The document summarizes Nokia X platform 2.0, which provides an improved user experience over version 1.0. It is now compatible with Android 4.3 instead of 4.1. While the API offering remains mainly the same, ensuring compatibility of applications from version 1.0, there are new features like a control panel and ongoing tasks layer. The user interface also includes enhancements like a 4-column layout and separation of applications, widgets, and notifications.
