RPC --- - The `listdescriptors`, `decodepsbt` and similar RPC methods now show `h` rather than apostrophe (`'`) to indicate hardened derivation. This does not apply when using the `private` parameter, which matches the marker used when descriptor was generated or imported. Newly created wallets use `h`. This change makes it easier to handle descriptor strings manually. E.g. the `importdescriptors` RPC call is easiest to use `h` as the marker: `'["desc": ".../0h/..."]'`. With this change `listdescriptors` will use `h`, so you can copy-paste the result, without having to add escape characters or switch `'` to 'h' manually. Note that this changes the descriptor checksum. For legacy wallets the `hdkeypath` field in `getaddressinfo` is unchanged, nor is the serialization format of wallet dumps. (#26076)
