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

The NumPy 1.21.3 is a maintenance release the 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.
