# Bug Fixes
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/8857) to correctly
|
|
propagate mission control and debug level config values to the main LND config
|
|
struct so that the GetDebugInfo response is accurate.
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/9033) where we
|
|
would not signal an error when trying to bump a non-anchor channel but
|
|
instead report a successful cpfp registration although no fee bumping is
|
|
possible for non-anchor channels anyways.
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/9269) where a
|
|
negative fee limit for `SendPaymentV2` would lead to omitting the fee limit
|
|
check.
|
|
|
|
* [Use the required route blinding
|
|
feature-bit](https://github.com/lightningnetwork/lnd/pull/9143) for invoices
|
|
containing blinded paths.
|
|
|
|
* [Fix a bug](https://github.com/lightningnetwork/lnd/pull/9137) that prevented
|
|
a graceful shutdown of LND during the main chain backend sync check in certain
|
|
cases.
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/9068) where dust
|
|
htlcs although not being able to be resolved onchain were not canceled
|
|
back before the commitment tx was confirmed causing potentially force closes
|
|
of the incoming channel.
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/9249) found in the
|
|
mission control store that can block the shutdown process of LND.
|
|
|
|
* Make sure the RPC clients used to access the chain backend are [properly
|
|
shutdown](https://github.com/lightningnetwork/lnd/pull/9261).
|
|
|
|
* [Fixed a bug](https://github.com/lightningnetwork/lnd/pull/9275) where the
|
|
peer may block the shutdown process of lnd.
|
|
|
|
* [Fixed a case](https://github.com/lightningnetwork/lnd/pull/9258) where the
|
|
confirmation notification may be missed.
|
|
|
|
* [Make the contract resolutions for the channel arbitrator optional](
|
|
https://github.com/lightningnetwork/lnd/pull/9253)
|
|
|
|
# New Features
|
|
## Functional Enhancements
|
|
## RPC Additions
|
|
|
|
* [Add a new rpc endpoint](https://github.com/lightningnetwork/lnd/pull/8843)
|
|
`BumpForceCloseFee` which moves the functionality soley available in the
|
|
`lncli` to LND hence making it more universal.
|
|
|
|
* [The `walletrpc.FundPsbt` RPC method now has an option to specify the fee as
|
|
`sat_per_kw` which allows for more precise
|
|
fees](https://github.com/lightningnetwork/lnd/pull/9013).
|
|
|
|
* [The `walletrpc.FundPsbt` method now has a new option to specify the maximum
|
|
fee to output amounts ratio.](https://github.com/lightningnetwork/lnd/pull/8600)
|
|
|
|
## lncli Additions
|
|
|
|
* [A pre-generated macaroon root key can now be specified in `lncli create` and
|
|
`lncli createwatchonly`](https://github.com/lightningnetwork/lnd/pull/9172) to
|
|
allow for deterministic macaroon generation.
|
|
|
|
* [The `lncli wallet fundpsbt` sub command now has a `--sat_per_kw` flag to
|
|
specify more precise fee
|
|
rates](https://github.com/lightningnetwork/lnd/pull/9013).
|
|
|
|
* The `lncli wallet fundpsbt` command now has a [`--max_fee_ratio` argument to
|
|
specify the max fees to output amounts ratio.](https://github.com/lightningnetwork/lnd/pull/8600)
|
|
|
|
# Improvements
|
|
## Functional Updates
|
|
|
|
* [Allow](https://github.com/lightningnetwork/lnd/pull/9017) the compression of
|
|
logs during rotation with ZSTD via the `logging.file.compressor` startup
|
|
argument.
|
|
|
|
* The SCB file now [contains more data][https://github.com/lightningnetwork/lnd/pull/8183]
|
|
that enable a last resort rescue for certain cases where the peer is no longer
|
|
around.
|
|
|
|
* LND updates channel.backup file at shutdown time.
