AgileWiki is meant to create software systems which are fluid, easily configured and can be reorganized on-the-fly to meet ever changing requirements. It includes a COW-based database, the Rolonics programming paradigm, and semantic inferencing.
Multiple sessions are now supported. Numerous bugfixes have been made. Purge history is now working but remains incomplete.
