5.0
Released 4 January 2021
Breaking Changes
- Several breaking changes. See the Upgrade Guide for details.
Added
- Added support for the
Avx
instruction set. Plan a FFT with theFftPlanner
on a machine that supports AVX, and you'll get a 5x-10x speedup in FFT performance.
Changed
- Even though the main focus of this release is on AVX, most users should see moderate performance improvements due to a new internal architecture that reduces the amount of internal copies required when computing a FFT.
