Android Studio 1.3

<li> The Setup Wizard now longer installs the Android M preview by default; it installs the most recent stable version (currently API 22). You should only install and use the Android M preview (and buildtools 23-rc) if you are also going to use version 1.3.0-beta1 of the Android Gradle plugin. </li> <li> The layout editor and layout preview windows only use the Android M preview layout library if the project is compiled with the M preview library.
