title: Why does my symfony demo install with an old version of symfony?
body: <p>I installed the symfony demo but it installs using an older version, I'm not sure why? </p>
  
  <p>Earlier I installed an older version of the demo using command:</p>
  
  <pre><code>composer create-project symfony/symfony-demo bp3 1.1.1
  </code></pre>
  
  <p>This works fine and installs to directory bp3, runs fine, uses Symfony 3.3.9 (pops up a box in the bottom right on the Dev toolbar in red with the Symfony logo says sf 3.3.9 and when you hover says it is out of support).</p>
  
  <p>Then I tried to install the latest version of the demo using command:</p>
  
  <pre><code>symfony new bp4 --demo
  </code></pre>
  
  <p>I assumed it would install the latest version of the demo to directly bp4, but when I launch the site in directory bp4 it is running on Symfony 3.3.6. (pops up a box in the bottom right on the Dev toolbar in red with the Symfony logo says sf 3.3.6 and when you hover says it is out of support).</p>
  
  <ul>
  <li>Windows 10 Pro 64 bit</li>
  <li>Symfony CLI version v4.14.4</li>
  <li>Composer version 1.10.6 (installed globally)</li>
  <li>PHP 7.2.11 (cli)</li>
  </ul>
  
  <p>Thank you</p>
