v14.2.0

Behaviour changes

• Generic superclasses (#825, fixes #460 and #218): type variables are now resolved against the most specific class. Methods inherited from a generic superclass keep their resolved type arguments, so two subclasses that bind them differently (e.g. Page<A> and Page<B>) can no longer share one GraphQL type. Schema parsing fails with "Two different classes used for type" in that case.
• Plain futures (#839, fixes #203): a resolver that returns a Future graphql-java can't wait on (anything that isn't a CompletionStage, e.g. a FutureTask or RxJava's toFuture()) now fails the field with an error that says what to return instead. Before, the future itself reached graphql-java as the field value.
• Generic wrapper results (#836, fixes #371): a generic wrapper transformer that returns null now resolves the field to null instead of falling back to the wrapper object.
• Suspend resolvers (#831, fixes #419): they now start undispatched and run on the calling thread until their first suspension, so DataLoader loads are queued before graphql-java dispatches them.
• Directive wirings (#830, #834): several wirings on the same element now chain, each one starting from the previous one's output. Applied directives now include arguments that have a default value in the directive definition.

Deprecations

• Passing a CoroutineScope as the context object is deprecated and logs a warning. Put it in the GraphQLContext under the CoroutineScope class key instead. Support for the context object will be removed in the next major release.
• getDirective(), getDirectives() and getDirective(name) on SchemaDirectiveWiringEnvironmentImpl are deprecated in favour of getAppliedDirective(), getAppliedDirectives() and getAppliedDirective(name).
