[Numpy-discussion] NumPy 1.20.0rc1 released

[Charles R Harris]

Hi All,

On behalf of the NumPy team I am pleased to announce the release of NumPy
1.20.0rc1. This NumPy release is the largest to date, containing some 654
merged pull requests contributed by 182 people. See the list of highlights
below. The Python versions supported for this release are 3.7-3.9, support
for Python 3.6 has been dropped. Wheels can be downloaded from PyPI
<https://pypi.org/project/numpy/1.20.0rc1/>; source archives, release
notes, and wheel hashes are available on Github
<https://github.com/numpy/numpy/releases/tag/v1.20.0rc1>. Linux users will
need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014
wheels.

*Highlights*

   - Annotations for NumPy functions. This work is ongoing and improvements
   can be expected pending feedback from users.
   - Wider use of SIMD to increase execution speed of ufuncs. Much work has
   been done in introducing universal functions that will ease use of modern
   features across different hardware platforms. This work is ongoing.
   - Preliminary work in changing the dtype and casting implementations in
   order to provide an easier path to extending dtypes. This work is ongoing
   but enough has been done to allow experimentation and feedback.
   - Extensive documentation improvements comprising some 185 PR merges.
   This work is ongoing and part of the larger project to improve NumPy's
   online presence and usefulness to new users.
   - Further cleanups related to removing Python 2.7. This improves code
   readability and removes technical debt.
   - Preliminary support for the upcoming Cython 3.0.
