### Low-level changes

- The `getwalletinfo` RPC method now returns an `hdseedid` value, which is always the same as the incorrectly-named `hdmasterkeyid` value. `hdmasterkeyid` will be removed in V0.18.
- The `getaddressinfo` RPC method now returns an `hdseedid` value, which is always the same as the incorrectly-named `hdmasterkeyid` value. `hdmasterkeyid` will be removed in V0.18.

Other API changes
