Bundle not compatible with doctrine/orm 2.4.2

[Sinjonathan]

I can't install the bundle with the require :
"symfony/symfony": "~2.4",
"doctrine/orm": "~2.2,>=2.2.3",
"sonata-project/doctrine-orm-admin-bundle": "dev-master"

It works with the require :
"symfony/symfony": "~2.4",
"doctrine/orm": "2.3.5",
"sonata-project/doctrine-orm-admin-bundle": "~2.1"
