The ns-3.4 Release

This page summarizes the ongoing release planning for the Fourth stable release of ns-3.

The Release Manager

The release manager is Raj Bhattacharjea.

The ns-3.4 Release Schedule

ns-3 releases are based on date-driven schedules as opposed to feature-driven schedules. We decide on an approximate release date and then the release manager works backward to define windows during which time certain activites related to the release can happen. This was done for ns-3.3 and the important milestones for that release can be found here.

This is an approximate schedule, and is subject to change.

  1. December 17, 2008 -- ns-3.4 Open phase begins.
  2. January 20 -- Recommended cutoff for new feature submission;
  3. January 27 -- Deadline for new feature submissions that require design review;
  4. February 3 -- Approved new feature ready-for-merge deadline;
  5. February 3 -- Late merge period begins (Merge Week Begins);
  6. February 25 -- Late merge period ends;
  7. February 25 -- Open phase ends;
  8. February 25 -- Maintenance phase begins;
  9. March 18 -- Maintenance phase ends;
  10. March 18 -- Code freeze phase begins;
  11. March 20 -- ns-3.4-RC1;
  12. March 23 -- ns-3.4-RC2;
  13. March 27 -- ns-3.4-RC3;
  14. March 31 -- ns-3.4-RC4;
  15. April 1 -- ns-3.4 posted;
  16. April 1 -- Code freeze phase ends;
  17. April 1 -- ns-3.5 Open phase begins.

Candidates for Merge into ns-3.4

As you can see in the Roadmap, we have identified several candidates for inclusion in ns-3.4. As time passes and details become more evident, more status regarding the progress of these new features will be added.
