# Release Notes
|
|
|
|
## DB
|
|
|
|
* Split channeldb [`UpdateInvoice`
|
|
implementation](https://github.com/lightningnetwork/lnd/pull/7377) logic in
|
|
different update types.
|
|
|
|
* Add [invoice SQL schema and
|
|
queries](https://github.com/lightningnetwork/lnd/pull/7354)
|
|
|
|
* Add new [sqldb
|
|
package](https://github.com/lightningnetwork/lnd/pull/7343)
|
|
|
|
## Watchtowers
|
|
|
|
* Let the task pipeline [only carry
|
|
wtdb.BackupIDs](https://github.com/lightningnetwork/lnd/pull/7623) instead of
|
|
the entire retribution struct. This reduces the amount of data that needs to
|
|
be held in memory.
|
|
|
|
* [Replace in-mem task pipeline with a disk-overflow
|
|
queue](https://github.com/lightningnetwork/lnd/pull/7380)
|
|
* [Replay pending and un-acked updates onto the main task pipeline if a tower
|
|
is being removed](https://github.com/lightningnetwork/lnd/pull/6895)
|
|
|
|
* [Add defaults](https://github.com/lightningnetwork/lnd/pull/7771) to the
|
|
wtclient and watchtower config structs and use these to populate the defaults
|
|
of the main LND config struct so that the defaults appear in the `lnd --help`
|
|
command output.
|
|
|
|
* The deprecated "wtclient.private-tower-uris" option has also been
|
|
[removed](https://github.com/lightningnetwork/lnd/pull/7771). This field was
|
|
deprecated in v0.8.0-beta.
|
|
|
|
## Misc
|
|
|
|
* [Ensure that both the byte and string form of a TXID is populated in the
|
|
lnrpc.Outpoint message](https://github.com/lightningnetwork/lnd/pull/7624).
|
|
|
|
* [Fix Benchmark Test (BenchmarkReadMessage/Channel_Ready) in the lnwire
|
|
package](https://github.com/lightningnetwork/lnd/pull/7356)
|
|
|
|
* [Fix unit test flake (TestLightningWallet) in the neutrino package via
|
|
version bump of btcsuite/btcwallet](https://github.com/lightningnetwork/lnd/pull/7049)
|
|
|
|
* [HTLC serialization updated](https://github.com/lightningnetwork/lnd/pull/7710)
|
|
to allow storing extra data transmitted in TLVs.
|
|
|
|
* [MaxLocalCSVDelay now has a default value of 2016. It is still possible to
|
|
override this value with the config option --maxlocaldelay for those who rely
|
|
on the old value of 10000](https://github.com/lightningnetwork/lnd/pull/7780).
|
|
|
|
## RPC
|
|
|
|
* [SendOutputs](https://github.com/lightningnetwork/lnd/pull/7631) now adheres
|
|
to the anchor channel reserve requirement.
|
|
|
|
* Enforce provided [fee rate is no less than the relay or minimum mempool
|
|
fee](https://github.com/lightningnetwork/lnd/pull/7645) when calling
|
|
`OpenChannel`, `CloseChannel`, `SendCoins`, and `SendMany`.
|
|
|
|
* The [UpdateNodeAnnouncement](https://github.com/lightningnetwork/lnd/pull/7568)
|
|
API can no longer be used to set/unset protocol features that are defined by
|
|
LND.
|
|
|
|
* [Neutrinorpc getblockhash has
|
|
been deprecated](https://github.com/lightningnetwork/lnd/pull/7712). Endpoint
|
|
has been moved to the chainrpc sub-server.
|
|
|
|
Custom node announcement feature bits can also be specified in config using
|
|
the `dev` build tag and `--protocol.custom-nodeann`, `--protocol.custom-init`
|
|
and `--protocol.custom-invoice` flags to set feature bits for various feature
|
|
"sets", as defined in [BOLT 9](https://github.com/lightning/bolts/blob/master/09-features.md).
|
|
|
|
* `OpenChannel` now accepts an [optional `memo`
|
|
argument](https://github.com/lightningnetwork/lnd/pull/7668) for specifying
|
|
a helpful note-to-self containing arbitrary useful information about the
|
|
channel.
