$ReleaseNumber

$ReleaseNumber
is an integer which gives the current Mathematica kernel release number, and increases in successive releases.
  • Each released revision of the Mathematica kernel for any particular computer system is assigned a version number, followed by a release number.
  • The same source code may yield releases with different numbers on different computer systems.
  • In a typical full version number, such as 1.0.3, the last integer is the release number.
