Hi All, I am pleased to announce the release of NumPy 1.12.0rc1. This release supports Python 2.7 and 3.4 - 3.6 and is the result of 406 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 improvements. * New ``signature`` argument to ``np.vectorize`` for vectorizing with core dimensions. * 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) The release notes are quite sizable and rather than put them inline I've attached them as a file. They may also be viewed at Github <https://github.com/numpy/numpy/releases/tag/v1.12.0rc1>. Zip files and tarballs may also be found the Github link. Wheels and a zip archive are available from PyPI, which is the recommended method of installation. Cheers, Charles Harris
