title: How to update CodeIgniter with Composer?
body: <p>I switched from Symfony to CodeIgniter and I would like it to stay up-to-date with the framework.</p>
  <p>I understand that you can easely install and update all kind of packages, I know how to do it as I did it over and over again with Symfony.</p>
  <p>I already set <code>$config['composer_autoload'] = TRUE;</code> in <code>application/config/config.php</code>. (Thanks to a lot of other SO questions)</p>
  <p>My problem: Composer seems to update all the packages fine, but not the framework itself. Is it possible or am I doomed to do it manually?</p>
  <h1>EDIT</h1>
  <p>Please consider using CodeIgniter 4, which is made to be used with Composer from the start. CodeIgniter 3 is old and should only be used on legacy projects.</p>
