Cannot read property 'emit' of undefined

I'm getting the following error when using this plugin with webpack 3.11.0. When looking at the compiler source for v3.11.0 I don't see this.hooks.emit, but I do see it when looking at version v4.0.0.

Is this plugin only compatible with certain webpack versions? If so, can you update the docs with version compatibility info?

Thanks!

Ahh, now I'm seeing you have a section on webpack versions at the bottom of the page.