|
|
|
|
* `PendingOpenChannel` now has the field
|
|
[`funding_expiry_blocks`](https://github.com/lightningnetwork/lnd/pull/7480)
|
|
that indicates the number of blocks until the funding transaction is
|
|
considered expired.
|
|
|
|
* [gRPC keepalive parameters can now be set in the
|
|
configuration](https://github.com/lightningnetwork/lnd/pull/7730). The `lnd`
|
|
configuration settings `grpc.server-ping-time` and `grpc.server-ping-timeout`
|
|
configure how often `lnd` pings its clients and how long a pong response is
|
|
allowed to take. The default values for there settings are improved over the
|
|
gRPC protocol internal default values, so most users won't need to change
|
|
those. The `grpc.client-ping-min-wait` setting defines how often a client is
|
|
allowed to ping `lnd` to check for connection healthiness. The `lnd` default
|
|
value of 5 seconds is much lower than the previously used protocol internal
|
|
value, which means clients can now check connection health more often. For
|
|
this to be activated on the client side, gRPC clients are encouraged to set
|
|
the keepalive setting on their end as well (using the `grpc.keepalive_time_ms`
|
|
option in JavaScript or Python, or the equivalent setting in the gRPC library
|
|
they are using, might be an environment variable or a different syntax
|
|
depending on the programming language used) when creating long open streams
|
|
over a network topology that might silently fail connections. A value of
|
|
`grpc.keepalive_time_ms=5100` is recommended on the client side (adding 100ms
|
|
to account for slightly different clock speeds).
|
|
|
|
* [Fixed a bug where we didn't check for correct networks when submitting
|
|
onchain transactions](https://github.com/lightningnetwork/lnd/pull/6448).
|
|
|
|
* [Fix non-deterministic behaviour in RPC calls for
|
|
custom accounts](https://github.com/lightningnetwork/lnd/pull/7565).
|
|
In theory, it should be only one custom account with a given name. However,
|
|
due to a lack of check, users could have created custom accounts with various
|
|
key scopes. The non-deterministic behaviours linked to this case are fixed,
|
|
and users can no longer create two custom accounts with the same name.
|
|
|
|
* `OpenChannel` adds a new `utxo` flag that allows the specification of multiple
|
|
UTXOs [as a basis for funding a channel
|
|
opening.](https://github.com/lightningnetwork/lnd/pull/7516)
|
|
|
|
* The [BatchOpenChannel](https://github.com/lightningnetwork/lnd/pull/7820)
|
|
message now supports all fields that are present in the `OpenChannel` message,
|
|
except for the `funding_shim` and `fundmax` fields.
|
|
|
|
* The [WalletBalance](https://github.com/lightningnetwork/lnd/pull/7857) RPC
|
|
(lncli walletbalance) now supports showing the balance for a specific account.
|
|
|
|
## Misc
|
|
|
|
* [Generate default macaroons
|
|
independently](https://github.com/lightningnetwork/lnd/pull/7592) on wallet
|
|
unlock or create.
|
|
|
|
* [Restore support](https://github.com/lightningnetwork/lnd/pull/7678) for
|
|
`PKCS8`-encoded cert private keys.
|
|
|
|
* Add [`--unused`](https://github.com/lightningnetwork/lnd/pull/6387) to
|
|
`lncli newaddr` command.
|
|
|
|
* [Cleanup](https://github.com/lightningnetwork/lnd/pull/7770) of defaults
|
|
mentioned in [sample-lnd.conf](https://github.com/lightningnetwork/lnd/blob/master/sample-lnd.conf).
|
|
It is possible to distinguish between defaults and examples now.
|
|
A check script has been developed and integrated into the building process to
|
|
compare the default values between lnd and sample-lnd.conf.
|
|
|
|
* [Cancel rebroadcasting of a transaction when abandoning
|
|
a channel](https://github.com/lightningnetwork/lnd/pull/7819)
|
|
|
|
## Code Health
|
|
|
|
* Updated [our fork for serializing protobuf as JSON to be based on the
|
|
latest version of `google.golang.org/protobuf` instead of the deprecated
|
|
`github.com/golang/protobuf/jsonpb`
|
|
module](https://github.com/lightningnetwork/lnd/pull/7659).
