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;
