Systems and methods for automatically determining, for a version of a software developing project, which software component versions defined for an issue resolution at a particular time, for example, a time in the past, are included in the project version at the particular time. Such determination may include determining the software component versions included in an issue resolution at a particular time, and, for each determined version, determining whether the version is included in the project version. The software components that should be propagated to other versions of a software development project so that these versions have a complete issue resolution may be determined. Further, differences between software project versions, from an issue resolution prospective, may be determined.
