Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.22.2. NumPy 1.22.2 fixes several bugs discovered after the 1.22.1 release. Notable fixes are: - Build related fixes for downstream projects and other platforms. - Various annotation fixes/additions. - Fixes for the CVE-2021-41495 complaint. - Toolchain fixes on Windows. Numpy wheels now use the 1.41 tool chain, fixing downstream link problems for projects using NumPy provided libraries on Windows. Note that OSX wheels are provided for both the x86_64 and arm64 architectures, but there are no universal2 wheels. The minimum supported OS X version is now 10.14 for the former and 11.0 for the latter. The Python versions supported in this release are 3.8-3.10. Wheels can be downloaded from PyPI https://pypi.org/project/numpy/1.22.2; source archives, release notes, and wheel hashes are available on Github https://github.com/numpy/numpy/releases/tag/v1.22.2. Linux users will need pip >= 0.19.3 in order to install the manylinux2014 wheels. *Contributors* A total of 14 people contributed to this release.
