title: How to upgrade django?
body: <p>My project was running on Django 1.5.4 and I wanted to upgrade it. I did <code>pip install -U -I django</code> and now <code>pip freeze</code> shows Django 1.6.5 (clearly django has upgraded, I'm in <code>virtualenv</code>) but my project is still using Django 1.5.4. How can I use the upgraded version? </p>
  
  <p>UPDATE: Thanks for your comments. I tried everything but unfortunately nothing worked and I had to re-deploy the app.</p>
  
  <p>Hope someone explains why this happened.</p>
