Welcome to AppScale 2.0!

We are happy to announce the release of AppScale 2.0! The theme for this release is better, stronger, faster, and the bump in the major number reflects the depth of the changes. Like all major releases, a reload of the application and the data will need to occur, so please take a backup before upgrading to 2.0.
