NumPy 1.17.2 Release Notes#

This release contains fixes for bugs reported against NumPy 1.17.1 along with a some documentation improvements. The most important fix is for lexsort when the keys are of type (u)int8 or (u)int16. If you are currently using 1.17 you should upgrade.

The Python versions supported in this release are 3.5-3.7, Python 2.7 has been dropped. Python 3.8b4 should work with the released source packages, but there are no future guarantees.

Downstream developers should use Cython >= 0.29.13 for Python 3.8 support and OpenBLAS >= 3.7 to avoid errors on the Skylake architecture. The NumPy wheels on PyPI are built from the OpenBLAS development branch in order to avoid those errors.
