Hi All,
I'm please to announce the NumPy 1.13.0rc1 release. This release
supports Python 2.7 and 3.4-3.6 and contains many new features. It is
one of the most ambitious releases in the last several years. Some of
the highlights and new functions are
I found this strange behavior:
(np113) [jensj@ASUS np113]$ python3
Python 3.5.3 (default, Jan 19 2017, 14:11:04)
[GCC 6.3.0 20170118] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> np.__version__
'1.13.0rc1'
>>> s = (27, 27, 27)
>>> x = np.ones(s, complex)
>>> y = np.zeros(s)
>>> y += abs(x * 2.0)**2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: Cannot cast ufunc add output from dtype('complex128') to
dtype('float64') with casting rule 'same_kind'
Works OK with s=(3,3,3).

*Highlights*
* Operations like ``a + b + c`` will reuse temporaries on some
platforms, resulting in less memory use and faster execution.
* Inplace operations check if inputs overlap outputs and create
temporaries to avoid problems.
* New __array_ufunc__ attribute provides improved ability for
classes to override default ufunc behavior.
* New np.block function for creating blocked arrays.
*New functions*
* New ``np.positive`` ufunc.
* New ``np.divmod`` ufunc provides more efficient divmod.
* New ``np.isnat`` ufunc tests for NaT special values.
* New ``np.heaviside`` ufunc computes the Heaviside function.
* New ``np.isin`` function, improves on ``in1d``.
* New ``np.block`` function for creating blocked arrays.
* New ``PyArray_MapIterArrayCopyIfOverlap`` added to NumPy C-API.
Wheels for the pre-release are available on PyPI. Source tarballs,
zipfiles, release notes, and the Changelog are available on github
