All notable changes to boxic_dmn will be documented in this file.

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

Unreleased

0.3.0 - 2026-07-24

  • Breaking: accept DMN 1.5 (20230324) as the sole executable and emitted profile; older documents remain available only through best-effort inspection.
  • Make formally released DMN 1.5 (20230324) the sole executable and emitted profile; retain explicit best-effort inspection for older documents.
  • Add strict schema/profile/model loading, packaged normative schemas, bounded secure XML handling, and stable public diagnostics.
  • Replace sibling scanning with declared, confined file imports and explicit in-memory import maps/resolvers.
  • Centralize definitions/local FEEL language inheritance and preserve omitted declarations in the normalized model.
  • Add capability-specific validation and decision-service evaluator options.
  • Isolate trusted external functions from model input, define built-in precedence, and redact host failures.
  • Publish the conformance contract and construct capability ledger.
  • Validate all 1,485 selected DMN cases against TCK revision a162739daee85fb28e9d3bec2f306505992dae0f without failures, errors, missing cases, or unsupported cases.

0.2.0 - 2026-07-19

  • Add deterministic DMN 1.4 XML encoding through Boxic.DMN.encode_xml/2.
  • Add structured serialization preflight errors and explicit rejection of version-mismatched or lossy loaded models.
  • Retain the source DMN profile, import declarations, and serialization fidelity on normalized models.
  • Preserve semantically significant FEEL text whitespace during loading.
  • Add immutable, ID-based decision-table authoring operations for cells, rules, inputs, outputs, ordering, and hit policies.
  • Validate focused generated-document fixtures against the vendored official DMN 1.4 schema.
  • Add generated-model, injection, XML-code-point, bounded-error, atom-safety, deep-recursion, and standalone large-table performance coverage.
  • Audit all 69 distinct models in the implemented TCK writer profile: all 69 are explicitly rejected for their newer DMN namespace, with zero writer failures or implicit version conversions.

0.1.0 - 2026-07-18

  • Initial public release.
  • Load and normalize DMN 1.4 XML models.
  • Validate model structure, types, and references.
  • Evaluate decisions, decision tables, boxed expressions, business knowledge models, imports, and decision services.
  • Validate against DMN TCK revision 0dbcaf9b98bc3af4e36d44a7aed95e9e85703a13.
  • Pass all 1,485 cases in the pinned DMN TCK profile.
