Landing Page for Links to the Helios 1.4 Project Helios 1.4 now resides at https://github.com/BlueFinBima/Helios14, and is no longer accepting new issues.
Helios 1.6 is the next step in the journey, and a lot of work has taken place under the covers, principally by @derammo and his team of testers, which will provide a foundation for future improvements to the virtual cockpit environment. The last release of the BlueFinBima fork of Helios 1.4 can still be downloaded, however the future is very definitely Helios 1.6 whose releases will appear here.
The Helios 1.4 Wiki remains available, however the only wiki to be maintained is at Helios Virtual Cockpit
