 ## 特性
 - 支持excel族、json、xml、lua、yaml 多种数据格式，基本统一了游戏常见的配置数据
-- **强大完备的类型系统**。**可以优雅表达任意复杂的数据结构**。支持所有常见原生类型、datetime类型、容器类型list,set,map、枚举和结构、**多态结构**以及**可空类型**。
+- **强大完备的类型系统**。**可以优雅表达任意复杂的数据结构**。支持所有常见原生类型、text本地化类型、datetime类型、vector{2,3,4}、容器类型list,set,map、枚举和结构、**多态结构**以及**可空类型**。
 - 支持增强的excel格式。可以在excel里比较简洁填写出任意复杂的嵌套数据。
 - 生成代码清晰易读、良好模块化。支持指定变量命名风格约定。特地支持运行时原子性热更新配置。
 - 灵活的数据源定义。一个表可以来自多个文件或者一个文件内定义多个表或者一个目录下所有文件甚至来自云表格，以及以上的组合
 - 支持表与字段级别分组。可以灵活定义分组，选择性地导出客户端或者服务器或编辑器所用的表及字段
-- 多种导出数据格式支持。支持binary、json、**protobuf**、lua、xml、erlang、**xlsx** 及自定义的导出数据格式
-- 支持xlsx与json、lua、protobuf等格式之间互转
+- 支持生成**protobuf**、**msgpack**、**flatbuffers**相应的定义文件及相应的数据文件（直接反射导出，高效，并不需要生成代码后再利用生成的代码加载导出）
+- 多种导出数据格式支持。支持binary、json、**protobuf**、**msgpack**、**flatbuffers**、lua、xml、erlang、**xlsx** 及自定义的导出数据格式
+- 支持xlsx与json、lua、xml、yaml等格式之间互转
 - 强大灵活的定制能力
 	- 支持代码模板，可以用自定义模板定制生成的代码格式
 	- **支持数据模板**，可以用模板文件定制导出格式。意味着可以在不改动现有程序代码的情况下，把luban当作**配置处理前端**，生成自定义格式的数据与自己项目的配置加载代码配合工作。开发已久的项目或者已经上线的老项目，也能从luban强大的数据处理工作流中获益
