+> ### Notice
+> We are currently working hard on redesigning and refactoring this project with high quality and robustness in mind. As a result, issues and pull requests will take more time to process. 
+
+> To avoid any confusion and breaking existing projects, all continuous development is published under the npm tag `next`, with version `2.0.0-experimental.x`. Once stable, we will publish it as `2.0.0`. **This version supports react-native `0.31.0`**.
+
+> The last stable version is `1.30.x` with npm tag `latest`. **This version supports react-native `0.25.1`**.
