## Next release
#### New Features
+- The loopd client reports off-chain routing failures for loop out swaps if
+ it cannot find a route to the server for the swap's prepay or invoice payment.
+ This allows the server to release accepted invoices, if there are any,
+ earlier, reducing the amount of time that funds are held off-chain. If the
+ swap failed on one of the loop server's channels, it will report failure
+ location of its off-chain failure. If the failure occurred outside of the
+ loop server's infrastructure, a generic failure will be used so that no
+ information about the client's position in the network is leaked.
