we are now releasing version 2.0.1 which is a maintenance release which primarily fixes issues with the toolchain and project migration issues (from 1.0), and updated UC3 Software Frameworks.
The 2.0.1 installers will be available on atmel.com soon. Those with 2.0 already installed should use the update manager to upgrade. Unless you turned it off, the automatic update should do this for you when you start AVR32 Studio the next time. The release notes are included in the Help (the Welcome page is a nice place to start), please do read the upgrade instructions and known issues.
