.. _versioning:

Versioning
----------

Stem uses `semantic versioning <http://semver.org/>`_, which means that
**versions consist of three numbers** (such as '**1.2.4**'). These are used to
convey the kind of backward compatibility a release has...

 * The first value is the **major version**. This changes infrequently, and
   indicates that backward incompatible changes have been made (such as the
   removal of deprecated functions).

 * The second value is the **minor version**. This is the most common kind of
   release, and denotes that the improvements are backward compatible.

 * The third value is the **patch version**. When a stem release has a major
   issue another release is made which fixes just that problem. These do not
   contain substantial improvements or new features. This value is sometimes
   left off to indicate all releases with a given major/minor version.

.. _unreleased:
