v3.2.0-rc1

Features

• Introduce brand new programming API.
• Upgraded triple protocol, 100% compatible with gRPC while supporting direct HTTP API access with application/json payload.
• RPC service definition supports both IDL and NON-IDL.
• Observability enhancement, metrics & tracing
• Introduce weighted round-robin and alias-method load-balance strategies

Interoperability With Java

This version guarantees fully interoperability between dubbo go and java implementations, below are some interop examples:

• Example demonstrating dubbo + hesian interop
• Example demonstrating triple + protobuf interop
• Example demonstrating triple + non-protobuf interop
• Example demonstrating service discovery interop

Compatibility

This version is completely compatible with 3.0.x ~ 3.1.x versions. Users using old API and triple protocol can upgrade to this version directly without changing any code.

v3.1.0

Breaking Changes

For users upgrading from 3.0.x or below, please notice that the default service discovery model in 3.1.0 has changed to registry-type: instance, which stands for the application-level discovery model in Dubbo3.

To be able to discover instances of lower version, please set registry-type of 3.1.0 instance to interface in via dubbogo.yml or API:

dubbo:
  registries:
     zk: 
       protocol: zookeeper
       address: 127.0.0.1:2181
       registry-type: interface

Features

• Implement RemoveConfig API for nacos and zookeeper
• Expose TLSConfig for config api
• Add subscribe any value
• Implement condition routing basic functions and complete related tests
• Implement dynamic routing
• Tag route static config
• Upgrade nacos 2.x
• Print logs of registered providers and consumers
• Add request processing total and request succeed total metrics
• Add some metrics about RT
• Add metrics base api interface
• Sliding window and rt quantile metrics
