Google has posted an early access release of Android 1.5, Cupcake. According to Xavier Ducrohet, "This new version (which will be 1.5) is based on the cupcake branch from the Android Open Source Project. Version 1.5 introduces APIs for features such as soft keyboards, home screen widgets, live folders, and speech recognition."
