The Free On-line Dictionary of Computing (19 January 2023):

version

    One of a sequence of copies of a program, each
   incorporating new modifications.  Each version is usually
   identified by a number, commonly of the form X.Y where X is
   the major version number and Y is the release number.
   Typically an increment in X (with Y reset to zero) signifies a
   substantial increase in the function of the program or a
   partial or total re-implementation, whereas Y increases each
   time the progam is changed in any way and re-released.

   Version numbers are useful so that the user can know if the
   program has changed (bugs have been fixed or new functions
   added) since he obtained his copy and the programmer can tell
   if a bug report relates to the current version.  It is thus
   always important to state the version when reporting bugs.
   Statements about compatibility between different software
   components should always say which versions they apply to.

   See change management.
