@andimarek andimarek released this Jan 17, 2020 · 44 commits to master since this release


This is a big release after more than 6 months without a new major version. It consists of over 70 PRs which is mainly smaller bugfixes and improvements from all over the place.

The "biggest" feature in terms of work was the new SchemaTransformer and FieldVisibilitySchemaTransformation: it allows you to transform a GraphQLSchema and more specifically to remove one or more fields from a GraphQLSchema. While implementing this we refactored the GraphQLType hierarchy. If you are doing advanced GraphQLSchema processing you might be affected by it.

The most impactful changes for normal users are probably:

  • The ID scalar was changed to serialize all objects (#1693)
  • There is a new java.util.Locale available on the DataFetcherEnvironment set when you start executing a query (#1576)
  • Support of all unicode characters (#1603)
  • add getArgumentOrDefault to DataFetcherEnvironment (#1659)
  • Correctly support additional optional arguments in fields defined by interfaces (#1694)
  • add hook to allow for custom value unboxing (#1684)

But the impact really depends on your specific use, so please have a look at the complete list below.

Breaking changes

#1685: We changed the default behaviour for the local context property: It is now null by default on top
level fields.

#1605 and other: We refined the type system for GraphQLSchema objects (classes implementing GraphQLType) and introduced a general SchemaTransformer class which lets you transform a GraphQLSchema object.

#1734: The SDL PostProcessor hook was renamed from SchemaTransformer to SchemaGeneratorPostProcessing to make the purpose more clear but also to make the name SchemaTransformer available.
