This is a brand new version of Dubbo 3, which includes REST, observability, GraalVM native image, and JDK17 support, etc... 🎉🎉🎉

Core Features

• Native REST protocol support(beta): Dubbo can now export or refer to a RESTful service using only Netty.
• Observability: Dubbo has introduced a series of metrics and tracing capabilities and supports various ways to report to third-party collectors.
• GraalVM native image support: You can now run Dubbo as a native image with dubbo-maven-plugin without any agents to pre-process.
• JDK17 and Spring Boot 3 support: Dubbo now officially supports JDK17 and Spring Boot 3.
• Performance improvements: For the Dubbo protocol, Dubbo 3.2 is up to 10 times faster than 3.1. For the Triple protocol, Dubbo 3.2 can perform comparably to gRPC-Java.
