dubbo-3.3.0-beta.1

We are very excited to announce the first beta release of the 3.3.x branch, a release that has some very exciting features to reveal.

It is highly recommended to stay on 3.2.x for production usage and only upgrade to 3.3.x after the first stable release is available (with no beta suffix).

New Features

• New Triple protocol, fully compatible with gRPC while supporting direct access from cURL and browser.
• Rest-style programming (Spring MVC and JAX-RS) and communication (application/json) support, much easier for Dubbo application to serve as a standard web server.
• A bunch of starters for easy dependency management when developing with Spring Boot (Zookeeper, Nacos, Sentinel, etc.).
• GraalVM Native Image support with Dubbo AOT.
• Fully JDK 21 support and project loom thread model.
• Metrics and tracing improvement.
