Release Name: DQL - I love you 3000 
Changelog
- User can view & edit DQL schema directly from the app under the schema page, no need to launch Ratel for it.
- User can view all DQL predicates generated by the GraphQL mode to better understand how Dgraph creates predicates for given GraphQL schema and leverage DQL.
- Backend modes have been renamed to Schema mode with a better definition for each mode. The default mode is strict only allowing mutations on predicates already present in the schema. Read more about schema modes
