Semantic Versioning

Simply saying:

Given a version number MAJOR.MINOR.PATCH, increment the:

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

Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

The simplest thing to do is start your initial development release at 0.1.0 and then increment the minor version for each subsequent release.

If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you’re worrying a lot about backwards compatibility, you should probably already be 1.0.0.

Major version zero is all about rapid development. If you’re changing the API every day you should either still be in version 0.y.z or on a separate development branch working on the next major version
