The Symfony2 Doctrine related Bundles move to the Doctrine organization. The DoctrineBundle being in the core for the 2.0 release it is now maintained in a more decoupled way from Symfony for several reasons:

• No coupling of release cycles anymore.
• Move code to the organization that actually maintains it.
• Avoid Symfony suggesting Doctrine is the only way for persistence, Symfony wants to focus on providing View and Controller and not make suggestions about the model.

The DoctrineFixturesBundle, DoctrineMigrationsBundle and DoctrineMongoDBBundle are now maintained in the Doctrine organization, however forks have been created in the Symfony repository to make all the 2.0 apps out there backwards compatible. You find the new repositories here:

• https://github.com/doctrine/DoctrineBundle
• https://github.com/doctrine/DoctrineMongoDBBundle
• https://github.com/doctrine/DoctrineFixturesBundle
• https://github.com/doctrine/DoctrineMigrationsBundle

What do you need to change in your code? Not very much. For the DoctrineBundle for example the following:

• Update the deps file to include the DoctrineBundle

  [empty]
  [DoctrineBundle]
      git=https://github.com/doctrine/DoctrineBundle.git
      target=/bundles/Doctrine/Bundle/DoctrineBundle

• Change the Bundle class

• Change references to Registry

The `SymfonyBundleDoctrineBundleRegistry` class may be type-hinted in your code. You have to change this code to point to `DoctrineBundleDoctrineBundleRegistry`.

A full deps file for all Doctrine bundles now looks like:

[empty]
[data-fixtures]
    git=https://github.com/doctrine/data-fixtures.git

[migrations]
    git=https://github.com/doctrine/migrations.git

[DoctrineBundle]
    git=https://github.com/doctrine/DoctrineBundle.git
    target=/bundles/Doctrine/Bundle/DoctrineBundle

[DoctrineMigrationsBundle]
    git=https://github.com/doctrine/DoctrineMigrationsBundle.git
    target=/bundles/Doctrine/Bundle/MigrationsBundle

[DoctrineFixturesBundle]
    git=https://github.com/doctrine/DoctrineFixturesBundle.git
    target=/bundles/Doctrine/Bundle/FixturesBundle

And the autoload.php:

$loader->registerNamespaces(array(
    'Symfony'          => array(__DIR__.'/../vendor/symfony/src', __DIR__.'/../vendor/bundles'),
    'Sensio'           => __DIR__.'/../vendor/bundles',
    'JMS'              => __DIR__.'/../vendor/bundles',
    'Doctrine\\Bundle' => __DIR__.'/../vendor/bundles',
    'Doctrine\\DBAL\\Migrations' => __DIR__.'/../vendor/migrations/lib',
    'Doctrine\\Common\\DataFixtures' => __DIR__.'/../vendor/data-fixtures/lib',
    'Doctrine\\Common' => __DIR__.'/../vendor/doctrine-common/lib',
    'Doctrine\\DBAL'   => __DIR__.'/../vendor/doctrine-dbal/lib',
    'Doctrine'         => __DIR__.'/../vendor/doctrine/lib',
    'Monolog'          => __DIR__.'/../vendor/monolog/src',
    'Assetic'          => __DIR__.'/../vendor/assetic/src',
    'Metadata'         => __DIR__.'/../vendor/metadata/src',
));

And the Kernel:

$bundles = array(
    new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
    new Symfony\Bundle\SecurityBundle\SecurityBundle(),
    new Symfony\Bundle\TwigBundle\TwigBundle(),
    new Symfony\Bundle\MonologBundle\MonologBundle(),
    new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
    new Symfony\Bundle\AsseticBundle\AsseticBundle(),
    new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
    new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
    new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
    new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
    new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle(),
);
