title: When I run webpack --version, I see 1.14.0 even when I know I installed the latest
body: <p>I am returning to a project using webpack and updating my npm modules.  When I update webpack to use the latest version using the command <code>npm install webpack@latest</code>, checking the version with the command <code>webpack --version</code> I see 1.14.0.  Is that correct?  I thought it should be like 4x or something.</p>
