 With AIR, developers could access the file system (the user's files and folders), and connected devices such as a joystick, gamepad, and sensors for the first time.In 2011, "Adobe Flash Player 11" was released, and with it the first version of Stage3D, allowing GPU-accelerated 3D rendering for Flash applications and games on desktop platforms such as Microsoft Windows and Mac OS X. Adobe further improved 3D capabilities from 2011 to 2013, adding support for 3D rendering on Android and iOS platforms, alpha-channels, compressed textures, texture atlases, and other features.Adobe AIR was upgraded to support 64-bit computers, and to allow developers to add additional functionality to the AIR runtime using "AIR Native Extensions" (ANE).
