title: Updating package with Bower
body: <p>I am trying to update angular 1.0.5 to 1.0.6. I use Yeoman, and when try to update it is installing 1.0.5. I cleared the cache (removed everything from ~/.bower), still get the below log. I checked the <a href="https://github.com/angular/bower-angular/blob/master/angular.js" rel="noreferrer">repo</a>, and it has 1.0.6. Is there a way I can make it update to 1.0.6.</p>
  
  <pre><code>bower update angular
  bower cloning git://github.com/angular/bower-angular.git
  ..
  bower installing angular#v1.0.5
  
  bower info angular
  angular
