## [1.9.0] — 2026-04-04

### Official Python Support
- **Python Binary Engine Added**: Officially supports Python 3.6+ environments. The new engine integrates optimization strategies modeled after robust C-API architectures (like `ORJSON`) to minimize serialization bottlenecks.

### Benchmark Industry Standardization
- **BMT-Level Framework Integration**: To avoid microbenchmark fallacies such as cache spikes and warmup noise associated with legacy custom timers, the benchmarking pipelines have been completely overhauled using industry-standard tools including `BenchmarkDotNet`, `mitata`, and `pytest-benchmark`.
- **Complex Real-World Test Models**: Scaled the measurement baselines by discarding simple 1D models in favor of the **ComplexRoundtripModel**—a comprehensive test suite invoking multi-dimensional hash maps and deep nested trees to ensure transparent, enterprise-level performance metrics.
