Unreleased

0.2.0 - 2026-07-24

  • Add options-aware expression, AST, and unary-test evaluation with a private trusted external-function environment.
  • Keep built-ins ahead of registered functions by default, allow explicit host opt-in to registered precedence, and redact host exceptions.
  • Validate against DMN TCK revision a162739daee85fb28e9d3bec2f306505992dae0f: 2,042 cases pass and the 18 Java-specific external-function cases remain explicitly unsupported.

The project follows Semantic Versioning. While the package is below version 1.0.0, breaking changes increment the minor version.
