The following represents a rough feature roadmap for Google App Engine. At Google we've historically avoided giving release dates for our products because we know that software development is incredibly hard to predict. Thus, it should be noted that while we're working hard on these features, development schedules do slip at times, and the dates below may change. We'll do our best to update this roadmap as our engineers continue development.

Future Releases: October 2008 - March 2009

• Service for storing and serving large files
