 # Release Notes
 
+## Remote signing
+
+The [remote signing](../remote-signing.md) setup was simplified in that the
+signing node now [does not need to be hooked up to its own chain
+backend](https://github.com/lightningnetwork/lnd/pull/6006). A new mock chain
+backend can be specified with `--bitcoin.node=nochainbackend`. That way a wallet
+will be created and all signing RPCs work but the node will not look at any
+chain data. It can therefore be fully offline except for a single incoming gRPC
+connection from the watch-only node.
