JSON-RPC --- For RPC methods which accept `options` parameters ((`importmulti`, `listunspent`, `fundrawtransaction`, `bumpfee`, `send`, `sendall`, `walletcreatefundedpsbt`, `simulaterawtransaction`), it is now possible to pass the options as named parameters without the need for a nested object. (#26485) This means it is possible make calls like: ```sh src/bitcoin-cli -named bumpfee txid fee_rate=100 ``` instead of ```sh src/bitcoin-cli -named bumpfee txid options='{"fee_rate": 100}' ```
