The release manager is TBD.  Please contact if you would like to participate in any way in preparing the ns-3.24 release.
'''Note:''' ns-3.24 was released on September 15; this page is left around for future reference.
* If you are interested in testing a particular feature that is planned for ns-3.24, see the section on this page for [[Ns-3.24#Testing_repos | testing repos]].
* If you are interested in helping with a code review of a specific feature that you'd like to see in ns-3.24, please leave your comments on the code review pertaining to the [[Ns-3.24#New_features | feature of interest]].
* If you are interested to see that a specific bug be fixed, please email ns-developers mailing list, or the release manager.  You will probably be asked to help with creating a patch or testing an existing patch for that bug, if so.

* A new feature release, [[ns-3.24]], is planned for September 15, 2015.
ns-3.24 is planned for August 2015; exact date TBD. ns-3 makes roughly three releases per year (Dec/Jan, Apr/May, and Aug/Sept timeframes).
** '''Release candidate available:''' As of September 14, a new (second) release candidate for [http://www.nsnam.org/release/ns-allinone-3.24.rc2.tar.bz2 ns-3.24] is available for testing.
 
This means that we ought to get most new features and major changes into the simulator by late July.
 
More detailed scheduling is TBD once the release date is set. In general:
* one or more release candidates will be posted in the week prior to the actual release
* new features should be merged several weeks in advance of the release date

This table is meant to put review items for merge to ns-3-dev on a schedule.  Maintainers of a module can commit changes as they see fit (i.e. without review for everything), but for proposals that seek or need a review, we should allow one to two weeks review time before the release manager or a maintainer commits the change.

Whether ns-3.24 is prepared in other packaging (e.g. Debian) would require a volunteer to prepare this.
Whether ns-3.24 will be distributed also as a [http://www.docker.com Docker container] would require a volunteer to prepare this.

We usually try to keep pace with the latest popular versions of Linux, OS X, and FreeBSD.  For the ns-3.24 release, we plan to support the following systems and compilers:
The latest OS X with Xcode, Fedora Linux, and Ubuntu Linux releases, along with some long term stable Linux releases such as CentOS 6.6 and Ubuntu 12.04/14.04.
 
TBD
 
= Testing repos =
 
Some repositories, based on a recent copy of ns-3-dev, will be available for testing specific features.
 
== Mobility Service Interface ==
 
Tiago Cerqueria has posted some code that uses Google Maps and Directions API to fetch waypoints for the ns-3 waypoint mobility model, corresponding to real-world routes provided by the service.  There is a testing repository available for this code (the patchset in https://codereview.appspot.com/176430044/ is too large to download from Rietveld).  To test, one must obtain an API key from Google, as described in the code review issue.  One must also have installed GeographicLib, xerces-cpp, libcurl, and libdl.
<pre>
hg clone http://code.nsnam.org/ns-3-dev
cd ns-3-dev/src
hg clone http://code.nsnam.org/tomh/mobility-service-interface
cd mobility-service-interface
mkdir conf
# copy your API key to this conf directory as described here https://codereview.appspot.com/176430044/
cd ../../
./waf configure ...

Developers are working or planning to work on the following new features for ns-3.24. 
 
'''Note:''' there is no guarantee that the features will be finished by the end of the release cycle, so check back for progress/status.
 
=== Energy Enhancements (Cristiano Tapparello) ===

This page summarizes the release planning for ns-3.24 (early September 2015). The ns-3 release process is listed here and here.

Note: ns-3.24 was released on September 15; this page is left around for future reference.

Release goals

1) Python 3 support for at least the basic waf and test.py operations; see the Python3 page.

2) continue the transition to a more modular build system. While a change away from the Waf build system is not planned for ns-3.24, one goal is to start to allow modules outside the core of ns-3 to be maintained in separate places, and integrated using the 'bake' tool (rather than merge everything into ns-3-dev).

  • A proposal can be found at ns-3.22-build Slipping to future release

3) finally try to implement Object Start/Stop; Vedran is working on a patch slipping to future release

4) Add new features as they become ready. In particular, finish inclusion of previous summer project code, including SOCIS 2013 and 2014 code (Bundle Protocol, TCP satellite extensions), Google Summer of Code (MLDv2, AQM queues FqCoDel and SfqCoDel), and 2014 mentored projects (Mobility Service Interface, and Python 3 support). slipping to future release

Release and development schedule

  • A new feature release, ns-3.24, is planned for September 15, 2015.
    • Release candidate available: As of September 14, a new (second) release candidate for ns-3.24 is available for testing.

Feature and patch review status

This table is meant to put review items for merge to ns-3-dev on a schedule. Maintainers of a module can commit changes as they see fit (i.e. without going through review for everything), but for proposals that seek or need a review, we should try to allow a default of 1 week review time before the release manager or a maintainer commits the change.

The following additional bug fixes will slip to next release:

Packaging

ns-3.24 will be packaged as a source tarball as before: ns-allinone-3.24.tar.bz2.

A patch from ns-3.23 to ns-3.24 will also be posted.
