1.5.2.RELEASE
- RPC: add ServiceDescriptors to transcode RPC / Protocol Buffers calls into another representation (e.g. http/json).
- RPC compiler: generate ServiceDescriptors with "generate-service-descriptors" option - value format is "service_foo.proto;service_bar.proto", or empty to generate for all services. Descriptors are generated in server stubs for request-response interactions.
