Because people often work on whatever they feel like, only the current and current+1 releases should be taken seriously.  Beyond that is mainly conjectural.

THIS IS VERY OUTDATED

This is a working document showing specific near-term tasks needed for achieving the numbered milestones. It is not a wishlist of features to be included in future releases. Because people often work on whatever they feel like, only the current and current+1 releases should be taken seriously. Beyond that is mainly conjectural.

See OldRoadmap for milestones that have already been achieved.
