Changelog#

v1.1.0 (2023-06-13)#

This release features a change in the build system from distutils, which is scheduled for removal in Python 3.12, to meson and meson-python. It includes the building of wheels for ppc64le and s390x (on x86_64 only) and removes building of all 32-bit wheels and macOS universal2 wheels.

This release supports Python 3.8 to 3.11.

Thanks to new contributor @eli-schwartz.
