When initializing a new component dependencies versions should be up-to-date

[eladav]

Now when you create a new component using dcm init it'll generate a package.json file with your dependencies set to some static version we hard-coded. In the process of creating the component dcm can check on npm and see what is the latest version that makes sense and initialize the component with that (i.e. there should be some strategy other than taking the latest but not something too complicated...)

See the code here. Instead of setting RN version to 52, we can now use 60. This can be done for every dependency in package.json files.
