NumPy 1.15.3 release

[Charles R Harris]

Hi All,

On behalf of the NumPy team, I am pleased to announce the release of NumPy
1.15.3. This is a bugfix release for bugs and regressions reported
following the 1.15.2 release.  The most noticeable fix is probably for
the memory
leak <https://github.com/numpy/numpy/issues/12037> encountered when slicing
classes derived from Numpy.

The Python versions supported by this release are 2.7, 3.4-3.7. Wheels for
this release can be downloaded from PyPI
<https://pypi.org/project/numpy/1.15.3/>, source archives are available
from Github <https://github.com/numpy/numpy/releases/tag/v1.15.3>.

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 should look elsewhere or build
from source.
