v0.23.1
When react-native init sets up a new project and installs the react package, it will use the version specified in the peerDependencies section of React Native's package.json file. Previously, it would always install the latest version of React, rather than the latest compatible version. This change makes sure that React Native will continue using React 0.14.x when React 15.0.0 is released.
If you already have an existing React Native project, you do not need to upgrade from 0.23.0 to 0.23.1.
