0.6.1

0.6.1 2025-10-10, 0.6.0 2025-10-05

Combine python bindings project into rust crate to streamline development process.
Implement PGO (profile-guided optimization) for python releases, giving a 1.2-2x speedup for
dimensions 1-4 at the expense of a ~2x slowdown for higher dimensions.

Changed - 0.6.1

• Python
  • Pass PGO profile-use argument for rustc via maturin args instead of RUSTFLAGS to avoid overriding flags set in .cargo/config.toml
  • Split PGO scripts into native and distribution variants
    • Distribution variant tests the exact build configuration used for distribution
    • Native variant builds with target-cpu=native to enable all available instruction sets
  • Update baked PGO profile based on distribution build
  • Only run pypi distribution for single python version, because ABI3 build is portable to later python versions
• Rust
  • Add x64 to platforms where extra instruction sets are enabled in .cargo/config.toml to capture windows 64-bit x86

Changed - 0.6.0

• Python
  • Port python project from interpnpy repo
  • Implement PGO with hand-tuned profile workload
  • !Set linearize_extrapolation=True as default for cubic interpolators
  • Use pytest-cov for coverage testing
  • Update test deps & add linter/formatter configuration
  • Add uv lock and uv cache configuration
  • Use uv for actions
  • Add more vector instruction sets for x86_64 targets reflecting a ~2015-era CPU
• Rust
  • Eliminate some length check error handling that is no longer necessary for const-generic flattened methods
  • Add PyO3 bindings from python project as python.rs module behind python feature gate
