The major new features and changes from 2.3 are:

• Type 3 transforms on the GPU (cufinufft), in 1,2,3 dims.
• MATLAB gpuArray interface to cufinufft, with docs and demos
• spreadinterponly options to do spreading/interp only in type1,2
• Performance improvement via upsampfac heuristic choice
• Improved testing, including cufinufft and MATLAB/Octave tests
• Internal code improvements and templating
• Various bugfixes
• Fixed accuracy loss in 2.4.0-rc1 due to upsampfac heuristic choice

See CHANGELOG for the full list.

v2.3.1 (minor update)

FINUFFT Release 2.3.1

this is a minor update release, to help the MRI community. (Major new features will go to 2.4.0 instead.)

Features:

• support and documentation for gpu_spreadinterponly option (affects GPU only)

v2.3.0

FINUFFT release 2.3.0 (stable)

This release includes many new features since 2.2.0. The main ones are:

• major performance improvements in CPU spread/interpolation through manual SIMD vectorization
• performance improvements for the GPU library
• switchable FFT: either FFTW3 or DUCC0 (where the latter exploits sparse block structure for speed in 2D and 3D)
• modernized Python wrapping
• revamped CMake build
• many bugfixes, improved testing and benchmarking, new documentation...

See CHANGELOG for the full list.

v2.3.0-rc1

Release candidate for 2.3.0.

This contains a long list of improvements, including major ones, documented in the CHANGELOG.

v2.2.0

FINUFFT release 2.2.0.

• First release to have CPU+GPU combined in the same repo
• GPU interface has been changed slightly for forwards compatibility (relative to legacy v1.3 cufinufft)
• Extension of GPU interface for compatibility with CuPy, PyTorch, and Numba frameworks in addition to PyCuda
• Support of CUDA streams
• CMake build system
• Various speed improvements and bugfixes
• Improved documentation

See all changes described in the CHANGELOG

v2.1.0

FINUFFT version 2.1.0, with professionalized name-safe lib symbols and headers, and plenty of other improvements described in the CHANGELOG.

v2.0.4

Maintenance release: bug fixes, documentation improvements, cleaner Fortran examples. No changes in interface or performance.

v2.0.3

Finally thread-safety (enabled by -DFFTW_PLAN_SAFE, needs FFTW>=3.3.6, hence not yet enforced by default), plus a couple of important bug and doc fixes. See CHANGELOG.

v2.0.2 stable

FINUFFT v2.0.2 stable release.

See CHANGELOG for new features and changes.
