NumPy 1.21.1 Release Notes

The NumPy 1.21.1 is maintenance release that fixes bugs discovered after the 1.21.0 release and updates OpenBLAS to v0.3.17 to deal with problems on arm64.

The Python versions supported for this release are 3.7-3.9. The 1.21.x series is compatible with development Python 3.10. Python 3.10 will be officially supported after it is released.

:warning: There are unresolved problems compiling NumPy 1.20.0 with gcc-11.1.

• Optimization level -O3 results in many incorrect warnings when running the tests.
• On some hardware NumPY will hang in an infinite loop.
