Hi All, On behalf of the NumPy team, I am pleased to announce the release of NumPy 1.13.1. This is a bugfix release for problems found in 1.13.0. The major changes are: - fixes for the new memory overlap detection, - fixes for the new temporary elision capability, - reversion of the removal of the boolean binary ``-`` operator. It is recommended that users of 1.13.0 upgrade to 1.13.1. Wheels can be found on PyPI <https://pypi.python.org/pypi/numpy>. Source tarballs, zipfiles, release notes, and the changelog are available on github <https://github.com/numpy/numpy/releases/tag/v1.13.1>. Note that the wheels for Python 3.6 are built against 3.6.1, hence will not work when used with 3.6.0 due to Python bug #29943 <https://bugs.python.org/issue29943>. The plan is to release NumPy 1.13.2 shortly after the release of Python 3.6.2 is out with a fix that problem. If you are using 3.6.0, the workaround is to upgrade to 3.6.1 or use an earlier Python version. *Pull requests merged*A total of 19 pull requests were merged for this release. * #9240 DOC: BLD: fix lots of Sphinx warnings/errors. * #9255 Revert "DEP: Raise TypeError for subtract(bool_, bool_)." * #9261 BUG: don't elide into readonly and updateifcopy temporaries for... * #9262 BUG: fix missing keyword rename for common block in numpy.f2py * #9263 BUG: handle resize of 0d array * #9267 DOC: update f2py front page and some doc build metadata. * #9299 BUG: Fix Intel compilation on Unix. * #9317 BUG: fix wrong ndim used in empty where check * #9319 BUG: Make extensions compilable with MinGW on Py2.7 * #9339 BUG: Prevent crash if ufunc doc string is null * #9340 BUG: umath: un-break ufunc where= when no out= is given * #9371 DOC: Add isnat/positive ufunc to documentation * #9372 BUG: Fix error in fromstring function from numpy.core.records... * #9373 BUG: ')' is printed at the end pointer of the buffer in numpy.f2py. * #9374 DOC: Create NumPy 1.13.1 release notes. * #9376 BUG: Prevent hang traversing ufunc userloop linked list * #9377 DOC: Use x1 and x2 in the heaviside docstring. * #9378 DOC: Add $PARAMS to the isnat docstring * #9379 DOC: Update the 1.13.1 release notes *Contributors* A total of 12 people contributed to this release.
