Is the Improved API for nested mutations (
https://github.com/graphcool/graphcool/issues/1280) implemented in the RC1? It should exists since beta1!?
I want to upsert the relation (create new/update existing) . But in my Playground i have only the options connect or create inside the nested object. The docs say there are the operations: create, update, delete, upsert, connect, disconnect
