Sourced from interpn's releases.

0.11.0 2026-01-15

Changed

• !Remove recursive implementations
  • All dimensionalities now use const-generic bounded implementations
  • For dimensions higher than const-unrolling limit, a run-time loop of the same form is used
  • No notable change in performance for high dimensions
  • No change to API for ::interpn convenience functions
  • All methods are now compatible with static analysis of memory usage via cargo-call-stack
• Refactor internals to reduce duplication
• Improve form of early bounds checks to be interpreted correctly by the compiler
  • 30% speedup in some cases, no effect on most
  • Bounds checks done via iterator do not always result in optimizing out panic branches
• Test cubic methods in higher dimensions

0.10.0 2026-01-10

Added

• Rust
  • Add top-level interpn, interpn_alloc and interpn_serial methods along with supporting enums for selecting methods
  • Add par feature, enabled by default, that enables parallelism with rayon in interpn function
  • Add lazy static for getting number of physical cores to advise thread chunk sizes

Changed

• Rust
  • Update deps
• Python
  • !Refactor interpn function
    • Combine check_bounds: bool and bounds_check_atol: float to check_bounds_with_atol: float | None
    • Replace assume_regular input with optional grid_kind to allow assuming either regular or rectilinear, or making no assumption
    • Add max_threads: int | None input to allow manually limiting parallelism
    • Use rust top-level interpn function as backend for method selection, bounds checks, and parallelism

0.9.1 2025-12-31

Changed

• Rust
  • Remove explicit const-unrolling for shallow loops (eliminates nested const-unrolling)
    • Improves compile time
    • Minimal effect on performance in Rust benchmarks
    • About 20% improvement for single-sample throughput from Python
• Python
  • Lock python package version to rust version
  • Improve handling of __version__ when package is not present
