Dec. 8, 2020

It's starting to get very cold (at least on the Northern hemisphere) so we have been carefully packaging a total of three new Python releases to keep you warm these days! Python 3.9.1 is the first maintenance release of Python 3.9, and also the first version of Python to support macOS 11 Big Sur natively on Apple Silicon. Go get it here: https://www.python.org/downloads/release/python-391/ Maintenance releases for the 3.9 series will continue at regular bi-monthly intervals, with **3.9.2** planned for Monday, 2021-02-08. Python 3.10a3 is the third alpha release of Python 3.10. You can get it here: https://www.python.org/downloads/release/python-3100a3/ Python 3.10a3 is the release preview of the next maintenance release of Python 3.8. You can get it here: https://www.python.org/downloads/release/python-387rc1/ Assuming no critical problems are found prior to **2020-12-21** , the currently scheduled release date for **3.8.7** , no code changes are planned between this release candidate and the final release. That being said, please keep in mind that this is a pre-release of 3.8.7 and as such its main purpose is testing. Your friendly release team, Ned Deily, Steve Dower, Pablo Galindo, Łukasz Langa

by Charles R Harris Dec. 3, 2020

Dec. 3, 2020

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. *Contributors* A total of 182 people contributed to this release.
