AVR Studio Beta is out and it's super awesome, go try it out. The file formats used by AVR Studio are different from AVR Studio (and older), and the AVR Studio related features inside AVR Project IDE are only relevant to AVR Studio and older.
This development environment is designed to provide an easy to use and lightweight editor that allows users to quickly program AVR microcontrollers. This editor combines easy project editing, configuration, building, and flash memory burning all into one environment.
