========================== NumPy 1.21.3 Release Notes

NumPy 1.21.3 is a maintenance release that fixes a few bugs discovered after 1.21.2. It also provides 64 bit Python 3.10.0 wheels. Note a few oddities about Python 3.10:

There are no 32 bit wheels for Windows, Mac, or Linux.
The Mac Intel builds are only available in universal2 wheels.

The Python versions supported in this release are 3.7-3.10. If you want to compile your own version using gcc-11, you will need to use gcc-11.2+ to avoid problems.
