The Dogtag version number consists of 4 numbers (..-). Currently the use of these numbers is not very well-defined and may not conform to some packaging guidelines.

The numbers should be used as follows:

• The number should indicate a major architectural change, a major rewrite, or a set of new major features. Backward compatibility may not be guaranteed.
• The number should indicate incremental changes over the last major change. New features can be added, but backward compatibility should be maintained. Old interface should be preserved but it can be deprecated.
• The number should indicate bug fixes over the last minor change or insignificant changes that only affect a limited scope.
• The number should indicate RPM packaging changes. The source code itself should not change, but patches can be applied on top of it by the RPM spec file.

Proposed milestone: 10.3
