Software companies have a tendency to give sounding codenames to upcoming releases; For e.g. Ubuntu Linux, gives each major operating system update an adjective/animal name such as "Hardy Heron," "Intrepid Ibex," and "Jaunty Jackalope." Google decided to name all its Android OS updates after desserts. Hence the name of Android 1.5, which was known as Cupcake. According to Google's Andy Rubin, the next three updates for Android will be Donut, Eclair and Flan. Rubin didn't provide any details about when these operating system updates will become available, nor what new features will be included.
