NumPy 1.14.0 release

[Charles R Harris]

Hi All,

On behalf of the NumPy team, I am pleased to announce NumPy 1.14.0. Numpy
1.14.0 is the result of seven months of work and contains a large number of
bug fixes and new features, along with several changes with potential
compatibility issues. The major change that users will notice are the
stylistic changes in the way numpy arrays and scalars are printed, a change
that will affect doctests. See the release notes for details on how to
preserve the old style printing when needed.

A major decision affecting future development concerns the schedule for
dropping Python 2.7 support in the runup to 2020. The decision has been
made to support 2.7 for all releases made in 2018, with the last release
being designated a long term release with support for bug fixes extending
through the end of 2019. Starting from January, 2019 support for 2.7 will
be dropped in all new releases. More details can be found in the relevant
NEP
<https://github.com/numpy/numpy/blob/master/doc/neps/dropping-python2.7-proposal.rst>
.

This release supports Python 2.7 and 3.4 - 3.6. Wheels for the release are
available on PyPI. Source tarballs, zipfiles, release notes, and the
changelog are available on github
<https://github.com/numpy/numpy/releases/tag/v1.14.0>.


*Highlights*

   - The ``np.einsum`` function uses BLAS when possible

   - ``genfromtxt``, ``loadtxt``, ``fromregex`` and ``savetxt`` can now
   handle files with arbitrary Python supported encoding.

   - Major improvements to printing of NumPy arrays and scalars.


*New functions*

   - ``parametrize``: decorator added to numpy.testing


   - ``chebinterpolate``: Interpolate function at Chebyshev points.


   - ``format_float_positional`` and ``format_float_scientific`` : format
   floating-point scalars unambiguously with control of rounding and padding.


   - ``PyArray_ResolveWritebackIfCopy`` and ``PyArray_SetWritebackIfCopyBase``,
   new C-API functions useful in achieving PyPy compatibity.
