The Windows problems +addressed are: + +- DLL load problems for NumPy wheels on Windows, +- distutils command line parsing on Windows. + +There is also a regression fix correcting signed zeros produced by divmod, see +below for details. + +Downstream developers building this release should use Cython >= 0.29.2 and, if +using OpenBLAS, OpenBLAS > v0.3.4. + +If you are installing using pip, you may encounter a problem with older +installed versions of NumPy that pip did not delete becoming mixed with the +current version, resulting in an ``ImportError``. That problem is particularly +common on Debian derived distributions due to a modified pip. The fix is to +make sure all previous NumPy versions installed by pip have been removed. See +`#12736 <https://github.com/numpy/numpy/issues/12736>`__ for discussion of the +issue. + + +Compatibility notes +=================== + +Signed zero when using divmod +----------------------------- +Starting in version 1.12.0, numpy incorrectly returned a negatively signed zero +when using the ``divmod`` and ``floor_divide`` functions when the result was +zero. For example:: + + >>> np.zeros(10)//1 + array([-0., -0., -0., -0., -0., -0., -0., -0., -0., -0.]) + +With this release, the result is correctly returned as a positively signed +zero:: + + >>> np.zeros(10)//1 + array([0., 0., 0., 0., 0., 0., 0., 0., 0., 0.]) + + +Contributors +============ + +A total of 5 people contributed to this release.
