title: Showing Deprecation Warnings Only for a Specific Version When Testing Django
body: <p>I am about to upgrade from Django 1.9 to 1.10 and would like to test if I have some deprecated functionality.</p>
  
  <p>However using</p>
  
  <pre><code>python -Wall manage.py test
  </code></pre>
  
  <p>will show tons and tons of warnings for Django 2.0. Is there a way to suppress warnings only for 2.0 or show only warnings for 1.10?</p>
