  • February 18th, 2009: A separate release of JTella has been made available for download on our sourceforge page. The main interest is that the implementation is fully documented, which can be useful for a developer who wants to reuse or modify this part.
  • January 28th, 2009: UP2P v2.0.3 released with some major bug fixes. JTella seems to be working quite well, and the ditrect file uploads work. Likely the last release before introduction of the tuple-space architecture.

    Coming soon: a developer’s guide for the refactored source code!
  • September 11th, 2008: release of U-P2P v2.0 alpha (binary).
    This version has reverted to the old functionalities of U-P2P (support of multiple communities without cross-community searches), but a number of problems have been fixed, and the general architecture of U-P2P has been overhauled to serve as basis for the future integration of a tuple-space core.
  • May 2008: after some big construction the refreshed UP2P is wobbly on its legs. The different parts of the applications are decoupled.
  • Summer 2007: we start a plan to refactor the application to allow further research and development.
  • 2006: a prototype of the system works, based on a web application architecture, rebuilt by Neal Arthorne. A paper is published at CASCON’06 based on this new prototype.
    All functional parts of the application are heavily coupled and the beast is difficult to modify.
  • 2002: the first version of UP2P sees the light, created by Alokhe Mukherjee and Babak Esfandiari
