Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.21.1. The NumPy 1.21.1 is a maintenance release that fixes bugs discovered after the 1.21.0 release. OpenBLAS has also been updated to v0.3.17 to deal with arm64 problems. The Python versions supported for this release are 3.7-3.9. The 1.21.x series is compatible with development Python 3.10 and Python 3.10 will be officially supported after it is released. Wheels can be downloaded from PyPI https://pypi.org/project/numpy/1.21.1/; source archives, release notes, and wheel hashes are available on Github https://github.com/numpy/numpy/releases/tag/v1.21.1. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 11 people contributed to this release.
