[Numpy-discussion] NumPy 1.17.0rc2 released

[Charles R Harris]

Hi All,

On behalf of the NumPy team I am pleased to announce the release of NumPy
1.17.0rc2. The 1.17 release contains a number of new features that should
substantially improve its performance and usefulness. The Python versions
supported are 3.5-3.7, note that Python 2.7 has been dropped. Python 3.8b2
should work with the released source packages, but there are no guarantees
about future releases. Highlights of this release are:

   - A new extensible random module along with four selectable random
   number generators and improved seeding designed for use in parallel
   processes has been added. The currently available bit generators are
   MT19937, PCG64, Philox, and SFC64.
   - NumPy's FFT implementation was changed from fftpack to pocketfft,
   resulting in faster, more accurate transforms and better handling of
   datasets of prime length.
   - New radix sort and timsort sorting methods. It is currently not
   possible to choose which will be used, but they are hardwired to the
   datatype and used when either ``stable`` or ``mergesort`` is passed as the
   method.
   - Overriding numpy functions is now possible by default

Downstream developers should use Cython >= 0.29.10 for Python 3.8 support
and OpenBLAS >= 3.7 (not currently out) to avoid problems on the Skylake
architecture. The NumPy wheels on PyPI are built from the OpenBLAS
development branch in order to avoid those problems. Wheels for this
release can be downloaded from PyPI
<https://pypi.org/project/numpy/1.17.0rc2/>, source archives and release
notes are available from Github
<https://github.com/numpy/numpy/releases/tag/v1.17.0rc2>.
