This commit bumps LND and lndclient to make it possible to upgrade
taproot HTLC construction with a MuSig2 version. This is required to
support both old (MuSig2 0.4) and new (MuSig2 1.0) clients.
In this commit we bump the minimum LND version required to run loopd to
v0.15.1-beta in order to ensure that the underlying chain backend
supports taproot (https://github.com/lightningnetwork/lnd/pull/6798)
Our preimage push test previously relied on our dropping down to the
default sweep conf target to mock a drop in chain fees. This makes
our test dependent on height, which makes changes to our sweep logic
regarding when we reveal our preimage break this test. In this commit
that logic is replaced with simply locking our mock and updating fees
on the fly.
We update to the latest lndclient that now requires a label when
publishing an on-chain transaction. Instead of just adding an empty
string, we use the proper labels added in a previous commit.
Projects that use a later version of lnd than loop, but also depend on
loop itself would run into the following build error:
