Privoxy version numbers consist of three numbers, separated by dots, like in X.Y.Z (e.g.
3.0.0), where: X, the version major, is rarely ever changed. Majors 1 and 2 were Junkbuster , and 3 is the first stable Privoxy release. Y, the version minor, is increased for every release except for pure bug fix releases in which case only
Z, the point or sub version, is increased.
