[SciPy-Dev] Pythran 0.9.4 - Hollsent

[Serge Guelton]

Hi folks,

It's always a pleasure to announce a Pythran release, and here we go for a
version bump!

Short reminder: Pythran is an ahead-of-time compiler for scientific Python,
with a focus on high-level numerical kernels, parallelism and vectorisation.

Here is a simple kernel example, with a pythran annotation. Note that this
kernel is still Python-compatible (from https://stackoverflow.com/questions/50658884):

    #pythran export euclidean_distance_square(float64[1,:], float64[:,:])
    import numpy as np
    def euclidean_distance_square(x1, x2):
        return -2*np.dot(x1, x2.T) + np.sum(np.square(x1), axis=1)[:, np.newaxis] + np.sum(np.square(x2), axis=1)

The Pythran package is available on PyPI, Github and Conda

    https://pypi.org/project/pythran/
    https://anaconda.org/conda-forge/pythran
    https://github.com/serge-sans-paille/pythran

Packages exist for archlinux and Fedora, they'll probably be updated soon :-)

The interested reader can have a look to the changelog for details

    https://pythran.readthedocs.io/en/latest/Changelog.html

Most notably, this release provides support for Python 3.7 and Python 3.8, as
well as the ability to use clang-cl as a (better) backend compiler for Windows.
