OMNeT++ Older Versions

This is a maintenance release of omnetpp-6.0. This release contains updated JRE and Eclipse dependencies for the IDE to fix several crashes with recent Gtk library versions on Linux. It also contains numerous fixes to the simulation kernel, Qtenv, and the Analysis Tool and the NED Documentation Generator in the IDE.

Experimental AARCH64 based versions are available for Linux and macOS.

This is a maintenance release which contains more than two dozen bugfixes in the simulation runtime, the IDE, the Analysis Tool, the NED documentation generator and Qtenv. The documentation was also updated in various places including the Install Guide.

An experimental AARCH64 based Linux version is available here.

Release 5.0 is a result of development effort of nearly two years. This is a major release that introduces significant new features compared to the last 4.x version, for example the Canvas API (2D graphics), OpenSceneGraph-based 3D graphics support, improved logging, a new Qt-based runtime environment that will eventually replace Tkenv, and much more.

We have also taken the opportunity of the major release to improve several corners of the OMNeT++ API, and also to get rid of deprecated functionality. For porting models from OMNeT++ 4.x, see doc/API-changes.txt which lists all changes, with hints on how to update the model code.
