This page summarizes the ongoing release planning for ns-3.9. Josh Pelkey and Tom Henderson are acting release managers.

Tentative Release Schedule

  1. May 3 -- ns-3.8 posted; ns-3.9 Open phase begins
  2. June 16 -- Deadline for proposing major new features to be merged; begin the phase of small feature development and bug fixing
  3. June 25 -- Deadline for merge of major features identified on the release page
  4. July 20 -- Small feature development and bug fixing ends; Maintenance phase begins
  5. August 6 -- Maintenance phase ends, code freeze phase begins; only P1 critical blockers and documentation

beyond this date

  1. August 11 -- First release candidate (ns-3.9 RC1)
  2. August 16 -- Documentation and code freeze (manuals/tutorials/Doxygen) (ns-3.9 RC2)

Features that may slip

The following features are slipping to ns-3.10 or later:

  • VANET mobility model (no reviews)
  • TCP Vegas (blocked by lack of progress on TCP congestion control architecture)
  • Chord/DHT (authors are planning to revise code based on comments)
  • app store and build system refactoring
  • remove ./waf --regression
