Overview

v1.10.0 brings graphql-go up to the official GraphQL September 2025 spec, including support for the new @oneOf directive and validation behavior brought into much closer parity with graphql-js. It also ships a round of validation and lexer optimizations plus a number of bug fixes, especially around introspection, deprecations, subscriptions, and default values.
