It has been suggested that Post FlightGear 2020.2 LTS changes be merged into this article or section.

This page sets out what is planned for the LTS following 2020.3. For ease of reference, this is referred to as 2022.X, though there is no guarantee that all features listed will be in that release, or that it will be released in 2022!


  • Make CMake 3.6 the minimum required version: this will allow simplifying a bunch of compatibility logic in the build files while fixing OSGText Issues and broken event handling in CompositeViewer Support mode (There were issues with some Linux distributions only having OSG 3.4 in their repos, but we will need to compile OSG with custom flags anyway for the core profile, so it should be fine.[1] ) [2] [3]
