Release 1.4.0: JSON:API Compound Documents Plugin.

[MoonWorm]

This release introduces support for JSON:API Compound Documents.

The feature is implemented as a pluggable module — simply add the dependency:

<dependency>
      <groupId>pro.api4</groupId>
      <artifactId>jsonapi4j-cd-plugin</artifactId>
      <version>1.4.0</version>
</dependency>

and configure how related resources are resolved and fetched via your application configuration.

JSON:API's compound documents let you fetch a resource and all its related data in one request, eliminating extra round-trips and keeping everything perfectly consistent. It's a powerful way to deliver rich, interconnected data graphs efficiently - like getting an entire object tree in a single, clean response.

The Compound Documents resolver is also available as a separate lightweight module with virtually no third-party dependencies. It can be used outside of JsonApi4j services - for example, at the API Gateway layer, where compound document resolution may be handled in certain architectures:

<dependency>
      <groupId>pro.api4</groupId>
      <artifactId>jsonapi4j-compound-docs-resolver</artifactId>
      <version>1.4.0</version>
</dependency>
