FlightGear CVS

Most of the volunteers around the world who help develop FlightGear use CVS, a Concurrent Versions System to store all of the files required. CVS keeps track of every update as many developers work together, concurrently, to create new versions of the files used to compile and build FlightGear.

This means the newest features, fixes, and additions to FlightGear, which are still in development, are available in CVS before they are available in the stable release. CVS is a tool for users who want to build the newest possible version of FlightGear from source code, or experiment with new aircraft or other features which are not yet available in the stable release version.

However, CVS is a tool for advanced users and developers. Using CVS can expose the user to unstable features which spew ugly error messages or crash the computer. Fortunately, CVS is not required, even for advanced users, to use the stable release versions of FlightGear. See Getting Started for info on using FlightGear without CVS.

FlightGear and CVS

FlightGear's CVS is available here and can be considered as the most up-to-date version of the FlightGear source and aircraft. To run CVS aircraft the user need to use the CVS, to prevent bugs and faults. The CVS Changelog shows all updates made to the CVS repository.
