We follow Semantic Versioning. We extended the standard semantic versioning with an additional format version. The version W.X.Y.Z indicates:

  • W is the format version (data representation is backward-incompatible),

  • X is the major version (library interface is backward-incompatible),

  • Y is the minor version (library interface is extended, but backward-compatible), and

  • Z is the patch version (backward-compatible bug fix).
