A release candidate (RC) is a software build that has the potential to become a stable release, unless significant bugs are discovered in testing. Release candidates are intended for more advanced (or adventurous!) users who are comfortable testing early versions of software that are potentially buggier than stable releases.

The Qubes OS Project uses the  semantic versioning standard. Version numbers are written as <major>.<minor>.<patch>. Hence, releases that increment the second value are known as “minor releases.” Minor releases generally include new features, improvements, and bug fixes that are backward-compatible with earlier versions of the same major release. See our  supported releases for a comprehensive list of major and minor releases and our  version scheme documentation for more information about how Qubes OS releases are versioned.
