[SciPy-User] NumPy 1.15.1 released.

Charles R Harris
Hi All,

On behalf of the NumPy team, I am pleased to announce the release of NumPy 1.15.1. This is a bugfix release for bugs and regressions reported following the 1.15.0 release. Noticeable fixes are

  • The annoying but harmless RuntimeWarning that "numpy.dtype size changed" has been suppressed. The long standing suppression was lost in the transition to pytest.
  • The update to Cython 0.28.3 exposed a problematic use of a gcc attribute used to prefer code size over speed in module initialization, possibly resulting in incorrect compiled code. This has been fixed in latest Cython but has been disabled here for safety.
  • Support for big-endian and ARMv8 architectures has been improved.
The Python versions supported by this release are 2.7, 3.4-3.7. The wheels are linked with OpenBLAS v0.3.0, which should fix some of the linalg problems reported for NumPy 1.14. Wheels for this release can be downloaded from PyPI, source archives are available from Github.

Compatibility Note

The NumPy 1.15.x OS X wheels released on PyPI no longer contain 32-bit binaries.  That will also be the case in future releases. See
#11625 for the related discussion.  Those needing 32-bit support on the Mac should look elsewhere or build from source.
