The version number of this application consists of a given version in the format of 'v1.0.0' (formely only 2 digits).
Where the first number indicates a major release and the second and third numbers indicate minor changes.
Versions, including release candidates and path-levels, are tagged in git.
Versions, including release candidates and patch-levels, are tagged in git.
@subsection rc Release Candidates
Release candidates are software versions that seem stable and functional to become a new version but testing is not fully finished. These versions are marked with an '-rcX', where X is the number of the release candidate.
