This conflict with the fact that you mention 1.3 above. FOSUserBundle dev-master is not 1.3 but 2.0.x-dev

And please don't advocate the ``dev-master`` requirement. As soon as a bundle provides a branch alias, it is better to use it rather than requiring dev-master. It will be safer if the bundle introduces a BC break in master (assuming they bump the branch alias properly of course).

So here, you should be requiring either ``1.3.*`` or ``2.0.*@dev``
