I think more people are starting to use semantic versioning: http://semver.org/

The gist of it is:
Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

This way the numbers actually mean something in a somewhat consistent way across programs.
npm packages use this for example.
