Configuration Management Module-based systems can be shipped in various configurations of components defining the system’s functionality and performance. Different configurations are referred to as product versions or product editions. Sequential modifications of a configuration corresponding to product releases are identified as major versions. Sequential modifications of the same major release configuration are identified by minor versions. During development & testing current pre-release version is identified by the build number. Product Edition V Major . Minor . Build Number E.g. Sonar Producer v 5.1.1012 Keeping track of version is a must for phased development!
