title: App engine default Django version change
body: <p>Since app engine 1.4.2 was released, I am getting warnings like this in my production logs:</p>
  
  <blockquote>
    <p>You are using the default Django
    version (0.96). The default Django
    version will change in an App Engine
    release in the near future. Please
    call use_library() to explicitly
    select a Django version. For more
    information see
    <a href="http://code.google.com/appengine/docs/python/tools/libraries.html#Django" rel="noreferrer">http://code.google.com/appengine/docs/python/tools/libraries.html#Django</a></p>
  </blockquote>
  
  <p>This occurs on every handler where I use a Django template - via the following:</p>
  
  <pre><code>from google.appengine.ext.webapp import template
  </code></pre>
  
  <p>I'd like to upgrade to 1.2, however the following links don't seem very clear on exactly how to do this (or whether it works at all):</p>
  
  <ul>
  <li><a href="http://code.google.com/appengine/docs/python/tools/libraries.html#Django" rel="noreferrer">http://code.google.com/appengine/docs/python/tools/libraries.html#Django</a></li>

  <li><a href="http://code.google.com/p/googleappengine/issues/detail?id=4489" rel="noreferrer">http://code.google.com/p/googleappengine/issues/detail?id=4489</a></li>

  </ul>
  
  <p>The common thread is to insert this:</p>
  
  <pre><code>from google.appengine.dist import use_library
  use_library('django', '1.2')
  </code></pre>
  
  <p>However, in what file(s) should this be inserted:</p>
  
  <ol>
  <li>Just in appengine_config.py?</li>
  <li>In every .py file which does <code>from google.appengine.ext.webapp import template</code>?</li>
  <li>In every .py file in the project?</li>
  <li>In 1 and (2 or 3) above, and also add <code>import appengine_config</code> to those files?</li>
  <li>In 3 or 4, and also add wrappers around built-in functions like appstats, remote api, datastore admin, etc?</li>
  <li>Something else?</li>
  </ol>
  
  <p>Thanks.</p>
