title: How to replace deprecated uib-datepicker-popup?
body: <p>Since I updated my project to <code>"angular-bootstrap": "~1.2.4"</code>, I've a warning in the console:</p>
  
  <p><code>uib-datepicker settings via uib-datepicker-popup attributes are deprecated and will be removed in UI Bootstrap 1.3, use datepicker-options attribute instead</code></p>
  
  <p><code>uib-datepicker-popup</code> is filled by a date format or an array of date formats:</p>
  
  <ul>
  <li><code>uib-datepicker-popup="dd-MMMM-yyyy"</code> in my case</li>
  </ul>
  
  <p>So in <a href="https://angular-ui.github.io/bootstrap/#datepicker" rel="nofollow noreferrer">angular bootstrap documentation</a> it is still shown the <code>deprecated</code> way to handle this case.</p>
  
  <p>Does anyone know how to migrate to the new version?</p>
