v0.1.0 - Initial public release

Release Notes

v0.1.0 (2026-03-12) - Initial Public Release

This is the first public release of the unified rdt_spatial_index
repository. It establishes a coherent baseline for development, external
evaluation, and reproducible benchmarking across Linux, macOS, and Windows.

What This Initial Release Includes

• Unified repository structure across source, tests, benchmarks, docs,
  publication artifacts, and legacy material.
• Multiple implementation paths with clear roles:
  • RDTFastIndex: recommended practical default,
  • RDTIndex: readable reference implementation,
  • RDTCIndex, RDTCythonIndex, RDTNumbaIndex: optional accelerated paths.
• Cross-platform CI coverage for unit checks and compiled backend validation.
• Public-facing documentation for installation, testing, benchmarking,
  reproducibility, and known limitations.

Recommended Starting Path

1. Install base package:

pip install .

2. Validate local environment:

python tests/run_tests.py
python tests/ci/verify_core_imports.py

3. If acceleration is required, build and verify compiled backends:

python rdt_spatial_index/c_ext/setup.py build_ext --inplace
python rdt_spatial_index/setup_cython.py build_ext --inplace
python tests/ci/verify_compiled_wrappers.py

Reproducibility and Benchmark Entry Points

python benchmarks/compare_indexes.py --n 50000
python benchmarks/pub_benchmark.py --fast
python benchmarks/generate_figures.py

Or run:

./run_publication_suite.sh --fast

Scope and Limitations

• This release does not claim universal superiority across all workloads.
• Performance conclusions are workload- and implementation-dependent.
• Some components are intentionally preserved as legacy/experimental material
  and are not the recommended production path.
• See LIMITATIONS.md and RESULTS_SUMMARY.md for evidence-based guidance.

Compatibility

• Python: 3.9+
• This release establishes the initial semantic version baseline: 0.1.0.
