v1.0.0
nifty-ls is now production-ready! v1.0.0 has been released on PyPI and includes finufft and cufinufft (CUDA) backends, astropy integration, support for batched periodograms, and more. Performance on the CPU is often 5-10x faster than Astropy LombScargle, and 6 orders of magnitude more accurate (no more twiddling with oversample factors!).
