Unfortunately, due to various circumstances and problems, it was decided that the FlightGear v3.6 release would be skipped (see FlightGear Newsletter November 2015),[1] and that the development focus would shift to the FlightGear v3.8 release. In addition, through debates raised by the delays leading up to the cancellation, it was decided to pursue the automation of the release cycle through the use of scripts in the FlightGear build server.

Although not a true, official version, FlightGear v3.6 Release Candidate contains many exciting new features, enhancements and bug fixes. Highlights include a reduced base installation size, a new integrated Qt-based launcher, improvements to the built-in web UI, cockpit shadows without Rembrandt, and massive improvements to the Cessna 172P.

If users want to download the 3.6 Release Candidate (which may be unstable), they can do so here.
