Highlights of this release are the use of the LLDB debugger inside the IDE, as well as numerous Qtenv improvements: display of documentation brief in module/submodule tooltips, log filtering, and the display of an identicon.
Issues fixed in version 6.2.0.

DetailsRostock, Germany - The OMNeT++ development team was invited to present a tutorial on Time-Sensitive Networking (TSN) at the 21st IEEE International Conference on Factory Communication Systems (WFCS 2025). The conference took place in Rostock, Germany, from June 10-13, 2025.
The 90-minute tutorial, “Simulating Time-Sensitive Networking (TSN) with OMNeT++ and INET,” was held on the conference’s Tutorial Day. It was presented by Levente Mészáros, a Senior Software Engineer for the OMNeT++/INET Framework.
The session provided a practical introduction to simulating TSN technologies using the OMNeT++ discrete-event simulator and the INET Framework model library. The presentation gave an overview of OMNeT++ simulation concepts and demonstrated how the INET Framework facilitates the modeling of TSN networks and traffic. The tutorial highlighted key TSN scenarios through live demonstrations, covering cut-through switching, frame preemption, scheduling and traffic shaping, and time synchronisation, among other topics.
The tutorial was designed for researchers, graduate students, and industry practitioners looking to evaluate TSN solutions. It aimed to provide attendees with a practical understanding of how to model and assess key TSN mechanisms. The goal was for participants to feel confident in building their own TSN simulations, configuring relevant parameters, and using the results to guide design and implementation decisions.
As the only IEEE conference exclusively focused on communication for industrial automation systems, WFCS was an ideal venue to showcase the powerful capabilities of OMNeT++ and INET for TSN research and development.
DetailsDo you like using the pip command for installing Python packages? Pip makes
package installation a breeze. Now imagine if you could install OMNeT++
simulation models and model frameworks just as easily…
This update marks a significant refinement of OMNeT++ since version 6.0, impacting virtually every aspect of the simulation framework, including the IDE and simulation library. Among the various enhancements, the Analysis Tool stands out with major improvements to both its user interface and its underlying chart templates and Python library. For example, the new, highly customizable number and quantity formatting options facilitate the interpretation of raw simulation results displayed in the user interface; chart legends became much more customizable; and the enhanced plotting of enum-valued vectors allows much more appropriate visualization.
Additional notable updates include the ability to denote ini file sections as “abstract” (meaning they merely serve as base for further configurations); the validation of parameter values according to the @enum property; a new bookmarking feature and other enhancements in the Qtenv log window; a more streamlined operation of Project Features in the IDE; the possibility to have simulation programs dump the stack trace in the case of crashes; a new Python library for reading and querying NED files; and much more.
Important: Please read the installation instructions even if you are familiar with OMNeT++, as there are new dependencies and the recommended way of installing Python packages has also changed. There is a new install.sh script in the root of the source distribution that will help you install OMNeT++ on your machine.
