This page summarizes the release planning for ns-3.26 (originally planned for June 2016; rescheduled to early September 2016). The ns-3 release process is listed here and here.

This page has been recently revised and some original goals for ns-3.26 have slipped to a new ns-3.27 page.

Revised schedule

The revised (again) schedule is as follows:

  • code freeze once outstanding issues resolved
  • release shortly afterwards

Please test the Release Candidate 1 posted on 27 September, and provide feedback to ns-developers mailing list or the bug tracker.