|
|
|
|
## RPC Updates
|
|
|
|
* Some RPCs that previously just returned an empty response message now at least
|
|
return [a short status
|
|
message](https://github.com/lightningnetwork/lnd/pull/7762) to help command
|
|
line users to better understand that the command was executed successfully and
|
|
something was executed or initiated to run in the background. The following
|
|
CLI commands now don't just return an empty response (`{}`) anymore:
|
|
* `lncli wallet releaseoutput` (`WalletKit.ReleaseOutput` RPC)
|
|
* `lncli wallet accounts import-pubkey` (`WalletKit.ImportPublicKey` RPC)
|
|
* `lncli wallet labeltx` (`WalletKit.LabelTransaction` RPC)
|
|
* `lncli sendcustom` (`Lightning.SendCustomMessage` RPC)
|
|
* `lncli connect` (`Lightning.ConnectPeer` RPC)
|
|
* `lncli disconnect` (`Lightning.DisconnectPeer` RPC)
|
|
* `lncli stop` (`Lightning.Stop` RPC)
|
|
* `lncli deletepayments` (`Lightning.DeleteAllPaymentsResponse` RPC)
|
|
* `lncli abandonchannel` (`Lightning.AbandonChannel` RPC)
|
|
* `lncli restorechanbackup` (`Lightning.RestoreChannelBackups` RPC)
|
|
* `lncli verifychanbackup` (`Lightning.VerifyChanBackup` RPC)
|
|
* The `ForwardInterceptor`'s `MODIFY` option will
|
|
[merge](https://github.com/lightningnetwork/lnd/pull/9240) any custom
|
|
range TLVs provided with the existing set of records on the HTLC,
|
|
overwriting any conflicting values with those supplied by the API.
|
|
|
|
## lncli Updates
|
|
|
|
## Code Health
|
|
|
|
* [Add retry logic](https://github.com/lightningnetwork/lnd/pull/8381) for
|
|
watchtower block fetching with a max number of attempts and exponential
|
|
back-off.
|
|
|
|
* [Moved](https://github.com/lightningnetwork/lnd/pull/9138) profile related
|
|
config settings to its own dedicated group. The old ones still work but will
|
|
be removed in a future release.
|
|
|
|
* [Update to use structured
|
|
logging](https://github.com/lightningnetwork/lnd/pull/9083). This also
|
|
introduces a new `--logging.console.disable` option to disable logs being
|
|
written to stdout and a new `--logging.file.disable` option to disable writing
|
|
logs to the standard log file. It also adds `--logging.console.no-timestamps`
|
|
and `--logging.file.no-timestamps` which can be used to omit timestamps in
|
|
log messages for the respective loggers. The new `--logging.console.call-site`
|
|
and `--logging.file.call-site` options can be used to include the call-site of
|
|
a log line. The options for this include "off" (default), "short" (source file
|
|
name and line number) and "long" (full path to source file and line number).
|
|
Finally, the new `--logging.console.style` option can be used under the `dev`
|
|
build tag to add styling to console logging.
|
|
|
|
* [Add max files and max file size](https://github.com/lightningnetwork/lnd/pull/9233)
|
|
options to the `logging` config namespace under new `--logging.file.max-files`
|
|
and `--logging.files.max-file-size` options. The old options (`--maxlogfiles`
|
|
and `--maxlogfilesize`) will still work but deprecation notices have been
|
|
added and they will be removed in a future release. The defaults values for
|
|
these options have also been increased from max 3 log files to 10 and from
|
|
max 10 MB to 20 MB.
|
|
|
|
* [Deprecate `dust-threshold`
|
|
config option](https://github.com/lightningnetwork/lnd/pull/9182) and introduce
|
|
a new option `channel-max-fee-exposure` which is unambiguous in its description.
|
|
The underlying functionality between those two options remain the same.
|
|
|
|
## Breaking Changes
|
|
## Performance Improvements
|
|
|
|
* Log rotation can now use ZSTD
|
|
|
|
# Technical and Architectural Updates
|
|
## BOLT Spec Updates
|
|
|
|
* Add new [lnwire](https://github.com/lightningnetwork/lnd/pull/8044) messages
|
|
for the Gossip 1.75 protocol.
|
|
|
|
## Testing
|
|
## Database
|
|
|
|
* [Migrate the mission control
|
|
store](https://github.com/lightningnetwork/lnd/pull/8911) to use a more
|
|
minimal encoding for payment attempt routes as well as use [pure TLV
|
|
encoding](https://github.com/lightningnetwork/lnd/pull/9167).
|
|
|
|
* [Migrate the mission control
|
|
store](https://github.com/lightningnetwork/lnd/pull/9001) so that results are
|
|
namespaced. All existing results are written to the "default" namespace.
|
|
|
|
## Code Health
|
|
|
|
## Tooling and Documentation
|
|
|
|
* [Improved `lncli create` command help text](https://github.com/lightningnetwork/lnd/pull/9077)
|
|
by replacing the word `argument` with `input` in the command description,
|
|
clarifying that the command requires interactive inputs rather than arguments.
