That figures in number of the version mean...
  Actually all is extremely simple, for example give number:
ХХ.ХХ.ХХ
  The first block of figures (up to a point) designates the version of the program (varies only in cases when are brought any big changes in a code of the program).
  The second block of figures too designates the version of the program, but it will vary at fine/minor alterations
  The third block of figures displays quantity of languages supported at present.
Whether thus it is possible to be defined quickly is necessary for you to swing the new version or to remain on old (for example: to you quite enough unique languages, also are not present desire to swing updating only because there there was a support of two more).
