On behalf of the Spring for GraphQL team, I am pleased to announce the availability of our first 1.4 milestone.

Aligning with the GraphQL over HTTP specification

The GraphQL over HTTP draft specification is making good progress, so we have decided to fully align with it for our 1.4 release. Previous versions of Spring for GraphQL already supported the official "application/graphql-response+json", and it has been our default response media type for a while now.

Usually, GraphQL HTTP clients should expect 4xx/5xx HTTP responses if the server is unavailable, security credentials are missing or if the request body is not valid JSON. The remaining gap with this new specification was about the HTTP response status behavior in case of complete GraphQL engine failures. With recent changes, "application/graphql-response+json" responses will also use 4xx statuses if the GraphQL document sent by the client cannot be parsed or is considered invalid by the GraphQL engine. We are keeping the former behavior when clients request the "application/json"…

On behalf of the team and everyone who has contributed, I am pleased to announce the second milestone of Spring Data 2025.0.0 ("Spring Data 3.5").

There are a few features we want to highlight for you to explore:

• Interface Projections using now are guarded properly throwing NullPointerException if a method return value is null (i.e. a getter method) although the method is defined to return a non-nullable value. This functionality is enabled for all Kotlin Interfaces. For all other interfaces, validation is enabled when the package or the interface is annotated with Nullability annotations and marked as non-null (or inherits @NonNullApi from the package level).
• Hash Field Expiration for Spring Data Redis, extended Expiration command support, and support for GET … SET.
• ValidatingEntityCallback and a reactive variant ReactiveValidatingEntityCallback…
