We strive to ship a new stable release once every trimester: each new release contains new features, bugs fixed, and ships with extensive documentation such as a tutorial, manual, etc.
- Latest release (ns-3.26): the source code tarball, list of new features, and documentation for the latest release.
- Errata for releases is maintained on the project wiki.
- Older releases are archived for those who might need them.
- The development tree is available for those who intend to contribute to the project or those who need to use the bleeding edge version of ns-3.
