title: How to set package latest version in Bower?
body: <p>I was watching this <a href="http://www.youtube.com/watch?v=USk1ie30z5k" rel="noreferrer">nice video</a> about requirejs, backbone and bower and something does not work for me. How can I set latest version of package in <em>bower.json</em> file? In video Jeff says that <em>null</em> should be used to define latest version like this </p>
  
  <pre><code>{
      "name": "project name",
      "version": "1.0.0",
      "dependencies": {
          "backbone-amd": null,
          "underscore-amd": null,
          "requirejs": null
      }
  }
  </code></pre>
  
  <p>But I have an exception in console that I can't use <em>null</em> value as version number. I couldn't find any info at bower wiki. Does anybody know how to solve this? </p>
