invoices](https://lists.linuxfoundation.org/pipermail/lightning-dev/2021-September/003236.html).
2021-09-11 14:43:46 +02:00
## Security
* [Misconfigured ZMQ
setup now gets reported](https://github.com/lightningnetwork/lnd/pull/5710).
2022-03-24 14:51:46 +01:00
## Taproot
The internal on-chain wallet of `lnd` is now able to create and spend from
[Taproot (SegWit v1)
addresses](https://github.com/lightningnetwork/lnd/pull/6263). Using
`lncli newaddress p2tr` will create a new BIP-0086 keyspend only address and
then watch it on chain. Taproot script spends are also supported through the
`signrpc.SignOutputRaw` RPC (`/v2/signer/signraw` in REST).
2022-04-27 22:20:39 +02:00
## MuSig2
The [`signrpc.Signer` RPC service now supports EXPERIMENTAL MuSig2
signing](https://github.com/lightningnetwork/lnd/pull/6361).
More information can be found in the [MuSig2 documentation ](../musig2.md ).
Note that the MuSig2 BIP is not final yet and therefore the MuSig2 API must be
considered to be HIGHLY EXPERIMENTAL and subject to change in upcoming
releases. Backward compatibility is not guaranteed!
2021-12-09 11:36:47 +01:00

* Add [auto-generated command-line completions ](https://github.com/lightningnetwork/lnd/pull/4177 )
for Fish shell.
2022-01-12 17:38:53 +01:00

2022-01-17 17:11:27 +01:00
* Add [private status ](https://github.com/lightningnetwork/lnd/pull/6167 )
to pendingchannels response.
2022-02-04 14:31:15 +01:00

to allow for RPC calls via Tor.
2021-12-04 09:17:54 +01:00
## Bug Fixes
2022-02-09 19:39:42 +01:00
* [Pipelining an UpdateFulfillHTLC message now only happens when the related UpdateAddHTLC is locked-in. ](https://github.com/lightningnetwork/lnd/pull/6246 )
2021-12-04 09:17:54 +01:00
* [Fixed an inactive invoice subscription not removed from invoice
registry](https://github.com/lightningnetwork/lnd/pull/6053). When an invoice
subscription is created and canceled immediately, it could be left uncleaned
due to the cancel signal is processed before the creation. It is now properly
handled by moving creation before deletion.
2021-12-04 09:25:39 +01:00
* When the block height+delta specified by a network message is greater than
the gossiper's best height, it will be considered as premature and ignored.
[These premature messages are now saved into a cache and processed once the
height has reached.](https://github.com/lightningnetwork/lnd/pull/6054)
2022-02-07 08:07:10 +01:00
* [Fixed failure to limit our number of hop hints in private invoices ](https://github.com/lightningnetwork/lnd/pull/6236 ).
When a private invoice is created, and the node had > 20 (our hop hint limit)
private channels with inbound > invoice amount, hop hint selection would add
too many hop hints. When a node had many channels meeting this criteria, it
could result in an "invoice too large" error when creating invoices. Hints
are now properly limited to our maximum of 20.
2022-01-30 05:14:37 +01:00
* [Fixed an edge case where the lnd might be stuck at starting due to channel
arbitrator relying on htlcswitch to be started
first](https://github.com/lightningnetwork/lnd/pull/6214).
2022-03-08 07:35:44 +01:00
* [Added signature length
validation](https://github.com/lightningnetwork/lnd/pull/6314) when calling
`NewSigFromRawSignature` .
2022-03-14 10:18:52 +01:00
* [Fixed deadlock in invoice
registry](https://github.com/lightningnetwork/lnd/pull/6332).

party sweeps our anchor
output](https://github.com/lightningnetwork/lnd/pull/6274).

* [Fixed a bug that would cause lnd to be unable to parse certain PSBT blobs ](https://github.com/lightningnetwork/lnd/pull/6383 ).
2022-03-28 12:47:23 +02:00
* [Use normal TCP resolution, instead of Tor DNS resolution, for addresses
using the all-interfaces IP](https://github.com/lightningnetwork/lnd/pull/6376).
2022-03-30 03:08:32 +02:00
2022-03-29 18:11:39 +02:00

`golangci-lint` in your `$GOPATH/bin` directory. `make lint` does not
automatically replace it with the new version if the binary already exists!
