Hi All,

On behalf of the NumPy team, I am pleased to announce the release of NumPy
This is a bugfix release for bugs reported following the 1.14.3 release. The
most significant fixes are:

* fixes for compiler instruction reordering that resulted in NaN's not being
  properly propagated in `np.max` and `np.min`,

* fixes for bus faults on SPARC and older ARM due to incorrect alignment

There are also improvements to printing of long doubles on PPC platforms.
is not yet perfect on that platform, the whitespace padding is still
and is to be fixed in numpy 1.15, consequently NumPy still fails some
printing-related (and other) unit tests on ppc systems. However, the printed
values are now correct.

Note that NumPy will error on import if it detects incorrect float32 `dot`
results. This problem has been seen on the Mac when working in the Anaconda
enviroment and is due to a subtle interaction between MKL and PyQt5.  It is
strictly a NumPy problem, but it is best that users be aware of it.  See the
gh-8577 NumPy issue for more information.

The Python versions supported in this release are 2.7 and 3.4 - 3.6. Wheels
for all supported versions  are available from PIP
<https://pypi.org/project/numpy/> and source releases are available
on github <https://github.com/numpy/numpy/releases/tag/v1.14.4>. The source
releases were cythonized with Cython 0.28.2 and should
be compatible with the upcoming Python 3.7.
