Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

The FlightGear development team is delighted to announce the v2018.4 release of FlightGear, the free, open-source flight simulator. This new version contains many exciting new features, enhancements and bugfixes.

Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in universities and for interactive exhibits in museums.

FlightGear features more than 400 aircraft, a worldwide scenery database, a multiplayer environment, detailed sky modeling, a flexible and open aircraft modeling system, varied networking options, multiple display support, a powerful scripting language, and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute.

FlightGear v2018.4 is not released yet, and might be renamed to 2019.1.
