Hi All, I like this awesome template too. i have use it in my project before, it's simple and straightforward.

recently I've setup a new repo based on the new React version (16.x).
https://github.com/zhuang17/react-material-admin

all the related lib & tools (material-ui, react-router, rechart, and dev-tools script) has been updated as well. please feel free to give a try.

following are some main changes.

• react-router -> react-router-dom v4
• react 14.x -> 16.x
• webpack, babel -> react-script
• material 0.18.x -> 3.2.x
• rechart 0.20.8 -> 1.3.4
