Nadav: Can you provide a testcase that fails?

I don't think you're correct - it works just fine when `axis = a.ndims` - the issue arises when `axis > a.ndims`, but I'd argue that in that case an error is correct behaviour. But still a change, so perhaps needs a release note entry

There is a change to "expand_dims" function, that it is now does not allow axis = a.ndims.

This influences matplotlib function get_bending_matrices in triinterpolate.py

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

*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 <https://github.com/numpy/numpy/releases/tag/v1.13.0rc1>.
