 For this library version, and for all future 1.x versions, the callback-based API will be the default, and the promises-based variant will need to be explicitly selected, to avoid breaking backwards compatibility. However, a move to the promises-based variant as the default is possible at the next major release. If you are not handling promises, and want a version of the library that will not start returning promises for calls where you don't pass a callback in future versions, you can explicitly require the callback variant.
