 - `pair.sign(message)` now takes an optional second `options?: SignOptions` parameter, where `SignOptions` is currently defined as `{ withType: boolean }`. Here `withType` instructs the signing to prepend the type of signature (ed2551, sr25519 or ecdsa). This is used for the new Polkadot/Substrate MultiSignature format.
