Description
As a user of graphql-js, I want to use the latest, stable and secure version of it. I will check the release notes and for the exemplary version 16, I'll find an incomprehensible list of 54 breaking changes, along another 43 notes. I won't understand these and continue to look for a Upgrade Guide which is currently not present.
Hereby, I suggest to create an Upgrade Guide for graphql-js, beginning at version 15 or 16, in order to facilitate the maintenance of graphql-js for its users.
