This minor version release includes:
- Change the default behavior of Loop Out swaps to use the new Loop Out delay
--fastflag to execute Loop Out swaps immediately
- Add delay configuration to the Loop Out client API
The new delay option is related to an on-going effort to minimize the on-chain footprint of Lightning Loop, which will deliver increased privacy and lower chain fees.
If multiple execution delayed Loop Outs are present at the time of Loop Out on-chain funding, the Loop service will now batch those funding outputs together into a single transaction, reducing the number of change outputs and required inputs used for each swap.
