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 <https://pypi.org/project/numpy/1.15.1/>, source archives are
available from Github <https://github.com/numpy/numpy/releases/tag/v1.15.1>.


*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 <https://github.com/numpy/numpy/issues/11625> for the related
discussion.  Those needing 32-bit support on the Mac should look elsewhere
or build from source.
