Docker-compose not upgraded automatically with Docker Engine?

I’m running Docker for Windows. By default, the service is set to automatically update my Docker engine and it does that fairly well. Currently running Docker Engine Version: 17.09.0-ce win33 (13620).

However, docker-compose is still only at version: 1.16.1. Yet I see that docker-compose has already released a version 1.17.0 and 1.17.1.

From what I understand, Docker for Windows is supposed to keep my docker-compose up to date as well, but it seems to be at least a couple of versions behind.

How do I go about updating docker-compose? Are only certain docker-compose versions bundled with the DockerEngine? If so, are those “bundled versions” listed anywhere? I couldn’t find any details on the Docker site.
