Callisto

Callisto is about improving the productivity of the developers working on top of Eclipse frameworks by providing a more transparent and predictable development cycle. By releasing 10 projects at the same time in 2006, the goal is to eliminate uncertainty about version compatibility and make it easier to incorporate multiple projects into your environment. While Callisto is about the simultaneous release of ten projects, it is not a unification of the projects - each project remains a separate open source project operating with its own project leadership, its own committers, and its own project plan.
