Release and development schedule

ns-3.23 was planned for Wednesday May 6 2015 but is likely to be released in the May 13 timeframe.

ns-3 makes roughly three releases per year (Dec/Jan, Apr/May, and Aug/Sept timeframes).


ns-3.23 will be packaged as a source tarball as before: ns-allinone-3.23.tar.bz2.

The tarball will contain:

  • Latest version of pybindgen
  • Latest version of netanim
  • ns-3.23
  • bake

where bake is used to fetch optional ns-3 components, including DCE.

A patch from ns-3.22 to ns-3.23 will also be posted.
