Protocol Buffers 3.0 发布,该版本与上一个稳定版 2.6.1 版本比较,主要改进包括: 全面的 3.0 协议版本 proto3: 废弃 optional 关键字 Removed non-zero default values and field presence logic for non-message fields. Group fields are no longer supported in proto3 syntax. Changed
repeated primitive fields to use packed serialization by default in
proto3 (implemented for C++, Java, Python in this release). Added well-known type protos (any.proto, empty.proto, timestamp.proto, duration.proto, etc.). Proto3 JSON is supported in several languages (fully supported in C++, Java, Python and C# partially supported in Ruby). Proto3 enforces strict UTF-8 checking.
