Use Doctrine 2.4 with Symfony and composer.json - php

Question

Doctrine 2.4 has some interesting new features that I'd like to use in my current Symfony 2.3 project.
Is there a composer.json configuration to use doctrine 2.4 with Symfony? I can’t find a valid dependency list. If I specify the 2.4.3 version of doctrine/orm in my composer.json I get a composer update error because doctrine/doctrine-bundle does not allow a doctrine install > 2.3.
Doctrine 2.4 is mentioned in the Symfony2 docs but I haven't found a valid composer.json list.
Any help is appreciated.
Current composer.json

composer.json:
"require": {
"php": ">=5.3.3",
"symfony/symfony": "2.3.*",
"doctrine/orm": "2.4.*",
"doctrine/doctrine-bundle": "~1.2",
....
Then update your dependencys
$ composer update doctrine\orm
But ! im not sure, if it is supported because the symfony master is using the same version since 2.3 (symfony 2.5 composer.json)
"require": {
"doctrine/orm": "~2.2,>=2.2.3",
"doctrine/doctrine-bundle": "~1.2",
