INET-4.6.0 Released
This is a new feature release in the INET 4.x branch. Highlights include new protocol implementations for QUIC, Ethernet 10BASE-T1S, IPsec, and MRP; major refinements to the clock model; a reimplementation of IEEE 802.1AS (gPTP); and an important refactoring of the wireless physical layer's analog domain. The release continues to focus on improving correctness, accuracy, modularity, and long-term maintainability while addressing several long-standing limitations. Requires OMNeT++ 6.2 or later.

Chat with the AI - an OMNeT++ NotebookLM
We have added a new resource to assist users with learning OMNeT++ and writing their simulation projects. Located under the "Asking Questions" section, the OMNeT++ NotebookLM (https://nb.omnetpp.org) offers a dedicated Google Gemini powered notebook loaded with a collection of OMNeT++ and INET documentation. We will keep this notebook updated with the latest features and capabilities of the simulator. If you have any questions or need help with your simulation projects, please try this tool first. We ourselves use it for our daily work.
