v2.0.0

What's Changed

Added

• Added Hermitian FFT functions to SciPy interface mkl_fft.interfaces.scipy_fft: hfft, ihfft, hfftn, ihfftn, hfft2, and ihfft2 gh-161
• Added support for out kwarg to all FFT functions in mkl_fft and mkl_fft.interfaces.numpy_fft gh-157
• Added fftfreq, fftshift, ifftshift, and rfftfreq to both NumPy and SciPy interfaces gh-179

Changed

• NumPy interface mkl_fft.interfaces.numpy_fft is aligned with numpy-2.x.x gh-139, gh-157
• To set mkl_fft as the backend for SciPy is only possible through mkl_fft.interfaces.scipy_fft gh-179
• SciPy interface mkl_fft.interfaces.scipy_fft uses the same function from SciPy for handling s and axes for N-D FFTs gh-181

Fixed

• Fixed an issue for calling mkl_fft.interfaces.numpy.fftn with an empty axes gh-139
• Fixed an issue for calling mkl_fft.interfaces.numpy.fftn with a zero-size array gh-139
• Fixed inconsistency of input and output arrays dtype for irfft function gh-180
• Fixed issues with set_workers function in SciPy interface mkl_fft.interfaces.scipy_fft gh-183

Full Changelog: v1.3.14...v2.0.0

v1.3.14

resolves gh-152 by adding an explicit mkl-service dependency to mkl-fft when building the wheel
to ensure the mkl Python module is always available at runtime

resolves gh-115, gh-116, gh-119, gh-135

v1.3.13

Supported python versions are 3.9, 3.10, 3.11, 3.12

migrate from setup.py to pyproject.toml

includes support in virtual environment out of the box

the original mkl_fft.rfft and mkl_fft.irfft are renamed to mkl_fft.rfftpack and mkl_fft.irfftpack,
since they replicate the behavior from the deprecated scipy.fftpack module.

mkl_fft.rfft_numpy, mkl_fft.irfft_numpy, mkl_fft.rfft2_numpy, mkl_fft.irfft2_numpy,
mkl_fft.rfftn_numpy, and mkl_fft.irfftn_numpy are renamed to mkl_fft.rfft, mkl_fft.irfft,
mkl_fft.rfft2, mkl_fft.irfft2, mkl_fft.rfftn, and mkl_fft.irfftn, respectively.
(consistent with numpy.fft and scipy.fft modules)

file _scipy_fft_backend.py is renamed to _scipy_fft.py since it replicates scipy.fft module
(similar to file _numpy_fft.py which replicates numpy.fft module)

v1.3.11

Incremental release with updated installation instruction in readme, update to Cython 3, and fix for gh-109

v1.3.10

Bug fix release to support NumPy 2.0, addressing test suite failure on Windows.

v1.3.9

What's changed

mkl_fft now supports NumPy 2.0

v1.3.8

Release with vendored copy of numpy.distutils.conv_template. This allows mkl_fft to be build with Python 3.12 and NumPy >=1.25

1.3.7

Updated build system away from using numpy.distutils.

Updated code to compile with Cython 3.0

1.3.6

This release fixes issues with mkl_fft.interfaces.scipy_fft.

v1.3.3

Added mkl_fft.interfaces with numpy_fft and scipy_fft supported.

The scipy_fft updated to support new norm keyword values, and the plan parameter, although the only supported value is the default plan=None.
