将Doctrine 2.4与Symfony和composer.json一起使用

Doctrine 2.4有一些有趣的新功能，我想在我目前的Symfony 2.3项目中使用它 .

是否有一个composer.json配置使用与Symfony的doctrine 2.4？我找不到有效的依赖列表 . 如果我在composer.json中指定了doctrine / orm的2.4.3版本，我会得到一个作曲家更新错误，因为doctrine / doctrine-bundle不允许doctrine install> 2.3 .

Symfony2文档中提到了Doctrine 2.4，但我没有找到有效的composer.json列表 .

任何帮助表示赞赏 .

当前的composer.json
