Production Readiness -This release brings major enhancements aligned with the TypeScript v1.3.0 implementation, focusing on adaptive encoding, developer experience, and production-ready features. +This release brings major enhancements aligned with the TypeScript v1.3.0 implementation, focusing on adaptive encoding, binary format, versioning, developer tools, and production-ready features. ### Added +#### Binary Format (ZON-B) +- **MessagePack-Inspired Encoding**: Compact binary format with magic header (`ZNB\x01`) +- **40-60% Space Savings**: Significantly smaller than JSON while maintaining structure +- **Full Type Support**: Primitives, arrays, objects, nested structures +- **APIs**: `encode_binary()`, `decode_binary()` with round-trip validation +- **Test Coverage**: 27 tests for binary format + +#### Document-Level Schema Versioning +- **Version Embedding/Extraction**: `embed_version()` and `extract_version()` for metadata management +- **Migration Manager**: `ZonMigrationManager` with BFS path-finding for schema evolution +- **Backward/Forward Compatibility**: Automatic migration between schema versions +- **Utilities**: `compare_versions()`, `is_compatible()`, `strip_version()` +- **Test Coverage**: 39 tests covering all versioning scenarios + #### Adaptive Encoding System -- **4 Encoding Modes**: `compact`, `readable`, `llm-optimized` for optimal output +- **3 Encoding Modes**: `compact`, `readable`, `llm-optimized` for optimal output - **Data Complexity Analyzer**: Automatic analysis of nesting depth, irregularity, field count - **Mode Recommendation**: `recommend_mode()` suggests optimal encoding based on data structure - **Intelligent Format Selection**: `encode_adaptive()` with customizable options - **Test Coverage**: 17 tests for adaptive encoding functionality +#### Developer Tools +- **Helper Utilities**: `size()`, `compare_formats()`, `analyze()`, `infer_schema()`, `compare()`, `is_safe()` +- **Enhanced Validator**: `ZonValidator` with linting rules for depth, fields, performance +- **Test Coverage**: 37 tests for developer tools + ### Changed - **Version**: Updated to 1.2.0 for feature parity with TypeScript package -- **API**: Added `encode_adaptive()` as high-level encoding function +- **API**: Expanded exports to include binary, versioning, and tools modules - **Documentation**: Aligned with TypeScript v1.3.0 feature set ### Performance +- **Binary Format**: 40-60% smaller than JSON +- **ZON Text**: Maintains 16-19% smaller than JSON - **Adaptive Selection**: Automatically chooses best encoding for your data -- **Mode Optimization**: Each mode tuned for specific use cases (compression, readability, LLM clarity) -- **Test Suite**: All 237 tests passing +- **Test Suite**: All 340 tests passing (up from 237) ## [1.1.0] - 2024-12-01 diff --git a/zon-format/src/zon/__init__.py b/zon-format/src/zon/__init__.py index 842d627..051015a 100644 --- a/zon-format/src/zon/__init__.py +++
