Download: https://pypi.org/project/Cython/3.0a3/ Changelog: https://github.com/cython/cython/blob/master/CHANGES.rst This release was brought to you with the invaluable help of Yusuf Cat Stevens and Deutsche Bahn. Thanks to everyone out there who's doing their job keeping others alive/healthy/undepressed/fed/mobile/connected/working/… in these (for many people) difficult days.
