NumPy 1.18.1 released

Charles R Harris
Hi All,

On behalf of the NumPy team I am pleased to announce that NumPy 1.18.1 has been released. This release contains fixes for bugs reported against NumPy 1.18.0. Two bugs in particular that caused widespread problems downstream were:
  • The cython random extension test was not using a temporary directory for building, resulting in a permission violation. Fixed.
  • Numpy distutils was appending -std=c99 to all C compiler runs, leading to changed behavior and compile problems downstream. That flag is now only applied when building numpy C code.
The Python versions supported in this release are 3.5-3.8. Downstream developers should use Cython >= 0.29.14 for Python 3.8 support and OpenBLAS >= 3.7 to avoid errors on the Skylake architecture.  Wheels for this release can be downloaded from PyPI, source archives and release notes are available from Github.
