The new version of Neo4j GraphQL Java (1.3 and 1.4) introduces several exciting features, including integration with Spring-Boot DGS applications, allowing for the combination of schema augmentation and DGS's feature set. The library now supports type-safe APIs, better pagination, and alignment with neo4j/graphql.js. Additionally, default values for paging and sorting can be defined in the source schema, making it easier to query the API in a type-safe manner. The library also aligns its API with the official JavaScript version, with features such as using scalars for temporal types, separate sorting and paging into own input types, and improved testing capabilities.
