This release includes a new option to specify the sweep confirmation target for Loop Out.
This will delay the finality of the swap in favor of a potential reduction in chain fee expenditure.
If you are using this feature, please note that it does become increasingly important that you do not allow
loopd to terminate before the swap is final, otherwise the timeout pathway may activate in the HTLC.
Because of the finality problem, the target will only be used at the start of the swap preimage reveal time period and is not a guaranteed final sweep fee rate.
