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 <>.  Source tarballs,
zipfiles, release notes, and the changelog are available on github

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
<>. 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.
