2.6.0

Happy New Year, everyone! 🎉

2026 is another year for LotAtc. I started this project 20 years ago! I am so proud to say that LotAtc is now a reference for GCI simulators, used not only by the DCS community but also to train numerous armies in France, Europe, the Middle East, South America, and Asia. 🌍

This year, 2026 will see the release of LotAtc 3.0 with a new map engine, new terrain engine, UI rework, network protocol update and many new features. I have been working hard on it, and even though I am running late (due to a heavy workload on the professional side), it is not far off! 🚀

In the meantime, I have released version 2.6.0. This version improves stability and adds enhancements, including support for DCS FARP.

Versioning

The 2.6.0 is compatible with 2.3.x or more branch

I have changed the rule for maintenance version. With recent development, I have a more stable network protocol. Starting with the 2.3, all minor version changes (2.3, 2.4,.2.5, ..) will be compatible each others.
