OxiFFT 0.4.0 Released — Distributed Real FFTs and Wisdom That Actually Learns
Pure Rust FFT and the rustfft replacement. OxiFFT 0.4.0 adds distributed real (r2c/c2r) MPI transforms, wires wisdom-based auto-tuning into MEASURE/PATIENT/EXHAUSTIVE planning so it really compares candidate algorithms, corrects the MSRV to 1.87, and ships a breaking cleanup of dead planner code plus a v2 wisdom binary format.
