Has the definition of value type changed between federation 1 and federation 2?

[ki-ri]

Hi! I noticed that the definition of Value Type has changed between federation 1 and federation 2, am I correct?

• for federation 1: https://www.apollographql.com/docs/federation/v1/value-types
• for federation 2: Value Types in Apollo Federation - Apollo GraphQL Docs
• 

In Federation 2, it appears that the only recognized ‘type’ is the value type, whereas in Federation 1, types such as Scalars, Objects, Interfaces, Inputs, Enums, and Unions were also considered value types.

Hello

Value types are just a name of a concept of sharing same types across different subgraphs. Federation 2 supports sharing of all GraphQL types. It expands on Federation 1 validation rules and relaxes some of the constraints there.
