Thanks to everyone for contributing to this release, through pull requests, issues, and discussions!

This is a major release which contains breaking changes.

Key changes

• Enable batching on Mutations graphql-java/graphql-java#3737

• Support for draft error handling directive @experimental_disableErrorPropagation graphql-java/graphql-java#3772

• DataFetchers can now return reactive-streams Publisher objects from them and they will be turned into a CompleteableFuture value. Note only a single value will be retrieved from the Publisher graphql-java/graphql-java#3731

• We changed from JetBrains nullability annotations to JSpecify annotations graphql-java/graphql-java#3851. JSpecify is a new industry consortium effort, which has been adopted by Spring. See more in the documentation: https://jspecify.dev/docs/start-here/

• A new experimental callback is available to track the execution state of GraphQL Java: it allows for being notified when GraphQL Java is running actively code vs waiting/finished. See https://github.com/graphql-java/graphql-java/blob/master/src/test/groovy/graphql/EngineRunningTest.groovy#L174 for how to use it

• We have also released DataLoader 4.0.0 and made graphql-java dependent on it. See the release notes: https://github.com/graphql-java/java-dataloader/releases

• @defer directive is now included in the schema by default graphql-java/graphql-java#3839

Performance improvements

• Only call overlapping validation once during validation, which will significantly reduce validation time, with more savings for larger operations. We found ~150% improvement in benchmarks. graphql-java/graphql-java#3835

• Reducing object allocations and overhead from stream, thanks @​kilink for contributing many improvements graphql-java/graphql-java#3804 graphql-java/graphql-java#3803 graphql-java/graphql-java#3801 graphql-java/graphql-java#3798 graphql-java/graphql-java#3797 graphql-java/graphql-java#3710

• Reducing object allocations for PropertyDataFetcher and SchemaGeneratorHelper graphql-java/graphql-java#3755 graphql-java/graphql-java#3754

• Improvement on DataFetchingSelectionSet.getImmediateFields(), if descendant traversal is not required this saves considerable time. Thanks @​timward60 graphql-java/graphql-java#3855

• Comparing performance improvements. We run performance benchmarks on all changes, and you can view these results inside the GitHub repo. You can then use this JMH visualisation tool to compare benchmarks from different commits, for example these before and after results from the DataFetcherSelectionSet optimisation: https://jmh.morethan.io/?sources=https://raw.githubusercontent.com/graphql-java/graphql-java/refs/heads/master/performance-results/2025-03-18T23%3A42%3A07Z-3d7dce5e49dfbe92d656629ae4fdbab979bba8be-jdk17.json,https://raw.githubusercontent.com/graphql-java/graphql-java/refs/heads/master/performance-results/2025-03-20T04%3A24%3A26Z-9a931ba6ad8e2ee49ea48c98ca86c2901f2343b1-jdk17.json

Breaking changes

• Strict runtime wiring redefinition checks now on by default. We now have stricter runtime wiring redefinition checks by default to catch invalid cases. For example, a field that already had a DataFetcher registered must not have a second DataFetcher registered. This can be toggled off. graphql-java/graphql-java#3824

• Removed an unused protected method in ExecutionStrategy. graphql-java/graphql-java#3881

• A small breaking change to AstPrinter to enable re-use of StringBuilders graphql-java/graphql-java#3853
