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.

Inkscape 0.92 ~ Infrastructure Focus

Inkscape 1.0

  • Strict bugfix focus, with all development targeted to feature branches
  • This will be a long term stable release series

Following is a WIP draft of the post-1.0 release goals; this is not yet finalized, and should not be taken as official yet
