UPGRADE FROM 2.2 to 2.3

When upgrading Symfony from 2.2 to 2.3, you need to do the following changes to the code that came from the Standard Edition:

• The debugging tools are not enabled by default anymore and should be added to the web/app_dev.php front controller manually, just after including the bootstrap cache:

   use Symfony\Component\Debug\Debug;
  
   Debug::enable();
  

  You also need to enable debugging in the app/console script, after the $debug variable is defined:

   use Symfony\Component\Debug\Debug;
  
   if ($debug) {
       Debug::enable();
   }
  

• The parameters.yml file can now be managed by the incenteev/composer-parameter-handler bundle that comes with the 2.3 Standard Edition:

  • add "incenteev/composer-parameter-handler": "~2.0" to your composer.json file;

  • add /app/config/parameters.yml to your .gitignore file;

  • create a app/config/parameters.yml.dist file with sensible values for all your parameters.

• It is highly recommended that you switch the minimum stability to stable in your composer.json file.

• If you are using Apache, have a look at the new .htaccess configuration and change yours accordingly.

• In the app/autoload.php file, the section about intl should be removed as it is not needed anymore.
