src/core/index.ts

Current

public createAssetTransferOutput(params: {
    recipient: AssetTransferAddress | string;
    assetType: H256 | string;
    amount: number;
}): AssetTransferOutput

Patch

public createAssetTransferOutput(params: {
    recipient: AssetTransferAddress | string;
    assetType: H256 | string;
    amount: number;
} | {
    lockScriptHash: H256 | string;
    parameters: Buffer[];
    assetType: H256 | string;
    amount: number;
}): AssetTransferOutput

The constructor of AssetTransferOutput already supports it.
