# Release Notes
|
|
|
|
## Peer to Peer Protocol
|
|
|
|
Scripts received as part of an upfront shutdown script [are now properly
|
|
sanitized](https://github.com/lightningnetwork/lnd/pull/5369) to ensure
|
|
widespread relay of potential cooperative channel closures.
|
|
|
|
## Wallet Unlocking
|
|
|
|
[A new flag has been added](https://github.com/lightningnetwork/lnd/pull/5457)
|
|
to permit users to set the new password file config while at the same time,
|
|
allowing `lnd` to start up and accept new wallet initialization/creation via the
|
|
RPC interface. The new wallet-unlock-allow-create option instructs lnd to not
|
|
fail if no wallet exists yet but instead spin up its unlocker RPC as it would
|
|
without the wallet-unlock-password-file being present. This is not recommended
|
|
for auto-provisioned or high-security systems because the wallet creation RPC
|
|
is unauthenticated and an attacker could inject a seed while lnd is in that
|
|
state.
|
|
|
|
## RPC Server
|
|
|
|
[The `Shutdown` command will now return an
|
|
error](https://github.com/lightningnetwork/lnd/pull/5364) if one attempts to
|
|
call the command while `lnd` is rescanning.
|
|
|
|
New clients connecting/disconnecting to the transaction subscription stream
|
|
[are now logged](https://github.com/lightningnetwork/lnd/pull/5358).
|
|
|
|
[The `MinConfs` param is now properly examined if the `SendAll` param is
|
|
set](https://github.com/lightningnetwork/lnd/pull/5200) for the `SendCoins` RPC
|
|
call.
|
|
|
|
[The `abandonchannel` RPC call can now be used without the `dev` build
|
|
tag](https://github.com/lightningnetwork/lnd/pull/5335). A new flag
|
|
`--i_know_what_i_am_doing` must be specified when using the call without the
|
|
`dev` build tag active.
|
|
|
|
## Integration Test Improvements
|
|
|
|
[A bug has been fixed in the `testChannelForceClosure`
|
|
test](https://github.com/lightningnetwork/lnd/pull/5348) that would cause the
|
|
test to assert the wrong balance (the miner fee wasn't accounted for).
|
|
|
|
## Forwarding Optimizations
|
|
|
|
[Decoding onion blobs is now done in
|
|
parallel](https://github.com/lightningnetwork/lnd/pull/5248) when decoding the
|
|
routing information for several HTLCs as once.
|
|
|
|
## Build System
|
|
|
|
The [`monitoring` build tag is now on by
|
|
default](https://github.com/lightningnetwork/lnd/pull/5399) for all routine
|
|
builds.
|
|
|
|
## Deadline Aware in Anchor Sweeping
|
|
|
|
Anchor sweeping is now [deadline
|
|
aware](https://github.com/lightningnetwork/lnd/pull/5148). Previously, all
|
|
anchor sweepings use a default conf target of 6, which is likely to cause
|
|
overpaying miner fees since the CLTV values of the HTLCs are far in the future.
|
|
Brought by this update, the anchor sweeping (particularly local force close)
|
|
will construct a deadline from its set of HTLCs, and use it as the conf target
|
|
when estimating miner fees. The previous default conf target 6 is now changed
|
|
to 144, and it's only used when there are no eligible HTLCs for deadline
|
|
construction.
|
|
|
|
## Bug Fixes
|
|
|
|
An optimization intended to speed up the payment critical path by
|
|
eliminating an extra RPC call [has been
|
|
reverted](https://github.com/lightningnetwork/lnd/pull/5404) as it
|
|
introduced a regression that would cause payment failure due to mismatching
|
|
heights.
|
|
|
|
[A bug has been fixed that would previously cause any HTLCs settled using the
|
|
`HltcInteceptor` API calls to always be re-forwarded on start
|
|
up](https://github.com/lightningnetwork/lnd/pull/5280).
|
|
|
|
[A bug has been fixed in the parameter parsing for the `lncli` PSBT funding
|
|
call](https://github.com/lightningnetwork/lnd/pull/5441). Prior to this bug
|
|
fix, the sat/vb param was ignored due to a default value for `conf_target`.
|
|
|
|
[A bug has been fixed that would prevent nodes that had anchor channels opening
|
|
from accepting any new inbound "legacy"
|
|
channels](https://github.com/lightningnetwork/lnd/pull/5428).
|
|
|
|
[A bug has been fixed cause an `lncli` command to fail with on opaque error
|
|
when the referenced TLS cert file doesn't
|
|
exist](https://github.com/lightningnetwork/lnd/pull/5416).
|
|
|
|
[When `lnd` receives an HTLC failure message sourced from a private channel,
|
|
we'll now properly apply the update to the internal hop hints using during path
|
|
finding](https://github.com/lightningnetwork/lnd/pull/5332).
|
|
|
|
[A regression has been fixed that caused `keysend` payments on the "legacy" RPC
|
|
server to fail due to newly added AMP
|
|
logic](https://github.com/lightningnetwork/lnd/pull/5419).
