UPDATED:Google serves Donuts to Android developers
Romain Guy, an Android team member, has cleared up some of the earlier information regarding Google's distribution of Donut to developers. Mr. Guy says that Donut is not Android OS 2.0. This is basically the same thing that happened with Cupcake which is not officially OS build 1.5 even though most of the improvements in 1.5 were from the Cupcake code branch. Guy also wanted to point out that despite earlier hints and reports, multi-touch support is not included in the upgrade.
