Hi All,

I'm pleased to announce the NumPy 1.12.0rc2 New Year's release. This release 
supports Python 2.7 and 3.4-3.6. Wheels for all supported Python versions may 
be downloaded from PiPY
<>, the tarball
and zip files may be downloaded from Github
<>. The release notes
and files hashes may also be found at Github
<> .

NumPy 1.12.0rc 2 is the result of 413 pull requests submitted by 139 
contributors and comprises a large number of fixes and improvements. Among the 
many improvements it is difficult to  pick out just a few as standing above the 
others, but the following may be of particular interest or indicate areas 
likely to have future consequences.

* Order of operations in ``np.einsum`` can now be optimized for large speed
* New ``signature`` argument to ``np.vectorize`` for vectorizing with core
* The ``keepdims`` argument was added to many functions.
* New context manager for testing warnings
* Support for BLIS in numpy.distutils
* Much improved support for PyPy (not yet finished)
