This will: - Allow maintainers to determine when the minimum version of a 3rd party piece of software can be increased without negatively impacting supported platforms. - Allow tailoring of CI environments to match the intended supported build platforms.

These +platforms are used as the basis for deciding upon the minimum required +versions of 3rd party software QEMU depends on. The supported platforms +are the targets for automated testing performed by the project when patches +are submitted for review, and tested before and after merge. + +If a platform is not listed here, it does not imply that QEMU won't work. +If an unlisted platform has comparable software versions to a listed platf= orm, +there is every expectation that it will work. Bug reports are welcome for +problems encountered on unlisted platforms unless they are clearly older +vintage than what is described here. + +Note that when considering software versions shipped in distros as support +targets, QEMU considers only the version number, and assumes the features = in +that distro match the upstream release with the same version. In other wor= ds, +if a distro backports extra features to the software in their distro, QEMU +upstream code will not add explicit support for those backports, unless the +feature is auto-detectable in a manner that works for the upstream releases +too. + +The Repology site @url{https://repology.org} is a useful resource to ident= ify +currently shipped versions of software in various operating systems, though +it does not cover all distros listed below. + +@section Linux OS + +For distributions with frequent, short-lifetime releases, the project will +aim to support all versions that are not end of life by their respective +vendors. For the purposes of identifying supported software versions, the +project will look at Fedora, Ubuntu, and openSUSE distros.
