Released 16 April 2021

Added

  • Implemented a code path for SSE-optimized FFTs (Thanks to Henrik Enquist!) (#60)
    • Plan a FFT using the FftPlanner (or the new FftPlannerSse) on a machine that supports SSE4.1 (but not AVX) and you'll see a 2-3x performance improvement over the default scalar code.

Fixed

  • Fixed underflow when planning an AVX FFT of size zero (#56)
  • Fixed the FFT planner not being Send, due to internal use of Rc<> (#55)
  • Fixed typo in documentation (#54)
  • Slightly improved numerical precision of Rader's Algorithm and Bluestein's Algorithm (#66, #68)
  • Minor optimizations to Rader's Algorithm and Bluestein's Algorithm (#59)
  • Minor optimizations to MixedRadix setup time (#57)
  • Optimized performance of Radix4 (#65)
