I am currently using Auth0 Integration + GC Console and was planning to upgrade to CLI to use the auth templates for social sign in. Will these templates be affected significantly by the 1.0 update or should I wait?

I think it's prudent to wait. GraphCool 1.0 is just the database layer, leaving the server implementation to you. You can see how they did authentication in their demo app https://github.com/graphql-cli/graphql-boilerplate/tree/master/node-basic

OK Yah I am thinking it may make the transition easier by holding back
