+New RPCs
+--------
+
+- The `sendall` RPC spends specific UTXOs to one or more recipients
+  without creating change. By default, the `sendall` RPC will spend
+  every UTXO in the wallet. `sendall` is useful to empty wallets or to
+  create a changeless payment from select UTXOs. When creating a payment
+  from a specific amount for which the recipient incurs the transaction
+  fee, continue to use the `subtractfeefromamount` option via the
+  `send`, `sendtoaddress`, or `sendmany` RPCs. (#24118)