|
|
|
|
## Neutrino
|
|
|
|
* The [Neutrino version
|
|
is updated](https://github.com/lightningnetwork/lnd/pull/7788) so that LND can
|
|
take advantage of the latest filter fetching performance improvements.
|
|
|
|
## Testing
|
|
|
|
* [Started](https://github.com/lightningnetwork/lnd/pull/7494) running fuzz
|
|
tests in CI.
|
|
|
|
* [Derandomized](https://github.com/lightningnetwork/lnd/pull/7618) the BOLT
|
|
8 fuzz tests.
|
|
|
|
* [Improved](https://github.com/lightningnetwork/lnd/pull/7723) invoice fuzz
|
|
tests.
|
|
|
|
* [Added fuzz tests](https://github.com/lightningnetwork/lnd/pull/7649) for
|
|
signature parsing and conversion.
|
|
|
|
* [Added a fuzz test](https://github.com/lightningnetwork/lnd/pull/7687) for
|
|
watchtower address iterators.
|
|
|
|
* [Simplify fuzz tests](https://github.com/lightningnetwork/lnd/pull/7709)
|
|
using the `require` package.
|
|
|
|
* [Removed](https://github.com/lightningnetwork/lnd/pull/7854) need for an
|
|
active internet connection for the network connection itest.
|
|
|
|
## `lncli`
|
|
|
|
* Added ability to use [ENV variables to override `lncli` global flags](https://github.com/lightningnetwork/lnd/pull/7693). Flags will have preference over ENVs.
|
|
|
|
* The `lncli sendcoins` command now asks for manual confirmation when invoked
|
|
on the command line. This can be skipped by adding the `--force` (or `-f`)
|
|
flag, similar to how `lncli payinvoice` works. To not break any existing
|
|
scripts the confirmation is also skipped if `stdout` is not a terminal/tty
|
|
(e.g. when capturing the output in a shell script variable or piping the
|
|
output to another program).
|
|
|
|
## Bug Fix
|
|
|
|
* Make sure payment stream returns all the events by [subscribing it before
|
|
sending](https://github.com/lightningnetwork/lnd/pull/7722).
|
|
|
|
* Fixed a memory leak found in mempool management handled by
|
|
[`btcwallet`](https://github.com/lightningnetwork/lnd/pull/7767).
|
|
|
|
* Make sure lnd starts up as normal in case a transaction does not meet min
|
|
mempool fee requirements. [Handle min mempool fee backend error when a
|
|
transaction fails to be broadcasted by the
|
|
bitcoind backend](https://github.com/lightningnetwork/lnd/pull/7746)
|
|
|
|
* [Updated bbolt to v1.3.7](https://github.com/lightningnetwork/lnd/pull/7796)
|
|
in order to address mmap issues affecting certain older iPhone devices.
|
|
|
|
* [Stop rejecting payments that overpay or over-timelock the final hop](https://github.com/lightningnetwork/lnd/pull/7768)
|
|
|
|
* [Fix let's encrypt autocert generation](https://github.com/lightningnetwork/lnd/pull/7739)
|
|
|
|
* Fix an issue where [IPv6 couldn't be dialed when using
|
|
Tor](https://github.com/lightningnetwork/lnd/pull/7783), even when
|
|
`tor.skip-proxy-for-clearnet-targets=true` was set.
|
|
|
|
* Fix a [concurrency issue related to rapid peer teardown and
|
|
creation](https://github.com/lightningnetwork/lnd/pull/7856) that can arise
|
|
under rare scenarios.
|
|
|
|
- A race condition found between `channel_ready` and link updates is [now
|
|
fixed](https://github.com/lightningnetwork/lnd/pull/7518).
|
|
|
|
### Tooling and documentation
|
|
|
|
* Add support for [custom `RPCHOST` and
|
|
`RPCCRTPATH`](https://github.com/lightningnetwork/lnd/pull/7429) to the
|
|
`lnd` Docker image main script (`/start-lnd.sh`).
|
|
|
|
* Fix bug in `scripts/verify-install.sh` that caused the [release binary
|
|
signature verification script to not properly import signing
|
|
keys](https://github.com/lightningnetwork/lnd/pull/7758) when being run with
|
|
new version of `gpg` (which is the case in the latest Docker image).
