The first beta is out!

Important changes:

1. The base module (graphql) provides the plugin system and API. Most of the shipped functionality has been consolidated into the graphql_core module.
2. Configuring the schema with entity view modes has been deprecated and moved out of the codebase. The graphql_legacy project is there to maintain backwards compatibility and should provide a smooth path for upgrading an existing project.
3. Therefore, upon enabling graphql_core, the schema will expose all content entities, while respecting all of Drupal's access restriction mechanisms.
4. Entity mutations have been deprecated (for now) in favour of writing dedicated plugins that will do the job better. Again, graphql_legacy is there to maintain compatibility.
5. Some of the more experimental features have been moved to dedicated repositories:
   • Views support
   • JSON parsing
   • XML parsing
   • GraphQL + Twig
