'''The latest stable release of OpenSceneGraph is recommended for building FlightGear from git.''' | |||
You should use the unstable development releases (or build OSG from git) only if you intend to develop FlightGear against new features under development in OpenSceneGraph. For all other cases the latest stable release of OpenSceneGraph is usually the best option. | |||

Historically FlightGear has used [[PLIB]] instead of '''OpenSceneGraph'''. [[FlightGear 1.9.0]], released Decemeber 22, 2008, marked the release of the OSG version of FlightGear. While much of the conversion to OSG has happened over the years, [[PLIB]] is still used for some functions. | |||
Thanks to Mathias Fröhlich and Tim Moore, we can use recent OpenSceneGraph releases. | |||
