+RPC changes
+-----------
+- The `walletcreatefundedpsbt` RPC call will now fail with
+ `Insufficient funds` when inputs are manually selected but are not enough to cover
+ the outputs and fee. Additional inputs can automatically be added through the
+ new `add_inputs` option.
+
+- The `fundrawtransaction` RPC now supports `add_inputs` option that when `false`
+ prevents adding more inputs if necessary and consequently the RPC fails.
