I'm not a composer expert, and perhaps I don't understand some things about it.
There is new Symfony CMF version I wanted to use for learning it: https://github.com/symfony-cmf/symfony-cmf/blob/master/composer.json
As you see in composer.json, there is requirement to use:
"symfony-cmf/core-bundle": "1.1.*",
In routing-auto-bundle https://github.com/symfony-cmf/RoutingAutoBundle/blob/master/composer.json :
"symfony-cmf/core-bundle": "1.0.*",
Does this difference stops me from using routing-auto-bundle? Or I can do something somehow with this? As mentioned, I'm still learning of composer.
