PI's are fundamental for designing and maintaining quality components. Eclipse currently has little tooling to support the design, implementation and maintenance of APIs. As part of the Ganymede release, PDE provides tools to support binary compatibility checking, API usage scanning and plug-in version numbering management. This talk details the technology available in Ganymede, supported usecases and outlines directions for future development. We will also discuss the challenges of proper version management in the bundle world.
