 As of now, dbus-next targets the latest features of JavaScript. The earliest version supported is `6.3.0`. However, the library uses `BigInt` by default for the long integer types which was introduced in `10.8.0`. If you need to support versions earlier than this, set BigInt compatibility mode. This will configure the library to use [JSBI](https://github.com/GoogleChromeLabs/jsbi) as a polyfill for long types.

 ## The Service Interface

-You can use the `Interface` class to define your interfaces. This interfaces uses the proposed [decorators syntax](https://github.com/tc39/proposal-decorators) which is not yet part of the ECMAScript standard, but should be included one day. Unfortunately, you'll need a [Babel plugin](https://www.npmjs.com/package/@babel/plugin-proposal-decorators) to make this code work for now.

 The low-level interface can be used to interact with messages directly. Create new messages with the `Message` class to be sent on the bus as method calls, signals, method returns, or errors. Method calls can be called with the `call()` method of the `MessageBus` to await a reply and `send()` can be use for messages that don't expect a reply.
